The instrumentation, when enabled, causes +** each call to the instrumented function to record data about +** the call to an external file. The external file +** subsequently used to extract performance data and other +** statistical information about the operation of locks used in +** the nss library. +** +** To enable compilation with instrumentation, build NSS with +** the compile time switch NEED_NSS_ILOCK defined. +** +** say: "gmake OS_CFLAGS+=-DNEED_NSS_ILOCK" at make time. +** +** At runtime, to enable recording from nssilock, one or more +** environment variables must be set. For each nssILockType to +** be recorded, an environment variable of the form NSS_ILOCK_x +** must be set to 1. For example: +** +** set NSS_ILOCK_Cert=1 +** +** nssilock uses PRLOG is used to record to trace data. The +** PRLogModule name associated with nssilock data is: "nssilock". +** To enable recording of nssilock data you will need to set the +** environment variable NSPR_LOG_MODULES to enable +** recording for the nssilock log module. Similarly, you will +** need to set the environment variable NSPR_LOG_FILE to specify +** the filename to receive the recorded data. See prlog.h for usage. +** Example: +** +** export NSPR_LOG_MODULES=nssilock:6 +** export NSPR_LOG_FILE=xxxLogfile +** +** Operation: +** nssilock wraps calls to NSPR's PZLock and PZMonitor functions +** with similarly named functions: PZ_NewLock(), etc. When NSS is +** built with lock instrumentation enabled, the PZ* functions are +** compiled into NSS; when lock instrumentation is disabled, +** calls to PZ* functions are directly mapped to PR* functions +** and the instrumentation arguments to the PZ* functions are +** compiled away. +** +** +** File Format: +** The format of the external file is implementation +** dependent. Where NSPR's PR_LOG() function is used, the file +** contains data defined for PR_LOG() plus the data written by +** the wrapped function. On some platforms and under some +** circumstances, platform dependent logging or +** instrumentation probes may be used. In any case, the +** relevant data provided by the lock instrumentation is: +** +** lockType, func, address, duration, line, file [heldTime] +** +** where: +** +** lockType: a character representation of nssILockType for the +** call. e.g. ... "cert" +** +** func: the function doing the tracing. e.g. "NewLock" +** +** address: address of the instrumented lock or monitor +** +** duration: is how long was spent in the instrumented function, +** in PRIntervalTime "ticks". +** +** line: the line number within the calling function +** +** file: the file from which the call was made +** +** heldTime: how long the lock/monitor was held. field +** present only for PZ_Unlock() and PZ_ExitMonitor(). +** +** Design Notes: +** The design for lock instrumentation was influenced by the +** need to gather performance data on NSS 3.x. It is intended +** that the effort to modify NSS to use lock instrumentation +** be minimized. Existing calls to locking functions need only +** have their names changed to the instrumentation function +** names. +** +** Private NSS Interface: +** nssilock.h defines a private interface for use by NSS. +** nssilock.h is experimental in nature and is subject to +** change or revocation without notice. ...

Similarly, you will +** need to set the environment variable NSPR_LOG_FILE to specify +** the filename to receive the recorded data. See prlog.h for usage. +** Example: +** +** export NSPR_LOG_MODULES=nssilock:6 +** export NSPR_LOG_FILE=xxxLogfile +** +** Operation: +** nssilock wraps calls to NSPR's PZLock and PZMonitor functions +** with similarly named functions: PZ_NewLock(), etc. When NSS is +** built with lock instrumentation enabled, the PZ* functions are +** compiled into NSS; when lock instrumentation is disabled, +** calls to PZ* functions are directly mapped to PR* functions +** and the instrumentation arguments to the PZ* functions are +** compiled away. +** +** +** File Format: +** The format of the external file is implementation +** dependent. Where NSPR's PR_LOG() function is used, the file +** contains data defined for PR_LOG() plus the data written by +** the wrapped function. On some platforms and under some +** circumstances, platform dependent logging or +** instrumentation probes may be used. In any case, the +** relevant data provided by the lock instrumentation is: +** +** lockType, func, address, duration, line, file [heldTime] +** +** where: +** +** lockType: a character representation of nssILockType for the +** call. e.g. ... "cert" +** +** func: the function doing the tracing. e.g. "NewLock" +** +** address: address of the instrumented lock or monitor +** +** duration: is how long was spent in the instrumented function, +** in PRIntervalTime "ticks". +** +** line: the line number within the calling function +** +** file: the file from which the call was made +** +** heldTime: how long the lock/monitor was held. field +** present only for PZ_Unlock() and PZ_ExitMonitor(). +** +** Design Notes: +** The design for lock instrumentation was influenced by the +** need to gather performance data on NSS 3.x. It is intended +** that the effort to modify NSS to use lock instrumentation +** be minimized. Existing calls to locking functions need only +** have their names changed to the instrumentation function +** names. +** +** Private NSS Interface: +** nssilock.h defines a private interface for use by NSS. +** nssilock.h is experimental in nature and is subject to +** change or revocation without notice. ...

