* nptl: Cleanup cancellation macrosAdhemerval Zanella2019-01-0315-164/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch wraps all uses of *_{enable,disable}_asynccancel and and *_CANCEL_{ASYNC,RESET} in either already provided macros (lll_futex_timed_wait_cancel) or creates new ones if the functionality is not provided (SYSCALL_CANCEL_NCS, lll_futex_wait_cancel, and lll_futex_timed_wait_cancel). Also for some generic implementations, the direct call of the macros are removed since the underlying symbols are suppose to provide cancellation support. This is a priliminary patch intended to simplify the work required for BZ#12683 fix. It is a refactor change, no semantic changes are expected. Checked on x86_64-linux-gnu and i686-linux-gnu. * nptl/pthread_join_common.c (__pthread_timedjoin_ex): Use lll_wait_tid with timeout. * nptl/sem_wait.c (__old_sem_wait): Use lll_futex_wait_cancel. * sysdeps/nptl/aio_misc.h (AIO_MISC_WAIT): Use futex_reltimed_wait_cancelable for cancelabla mode. * sysdeps/nptl/gai_misc.h (GAI_MISC_WAIT): Likewise. * sysdeps/posix/open64.c (__libc_open64): Do not call cancelation macros. * sysdeps/posix/sigwait.c (__sigwait): Likewise. * sysdeps/posix/waitid.c (__sigwait): Likewise. * sysdeps/unix/sysdep.h (__SYSCALL_CANCEL_CALL, SYSCALL_CANCEL_NCS): New macro. * sysdeps/nptl/lowlevellock.h (lll_wait_tid): Add timeout argument.

* i386: Remove bogus THREAD_ATOMIC_* macrosAdhemerval Zanella2019-01-032-37/+3
| | | | | | | | | | | | | | | | | | | | The x86 defines optimized THREAD_ATOMIC_* macros where reference always the current thread instead of the one indicated by input 'descr' argument. It work as long the input is the self thread pointer, however it generates wrong code if the semantic is to set a bit atomicialy from another thread. This is not an issue for current GLIBC usage, however the new cancellation code expects that some synchronization code to atomically set bits from different threads. If some usage indeed proves to be a hotspot we can add an extra macro with a more descriptive name (THREAD_ATOMIC_BIT_SET_SELF for instance) where i386 might optimize it. Checked on i686-linux-gnu. * sysdeps/i686/nptl/tls.h (THREAD_ATOMIC_CMPXCHG_VAL, THREAD_ATOMIC_AND, THREAD_ATOMIC_BIT_SET): Remove macros.

* nptl: Fix testcases for new pthread cancellation mechanismAdhemerval Zanella2019-01-033-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | | With upcoming fix for BZ#12683, pthread cancellation does not act for: 1. If syscall is blocked but with some side effects already having taken place (e.g. a partial read or write). 2. After the syscall has returned. The main change is due the fact programs need to act in syscalls with side-effects (for instance, to avoid leak of allocated resources or handle partial read/write). This patch changes the NPTL testcase that assumes the old behavior and also changes the tst-backtrace{5,6} to ignore the cancellable wrappers. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, powerpc-linux-gnu, sparcv9-linux-gnu, and sparc64-linux-gnu. * debug/tst-backtrace5.c (handle_signal): Avoid cancellable wrappers in backtrace analysis. * nptl/tst-cancel4.c (tf_write): Handle cancelled syscall with side-effects. (tf_send): Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | With upcoming BZ#12683 fix, syscall cancellation is not more handled by {libc,pthread,librt}_{enable,disable}_asynccancel symbols. This renders both LIBC_CANCEL_HANDLED and empty declaration and tst-cancel-wrappers.sh unrequired. This patch removes both the macro and the nptl test.

* posix: Clear close-on-exec for posix_spawn adddup2 (BZ#23640)Adhemerval Zanella2019-01-034-14/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Austin Group issue #411 [1] proposes that posix_spawn file action posix_spawn_file_actions_adddup2 resets the close-on-exec when source and destination refer to same file descriptor. It solves the issue on multi-thread applications which uses close-on-exec as default, and want to hand-chose specifically file descriptor to purposefully inherited into a child process. Current approach to achieve this scenario is to use two adddup2 file actions and a temporary file description which do not conflict with any other, coupled with a close file action to avoid leaking the temporary file descriptor. This approach, besides being complex, may fail with EMFILE/ENFILE file descriptor exaustion. This can be more easily accomplished with an in-place removal of FD_CLOEXEC. Although the resulting adddup2 semantic is slight different than dup2 (equal file descriptors should be handled as no-op), the proposed possible solution are either more complex (fcntl action which a limited set of operations) or results in unrequired operations (dup3 which also returns EINVAL for same file descriptor). Checked on aarch64-linux-gnu. [BZ #23640] * posix/tst-spawn.c (do_prepare, handle_restart, do_test): Add posix_spawn_file_actions_adddup2 test to check O_CLOCEXEC reset. * sysdeps/unix/sysv/linux/spawni.c (__spawni_child): Add close-on-exec reset for adddup2 file action. * sysdeps/posix/spawni.c (__spawni_child): Likewise.

