* sln: use stat64Hongjiu Zhang2016-03-072-2/+7
| | | | | | | | | | | | | When using sln on some filesystems which return 64-bit inodes, the stat call might fail during install like so: .../elf/sln .../elf/symlink.list /lib32/libc.so.6: invalid destination: Value too large for defined data type /lib32/ld-linux.so.2: invalid destination: Value too large for defined data type Makefile:104: recipe for target 'install-symbolic-link' failed Switch to using stat64 all the time to avoid this.

* test-skeleton.c: Do not set RLIMIT_DATA [BZ #19648]Florian Weimer2016-03-072-17/+5
| | | | | | | | | With older kernels, it is mostly ineffective because it causes malloc to switch from sbrk to mmap (potentially invalidating malloc testing compared to what real appliations do). With newer kernels which have switched to enforcing RLIMIT_DATA for mmap as well, some test cases will fail in an unintended fashion because the limit which was set previously does not include room for all mmap mappings.
* posix: New Linux posix_spawn{p} implementationAdhemerval Zanella2016-03-0727-2/+547
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a new posix_spawn{p} implementation for Linux. The main difference is it uses the clone syscall directly with CLONE_VM and CLONE_VFORK flags and a direct allocated stack. The new stack and start function solves most the vfork limitation (possible parent clobber due stack spilling). The remaning issue are related to signal handling: 1. That no signal handlers must run in child context, to avoid corrupt parent's state. 2. Child must synchronize with parent to enforce stack deallocation and to possible return execv issues. The first one is solved by blocking all signals in child, even NPTL-internal ones (SIGCANCEL and SIGSETXID). The second issue is done by a stack allocation in parent and a synchronization with using a pipe or waitpid (in case or error). The pipe has the advantage of allowing the child signal an exec error (checked with new tst-spawn2 test). There is an inherent race condition in pipe2 usage for architectures that do not support the syscall directly. In such cases the a pipe plus fctnl is used instead and it may lead to file descriptor leak in parent (as decribed by fcntl documentation). The child process stack is allocate with a mmap with MAP_STACK flag using default architecture stack size. Although it is slower than use a stack buffer from parent, it allows some slack for the compatibility code to run scripts with no shebang (which may use a buffer with size depending of argument list count). Performance should be similar to the vfork default posix implementation and way faster than fork path (vfork on mostly linux ports are basically clone with CLONE_VM plus CLONE_VFORK). The only difference is the syscalls required for the stack allocation/deallocation. It fixes BZ#10354, BZ#14750, and BZ#18433. Tested on i386, x86_64, powerpc64le, and aarch64.

* posix: execvpe cleanupAdhemerval Zanella2016-03-0713-151/+529
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes all the dynamic allocation on execvpe code and instead use direct stack allocation. This is QoI approach to make it possible use in scenarios where memory is shared with parent (vfork or clone with CLONE_VM). For default process spawn (script file without a shebang), stack allocation is bounded by NAME_MAX plus PATH_MAX plus 1. Large file arguments returns an error (ENAMETOOLONG). This differs than current GLIBC pratice in general, but it used to limit stack allocation for large inputs. Also, path in PATH environment variable larger than PATH_MAX are ignored. The shell direct execution exeception, where execve returns ENOEXEC, might requires a large stack allocation due large input argument list.

* posix: Remove dynamic memory allocation from execl{e,p}Adhemerval Zanella2016-03-074-125/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | GLIBC execl{e,p} implementation might use malloc if the total number of arguments exceed initial assumption size (1024). This might lead to issues in two situations: 1. execl/execle is stated to be async-signal-safe by POSIX [1]. However if execl is used in a signal handler with a large argument set (that may call malloc internally) and if the resulting call fails it might lead malloc in the program in a bad state. 2. If the functions are used in a vfork/clone(VFORK) situation it also might issue malloc internal bad state. This patch fixes it by using stack allocation instead. It also fixes BZ#19534. Tested on x86_64.

