This file is maintained and copyrighted by M. Warner Losh . See end of file for further details. For commonly done items, please see the COMMON ITEMS: section later in the file. These instructions assume that you basically know what you are doing. If not, then please consult the FreeBSD handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html Items affecting the ports and packages system can be found in /usr/ports/UPDATING. Please read that file before running portupgrade. NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to the tip of head, and then rebuild without this option. The bootstrap process from older version of current across the gcc/clang cutover is a bit fragile. NOTE TO PEOPLE WHO THINK THAT FreeBSD 11.x IS SLOW: FreeBSD 11.x has many debugging features turned on, in both the kernel and userland. These features attempt to detect incorrect use of system primitives, and encourage loud failure through extra sanity checking and fail stop semantics. They also substantially impact system performance. If you want to do performance measurement, benchmarking, and optimization, you'll want to turn them off. This includes various WITNESS- related kernel options, INVARIANTS, malloc debugging flags in userland, and various verbose features in the kernel. Many developers choose to disable these features on build machines to maximize performance. (To completely disable malloc debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely disable the most expensive debugging functionality run "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 2015mmdd: Clang and llvm have been upgraded to 3.7.0. Please see the 20141231 entry below for information about prerequisites and upgrading, if you are not already using 3.5.0 or higher. +20150924: + Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, + and renamed from .symbols to .debug. This reduces the size requirements + on the boot partition or file system and provides consistency with + userland debug files. + + When using the supported kernel installation method the + /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) + as is done with /boot/kernel. + + Developers wishing to maintain the historical behavior of installing + debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). + 20150827: The wireless drivers had undergone changes that remove the 'parent interface' from the ifconfig -l output. The rc.d network scripts used to check presence of a parent interface in the list, so old scripts would fail to start wireless networking. Thus, etcupdate(3) or mergemaster(8) run is required after kernel update, to update your rc.d scripts in /etc. 20150827: pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' These configurations are now automatically interpreted as 'scrub fragment reassemble'. 20150817: Kernel-loadable modules for the random(4) device are back. To use them, the kernel must have device random options RANDOM_LOADABLE kldload(8) can then be used to load random_fortuna.ko or random_yarrow.ko. Please note that due to the indirect function calls that the loadable modules need to provide, the build-in variants will be slightly more efficient. The random(4) kernel option RANDOM_DUMMY has been retired due to unpopularity. It was not all that useful anyway. 20150813: The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. Control over building the ELF Tool Chain tools is now provided by the WITHOUT_TOOLCHAIN knob. 20150810: The polarity of Pulse Per Second (PPS) capture events with the uart(4) driver has been corrected. Prior to this change the PPS "assert" event corresponded to the trailing edge of a positive PPS pulse and the "clear" event was the leading edge of the next pulse. As the width of a PPS pulse in a typical GPS receiver is on the order of 1 millisecond, most users will not notice any significant difference with this change. Anyone who has compensated for the historical polarity reversal by configuring a negative offset equal to the pulse width will need to remove that workaround. 20150809: The default group assigned to /dev/dri entries has been changed from 'wheel' to 'video' with the id of '44'. If you want to have access to the dri devices please add yourself to the video group with: # pw groupmod video -m $USER 20150806: The menu.rc and loader.rc files will now be replaced during upgrades. Please migrate local changes to menu.rc.local and loader.rc.local instead. 20150805: GNU Binutils versions of addr2line, c++filt, nm, readelf, size, strings and strip have been removed. The src.conf(5) knob WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 20150728: As ZFS requires more kernel stack pages than is the default on some architectures e.g. i386, it now warns if KSTACK_PAGES is less than ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). Please consider using 'options KSTACK_PAGES=X' where X is greater than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 20150706: sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by default, i.e., they will not contain "::". For example, instead of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet to have a more specific match, such as different map entries for IPv6:0:0 vs IPv6:0. This change requires that configuration data (including maps, files, classes, custom ruleset, etc.) must use the same format, so make certain such configuration data is upgrading. As a very simple check search for patterns like 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or the cf option UseCompressedIPv6Addresses. 20150630: The default kernel entropy-processing algorithm is now Fortuna, replacing Yarrow. Assuming you have 'device random' in your kernel config file, the configurations allow a kernel option to override this default. You may choose *ONE* of: options RANDOM_YARROW # Legacy /dev/random algorithm. options RANDOM_DUMMY # Blocking-only driver. If you have neither, you get Fortuna. For most people, read no further, Fortuna will give a /dev/random that works like it always used to, and the difference will be irrelevant. If you remove 'device random', you get *NO* kernel-processed entopy at all. This may be acceptable to folks building embedded systems, but has complications. Carry on reading, and it is assumed you know what you need. *PLEASE* read random(4) and random(9) if you are in the habit of tweeking kernel configs, and/or if you are a member of the embedded community, wanting specific and not-usual behaviour from your security subsystems. NOTE!! If you use RANDOM_DUMMY and/or have no 'device random', you will NOT have a functioning /dev/random, and many cryptographic features will not work, including SSH. You may also find strange behaviour from the random(3) set of library functions, in particular sranddev(3), srandomdev(3) and arc4random(3). The reason for this is that the KERN_ARND sysctl only returns entropy if it thinks it has some to share, and with RANDOM_DUMMY or no 'device random' this will never happen. 20150623: An additional fix for the issue described in the 20150614 sendmail entry below has been been committed in revision 284717. 20150616: FreeBSD's old make (fmake) has been removed from the system. It is available as the devel/fmake port or via pkg install fmake. 20150615: The fix for the issue described in the 20150614 sendmail entry below has been been committed in revision 284436. The work around described in that entry is no longer needed unless the default setting is overridden by a confDH_PARAMETERS configuration setting of '5' or pointing to a 512 bit DH parameter file. 20150614: ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf and devel/kyua to version 0.20+ and adjust any calling code to work with Kyuafile and kyua. 20150614: The import of openssl to address the FreeBSD-SA-15:10.openssl security advisory includes a change which rejects handshakes with DH parameters below 768 bits. sendmail releases prior to 8.15.2 (not yet released), defaulted to a 512 bit DH parameter setting for client connections. To work around this interoperability, sendmail can be configured to use a 2048 bit DH parameter by: 1. Edit /etc/mail/`hostname`.mc 2. If a setting for confDH_PARAMETERS does not exist or exists and is set to a string beginning with '5', replace it with '2'. 3. If a setting for confDH_PARAMETERS exists and is set to a file path, create a new file with: openssl dhparam -out /path/to/file 2048 4. Rebuild the .cf file: cd /etc/mail/; make; make install 5. Restart sendmail: cd /etc/mail/; make restart A sendmail patch is coming, at which time this file will be updated. 20150604: Generation of legacy formatted entries have been disabled by default in pwd_mkdb(8), as all base system consumers of the legacy formatted entries were converted to use the new format by default when the new, machine independent format have been added and supported since FreeBSD 5.x. Please see the pwd_mkdb(8) manual page for further details. 20150525: Clang and llvm have been upgraded to 3.6.1 release. Please see the 20141231 entry below for information about prerequisites and upgrading, if you are not already using 3.5.0 or higher. 20150521: TI platform code switched to using vendor DTS files and this update may break existing systems running on Beaglebone, Beaglebone Black, and Pandaboard: - dtb files should be regenerated/reinstalled. Filenames are the same but content is different now - GPIO addressing was changed, now each GPIO bank (32 pins per bank) has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25 on /dev/gpioc3. - Pandaboard: /etc/ttys should be updated, serial console device is now /dev/ttyu2, not /dev/ttyu0 20150501: soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. If you need the GNU extension from groff soelim(1), install groff from package: pkg install groff, or via ports: textproc/groff. 20150423: chmod, chflags, chown and chgrp now affect symlinks in -R mode as defined in symlink(7); previously symlinks were silently ignored. 20150415: The const qualifier has been removed from iconv(3) to comply with POSIX. The ports tree is aware of this from r384038 onwards. 20150416: Libraries specified by LIBADD in Makefiles must have a corresponding DPADD_ variable to ensure correct dependencies. This is now enforced in src.libnames.mk. 20150324: From legacy ata(4) driver was removed support for SATA controllers supported by more functional drivers ahci(4), siis(4) and mvs(4). Kernel modules ataahci and ataadaptec were removed completely, replaced by ahci and mvs modules respectively. 20150315: Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see the 20141231 entry below for information about prerequisites and upgrading, if you are not already using 3.5.0 or higher. 20150307: The 32-bit PowerPC kernel has been changed to a position-independent executable. This can only be booted with a version of loader(8) newer than January 31, 2015, so make sure to update both world and kernel before rebooting. 20150217: If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), but before r278950, the RNG was not seeded properly. Immediately upgrade the kernel to r278950 or later and regenerate any keys (e.g. ssh keys or openssl keys) that were generated w/ a kernel from that range. This does not affect programs that directly used /dev/random or /dev/urandom. All userland uses of arc4random(3) are affected. 20150210: The autofs(4) ABI was changed in order to restore binary compatibility with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work with the new kernel. 20150131: The powerpc64 kernel has been changed to a position-independent executable. This can only be booted with a new version of loader(8), so make sure to update both world and kernel before rebooting. 20150118: Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix only release, no new features have been added. Please see the 20141231 entry below for information about prerequisites and upgrading, if you are not already using 3.5.0. 20150107: ELF tools addr2line, elfcopy (strip), nm, size, and strings are now taken from the ELF Tool Chain project rather than GNU binutils. They should be drop-in replacements, with the addition of arm64 support. The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the binutils tools, if necessary. See 20150805 for updated information. 20150105: The default Unbound configuration now enables remote control using a local socket. Users who have already enabled the local_unbound service should regenerate their configuration by running "service local_unbound setup" as root. 20150102: The GNU texinfo and GNU info pages have been removed. To be able to view GNU info pages please install texinfo from ports. 20141231: Clang, llvm and lldb have been upgraded to 3.5.0 release. As of this release, a prerequisite for building clang, llvm and lldb is a C++11 capable compiler and C++11 standard library. This means that to be able to successfully build the cross-tools stage of buildworld, with clang as the bootstrap compiler, your system compiler or cross compiler should either be clang 3.3 or later, or gcc 4.8 or later, and your system C++ library should be libc++, or libdstdc++ from gcc 4.8 or later. On any standard FreeBSD 10.x or 11.x installation, where clang and libc++ are on by default (that is, on x86 or arm), this should work out of the box. On 9.x installations where clang is enabled by default, e.g. on x86 and powerpc, libc++ will not be enabled by default, so libc++ should be built (with clang) and installed first. If both clang and libc++ are missing, build clang first, then use it to build libc++. On 8.x and earlier installations, upgrade to 9.x first, and then follow the instructions for 9.x above. Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by default, and do not build clang. Many embedded systems are resource constrained, and will not be able to build clang in a reasonable time, or in some cases at all. In those cases, cross building bootable systems on amd64 is a workaround. This new version of clang introduces a number of new warnings, of which the following are most likely to appear: -Wabsolute-value This warns in two cases, for both C and C++: * When the code is trying to take the absolute value of an unsigned quantity, which is effectively a no-op, and almost never what was intended. The code should be fixed, if at all possible. If you are sure that the unsigned quantity can be safely cast to signed, without loss of information or undefined behavior, you can add an explicit cast, or disable the warning. * When the code is trying to take an absolute value, but the called abs() variant is for the wrong type, which can lead to truncation. If you want to disable the warning instead of fixing the code, please make sure that truncation will not occur, or it might lead to unwanted side-effects. -Wtautological-undefined-compare and -Wundefined-bool-conversion These warn when C++ code is trying to compare 'this' against NULL, while 'this' should never be NULL in well-defined C++ code. However, there is some legacy (pre C++11) code out there, which actively abuses this feature, which was less strictly defined in previous C++ versions. Squid and openjdk do this, for example. The warning can be turned off for C++98 and earlier, but compiling the code in C++11 mode might result in unexpected behavior; for example, the parts of the program that are unreachable could be optimized away. 20141222: The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) kernel sources have been removed. The .h files remain, since some utilities include them. This will need to be fixed later. If "mount -t oldnfs ..." is attempted, it will fail. If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, the utilities will report errors. 20141121: The handling of LOCAL_LIB_DIRS has been altered to skip addition of directories to top level SUBDIR variable when their parent directory is included in LOCAL_DIRS. Users with build systems with such hierarchies and without SUBDIR entries in the parent directory Makefiles should add them or add the directories to LOCAL_DIRS. 20141109: faith(4) and faithd(8) have been removed from the base system. Faith has been obsolete for a very long time. 20141104: vt(4), the new console driver, is enabled by default. It brings support for Unicode and double-width characters, as well as support for UEFI and integration with the KMS kernel video drivers. You may need to update your console settings in /etc/rc.conf, most probably the keymap. During boot, /etc/rc.d/syscons will indicate what you need to do. vt(4) still has issues and lacks some features compared to syscons(4). See the wiki for up-to-date information: https://wiki.freebsd.org/Newcons If you want to keep using syscons(4), you can do so by adding the following line to /boot/loader.conf: kern.vty=sc 20141102: pjdfstest has been integrated into kyua as an opt-in test suite. Please see share/doc/pjdfstest/README for more details on how to execute it. 20141009: gperf has been removed from the base system for architectures that use clang. Ports that require gperf will obtain it from the devel/gperf port. 20140923: pjdfstest has been moved from tools/regression/pjdfstest to contrib/pjdfstest . 20140922: At svn r271982, The default linux compat kernel ABI has been adjusted to 2.6.18 in support of the linux-c6 compat ports infrastructure update. If you wish to continue using the linux-f10 compat ports, add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are encouraged to update their linux-compat packages to linux-c6 during their next update cycle. 20140729: The ofwfb driver, used to provide a graphics console on PowerPC when using vt(4), no longer allows mmap() of all physical memory. This will prevent Xorg on PowerPC with some ATI graphics cards from initializing properly unless x11-servers/xorg-server is updated to 1.12.4_8 or newer. 