2014-09-16Remove bitrotten --enable-oldest-abi (bug 6652).Joseph Myers1-1/+0
This patch removes the --enable-oldest-abi configure option, which has long been bitrotten (as reported in bug 6652). The principle of removing this option was agreed in the thread starting at <https://sourceware.org/ml/libc-alpha/2013-07/msg00174.html>. Tested for x86_64 and x86 that the installed shared libraries other than libc.so are unchanged by this patch and that libc.so disassembly and symbol versions are unchanged (debug info changes because of changed line numbers in csu/version.c). [BZ #6652] * Makeconfig (soversions-default-setname): Remove variable. ($(common-objpfx)soversions.i): Don't pass default_setname to soversions.awk. * Makerules ($(common-objpfx)abi-versions.h): Don't pass oldest_abi to abi-versions.awk. * config.h.in (GLIBC_OLDEST_ABI): Remove macro undefine. * config.make.in (oldest-abi): Remove variable. * configure.ac (--enable-oldest-abi): Remove configure option. * configure: Regenerated. * csu/version.c (banner) [GLIBC_OLDEST_ABI]: Remove conditional text. * scripts/abi-versions.awk: Do not handle oldest_abi variable. * scripts/soversions.awk: Do not handle default_setname variable. * sysdeps/mach/hurd/configure.ac: Do not handle oldest_abi variable. * sysdeps/mach/hurd/configure: Regenerated. * sysdeps/unix/sysv/linux/configure.ac: Do not handle oldest_abi variable. * sysdeps/unix/sysv/linux/configure: Regenerated.
2014-05-09S/390: Port of lock elision to System/zDominik Vogt1-0/+1
Added support for TX lock elision of pthread mutexes on s390 and s390x. This may improve lock scaling of existing programs on TX capable systems. The lock elision code is only built with --enable-lock-elision=yes and then requires a GCC version supporting the TX builtins. With lock elision default mutexes are elided via __builtin_tbegin, if the cpu supports transactions. By default lock elision is not enabled and the elision code is not built.
2014-04-06PowerPC: define _CALL_ELF if compiler does notAdhemerval Zanella1-0/+1
This patch makes the configure adds -D_CALL_ELF=1 when compiler does not define _CALL_ELF (versions before powerpc64le support). It cleans up compiler warnings on old compiler where _CALL_ELF is not defined on powerpc64(be) builds. It does by add a new config.make variable for configure-deduced CPPFLAGS and accumulate into that (confix-extra-cppflags). It also generalizes libc_extra_cflags so it accumulates in sysdeps configure fragmenets.
2014-03-13stop supporting bash-1.xMike Frysinger1-2/+0
We've stopped supporting toolchain packages older than 2009, so punting bash-1.x is reasonable when bash-2 was released almost 20 years ago.
2014-03-13delete ksh checksMike Frysinger1-2/+0
Nothing in the tree uses ksh anymore, so punt these checks.

2013-07-21CVE-2013-2207, BZ #15755: Disable pt_chown.Carlos O'Donell1-0/+1
The helper binary pt_chown tricked into granting access to another user's pseudo-terminal. Pre-conditions for the attack: * Attacker with local user account * Kernel with FUSE support * "user_allow_other" in /etc/fuse.conf * Victim with allocated slave in /dev/pts Using the setuid installed pt_chown and a weak check on whether a file descriptor is a tty, an attacker could fake a pty check using FUSE and trick pt_chown to grant ownership of a pty descriptor that the current user does not own. It cannot access /dev/pts/ptmx however. In most modern distributions pt_chown is not needed because devpts is enabled by default. The fix for this CVE is to disable building and using pt_chown by default. We still provide a configure option to enable hte use of pt_chown but distributions do so at their own risk.

2012-05-10Make sunrpc code usable againAndreas Jaeger1-0/+1
New configure option --enable-obsolete-rpc makes the deprecated RPC headers and functions available at compile time as they were before version 2.14. This option will be removed at some time in the future after the TI-RPC library becomes fully sufficient for the needs of existing applications.