* Enable --localedir to set message catalog directory (Bug 14259)Carlos O'Donell2016-02-248-12/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 1999 the project split "localedir" into "localedir" (path to compiled locale archives) and "msgcatdir" (path to message catalogs). This predates the 2002 change in the GNU Coding Standard to document the use of "localedir" for the path to the message catalogs. It appears that newlib, gcc, and several other projects also used "msgcatdir" at one point or another in the past, and so it is in line with historical precedent that glibc would also use "msgcatdir." However, given that the GNU Coding Standard uses "localedir", we will switch to that for consistency as a GNU project. Previous uses of --localdir didn't work anyway (see bug 14259). I am committing this patch in the understanding that nobody would object to fixing #14259 as part of aligning our variable usage to the GNU Coding Standard. Given that previous "localedir" uses were converted to "complocaledir" by [1], we can now convert "msgcatdir" to "localedir" and complete the transition. With an addition to config.make.in we also fix bug 14259 and allow users to specify the locale dependent data directory with "--localedir" at configure time. There is still no way to control at configure time the location of the *compiled* locale directory. Tested on x86_64 with no regressions. Tested using "--localedir" to specify alternate locale dependent data directory and verified with "make install DESTDIR=/tmp/glibc". [1] 90fe682d3067163aa773feecf497ef599429457a

* Require Linux 3.2 except on x86 / x86_64, 3.2 headers everywhere.Joseph Myers2016-02-2411-15/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In <https://sourceware.org/ml/libc-alpha/2016-01/msg00885.html> I proposed a minimum Linux kernel version of 3.2 for glibc 2.24, since Linux 2.6.32 has reached EOL. In the discussion in February, some concerns were expressed about compatibility with OpenVZ containers. It's not clear that these are real issues, given OpenVZ backporting kernel features and faking the kernel version for guest software, as discussed in <https://sourceware.org/ml/libc-alpha/2016-02/msg00278.html>. It's also not clear that supporting running GNU/Linux distributions from late 2016 (at the earliest) on a kernel series from 2009 is a sensible expectation. However, as an interim step, this patch increases the requirement everywhere except x86 / x86_64 (since the controversy was only about those architectures); the special caveats and settings can easily be removed later when we're ready to increase the requirements on x86 / x86_64 (and if someone would like to raise the issue on LWN as suggested in the previous discussion, that would be welcome). 3.2 kernel headers are required everywhere by this patch. (x32 already requires 3.4 or later, so is unaffected by this patch.) As usual for such a change, this patch only changes the configure scripts and associated documentation. The intent is to follow up with removal of dead __LINUX_KERNEL_VERSION conditionals. Each __ASSUME_* or other macro that becomes dead can then be removed independently.

Since SSE optimized memory/string functions with aligned SSE register load and store are used in the dynamic linker, we must set DL_RUNTIME_UNALIGNED_VEC_SIZE to 8 so that _dl_runtime_resolve_sse will align the stack before calling _dl_fixup: Dump of assembler code for function _dl_runtime_resolve_sse: 0x00007ffff7deea90 <+0>: push %rbx 0x00007ffff7deea91 <+1>: mov %rsp,%rbx 0x00007ffff7deea94 <+4>: and $0xfffffffffffffff0,%rsp ^^^^^^^^^^^ Align stack to 16 bytes 0x00007ffff7deea98 <+8>: sub $0x100,%rsp 0x00007ffff7deea9f <+15>: mov %rax,0xc0(%rsp) 0x00007ffff7deeaa7 <+23>: mov %rcx,0xc8(%rsp) 0x00007ffff7deeaaf <+31>: mov %rdx,0xd0(%rsp) 0x00007ffff7deeab7 <+39>: mov %rsi,0xd8(%rsp) 0x00007ffff7deeabf <+47>: mov %rdi,0xe0(%rsp) 0x00007ffff7deeac7 <+55>: mov %r8,0xe8(%rsp) 0x00007ffff7deeacf <+63>: mov %r9,0xf0(%rsp) 0x00007ffff7deead7 <+71>: movaps %xmm0,(%rsp) 0x00007ffff7deeadb <+75>: movaps %xmm1,0x10(%rsp) 0x00007ffff7deeae0 <+80>: movaps %xmm2,0x20(%rsp) 0x00007ffff7deeae5 <+85>: movaps %xmm3,0x30(%rsp) 0x00007ffff7deeaea <+90>: movaps %xmm4,0x40(%rsp) 0x00007ffff7deeaef <+95>: movaps %xmm5,0x50(%rsp) 0x00007ffff7deeaf4 <+100>: movaps %xmm6,0x60(%rsp) 0x00007ffff7deeaf9 <+105>: movaps %xmm7,0x70(%rsp) [BZ #19679] * sysdeps/x86_64/dl-trampoline.S (DL_RUNIME_UNALIGNED_VEC_SIZE): Renamed to ...