20140723: The xdev targets have been converted to using TARGET and TARGET_ARCH instead of XDEV and XDEV_ARCH. 20140719: The default unbound configuration has been modified to address issues with reverse lookups on networks that use private address ranges. If you use the local_unbound service, run "service local_unbound setup" as root to regenerate your configuration, then "service local_unbound reload" to load the new configuration. 20140709: The GNU texinfo and GNU info pages are not built and installed anymore, WITH_INFO knob has been added to allow to built and install them again. UPDATE: see 20150102 entry on texinfo's removal 20140708: The GNU readline library is now an INTERNALLIB - that is, it is statically linked into consumers (GDB and variants) in the base system, and the shared library is no longer installed. The devel/readline port is available for third party software that requires readline. 20140702: The Itanium architecture (ia64) has been removed from the list of known architectures. This is the first step in the removal of the architecture. 20140701: Commit r268115 has added NFSv4.1 server support, merged from projects/nfsv4.1-server. Since this includes changes to the internal interfaces between the NFS related modules, a full build of the kernel and modules will be necessary. __FreeBSD_version has been bumped. 20140629: The WITHOUT_VT_SUPPORT kernel config knob has been renamed WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning which differs from the behaviour controlled by this knob.) 20140619: Maximal length of the serial number in CTL was increased from 16 to 64 chars, that breaks ABI. All CTL-related tools, such as ctladm and ctld, need to be rebuilt to work with a new kernel. 20140606: The libatf-c and libatf-c++ major versions were downgraded to 0 and 1 respectively to match the upstream numbers. They were out of sync because, when they were originally added to FreeBSD, the upstream versions were not respected. These libraries are private and not yet built by default, so renumbering them should be a non-issue. However, unclean source trees will yield broken test programs once the operator executes "make delete-old-libs" after a "make installworld". Additionally, the atf-sh binary was made private by moving it into /usr/libexec/. Already-built shell test programs will keep the path to the old binary so they will break after "make delete-old" is run. If you are using WITH_TESTS=yes (not the default), wipe the object tree and rebuild from scratch to prevent spurious test failures. This is only needed once: the misnumbered libraries and misplaced binaries have been added to OptionalObsoleteFiles.inc so they will be removed during a clean upgrade. 20140512: Clang and llvm have been upgraded to 3.4.1 release. 20140508: We bogusly installed src.opts.mk in /usr/share/mk. This file should be removed to avoid issues in the future (and has been added to ObsoleteFiles.inc). 20140505: /etc/src.conf now affects only builds of the FreeBSD src tree. In the past, it affected all builds that used the bsd.*.mk files. The old behavior was a bug, but people may have relied upon it. To get this behavior back, you can .include /etc/src.conf from /etc/make.conf (which is still global and isn't changed). This also changes the behavior of incremental builds inside the tree of individual directories. Set MAKESYSPATH to ".../share/mk" to do that. Although this has survived make universe and some upgrade scenarios, other upgrade scenarios may have broken. At least one form of temporary breakage was fixed with MAKESYSPATH settings for buildworld as well... In cases where MAKESYSPATH isn't working with this setting, you'll need to set it to the full path to your tree. One side effect of all this cleaning up is that bsd.compiler.mk is no longer implicitly included by bsd.own.mk. If you wish to use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk as well. 20140430: The lindev device has been removed since /dev/full has been made a standard device. __FreeBSD_version has been bumped. 20140424: The knob WITHOUT_VI was added to the base system, which controls building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) in order to reorder files share/termcap and didn't build ex(1) as a build tool, so building/installing with WITH_VI is highly advised for build hosts for older releases. This issue has been fixed in stable/9 and stable/10 in r277022 and r276991, respectively. 20140418: The YES_HESIOD knob has been removed. It has been obsolete for a decade. Please move to using WITH_HESIOD instead or your builds will silently lack HESIOD. 20140405: The uart(4) driver has been changed with respect to its handling of the low-level console. Previously the uart(4) driver prevented any process from changing the baudrate or the CLOCAL and HUPCL control flags. By removing the restrictions, operators can make changes to the serial console port without having to reboot. However, when getty(8) is started on the serial device that is associated with the low-level console, a misconfigured terminal line in /etc/ttys will now have a real impact. Before upgrading the kernel, make sure that /etc/ttys has the serial console device configured as 3wire without baudrate to preserve the previous behaviour. E.g: ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 20140306: Support for libwrap (TCP wrappers) in rpcbind was disabled by default to improve performance. To re-enable it, if needed, run rpcbind with command line option -W. 20140226: Switched back to the GPL dtc compiler due to updates in the upstream dts files not being supported by the BSDL dtc compiler. You will need to rebuild your kernel toolchain to pick up the new compiler. Core dumps may result while building dtb files during a kernel build if you fail to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 20140216: Clang and llvm have been upgraded to 3.4 release. 20140216: The nve(4) driver has been removed. Please use the nfe(4) driver for NVIDIA nForce MCP Ethernet adapters instead. 20140212: An ABI incompatibility crept into the libc++ 3.4 import in r261283. This could cause certain C++ applications using shared libraries built against the previous version of libc++ to crash. The incompatibility has now been fixed, but any C++ applications or shared libraries built between r261283 and r261801 should be recompiled. 20140204: OpenSSH will now ignore errors caused by kernel lacking of Capsicum capability mode support. Please note that enabling the feature in kernel is still highly recommended. 20140131: OpenSSH is now built with sandbox support, and will use sandbox as the default privilege separation method. This requires Capsicum capability mode support in kernel. 20140128: The libelf and libdwarf libraries have been updated to newer versions from upstream. Shared library version numbers for these two libraries were bumped. Any ports or binaries requiring these two libraries should be recompiled. __FreeBSD_version is bumped to 1100006. 20140110: If a Makefile in a tests/ directory was auto-generating a Kyuafile instead of providing an explicit one, this would prevent such Makefile from providing its own Kyuafile in the future during NO_CLEAN builds. This has been fixed in the Makefiles but manual intervention is needed to clean an objdir if you use NO_CLEAN: # find /usr/obj -name Kyuafile | xargs rm -f 20131213: The behavior of gss_pseudo_random() for the krb5 mechanism has changed, for applications requesting a longer random string than produced by the underlying enctype's pseudo-random() function. In particular, the random string produced from a session key of enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will be different at the 17th octet and later, after this change. The counter used in the PRF+ construction is now encoded as a big-endian integer in accordance with RFC 4402. __FreeBSD_version is bumped to 1100004. 20131108: The WITHOUT_ATF build knob has been removed and its functionality has been subsumed into the more generic WITHOUT_TESTS. If you were using the former to disable the build of the ATF libraries, you should change your settings to use the latter. 20131025: The default version of mtree is nmtree which is obtained from NetBSD. The output is generally the same, but may vary slightly. If you found you need identical output adding "-F freebsd9" to the command line should do the trick. For the time being, the old mtree is available as fmtree. 20131014: libbsdyml has been renamed to libyaml and moved to /usr/lib/private. This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1.1.4_8 and verify bsdyml not linked in, before running "make delete-old-libs": # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean or # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 20131010: The stable/10 branch has been created in subversion from head revision r256279. 20131010: The rc.d/jail script has been updated to support jail(8) configuration file. The "jail__*" rc.conf(5) variables for per-jail configuration are automatically converted to /var/run/jail..conf before the jail(8) utility is invoked. This is transparently backward compatible. See below about some incompatibilities and rc.conf(5) manual page for more details. These variables are now deprecated in favor of jail(8) configuration file. One can use "rc.d/jail config " command to generate a jail(8) configuration file in /var/run/jail..conf without running the jail(8) utility. The default pathname of the configuration file is /etc/jail.conf and can be specified by using $jail_conf or $jail__conf variables. Please note that jail_devfs_ruleset accepts an integer at this moment. Please consider to rewrite the ruleset name with an integer. 20130930: BIND has been removed from the base system. If all you need is a local resolver, simply enable and start the local_unbound service instead. Otherwise, several versions of BIND are available in the ports tree. The dns/bind99 port is one example. With this change, nslookup(1) and dig(1) are no longer in the base system. Users should instead use host(1) and drill(1) which are in the base system. Alternatively, nslookup and dig can be obtained by installing the dns/bind-tools port. 20130916: With the addition of unbound(8), a new unbound user is now required during installworld. "mergemaster -p" can be used to add the user prior to installworld, as documented in the handbook. 20130911: OpenSSH is now built with DNSSEC support, and will by default silently trust signed SSHFP records. This can be controlled with the VerifyHostKeyDNS client configuration setting. DNSSEC support can be disabled entirely with the WITHOUT_LDNS option in src.conf. 20130906: The GNU Compiler Collection and C++ standard library (libstdc++) are no longer built by default on platforms where clang is the system compiler. You can enable them with the WITH_GCC and WITH_GNUCXX options in src.conf. 20130905: The PROCDESC kernel option is now part of the GENERIC kernel configuration and is required for the rwhod(8) to work. If you are using custom kernel configuration, you should include 'options PROCDESC'. 20130905: The API and ABI related to the Capsicum framework was modified in backward incompatible way. The userland libraries and programs have to be recompiled to work with the new kernel. This includes the following libraries and programs, but the whole buildworld is advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, kdump, procstat, rwho, rwhod, uniq. 20130903: AES-NI intrinsic support has been added to gcc. The AES-NI module has been updated to use this support. A new gcc is required to build the aesni module on both i386 and amd64. 20130821: The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. Thus "device padlock_rng" and "device rdrand_rng" should be used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 20130813: WITH_ICONV has been split into two feature sets. WITH_ICONV now enables just the iconv* functionality and is now on by default. WITH_LIBICONV_COMPAT enables the libiconv api and link time compatability. Set WITHOUT_ICONV to build the old way. If you have been using WITH_ICONV before, you will very likely need to turn on WITH_LIBICONV_COMPAT. 20130806: INVARIANTS option now enables DEBUG for code with OpenSolaris and Illumos origin, including ZFS. If you have INVARIANTS in your kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG explicitly. DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) locks if WITNESS option was set. Because that generated a lot of witness(9) reports and all of them were believed to be false positives, this is no longer done. New option OPENSOLARIS_WITNESS can be used to achieve the previous behavior. 20130806: Timer values in IPv6 data structures now use time_uptime instead of time_second. Although this is not a user-visible functional change, userland utilities which directly use them---ndp(8), rtadvd(8), and rtsold(8) in the base system---need to be updated to r253970 or later. 20130802: find -delete can now delete the pathnames given as arguments, instead of only files found below them or if the pathname did not contain any slashes. Formerly, the following error message would result: find: -delete: : relative path potentially not safe Deleting the pathnames given as arguments can be prevented without error messages using -mindepth 1 or by changing directory and passing "." as argument to find. This works in the old as well as the new version of find. 20130726: Behavior of devfs rules path matching has been changed. Pattern is now always matched against fully qualified devfs path and slash characters must be explicitly matched by slashes in pattern (FNM_PATHNAME). Rulesets involving devfs subdirectories must be reviewed. 20130716: The default ARM ABI has changed to the ARM EABI. The old ABI is incompatible with the ARM EABI and all programs and modules will need to be rebuilt to work with a new kernel. To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. NOTE: Support for the old ABI will be removed in the future and users are advised to upgrade. 20130709: pkg_install has been disconnected from the build if you really need it you should add WITH_PKGTOOLS in your src.conf(5). 20130709: Most of network statistics structures were changed to be able keep 64-bits counters. Thus all tools, that work with networking statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 20130629: Fix targets that run multiple make's to use && rather than ; so that subsequent steps depend on success of previous. NOTE: if building 'universe' with -j* on stable/8 or stable/9 it would be better to start the build using bmake, to avoid overloading the machine. 20130618: Fix a bug that allowed a tracing process (e.g. gdb) to write to a memory-mapped file in the traced process's address space even if neither the traced process nor the tracing process had write access to that file. 20130615: CVS has been removed from the base system. An exact copy of the code is available from the devel/cvs port. 20130613: Some people report the following error after the switch to bmake: make: illegal option -- J usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] ... *** [buildworld] Error code 2 this likely due to an old instance of make in ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) which src/Makefile will use that blindly, if it exists, so if you see the above error: rm -rf `make -V MAKEPATH` should resolve it. 20130516: Use bmake by default. Whereas before one could choose to build with bmake via -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old make. The goal is to remove these knobs for 10-RELEASE. It is worth noting that bmake (like gmake) treats the command line as the unit of failure, rather than statements within the command line. Thus '(cd some/where && dosomething)' is safer than 'cd some/where; dosomething'. The '()' allows consistent behavior in parallel build. 20130429: Fix a bug that allows NFS clients to issue READDIR on files. 20130426: The WITHOUT_IDEA option has been removed because the IDEA patent expired. 20130426: The sysctl which controls TRIM support under ZFS has been renamed from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been enabled by default. 20130425: The mergemaster command now uses the default MAKEOBJDIRPREFIX rather than creating it's own in the temporary directory in order allow access to bootstrapped versions of tools such as install and mtree. When upgrading from version of FreeBSD where the install command does not support -l, you will need to install a new mergemaster command if mergemaster -p is required. This can be accomplished with the command (cd src/usr.sbin/mergemaster && make install). 20130404: Legacy ATA stack, disabled and replaced by new CAM-based one since FreeBSD 9.0, completely removed from the sources. Kernel modules atadisk and atapi*, user-level tools atacontrol and burncd are removed. Kernel option `options ATA_CAM` is now permanently enabled and removed. 20130319: SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) and socketpair(2). Software, in particular Kerberos, may automatically detect and use these during building. The resulting binaries will not work on older kernels. 20130308: CTL_DISABLE has also been added to the sparc64 GENERIC (for further information, see the respective 20130304 entry). 20130304: Recent commits to callout(9) changed the size of struct callout, so the KBI is probably heavily disturbed. Also, some functions in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced by macros. Every kernel module using it won't load, so rebuild is requested. The ctl device has been re-enabled in GENERIC for i386 and amd64, but does not initialize by default (because of the new CTL_DISABLE option) to save memory. To re-enable it, remove the CTL_DISABLE option from the kernel config file or set kern.cam.ctl.disable=0 in /boot/loader.conf. 20130301: The ctl device has been disabled in GENERIC for i386 and amd64. This was done due to the extra memory being allocated at system initialisation time by the ctl driver which was only used if a CAM target device was created. This makes a FreeBSD system unusable on 128MB or less of RAM. 20130208: A new compression method (lz4) has been merged to -HEAD. Please refer to zpool-features(7) for more information. Please refer to the "ZFS notes" section of this file for information on upgrading boot ZFS pools. 