The following meta-characters are recognized in patterns: .Bl -tag -width "...." -compact .It Li ! If this is the first character of the pattern, invert the sense of the pattern match. .It Li * Matches any string of characters in a symbol name. .It Li ?

A capability to the casper process obtained with the .Fn cap_init function allows to create capabilities to casper's services via the .Fn cap_service_open function. .Pp The .Fn cap_init function opens capability to the casper process. .Pp The .Fn cap_wrap function creates .Vt cap_channel_t based on the given socket. The function is used when capability is inherited through .Xr execve 2 or send over .Xr unix 4 domain socket as a regular file descriptor and has to be represented as .Vt cap_channel_t again. The .Fa flags argument defines the channel behavior. The supported flags are: .Bl -ohang -offset indent .It CASPER_NO_UNIQ The communication between process and casper uses no unique version of nvlist. .El .Pp The .Fn cap_unwrap function is the opposite of the .Fn cap_wrap function. It frees the .Vt cap_channel_t structure and returns .Xr unix 4 domain socket associated with it. .Pp The .Fn cap_clone function clones the given capability. .Pp The .Fn cap_close function closes the given capability. .Pp The .Fn cap_sock function returns .Xr unix 4 domain socket descriptor associated with the given capability for use with system calls like .Xr kevent 2 , .Xr poll 2 and .Xr select 2 . .Pp The .Fn cap_limit_get function stores current limits of the given capability in the .Fa limitsp argument. If the function return .Va 0 and .Dv NULL is stored in .Fa limitsp it means there are no limits set. .Pp The .Fn cap_limit_set function sets limits for the given capability. The limits are provided as a .Xr nvlist 9 . The exact format depends on the service the capability represents. .Fn cap_limit_set frees the limits regardless of whether the operation succeeds or fails. .Pp The .Fn cap_send_nvlist function sends the given .Xr nvlist 9 over the given capability. This is low level interface to communicate with casper services. Most services should provide higher level API. .Pp The .Fn cap_recv_nvlist function receives the given .Xr nvlist 9 over the given capability. .Pp The .Fn cap_xfer_nvlist function sends the given .Xr nvlist 9 , destroys it and receives new .Xr nvlist 9 in response over the given capability. It does not matter if the function succeeds or fails, the .Xr nvlist 9 given for sending will always be destroyed once the function returns. .Pp The .Fn cap_service_open function opens casper service of the given name through casper capability obtained via the .Fn cap_init function. The function returns capability that provides access to opened service. Casper supports the following services in the base system: .Bl -tag -width "system.random" -compact -offset indent .Pp .It system.dns provides DNS libc compatible API .It system.grp provides .Xr getgrent 3 compatible API .It system.pwd provides .Xr getpwent 3 compatible API -.It system.random -allows to obtain entropy from -.Pa /dev/random .It system.sysctl provides .Xr sysctlbyname 3 compatible API .It system.syslog provides .Xr syslog 3 compatible API .Sh RETURN VALUES The .Fn cap_clone , .Fn cap_init , .Fn cap_recv_nvlist , .Fn cap_service_open , .Fn cap_wrap and .Fn cap_xfer_nvlist functions return .Dv NULL and set the .Va errno variable on failure. .Pp The .Fn cap_limit_get , .Fn cap_limit_set and .Fn cap_send_nvlist functions return .Dv -1 and set the .Va errno variable on failure. .Pp The .Fn cap_close , .Fn cap_sock and .Fn cap_unwrap functions always succeed. .Sh SEE ALSO .Xr errno 2 , .Xr execve 2 , .Xr kevent 2 , .Xr poll 2 , .Xr select 2 , .Xr cap_dns 3 , .Xr cap_grp 3 , .Xr cap_pwd 3 , .Xr cap_sysctl 3 , .Xr cap_syslog 3 , .Xr libcasper_service 3 , .Xr capsicum 4 , .Xr unix 4 , .Xr nv 9 .Sh AUTHORS The .Nm libcasper library was implemented by .An Pawel Jakub Dawidek Aq Mt pawel@dawidek.net under sponsorship from the FreeBSD Foundation.

