-Subject: [PATCH] handle non-matching address family entries in hosts file
-
-name_from_hosts failed to account for the possibility of an address
-family error from name_from_numeric, wrongly counting such a return as
-success and using the uninitialized address data as part of the
-results passed up to the caller.
-
-non-matching address family entries cannot simply be ignored or
-results would be inconsistent with respect to whether AF_UNSPEC or a
-specific address family is queried. instead, record that a
-non-matching entry was seen, and fail the lookup with EAI_NONAME of no
-matching-family entries are found.

-
-This is a workaround to treat * as literal * at the start of a BRE.
-
-Ideally ^ would be treated as an anchor at the start of any BRE
-subexpression and similarly $ would be an anchor at the end of any
-subexpression.  This is not required by the standard and hard to do
-with the current code, but it's the existing practice.  If it is
-changed, * should be treated as literal after such anchor as well.

-Subject: [PATCH] fix padding string formats to width in wide printf variants
-
-the idiom fprintf(f, "%.*s", n, "") was wrongly used in vfwprintf as a
-means of producing n spaces; instead it produces no output. the
-correct form is fprintf(f, "%*s", n, ""), using width instead of
-precision, since for %s the later is a maximum rather than a minimum.

-Subject: [PATCH] fix undefined pointer comparison in stdio-internal __toread
-
-the comparison f->wpos > f->buf has undefined behavior when f->wpos is
-a null pointer, despite the intuition (and actual compiler behavior,
-for all known compilers) being that NULL > ptr is false for all valid
-pointers ptr.
-
-the purpose of the comparison is to determine if the write buffer is
-non-empty, and the idiom used elsewhere for that is comparison against
-f->wbase, which is either a null pointer when not writing, or equal to
-f->buf when writing. in the former case, both f->wpos and f->wbase are
-null; in the latter they are both non-null and point into the same
-array.

-Subject: [PATCH] fix read past end of haystack buffer for short needles in
- memmem
-
-the two/three/four byte memmem specializations are not prepared to
-handle haystacks shorter than the needle; they unconditionally read at
-least up to the needle length and subtract from the haystack length.
-if the haystack is shorter, the remaining haystack length underflows
-and produces an unbounded search which will eventually either crash or
-find a spurious match.
-
-the top-level memmem function attempted to avoid this case already by
-checking for haystack shorter than needle, but it failed to re-check
-after using memchr to remove the maximal prefix not containing the
-first byte of the needle.

-Subject: [PATCH] fix FILE buffer underflow in ungetwc
-
-commit 7e816a6487932cbb3cb71d94b609e50e81f4e5bf (version 1.1.11
-release cycle) moved the code that performs wchar_t to multibyte
-conversion across code that used the resulting length in bytes,
-thereby breaking the unget buffer space check in ungetwc and
-clobbering up to three bytes below the start of the buffer.
-
-for allocated FILEs (all read-enabled FILEs except stdin), the
-underflow clobbers at most the FILE-specific locale pointer. no stores
-are performed through this pointer, but subsequent loads may result in
-a crash or mismatching encoding rule (UTF-8 multibyte vs byte-based).
-
-for stdin, the buffer lies in .bss and the underflow may clobber
-another object. in practice, for libc.so the adjacent object seems to
-be stderr's buffer, which is completely unused, but this could vary
-with linking options, or when static linking.
-
-applications which do not attempt to use more than one character of
-ungetwc pushback, or which do not use ungetwc, are not affected.

-previously if you called getprotobyname("egp") you would get
-NULL because \008 is invalid octal and so the protocol id was

-    fix failure to obtain EOWNERDEAD status for process-shared robust mutexes
-    
-    Linux's documentation (robust-futex-ABI.txt) claims that, when a
-    process dies with a futex on the robust list, bit 30 (0x40000000) is
-    set to indicate the status. however, what actually happens is that
-    bits 0-30 are replaced with the value 0x40000000, i.e. bits 0-29
-    (containing the old owner tid) are cleared at the same time bit 30 is
-    set.
-    
-    our userspace-side code for robust mutexes was written based on that
-    documentation, assuming that kernel would never produce a futex value
-    of 0x40000000, since the low (owner) bits would always be non-zero.
-    commit d338b506e39b1e2c68366b12be90704c635602ce introduced this
-    assumption explicitly while fixing another bug in how non-recoverable
-    status for robust mutexes was tracked. presumably the tests conducted
-    at that time only checked non-process-shared robust mutexes, which are
-    handled in pthread_exit (which implemented the documented kernel
-    protocol, not the actual one) rather than by the kernel.
-    
-    change pthread_exit robust list processing to match the kernel
-    behavior, clearing bits 0-29 while setting bit 30, and use the value
-    0x7fffffff instead of 0x40000000 to encode non-recoverable status. the
-    choice of value here is arbitrary; any value with at least one of bits
-    0-29 set should work just as well,