* elf.h: Add NT_ARM_SYSTEM_CALL constant.Mark Wielaard2016-02-192-0/+5

* elf/elf.h: Add new 386 and X86_64 relocations from binutils.Mark Wielaard2016-02-192-3/+20
| | | | | | | | | | | | | | | | | | | | | | | The following new 386 and X86_64 were added to binutils. They are non-dynamic relocations, so don't need direct handling in glibc. But other programs, like elfutils, use the glibc elf.h definitions for the names and numbers when inspecting ET_REL files. R_386_GOT32X was proposed in https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX were proposed in https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0 There also used to be R_X86_64_PC32_BND and R_X86_64_PLT32_BND but those already got deprecated in https://groups.google.com/d/msg/x86-64-abi/-hdQyMixt8Y/XFDOvioG85cJ * elf/elf.h (R_386_GOT32X): New.

* test-skeleton: increase default TIMEOUT to 20 secondsMike Frysinger2016-02-192-2/+7
| | | | | | | | | | | | | | | | | | | The vast majority of timeouts I've seen w/glibc tests are due to: - slow system (e.g. <1 GHz cpu) - loaded system (e.g. lots of parallelism) Even then, I've seen timeouts on system I don't generally consider slow, or even loaded, and considering TIMEOUT is set to <=10 in ~60 tests (and <=20 in ~75 tests), it seems I'm not alone. I've just gotten in the habit of doing `export TIMEOUTFACTOR=10` on all my setups. In the edge case where there is a bug in the test and the timeout is hit, I think we all agree that's either a problem with the test or a real bug in the library somewhere. In either case, the incident rate should be low, so catering to that seems like the wrong trade-off. Other developers too usually set large timeout factors. Increase the default to 20 seconds to match reality.
* locales: pap_AN: delete old/deprecated locale [BZ #16003]Mike Frysinger2016-02-194-158/+9
| | | | | | | | | From the bug: Netherlands Antilles was dissolved, and "AN" is not a part of ISO 3166 anymore. According to setlocale(3), "territory is an ISO 3166 country code". We now have pap_AW and pap_CW. Reported-by: Chris Leonard <cjlhomeaddress@gmail.com>

Note: the Dominican Republic (DO) and Puerto Rico (PR) updates are correct: they both use +1. Historically, DO had one area code of 809 and PR of 787 which is why they were listed as such, but they have both expanded into 829 and 989 respectively, so using the four digit value is def incorrect now.

* Fix ldbl-128ibm nextafterl, nexttowardl sign of zero result (bug 19678).Joseph Myers2016-02-192-0/+10
| | | | | | | | | | | | | | The ldbl-128ibm implementation of nextafterl / nexttowardl returns -0 in FE_DOWNWARD mode when taking the next value below the least positive subnormal, when it should return +0. This patch fixes it to check explicitly for this case. Tested for powerpc. [BZ #19678] * sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c (__nextafterl): Ensure +0.0 is returned when taking the next value below the least positive value.
