* Implement x86 ptrace(2) requests PT_{GET,SET}{FS,GS}BASE.kib2015-08-051-2/+189
| | | | | | | | | | | | | | | | | | | | | | MFC r284918: Add helper fill_based_sd(9). MFC r284919: Add x86 PT_GETFSBASE, PT_GETGSBASE machine-depended ptrace requests to obtain the thread %fs and %gs bases. Add x86 PT_SETFSBASE and PT_SETGSBASE requests to set the bases from debuggers. The set requests, similarly to the sysarch({I386,AMD64}_SET_FSBASE), override the corresponding segment registers. MFC r284965: Document x86 machine-specific ptrace(2) requests. MFC r285011: Disallow a debugger on 64bit system to set fs/gs bases of the 32bit process beyond the end of the process address space. MFC r285104: Grammar and language fixes.

| | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | Tweak seekdir, telldir and readdir so that when htere are deletes going on, as seek to teh last location saved will still work. This is needed for Samba to be able to correctly handle delete requests from windows. This does not completely fix seekdir when deletes are present but fixes the worst of the problems. The real solution must involve some changes to the API for eh VFS and getdirentries(2). Obtained from: Panzura inc MFH: r282550 (jhb@) A few style fixes and expand the comment a bit on what _fixtelldir() is doing. MFH: r282560 (jhb@) Tweak the comment here some more.

* MFC r280919: wordexp: Explicitly pass along IFS.jilles2015-04-191-1/+4
| | | | | | | | | Per Austin group issue #884, sh should not import IFS from the environment but always set it to $' \t\n'. For wordexp(), however, it is documented and useful for it to use IFS from the environment. Since sh currently imports IFS from the environment, this change has no functional effect.
* MFC r281082: fts: Don't return FTS_SLNONE if it's not a symlink (if race).jilles2015-04-191-5/+6
| | | | | | | | | | | | | | When following symlinks, fts returned FTS_SLNONE when fstatat(flag=0) failed, but a subsequent fstatat(flag=AT_SYMLINK_NOFOLLOW) succeeded. This incorrectly triggered if a filename existed to be read from the directory, was deleted before the fstatat(flag=0) and created again after the fstatat(flag=0). Fix this by only returning FTS_SLNONE if the result from fstatat(flag=AT_SYMLINK_NOFOLLOW) is actually a symlink. If it is not a symlink, treat it as if fstatat(flag=0) succeeded. PR: 196724

* MFC r260571: fts: Stat things relative to the directory fd, if possible.jilles2015-04-181-12/+19
| | | | | | | | | As a result, the kernel needs to process shorter pathnames if fts is not changing directories (if fts follows symlinks (-L option to utilities), fts cannot open "." or FTS_NOCHDIR was specified). Side effect: If pathnames exceed PATH_MAX, [ENAMETOOLONG] is not hit at the stat stage but later (opendir or application fts_accpath) or not at all.

| | | | | | | | 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.