* Use C99-compliant scanf under _GNU_SOURCE with modern compilers.Zack Weinberg2019-01-0343-103/+682
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only difference between noncompliant and C99-compliant scanf is that the former accepts the archaic GNU extension '%as' (also %aS and %a[...]) meaning to allocate space for the input string with malloc. This extension conflicts with C99's use of %a as a format _type_ meaning to read a floating-point number; POSIX.1-2008 standardized equivalent functionality using the modifier letter 'm' instead (%ms, %mS, %m[...]). The extension was already disabled in most conformance modes: specifically, any mode that doesn't involve _GNU_SOURCE and _does_ involve either strict conformance to C99 or loose conformance to both C99 and POSIX.1-2001 would get the C99-compliant scanf. With compilers new enough to use -std=gnu11 instead of -std=gnu89, or equivalent, that includes the default mode. With this patch, we now provide C99-compliant scanf in all configurations except when _GNU_SOURCE is defined *and* __STDC_VERSION__ or __cplusplus (whichever is relevant) indicates C89/C++98. This leaves the old scanf available under e.g. -std=c89 -D_GNU_SOURCE, but removes it from e.g. -std=gnu11 -D_GNU_SOURCE (it was already not present under -std=gnu11 without -D_GNU_SOURCE) and from -std=gnu89 without -D_GNU_SOURCE. There needs to be an internal override so we can compile the noncompliant scanf itself. This is the same problem we had when we removed 'gets' from _GNU_SOURCE and it's dealt with the same way: there's a new __GLIBC_USE symbol, DEPRECATED_SCANF, which defaults to off under the appropriate conditions for external code, but can be overridden by individual files within stdio. We also run into problems with PLT bypass for internal uses of sscanf, because libc_hidden_proto uses __REDIRECT and so does the logic in stdio.h for choosing which implementation of scanf to use; __REDIRECT isn't transitive, so include/stdio.h needs to bridge the gap with a macro. As far as I can tell, sscanf is the only function in this family that's internally called by unrelated code. Finally, there are several tests in stdio-common that use the extension. bug21.c is a regression test for a crash; it still exercises the relevant code when changed to use %ms instead of %as. scanf14.c through scanf17.c are more complicated since they are actually testing the subtleties of the extension - under what circumstances is 'a' treated as a modifier letter, etc. I changed all of them to use %ms instead of %as as well, but duplicated scanf14.c and scanf16.c as scanf14a.c and scanf16a.c. These still use %as and are compiled with -std=gnu89 to access the old extension. A bunch of diagnostic overrides and manual workarounds for the old stdio.h behavior become unnecessary. Yay! * include/features.h (__GLIBC_USE_DEPRECATED_SCANF): New __GLIBC_USE parameter.

