* Remove mknod wrapper functions, move them to symbolsAdhemerval Zanella2020-10-091-0/+2
| | | | | | | | | | | | | | | | | | | This patch removes the mknod and mknodat static wrapper and add the symbols on the libc with the expected names. Both the prototypes of the internal symbol linked by the static wrappers and the inline redirectors are also removed from the installed sys/stat.h header file. The wrapper implementation license LGPL exception is also removed since it is no longer statically linked to binaries. Internally the _STAT_VER* definitions are moved to the arch-specific xstatver.h file. 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>

* Linux: Remove rseq supportFlorian Weimer2020-07-162-44/+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. This reverts commit 48699da1c468543ade14777819bd1b4d652709de ("elf: Support at least 32-byte alignment in static dlopen"), commit 8f4632deb3545b2949cec5454afc3cb21a0024ea ("Linux: rseq registration tests"), commit 6e29cb3f61ff5432c78a1c84b0d9b123a350ab36 ("Linux: Use rseq in sched_getcpu if available"), and commit 0c76fc3c2b346dc5401dc055d97d4279632b0fb3 ("Linux: Perform rseq registration at C startup and thread creation"), resolving the conflicts introduced by the ARC port and the TLS static surplus changes.

* aarch64: enable BTI at runtimeSudakshina Das2020-07-084-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Binaries can opt-in to using BTI via an ELF object file marking. The dynamic linker has to then mprotect the executable segments with PROT_BTI. In case of static linked executables or in case of the dynamic linker itself, PROT_BTI protection is done by the operating system. On AArch64 glibc uses PT_GNU_PROPERTY instead of PT_NOTE to check the properties of a binary because PT_NOTE can be unreliable with old linkers (old linkers just append the notes of input objects together and add them to the output without checking them for consistency which means multiple incompatible GNU property notes can be present in PT_NOTE). BTI property is handled in the loader even if glibc is not built with BTI support, so in theory user code can be BTI protected independently of glibc. In practice though user binaries are not marked with the BTI property if glibc has no support because the static linked libc objects (crt files, libc_nonshared.a) are unmarked. This patch relies on Linux userspace API that is not yet in a linux release but in v5.8-rc1 so scheduled to be in Linux 5.8.

* aarch64: fix swapcontext for BTISzabolcs Nagy2020-07-081-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | setcontext returns to the specified context via an indirect jump, so there should be a BTI j. In case of getcontext (and all other returns_twice functions) the compiler adds BTI j at the call site, but swapcontext is a normal c call that is currently not handled specially by the compiler. So we change swapcontext such that the saved context returns to a local address that has BTI j and then swapcontext returns to the caller via a normal RET. For this we save the original return address in the slot for x1 of the context because x1 need not be preserved by swapcontext but it is restored when the context saved by swapcontext is resumed. The alternative fix (which is done on x86) would make swapcontext special in the compiler so BTI j is emitted at call sites, on x86 there is an indirect_return attribute for this, on AArch64 we would have to use returns_twice. It was decided against because such fix may need user code updates: the attribute has to be added when swapcontext is called via a function pointer and it breaks always_inline functions with swapcontext.

* 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 Desnoyers2020-07-062-0/+44
| | | | | | | | | | | | | | | | | | | 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]").

The scenario 10 from [2] might also occur in this configuration and INLINE_VSYSCALL will try to use the vDSO symbol and HAVE_CLOCK_GETTIME64_VSYSCALL does not set HAVE_VSYSCALL prior its usage. Also, there is no easy way to just enable the code to use one vDSO symbol since the macro INLINE_VSYSCALL is redefined if HAVE_VSYSCALL is set. Instead of adding more pre-processor handling and making the code even more convoluted, this patch removes the requirement of defining HAVE_VSYSCALL before including sysdep-vdso.h to enable vDSO usage. The INLINE_VSYSCALL is now expected to be issued inside a HAVE_*_VSYSCALL check, since it will try to use the internal vDSO pointers.

* Linux: Add tables with system call numbersFlorian Weimer2020-01-021-0/+291
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* nptl: Move nanosleep implementation to libcAdhemerval Zanella2019-11-061-2/+0
| | | | | | | | | Checked on x86_64-linux-gnu and powerpc64le-linux-gnu. I also checked the libpthread.so .gnu.version_d entries for every ABI affected and all of them contains the required versions (including for architectures which exports __nanosleep with a different version).

* nptl: Add pthread_clockjoin_npMike Crowe2019-11-011-0/+1
| | | | | | | | | | | Introduce pthread_clockjoin_np as a version of pthread_timedjoin_np that accepts a clockid_t parameter to indicate which clock the timeout should be measured against. This mirrors the recently-added POSIX-proposed "clock" wait functions. Checked on x86_64-linux-gnu. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* Make second argument of gettimeofday as 'void *'Zack Weinberg2019-10-301-2/+2
| | | | | | | | | | | | | Also make the public prototype of gettimeofday declare its second argument with type "void *" unconditionally, consistent with POSIX. It is also consistent with POSIX. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.
