* Add jmp_buf-macros.h for no-FPU ColdFire.Joseph Myers2018-01-243-0/+13
| | | | | | | | | | | | | | | Continuing the fixes for ColdFire glibc build with build-many-glibcs.py, given a GCC patch for the libgcc build failure, this patch adds jmp_buf-macros.h for no-FPU ColdFire. This allows the no-FPU build to progress further than without the patch (although other fixes are still needed for the build to complete). * sysdeps/unix/sysv/linux/m68k/coldfire/jmp_buf-macros.h: Move to .... * sysdeps/unix/sysv/linux/m68k/coldfire/fpu/jmp_buf-macros.h: ... here. * sysdeps/unix/sysv/linux/m68k/coldfire/nofpu/jmp_buf-macros.h: New file.
* Add jmp_buf-macros.h for ColdFire.Joseph Myers2018-01-243-0/+13
| | | | | | | | | | | | | | | | | | | | | | This patch adds a jmp_buf-macros.h for ColdFire. In conjunction with a GCC patch to fix the libgcc build failure for ColdFire <https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02064.html> this suffices to restore the build (tested with build-many-glibcs.py). A further patch will be needed for soft-float ColdFire (while the function-calling ABI is the same for hard-float and soft-float ColdFire, it turns out the glibc ABI is not - so another ColdFire variant will be needed in build-many-glibcs.py), but I'll deal with that separately. Tested with build-many-glibcs.py (m68k-linux-gnu and m68k-linux-gnu-coldfire). (There's a localplt test failure for coldfire; that's the only failure in the compilation part of the testsuite.) * sysdeps/unix/sysv/linux/m68k/jmp_buf-macros.h: Move to .... * sysdeps/unix/sysv/linux/m68k/m680x0/jmp_buf-macros.h: ... here. * sysdeps/unix/sysv/linux/m68k/coldfire/jmp_buf-macros.h: New file.

* Implement alternative month names (bug 10871).Rafal Luzynski2018-01-2213-64/+251
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some languages (Slavic, Baltic, etc.) require a genitive case of the month name when formatting a full date (with the day number) while they require a nominative case when referring to the month standalone. This requirement cannot be fulfilled without providing two forms for each month name. From now it is specified that nl_langinfo(MON_1) series (up to MON_12) and strftime("%B") generate the month names in the grammatical form used when the month is a part of a complete date. If the grammatical form used when the month is named by itself is needed, the new values nl_langinfo(ALTMON_1) (up to ALTMON_12) and strftime("%OB") are supported.

* powerpc: Fix syscalls during early process initialization [BZ #22685]Tulio Magno Quites Machado Filho2018-01-194-4/+47
| | | | | | | | | | | | | | | | | | | | | | | | | The tunables framework needs to execute syscall early in process initialization, before the TCB is available for consumption. This behavior conflicts with powerpc{|64|64le}'s lock elision code, that checks the TCB before trying to abort transactions immediately before executing a syscall.

* Fix integer overflows in internal memalign and malloc functions [BZ #22343]Arjun Shankar2018-01-184-8/+286
| | | | | | | | | | | | | | | | | | | | | | | | When posix_memalign is called with an alignment less than MALLOC_ALIGNMENT and a requested size close to SIZE_MAX, it falls back to malloc code (because the alignment of a block returned by malloc is sufficient to satisfy the call). In this case, an integer overflow in _int_malloc leads to posix_memalign incorrectly returning successfully. Upon fixing this and writing a somewhat thorough regression test, it was discovered that when posix_memalign is called with an alignment larger than MALLOC_ALIGNMENT (so it uses _int_memalign instead) and a requested size close to SIZE_MAX, a different integer overflow in _int_memalign leads to posix_memalign incorrectly returning successfully. Both integer overflows affect other memory allocation functions that use _int_malloc (one affected malloc in x86) or _int_memalign as well. This commit fixes both integer overflows. In addition to this, it adds a regression test to guard against false successful allocations by the following memory allocation functions when called with too-large allocation sizes and, where relevant, various valid alignments: malloc, realloc, calloc, reallocarray, memalign, posix_memalign, aligned_alloc, valloc, and pvalloc.

* Fix backtrace for hppa (bug 22719).Joseph Myers2018-01-172-0/+6
| | | | | | | | | | | | | | | | | | | The only architecture in glibc that uses the generic debug/backtrace.c is hppa. The debug/tst-backtrace* tests fail for hppa, so in fact the generic debug/backtrace.c is not functional anywhere. Instead, the x86_64 version is a reasonably generic version that uses _Unwind_Backtrace from libgcc to backtrace using unwind info, and is used by several architectures. This patch adds hppa to the architectures using it (leaving open the possibility of a subsequent cleanup for 2.28 of moving the x86_64 version to debug/backtrace.c, and removing all the frame.h files that are now unused). Reported by Adhemerval in <https://sourceware.org/ml/libc-alpha/2018-01/msg00564.html> that this does fix the backtrace test failures for hppa. [BZ #22719] * sysdeps/hppa/backtrace.c: New file.
* x86-64: Properly align La_x86_64_retval to VEC_SIZE [BZ #22715]H.J. Lu2018-01-172-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | _dl_runtime_profile calls _dl_call_pltexit, passing a pointer to La_x86_64_retval which is allocated on stack. The lrv_vector0 field in La_x86_64_retval must be aligned to size of vector register. When allocating stack space for La_x86_64_retval, we need to make sure that the address of La_x86_64_retval + RV_VECTOR0_OFFSET is aligned to VEC_SIZE. This patch checks the alignment of the lrv_vector0 field and pads the stack space if needed. Tested with x32 and x86-64 on SSE4, AVX and AVX512 machines.