* ARM: fix kernel assisted atomics with GCC 8 (bug 24034)Aurelien Jarno2019-01-022-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pre-ARMv7 CPUs are missing atomic compare and exchange and/or barrier instructions. Therefore those are implemented using kernel assistance, calling a kernel function at a specific address, and passing the arguments in the r0 to r4 registers. This is done by specifying registers for local variables. The a_ptr variable is placed in the r2 register and declared with __typeof (mem). According to the GCC documentation on local register variables, if mem is a constant pointer, the compiler may substitute the variable with its initializer in asm statements, which may cause the corresponding operand to appear in a different register. This happens in __libc_start_main with the pointer to the thread counter for static binaries (but not the shared ones): # ifdef SHARED unsigned int *ptr = __libc_pthread_functions.ptr_nthreads; # ifdef PTR_DEMANGLE PTR_DEMANGLE (ptr); # endif # else extern unsigned int __nptl_nthreads __attribute ((weak)); unsigned int *const ptr = &__nptl_nthreads; # endif This causes static binaries using threads to crash when the GNU libc is built with GCC 8 and most notably tst-cancel21-static. To fix that, use the same trick than for the volatile qualifier, defining a_ptr as a union. Changelog: [BZ #24034] * sysdeps/unix/sysv/linux/arm/atomic-machine.h (__arm_assisted_compare_and_exchange_val_32_acq): Use uint32_t rather than __typeof (...) for the a_ptr variable.
* Set behavior of sprintf-like functions with overlapping source and destinationGabriel F. T. Gomes2019-01-028-4/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to ISO C99, passing the same buffer as source and destination to sprintf, snprintf, vsprintf, or vsnprintf has undefined behavior. Until the commit commit 4e2f43f842ef5e253cc23383645adbaa03cedb86 Author: Zack Weinberg <zackw@panix.com> Date: Wed Mar 7 14:32:03 2018 -0500 Use PRINTF_FORTIFY instead of _IO_FLAGS2_FORTIFY (bug 11319) a call to sprintf or vsprintf with overlapping buffers, for instance vsprintf (buf, "%sTEXT", buf), would append `TEXT' into buf, while a call to snprintf or vsnprintf would override the contents of buf. After the aforementioned commit, the behavior of sprintf and vsprintf changed (so that they also override the contents of buf). This patch reverts this behavioral change, because it will likely break applications that rely on the previous behavior, even though it is undefined by ISO C. As noted by Szabolcs Nagy, this is used in SPEC2017 507.cactuBSSN_r/src/PUGH/PughUtils.c: sprintf(mess," Size:"); for (i=0;i<dim+1;i++) { sprintf(mess,"%s %d",mess,pughGH->GFExtras[dim]->nsize[i]); } More important to notice is the fact that the overwriting of the destination buffer is not the only behavior affected by the refactoring. Before the refactoring, sprintf and vsprintf would use _IO_str_jumps, whereas __sprintf_chk and __vsprintf_chk would use _IO_str_chk_jumps. After the refactoring, all use _IO_str_chk_jumps, which would make sprintf and vsprintf report buffer overflows and terminate the program. This patch also reverts this behavior, by installing the appropriate jump table for each *sprintf functions. Apart from reverting the changes, this patch adds a test case that has the old behavior hardcoded, so that regressions are noticed if something else unintentionally changes the behavior. Tested for powerpc64le.

All time formats come from CLDR but this commit introduces as few changes as possible (for example, it tries not to change the time zone display). For the locales which are not supported by CLDR the consistency with similar locales (which means the same language or the same country) has been preserved: if the time formats were the same before the change then they are still the same after the change. The time format updates can be roughly summarized as follows: * Most of the locales of Djibouti, Eritrea, and Ethiopia now use "%l:%M:%S %p". * Most of the locales of India and some surrounding countries (Bangladesh, Nepal etc.) now use "%I:%M:%S %p %Z". * Most of the Arabic locales now use "%Z %I:%M:%S %p". * Ge'ez language (Eritrea and Ethiopia) now uses "%l:%M:%S፡%p" (note the consistent use of Ethiopic wordspace character). * Tamil (India) now uses "%p %I:%M:%S %Z". * Chinese (Hong Kong) t_fmt now uses "%p %I<U6642>%M<U5206>%S<U79D2> %Z". * Additionally, the following locales have been switched from 12-hour time formats to 24-hour, according to CLDR: Arabic (Morocco), Maltese, Somali (Kenya), and Tamil (Sri Lanka). * Finally, the Bulgarian, Czech, and Slovak locales used 24-hour time format correctly but their t_fmt_ampm field was not empty containing 12-hour time format which was incorrect so it is now replaced with an empty string.

* sq_AL: Use the correct date and time formats (bug 10496, 23724).Rafal Luzynski2018-12-282-4/+17
| | | | | | | | | | | | | | | | | | | | | Albanian locale uses the 12-hour clock but some time formats did not use any AM/PM indicator making the time ambiguous. This commit adds "%p" wherever it was missing. It also sets the correct date format because the old "%Y-%b-%d" produced rather weird results like "2018-Sht-28". All time formats come from CLDR but as few changes have been introduced by this commit as possible. Some articles from MSDN and other available online sources have been also taken into account. [BZ #10496] [BZ #23724] * localedata/locales/sq_AL (t_fmt): Set to "%I:%M:%S.%p %Z". (t_fmt_ampm): Likewise. (d_t_fmt): Set to "%a %-d %b %Y %I:%M:%S.%p". (date_fmt): Add, set to "%a %-d %b %Y %I:%M:%S.%p %Z". (d_fmt): Set to "%-d.%-m.%y".
