* Assume prlimit64 is available.Joseph Myers2017-05-095-85/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch makes sysdeps/unix/sysv/linux code assume the prlimit64 syscall is always available, given the minimum of a 3.2 kernel. __ASSUME_PRLIMIT64, which in fact was no longer used, is removed. Code conditional on __NR_prlimit64 being defined is made unconditional. Fallback code for the case where prlimit64 produces an ENOSYS error is removed, substantially simplifying some functions. Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_PRLIMIT64): Remove macro. * sysdeps/unix/sysv/linux/getrlimit64.c (__getrlimit64): Assume prlimit64 is always available and does not give an ENOSYS error. * sysdeps/unix/sysv/linux/prlimit.c [__NR_prlimit64]: Make code unconditional. [!__NR_prlimit64]: Remove conditional code. * sysdeps/unix/sysv/linux/setrlimit.c (__setrlimit): Assume prlimit64 is always available and does not give an ENOSYS error. * sysdeps/unix/sysv/linux/setrlimit64.c (__setrlimit64): Likewise.
* Remove __ASSUME_PROC_PID_TASK_COMM.Joseph Myers2017-05-082-19/+0
| | | | | | | | | | | | | | This patch removes the __ASSUME_PROC_PID_TASK_COMM macro, and associated conditional code (in a testcase), now that 3.2 is the global minimum Linux kernel version supported. Tested for x86_64. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_PROC_PID_TASK_COMM): Remove macro. * sysdeps/unix/sysv/linux/tst-setgetname.c: Do not include <kernel-features.h>. (do_test) [!__ASSUME_PROC_PID_TASK_COMM]: Remove conditional code.
* Remove __ASSUME_GETCPU_SYSCALL.Joseph Myers2017-05-081-5/+0
| | | | | | | | | | | | | | | | | | | This patch removes the definition of __ASSUME_GETCPU_SYSCALL. In fact this macro is unused, probably since: commit dd26c44403582fdf10d663170f947dfe4b3207a0 Author: Adhemerval Zanella <adhemerval.zanella@linaro.com> Date: Wed Apr 22 14:21:39 2015 -0300 Consolidate sched_getcpu so it could have been removed even without the move to 3.2 as minimum kernel version on x86_64. Tested for x86_64. * sysdeps/unix/sysv/linux/x86_64/kernel-features.h (__ASSUME_GETCPU_SYSCALL): Remove macro.

* Require Linux kernel 3.2 or later on x86 / x86_64.Joseph Myers2017-05-084-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As per the recent discussion, this patch implements a requirement for Linux 3.2 or later for x86 and x86_64. This is only the initial change to increase the configured minimum; it's expected that followup patches would deal with associated removal of conditionals that are no longer needed. If we remove the start-up test on the kernel version, of course the NEWS and README text should then be revised (to reflect that this version is just one such that glibc does not intend to include compatibility code for any older kernel version, rather than older kernels necessarily failing to work or glibc necessarily having compatibility code for newer interfaces). The followups would be able to assume presence of getcpu (x86_64), recvmmsg (not always through its own syscall, sometimes only through socketcall), sendmmsg (likewise), /proc/$pid/task/$tid/comm, f_flags from statfs, prlimit64. Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/i386/configure.ac (arch_minimum_kernel): Remove. * sysdeps/unix/sysv/linux/i386/configure: Regenerated. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac (arch_minimum_kernel): Remove. * sysdeps/unix/sysv/linux/x86_64/64/configure: Regenerated. * README: Update statement about Linux kernel requirements.
* Use __glibc_reserved convention in mcontext, sigcontext (bug 21457).Joseph Myers2017-05-043-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the most straightforward part of fixing namespace issues for sys/ucontext.h and related headers: where fields in sys/ucontext.h or bits/sigcontext.h are named "reserved", "padding" or similar, they are renamed to use the __glibc_reserved* naming convention. It does not change fields with a leading underscore, or even those with a prefix such as uc_ or sc_. It only fixes a small part of bug 21457, so no XFAILs are removed. Tested for x86_64 and x86, and with build-many-glibcs.py. [BZ #21457] * sysdeps/unix/sysv/linux/mips/sys/ucontext.h [_MIPS_SIM != _ABIO32] (mcontext_t): Rename field reserved to __glibc_reserved1. * sysdeps/unix/sysv/linux/x86/bits/sigcontext.h (struct _fpx_sw_bytes): Rename field padding to __glibc_reserved1.