20130129: A BSD-licensed patch(1) variant has been added and is installed as bsdpatch, being the GNU version the default patch. To inverse the logic and use the BSD-licensed one as default, while having the GNU version installed as gnupatch, rebuild and install world with the WITH_BSD_PATCH knob set. 20130121: Due to the use of the new -l option to install(1) during build and install, you must take care not to directly set the INSTALL make variable in your /etc/make.conf, /etc/src.conf, or on the command line. If you wish to use the -C flag for all installs you may be able to add INSTALL+=-C to /etc/make.conf or /etc/src.conf. 20130118: The install(1) option -M has changed meaning and now takes an argument that is a file or path to append logs to. In the unlikely event that -M was the last option on the command line and the command line contained at least two files and a target directory the first file will have logs appended to it. The -M option served little practical purpose in the last decade so its use is expected to be extremely rare. 20121223: After switching to Clang as the default compiler some users of ZFS on i386 systems started to experience stack overflow kernel panics. Please consider using 'options KSTACK_PAGES=4' in such configurations. 20121222: GEOM_LABEL now mangles label names read from file system metadata. Mangling affect labels containing spaces, non-printable characters, '%' or '"'. Device names in /etc/fstab and other places may need to be updated. 20121217: By default, only the 10 most recent kernel dumps will be saved. To restore the previous behaviour (no limit on the number of kernel dumps stored in the dump directory) add the following line to /etc/rc.conf: savecore_flags="" 20121201: With the addition of auditdistd(8), a new auditdistd user is now required during installworld. "mergemaster -p" can be used to add the user prior to installworld, as documented in the handbook. 20121117: The sin6_scope_id member variable in struct sockaddr_in6 is now filled by the kernel before passing the structure to the userland via sysctl or routing socket. This means the KAME-specific embedded scope id in sin6_addr.s6_addr[2] is always cleared in userland application. This behavior can be controlled by net.inet6.ip6.deembed_scopeid. __FreeBSD_version is bumped to 1000025. 20121105: On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. This means that the world and kernel will be compiled with clang and that clang will be installed as /usr/bin/cc, /usr/bin/c++, and /usr/bin/cpp. To disable this behavior and revert to building with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions of current may need to bootstrap WITHOUT_CLANG first if the clang build fails (its compatibility window doesn't extend to the 9 stable branch point). 20121102: The IPFIREWALL_FORWARD kernel option has been removed. Its functionality now turned on by default. 20121023: The ZERO_COPY_SOCKET kernel option has been removed and split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. NB: SOCKET_SEND_COW uses the VM page based copy-on-write mechanism which is not safe and may result in kernel crashes. NB: The SOCKET_RECV_PFLIP mechanism is useless as no current driver supports disposeable external page sized mbuf storage. Proper replacements for both zero-copy mechanisms are under consideration and will eventually lead to complete removal of the two kernel options. 20121023: The IPv4 network stack has been converted to network byte order. The following modules need to be recompiled together with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), pf(4), ipfw(4), ng_ipfw(4), stf(4). 20121022: Support for non-MPSAFE filesystems was removed from VFS. The VFS_VERSION was bumped, all filesystem modules shall be recompiled. 20121018: All the non-MPSAFE filesystems have been disconnected from the build. The full list includes: codafs, hpfs, ntfs, nwfs, portalfs, smbfs, xfs. 20121016: The interface cloning API and ABI has changed. The following modules need to be recompiled together with kernel: ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 20121015: The sdhci driver was split in two parts: sdhci (generic SD Host Controller logic) and sdhci_pci (actual hardware driver). No kernel config modifications are required, but if you load sdhc as a module you must switch to sdhci_pci instead. 20121014: Import the FUSE kernel and userland support into base system. 20121013: The GNU sort(1) program has been removed since the BSD-licensed sort(1) has been the default for quite some time and no serious problems have been reported. The corresponding WITH_GNU_SORT knob has also gone. 20121006: The pfil(9) API/ABI for AF_INET family has been changed. Packet filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled with new kernel. 20121001: The net80211(4) ABI has been changed to allow for improved driver PS-POLL and power-save support. All wireless drivers need to be recompiled to work with the new kernel. 20120913: The random(4) support for the VIA hardware random number generator (`PADLOCK') is no longer enabled unconditionally. Add the padlock_rng device in the custom kernel config if needed. The GENERIC kernels on i386 and amd64 do include the device, so the change only affects the custom kernel configurations. 20120908: The pf(4) packet filter ABI has been changed. pfctl(8) and snmp_pf module need to be recompiled to work with new kernel. 20120828: A new ZFS feature flag "com.delphix:empty_bpobj" has been merged to -HEAD. Pools that have empty_bpobj in active state can not be imported read-write with ZFS implementations that do not support this feature. For more information read the zpool-features(5) manual page. 20120727: The sparc64 ZFS loader has been changed to no longer try to auto- detect ZFS providers based on diskN aliases but now requires these to be explicitly listed in the OFW boot-device environment variable. 20120712: The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 20120712: The following sysctls and tunables have been renamed for consistency with other variables: kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 20120628: The sort utility has been replaced with BSD sort. For now, GNU sort is also available as "gnusort" or the default can be set back to GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be installed as "bsdsort". 20120611: A new version of ZFS (pool version 5000) has been merged to -HEAD. Starting with this version the old system of ZFS pool versioning is superseded by "feature flags". This concept enables forward compatibility against certain future changes in functionality of ZFS pools. The first read-only compatible "feature flag" for ZFS pools is named "com.delphix:async_destroy". For more information read the new zpool-features(5) manual page. Please refer to the "ZFS notes" section of this file for information on upgrading boot ZFS pools. 20120417: The malloc(3) implementation embedded in libc now uses sources imported as contrib/jemalloc. The most disruptive API change is to /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, delete it prior to installworld, and optionally re-create it using the new format after rebooting. See malloc.conf(5) for details (specifically the TUNING section and the "opt.*" entries in the MALLCTL NAMESPACE section). 20120328: Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is now spelled mips. This is to aid compatibility with third-party software that expects this naming scheme in uname(3). Little-endian settings are unchanged. If you are updating a big-endian mips64 machine from before this change, you may need to set MACHINE_ARCH=mips64 in your environment before the new build system will recognize your machine. 20120306: Disable by default the option VFS_ALLOW_NONMPSAFE for all supported platforms. 20120229: Now unix domain sockets behave "as expected" on nullfs(5). Previously nullfs(5) did not pass through all behaviours to the underlying layer, as a result if we bound to a socket on the lower layer we could connect only to the lower path; if we bound to the upper layer we could connect only to the upper path. The new behavior is one can connect to both the lower and the upper paths regardless what layer path one binds to. 20120211: The getifaddrs upgrade path broken with 20111215 has been restored. If you have upgraded in between 20111215 and 20120209 you need to recompile libc again with your kernel. You still need to recompile world to be able to configure CARP but this restriction already comes from 20111215. 20120114: The set_rcvar() function has been removed from /etc/rc.subr. All base and ports rc.d scripts have been updated, so if you have a port installed with a script in /usr/local/etc/rc.d you can either hand-edit the rcvar= line, or reinstall the port. An easy way to handle the mass-update of /etc/rc.d: rm /etc/rc.d/* && mergemaster -i 20120109: panic(9) now stops other CPUs in the SMP systems, disables interrupts on the current CPU and prevents other threads from running. This behavior can be reverted using the kern.stop_scheduler_on_panic tunable/sysctl. The new behavior can be incompatible with kern.sync_on_panic. 20111215: The carp(4) facility has been changed significantly. Configuration of the CARP protocol via ifconfig(8) has changed, as well as format of CARP events submitted to devd(8) has changed. See manual pages for more information. The arpbalance feature of carp(4) is currently not supported anymore. Size of struct in_aliasreq, struct in6_aliasreq has changed. User utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), need to be recompiled. 20111122: The acpi_wmi(4) status device /dev/wmistat has been renamed to /dev/wmistat0. 20111108: The option VFS_ALLOW_NONMPSAFE option has been added in order to explicitely support non-MPSAFE filesystems. It is on by default for all supported platform at this present time. 20111101: The broken amd(4) driver has been replaced with esp(4) in the amd64, i386 and pc98 GENERIC kernel configuration files. 20110930: sysinstall has been removed 20110923: The stable/9 branch created in subversion. This corresponds to the RELENG_9 branch in CVS. COMMON ITEMS: General Notes ------------- Avoid using make -j when upgrading. While generally safe, there are sometimes problems using -j to upgrade. If your upgrade fails with -j, please try again without -j. From time to time in the past there have been problems using -j with buildworld and/or installworld. This is especially true when upgrading between "distant" versions (eg one that cross a major release boundary or several minor releases, or when several months have passed on the -current branch). Sometimes, obscure build problems are the result of environment poisoning. This can happen because the make utility reads its environment when searching for values for global variables. To run your build attempts in an "environmental clean room", prefix all make commands with 'env -i '. See the env(1) manual page for more details. When upgrading from one major version to another it is generally best to upgrade to the latest code in the currently installed branch first, then do an upgrade to the new branch. This is the best-tested upgrade path, and has the highest probability of being successful. Please try this approach before reporting problems with a major version upgrade. When upgrading a live system, having a root shell around before installing anything can help undo problems. Not having a root shell around can lead to problems if pam has changed too much from your starting point to allow continued authentication after the upgrade. This file should be read as a log of events. When a later event changes information of a prior event, the prior event should not be deleted. Instead, a pointer to the entry with the new information should be placed in the old entry. Readers of this file should also sanity check older entries before relying on them blindly. Authors of new entries should write them with this in mind. ZFS notes --------- When upgrading the boot ZFS pool to a new version, always follow these two steps: 1.) recompile and reinstall the ZFS boot loader and boot block (this is part of "make buildworld" and "make installworld") 2.) update the ZFS boot block on your boot drive The following example updates the ZFS boot block on the first partition (freebsd-boot) of a GPT partitioned drive ada0: "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" Non-boot pools do not need these updates. To build a kernel ----------------- If you are updating from a prior version of FreeBSD (even one just a few days old), you should follow this procedure. It is the most failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, make kernel-toolchain make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE To test a kernel once --------------------- If you just want to boot a kernel once (because you are not sure if it works, or if you want to boot a known bad kernel to provide debugging information) run make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel nextboot -k testkernel To just build a kernel when you know that it won't mess you up -------------------------------------------------------------- This assumes you are already running a CURRENT system. Replace ${arch} with the architecture of your machine (e.g. "i386", "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). cd src/sys/${arch}/conf config KERNEL_NAME_HERE cd ../compile/KERNEL_NAME_HERE make depend make make install If this fails, go to the "To build a kernel" section. To rebuild everything and install it on the current system. ----------------------------------------------------------- # Note: sometimes if you are running current you gotta do more than # is listed here if you are upgrading from a really old current. make buildworld make kernel KERNCONF=YOUR_KERNEL_HERE [1] [3] mergemaster -Fp [5] make installworld mergemaster -Fi [4] make delete-old [6] To cross-install current onto a separate partition -------------------------------------------------- # In this approach we use a separate partition to hold # current's root, 'usr', and 'var' directories. A partition # holding "/", "/usr" and "/var" should be about 2GB in # size. make buildworld make buildkernel KERNCONF=YOUR_KERNEL_HERE make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd To upgrade in-place from stable to current ---------------------------------------------- make buildworld [9] make kernel KERNCONF=YOUR_KERNEL_HERE [8] [1] [3] mergemaster -Fp [5] make installworld mergemaster -Fi [4] make delete-old [6] Make sure that you've read the UPDATING file to understand the tweaks to various things you need. At this point in the life cycle of current, things change often and you are on your own to cope. The defaults can also change, so please read ALL of the UPDATING entries. Also, if you are tracking -current, you must be subscribed to freebsd-current@freebsd.org. Make sure that before you update your sources that you have read and understood all the recent messages there. If in doubt, please track -stable which has much fewer pitfalls. [1] If you have third party modules, such as vmware, you should disable them at this point so they don't crash your system on reboot. [3] From the bootblocks, boot -s, and then do fsck -p mount -u / mount -a cd src adjkerntz -i # if CMOS is wall time Also, when doing a major release upgrade, it is required that you boot into single user mode to do the installworld. [4] Note: This step is non-optional. Failure to do this step can result in a significant reduction in the functionality of the system. Attempting to do it by hand is not recommended and those that pursue this avenue should read this file carefully, as well as the archives of freebsd-current and freebsd-hackers mailing lists for potential gotchas. The -U option is also useful to consider. See mergemaster(8) for more information. [5] Usually this step is a noop. However, from time to time you may need to do this if you get unknown user in the following step. It never hurts to do it all the time. You may need to install a new mergemaster (cd src/usr.sbin/mergemaster && make install) after the buildworld before this step if you last updated from current before 20130425 or from -stable before 20130430. [6] This only deletes old files and directories. Old libraries can be deleted by "make delete-old-libs", but you have to make sure that no program is using those libraries anymore. [8] In order to have a kernel that can run the 4.x binaries needed to do an installworld, you must include the COMPAT_FREEBSD4 option in your kernel. Failure to do so may leave you with a system that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is required to run the 5.x binaries on more recent kernels. And so on for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. Make sure that you merge any new devices from GENERIC since the last time you updated your kernel config file. [9] When checking out sources, you must include the -P flag to have cvs prune empty directories. If CPUTYPE is defined in your /etc/make.conf, make sure to use the "?=" instead of the "=" assignment operator, so that buildworld can override the CPUTYPE if it needs to. MAKEOBJDIRPREFIX must be defined in an environment variable, and not on the command line, or in /etc/make.conf. buildworld will warn if it is improperly defined. FORMAT: This file contains a list, in reverse chronological order, of major breakages in tracking -current. It is not guaranteed to be a complete list of such breakages, and only contains entries since September 23, 2011. If you need to see UPDATING entries from before that date, you will need to fetch an UPDATING file from an older FreeBSD release. Copyright information: Copyright 1998-2009 M. Warner Losh.

