We use sourceware.org consistently to reference the
server that RedHat provides for community services
to open-source projects.
[BZ # 13963]
* manual/install.texi: Use sourceware.org.
The proper define to check "am I in a shared lib" is "SHARED", not "PIC".
The two new memset_chk functions incorrectly depend on "PIC".

Compiling on Linux/i586 I get these warnings:
nss_db/db-initgroups.c:60:3: warning: implicit declaration of function
'strlen' [-Wimplicit-function-declaration]
nss_db/db-initgroups.c:74:7: warning: implicit declaration of function
'strncmp' [-Wimplicit-function-declaration]
Fixed with inclusion of <string.h>
* elf/rtld.c (dl_main): If DL_DEBUG_UNUSED is enabled, turn off
lazy binding.
* elf/dl-lookup (_dl_lookup_symbol_x): If DL_DEBUG_UNUSED, ignore
undefined symbol errors.
* elf/rtlc.c (dl_main): Skip VDSO when checking for unused
DT_NEEDED entries.

There are several signed compares of the size argument, whereas
it really is unsigned. Depending on situations e.g. a "memset(ptr, 0,
-1)" segfault (but for the wrong reasons, because jumping into nirvana)
or succeeds even.
In normal use this is harmless, as a size with signbit set indicates
more than half the address space which on x86_64 is impossible to
allocate, but as the size is used to index some jump tables this
potentially could have other unwanted side effects.

mktemp always returns TEMPLATE, the caller should check TEMPLATE[0]
instead of TEMPLATE, so do not warn about the unused result.
Fix also the comment for mktemp
[BZ#13926]
Currently __bswap_64 is not defined at all for non-GCC compilers.
Define it but guard it with __GLIBC_HAVE_LONG_LONG.
endian.h uses __bswap_64, make the functions only available
if __GLIBC_HAVE_LONG_LONG is defined.

* stdio-common/printf-parse.h (read_int): Change return type to
'int', return -1 on INT_MAX overflow.
* stdio-common/vfprintf.c (vfprintf): Validate width and precision
against overflow of INT_MAX. Set errno to EOVERFLOW when 'done'
overflows INT_MAX. Check for overflow of in-format-string precision
values properly. Use EOVERFLOW rather than ERANGE throughout. Use
SIZE_MAX not INT_MAX for integer overflow test.
* stdio-common/printf-parsemb.c: If read_int signals an overflow,
skip the construct in the format string but do not record anything.
* stdio-common/bug22.c: Adjust to test both width/prevision
INT_MAX overflow as well as total length INT_MAX overflow. Check
explicitly for proper errno values.
I've improved the following implementation of memcpy:
"sysdeps/i386/i686/multiarch/memcpy-ssse3.S".
The patch includes some minor style fixes, but the important part is
just using prefetch loops for the case:
DATA_CACHE_SIZE_HALF <= len < SHARED_CACHE_SIZE_HALF and
src and dst pointers have unequal 16 byte alignments.
This gives from 6% - 50% performance boost on the atom machine, about
24,73% in geometric mean.
[BZ #13928] A DNS request consists of multiple resources combined into
a single hostent, including multiple CNAME records that may have been
assigned different TTL values. In such a case, nscd should take the
least TTL among all of the resources as the timeout for the hostent
before it is reloaded in its cache so that the hostent remains stale
in the database for the least amount of time.
It isn't necessary to buffer the last character of strings. This can cause a
bug with strings that have 1 character between 0x0041 and 0x01b0.
[BZ #13691]
* iconvdata/tcvn5712-1.c (FROM_LOOP): Fix a bug when converting strings
with only 1 character between 0x0041 and 0x01b0.
* wcsmbs/Makefile (tests): Add tst-mbsnrtowcs.
* wcsmbs/tst-mbsnrtowcs.c: New file.