* x86: Set dl_platform and dl_hwcap from CPU features [BZ #21391]H.J. Lu2017-05-032-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dl_platform and dl_hwcap are set from AT_PLATFORM and AT_HWCAP very early during startup. They are used by dynamic linker to determine platform and build an array of hardware capability names, which are added to search path when loading shared object. dl_platform and dl_hwcap are unused on x86-64. On i386, i386, i486, i586 and i686 platforms were supported and only SSE2 capability was used. On x86, usage of AT_PLATFORM and AT_HWCAP to determine platform and processor capabilities is obsolete since all information is available in dl_x86_cpu_features. This patch sets dl_platform and dl_hwcap from dl_x86_cpu_features in dynamic linker. On i386, the available plaforms are changed to i586 and i686 since i386 has been deprecated. On x86-64, the available plaforms are haswell, which is for Haswell class processors with BMI1, BMI2, LZCNT, MOVBE, POPCNT, AVX2 and FMA, and xeon_phi, which is for Xeon Phi class processors with AVX512F, AVX512CD, AVX512ER and AVX512PF. A capability, avx512_1, is also added to x86-64 for AVX512 ISAs: AVX512F, AVX512CD, AVX512BW, AVX512DQ and AVX512VL. [BZ #21391] * sysdeps/i386/dl-machine.h (dl_platform_init) [IS_IN (rtld)]: Only call init_cpu_features.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates the select Linux syscall implementation on sysdeps/unix/sysv/linux/select.c. The changes are: 1. Remove select from auto-generation syscalls.list on the architecture that uses __NR_select. 2. Remove generic implementation add a default one that handle all current cases (with the expection of alpha) The new default implementation will either use __NR_select if available of fallback to __NR_pselect6 otherwise. 3.

| | | | | | | | | | | | | | | | This patch consolidates the poll Linux syscall implementation on sysdeps/unix/sysv/linux/poll.c. It basically removes poll from auto-generation list and add a default implementation that either call __NR_poll directly (if the kernel headers defines it) or ppoll adjusting the timeout argument (as the generic implementation). Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/generic/poll.c: Remove file. * sysdeps/unix/sysv/linux/poll.c: New file. * sysdeps/unix/sysv/linux/syscalls.list: Remove poll from auto-generation list.

* posix: Fix internal p{read,write} plt usageAdhemerval Zanella2017-05-024-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds internal alias for __pread, __pread64, and __pwrite following the already in place one for __pwrite64. This is not used in any implementation but on microblaze on preadv/pwritev fallback (since it does not define __ASSUME_PREADV). In fact it was signaled by commit c35db50ff5 which update the expected localptl.data for the architecture based on resulted value. This patch updates the plt for microblaze now that p{read,write}{64} are correctly routed to use internal alias. Checked on x86_64-linux-gnu and a build for all supported architectures (no all variants although). * include/unistd.h (__pread): Add libc_hidden_proto. (__pread64): Likewise.

* Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426).Joseph Myers2017-04-251-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys/socket.h includes sys/uio.h to get the definition of the iovec structure. POSIX allows sys/socket.h to make all sys/uio.h symbols visible. However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this results in conformtest failures (for sys/socket.h and other headers that include it): Namespace violation: "UIO_MAXIOV" Namespace violation: "readv" Namespace violation: "writev" Now, there is some ambiguity in POSIX about what namespace reservations apply in this case - see http://austingroupbugs.net/view.php?id=1127 - but glibc convention would still avoid declaring readv and writev, for example, for feature test macros that don't include them (if only headers from the relevant standard are included), even if such declarations are permitted, so there is a bug here according to glibc conventions. This patch moves the struct iovec definition to a new bits/types/struct_iovec.h header and includes that from sys/socket.h instead of including the whole of sys/uio.h. This fixes the namespace issue; however, three files in glibc that were relying on the implicit inclusion needed to be updated to include sys/uio.h explicitly. So there is a question of whether sys/socket.h should continue to include sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or __USE_XOPEN || __USE_MISC, for greater compatibility with code that (wrongly) expects this optional inclusion to be present there. (I think the three affected files in glibc should still have explicit sys/uio.h inclusions added in any case, however.) Tested for x86_64. [BZ #21426] * misc/bits/types/struct_iovec.h: New file. * misc/Makefile (headers): Add bits/types/struct_iovec.h. * include/bits/types/struct_iovec.h: New file. * bits/uio.h (struct iovec): Replace by inclusion of <bits/types/struct_iovec.h>. * sysdeps/unix/sysv/linux/bits/uio.h (struct iovec): Likewise. * socket/sys/socket.h: Include <bits/types/struct_iovec.h> instead of <sys/uio.h>. * nptl/tst-cancel4.c: Include <sys/uio.h> * posix/test-errno.c: Likewise. * support/resolv_test.c: Likewise. * conform/Makefile (test-xfail-POSIX2008/arpa/inet.h/conform): Remove.

| | | | | | | | | | Simplify the Linux accept4 implementation based on the assumption that it is available in some way. __ASSUME_ACCEPT4_SOCKETCALL was previously unused, so remove it.

* Fix bits/socket.h IOC* namespace issues (bug 21267).Joseph Myers2017-04-181-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysdeps/unix/sysv/linux/bits/socket.h includes asm/socket.h. That includes asm/sockios.h, which on MIPS includes asm/ioctl.h, resulting in namespace violations from IOC* macros. bits/socket.h already has code to handle asm/socket.h unconditionally defining macros that are only wanted for __USE_MISC. This patch extends it to handle the IOC* macros as well (always undefining them if not defined when bits/socket.h was included, as I don't think they are part of the intended API even for __USE_MISC). It's possible there should also be a kernel fix - it's not clear to me that IOC* belong in the uapi headers, and even if they do they might best be split out into another header to avoid getting defined by this particular path. But since glibc needs to deal with existing kernel headers, it also seems appropriate to extend the existing workaround to these macros. Tested (compilation only) with build-many-glibcs.py.

* Consolidate Linux mmap implementation (BZ#21270)Adhemerval Zanella2017-04-1223-565/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates all Linux mmap implementations on default sysdeps/unix/sysv/linux/mmap{64}.c one. To accomodate all required architecture specific requeriments a new internal header is created (mmap_internal.h) where each architecture add its specific code requirements. Currently only x86_64 (to define MMAP_PREPARE to add MAP_32BITS), s390 (which have a different kernel ABI for mmap), m68k (which have variable minimum page sizes), and MIPS n32 (which zero extend the offset to handle negative one correctly) redefine the new header. The patch also fixes BZ#21270 where default mmap64 on architectures which uses mmap2 silent truncates large offsets value (larger than 1 << (page shift + 8 * sizeof (off_t)) or 1<<44 on architectures with 4096 bytes page size). The new consolidate implementation returns EINVAL as allowed by POSIX. It also adds a tests for on current tst-mmap-offset one. I have run a full make check on x86_64, x86_64-32, i686, aarch64, armhf, powerpc, powerpc64le, sparc64, and sparcv9 without any regressions. I also ran some basic tests (tst-mmap-offset) on sh4, m68k, and on qemu simulated MIPS32 and MIPS64. [BZ #21270] * posix/tst-mmap-offset.c (do_prepare): New function.