Remove unnecessary EXTRA_DIST. * src/Makefile.in: Rerun automake. * src/vasprintf.c (dispatch): Fix variable precision bug: be sure to step past '*'. * src/vasprintf.c (core): Remove unreachable code. * src/apprentice.c (set_test_type): Add cast to avoid compiler warning. 2008-04-22 23:45 Christos Zoulas * Add magic submission guidelines (Abel Cheung) * split msdos and windows magic (Abel Cheung) 2008-04-04 11:00 Christos Zoulas * >= <= is not supported, so fix the magic and warn about it. reported by: Thien-Thi Nguyen 2008-03-27 16:16 Robert Byrnes * src/readelf.c (donote): ELF core file command name/line bug fixes and enhancements: Try larger offsets first to avoid false matches from earlier data that happen to look like strings; this primarily affected SunOS 5.x 32-bit Intel core files. Add support for command line (instead of just short name) for SunOS 5.x. Add information about NT_PSINFO for SunOS 5.x. Only trim whitespace from end of command line. 2007-02-11 01:36 Reuben Thomas * Change strength of ! from MULT to 0, as it matches almost anything (Reuben Thomas) * Debian fixes (Reuben Thomas) 2007-02-11 00:17 Reuben Thomas * Clarify UTF-8 BOM message (Reuben Thomas) * Add HTML comment to token list in names.h 2007-02-04 15:50 Christos Zoulas * Debian fixes (Reuben Thomas) 2007-02-04 11:31 Christos Zoulas * !:mime annotations in magic files (Reuben Thomas) 2007-01-29 15:35 Christos Zoulas * zero out utime/utimes structs (Gavin Atkinson) 2007-01-26 13:45 Christos Zoulas * reduce writable data from Diego "Flameeyes" Petten 2007-12-28 15:06 Christos Zoulas * strtof detection * remove bogus regex magic that could cause a DoS * better mismatch version message 2007-12-27 11:35 Christos Zoulas * bring back some fixes from OpenBSD * treat ELF dynamic objects as executables * fix gcc warnings 2007-12-01 19:55 Christos Zoulas * make sure we have zlib.h and libz to compile the builtin decompress code 2007-10-28 20:48 Christos Zoulas * float and double magic support (Behan Webster) 2007-10-28 20:48 Christos Zoulas * Convert fortran to a soft test (Reuben Thomas) 2007-10-23 5:25 Christos Zoulas * Add --with-filename, and --no-filename (Reuben Thomas) 2007-10-23 3:59 Christos Zoulas * Rest of the mime split (Reuben Thomas) * Make usage message generated from the flags so that they stay consistent (Reuben Thomas) 2007-10-20 3:06 Christos Zoulas * typo in comment, missing ifdef QUICK, remove unneeded code (Charles Longeau) 2007-10-17 3:33 Christos Zoulas * Fix problem printing -\012 in some entries * Separate magic type and encoding flags (Reuben Thomas) 2007-10-09 3:55 Christos Zoulas * configure fix for int64 and strndup (Reuben Thomas) 2007-09-26 4:45 Christos Zoulas * Add magic_descriptor() function. * Fix regression in elf reading code where the core name was not being printed. * Don't convert NUL's to spaces in {l,b}estring16 (Daniel Dawson) 2007-08-19 6:30 Christos Zoulas * Make mime format consistent so that it can be easily parsed: mimetype [charset=character-set] [encoding=encoding-mime-type] Remove spurious extra text from some MIME type printouts (mostly in is_tar). Fix one case where -i produced nothing at all (for a 1-byte file, which is now classed as application/octet-stream). Remove 7/8bit classifications, since they were arbitrary and not based on the file data. This work was done by Reuben Thomas 2007-05-24 10:00 Christos Zoulas * Fix another integer overflow (Colin Percival) 2007-03-26 13:58 Christos Zoulas * make sure that all of struct magic_set is initialized appropriately (Brett) 2007-03-25 17:44 Christos Zoulas * reset left bytes in the buffer (Dmitry V. Levin) * compilation failed with COMPILE_ONLY and ENABLE_CONDITIONALS (Peter Avalos) 2007-03-15 10:51 Christos Zoulas * fix fortran and nroff reversed tests (Dmitry V. Levin) * fix exclude option (Dmitry V. Levin) 2007-02-08 17:30 Christos Zoulas * fix integer underflow in file_printf which can lead to to exploitable heap overflow (Jean-Sebastien Guay-Lero) 2007-02-05 11:35 Christos Zoulas * make socket/pipe reading more robust 2007-01-25 16:01 Christos Zoulas * Centralize all the tests in file_buffer. * Add exclude flag. 2007-01-18 05:29 Anon Ymous * Move the "type" detection code from parse() into its own table driven routine. This avoids maintaining multiple lists in file.h. * Add an optional conditional field (ust before the type field). This code is wrapped in "#ifdef ENABLE_CONDITIONALS" as it is likely to go away. 2007-01-16 23:24 Anon Ymous * Fix an initialization bug in check_mem(). 2007-01-16 14:58 Anon Ymous * Add a "default" type to print a message if nothing previously matched at that level or since the last default at that level. This is useful for setting up switch-like statements. It can also be used to do if/else constructions without a redundant second test. * Fix the "x" special case test so that one can test for that string with "=x". * Allow "search" to search the entire buffer if the "/N" search count is missing. * Make "regex" work! It now starts its search at the specified offset and takes an (optional) "/N" line count to specify the search range; otherwise it searches to the end of the file. The match is now grabbed correctly for format strings and the offset set to the end of the match. * Add a "/s" flag to "regex" and "search" to set the offset to the start of the match. By default the offset is set to the end of the match, as it is with other tests. This is mostly useful for "regex". * Make "search", "string" and "pstring" use the same file_strncmp() routine so that they support the same flags; "bestring16" and "lestring16" call the same routine, but with flags = 0. Also add a "/C" flag (in analogy to "/c") to ignore the case on uppercase (lowercase) characters in the test string. * Strict adherence to C style string escapes. A warnings are printed when compiling. Note: previously "\a" was incorrectly translated to 'a' instead of an (i.e., BELL, typically 0x07). * Make this compile with "-Wall -Wextra" and all the warning flags used with WARNS=4 in the NetBSD source. Also make it pass lint. * Many "cleanups" and hopefully not too many new bugs! 2007-01-16 14:56 Anon Ymous * make several more files compile with gcc warnings on and also make them pass lint. 2007-01-16 14:54 Anon Ymous * fix a puts()/putc() usage goof in file.c * make file.c compile with gcc warnings and pass lint 2006-12-11 16:49 Christos Zoulas * fix byteswapping issue * report the number of bytes we tried to allocate when allocation fails * add a few missed cases in the strength routine 2006-12-08 16:32 Christos Zoulas * store and print the line number of the magic entry for debugging. * if the magic entry did not print anything, don't treat it as a match * change the magic strength algorithm to take into account the relationship op. * fix a bug in search where we could accidentally return a match. * propagate the error return from match to file_softmagic. 2006-11-25 13:35 Christos Zoulas * Don't store the current offset in the magic struct, because it needs to be restored and it was not done properly all the time. Bug found by: Arkadiusz Miskiewicz * Fix problem in the '\0' separator; and don't print it as an additional separator; print it as the only separator. 2006-11-17 10:51 Christos Zoulas * Added a -0 option to print a '\0' separator Etienne Buira 2006-10-31 15:14 Christos Zoulas * Check offset before copying (Mike Frysinger) * merge duplicated code * add quad date support * make sure that we nul terminate desc (Ryoji Kanai) * don't process elf notes multiple times * allow -z to report empty compressed files * use calloc to initialize the ascii buffers (Jos van den Oever) 2006-06-08 11:11 Christos Zoulas * QNX fixes (Mike Gorchak) * Add quad support. * FIFO checks (Dr. Werner Fink) * Linux ELF fixes (Dr. Werner Fink) * Magic format checks (Dr. Werner Fink) * Magic format function improvent (Karl Chen) 2006-05-03 11:11 Christos Zoulas * Pick up some elf changes and some constant fixes from SUSE * Identify gnu tar vs. posix tar * When keep going, don't print spurious newlines (Radek Vokal) 2006-04-01 12:02 Christos Zoulas * Use calloc instead of malloc (Mike Frysinger) * Fix configure script to detect wctypes.h (Mike Frysinger) 2006-03-02 16:06 Christos Zoulas * Print empty if the file is (Mike Frysinger) * Don't try to read past the end of the buffer (Mike Frysinger) * Sort magic entries by strength [experimental] 2005-11-29 13:26 Christos Zoulas * Use iswprint() to convert the output string. (Bastien Nocera) 2005-10-31 8:54 Christos Zoulas * Fix regression where the core info was not completely processed (Radek Vokal) 2005-10-20 11:15 Christos Zoulas * Middle Endian magic (Diomidis Spinellis) 2005-10-17 11:15 Christos Zoulas * Open with O_BINARY for CYGWIN (Corinna Vinschen) * Don't close stdin (Arkadiusz Miskiewicz) * Look for note sections in non executables. 2005-09-20 13:33 Christos Zoulas * Don't print SVR4 Style in core files multiple times (Radek Vokal) 2005-08-27 04:09 Christos Zoulas * Cygwin changes Corinna Vinschen 2005-08-18 09:53 Christos Zoulas * Remove erroreous mention of /etc/magic in the file man page This is gentoo bug 101639. (Mike Frysinger) * Cross-compile support and detection (Mike Frysinger) 2005-08-12 10:17 Christos Zoulas * Add -h flag and dereference symlinks if POSIXLY_CORRECT is set. 2005-07-29 13:57 Christos Zoulas * Avoid search and regex buffer overflows (Kelledin) 2005-07-12 11:48 Christos Zoulas * Provide stub implementations for {v,}nsprintf() for older OS's that don't have them. * Change mbstate_t autoconf detection macro from AC_MBSTATE_T to AC_TYPE_MBSTATE_T. 2005-06-25 11:48 Christos Zoulas * Dynamically allocate the string buffers and make the default read size 256K. 2005-06-01 00:00 Joerg Sonnenberger * Dragonfly ELF note support 2005-03-14 00:00 Giuliano Bertoletti * Avoid NULL pointer dereference in time conversion. 2005-03-06 00:00 Joerg Walter * Add indirect magic offset support, and search mode. 2005-01-12 00:00 Stepan Kasal * src/ascmagic.c (file_ascmagic): Fix three bugs about text files: If a CRLF text file happens to have CR at offset HOWMANY - 1 (currently 0xffff), it should not be counted as CR line terminator. If a line has length exactly MAXLINELEN, it should not yet be treated as a ``very long line'', as MAXLINELEN is ``longest sane line length''. With CRLF, the line length was not computed correctly, and even lines of length MAXLINELEN - 1 were treated as ``very long''. 2004-12-07 14:15 Christos Zoulas * bzip2 needs a lot of input buffer space on some files before it can begin uncompressing. This makes file -z fail on some bz2 files. Fix it by giving it a copy of the file descriptor to read as much as it wants if we have access to it. 2004-11-24 12:39 Christos Zoulas * Stack smash fix, and ELF more conservative reading.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped. The main things grep needs to know about mmap are: * does it exist and is it safe to write into the mmap'd area * how to use it (BSD variants) */ #include #include #if !defined STDC_HEADERS && !defined HAVE_STDLIB_H char *malloc (); #endif /* This mess was copied from the GNU getpagesize.h. */ #ifndef HAVE_GETPAGESIZE # ifdef _SC_PAGESIZE # define getpagesize() sysconf(_SC_PAGESIZE) # else /* no _SC_PAGESIZE */ # ifdef HAVE_SYS_PARAM_H # include # ifdef EXEC_PAGESIZE # define getpagesize() EXEC_PAGESIZE # else /* no EXEC_PAGESIZE */ # ifdef NBPG # define getpagesize() NBPG * CLSIZE # ifndef CLSIZE # define CLSIZE 1 # endif /* no CLSIZE */ # else /* no NBPG */ # ifdef NBPC # define getpagesize() NBPC # else /* no NBPC */ # ifdef PAGESIZE # define getpagesize() PAGESIZE # endif /* PAGESIZE */ # endif /* no NBPC */ # endif /* no NBPG */ # endif /* no EXEC_PAGESIZE */ # else /* no HAVE_SYS_PARAM_H */ # define getpagesize() 8192 /* punt totally */ # endif /* no HAVE_SYS_PARAM_H */ # endif /* no _SC_PAGESIZE */ #endif /* no HAVE_GETPAGESIZE */ int main () { char *data, *data2, *data3; const char *cdata2; int i, pagesize; int fd, fd2; pagesize = getpagesize (); /* First, make a file with some known garbage in it. */ data = (char *) malloc (pagesize); if (!data) return 1; for (i = 0; i < pagesize; ++i) *(data + i) = rand (); umask (0); fd = creat ("conftest.mmap", 0600); if (fd < 0) return 2; if (write (fd, data, pagesize) != pagesize) return 3; close (fd); /* Next, check that the tail of a page is zero-filled.