Idea behind the library is that we are passing a remaining .Fa argc and .Fa argv which contains a list of files that should be open for this program. The library will create a service that will serve those files. .Pp The function .Fn fileargs_init create a service to the .Nm system.fileargs . The .Fa argv contains a list of files that should be opened. The argument can be set to .Dv NULL which will not create a service and all files will be prohibited to be opened. The .Fa argc argument contains a number of passed files. The .Fa flags argument limits opened files for either execution or reading and/or writing. The .Fa mode argument tells which what mode file should be created if the .Dv O_CREATE flag is present . For more details of the .Fa flags and .Fa mode arguments see .Xr open 2 . The .Fa rightsp argument contains a list of the capability rights which file should be limited to. For more details of the capability rights see .Xr cap_rights_init 3 . The .Fa operations argument limits the operations that are available using .Nm system.fileargs . .Fa operations is a combination of: .Bl -ohang -offset indent .It FA_OPEN Allow .Fn fileargs_open and .Fn fileargs_fopen . .It FA_LSTAT Allow .Fn fileargs_lstat . .El .Pp The function .Fn fileargs_cinit is equivalent to .Fn fileargs_init except that the connection to the Casper needs to be provided. .Pp The functions .Fn fileargs_initnv and .Fn fileargs_cinitnv are respectively equivalent to .Fn fileargs_init and .Fn fileargs_cinit expect that all arguments all provided as .Xr nvlist 9 . For details see .Sx LIMITS . .Pp The .Fa fileargs_free close connection to the .Nm system.fileargs service and free are structures. The function handle .Dv NULL argument. .Pp The function .Fn fileargs_lstat is equivalent to .Xr lstat 2 . .Pp The functions .Fn fileargs_open and .Fn fileargs_fopen are respectively equivalent to .Xr open 2 and .Xr fopen 3 expect that all arguments are fetched from the .Va fileargs_t structure. .Sh LIMITS This section describe which values and types should be used to pass arguments to the .Fa system.fileargs through the .Fn fileargs_initnv and .Fn fileargs_cinitnv functions. The .Xr nvlist 9 for that functions must contain the following values and types: .Bl -ohang -offset indent .It flags ( NV_TYPE_NUMBER ) The .Va flags limits opened files for either execution or reading and/or writing. .It mode (NV_TYPE_NUMBER) If in the .Va flags argument the .Dv O_CREATE flag was defined the .Xr nvlist 9 must contain the .Va mode . The .Va mode argument tells which what mode file should be created. .It operations (NV_TYPE_NUMBER) The .Va operations limits the usable operations for .Fa system.fileargs . The possible values are explained as .Va operations argument with .Fn fileargs_init . .El .Pp The .Xr nvlist 9 for that functions may contain the following values and types: .Bl -ohang -offset indent .It cap_rights ( NV_TYPE_BINARY ) The .Va cap_rights argument contains a list of the capability rights which file should be limited to. .It ( NV_TYPE_NULL ) Any number of .Dv NV_TYPE_NULL where the name of the element is name of the file which can be opened. .Sh EXAMPLES The following example first parse some options and then create the .Nm system.fileargs service with remaining arguments. .Bd

Thus, the apic device is not strictly an SMP option, # but it is a prerequisite for SMP. # # Notes: # # HTT CPUs should only be used if they are enabled in the BIOS. For # the ACPI case, ACPI only correctly tells us about any HTT CPUs if # they are enabled. However, most HTT systems do not list HTT CPUs # in the MP Table if they are enabled, thus we guess at the HTT CPUs # for the MP Table case. However, we shouldn't try to guess and use # these CPUs if HTT is disabled. Thus, HTT guessing is only enabled # for the MP Table if the user explicitly asks for it via the # MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT # disabled in your BIOS. # # IPI_PREEMPTION instructs the kernel to preempt threads running on other # CPUS if needed.

