This information includes security advisories, as well as news relating to the software or documentation that could affect its operation or usability. An up-to-date version of this document should always be consulted before installing this version of &os;.

Any version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the current errata for this release. These other copies of the errata are located at , plus any sites which keep up-to-date mirrors of this location. Source and binary snapshots of &os; &release.branch; also contain up-to-date copies of this document (as of the time of the snapshot). For a list of all &os; CERT security advisories, see .

It depends on some specific hardware configuration and does not depend on a specific version of VirtualBox or host operating system. It has been reported that instability may be present on virtual machines running on other hypervisors, such as Xen or KVM. It causes various errors and makes &os; quite unstable. Although the cause is still unclear, disabling unmapped I/O works as a workaround. To disable it, choose Escape to loader prompt in the boot menu and enter the following lines from &man.loader.8; prompt, after an OK: set vfs.unmapped_buf_allowed=0 boot Note that the following line has to be added to /boot/loader.conf after a boot. It disables unmapped I/O at every boot: vfs.unmapped_buf_allowed=0 &os;/&arch.i386; &release.prev; installed on ZFS may crash during boot when the ZFS pool mount is attempted while booting an unmodified GENERIC kernel. As described in /usr/src/UPDATING entry 20121223, rebuilding the kernel with options KSTACK_PAGES=4 has been observed to resolve the boot-time crash. This, however, is not an ideal solution for inclusion in the GENERIC kernel configuration, as increasing KSTACK_PAGES implicitly decreases available usermode threads in an environment that is already resource-starved. Taking into account the heavy resource requirements of ZFS, in addition to the &arch.i386;-specific tuning requirements for general workloads, using ZFS with the &os;/&arch.i386; GENERIC kernel is strongly discouraged. If installing &os;/&arch.i386; on ZFS, it is possible to configure the system after installation to increase the KSTACK_PAGES. When prompted by &man.bsdinstall.8; to perform additional post-installation configuration to the system, select [ YES ]. This procedure requires the system sources available locally. If the System source code distribution was not selected during installation, it can be obtained using svnlite: &prompt.root; mkdir -p /usr/src &prompt.root; svnlite co https://svn.freebsd.org/base/releng/10.4 /usr/src Build the kernel-toolchain required to rebuild the kernel: &prompt.root; make -C /usr/src kernel-toolchain Next, create a kernel configuration file to increase the KSTACK_PAGES option: &prompt.root; printf "include GENERIC\noptions KSTACK_PAGES=4\n" > /usr/src/sys/i386/conf/ZFS Then build and install the ZFS kernel: &prompt.root; make -C /usr/src buildkernel KERNCONF=ZFS &prompt.root; make -C /usr/src installkernel KERNCONF=ZFS It is extremely important to take note that, by default, &man.freebsd-update.8; will install the GENERIC kernel configuration, and as such, &man.freebsd-update.8; consumers are strongly encouraged to avoid &os;-provided kernel binary upgrades with such configurations. Due to an incompatibility between &man.bsdconfig.8; and &man.pkg.8;, packages included on the &os; dvd installer will not be recognized by &man.bsdconfig.8;. To install packages from the dvd1.iso installer, create the /dist target directory, and manually mount the dvd1.iso ISO: &prompt.root; mkdir -p /dist &prompt.root; mount -t cd9660 /dev/cd0 /dist Be sure to use the correct /dev device path for the dvd1.iso ISO installer. Next, set REPOS_DIR to the path of the repos/ directory within the installer so &man.pkg.8; will use the correct repository metadata. If using &man.sh.1;: &prompt.root; export REPOS_DIR=/dist/packages/repos If using &man.csh.1;: &prompt.root; setenv REPOS_DIR /dist/packages/repos Keep in mind that REPOS_DIR will need to be set again after the current shell session is terminated, if continuing to use the packages provided on the dvd1.iso installer. Finally, bootstrap &man.pkg.8; from the ISO, and install required packages: &prompt.root; pkg bootstrap &prompt.root; pkg install xorg-server xorg gnome3 [...] An issue with &os; virtual machines with vagrant was discovered that affects the VirtualBox where the virtual machine will not start on the initial boot invoked with vagrant up. The issue is due to the virtual machine MAC being unset, as &os; does not provide a default Vagrantfile. It has been observed, however, that a subsequent invocation of vagrant up will allow the virtual machine to successfully boot, allowing access via vagrant ssh. Late-Breaking News No news.

Security Advisories &security; Errata Notices &errata; Open Issues &os;/&arch.i386; installed on ZFS may crash during boot when the ZFS pool mount is attempted while booting an unmodified GENERIC kernel. A system tunable has been added as of revision r286584 to make the kern.kstack_pages tunable configurable without recompiling the kernel. To mitigate system crashes with such configurations, choose Escape to loader prompt in the boot menu and enter the following lines from &man.loader.8; prompt, after an OK: set kern.kstack_pages=4 boot Add this line to /boot/loader.conf for the change to persist across reboots: kern.kstack_pages=4 [2017-07-21] Due to a bug in earlier versions of &man.clang.1; that is difficult to work around in the upgrade process, to upgrade the system from sources via buildworld to -CURRENT or &release;, it is necessary to upgrade machines running 9.x to at least revision r286035, or machines running 10.x to revision r286033. Source-based upgrades from 10.3-RELEASE are not affected. This differs from the historical situation where one could generally upgrade from anywhere on earlier stable branches, so caution should be exercised. [2017-07-25] &os;/&arch.arm64; currently lacks EFI real-time clock (RTC) support, which may cause the system to boot with the wrong time set. As a workaround, either enable &man.ntpdate.8; or include ntpd_sync_on_start="YES" in &man.rc.conf.5;. [2017-07-25] A late issue was discovered with &os;/&arch.arm64; and "root on ZFS" installations where the root ZFS pool would fail to be located. There currently is no workaround. [2017-07-26] Note for those upgrading from 11.1-RC2 in VirtualBox: If system panics were experienced when upgrading from 11.1-RC1 to 11.1-RC2, and the emulators/virtualbox-ose-additions{,-nox11} port was built locally as a resolution, the port will either need to be rebuilt when upgrading from 11.1-RC2 to 11.1-RELEASE, or reinstall the package from the pkg(8) mirrors using either: &prompt.root; pkg install -f virtualbox-ose-additions or &prompt.root; pkg install -f virtualbox-ose-additions-nox11 To ensure the system does not panic after rebooting into the updated kernel, it is recommended to disable the vboxguest service in &man.rc.conf.5; prior to rebooting the system if possible, or use &man.pkg.8; to forcefully reinstall the package. Systems being upgraded from 11.1-RC1 and earlier and 11.1-RC3 to 11.1-RELEASE should be unaffected. [2017-07-27] The release notes erroneously state revision r315330 was sponsored by Rubicon Communications, LLC (Netgate), when in fact this work was done by Hiroki Mori independently. [2017-08-09] The release notes stated the &man.ruptime.1;, &man.rwho.1;, and &man.rwhod.8; utilities have been marked "deprecated", however this change was reversed in 12.0-CURRENT. The other utilities mentioned in the entry in the release notes, however, are unchanged. [2017-11-06] An issue with &os; virtual machines with vagrant was discovered that affects the VirtualBox where the virtual machine will not start on the initial boot invoked with vagrant up. The issue is due to the virtual machine MAC being unset, as &os; does not provide a default Vagrantfile. It has been observed, however, that a subsequent invocation of vagrant up will allow the virtual machine to successfully boot, allowing access via vagrant ssh. Late-Breaking News No news.
