* linux: sysconf: Use a more explicit maximum_ARG_MAXAdhemerval Zanella2021-04-131-1/+1

* linux: sysconf: limit _SC_MAX_ARG to 6 MiB (BZ #25305)Michal Nazarewicz2021-04-131-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Linux 4.13, kernel limits the maximum command line arguments length to 6 MiB [1]. Normally the limit is still quarter of the maximum stack size but if that limit exceeds 6 MiB it's clamped down. glibc's __sysconf implementation for Linux platform is not aware of this limitation and for stack sizes of over 24 MiB it returns higher ARG_MAX than Linux will actually accept. This can be verified by executing the following application on Linux 4.13 or newer: #include <stdio.h> #include <string.h> #include <sys/resource.h> #include <sys/time.h> #include <unistd.h> int main(void) { const struct rlimit rlim = { 40 * 1024 * 1024, 40 * 1024 * 1024 }; if (setrlimit(RLIMIT_STACK, &rlim) < 0) { perror("setrlimit: RLIMIT_STACK"); return 1; } printf("ARG_MAX : %8ld\n", sysconf(_SC_ARG_MAX)); printf("63 * 100 KiB: %8ld\n", 63L * 100 * 1024); printf("6 MiB : %8ld\n", 6L * 1024 * 1024); char str[100 * 1024], *argv[64], *envp[1]; memset(&str, 'A', sizeof str); str[sizeof str - 1] = '\0'; for (size_t i = 0; i < sizeof argv / sizeof *argv - 1; ++i) { argv[i] = str; } argv[sizeof argv / sizeof *argv - 1] = envp[0] = 0; execve("/bin/true", argv, envp); perror("execve"); return 1; } On affected systems the program will report ARG_MAX as 10 MiB but despite that executing /bin/true with a bit over 6 MiB of command line arguments will fail with E2BIG error. Expected result is that ARG_MAX is reported as 6 MiB. Update the __sysconf function to clamp ARG_MAX value to 6 MiB if it would otherwise exceed it. This resolves bug #25305 which was market WONTFIX as suggested solution was to cap ARG_MAX at 128 KiB. As an aside and point of comparison, bionic (a libc implementation for Android systems) decided to resolve this issue by always returning 128 KiB ignoring any potential xargs regressions [2]. On older kernels this results in returning overly conservative value but that's a safer option than being aggressive and returning invalid value on recent systems. It's also worth noting that at this point all supported Linux releases have the 6 MiB barrier so only someone running an unsupported kernel version would get incorrectly truncated result.

* sysconf: Add _SC_MINSIGSTKSZ/_SC_SIGSTKSZ [BZ #20305]H.J. Lu2021-02-011-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add _SC_MINSIGSTKSZ for the minimum signal stack size derived from AT_MINSIGSTKSZ, which is the minimum number of bytes of free stack space required in order to gurantee successful, non-nested handling of a single signal whose handler is an empty function, and _SC_SIGSTKSZ which is the suggested minimum number of bytes of stack space required for a signal stack. If AT_MINSIGSTKSZ isn't available, sysconf (_SC_MINSIGSTKSZ) returns MINSIGSTKSZ. On Linux/x86 with XSAVE, the signal frame used by kernel is composed of the following areas and laid out as: ------------------------------ | alignment padding | ------------------------------ | xsave buffer | ------------------------------ | fsave header (32-bit only) | ------------------------------ | siginfo + ucontext | ------------------------------ Compute AT_MINSIGSTKSZ value as size of xsave buffer + size of fsave header (32-bit only) + size of siginfo and ucontext + alignment padding. If _SC_SIGSTKSZ_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are redefined as /* Default stack size for a signal handler: sysconf (SC_SIGSTKSZ). */ # undef SIGSTKSZ # define SIGSTKSZ sysconf (_SC_SIGSTKSZ) /* Minimum stack size for a signal handler: SIGSTKSZ. */ # undef MINSIGSTKSZ # define MINSIGSTKSZ SIGSTKSZ Compilation will fail if the source assumes constant MINSIGSTKSZ or SIGSTKSZ. The reason for not simply increasing the kernel's MINSIGSTKSZ #define (apart from the fact that it is rarely used, due to glibc's shadowing definitions) was that userspace binaries will have baked in the old value of the constant and may be making assumptions about it. For example, the type (char [MINSIGSTKSZ]) changes if this #define changes. This could be a problem if an newly built library tries to memcpy() or dump such an object defined by and old binary. Bounds-checking and the stack sizes passed to things like sigaltstack() and makecontext() could similarly go wrong.
* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-1/+1
| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