The default is double-clock mode on # BlueLightning CPU box. # # CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM # BlueLightning CPU. It works only with Cyrix FPU, and this option # should not be used with Intel FPU. # # CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). # # CPU_CYRIX_NO_LOCK enables weak locking for the entire address space # of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. # Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) # # CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct # mapped mode. Default is 2-way set associative mode. # # CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables # reorder). This option should not be used if you use memory mapped # I/O device(s). # # CPU_ELAN enables support for AMDs ElanSC520 CPU. # CPU_ELAN_PPS enables precision timestamp code. # CPU_ELAN_XTAL sets the clock crystal frequency in Hz. # # CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun # technology which allows to restrict power consumption of the CPU by # using group of hw.crusoe.* sysctls. # # CPU_FASTER_5X86_FPU enables faster FPU exception handler. # # CPU_GEODE is for the SC1100 Geode embedded processor. This option # is necessary because the i8254 timecounter is toast. # # CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products # for i386 machines. # # CPU_IORT defines I/O clock delay time (NOTE 1). Default values of # I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively # (no clock delay). # # CPU_L2_LATENCY specifies the L2 cache latency value. This option is used # only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. # The default value is 5. # # CPU_LOOP_EN prevents flushing the prefetch buffer if the destination # of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE # 1). # # CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option # is useful when you use Socket 8 to Socket 370 converter, because most Pentium # Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. # # CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). # # CPU_SOEKRIS enables support www.soekris.com hardware. # # CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU # enters suspend mode following execution of HALT instruction. # # CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). # # CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD # K5/K6/K6-2 CPUs. # # CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache # flush at hold state. # # CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs # without cache flush at hold state, and (2) write-back CPU cache on # Cyrix 6x86 whose revision < 2.7 (NOTE 2). # # NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY # Pentiums) from locking up when a LOCK CMPXCHG8B instruction is # executed. This option is only needed if I586_CPU is also defined, # and should be included for any non-Pentium CPU that defines it. # # NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors # which indicates that the 15-16MB range is *definitely* not being # occupied by an ISA memory hole. # # NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, # CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. # These options may crash your system. # # NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled # in write-through mode when revision < 2.7. If revision of Cyrix # 6x86 >= 2.7, CPU cache is always enabled in write-back mode. # # NOTE 3: This option may cause failures for software that requires # locked cycles in order to operate correctly. # options CPU_ATHLON_SSE_HACK options CPU_BLUELIGHTNING_3X options CPU_BLUELIGHTNING_FPU_OP_CACHE options CPU_BTB_EN options CPU_DIRECT_MAPPED_CACHE options CPU_DISABLE_5X86_LSSER options CPU_ELAN options CPU_ELAN_PPS options CPU_ELAN_XTAL=32768000 options CPU_ENABLE_LONGRUN options CPU_FASTER_5X86_FPU options CPU_GEODE options CPU_I486_ON_386 options CPU_IORT options CPU_L2_LATENCY=5 options CPU_LOOP_EN options CPU_PPRO2CELERON options CPU_RSTK_EN options CPU_SOEKRIS options CPU_SUSP_HLT options CPU_UPGRADE_HW_CACHE options CPU_WT_ALLOC options CYRIX_CACHE_WORKS options CYRIX_CACHE_REALLY_WORKS #options NO_F00F_HACK # Debug options options NPX_DEBUG # enable npx debugging # # PERFMON causes the driver for Pentium/Pentium Pro performance counters # to be compiled.

The drawback is a moderate (up to 1/HZ seconds) # potential increase in response times. # It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING # to achieve smoother behaviour. # Additionally, you can enable/disable polling at runtime with help of # the ifconfig(8) utility, and select the CPU fraction reserved to # userland with the sysctl variable kern.polling.user_frac # (default 50, range 0..100). # # Not all device drivers support this mode of operation at the time of # this writing.

This saves about 0.7-1.25 usec for each interrupt. # This option breaks suspend/resume on some portables. # # AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A # interrupt controller. This saves about 0.7-1.25 usec for each interrupt. # Automatic EOI is documented not to work for for the slave with the # original i8259A, but it works for some clones and some integrated # versions. # # MAXMEM specifies the amount of RAM on the machine; if this is not # specified, FreeBSD will first read the amount of memory from the CMOS # RAM, so the amount of memory will initially be limited to 64MB or 16MB # depending on the BIOS.