For + * brevity, these will be referred to as 'string' and 'any' types. + * + * This leads to the following possibilities: + * 1: This element is an indefinite length string, part of a + * definite length string. + * 2: This element is an indefinite length string, part of an + * indefinite length string. + * 3: This element is an indefinite length any, part of a + * definite length any. + * 4: This element is an indefinite length any, part of an + * indefinite length any. + * 5: This element is an indefinite length any and does not + * meet any of the above criteria. Note that this would include + * an indefinite length string type matching an indefinite + * length any template. + * + * In Cases #1 and #3, the definite length 'parent' element will + * have allocated state->dest based on the parent elements definite + * size. During the processing of 'child', sec_asn1d_parse_leaf will + * have copied the (string, any) data directly into the offset of + * dest, as appropriate, so there's no need for this class to still + * store the child - it's already been processed. + * + * In Cases #2 and #4, dest will be set to the parent element's dest, + * but dest->data will not have been allocated yet, due to the + * indefinite length encoding. In this situation, it's necessary to + * hold onto child (and all other children) until the EOC, at which + * point, it becomes possible to compute 'state's overall length. Once + * 'state' has a computed length, this can then be fed to 'parent' (via + * this state), and then 'parent' can similarly compute the length of + * all of its children up to the EOC, which will ultimately transit to + * sec_asn1d_concat_substrings, determine the overall size needed, + * allocate, and copy the contents (of all of parent's children, which + * would include 'state', just as 'state' will have copied all of its + * children via sec_asn1d_concat_substrings) + * + * The final case, Case #5, will manifest in that item->data and + * item->len will be NULL/0, respectively, since this element was + * indefinite-length encoded.

The memory in them consists of large blocks, + * called arenas, which are allocated from the/a system heap. Inside an + * ArenaPool, the arenas are organized as if they were in a stack. Newly + * allocated arenas are "pushed" on that stack. When you attempt to + * allocate memory from an ArenaPool, the code first looks to see if there + * is enough unused space in the top arena on the stack to satisfy your + * request, and if so, your request is satisfied from that arena. + * Otherwise, a new arena is allocated (or taken from NSPR's list of freed + * arenas) and pushed on to the stack. The new arena is always big enough + * to satisfy the request, and is also at least a minimum size that is + * established at the time that the ArenaPool is created. + * + * The ArenaMark function returns the address of a marker in the arena at + * the top of the arena stack. It is the address of the place in the arena + * on the top of the arena stack from which the next block of memory will + * be allocated. Each ArenaPool has its own separate stack, and hence + * marks are only relevant to the ArenaPool from which they are gotten. + * Marks may be nested. That is, a thread can get a mark, and then get + * another mark. + * + * It is intended that all the marks in an ArenaPool may only be owned by a + * single thread. In DEBUG builds, this is enforced. In non-DEBUG builds, + * it is not. In DEBUG builds, when a thread gets a mark from an + * ArenaPool, no other thread may acquire a mark in that ArenaPool while + * that mark exists, that is, until that mark is unmarked or released. + * Therefore, it is important that every mark be unmarked or released when + * the creating thread has no further need for exclusive ownership of the + * right to manage the ArenaPool. + * + * The ArenaUnmark function discards the ArenaMark at the address given, + * and all marks nested inside that mark (that is, acquired from that same + * ArenaPool while that mark existed). It is an error for a thread other + * than the mark's creator to try to unmark it. When a thread has unmarked + * all its marks from an ArenaPool, then another thread is able to set + * marks in that ArenaPool. ArenaUnmark does not deallocate (or "pop") any + * memory allocated from the ArenaPool since the mark was created. + * + * ArenaRelease "pops" the stack back to the mark, deallocating all the + * memory allocated from the arenas in the ArenaPool since that mark was + * created, and removing any arenas from the ArenaPool that have no + * remaining active allocations when that is done. It implicitly releases + * any marks nested inside the mark being explicitly released. It is the + * only operation, other than destroying the arenapool, that potentially + * reduces the number of arenas on the stack. Otherwise, the stack grows + * until the arenapool is destroyed, at which point all the arenas are + * freed or returned to a "free arena list", depending on their sizes. + */ +PLArenaPool * +PORT_NewArena(unsigned long chunksize) +{ + PORTArenaPool *pool; + + if (chunksize > MAX_SIZE) { + PORT_SetError(SEC_ERROR_NO_MEMORY); + return NULL; + } + pool = PORT_ZNew(PORTArenaPool); + if (!pool) { + return NULL; + } + pool->magic = ARENAPOOL_MAGIC; + pool->lock = PZ_NewLock(nssILockArena); + if (!pool->lock) { + PORT_Free(pool); + return NULL; + } + PL_InitArenaPool(&pool->arena, "security", chunksize, sizeof(double)); + return (&pool->arena); +} + +void +PORT_InitCheapArena(PORTCheapArenaPool *pool, unsigned long chunksize) +{ + pool->magic = CHEAP_ARENAPOOL_MAGIC; + PL_InitArenaPool(&pool->arena, "security", chunksize, sizeof(double)); +} + +void * +PORT_ArenaAlloc(PLArenaPool *arena, size_t size) +{ + void *p = NULL; + + PORTArenaPool *pool = (PORTArenaPool *)arena; + + if (size <= 0) { + size = 1; + } + + if (size > MAX_SIZE) { + /* you lose. */ + } else + /* Is it one of ours?