| | | | | | | | | | | | | | | | | In the static pie enabled libc, crt1.o uses the same position independent code as rcrt1.o and crt1.o is used instead of Scrt1.o when -no-pie executables are linked. When main is not defined in the executable, but in a shared library crt1.o is currently broken, it assumes main is local. (glibc has a test for this but i missed it in my previous testing.) To make both rcrt1.o and crt1.o happy with the same code, a wrapper is introduced around main: with this crt1.o works with extern main symbol while rcrt1.o does not depend on GOT relocations. (The change only affects static pie enabled libc. Further simplification of start.S is possible in the future by using the same approach for Scrt1.o too.) * aarch64/start.S (_start): Use __wrap_main.

* linux: make getcwd(3) fail if it cannot obtain an absolute path [BZ #22679]Dmitry V. Levin2018-01-125-5/+84
| | | | | | | | | | | | | | | | | | | | | | | | | Currently getcwd(3) can succeed without returning an absolute path because the underlying getcwd syscall, starting with linux commit v2.6.36-rc1~96^2~2, may succeed without returning an absolute path. This is a conformance issue because "The getcwd() function shall place an absolute pathname of the current working directory in the array pointed to by buf, and return buf". This is also a security issue because a non-absolute path returned by getcwd(3) causes a buffer underflow in realpath(3). Fix this by checking the path returned by getcwd syscall and falling back to generic_getcwd if the path is not absolute, effectively making getcwd(3) fail with ENOENT. The error code is chosen for consistency with the case when the current directory is unlinked. [BZ #22679] CVE-2018-1000001 * sysdeps/unix/sysv/linux/getcwd.c (__getcwd): Fall back to generic_getcwd if the path returned by getcwd syscall is not absolute. * io/tst-getcwd-abspath.c: New test. * io/Makefile (tests): Add tst-getcwd-abspath.

* Fix s390 linknamespace fallout of bug 22702 patch.Joseph Myers2018-01-122-1/+6
| | | | | | | | | | | | | | | My fix for bug 22702 introduced linknamespace test failures on s390x-linux-gnu and s390-linux-gnu because it made remainder call __feholdexcept, and the s390 __feholdexcept calls fegetenv, and remainder is in Unix98 and XPG4.2 but fegetenv isn't. This patch makes __feholdexcept call __fegetenv instead to avoid that namespace issue. Tested (compilation) with build-many-glibcs.py for s390x-linux-gnu, where it resolves the test failures. * sysdeps/s390/fpu/feholdexcpt.c (__feholdexcept): Call __fegetenv instead of fegetenv.
* Make default libc_feholdsetround_noex_ctx use __feholdexcept (bug 22702).Joseph Myers2018-01-112-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For soft-float powerpc, the math/test-nearbyint-except-2 test fails because nearbyintl traps when traps on "inexact" are enabled on entry (and an "inexact" exception is generated internally, though cleared for the final return). The problem is the default implementation of libc_feholdsetround_noex_ctx, which does not disable exception traps. There is some ambiguity about whether the *noex* interfaces are required to do so or only permitted to do so. But given that we support fe* interfaces to enable and disable traps (on architectures with that functionality), functions that must not raise an exception (must not leave the flag set on exit if not set on entry) should also not trap on it when traps on that exception are enabled. So it is appropriate to define these interfaces to have the feholdexcept effect of disabling exception traps; this patch updates the default implementation and comments accordingly. At least some architecture versions already disable traps; there are few uses of the *noex* interfaces at all, and while it's possible there are bugs on any architecture versions failing to disable traps that appear in the exp2 and remainder implementations, there are currently no tests, other than this one for nearbyintl (where only the ldbl-128ibm implementation uses SET_RESTORE_ROUND_NOEX), that would fail as a result of such a bug. (Hard-float powerpc does disable traps here, hence the nearbyintl failure not appearing there.) Tested for powerpc (soft-float). This brings that configuration to clean math/ test results, provided you build with GCC 8 to get the fix for GCC bug 64811. [BZ #22702] * sysdeps/generic/math_private.h (libc_feresetround_noex): Update comment to say exceptions are discarded. (libc_feholdsetround_noex_ctx): Use __feholdexcept instead of __fegetenv. (SET_RESTORE_ROUND_NOEX): Update comment to say non-stop mode must be enabled.

* Fix ldbl-128ibm log1pl (-qNaN) spurious "invalid" exception (bug 22693).Joseph Myers2018-01-102-2/+8
| | | | | | | | | | | | | | | The ldbl-128ibm implementation of log1pl does ordered comparisons on a negative qNaN argument, so resulting in spurious "invalid" exceptions (for soft-float powerpc; hard-float only avoids this because of GCC bug 58684 meaning ordered comparison instructions never get generated). This patch fixes this by arranging for the test for NaN or infinity arguments to handle negative arguments as well. Tested for powerpc (soft float). [BZ #22693] * sysdeps/ieee754/ldbl-128ibm/s_log1pl.c (__log1pl): Handle negative arguments in test for NaN or infinity argument.

| | | | | | | | | Disabling lazy binding reduces stack usage during unwinding. Note that RTLD_NOW only makes a difference if libgcc.so has not already been loaded, so this is only a partial fix. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