Adler first version with partial lookup tables - b2 21 Mar 92 M. Adler fixed bug in fixed-code blocks - b3 22 Mar 92 M. Adler sped up match copies, cleaned up some - b4 25 Mar 92 M. Adler added prototypes; removed window[] (now - is the responsibility of unzip.h--also - changed name to slide[]), so needs diffs - for unzip.c and unzip.h (this allows - compiling in the small model on MSDOS); - fixed cast of q in huft_build(); - b5 26 Mar 92 M.

The compression - method searches for as much of the current string of bytes (up to a - length of 258) in the previous 32K bytes. If it doesn't find any - matches (of at least length 3), it codes the next byte. Otherwise, it - codes the length of the matched string and its distance backwards from - the current position. There is a single Huffman code that codes both - single bytes (called "literals") and match lengths. A second Huffman - code codes the distance information, which follows a length code. Each - length or distance code actually represents a base value and a number - of "extra" (sometimes zero) bits to get to add to the base value. At - the end of each deflated block is a special end-of-block (EOB) literal/ - length code. The decoding process is basically: get a literal/length - code; if EOB then done; if a literal, emit the decoded byte; if a - length then get the distance and emit the referred-to bytes from the - sliding window of previously emitted data. - - There are (currently) three kinds of inflate blocks: stored, fixed, and - dynamic. The compressor outputs a chunk of data at a time and decides - which method to use on a chunk-by-chunk basis. A chunk might typically - be 32K to 64K, uncompressed. If the chunk is uncompressible, then the - "stored" method is used. In this case, the bytes are simply stored as - is, eight bits per byte, with none of the above coding. The bytes are - preceded by a count, since there is no longer an EOB code. - - If the data is compressible, then either the fixed or dynamic methods - are used. In the dynamic method, the compressed data is preceded by - an encoding of the literal/length and distance Huffman codes that are - to be used to decode this block. The representation is itself Huffman - coded, and so is preceded by a description of that code. These code - descriptions take up a little space, and so for small blocks, there is - a predefined set of codes, called the fixed codes. The fixed method is - used if the block ends up smaller that way (usually for quite small - chunks); otherwise the dynamic method is used. In the latter case, the - codes are customized to the probabilities in the current block and so - can code it much better than the pre-determined fixed codes can. - - The Huffman codes themselves are decoded using a mutli-level table - lookup, in order to maximize the speed of decoding plus the speed of - building the decoding tables. See the comments below that precede the - lbits and dbits tuning parameters. - */ - - -/* - Notes beyond the 1.93a appnote.txt: - - 1. Distance pointers never point before the beginning of the output - stream. - 2. Distance pointers can point back across blocks, up to 32k away. - 3. There is an implied maximum of 7 bits for the bit length table and - 15 bits for the actual data. - 4. If only one code exists, then it is encoded using one bit. (Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarly, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12. Note: length code 284 can represent 227-258, but length code 285 - really is 258. The last length deserves its own, short code - since it gets used a lot in very redundant files. The length - 258 is special since 258 - 3 (the min match length) is 255. - 13. The literal/length and distance code bit lengths are read as a - single stream of lengths. It is possible (and advantageous) for - a repeat code (16, 17, or 18) to go across the boundary between - the two sets of lengths. - */ - - -#define PKZIP_BUG_WORKAROUND /* PKZIP 1.93a problem--live with it */ - -/* - inflate.h must supply the uch slide[GZ_WSIZE] array and the NEXTBYTE, - FLUSH() and memzero macros.

