* struct _Unwind_Exception alignment should not depend on compiler flagsFlorian Weimer2020-11-111-9/+15
| | | | | | | | | | | | __attribute__((__aligned__)) selects an alignment that depends on the micro-architecture selected by GCC flags. Enabling vector extensions may increase the allignment. This is a problem when building glibc as a collection of ELF multilibs with different GCC flags because ld.so and libc.so/libpthread.so/&c may end up with a different layout of struct pthread because of the changing offset of its struct _Unwind_Exception field.

* hurd: keep only required PLTs in ld.soSamuel Thibault2020-11-117-26/+6
| | | | | | | | | | | | | | | | | | | | | We need NO_RTLD_HIDDEN because of the need for PLT calls in ld.so. See Roland's comment in https://sourceware.org/bugzilla/show_bug.cgi?id=15605 "in the Hurd it's crucial that calls like __mmap be the libc ones instead of the rtld-local ones after the bootstrap phase, when the dynamic linker is being used for dlopen and the like." We used to just avoid all hidden use in the rtld ; this commit switches to keeping only those that should use PLT calls, i.e. essentially those defined in sysdeps/mach/hurd/dl-sysdep.c: __assert_fail __assert_perror_fail __*stat64 _exit This fixes a few startup issues, notably the call to __tunable_get_val that is made before PLTs are set up.

* aarch64: Add variant PCS lazy binding test [BZ #26798]Szabolcs Nagy2020-11-025-0/+288
| | | | | | | | | | | This test fails without bug 26798 fixed because some integer registers likely get clobbered by lazy binding and variant PCS only allows x16 and x17 to be clobbered at call time. The test requires binutils 2.32.1 or newer for handling variant PCS symbols. SVE registers are not covered by this test, to avoid the complexity of handling multiple compile- and runtime feature support cases.
* aarch64: Fix DT_AARCH64_VARIANT_PCS handling [BZ #26798]Szabolcs Nagy2020-11-021-8/+4
| | | | | | | | | | | | | The variant PCS support was ineffective because in the common case linkmap->l_mach.plt == 0 but then the symbol table flags were ignored and normal lazy binding was used instead of resolving the relocs early. (This was a misunderstanding about how GOT[1] is setup by the linker.) In practice this mainly affects SVE calls when the vector length is more than 128 bits, then the top bits of the argument registers get clobbered during lazy binding. Fixes bug 26798.

* Avoid -Wstringop-overflow warning in pthread_cleanup_push macrosJoseph Myers2020-10-301-10/+27
| | | | | | | | | | | | | | | | | | | | | GCC 11 introduces a -Wstringop-overflow warning for calls to functions with an array argument passed as a pointer to memory not large enough for that array. This includes the __sigsetjmp calls from pthread_cleanup_push macros, because those use a structure in __pthread_unwind_buf_t, which has a common initial subsequence with jmp_buf but does not include the saved signal mask; this is OK in this case because the second argument to __sigsetjmp is 0 so the signal mask is not accessed. To avoid this warning, use a function alias __sigsetjmp_cancel with first argument an array of exactly the type used in the calls to the function, if using GCC 11 or later. With older compilers, continue to use __sigsetjmp with a cast, to avoid any issues with compilers predating the returns_twice attribute not applying the same special handling to __sigsetjmp_cancel as to __sigsetjmp. Tested with build-many-glibcs.py for arm-linux-gnueabi that this fixes the testsuite build failures.

* y2038: nptl: Provide __futex_clock_wait_bitset64 to support 64 bit bitsetLukasz Majewski2020-10-212-1/+52
| | | | | | | | | | | | | | | The commit: "y2038: nptl: Convert pthread_mutex_{clock|timed}lock to support 64 bit" SHA1: 29e9874a048f47e2d46c40253036c8d2de921548 introduced support for 64 bit timeouts. Unfortunately, it was missing the code for bitset - i.e. lll_futex_clock_wait_bitset C preprocessor macro was used. As a result the 64 bit struct __timespec64 was coerced to 32 bit struct timespec and regression visible as timeout was observed (nptl/tst-robust10 on s390).