* Build divdi3 only for architecture that required itAdhemerval Zanella2017-04-064-0/+26

This patch refact the make rules for this object to so only the aforementioned architectures that actually require it builds it. Also, to avoid internal PLT calls to the exported symbol from the module, glibc uses an internal header (symbol-hacks.h) which is unrequired (and in fact breaks the build for architectures that intend to get symbol definitions from libgcc.a). The patch also changes it to create its own header (divdi3-symbol-hacks.h) and adjust the architectures that require it accordingly. I checked the build/check (with run-built-tests=no) on the following architectures (which I think must cover all supported ABI/builds) using GCC 6.3: aarch64-linux-gnu alpha-linux-gnu arm-linux-gnueabihf hppa-linux-gnu ia64-linux-gnu m68k-linux-gnu microblaze-linux-gnu mips64-n32-linux-gnu mips-linux-gnu mips64-linux-gnu nios2-linux-gnu powerpc-linux-gnu powerpc-linux-gnu-power4 powerpc64-linux-gnu powerpc64le-linux-gnu s390x-linux-gnu s390-linux-gnu sh4-linux-gnu sh4-linux-gnu-soft sparc64-linux-gnu sparcv9-linux-gnu tilegx-linux-gnu tilegx-linux-gnu-32 tilepro-linux-gnu x86_64-linux-gnu x86_64-linux-gnu-x32 i686-linux-gnu I only saw one regression on sparcv9-linux-gnu (extra PLT call to .udiv) which I address in next patch in the set.

* posix_spawn: use a larger min stack for -fstack-check [BZ #21253]Mike Frysinger2017-04-031-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | When glibc is built with -fstack-check, trying to use posix_spawn can lead to segfaults due to gcc internally probing stack memory too far. The new spawn API will allocate a minimum of 1 page, but the stack checking logic might probe a couple of pages. When it tries to walk them, everything falls apart. The gcc internal docs [1] state the default interval checking is one page. Which means we need two pages (the current one, and the next probed). No target currently defines it larger. Further, it mentions that the default minimum stack size needed to recover from an overflow is 4/8KiB for sjlj or 8/12KiB for others. But some Linux targets (like mips and ppc) go up to 16KiB (and some non-Linux targets go up to 24KiB). Let's create each child with a minimum of 32KiB slack space to support them all, and give us future breathing room. No test is added as existing ones crash. Even a simple call is enough to trigger the problem: char *argv[] = { "/bin/ls", NULL }; posix_spawn(NULL, "/bin/ls", NULL, NULL, argv, NULL); [1] https://gcc.gnu.org/onlinedocs/gcc-6.3.0/gccint/Stack-Checking.html
* Fix more test-errno issuesAdhemerval Zanella2017-03-301-2/+7
| | | | | | | | | | | | | | | | | | This patch fixes some test-errno-linux unexpected returns for the tested syscalls on some older kernels (I saw it on a Linux 3.8 on armv7l).

* Define more termios.h macros unconditionally for alpha (bug 21277).Joseph Myers2017-03-271-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | termios.h should define IUCLC for UNIX98 and older XSI standards. The sysdeps/unix/sysv/linux/alpha version defines it only if __USE_MISC, so causing some conform/ tests to fail. Other versions define it unconditionally (I* being a reserved namespace for this header); the API should be consistent between architectures in the absence of a clear reason for it to differ (and given that a symbol is part of the API on two architectures, I don't see any reason for the feature test macros required ever to differ between those architectures), so this patch makes the alpha version define it unconditionally as well. Two non-POSIX macros alongside it, IMAXBEL and IUTF8, are also defined unconditionally on other architectures, so this patch makes them consistent by defining them unconditionally on alpha as well. Tested (compilation only) with build-many-glibcs.py. [BZ #21277] * sysdeps/unix/sysv/linux/alpha/bits/termios.h (IUCLC): Define unconditionally. (IMAXBEL): Likewise. (IUTF8): Likewise.

But /dev/pts/2 is NOT the current tty, it is a different file and device. Detect this case and return ENODEV.

It was done instead of defining in default kernel-features.h because current Linux practice for new ports are to implement only __NR_sendto [1] and it will require adding new kernel-features for ports that do not require it (aarch64 for instance). 3. Remove __ASSUME_SENDTO_FOR_SEND_SYSCALL and decide to use __NR_sendto for send generation based on __ASSUME_SENDTO_SYSCALL.