Stated another way, * no other mutex may be held when Giant is acquired. * * 2) Giant must be released when blocking on a sleepable lock. * * This rule is less obvious, but is a result of Giant providing the same * semantics as spl(). Basically, when a thread sleeps, it must release * Giant. When a thread blocks on a sleepable lock, it sleeps. Hence rule * 2). * * 3) Giant may be acquired before or after sleepable locks. * * This rule is also not quite as obvious. Giant may be acquired after * a sleepable lock because it is a non-sleepable lock and non-sleepable * locks may always be acquired while holding a sleepable lock. The second * case, Giant before a sleepable lock, follows from rule 2) above. Suppose * you have two threads T1 and T2 and a sleepable lock X. Suppose that T1 * acquires X and blocks on Giant. Then suppose that T2 acquires Giant and * blocks on X. When T2 blocks on X, T2 will release Giant allowing T1 to * execute. Thus, acquiring Giant both before and after a sleepable lock * will not result in a lock order reversal. */ #include __FBSDID("$FreeBSD$"); #include "opt_ddb.h" #include "opt_hwpmc_hooks.h" #include "opt_stack.h" #include "opt_witness.h" #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #ifdef DDB #include #endif #include #if !defined(DDB) && !defined(STACK) #error "DDB or STACK options are required for WITNESS" #endif /* Note that these traces do not work with KTR_ALQ. */ #if 0 #define KTR_WITNESS KTR_SUBSYS #else #define KTR_WITNESS 0 #endif #define LI_RECURSEMASK 0x0000ffff /* Recursion depth of lock instance. */ #define LI_EXCLUSIVE 0x00010000 /* Exclusive lock instance. */ #define LI_NORELEASE 0x00020000 /* Lock not allowed to be released. */ -/* Define this to check for blessed mutexes */ -#undef BLESSING - #ifndef WITNESS_COUNT #define WITNESS_COUNT 1536 #endif #define WITNESS_HASH_SIZE 251 /* Prime, gives load factor < 2 */ #define WITNESS_PENDLIST (512 + (MAXCPU * 4)) /* Allocate 256 KB of stack data space */ #define WITNESS_LO_DATA_COUNT 2048 /* Prime, gives load factor of ~2 at full load */ #define WITNESS_LO_HASH_SIZE 1021 /* * XXX: This is somewhat bogus, as we assume here that at most 2048 threads * will hold LOCK_NCHILDREN locks.

Each structure * is an element of several collections: * * A radix tree used to quickly * perform object/offset lookups * * A list of all pages for a given object, * so they can be quickly deactivated at * time of deallocation. * * An ordered list of pages due for pageout. * * In addition, the structure contains the object * and offset to which this page belongs (for pageout), * and sundry status bits. * * In general, operations on this structure's mutable fields are * synchronized using either one of or a combination of the lock on the * object that the page belongs to (O), the page lock (P), * the per-domain lock for the free queues (F), or the page's queue * lock (Q). The physical address of a page is used to select its page * lock from a pool. The queue lock for a page depends on the value of * its queue field and described in detail below. If a field is * annotated below with two of these locks, then holding either lock is * sufficient for read access, but both locks are required for write * access. An annotation of (C) indicates that the field is immutable. * * In contrast, the synchronization of accesses to the page's * dirty field is machine dependent (M). In the * machine-independent layer, the lock on the object that the * page belongs to must be held in order to operate on the field. * However, the pmap layer is permitted to set all bits within * the field without holding that lock. If the underlying * architecture does not support atomic read-modify-write * operations on the field's type, then the machine-independent * layer uses a 32-bit atomic on the aligned 32-bit word that * contains the dirty field. In the machine-independent layer, * the implementation of read-modify-write operations on the * field is encapsulated in vm_page_clear_dirty_mask(). * * The page structure contains two counters which prevent page reuse. * Both counters are protected by the page lock (P). The hold * counter counts transient references obtained via a pmap lookup, and * is also used to prevent page reclamation in situations where it is * undesirable to block other accesses to the page. The wire counter * is used to implement mlock(2) and is non-zero for pages containing * kernel memory. Pages that are wired or held will not be reclaimed * or laundered by the page daemon, but are treated differently during * a page queue scan: