2020-11-11hurd: keep only required PLTs in ld.soSamuel Thibault
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.
2020-11-11hurd: Add missing startup callsSamuel Thibault
DL_SYSDEP_INIT and DL_PLATFORM_INIT were not getting called, leading to missing x86 platform tuning, now mandatory with 0f09154c6400 ("x86: Initialize CPU info via IFUNC relocation [BZ 26203]")

2020-10-09linux: Move xmknod{at} to compat symbolsAdhemerval Zanella
It also decouple mknod{at} from xmknod{at}. The riscv32 ABI was added on 2.33, so it is safe to remove the old __xmknot{at} symbols and just provide the newer mknod{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>
2020-10-09Remove mknod wrapper functions, move them to symbolsAdhemerval Zanella
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.

2020-10-09Remove stat wrapper functions, move them to exported symbolsAdhemerval Zanella
This patch removes the stat, stat64, lstat, lstat64, fstat, fstat64, fstatat, and fstatat64 static wrapper and add the symbol 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 a arch-specific xstatver.h file. The internal defines that redirects internals {f}stat{at} to their {f}xstat{at} counterparts are removed for Linux (!NO_RTLD_HIDDEN). Hurd still requires them since {f}stat{at} pulls extra objects that makes the loader build fail otherwise (I haven't dig into why exactly). Checked with a build for all affected ABIs.

It replaces the internal usage of __{f,l}xstat{at}{64} with the __{f,l}stat{at}{64}.

2020-08-05hurd: Rework sbrkSamuel Thibault
Making the brk start exactly at the end of the main application binary was requiring to get it through the _end symbol, which does not work any more with recent toolchains, and actually produces in libc.so a confusing external _end symbol that produces odd results, see https://sourceware.org/bugzilla/show_bug.cgi?id=23499 Trying to do so is quite outdated anyway with the tendency for address randomization. Using _end was also allowing to include the main binary data within the RLIMIT_DATA, but this also seems outdated with dynamic library loading, and nowadays' memory consumption via malloc and mmap rather than statically-allocated data. This adds a BRK_START macro in <vm_param.h> that just tells where we want to start the brk, and thus removes the _end symbol. * sysdeps/mach/hurd/i386/vm_param.h: New file. * sysdeps/mach/hurd/brk.c: Use BRK_START as brk start instead of _end. Also ignore __data_start. * hurd/Versions: Remove _end symbol. * sysdeps/mach/hurd/i386/libc.abilist: Remove _end symbol.

2020-07-08Remove --enable-obsolete-nsl configure flagPetr Vorel
this means that *always* libnsl is only built as shared library for backward compatibility and the NSS modules libnss_nis and libnss_nisplus are not built at all, libnsl's headers aren't installed. This compatibility is kept only for architectures and ABIs that have been added in or before version 2.28. Replacement implementations based on TIRPC, which additionally support IPv6, are available from <https://github.com/thkukuk/>. This change does not affect libnss_compat which does not depended on libnsl since 2.27 and thus can be used without NIS. libnsl code depends on Sun RPC, e.g. on --enable-obsolete-rpc (installed libnsl headers use installed Sun RPC headers), which will be removed in the following commit.

The strerrorname_np returns error number name (e.g. "EINVAL" for EINVAL) while strerrordesc_np returns string describing error number (e.g "Invalid argument" for EINVAL). Different than strerror, strerrordesc_np does not attempt to translate the return description, both functions return NULL for an invalid error number. They should be used instead of sys_errlist and sys_nerr, both are thread and async-signal safe. These functions are GNU extensions.

Different than strsignal, sigdescr_np does not attempt to translate the return description and both functions return NULL for an invalid signal number.

The compat code is also refactored by removing the over enginered errlist-compat.c generation from manual entried and extra comment token in linker script file. It disantangle the code generation from manual and simplify both Linux and Hurd compat code. The definitions from errlist.c are moved to errlist.h and a new test is added to avoid a new errno entry without an associated one in manual. Checked on x86_64-linux-gnu and i686-linux-gnu.

It refactor how signals are defined by each architecture. 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. For Hurd the BSD signum is removed and moved to a new header (it is used currently only on Hurd). Checked on a build against all affected ABIs.

2020-07-06Add the __libc_single_threaded variableFlorian Weimer
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. Using __libc_early_init and its initial flag, implementation of this variable is very straightforward. 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>

2020-06-19New exp10f version without SVID compat wrapperAdhemerval Zanella
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.