There are three sets of tests, performed in this order: filesystem tests, magic tests, and language tests. The .Em first test that succeeds causes the file type to be printed. .Pp The type printed will usually contain one of the words .Em text (the file contains only printing characters and a few common control characters and is probably safe to read on an .Dv ASCII terminal), .Em executable (the file contains the result of compiling a program in a form understandable to some .Tn UNIX kernel or another), or .Em data meaning anything else (data is usually .Dq binary or non-printable). Exceptions are well-known file formats (core files, tar archives) that are known to contain binary data. When modifying magic files or the program itself, make sure to .Em "preserve these keywords" . Users depend on knowing that all the readable files in a directory have the word .Dq text printed. Don't do as Berkeley did and change .Dq shell commands text to .Dq shell script . .Pp The filesystem tests are based on examining the return from a .Xr stat 2 system call. The program checks to see if the file is empty, or if it's some sort of special file. Any known file types appropriate to the system you are running on (sockets, symbolic links, or named pipes (FIFOs) on those systems that implement them) are intuited if they are defined in the system header file .In sys/stat.h . .Pp The magic tests are used to check for files with data in particular fixed formats. The canonical example of this is a binary executable (compiled program) .Dv a.out file, whose format is defined in .In elf.h , .In a.out.h and possibly .In exec.h in the standard include directory. These files have a .Dq "magic number" stored in a particular place near the beginning of the file that tells the .Tn UNIX operating system that the file is a binary executable, and which of several types thereof. The concept of a .Dq "magic" has been applied by extension to data files. Any file with some invariant identifier at a small fixed offset into the file can usually be described in this way. The information identifying these files is read from the compiled magic file .Pa __MAGIC__.mgc , or the files in the directory .Pa __MAGIC__ if the compiled file does not exist. In addition, if .Pa $HOME/.magic.mgc or .Pa $HOME/.magic exists, it will be used in preference to the system magic files. .Pp If a file does not match any of the entries in the magic file, it is examined to see if it seems to be a text file. ASCII, ISO-8859-x, non-ISO 8-bit extended-ASCII character sets (such as those used on Macintosh and IBM PC systems), UTF-8-encoded Unicode, UTF-16-encoded Unicode, and EBCDIC character sets can be distinguished by the different ranges and sequences of bytes that constitute printable text in each set. If a file passes any of these tests, its character set is reported. ASCII, ISO-8859-x, UTF-8, and extended-ASCII files are identified as .Dq text because they will be mostly readable on nearly any terminal; UTF-16 and EBCDIC are only .Dq character data because, while they contain text, it is text that will require translation before it can be read. In addition, .Nm will attempt to determine other characteristics of text-type files. If the lines of a file are terminated by CR, CRLF, or NEL, instead of the Unix-standard LF, this will be reported. Files that contain embedded escape sequences or overstriking will also be identified. .Pp Once .Nm has determined the character set used in a text-type file, it will attempt to determine in what language the file is written. The language tests look for particular strings (cf. .In names.h ) that can appear anywhere in the first few blocks of a file. For example, the keyword .Em .br indicates that the file is most likely a .Xr troff 1 input file, just as the keyword .Em struct indicates a C program. These tests are less reliable than the previous two groups, so they are performed last. The language test routines also test for some miscellany (such as .Xr tar 1 archives). .Pp Any file that cannot be identified as having been written in any of the character sets listed above is simply said to be .Dq data . .Sh OPTIONS .Bl -tag -width indent .It Fl Fl apple Causes the file command to output the file type and creator code as used by older MacOS versions. The code consists of eight letters, the first describing the file type, the latter the creator. .It Fl b , Fl Fl brief Do not prepend filenames to output lines (brief mode). .It Fl C , Fl Fl compile Write a .Pa magic.mgc output file that contains a pre-parsed version of the magic file or directory. .It Fl c , Fl Fl checking-printout Cause a checking printout of the parsed form of the magic file. This is usually used in conjunction with the .Fl m flag to debug a new magic file before installing it. .It Fl E On filesystem errors (file not found etc), instead of handling the error as regular output as POSIX mandates and keep going, issue an error message and exit. .It Fl e , Fl Fl exclude Ar testname Exclude the test named in .Ar testname from the list of tests made to determine the file type. Valid test names are: .Bl -tag -width compress .It apptype .Dv EMX application type (only on EMX). .It ascii Various types of text files (this test will try to guess the text encoding, irrespective of the setting of the .Sq encoding option). .It encoding Different text encodings for soft magic tests. .It tokens Ignored for backwards compatibility. .It cdf Prints details of Compound Document Files. .It compress Checks for, and looks inside, compressed files. .It elf Prints ELF file details. .It soft Consults magic files. .It tar Examines tar files. .El .It Fl Fl extension Print a slash-separated list of valid extensions for the file type found. .It Fl F , Fl Fl separator Ar separator Use the specified string as the separator between the filename and the file result returned. Defaults to .Sq \&: . .It Fl f , Fl Fl files-from Ar namefile Read the names of the files to be examined from .Ar namefile (one per line) before the argument list. Either .Ar namefile or at least one filename argument must be present; to test the standard input, use .Sq - as a filename argument. Please note that .Ar namefile is unwrapped and the enclosed filenames are processed when this option is encountered and before any further options processing is done. This allows one to process multiple lists of files with different command line arguments on the same .Nm invocation. Thus if you want to set the delimiter, you need to do it before you specify the list of files, like: .Dq Fl F Ar @ Fl f Ar namefile , instead of: .Dq Fl f Ar namefile Fl F Ar @ . .It Fl h , Fl Fl no-dereference option causes symlinks not to be followed (on systems that support symbolic links). This is the default if the environment variable .Dv POSIXLY_CORRECT is not defined. .It Fl i , Fl Fl mime Causes the file command to output mime type strings rather than the more traditional human readable ones. Thus it may say .Sq text/plain; charset=us-ascii rather than .Dq ASCII text . .It Fl Fl mime-type , Fl Fl mime-encoding Like .Fl i , but print only the specified element(s). .It Fl k , Fl Fl keep-going Don't stop at the first match, keep going. Subsequent matches will be have the string .Sq "\[rs]012\- " prepended. (If you want a newline, see the .Fl r option.) The magic pattern with the highest strength (see the .Fl l option) comes first. .It Fl l , Fl Fl list Shows a list of patterns and their strength sorted descending by .Xr magic 4 strength which is used for the matching (see also the .Fl k option). .It Fl L , Fl Fl dereference option causes symlinks to be followed, as the like-named option in .Xr ls 1 (on systems that support symbolic links). This is the default if the environment variable .Ev POSIXLY_CORRECT is defined. .It Fl m , Fl Fl magic-file Ar magicfiles Specify an alternate list of files and directories containing magic. This can be a single item, or a colon-separated list. If a compiled magic file is found alongside a file or directory, it will be used instead. .It Fl N , Fl Fl no-pad Don't pad filenames so that they align in the output. .It Fl n , Fl Fl no-buffer Force stdout to be flushed after checking each file. This is only useful if checking a list of files. It is intended to be used by programs that want filetype output from a pipe. .It Fl p , Fl Fl preserve-date On systems that support .Xr utime 3 or .Xr utimes 2 , attempt to preserve the access time of files analyzed, to pretend that .Nm never read them. .It Fl P , Fl Fl parameter Ar name=value Set various parameter limits. .Bl -column "elf_phnum" "Default" "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" -offset indent .It Sy "Name" Ta Sy "Default" Ta Sy "Explanation" .It Li indir Ta 15 Ta recursion limit for indirect magic .It Li name Ta 30 Ta use count limit for name/use magic .It Li elf_notes Ta 256 Ta max ELF notes processed .It Li elf_phnum Ta 128 Ta max ELF program sections processed .It Li elf_shnum Ta 32768 Ta max ELF sections processed +.It Li regex Ta 8192 Ta length limit for regex searches .El .It Fl r , Fl Fl raw Don't translate unprintable characters to \eooo. Normally .Nm translates unprintable characters to their octal representation. .It Fl s , Fl Fl special-files Normally, .Nm only attempts to read and determine the type of argument files which .Xr stat 2 reports are ordinary files. This prevents problems, because reading special files may have peculiar consequences. Specifying the .Fl s option causes .Nm to also read argument files which are block or character special files. This is useful for determining the filesystem types of the data in raw disk partitions, which are block special files. This option also causes .Nm to disregard the file size as reported by .Xr stat 2 since on some systems it reports a zero size for raw disk partitions. .It Fl v , Fl Fl version Print the version of the program and exit. .It Fl z , Fl Fl uncompress Try to look inside compressed files. .It Fl Z , Fl Fl uncompress-noreport Try to look inside compressed files, but report information about the contents only not the compression. .It Fl 0 , Fl Fl print0 Output a null character .Sq \e0 after the end of the filename. Nice to .Xr cut 1 the output. This does not affect the separator, which is still printed. .It Fl -help Print a help message and exit. .El .Sh FILES .Bl -tag -width __MAGIC__.mgc -compact .It Pa __MAGIC__.mgc Default compiled list of magic. .It Pa __MAGIC__ Directory containing default magic files. .El .Sh ENVIRONMENT The environment variable .Ev MAGIC can be used to set the default magic file name. If that variable is set, then .Nm will not attempt to open .Pa $HOME/.magic . .Nm adds .Dq Pa .mgc to the value of this variable as appropriate. However, .Pa file has to exist in order for .Pa file.mime to be considered. The environment variable .Ev POSIXLY_CORRECT controls (on systems that support symbolic links), whether .Nm will attempt to follow symlinks or not. If set, then .Nm follows symlink, otherwise it does not. This is also controlled by the .Fl L and .Fl h options. .Sh SEE ALSO .Xr magic __FSECTION__ , .Xr hexdump 1 , .Xr od 1 , .Xr strings 1 , .Xr fstyp 8 .Sh STANDARDS CONFORMANCE This program is believed to exceed the System V Interface Definition of FILE(CMD), as near as one can determine from the vague language contained therein. Its behavior is mostly compatible with the System V program of the same name. This version knows more magic, however, so it will produce different (albeit more accurate) output in many cases. .\" URL: http://www.opengroup.org/onlinepubs/009695399/utilities/file.html .Pp The one significant difference between this version and System V is that this version treats any white space as a delimiter, so that spaces in pattern strings must be escaped. For example, .Bd -literal -offset indent \*[Gt]10 string language impress\ (imPRESS data) .Ed .Pp in an existing magic file would have to be changed to .Bd -literal -offset indent \*[Gt]10 string language\e impress (imPRESS data) .Ed .Pp In addition, in this version, if a pattern string contains a backslash, it must be escaped. For example .Bd -literal -offset indent 0 string \ebegindata Andrew Toolkit document .Ed .Pp in an existing magic file would have to be changed to .Bd -literal -offset indent 0 string \e\ebegindata Andrew Toolkit document .Ed .Pp SunOS releases 3.2 and later from Sun Microsystems include a .Nm command derived from the System V one, but with some extensions. This version differs from Sun's only in minor ways. It includes the extension of the .Sq \*[Am] operator, used as, for example, .Bd -literal -offset indent \*[Gt]16 long\*[Am]0x7fffffff \*[Gt]0 not stripped .Ed .Sh MAGIC DIRECTORY The magic file entries have been collected from various sources, mainly USENET, and contributed by various authors. Christos Zoulas (address below) will collect additional or corrected magic file entries. A consolidation of magic file entries will be distributed periodically. .Pp The order of entries in the magic file is significant. Depending on what system you are using, the order that they are put together may be incorrect. If your old .Nm command uses a magic file, keep the old magic file around for comparison purposes (rename it to .Pa __MAGIC__.orig ) . .Sh EXAMPLES .Bd -literal -offset indent $ file file.c file /dev/{wd0a,hda} file.c: C program text file: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped /dev/wd0a: block special (0/0) /dev/hda: block special (3/0) $ file -s /dev/wd0{b,d} /dev/wd0b: data /dev/wd0d: x86 boot sector $ file -s /dev/hda{,1,2,3,4,5,6,7,8,9,10} /dev/hda: x86 boot sector /dev/hda1: Linux/i386 ext2 filesystem /dev/hda2: x86 boot sector /dev/hda3: x86 boot sector, extended partition table /dev/hda4: Linux/i386 ext2 filesystem /dev/hda5: Linux/i386 swap file /dev/hda6: Linux/i386 swap file /dev/hda7: Linux/i386 swap file /dev/hda8: Linux/i386 swap file /dev/hda9: empty /dev/hda10: empty $ file -i file.c file /dev/{wd0a,hda} file.c: text/x-c file: application/x-executable /dev/hda: application/x-not-regular-file /dev/wd0a: application/x-not-regular-file .Ed .Sh HISTORY There has been a .Nm command in every .Dv UNIX since at least Research Version 4 (man page dated November, 1973). The System V version introduced one significant major change: the external list of magic types. This slowed the program down slightly but made it a lot more flexible. .Pp This program, based on the System V version, was written by Ian Darwin .Aq ian@darwinsys.com without looking at anybody else's source code. .Pp John Gilmore revised the code extensively, making it better than the first version. Geoff Collyer found several inadequacies and provided some magic file entries. Contributions by the .Sq \*[Am] operator by Rob McMahon, .Aq cudcv@warwick.ac.uk , 1989. .Pp Guy Harris, .Aq guy@netapp.com , made many changes from 1993 to the present. 1989. .Pp Primary development and maintenance from 1990 to the present by Christos Zoulas .Aq christos@astron.com . .Pp Altered by Chris Lowth .Aq chris@lowth.com , 2000: handle the .Fl i option to output mime type strings, using an alternative magic file and internal logic. .Pp Altered by Eric Fischer .Aq enf@pobox.com , July, 2000, to identify character codes and attempt to identify the languages of non-ASCII files. .Pp Altered by Reuben Thomas .Aq rrt@sc3d.org , 2007-2011, to improve MIME support, merge MIME and non-MIME magic, support directories as well as files of magic, apply many bug fixes, update and fix a lot of magic, improve the build system, improve the documentation, and rewrite the Python bindings in pure Python. .Pp The list of contributors to the .Sq magic directory (magic files) is too long to include here. You know who you are; thank you. Many contributors are listed in the source files. .Sh LEGAL NOTICE Copyright (c) Ian F. Darwin, Toronto, Canada, 1986-1999.

