* Update Linux kernel version in tst-mman-consts.py.Joseph Myers2019-01-022-1/+4
| | | | | | | | | | | | | | | This patch updates the Linux kernel version in tst-mman-consts.py to 4.20 (meaning that's the version for which glibc is expected to have the same constants as the kernel, up to the exceptions listed in the test). (Once we have more such tests sharing common infrastructure, I expect the kernel version will be something set in the infrastructure shared by all such tests, rather than something needing updating separately for each test for each new kernel version.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Expect constants to match with Linux 4.20.

* 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.

| | | | | | | | This commit removes the custom memcpy implementation from _int_realloc for small chunk sizes. The ncopies variable has the wrong type, and an integer wraparound could cause the existing code to copy too few elements (leaving the new memory region mostly uninitialized).

It also broke glibc in a different way: asm/syscalls.h is being used by glibc. I noticed this while doing Fedora 30/Rawhide mass rebuild. The patch returns asm/syscalls.h header and incl. it into asm/unistd.h. I plan to send a patch to glibc to use asm/unistd.h instead of asm/syscalls.h In the meantime, we use __has_include__, which was added to GCC 5, to check if <asm/syscalls.h> exists before including it.

This commit adds "%p" wherever it was missing. In some cases it has been identified that a locale should use 24-hour time format rather than 12-hour. 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.

| | | | | | | | | | | | | | | | | | | | | 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".

* Update nios2, sparc32 localplt.data for difftime changes (bug 24023).Joseph Myers2018-12-213-0/+11
| | | | | | | | | | | | | | | | | | | | | | The recent difftime changes introduced localplt test failures on nios2 and sparc32, two configurations where some soft-fp functions are defined in / exported from libc.so, and where the difftime changes affected the particular set of floating-point operations used in libc.so. This patch adds those functions to localplt.data, alongside other such functions already there. (In the sparc32 case, and more generally on any platform where long double is a software floating-point type, it would probably be more efficient to avoid using long double at all in difftime, but that's a pre-existing issue.) Tested with build-many-glibcs.py for its nios2 and sparcv9 configurations.

| | | | | | | | | | | | | This patch updates longlong.h from GCC.

Tested for x86_64 and x86. Also tested with build-many-glibcs.py for its RISC-V configurations, as the glibc architecture with the most substantial changes in longlong.h in this patch. * stdlib/longlong.h: Update from GCC.
* Require GCC 5 or later to build glibc (bug 23993).Joseph Myers2018-12-216-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | We know that building glibc with GCC 4.9 is broken on various platforms (bug 23993). As it's more than a year since we last increased the minimum GCC version to build glibc, this patch changes the requirement to be GCC 5 or later (indeed, based on 4.9 having been required for building 2.26, it would be consistent in terms of timing to require GCC 6 or later from the 2.30 release onwards). It deliberately just updates the configure test and corresponding documentation, leaving removal of no-longer-needed __GNUC_PREREQ tests for a separate patch. In the NEWS entry, the requirement for a newer GCC version for powerpc64le is reiterated (as in the entry for the 4.9 requirement in 2.26) to avoid suggesting the version requirement there has gone down. (If that version goes up further as part of support for binary128 long double, of course the wording would change at that time.) Tested for x86_64.

* Y2038: make __difftime compatible with 64-bit timeAlbert ARIBAUD (3ADEV)2018-12-203-9/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a 64-bit-time version of __difftime (but do not assume __time64_t is a signed int so that Gnulib can reuse the code) and make the 32-bit version a wrapper of it. Current difftime expects two time_t arguments and returns a double. To preserve source-code compatibility, its 64-bit-time equivalent expects two __time64_t arguments but still returns a double. This patch was tested by running 'make check' on branch master then applying this patch and its two predecessors and running 'make check' again, and checking that both 'make check' yield identical results. This was done on x86_64-linux-gnu and i686-linux-gnu. This patch was also functionally tested with an ad hoc userland C program which checks the result of difftime for various pairs of 32-bit and, for 64-bit builds, of 64-bit time_t values too.

* Remove x86 mathinline.h.Joseph Myers2018-12-193-295/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | After previous cleanups, the only code in the x86 bits/mathinline.h that is relevant with current compilers is the inline of __ieee754_atan2l that is conditional on __LIBC_INTERNAL_MATH_INLINES (i.e. for when libm itself is being built). This inline is something that does belong in glibc not GCC, since __ieee754_atan2l is a purely internal function name. This patch moves that inline to a new sysdeps/x86/fpu/math_private.h, removing the bits/mathinline.h header. Note that previously the inline was only for non-SSE 32-bit x86. That condition does not make sense, however, for a long double function; if it's not inlined, exactly the same x87 instruction will end up getting used by the out-of-line function, for both 32-bit and 64-bit. So that condition is not retained in the new version. Tested for x86_64 and x86. As expected, installed stripped shared libraries are unchanged for 32-bit x86, but installed stripped libm.so is changed for x86_64 because calls to __ieee754_atan2l start being inlined where previously they were out of line calls. (The same change to start inlining the function would presumably also apply for 32-bit built with -mfpmath=sse, but that's not a configuration I've tested.) * sysdeps/x86/fpu/math_private.h: New file. * sysdeps/x86/fpu/bits/mathinline.h: Remove.
* Remove x86 mathinline.h sinh, cosh, tanh inlines.Joseph Myers2018-12-192-16/+7
| | | | | | | | | | | | | | | | | | | | | | Continuing the removal of bits/mathinline.h inlines that would better be done by the compiler, this patch removes x86 inlines for sinh, cosh and tanh functions (inlines only previously present for fast-math, non-SSE 32-bit x86). I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88556> for adding such inlines as an optimization in GCC. I believe the only remaining part of the x86 bits/mathinline.h that does anything useful with current compilers after this patch is the __LIBC_INTERNAL_MATH_INLINES inline of __ieee754_atan2l; I intend to remove the whole header and move that inline to a sysdeps math_private.h header in a subsequent patch. Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h (sinh): Remove inline definition. (cosh): Likewise. (tanh): Likewise.
* Print cache size and geometry auxv types on LD_SHOW_AUXV=1Tulio Magno Quites Machado Filho2018-12-193-31/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE, AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY when LD_SHOW_AUXV=1. AT_L*_CACHESIZE is printed as decimal and represent the number of bytes of the cache. AT_L*_CACHEGEOMETRY is treated in order to specify the cache line size and its associativity. Example output from a POWER8: AT_L1I_CACHESIZE: 32768 AT_L1I_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L1D_CACHESIZE: 65536 AT_L1D_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L2_CACHESIZE: 524288 AT_L2_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L3_CACHESIZE: 8388608 AT_L3_CACHEGEOMETRY: 128B line size, 8-way set associative Some of the new types are longer than the previous ones, requiring to increase the indentation in order to keep the values aligned. * elf/dl-sysdep.c (auxvars): Add AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE, AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY. Fix indentation when printing the other fields. (_dl_show_auxv): Give a special treatment to AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY. * sysdeps/powerpc/dl-procinfo.h (cache_geometry): New function. (_dl_procinfo): Fix indentation when printing AT_HWCAP and AT_HWCAP2. Add support for AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY.
