* ldconfig/x86: Store ISA level in cache and aux cacheH.J. Lu2021-01-131-10/+12
| | | | | | | | | | | Store ISA level in the portion of the unused upper 32 bits of the hwcaps field in cache and the unused pad field in aux cache. ISA level is stored and checked only for shared objects in glibc-hwcaps subdirectories. The shared objects in the default directories aren't checked since there are no fallbacks for these shared objects. Tested on x86-64-v2, x86-64-v3 and x86-64-v4 machines with --disable-hardcoded-path-in-tests and --enable-hardcoded-path-in-tests.

| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

The outliers are alpha, where its kernel ABI explict return -ENOMEM in case of failure; and i686, where it can't use "call *%gs:SYSINFO_OFFSET" during statup in static PIE. Also some ABIs exports an additional ___brk_addr symbol and to handle it an internal HAVE_INTERNAL_BRK_ADDR_SYMBOL is added.

* Linux: Remove rseq supportFlorian Weimer2020-07-161-1/+0
| | | | | | | | | | | | | | | | | | The kernel ABI is not finalized, and there are now various proposals to change the size of struct rseq, which would make the glibc ABI dependent on the version of the kernels used for building glibc. This is of course not acceptable.

Instead of include a generic header (bits/signum-generic.h) and undef non-default values in an arch specific header (bits/signum.h) the new scheme uses a common definition (bits/signum-generic.h) and each architectures add its specific definitions on a new header (bits/signum-arch.h). For Linux it requires copy some system default definitions to alpha, hppa, and sparc. They are historical values and newer ports uses the generic Linux signum-arch.h.

* Add the __libc_single_threaded variableFlorian Weimer2020-07-061-0/+1
| | | | | | | | | | | | | | The variable is placed in libc.so, and it can be true only in an outer libc, not libcs loaded via dlmopen or static dlopen. Since thread creation from inner namespaces does not work, pthread_create can update __libc_single_threaded directly.

A future version may reset the flag during fork (but not in an inner namespace), or after joining all threads except one. Reviewed-by: DJ Delorie <dj@redhat.com>
* Linux: Perform rseq registration at C startup and thread creationMathieu Desnoyers2020-07-061-0/+1
| | | | | | | | | | | | | | | | | | | Register rseq TLS for each thread (including main), and unregister for each thread (excluding main). "rseq" stands for Restartable Sequences. See the rseq(2) man page proposed here: https://lkml.org/lkml/2018/9/19/647 Those are based on glibc master branch commit 3ee1e0ec5c. The rseq system call was merged into Linux 4.18. The TLS_STATIC_SURPLUS define is increased to leave additional room for dlopen'd initial-exec TLS, which keeps elf/tst-auditmany working. The increase (76 bytes) is larger than 32 bytes because it has not been increased in quite a while. The cost in terms of additional TLS storage is quite significant, but it will also obscure some initial-exec-related dlopen failures.
* New exp10f version without SVID compat wrapperAdhemerval Zanella2020-06-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch changes the exp10f error handling semantics to only set errno according to POSIX rules. New symbol version is introduced at GLIBC_2.32. The old wrappers are kept for compat symbols. There are some outliers that need special handling: - ia64 provides an optimized implementation of exp10f that uses ia64 specific routines to set SVID compatibility. The new symbol version is aliased to the exp10f one. - m68k also provides an optimized implementation, and the new version uses it instead of the sysdeps/ieee754/flt32 one. - riscv and csky uses the generic template implementation that does not provide SVID support. For both cases a new exp10f version is not added, but rather the symbols version of the generic sysdeps/ieee754/flt32 is adjusted instead. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu.

* ld.so: Do not export free/calloc/malloc/realloc functions [BZ #25486]Florian Weimer2020-02-152-10/+0
| | | | | | | | | | | | | | | | | | | Exporting functions and relying on symbol interposition from libc.so makes the choice of implementation dependent on DT_NEEDED order, which is not what some compiler drivers expect. This commit replaces one magic mechanism (symbol interposition) with another one (preprocessor-/compiler-based redirection). This makes the hand-over from the minimal malloc to the full malloc more explicit. Removing the ABI symbols is backwards-compatible because libc.so is always in scope, and the dynamic loader will find the malloc-related symbols there since commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c ("ld.so: Support moving versioned symbols between sonames [BZ #24741]").

* Linux: Use system call tables during buildFlorian Weimer2020-01-025-7/+7
| | | | | | | | | | | | | | | | | | | | | | | Use <arch-syscall.h> instead of <asm/unistd.h> to obtain the system call numbers. A few direct includes of <asm/unistd.h> need to be removed (if the system call numbers are already provided indirectly by <sysdep.h>) or replaced with <sys/syscall.h>. Current Linux headers for alpha define the required system call names, so most of the _NR_* hacks are no longer needed. For the 32-bit arm architecture, eliminate the INTERNAL_SYSCALL_ARM macro, now that we have regular system call names for cacheflush and set_tls. There are more such cleanup opportunities for other architectures, but these cleanups are required to avoid macro redefinition errors during the build. For ia64, it is desirable to use <asm/break.h> directly to obtain the break number for system calls (which is not a system call number itself). This requires replacing __BREAK_SYSCALL with __IA64_BREAK_SYSCALL because the former is defined as an alias in <asm/unistd.h>, but not in <asm/break.h>.

* Linux: Add tables with system call numbersFlorian Weimer2020-01-021-0/+341
| | | | | | | | | | | | | | | | | | | | | | | | | | | The new tables are currently only used for consistency checks with the installed kernel headers and the architecture-independent system call names table. They are based on Linux 5.4. The goal is to use these architecture-specific tables to ensure that system call wrappers are available irrespective of the version of the installed kernel headers. The tables are formatted in the form of C header files so that they can be used directly in an #include directive, without external preprocessing. (External preprocessing of a plain table file would introduce cross-subdirectory dependency issues.) However, the intent is that they can still be treated as tables and can be processed by simple tools. The irregular system call names on 32-bit arm add a complication. The <fixup-asm-unistd.h> header is introduced to work around that, and the system calls are listed under regular names in the <arch-syscall.h> file. A make target, update-syscalls-list, is added to patch the glibc sources with data from the current kernel headers. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