This needs a design. Suggestion: push possible outputs on to a list, then pick the last-pushed (most specific, one hopes) value at the end, or use a default if the list is empty. This should not slow down evaluation. .Pp The handling of .Dv MAGIC_CONTINUE and printing \e012- between entries is clumsy and complicated; refactor and centralize. .Pp Some of the encoding logic is hard-coded in encoding.c and can be moved to the magic files if we had a !:charset annotation .Pp Continue to squash all magic bugs. See Debian BTS for a good source. .Pp Store arbitrarily long strings, for example for %s patterns, so that they can be printed out. Fixes Debian bug #271672. This can be done by allocating strings in a string pool, storing the string pool at the end of the magic file and converting all the string pointers to relative offsets from the string pool. .Pp Add syntax for relative offsets after current level (Debian bug #466037). .Pp Make file -ki work, i.e. give multiple MIME types. .Pp Add a zip library so we can peek inside Office2007 documents to print more details about their contents. .Pp Add an option to print URLs for the sources of the file descriptions. .Pp Combine script searches and add a way to map executable names to MIME types (e.g. have a magic value for !:mime which causes the resulting string to be looked up in a table). This would avoid adding the same magic repeatedly for each new hash-bang interpreter. .Pp When a file descriptor is available, we can skip and adjust the buffer instead of the hacky buffer management we do now. .Pp Fix .Dq name and .Dq use to check for consistency at compile time (duplicate .Dq name , .Dq use pointing to undefined .Dq name ). Make .Dq name / .Dq use more efficient by keeping a sorted list of names. Special-case ^ to flip endianness in the parser so that it does not have to be escaped, and document it. .Pp If the offsets specified internally in the file exceed the buffer size ( .Dv HOWMANY variable in file.h), then we don't seek to that offset, but we give up. It would be better if buffer managements was done when the file descriptor is available so move around the file. One must be careful though because this has performance (and thus security considerations). .Sh AVAILABILITY You can obtain the original author's latest version by anonymous FTP on .Pa ftp.astron.com in the directory .Pa /pub/file/file-X.YZ.tar.gz .

It returns .Dv NULL if there was an error allocating the magic cookie. The .Ar flags argument specifies how the other magic functions should behave: .Bl -tag -width MAGIC_COMPRESS .It Dv MAGIC_NONE No special handling. .It Dv MAGIC_DEBUG Print debugging messages to stderr. .It Dv MAGIC_SYMLINK If the file queried is a symlink, follow it. .It Dv MAGIC_COMPRESS If the file is compressed, unpack it and look at the contents. .It Dv MAGIC_DEVICES If the file is a block or character special device, then open the device and try to look in its contents. .It Dv MAGIC_MIME_TYPE Return a MIME type string, instead of a textual description. .It Dv MAGIC_MIME_ENCODING Return a MIME encoding, instead of a textual description. .It Dv MAGIC_MIME A shorthand for MAGIC_MIME_TYPE | MAGIC_MIME_ENCODING. .It Dv MAGIC_CONTINUE Return all matches, not just the first. .It Dv MAGIC_CHECK Check the magic database for consistency and print warnings to stderr. .It Dv MAGIC_PRESERVE_ATIME On systems that support .Xr utime 3 or .Xr utimes 2 , attempt to preserve the access time of files analysed. .It Dv MAGIC_RAW Don't translate unprintable characters to a \eooo octal representation. .It Dv MAGIC_ERROR Treat operating system errors while trying to open files and follow symlinks as real errors, instead of printing them in the magic buffer. .It Dv MAGIC_APPLE Return the Apple creator and type. .It Dv MAGIC_EXTENSION Return a slash-separated list of extensions for this file type. .It Dv MAGIC_COMPRESS_TRANSP Don't report on compression, only report about the uncompressed data. .It Dv MAGIC_NO_CHECK_APPTYPE Don't check for .Dv EMX application type (only on EMX). .It Dv MAGIC_NO_CHECK_CDF Don't get extra information on MS Composite Document Files. .It Dv MAGIC_NO_CHECK_COMPRESS Don't look inside compressed files. .It Dv MAGIC_NO_CHECK_ELF Don't print ELF details. .It Dv MAGIC_NO_CHECK_ENCODING Don't check text encodings. .It Dv MAGIC_NO_CHECK_SOFT Don't consult magic files. .It Dv MAGIC_NO_CHECK_TAR Don't examine tar files. .It Dv MAGIC_NO_CHECK_TEXT Don't check for various types of text files. .It Dv MAGIC_NO_CHECK_TOKENS Don't look for known tokens inside ascii files. .El .Pp The .Fn magic_close function closes the .Xr magic __FSECTION__ database and deallocates any resources used. .Pp The .Fn magic_error function returns a textual explanation of the last error, or .Dv NULL if there was no error. .Pp The .Fn magic_errno function returns the last operating system error number .Pq Xr errno 2 that was encountered by a system call. .Pp The .Fn magic_file function returns a textual description of the contents of the .Ar filename argument, or .Dv NULL if an error occurred. If the .Ar filename is .Dv NULL , then stdin is used. .Pp The .Fn magic_descriptor function returns a textual description of the contents of the .Ar fd argument, or .Dv NULL if an error occurred. .Pp The .Fn magic_buffer function returns a textual description of the contents of the .Ar buffer argument with .Ar length bytes size. .Pp The .Fn magic_setflags function sets the .Ar flags described above. Note that using both MIME flags together can also return extra information on the charset. .Pp The .Fn magic_check function can be used to check the validity of entries in the colon separated database files passed in as .Ar filename , or .Dv NULL for the default database. It returns 0 on success and \-1 on failure. .Pp The .Fn magic_compile function can be used to compile the the colon separated list of database files passed in as .Ar filename , or .Dv NULL for the default database. It returns 0 on success and \-1 on failure. The compiled files created are named from the .Xr basename 1 of each file argument with .Dq .mgc appended to it. .Pp The .Fn magic_list function dumps all magic entries in a human readable format, dumping first the entries that are matched against binary files and then the ones that match text files. It takes and optional .Fa filename argument which is a colon separated list of database files, or .Dv NULL for the default database. .Pp The .Fn magic_load function must be used to load the the colon separated list of database files passed in as .Ar filename , or .Dv NULL for the default database file before any magic queries can performed. .Pp The default database file is named by the MAGIC environment variable. If that variable is not set, the default database file name is __MAGIC__. .Fn magic_load adds .Dq .mgc to the database filename as appropriate. .Pp The .Fn magic_load_buffers function takes an array of size .Fa nbuffers of .Fa buffers with a respective size for each in the array of .Fa sizes loaded with the contents of the magic databases from the filesystem. This function can be used in environment where the magic library does not have direct access to the filesystem, but can access the magic database via shared memory or other IPC means. .Pp The .Fn magic_getparam and .Fn magic_setparam allow getting and setting various limits related to the the magic library. .Bl -column "MAGIC_PARAM_ELF_PHNUM_MAX" "size_t" "Default" -offset indent .It Sy "Parameter" Ta Sy "Type" Ta Sy "Default" .It Li MAGIC_PARAM_INDIR_MAX Ta size_t Ta 15 .It Li MAGIC_PARAM_NAME_MAX Ta size_t Ta 30 .It Li MAGIC_PARAM_ELF_NOTES_MAX Ta size_t Ta 256 .It Li MAGIC_PARAM_ELF_PHNUM_MAX Ta size_t Ta 128 .It Li MAGIC_PARAM_ELF_SHNUM_MAX Ta size_t Ta 32768 +.It Li MAGIC_PARAM_REGEX_MAX Ta size_t Ta 8192 .El .Pp The .Dv MAGIC_PARAM_INDIR_RECURSION parameter controls how many levels of recursion will be followed for indirect magic entries. .Pp The .Dv MAGIC_PARAM_NAME_RECURSION parameter controls how many levels of recursion will be followed for for name/use calls. .Pp The .Dv MAGIC_PARAM_NAME_MAX parameter controls the maximum number of calls for name/use. .Pp The .Dv MAGIC_PARAM_NOTES_MAX parameter controls how many ELF notes will be processed. .Pp The .Dv MAGIC_PARAM_PHNUM_MAX parameter controls how many ELF program sections will be processed. .Pp The .Dv MAGIC_PARAM_SHNUM_MAX parameter controls how many ELF sections will be processed. .Pp The .Fn magic_version command returns the version number of this library which is compiled into the shared library using the constant .Dv MAGIC_VERSION from .In magic.h . This can be used by client programs to verify that the version they compile against is the same as the version that they run against. .Sh RETURN VALUES The function .Fn magic_open returns a magic cookie on success and .Dv NULL on failure setting errno to an appropriate value. It will set errno to .Er EINVAL if an unsupported value for flags was given. The .Fn magic_list , .Fn magic_load , .Fn magic_compile , and .Fn magic_check functions return 0 on success and \-1 on failure. The .Fn magic_buffer , .Fn magic_getpath , and .Fn magic_file , functions return a string on success and .Dv NULL on failure. The .Fn magic_error function returns a textual description of the errors of the above functions, or .Dv NULL if there was no error. The .Fn magic_version always returns the version number of the library. Finally, .Fn magic_setflags returns \-1 on systems that don't support .Xr utime 3 , or .Xr utimes 2 when .Dv MAGIC_PRESERVE_ATIME is set. .Sh FILES .Bl -tag -width __MAGIC__.mgc -compact .It Pa __MAGIC__ The non-compiled default magic database. .It Pa __MAGIC__.mgc The compiled default magic database. .El .Sh SEE ALSO .Xr file __CSECTION__ , .Xr magic __FSECTION__ .Sh AUTHORS .An M\(oans Rullg\(oard Initial libmagic implementation, and configuration. .An Christos Zoulas API cleanup, error code and allocation handling.

