| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix error reporting from wcstof() When wcstof() skipped initial space and then parsing failed, it set endptr to the first non-space character. Fix it to correctly report failure by setting endptr to the beginning of the input string. The fix is from theraven@, who fixed this bug in wcstod() and wcstold() in r227753. While I'm here: Move assignments out of declarations in wcstod() and wcstold(). This is against my personal preference, but it is our agreed style(9). Set endptr correctly on malloc() failure in all three functions. Remove an incorrect comment: This is pointer arithmetic, so the code was not actually making that assumption. wcstold() advanced the wcp pointer beyond leading whitespace and then reset it back to the beginning of the string. Do not reset it. This seems to have no functional effect, since strtold_l() also skips leading whitespace. I'm making the change to keep this function consistent with wcstof() and wcstod(), and because the C11 spec prescribes the use of iswspace() to skip leading space.

* MFC r305154: directory(3): Deprecate readdir_r(). Clarify dirent buffers.Jilles Tjoelker2016-09-071-2/+24
| | | | | | | | | | | | | | | | | | In existing implementations including FreeBSD, there is no reason to use readdir_r() in the common case where potentially multiple threads each list their own directory. Code using readdir() is simpler. What's more, although readdir_r() can safely be used on FreeBSD because NAME_MAX is forced to 255, it cannot be used safely on systems where {NAME_MAX} is not fixed. As a concrete example, FAT/NTFS filenames can be up to 255 UTF-16 code units long, which can be up to 765 UTF-8 bytes. Deprecating readdir_r() in POSIX has been proposed in http://www.austingroupbugs.net/view.php?id=696 and glibc wants to deprecate it as well. Notes: svn path=/stable/10/; revision=305569

| | | | | | | | | | | | | | | | The formal behavior of qsort is unstable with regard to objects that are equal. Unfortunately, RFC 3484 requires that otherwise equal objects remain in the order supplied by the DNS server. The present code attempts to deal with this by returning -1 for objects that are equal (i.e., returns that the first parameter is less then the second parameter). Unfortunately, the qsort API does not state that the first parameter passed in is in any particular position in the list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 1) _locale.h LC_*_MASK bit shifting order was partially broken from the initial commit time at year 2012. Only LC_COLLATE_MASK and LC_CTYPE_MASK are in the right order. The order here should match XLC_* from "xlocale_private.h" which, in turn, match LC_* publicly visible order from <locale.h> which determines how locale components are stored in the structure. LC_*_MASK -> XLC_* translation done as "ffs(mask) - 1" in the querylocale() and equivalent shift loop in the newlocale(), so mapped to some wrong components (excluding two mentioned above). Formally the fix is ABI breakage, but old code using those masks never works properly in any case. Only newlocale() and querylocale() are affected. 2) msgcat.c Use current locale (f.e. set by thread). It was global locale always previously. PR: 211743 Notes: svn path=/stable/10/; revision=304862

* MFC 304476: Fix various nits in the aio operation manpages.John Baldwin2016-08-224-26/+15
| | | | | | | | | | | | | | | | | | | | | - Avoid double use of "request" in a single sentence. Instead, describe aio_sigevent as being used to request notification of the associated operation's completion. This matches the language used to describe aio_sigevent in aio(4). - Simplify the prohibition on modifying buffers while requests are in flight. - Fix case mismatch. - Drop note about not using stack variables. C programmers should be able to figure out if a stack variable is safe based on the later warning about the life cycle requirements of control blocks. - Remove prohibition on modifying the I/O buffer for aio_fsync() since it does not use an I/O buffer. For aio_mlock(), prohibit modifications to the mapping (e.g. due to mprotect, munmap, mmap, etc.) but do not prohibit modifications to the memory backing the buffer (stores into the pages backing the buffer).

Including subcases: Both C99 and POSIX directly prohibits any standard function to set errno to 0. Breaking this rule in 2001 NetBSD hack was imported which attempts to workaround very limited glob(3) return codes amount. Use POSIX-compatible workaround now with E2BIG which can't comes from other functions used instead of prohibited 0. Process errors happpens in (*readdirfunc)() too, as POSIX requires. Per POSIX GLOB_NOCHECK should return original pattern, unmodified, if no matches found. But our code strips all '\' returning it. Rewrite the code to allow to return original pattern. GLOB_ERR and gl_errfunc are supposed to work only for real directories per POSIX, so don't act on missing or plain files for ENOENT or ENOTDIR (as TODO in the code suggested). Remove the hack in the manpage describing how to skip ENOENT and ENOTDIR in gl_errfunc, it is unneeded now. Per POSIX GLOB_ERR must be considered even if gl_errfunc is not set, old code skips it in that case. 2) For near MAXPATHLEN long pathes old glob(3) code can operate on truncated results, prevent it in several places. 3) Results was not sorted according to collate as POSIX requires. 4) globtilde() forget to convert expanded user home dir from multibyte to wide chars. Moreover, those chars are addded as not protected, so can be treated as special chars. 5) Backward hack for EILSEQ in g_Ctoc() was not implemented, so all pathes with illegal byte sequences are skipped as result, implement it now. 6) GLOB_BRACE was somehow broken. First it repeatedly calls glob0() in globexp1() recursive calls, but glob0() was not supposed to be called repeatedly in the original code. It finalize results by possible adding original pattern for no match case, may return GLOB_NOMATCH error and by sorting all things. Original pattern adding or GLOB_NOMATCH error can happens each time glob0() called repeatedly, and sorting happens for one item only, all things are never sorted. Second, f.e. "a{a" pattern does not match "a{a" file but match "a" file instead. Third, some errors (f.e. for limits or overflow) can be ignored by GLOB_BRACE code because it forces return (0). Add non-finalizing flag to glob0() and make globexp0() wrapper around recursively called globexp1() to finalize things like glob0() does. Reorganize braces code to work correctly. 7) Don't allow MB_CUR_MAX * strlen overallocation hits GLOB_LIMIT_STRING (ARG_MAX) limit, use final string length, not malloced space for it.

This test verifies we get the correct ptrace event details when a signal is posted to a traced process from userland. 302902: Add a mask of optional ptrace() events. ptrace() now stores a mask of optional events in p_ptevents. Currently this mask is a single integer, but it can be expanded into an array of integers in the future. Two new ptrace requests can be used to manipulate the event mask: PT_GET_EVENT_MASK fetches the current event mask and PT_SET_EVENT_MASK sets the current event mask. The current set of events include: - PTRACE_EXEC: trace calls to execve(). - PTRACE_SCE: trace system call entries. - PTRACE_SCX: trace syscam call exits. - PTRACE_FORK: trace forks and auto-attach to new child processes. - PTRACE_LWP: trace LWP events. The S_PT_SCX and S_PT_SCE events in the procfs p_stops flags have been replaced by PTRACE_SCE and PTRACE_SCX. PTRACE_FORK replaces P_FOLLOW_FORK and PTRACE_LWP replaces P2_LWP_EVENTS. The PT_FOLLOW_FORK and PT_LWP_EVENTS ptrace requests remain for compatibility but now simply toggle corresponding flags in the event mask. While here, document that PT_SYSCALL, PT_TO_SCE, and PT_TO_SCX both modify the event mask and continue the traced process. 302921: Rename PTRACE_SYSCALL to LINUX_PTRACE_SYSCALL. 303461: Note that not all optional ptrace events use SIGTRAP.

In previous state only first 256 wide chars are considered and all others are just silently dropped from the range. Notes: svn path=/stable/10/; revision=303185