held pages remain at their position in the queue, * while wired pages are removed from the queue and must later be * re-enqueued appropriately by the unwiring thread. It is legal to * call vm_page_free() on a held page; doing so causes it to be removed * from its object and page queue, and the page is released to the * allocator once the last hold reference is dropped. In contrast, * wired pages may not be freed. * * In some pmap implementations, the wire count of a page table page is * used to track the number of populated entries. * * The busy lock is an embedded reader-writer lock which protects the * page's contents and identity (i.e., its tuple) and * interlocks with the object lock (O). In particular, a page may be * busied or unbusied only with the object write lock held. To avoid * bloating the page structure, the busy lock lacks some of the * features available to the kernel's general-purpose synchronization * primitives. As a result, busy lock ordering rules are not verified, * lock recursion is not detected, and an attempt to xbusy a busy page * or sbusy an xbusy page results will trigger a panic rather than * causing the thread to block. vm_page_sleep_if_busy() can be used to * sleep until the page's busy state changes, after which the caller * must re-lookup the page and re-evaluate its state. * * The queue field is the index of the page queue containing the * page, or PQ_NONE if the page is not enqueued. The queue lock of a * page is the page queue lock corresponding to the page queue index, * or the page lock (P) for the page if it is not enqueued. To modify * the queue field, the queue lock for the old value of the field must * be held. It is invalid for a page's queue field to transition * between two distinct page queue indices. That is, when updating * the queue field, either the new value or the old value must be * PQ_NONE. * * To avoid contention on page queue locks, page queue operations * (enqueue, dequeue, requeue) are batched using per-CPU queues. * A deferred operation is requested by inserting an entry into a * batch queue; the entry is simply a pointer to the page, and the * request type is encoded in the page's aflags field using the values * in PGA_QUEUE_STATE_MASK. The type-stability of struct vm_pages is * crucial to this scheme since the processing of entries in a given * batch queue may be deferred indefinitely. In particular, a page * may be freed before its pending batch queue entries have been * processed. The page lock (P) must be held to schedule a batched * queue operation, and the page queue lock must be held in order to * process batch queue entries for the page queue. */ #if PAGE_SIZE == 4096 #define VM_PAGE_BITS_ALL 0xffu typedef uint8_t vm_page_bits_t; #elif PAGE_SIZE == 8192 #define VM_PAGE_BITS_ALL 0xffffu typedef uint16_t vm_page_bits_t; #elif PAGE_SIZE == 16384 #define VM_PAGE_BITS_ALL 0xffffffffu typedef uint32_t vm_page_bits_t; #elif PAGE_SIZE == 32768 #define VM_PAGE_BITS_ALL 0xfffffffffffffffflu typedef uint64_t vm_page_bits_t; #endif struct vm_page { union { TAILQ_ENTRY(vm_page) q; /* page queue or free list (Q) */ struct { SLIST_ENTRY(vm_page) ss; /* private slists */ void *pv; } s; struct { u_long p; u_long v; } memguard; } plinks; TAILQ_ENTRY(vm_page) listq; /* pages in same object (O) */ vm_object_t object; /* which object am I in (O,P) */ vm_pindex_t pindex; /* offset into object (O,P) */ vm_paddr_t phys_addr; /* physical address of page (C) */ struct md_page md; /* machine dependent stuff */ u_int wire_count; /* wired down maps refs (P) */ volatile u_int busy_lock; /* busy owners lock */ uint16_t flags; /* page PG_* flags (P) */ uint8_t order; /* index of the buddy queue (F) */ uint8_t pool; /* vm_phys freepool index (F) */ uint8_t aflags; /* access is atomic */ uint8_t oflags; /* page VPO_* flags (O) */ uint8_t queue; /* page queue index (Q) */ int8_t psind; /* pagesizes[] index (O) */ int8_t segind; /* vm_phys segment index (C) */ u_char act_count; /* page usage count (P) */ /* NOTE that these must support one bit per DEV_BSIZE in a page */ /* so, on normal X86 kernels, they must be at least 8 bits wide */ vm_page_bits_t valid; /* map of valid DEV_BSIZE chunks (O) */ vm_page_bits_t dirty; /* map of dirty DEV_BSIZE chunks (M) */ }; /* * Page flags stored in oflags: * * Access to these page flags is synchronized by the lock on the object * containing the page (O). * * Note: VPO_UNMANAGED (used by OBJT_DEVICE, OBJT_PHYS and OBJT_SG) * indicates that the page is not under PV management but * otherwise should be treated as a normal page.