The .Xr file __CSECTION__ command identifies the type of a file using, among other tests, a test for whether the file contains certain .Dq "magic patterns" . The file .Pa __MAGIC__ specifies what patterns are to be tested for, what message or MIME type to print if a particular pattern is found, and additional information to extract from the file. .Pp Each line of the file specifies a test to be performed. A test compares the data starting at a particular offset in the file with a byte value, a string or a numeric value. If the test succeeds, a message is printed. The line consists of the following fields: .Bl -tag -width ".Dv message" .It Dv offset A number specifying the offset, in bytes, into the file of the data which is to be tested. .It Dv type The type of the data to be tested. The possible values are: .Bl -tag -width ".Dv lestring16" .It Dv byte A one-byte value. .It Dv short A two-byte value in this machine's native byte order. .It Dv long A four-byte value in this machine's native byte order. .It Dv quad An eight-byte value in this machine's native byte order. .It Dv float A 32-bit single precision IEEE floating point number in this machine's native byte order. .It Dv double A 64-bit double precision IEEE floating point number in this machine's native byte order. .It Dv string A string of bytes. The string type specification can be optionally followed by /[WwcCtbT]*. The .Dq W flag compacts whitespace in the target, which must contain at least one whitespace character. If the magic has .Dv n consecutive blanks, the target needs at least .Dv n consecutive blanks to match. The .Dq w flag treats every blank in the magic as an optional blank. The .Dq c flag specifies case insensitive matching: lower case characters in the magic match both lower and upper case characters in the target, whereas upper case characters in the magic only match upper case characters in the target. The .Dq C flag specifies case insensitive matching: upper case characters in the magic match both lower and upper case characters in the target, whereas lower case characters in the magic only match upper case characters in the target. To do a complete case insensitive match, specify both .Dq c and .Dq C . The .Dq t flag forces the test to be done for text files, while the .Dq b flag forces the test to be done for binary files. The .Dq T flag causes the string to be trimmed, i.e. leading and trailing whitespace is deleted before the string is printed. .It Dv pstring A Pascal-style string where the first byte/short/int is interpreted as the unsigned length. The length defaults to byte and can be specified as a modifier. The following modifiers are supported: .Bl -tag -compact -width B .It B A byte length (default). .It H A 2 byte big endian length. .It h A 2 byte big little length. .It L A 4 byte big endian length. .It l A 4 byte big little length. .It J The length includes itself in its count. .El The string is not NUL terminated. .Dq J is used rather than the more valuable .Dq I because this type of length is a feature of the JPEG format. .It Dv date A four-byte value interpreted as a UNIX date. .It Dv qdate A eight-byte value interpreted as a UNIX date. .It Dv ldate A four-byte value interpreted as a UNIX-style date, but interpreted as local time rather than UTC. .It Dv qldate An eight-byte value interpreted as a UNIX-style date, but interpreted as local time rather than UTC. .It Dv qwdate An eight-byte value interpreted as a Windows-style date. .It Dv beid3 A 32-bit ID3 length in big-endian byte order. .It Dv beshort A two-byte value in big-endian byte order. .It Dv belong A four-byte value in big-endian byte order. .It Dv bequad An eight-byte value in big-endian byte order. .It Dv befloat A 32-bit single precision IEEE floating point number in big-endian byte order. .It Dv bedouble A 64-bit double precision IEEE floating point number in big-endian byte order. .It Dv bedate A four-byte value in big-endian byte order, interpreted as a Unix date. .It Dv beqdate An eight-byte value in big-endian byte order, interpreted as a Unix date. .It Dv beldate A four-byte value in big-endian byte order, interpreted as a UNIX-style date, but interpreted as local time rather than UTC. .It Dv beqldate An eight-byte value in big-endian byte order, interpreted as a UNIX-style date, but interpreted as local time rather than UTC. .It Dv beqwdate An eight-byte value in big-endian byte order, interpreted as a Windows-style date. .It Dv bestring16 A two-byte unicode (UCS16) string in big-endian byte order. .It Dv leid3 A 32-bit ID3 length in little-endian byte order. .It Dv leshort A two-byte value in little-endian byte order. .It Dv lelong A four-byte value in little-endian byte order. .It Dv lequad An eight-byte value in little-endian byte order. .It Dv lefloat A 32-bit single precision IEEE floating point number in little-endian byte order. .It Dv ledouble A 64-bit double precision IEEE floating point number in little-endian byte order. .It Dv ledate A four-byte value in little-endian byte order, interpreted as a UNIX date. .It Dv leqdate An eight-byte value in little-endian byte order, interpreted as a UNIX date. .It Dv leldate A four-byte value in little-endian byte order, interpreted as a UNIX-style date, but interpreted as local time rather than UTC. .It Dv leqldate An eight-byte value in little-endian byte order, interpreted as a UNIX-style date, but interpreted as local time rather than UTC. .It Dv leqwdate An eight-byte value in little-endian byte order, interpreted as a Windows-style date. .It Dv lestring16 A two-byte unicode (UCS16) string in little-endian byte order. .It Dv melong A four-byte value in middle-endian (PDP-11) byte order. .It Dv medate A four-byte value in middle-endian (PDP-11) byte order, interpreted as a UNIX date. .It Dv meldate A four-byte value in middle-endian (PDP-11) byte order, interpreted as a UNIX-style date, but interpreted as local time rather than UTC. .It Dv indirect Starting at the given offset, consult the magic database again. -The offset of th +The offset of the .Dv indirect magic is by default absolute in the file, but one can specify .Dv /r to indicate that the offset is relative from the beginning of the entry. .It Dv name Define a .Dq named magic instance that can be called from another .Dv use magic entry, like a subroutine call. Named instance direct magic offsets are relative to the offset of the previous matched entry, but indirect offsets are relative to the beginning of the file as usual. Named magic entries always match. .It Dv use Recursively call the named magic starting from the current offset. If the name of the referenced begins with a .Dv ^ then the endianness of the magic is switched; if the magic mentioned .Dv leshort for example, it is treated as .Dv beshort and vice versa. This is useful to avoid duplicating the rules for different endianness. .It Dv regex A regular expression match in extended POSIX regular expression syntax (like egrep). Regular expressions can take exponential time to process, and their performance is hard to predict, so their use is discouraged. When used in production environments, their performance should be carefully checked. The size of the string to search should also be limited by specifying .Dv / , to avoid performance issues scanning long files. The type specification can also be optionally followed by .Dv /[c][s][l] . The .Dq c flag makes the match case insensitive, while the .Dq s flag update the offset to the start offset of the match, rather than the end. The .Dq l modifier, changes the limit of length to mean number of lines instead of a byte count. Lines are delimited by the platforms native line delimiter. When a line count is specified, an implicit byte count also computed assuming each line is 80 characters long. If neither a byte or line count is specified, the search is limited automatically to 8KiB. .Dv ^ and .Dv $ match the beginning and end of individual lines, respectively, not beginning and end of file. .It Dv search A literal string search starting at the given offset. The same modifier flags can be used as for string patterns. The search expression must contain the range in the form .Dv /number, that is the number of positions at which the match will be attempted, starting from the start offset. This is suitable for searching larger binary expressions with variable offsets, using .Dv \e escapes for special characters. The order of modifier and number is not relevant. .It Dv default This is intended to be used with the test .Em x (which is always true) and it has no type. It matches when no other test at that continuation level has matched before. Clearing that matched tests for a continuation level, can be done using the .Dv clear test. .It Dv clear This test is always true and clears the match flag for that continuation level. It is intended to be used with the .Dv default test. .El .Pp For compatibility with the Single .Ux Standard, the type specifiers .Dv dC and .Dv d1 are equivalent to .Dv byte , the type specifiers .Dv uC and .Dv u1 are equivalent to .Dv ubyte , the type specifiers .Dv dS and .Dv d2 are equivalent to .Dv short , the type specifiers .Dv uS and .Dv u2 are equivalent to .Dv ushort , the type specifiers .Dv dI , .Dv dL , and .Dv d4 are equivalent to .Dv long , the type specifiers .Dv uI , .Dv uL , and .Dv u4 are equivalent to .Dv ulong , the type specifier .Dv d8 is equivalent to .Dv quad , the type specifier .Dv u8 is equivalent to .Dv uquad , and the type specifier .Dv s is equivalent to .Dv string . In addition, the type specifier .Dv dQ is equivalent to .Dv quad and the type specifier .Dv uQ is equivalent to .Dv uquad . .Pp Each top-level magic pattern (see below for an explanation of levels) is classified as text or binary according to the types used. Types .Dq regex and .Dq search are classified as text tests, unless non-printable characters are used in the pattern. All other tests are classified as binary. A top-level pattern is considered to be a test text when all its patterns are text patterns; otherwise, it is considered to be a binary pattern. When matching a file, binary patterns are tried first; if no match is found, and the file looks like text, then its encoding is determined and the text patterns are tried. .Pp The numeric types may optionally be followed by .Dv \*[Am] and a numeric value, to specify that the value is to be AND'ed with the numeric value before any comparisons are done. Prepending a .Dv u to the type indicates that ordered comparisons should be unsigned. .It Dv test The value to be compared with the value from the file. If the type is numeric, this value is specified in C form; if it is a string, it is specified as a C string with the usual escapes permitted (e.g. \en for new-line). .Pp Numeric values may be preceded by a character indicating the operation to be performed. It may be .Dv = , to specify that the value from the file must equal the specified value, .Dv \*[Lt] , to specify that the value from the file must be less than the specified value, .Dv \*[Gt] , to specify that the value from the file must be greater than the specified value, .Dv \*[Am] , to specify that the value from the file must have set all of the bits that are set in the specified value, .Dv ^ , to specify that the value from the file must have clear any of the bits that are set in the specified value, or .Dv ~ , the value specified after is negated before tested. .Dv x , to specify that any value will match. If the character is omitted, it is assumed to be .Dv = . Operators .Dv \*[Am] , .Dv ^ , and .Dv ~ don't work with floats and doubles. The operator .Dv !\& specifies that the line matches if the test does .Em not succeed. .Pp Numeric values are specified in C form; e.g. .Dv 13 is decimal, .Dv 013 is octal, and .Dv 0x13 is hexadecimal. .Pp Numeric operations are not performed on date types, instead the numeric value is interpreted as an offset. .Pp For string values, the string from the file must match the specified string. The operators .Dv = , .Dv \*[Lt] and .Dv \*[Gt] (but not .Dv \*[Am] ) can be applied to strings. The length used for matching is that of the string argument in the magic file. This means that a line can match any non-empty string (usually used to then print the string), with .Em \*[Gt]\e0 (because all non-empty strings are greater than the empty string). .Pp Dates are treated as numerical values in the respective internal representation. .Pp The special test .Em x always evaluates to true. .It Dv message The message to be printed if the comparison succeeds. If the string contains a .Xr printf 3 format specification, the value from the file (with any specified masking performed) is printed using the message as the format string. If the string begins with .Dq \eb , the message printed is the remainder of the string with no whitespace added before it: multiple matches are normally separated by a single space. .El .Pp An APPLE 4+4 character APPLE creator and type can be specified as: .Bd -literal -offset indent !:apple CREATYPE .Ed .Pp A MIME type is given on a separate line, which must be the next non-blank or comment line after the magic line that identifies the file type, and has the following format: .Bd -literal -offset indent !:mime MIMETYPE .Ed .Pp i.e. the literal string .Dq !:mime followed by the MIME type. .Pp An optional strength can be supplied on a separate line which refers to the current magic description using the following format: .Bd -literal -offset indent !:strength OP VALUE .Ed .Pp The operand .Dv OP can be: .Dv + , .Dv - , .Dv * , or .Dv / and .Dv VALUE is a constant between 0 and 255. This constant is applied using the specified operand to the currently computed default magic strength. .Pp Some file formats contain additional information which is to be printed along with the file type or need additional tests to determine the true file type. These additional tests are introduced by one or more .Em \*[Gt] characters preceding the offset. The number of .Em \*[Gt] on the line indicates the level of the test; a line with no .Em \*[Gt] at the beginning is considered to be at level 0. Tests are arranged in a tree-like hierarchy: if the test on a line at level .Em n succeeds, all following tests at level .Em n+1 are performed, and the messages printed if the tests succeed, until a line with level .Em n (or less) appears. For more complex files, one can use empty messages to get just the "if/then" effect, in the following way: .Bd -literal -offset indent 0 string MZ \*[Gt]0x18 leshort \*[Lt]0x40 MS-DOS executable \*[Gt]0x18 leshort \*[Gt]0x3f extended PC executable (e.g., MS Windows) .Ed .Pp Offsets do not need to be constant, but can also be read from the file being examined. If the first character following the last .Em \*[Gt] is a .Em \&( then the string after the parenthesis is interpreted as an indirect offset. That means that the number after the parenthesis is used as an offset in the file. The value at that offset is read, and is used again as an offset in the file. Indirect offsets are of the form: .Em (( x [.[bislBISL]][+\-][ y ]) . The value of .Em x is used as an offset in the file. A byte, id3 length, short or long is read at that offset depending on the .Em [bislBISLm] type specifier. The capitalized types interpret the number as a big endian value, whereas the small letter versions interpret the number as a little endian value; the .Em m type interprets the number as a middle endian (PDP-11) value. To that number the value of .Em y is added and the result is used as an offset in the file. The default type if one is not specified is long. .Pp That way variable length structures can be examined: .Bd -literal -offset indent # MS Windows executables are also valid MS-DOS executables 0 string MZ \*[Gt]0x18 leshort \*[Lt]0x40 MZ executable (MS-DOS) # skip the whole block below if it is not an extended executable \*[Gt]0x18 leshort \*[Gt]0x3f \*[Gt]\*[Gt](0x3c.l) string PE\e0\e0 PE executable (MS-Windows) \*[Gt]\*[Gt](0x3c.l) string LX\e0\e0 LX executable (OS/2) .Ed .Pp This strategy of examining has a drawback: You must make sure that you eventually print something, or users may get empty output (like, when there is neither PE\e0\e0 nor LE\e0\e0 in the above example) .Pp If this indirect offset cannot be used directly, simple calculations are possible: appending .Em [+-*/%\*[Am]|^]number inside parentheses allows one to modify the value read from the file before it is used as an offset: .Bd -literal -offset indent # MS Windows executables are also valid MS-DOS executables 0 string MZ # sometimes, the value at 0x18 is less that 0x40 but there's still an # extended executable, simply appended to the file \*[Gt]0x18 leshort \*[Lt]0x40 \*[Gt]\*[Gt](4.s*512) leshort 0x014c COFF executable (MS-DOS, DJGPP) \*[Gt]\*[Gt](4.s*512) leshort !0x014c MZ executable (MS-DOS) .Ed .Pp Sometimes you do not know the exact offset as this depends on the length or position (when indirection was used before) of preceding fields. You can specify an offset relative to the end of the last up-level field using .Sq \*[Am] as a prefix to the offset: .Bd -literal -offset indent 0 string MZ \*[Gt]0x18 leshort \*[Gt]0x3f \*[Gt]\*[Gt](0x3c.l) string PE\e0\e0 PE executable (MS-Windows) # immediately following the PE signature is the CPU type \*[Gt]\*[Gt]\*[Gt]\*[Am]0 leshort 0x14c for Intel 80386 \*[Gt]\*[Gt]\*[Gt]\*[Am]0 leshort 0x184 for DEC Alpha .Ed .Pp Indirect and relative offsets can be combined: .Bd -literal -offset indent 0 string MZ \*[Gt]0x18 leshort \*[Lt]0x40 \*[Gt]\*[Gt](4.s*512) leshort !0x014c MZ executable (MS-DOS) # if it's not COFF, go back 512 bytes and add the offset taken # from byte 2/3, which is yet another way of finding the start # of the extended executable \*[Gt]\*[Gt]\*[Gt]\*[Am](2.s-514) string LE LE executable (MS Windows VxD driver) .Ed .Pp Or the other way around: .Bd -literal -offset indent 0 string MZ \*[Gt]0x18 leshort \*[Gt]0x3f \*[Gt]\*[Gt](0x3c.l) string LE\e0\e0 LE executable (MS-Windows) # at offset 0x80 (-4, since relative offsets start at the end # of the up-level match) inside the LE header, we find the absolute # offset to the code area, where we look for a specific signature \*[Gt]\*[Gt]\*[Gt](\*[Am]0x7c.l+0x26) string UPX \eb, UPX compressed .Ed .Pp Or even both! .Bd -literal -offset indent 0 string MZ \*[Gt]0x18 leshort \*[Gt]0x3f \*[Gt]\*[Gt](0x3c.l) string LE\e0\e0 LE executable (MS-Windows) # at offset 0x58 inside the LE header, we find the relative offset # to a data area where we look for a specific signature \*[Gt]\*[Gt]\*[Gt]\*[Am](\*[Am]0x54.l-3) string UNACE \eb, ACE self-extracting archive .Ed .Pp If you have to deal with offset/length pairs in your file, even the second value in a parenthesized expression can be taken from the file itself, using another set of parentheses. Note that this additional indirect offset is always relative to the start of the main indirect offset. .Bd -literal -offset indent 0 string MZ \*[Gt]0x18 leshort \*[Gt]0x3f \*[Gt]\*[Gt](0x3c.l) string PE\e0\e0 PE executable (MS-Windows) # search for the PE section called ".idata"... \*[Gt]\*[Gt]\*[Gt]\*[Am]0xf4 search/0x140 .idata # ...and go to the end of it, calculated from start+length; # these are located 14 and 10 bytes after the section name \*[Gt]\*[Gt]\*[Gt]\*[Gt](\*[Am]0xe.l+(-4)) string PK\e3\e4 \eb, ZIP self-extracting archive .Ed .Pp If you have a list of known avalues at a particular continuation level, and you want to provide a switch-like default case: .Bd -literal -offset indent # clear that continuation level match \*[Gt]18 clear \*[Gt]18 lelong 1 one \*[Gt]18 lelong 2 two \*[Gt]18 default x # print default match \*[Gt]\*[Gt]18 lelong x unmatched 0x%x .Ed .Sh SEE ALSO .Xr file __CSECTION__ \- the command that reads this file. .Sh BUGS The formats .Dv long , .Dv belong , .Dv lelong , .Dv melong , .Dv short , .Dv beshort , and .Dv leshort do not depend on the length of the C data types .Dv short and .Dv long on the platform, even though the Single .Ux Specification implies that they do. However, as OS X Mountain Lion has passed the Single .Ux Specification validation suite, and supplies a version of .Xr file __CSECTION__ in which they do not depend on the sizes of the C data types and that is built for a 64-bit environment in which .Dv long is 8 bytes rather than 4 bytes, presumably the validation suite does not test whether, for example .Dv long refers to an item with the same size as the C data type .Dv long . There should probably be .Dv type names .Dv int8 , .Dv uint8 , .Dv int16 , .Dv uint16 , .Dv int32 , .Dv uint32 , .Dv int64 , and .Dv uint64 , and specified-byte-order variants of them, to make it clearer that those types have specified widths. .\" .\" From: guy@sun.uucp (Guy Harris) .\" Newsgroups: net.bugs.usg .\" Subject: /etc/magic's format isn't well documented .\" Message-ID: <2752@sun.uucp> .\" Date: 3 Sep 85 08:19:07 GMT .\" Organization: Sun Microsystems, Inc. .\" Lines: 136 .\" .\" Here's a manual page for the format accepted by the "file" made by adding .\" the changes I posted to the S5R2 version. .\" .\" Modified for Ian Darwin's version of the file command.

