* aarch64: fix static pie enabled libc when main is in a shared librarySzabolcs Nagy2018-01-122-2/+16
| | | | | | | | | | | | | | | | | 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. (__wrap_main): New local symbol.
* 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.

* hu_HU locale: Avoid double space (bug 22657).Egmont Koblinger2018-01-122-2/+10
| | | | | | | | | | | | | | | | | | | | | | | The current date format prefixes one-digit days with a space, resulting in ugly two spaces: $ LC_ALL=hu_HU.UTF-8 date 2018. jan. 1., hétfő, 21:25:35 CET ^^ The official orthography rules doesn't contain an explicit rule about this (which already gives no sane reason for double space), and an implicit example of "1848. március 9." under bullet point 296 at http://helyesiras.mta.hu/helyesiras/default/akh12 contains a single space only.

* 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.

* 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.

* 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).

* Fix ldbl-128ibm lrintl, lroundl missing "invalid" exceptions (bug 22690).Joseph Myers2018-01-103-12/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ldbl-128ibm implementations of lrintl and lroundl are missing "invalid" exceptions for certain overflow cases when compiled with GCC 8. The cause of this is after-the-fact integer overflow checks that fail when the compiler optimizes on the basis of integer overflow being undefined; GCC 8 must be able to detect new cases of undefinedness here. Failure: lrint (-0x80000001p0): Exception "Invalid operation" not set Failure: lrint_downward (-0x80000001p0): Exception "Invalid operation" not set Failure: lrint_towardzero (-0x80000001p0): Exception "Invalid operation" not set Failure: lrint_upward (-0x80000001p0): Exception "Invalid operation" not set Failure: lround (-0x80000001p0): Exception "Invalid operation" not set Failure: lround_downward (-0x80000001p0): Exception "Invalid operation" not set Failure: lround_towardzero (-0x80000001p0): Exception "Invalid operation" not set Failure: lround_upward (-0x80000001p0): Exception "Invalid operation" not set (Tested that these failures occur before the patch for powerpc soft-float, but the issue applies in principle for hard-float as well, whether or not the particular optimizations in fact occur there at present.) This patch fixes the bug by ensuring the additions / subtractions in question cast arguments to unsigned long int, or use 1UL as a constant argument, so that the arithmetic occurs in an unsigned type with the result then converted back to a signed type.

* Fix powerpc-nofpu complex long double functions spurious "invalid" exception ↵Joseph Myers2018-01-092-6/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (bug 22687). For soft-float powerpc, various _Complex long double functions generate spurious "invalid" exceptions, even with a compiler with GCC bug 64811 fixed. The problem is GCC's built-in fabsl expansion. Various files are already built with -fno-builtin-fabsl because in this case (IBM long double, for soft-float or e500v1) a fallback fabsl expansion based on comparisons is used, which can produce the wrong sign of a zero result. Those comparisons can also produce spurious exceptions for NaN arguments. Furthermore, __builtin_fpclassify implemently uses __builtin_fabsl, and is unaffected by -fno-builtin-fabsl, and the fpclassify macro uses __builtin_fpclassify in the absence of -fsignaling-nans. Thus, this patch arranges for the problem files using fpclassify to be built with -fsignaling-nans in this case, to avoid spurious exceptions from fpclassify. Tested for powerpc (soft-float).

* Allow make-link-multidir to make subdirectoriesPalmer Dabbelt2018-01-062-0/+3
| | | | | | | | | | | | | | | The RISC-V Linux ABI doesn't define any libraries that go directly in lib, instead they go into lib32/ilp32 or lib64/lp64. This casuse make-link-multidir to fail when attempting to make library directories when building a static libc on multilib RISC-V systems. This patch uses scripts/mkinstalldirs to make the base directory of the target symlink of make-link-multidir. 2018-01-06 Palmer Dabbelt <palmer@sifive.com> * Makerules (make-link-multidir): Make directories before linking into them.
* Add RISC-V dynamic relocations to elf.hPalmer Dabbelt2018-01-062-0/+29

| | | | | | | | | | | | The function _itoa_word() writes characters from the higher address to the lower address, requiring the destination string to reserve that size before calling it. * sysdeps/powerpc/powerpc64/dl-machine.c (_dl_reloc_overflow): Reserve 16 chars to reloc_addr before calling _itoa_word.