* linux: Assume clock_getres CLOCK_{PROCESS,THREAD}_CPUTIME_IDAdhemerval Zanella2019-03-221-49/+15
| | | | | | | | | | | | | | | | | | | | | | | | | The Linux 3.2 clock_getres kernel code (kernel/posix-cpu-timers.c) issued for clock_getres CLOCK_PROCESS_CPUTIME_ID (process_cpu_clock_getres) and CLOCK_THREAD_CPUTIME_ID (thread_cpu_clock_getres) call posix_cpu_clock_getres. And it fails on check_clock only if an invalid clock is used (not the case) or if we pass an invalid the pid/tid in 29 msb of clock_id (not the case either). This patch assumes that clock_getres syscall always support CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID, so there is no need to fallback to hp-timing support for _SC_MONOTONIC_CLOCK neither to issue the syscall to certify the clock_id is supported bt the kernel. This allows simplify the sysconf support to always use the syscall. it also removes ia64 itc drift check and assume kernel handles it correctly.

Original is in rpc_common.c. * sysdeps/unix/sysv/linux/alpha/brk.S: When PIC, define __curbrk as a .bss object not a COMMON symbol. * sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S: Must load $gp before referencing __sigsetjmp symbol. Retain LITUSE for same. Optimizations: * sysdeps/alpha/strlen.S: Rearrange first-word setup and thense the main loop for better dual-issue on EV5. Rearrange binary search to pipeline better and trim one instruction. Cosmetic Changes: * time/localtime.c (localtime_r): Move lock declaration back next to the comment where it was before the 960724 change. * INSTALL, manual/maint.texi: alpha-gnu-linux -> alpha-ANYTHING-linux.

(openlog): If connect() with SOCK_DGRAM fails with EPROTOTYPE, try again with SOCK_STREAM (the Linux syslogd uses a socket of the latter type). (vsyslog): When LogType==SOCK_STREAM, also send ASCII NUL terminator as a record-delimiter. If __send(LogFile) fails, call closelog() so logfile gets re-opened next time. Wed Aug 7 15:15:14 1996 Ulrich Drepper <drepper@cygnus.com> * elf/dl-open (_dl_open): Add cast to avoid warning. * manual/memory.texi: Improve some examples to give readers better advice: Use `stpcpy' instead of `strcat' if possible. * manual/string.texi: Document `strtok_r' and `strtok'. * sunrpc/Makefile: Move `+gccwarn' definition before inclusion of Makeconfig. [$(cross-compiling)=no]: Change test before making librpcsvc to this from $(cross-compile). Reported by Andreas Schwab. Tue Aug 6 14:27:11 1996 Ulrich Drepper <drepper@cygnus.com> * elf/Makefile (routines): Move dl-sysdep to here... (rtld-routines): ...from here. This should make static linking work again. * locale/setlocale.c: Add local variable `lock' and add code to `setlocale' to avoid simultaneous changing of global data. * catgets/catgets.c (catopen): Use `__strdup' instead of `strdup'. * catgets/open_catalog (__open_catalog): Use `__stpcpy', `__open', `__fstat', `__read', `__mmap', `__munmap' and `__close' instead of unprotected names.