The files are installed in /usr/share/mk, and are by convention, named with the suffix ".mk". These files store several build options and should be handled with caution. Note, this file is not intended to replace reading through the .mk files for anything tricky. There are two main types of make include files. One type is the generally usable make include files, such as bsd.prog.mk and bsd.lib.mk. The other is the internal make include files, such as bsd.files.mk and bsd.man.mk, which can not/should not be used directly but are used by the other make include files. In most cases it is only interesting to include bsd.prog.mk or bsd.lib.mk. bsd.arch.inc.mk - includes arch-specific Makefile.$arch bsd.compiler.mk - defined based on current compiler bsd.cpu.mk - sets CPU/arch-related variables (included from sys.mk) bsd.dep.mk - handle Makefile dependencies bsd.doc.mk - building troff system documents bsd.endian.mk - TARGET_ENDIAN=1234(little) or 4321 (big) for target bsd.files.mk - install of general purpose files bsd.incs.mk - install of include files bsd.info.mk - building GNU Info hypertext system (deprecated) bsd.init.mk - initialization for the make include files bsd.kmod.mk - building loadable kernel modules bsd.lib.mk - support for building libraries bsd.libnames.mk - define library names bsd.links.mk - install of links (sym/hard) bsd.man.mk - install of manual pages and their links bsd.nls.mk - build and install of NLS catalogs bsd.obj.mk - creating 'obj' directories and cleaning up bsd.own.mk - define common variables bsd.port.mk - building ports bsd.port.post.mk - building ports bsd.port.pre.mk - building ports bsd.port.subdir.mk - targets for building subdirectories for ports bsd.prog.mk - building programs from source files bsd.progs.mk - build multiple programs from sources (deprecated) bsd.snmpmod.mk - building modules for the SNMP daemon bsnmpd bsd.subdir.mk - targets for building subdirectories bsd.sys.mk - common settings used for building FreeBSD sources bsd.test.mk - building test programs from source files sys.mk - default rules for all makes This file does not document bsd.port*.mk. They are documented in ports(7). See also make(1), mkdep(1), style.Makefile(5) and `PMake - A Tutorial', located in /usr/share/doc/psd/12.make. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Random things worth knowing about this document: If appropriate when documenting the variables the default value is indicated using square brackets e.g. [gzip]. In some cases the default value depend on other values (e.g. system architecture). In these cases the most common value is indicated. This document contains some simple examples of the usage of the BSD make include files. For more examples look at the makefiles in the FreeBSD source tree. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= RANDOM THINGS WORTH KNOWING: The files are like C-style #include files, and pretty much behave like you'd expect. The syntax is slightly different in that a single '.' is used instead of the hash mark, i.e. ".include ". One difference that will save you lots of debugging time is that inclusion of the file is normally done at the *end* of the Makefile. The reason for this is because .mk files often modify variables and behavior based on the values of variables set in the Makefile. To make this work, remember that the FIRST target found is the target that is used, i.e. if the Makefile has: a: echo a a: echo a number two the command "make a" will echo "a". To make things confusing, the SECOND variable assignment is the overriding one, i.e. if the Makefile has: a= foo a= bar b: echo ${a} the command "make b" will echo "bar". This is for compatibility with the way the V7 make behaved. It's fairly difficult to make the BSD .mk files work when you're building multiple programs in a single directory. It's a lot easier to split up the programs than to deal with the problem. Most of the agony comes from making the "obj" directory stuff work right, not because we switch to a new version of make. So, don't get mad at us, figure out a better way to handle multiple architectures so we can quit using the symbolic link stuff. (Imake doesn't count.) The file .depend in the source directory is expected to contain dependencies for the source files. This file is read automatically by make after reading the Makefile. The variable DESTDIR works as before. It's not set anywhere but will change the tree where the file gets installed. The profiled libraries are no longer built in a different directory than the regular libraries. A new suffix, ".po", is used to denote a profiled object. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The following variables are common: CFLAGS.${COMPILER_TYPE} Flags dependent on compiler added to CXXFLAGS. CFLAGS.${MACHINE_ARCH} Architectural flags added to CFLAGS. CFLAGS_NO_SIMD Add this to CFLAGS for programs that don't want any SIMD instructions generated. It is setup in bsd.cpu.mk to an appropriate value for the compiler and target. CXXFLAGS.${COMPILER_TYPE} Flags dependent on compiler added to CXXFLAGS. CXXFLAGS.${MACHINE_ARCH} Architectural flags added to CXXFLAGS. COMPILER_FEATURES A list of features that the compiler supports. Zero or more of: c++11 Supports full C++ 11 standard. COMPILER_TYPE Type of compiler, either clang or gcc, though other values are possible. Don't assume != clang == gcc. COMPILER_VERSION A numeric constant equal to: major * 10000 + minor * 100 + tiny for the compiler's self-reported version. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The include file has the default rules for all makes, in the BSD environment or otherwise. You probably don't want to touch this file. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The include file includes other Makefiles for specific architectures, if they exist. It will include the first of the following files that it finds: Makefile.${MACHINE}, Makefile.${MACHINE_ARCH}, Makefile.${MACHINE_CPUARCH} =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The include file handles installing manual pages and their links. It has three targets: all-man: build manual pages. maninstall: install the manual pages and their links. manlint: verify the validity of manual pages. It sets/uses the following variables: MANDIR Base path for manual installation. MANGRP Manual group. MANOWN Manual owner. MANMODE Manual mode. MANSUBDIR Subdirectory under the manual page section, i.e. "/vax" or "/tahoe" for machine specific manual pages. MAN The manual pages to be installed (use a .1 - .9 suffix). MLINKS List of manual page links (using a .1 - .9 suffix). The linked-to file must come first, the linked file second, and there may be multiple pairs. The files are hard-linked. The include file includes a file named "../Makefile.inc" if it exists. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The include file contains the owners, groups, etc. for both manual pages and binaries. It has no targets. It sets/uses the following variables: BINGRP Binary group. BINOWN Binary owner. BINMODE Binary mode. MANDIR Base path for manual installation. MANGRP Manual group. MANOWN Manual owner. MANMODE Manual mode. This file is generally useful when building your own Makefiles so that they use the same default owners etc. as the rest of the tree. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The include file handles building programs from one or more source files, along with their manual pages. It has a limited number of suffixes, consistent with the current needs of the BSD tree. It has seven targets: all: build the program and its manual page clean: remove the program and any object files. cleandir: remove all of the files removed by the target clean, as well as .depend, tags, and any manual pages. depend: make the dependencies for the source files, and store them in the file .depend. install: install the program and its manual pages; if the Makefile does not itself define the target install, the targets beforeinstall and afterinstall may also be used to cause actions immediately before and after the install target is executed. lint: run lint on the source files tags: create a tags file for the source files. It sets/uses the following variables: BINGRP Binary group. BINOWN Binary owner. BINMODE Binary mode. CLEANFILES Additional files to remove and CLEANDIRS additional directories to remove during clean and cleandir targets. "rm -f" and "rm -rf" used respectively. CFLAGS Flags to the compiler when creating C objects. FILES A list of non-executable files. The installation is controlled by the FILESNAME, FILESOWN, FILESGRP, FILESMODE, FILESDIR variables that can be further specialized by FILES_. LDADD Additional loader objects. Usually used for libraries. For example, to load with the compatibility and utility libraries, use: LDADD=-lutil -lcompat +LIBADD Additional libraries. This is for base system libraries + and is only valid inside of the /usr/src tree. + Rather than use LDADD=-lname use LIBADD=name. + LDFLAGS Additional loader flags. Passed to the loader via CC, since that's used to link programs as well, so loader specific flags need to be prefixed with -Wl, to work. LINKS The list of binary links; should be full pathnames, the linked-to file coming first, followed by the linked file. The files are hard-linked. For example, to link /bin/test and /bin/[, use: LINKS= ${DESTDIR}/bin/test ${DESTDIR}/bin/[ MAN Manual pages (should end in .1 - .9). If no MAN variable is defined, "MAN=${PROG}.1" is assumed. PROG The name of the program to build. If not supplied, nothing is built. PROG_CXX If defined, the name of the program to build. Also causes to link the program with the standard C++ library. PROG_CXX overrides the value of PROG if PROG is also set. +PROGS When used with , allow building multiple +PROGS_CXX PROG and PROGS_CXX in one Makefile. To define + individual variables for each program the VAR.prog + syntax should be used. For example: + + PROGS= foo bar + SRCS.foo= foo_src.c + LDADD.foo= -lutil + SRCS.bar= bar_src.c + + The supported variables are BINDIR BINGRP BINMODE BINOWN + CFLAGS CPPFLAGS CXXFLAGS DPADD DPLIBS DPSRCS LDADD + LDFLAGS LIBADD MAN MLINKS PROGNAME SRCS. + PROGNAME The name that the above program will be installed as, if different from ${PROG}. SRCS List of source files to build the program. If SRCS is not defined, it's assumed to be ${PROG}.c or, if PROG_CXX is defined, ${PROG_CXX}.cc. DPADD Additional dependencies for the program. Usually used for libraries. For example, to depend on the compatibility and utility libraries use: DPADD=${LIBCOMPAT} ${LIBUTIL} There is a predefined identifier for each (non-profiled, non-shared) library and object. Library file names are transformed to identifiers by removing the extension and converting to upper case. There are no special identifiers for profiled or shared libraries or objects. The identifiers for the standard libraries are used in DPADD. This works correctly iff all the libraries are built at the same time. Unfortunately, it causes unnecessary relinks to shared libraries when only the static libraries have changed. Dependencies on shared libraries should be only on the library version numbers. STRIP The flag passed to the install program to cause the binary to be stripped. This is to be used when building your own install script so that the entire system can be made stripped/not-stripped using a single nob. SUBDIR A list of subdirectories that should be built as well. Each of the targets will execute the same target in the subdirectories. SCRIPTS A list of interpreter scripts [file.{sh,csh,pl,awk,...}]. The installation is controlled by the SCRIPTSNAME, SCRIPTSOWN, SCRIPTSGRP, SCRIPTSMODE, SCRIPTSDIR variables that can be further specialized by SCRIPTS_
