2013-10-04PowerPC SIGSTKSZAlan Modra1-0/+54
http://sourceware.org/ml/libc-alpha/2013-08/msg00093.html This copies the sparc version of sigstack.h, which gives powerpc #define MINSIGSTKSZ 4096 #define SIGSTKSZ 16384 Before the VSX changes, struct rt_sigframe size was 1920 plus 128 for __SIGNAL_FRAMESIZE giving ppc64 exactly the default MINSIGSTKSZ of 2048. After VSX, ucontext increased by 256 bytes. Oops, we're over MINSIGSTKSZ, so powerpc has been using the wrong value for quite a while. Add another ucontext for TM and rt_sigframe is now at 3872, giving actual MINSIGSTKSZ of 4000. The glibc testcase that I was looking at was tst-cancel21, which allocates 2*SIGSTKSZ (not because the test is trying to be conservative, but because the test actually has nested signal stack frames). We blew the allocation by 48 bytes when using current mainline gcc to compile glibc (le ppc64). The required stack depth in _dl_lookup_symbol_x from the top of the next signal frame was 10944 bytes. I guess you'd want to add 288 to that, implying an actual SIGSTKSZ of 11232. * sysdeps/unix/sysv/linux/powerpc/bits/sigstack.h: New file.

2013-09-06Coordinate IPv6 definitions for Linux and glibcCarlos O'Donell1-0/+12
This change synchronizes the glibc headers with the Linux kernel headers and arranges to coordinate the definition of structures already defined the Linux kernel UAPI headers. It is now safe to include glibc's netinet/in.h or Linux's linux/in6.h in any order in a userspace application and you will get the same ABI. The ABI is guaranteed by UAPI and glibc.

2013-07-23PowerPC: use _dl_static_init to set GLRO(gl_pagesize)Adhemerval Zanella4-0/+129
This patch fixes dlfcn/tststatic5 for PowerPC where pagesize variable was not properly initialized in certain cases. This patch is based on other architecture code.
2013-07-21CVE-2013-2207, BZ #15755: Disable pt_chown.Carlos O'Donell1-2/+3
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.
2013-07-16BZ #15711: Avoid circular dependency for syscall.hCarlos O'Donell1-2/+9
The generated header is compiled with `-ffreestanding' to avoid any circular dependencies against the installed implementation headers. Such a dependency would require the implementation header to be installed before the generated header could be built (See bug 15711). In current practice the generated header dependencies do not include any of the implementation headers removed by the use of `-ffreestanding'. --- 2013-07-15 Carlos O'Donell <carlos@redhat.com> [BZ #15711] * sysdeps/unix/sysv/linux/Makefile ($(objpfx)bits/syscall%h): Avoid system header dependency with -ffreestanding. ($(objpfx)bits/syscall%d): Likewise.

2013-06-15New API to set default thread attributesSiddhesh Poyarekar10-0/+40
This patch introduces two new convenience functions to set the default thread attributes used for creating threads. This allows a programmer to set the default thread attributes just once in a process and then run pthread_create without additional attributes.
2013-06-13Improve precision of clock() function on LinuxSiddhesh Poyarekar1-20/+16

2013-06-11Fix symbol definitions for __clock_* functionsSiddhesh Poyarekar2-5/+5
__clock_gettime and other __clock_* functions could result in an extra PLT reference within libc.so if it actually gets used. None of the code currently uses them, which is why this probably went unnoticed.

2013-05-03PowerPC: Add time vDSO supportAdhemerval Zanella4-3/+70
PowerPC kernel now provides a vDSO implementation for time syscall (commit fcb41a2030abe0eb716ef0798035ef9562097f42). This patch changes time syscall wrapper to use the vDSO when available. It also changes the default non vDSO time on PowerPC to use sysdeps/posix/time.c (since gettimeofday is a vDSO call).

2013-04-23S/390: Change struct statfs[64] member types to unsigned valuesHeiko Carstens1-12/+12
Kay Sievers reported that coreutils' stat tool has a problem with s390's statfs[64] definition: > The definition of struct statfs::f_type needs a fix. s390 is the only > architecture in the kernel that uses an int and expects magic > constants lager than INT_MAX to fit into. > > A fix is needed to make Fedora boot on s390, it currently fails to do > so. Userspace does not want to add code to paper-over this issue. [...] > Even coreutils cannot handle it: > #define RAMFS_MAGIC 0x858458f6 > # stat -f -c%t / > ffffffff858458f6 > > #define BTRFS_SUPER_MAGIC 0x9123683E > # stat -f -c%t /mnt > ffffffff9123683e The bug is caused by an implicit sign extension within the stat tool: out_uint_x (pformat, prefix_len, statfsbuf->f_type); where the format finally will be "%lx". A similar problem can be found in the 'tail' tool. s390 is the only architecture which has an int type f_type member in struct statfs[64]. Other architectures have either unsigned ints or long values, so that the problem doesn't occur there. Therefore change the type of the f_type member to unsigned int, so that we get zero extension instead sign extension when assignment to a long value happens.
