Ulrich Drepper 356f8bc660 2.14 release 2011-05-31 00:12:33 -04:00
Ulrich Drepper 34a9094f49 Don't unconditionally use alloca in gaih_inet 2011-05-20 23:46:03 -04:00
Ulrich Drepper 94b7cc3711 Fix a few problems in fopen and freopen
fopen should set the FD_CLOEXEC flag if requested evenif the kernel does
not support an aotmic operation.

freopen should reuse the file descriptor for the stream.  This is
especially important for calls to change the standard streams (stin,
stdout, stderr).

Ulrich Drepper 7fb90fb89b Fix Linux getcwd for long paths
The getcwd syscall (so far?) can only handle path up to one page
in size.  There is no limit about directory hierarchy depth, though,
and the POSIX getcwd is supposed to handle this.  In that case fall
back to the generic getcwd.

Additionally, optimize the generic getcwd to use openat when possible
to change the asymptotic performance from O(N^2) to O(n).

Ulrich Drepper b9ea2dd05e Fix handling of __need_mbstate_t and __need_wint_t.
Like the real header, the libc-internal wrapper for wchar.h needs to
undefine the macros so that if the header was already included before
the macros don't stay defined and cause problems later.
2010-03-27 06:06:35 -07:00
Ulrich Drepper c8727fa6e5 Fix Linux getlogin{_r,} implementation
The old implementation uses fd 0 to determine the login TTY.  This
was needed because using /dev/tty it is not possible to deduce the
login TTY.  For some time now there is the pseudo-file
/proc/self/loginuid which directly helps us to find the user.  Prefer
using this file.  It also works if stdin is closed, redirected, or
re-opened.

Ulrich Drepper f095bb7204 Add support for XPG7 testing.
The header conformance testing code needed extending for XPG7.  This
exposed a few bugs in the headers.  There are more changes to come.

Ulrich Drepper 63de5ef70a Fix isomac test after recent header change. 2009-12-23 19:31:50 -08:00
Ulrich Drepper 2af6396817 Avoid ELF lookup race.
On some architectures the update of the l_used field in the lookup
functions races with setting the other bits in the bitfield.  Simply
avoid this and optimize use of l_used in general.

Ulrich Drepper aa9890239a Optimize grantpt.
grantpt was performing two consecutive calls to stat with the same
file name.  Avoid this by creating a special version of the ptsname
function which allows to pass the stat result back to the caller.

Ulrich Drepper 9a1d2d4555 Prepare use if IFUNC functions outside libc.so.
We use a callback function into libc.so to get access to the data
structure with the information and have special versions of the test
macros which automatically use this function.

Duncan Simpson 30a2dfd518 Make include/unistd.h suitable for C++ test cases. 2009-07-23 12:39:17 -07:00
Jakub Jelinek bea0ac1d87 Use rel semantics of cas instead of acq semantics with full barrier before it in _int_free
The following patch fixes catomic_compare_and_exchange_*_rel definitions
(which were never used and weren't correct) and uses
catomic_compare_and_exchange_val_rel in _int_free.  Comparing to the
pre-2009-07-02 --enable-experimental-malloc state the generated code should
be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use
lwsync instead of isync barrier.

Ulrich Drepper 48dcd0ba84 Preserve message printed before abort.
The terminal output etc is not visible in a core file.  The new
libc-internal variable __abort_msg will point to a string with the
message which has been printed before the abort in case abort is
called from inside libc.  BZ #10217

Ulrich Drepper b50f8e42ba Check for valid stack frame in longjmp.
If longjmp restores the stack frame to an address which is beyond
the stack frame at the time of the longjmp call it would install
an uninitialized stack frame.  If compiled with _FORTIFY_SOURCE
defined, longjmp will now bail out in this situation.
