| | | | | | | | | | | | | | | | | | | Various updates to the ftruncate(2) documentation: - Note that ftruncate(2) can operate on shared memory objects and cross reference shm_open(2). - Note that ftruncate(2) does not change the file position pointer (aka seek pointer) of the file descriptor. - ftruncate(2) will fail with EINVAL for all sorts of other fd types than just sockets, so instead note that it fails for all but regular files and shared memory objects. - Note that ftruncate(2) also appeared in 4.2BSD along with truncate(2). (Or at least the manpage for both appeared in 4.2, I did not check the kernel code itself to see if either predated 4.2.) PR: 199472 Notes: svn path=/stable/8/; revision=283916

| | | | | | | | | | | When catopen(3) returns an error, it caches the result of that error from r202992. The refcount on the cache entry is not initialized, so any attempt to clean the cache will skip over this item since it likely has a >0 value. This change is currently a NOP.

| | | | | | | | | | | | | | | | | | | | | | r227519 (das) Sync the style, comments, and variable names of arc4random.c with OpenBSD's version (r1.22). No functional changes, as verified with md5. r227520 (das) Further reduce diffs with OpenBSD's arc4random. The main functional change here is to ensure that when a process forks after arc4random is seeded, the parent and child don't observe the same random sequence. OpenBSD's fix introduces some additional overhead in the form of a getpid() call. The only significant remaining difference between our arc4random and OpenBSD's is in how we seed the generator in arc4_stir(). Notes: svn path=/stable/8/; revision=267380

If NOTE_FORK is set, the listener will get a NOTE_FORK event from the parent pid, but not a separate NOTE_TRACK event. - Explicitly note that the event added to monitor the child process preserves the fflags from the original event. - Move the description of NOTE_TRACKERR under NOTE_TRACK as it is not a bit for the user to set (which is what this list pupports to be). Also, explicitly note that if an error occurs, the NOTE_CHILD event will not be generated. Notes: svn path=/stable/8/; revision=257717

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Protect against DoS attacks, such as being described in CVE-2010-2632. The changes were derived from what has been committed to NetBSD, with modifications. These are: 1. Preserve the existsing GLOB_LIMIT behaviour by including the number of matches to the set of parameters to limit. 2. Change some of the limits to avoid impacting normal use cases: GLOB_LIMIT_STRING - change from 65536 to ARG_MAX so that glob(3) can still provide a full command line of expanded names. GLOB_LIMIT_STAT - change from 128 to 1024 for no other reason than that 128 feels too low (it's not a limit that impacts the behaviour of the test program listed in CVE-2010-2632). GLOB_LIMIT_PATH - change from 1024 to 65536 so that glob(3) can still provide a fill command line of expanded names. 3. Protect against buffer overruns when we hit the GLOB_LIMIT_STAT or GLOB_LIMIT_READDIR limits. We append SEP and EOS to pathend in those cases. Return GLOB_ABORTED instead of GLOB_NOSPACE when we would otherwise overrun the buffer. This change also modifies the existing behaviour of glob(3) in case GLOB_LIMIT is specifies by limiting the *new* matches and not all matches. This is an important distinction when GLOB_APPEND is set or when the caller uses a non-zero gl_offs. Previously pre-existing matches or the value of gl_offs would be counted in the number of matches even though the man page states that glob(3) would return GLOB_NOSPACE when gl_matchc or more matches were found. The limits that cannot be circumvented are GLOB_LIMIT_STRING and GLOB_LIMIT_PATH all others can be crossed by simply calling glob(3) again and with GLOB_APPEND set. The entire description above applies only when GLOB_LIMIT has been specified of course. No limits apply when this flag isn't set!

* MFC r243758 (marcel):Xin LI2013-02-051-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | In globextend() when the pathv vector cannot be (re-)allocated, don't free and clear the gl_pathv pointer in the glob_t structure. Such breaks the invariant of the glob_t structure, as stated in the comment right in front of the globextend() function. If gl_pathv was non-NULL, then gl_pathc was > 0. Making gl_pathv a NULL pointer without also setting gl_pathc to 0 is wrong. Since we otherwise don't free the memory associated with a glob_t in error cases, it's unlikely that this change will cause a memory leak that wasn't already there to begin with. Callers of glob(3) must call globfree(3) irrespective of whether glob(3) returned an error or not. MFC r243759 (marcel): In globextend(), take advantage of the fact that realloc(NULL, size) is equivalent to malloc(size). This eliminates the conditional expression used for calling either realloc() or malloc() when realloc() will do all the time. Notes: svn path=/stable/8/; revision=246356