* C-SKY: Make dynamic linker's name compitable with the older gcc.Cooper Qu2020-10-211-9/+26
| | | | | | | | | | | | | | __CSKY_HARD_FLOAT_ABI__ was added on gcc 11 to specify whether -mfloat-abi=hard is set. On older gcc, the float ABI is defined solely with __CSKY_HARD_FLOAT__. If __CSKY_HARD_FLOAT__ is set, it can be either a hard-float ABI (gcc older than 11, or gcc11 -mfloat-abi=hard (__CSKY_HARD_FLOAT_ABI__ is set) or -mfloat-abi=softfp (__CSKY_HARD_FLOAT_ABI__ is not set). To be compatible with older gcc, use __CSKY_HARD_FLOAT_FPU_SF__ identify if -mfloat-abi is supported, because it is added to gcc at the same time as -mfloat-abi.

* Move vtimes to a compatibility symbolAdhemerval Zanella2020-10-191-1/+0
| | | | | | | | | | | | | | I couldn't pinpoint which standard has added it, but no other POSIX system supports it and/or no longer provide it. The 'struct vtimes' also has a lot of drawbacks due its limited internal type size. I couldn't also see find any project that actually uses this symbol, either in some dignostic way (such as sanitizer). So I think it should be safer to just move to compat symbol, instead of deprecated. The idea it to avoid new ports to export such broken interface (riscv32 for instance). Checked on x86_64-linux-gnu and i686-linux-gnu.
* y2038: linux: Provide __time64 implementationLukasz Majewski2020-10-193-3/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the glibc the time function can use vDSO (on power and x86 the USE_IFUNC_TIME is defined), time syscall or 'default' time() from ./time/time.c (as a fallback). In this patch the last function (time) has been refactored and moved to ./sysdeps/unix/sysv/linux/time.c to be Linux specific. The new __time64 explicit 64 bit function for providing 64 bit value of seconds after epoch (by internally calling __clock_gettime64) has been introduced. Moreover, a 32 bit version - __time has been refactored to internally use __time64. The __time is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary check for time_t potential overflow. The iFUNC vDSO direct call optimization has been removed from both i686 and powerpc32 (USE_IFUNC_TIME is not defined for those architectures anymore). The Linux kernel does not provide a y2038 safe implementation of time neither it plans to provide it in the future, __clock_gettime64 should be used instead. Keeping support for this optimization would require to handle another build permutation (!__ASSUME_TIME64_SYSCALLS && USE_IFUNC_TIME which adds more complexity and has limited use (since the idea is to eventually have a y2038 safe glibc build).

* x86: Initialize CPU info via IFUNC relocation [BZ 26203]H.J. Lu2020-10-169-865/+949
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | X86 CPU features in ld.so are initialized by init_cpu_features, which is invoked by DL_PLATFORM_INIT from _dl_sysdep_start. But when ld.so is loaded by static executable, DL_PLATFORM_INIT is never called. Also x86 cache info in libc.o and libc.a is initialized by a constructor which may be called too late. Since some fields in _rtld_global_ro in ld.so are initialized by dynamic relocation, we can also initialize x86 CPU features in _rtld_global_ro in ld.so and cache info in libc.so by initializing dummy function pointers in ld.so and libc.so via IFUNC relocation. Key points: 1. IFUNC is always supported, independent of --enable-multi-arch or --disable-multi-arch. Linker generates IFUNC relocations from input IFUNC objects and ld.so performs IFUNC relocations. 2. There are no IFUNC dependencies in ld.so before dynamic relocation have been performed, 3. The x86 CPU features in ld.so is initialized by DL_PLATFORM_INIT in dynamic executable and by IFUNC relocation in dlopen in static executable. 4. The x86 cache info in libc.o is initialized by IFUNC relocation. 5. In libc.a, both x86 CPU features and cache info are initialized from ARCH_INIT_CPU_FEATURES, not by IFUNC relocation, before __libc_early_init is called. Note: _dl_x86_init_cpu_features can be called more than once from DL_PLATFORM_INIT and during relocation in ld.so.

The __lll_lock_elision (aliased to __lll_clocklock_elision in e.g. sysdeps/unix/sysv/linux/s390/elision-timed.c) just uses, in this patch provided, __futex_clocklock64.

* linux: Move {f}xstat{at} to compat symbolsAdhemerval Zanella2020-10-0921-31/+181
| | | | | | | | | | | They are no interna uses anymore. The riscv32 ABI was added on 2.33, so it is safe to remove the old __{f,l}stat{at} symbols and just provide the newer {f,l}stat{at} ones. Checked with a build for all affected ABIs. I also checked on x86_64, i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x. Reviewed-by: Lukasz Majewski <lukma@denx.de>
