* Revert "linux: Move xmknod{at} to compat symbols"Adhemerval Zanella2020-12-021-2/+0
| | | | | | | | | | | | | This reverts commit 81b83ff61f95f30ad53d6075247af0ea61a0b16e to move __xmknod{at} back to default symbols. ABIs with default symbol version of 2.33 or newer (such as riscv32) continue to just provide the mknod* symbols. The idea is to not force static libraries built against old glibc to update against new glibcs (since they reference the the xmknod{at} symbols). Checked on x86_64-linux-gnu and i686-linux-gnu.
* Remove tls.h inclusion from internal errno.hAdhemerval Zanella2020-11-131-0/+1
| | | | | | | | | | | | The tls.h inclusion is not really required and limits possible definition on more arch specific headers. This is a cleanup to allow inline functions on sysdep.h, more specifically on i386 and ia64 which requires to access some tls definitions its own. No semantic changes expected, checked with a build against all affected ABIs.
* linux: Move xmknod{at} to compat symbolsAdhemerval Zanella2020-10-091-17/+6
| | | | | | | | | | | 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>

In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg. This patch adds INLINE_SYSCALL_RETURN and INLINE_SYSCALL_ERROR_RETURN so that i386 can optimize setting errno by branching to the internal __syscall_error without PLT. INLINE_SYSCALL_ERROR_RETURN is designed to take the negative error number returned from the majority of Linux kernels for which negating is a no-op with INTERNAL_SYSCALL_ERRNO.

* Remove __ASSUME_ATFCTS conditionals in sysdeps/unix/sysv/linux/.Joseph Myers2014-06-201-46/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up for __ASSUME_ATFCTS now always being true for the supported Linux kernel versions by removing conditional code in sysdeps/unix/sysv/linux. Several fchownat.c files that were only present because of differences in the fallback syscalls used (depending on the architecture-specific names of chown-related syscalls for 32-bit uids) are removed. Files that looks like they could be replaced by syscalls.list entries have the standard "Consider moving to syscalls.list." comment (see bug 14138) added. Conditionals on the relevant __NR_* syscall numbers being defined are also removed, since my analysis indicated that the relevant syscalls are always defined for all relevant kernel versions using any affected file. Much of the removed fallback code had unbounded stack allocations, so this reduces the number of cases to consider for anyone reviewing uses of alloca and VLAs in glibc. There remain tests of __ASSUME_ATFCTS in io/openat.c (to determine whether to define __have_atfcts) and sysdeps/posix/getcwd.c (which also uses __have_atfcts); thus, the definition of __ASSUME_ATFCTS remains in kernel-features.h. The logical condition relevant there is whether openat64_not_cancel_3 is known to work. Hurd doesn't use this version of getcwd at all, so the conditionals in getcwd.c are always true in glibc. However, this code is also used in gnulib. So the best way to deal with the conditionals there may be for gnulib people to deal with merging all relevant changes in both directions between the glibc and gnulib versions of this file, at the end of which the openat conditionals should be in whatever form is best for gnulib, and hardcoded in the _LIBC case to having openat supported. Tested by comparing before-and-after disassembly of installed (stripped) shared libraries, on x86_64 and x86. On x86 the patch made no change to the disassembly; on x86_64, the only changes were in readlinkat, where formerly the return value from the readlinkat syscall was stored in an int variable before being converted to ssize_t for the return, and now the return value is returned directly without truncation to int. I think it's clearly correct not to truncate the return value (although I also think the truncation would not have been a user-visible bug because the kernel would never have returned a value it could have affected). * include/fcntl.h (__atfct_seterrno): Remove prototype.
