Fix the RLIM_INFINITY and RLIM64_INFINITY constants on alpha to match
the kernel one and all other architectures. Change the getrlimit,
getrlimit64, setrlimit, setrlimit64 into old compat symbols, and provide
the Linux generic functions as GLIBC_2_27 version.
Changelog:
* sysdeps/unix/sysv/linux/getrlimit64.c [USE_VERSIONED_RLIMIT]: Do not
define getrlimit and getrlimit64 as weak aliases of __getrlimit64.
Define __GI_getrlimit64 as weak alias of __getrlimit64.
[__RLIM_T_MATCHES_RLIM64_T]: Do not redefine SHLIB_COMPAT, use #elif
instead.
* sysdeps/unix/sysv/linux/setrlimit64.c [USE_VERSIONED_RLIMIT]: Do not
define setrlimit and setrlimit64 as weak aliases of __setrlimit64.
* sysdeps/unix/sysv/linux/alpha/bits/resource.h (RLIM_INFINITY,
RLIM64_INFINITY): Fix values to match the kernel ones.
* sysdeps/unix/sysv/linux/alpha/getrlimit64.c: Define
USE_VERSIONED_RLIMIT. Rename __getrlimit64 into __old_getrlimit64 and
provide it as getrlimit@@GLIBC_2_0 and getrlimit64@@GLIBC_2_1. Add a
__getrlimit64 function and provide it as getrlimit@@GLIBC_2_27 and
getrlimit64@@GLIBC_2_27.
* sysdeps/unix/sysv/linux/alpha/setrlimit64.c: Ditto with setrlimit
and setrlimit64.
* sysdeps/unix/sysv/linux/alpha/libc.abilist (GLIBC_2.27): Add
getrlimit, setrlimit, getrlimit64 and setrlimit64.
* sysdeps/unix/sysv/linux/alpha/Versions (libc): Add getrlimit,
setrlimit, getrlimit64 and setrlimit64.

This patch makes sysdeps/unix/sysv/linux code assume the prlimit64
syscall is always available, given the minimum of a 3.2 kernel.
__ASSUME_PRLIMIT64, which in fact was no longer used, is removed.
Code conditional on __NR_prlimit64 being defined is made
unconditional. Fallback code for the case where prlimit64 produces an
ENOSYS error is removed, substantially simplifying some functions.
Tested for x86_64 and x86.
* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_PRLIMIT64):
Remove macro.
* sysdeps/unix/sysv/linux/getrlimit64.c (__getrlimit64): Assume
prlimit64 is always available and does not give an ENOSYS error.
* sysdeps/unix/sysv/linux/prlimit.c [__NR_prlimit64]: Make code
unconditional.
[!__NR_prlimit64]: Remove conditional code.
* sysdeps/unix/sysv/linux/setrlimit.c (__setrlimit): Assume
prlimit64 is always available and does not give an ENOSYS error.

This patch consolidates all Linux setrlimit and getrlimit on the default
sysdeps/unix/sysv/linux/{set,get}rlimit{64}.c. It contains two exceptions:
1. mips32 and mips64n32 which requires a versioned symbol for GLIBC 2.19
and higher due a broken RLIM64_INFINITY constant.
2. sparc32 does not define a compat symbol for getrlimit64 for old 2GB
limit. I am not sure if it is required, but a RLIM_INFINITY fix [1]
change its definition without adding a compat symbol. This patch does
not aim to address this possible issue, it follow current symbol
export.
The default implementation uses prlimit64 for 64 bit rlim_t ({set,get}rlimit64)
and if it fails with ENOSYS it fall back to {get,set}rlimit syscall. This
code path is only used on kernel older than 2.6.36 (basically now only x86)
and I avoid to user __ASSUME_PRLIMTI64 to simplify the implementation. Once
x86 moves to be on par with other architectures regarding minimum kernel
supported we can get rid of using old syscalls and default path.
A new type size define is added, __RLIM_T_MATCHES_RLIM64_T, where is set as
default for 64 bits ports. This allows the default implementation to avoid
{get,set}rlimit building and alias {get,set}rlimit64 to {get,set}rlimit.
Checked on x86_64, i386, armhf, aarch64, and powerpc64le. I also did a
sanity build plus check-abi on all other supported architectures.

This mostly automatically-generated patch converts 231 sysdeps
function definitions in glibc from old-style K&R to prototype-style.
For __aio_sigqueue and __gai_sigqueue I had to add internal_function
to the definitions as noted by Florian in
<https://sourceware.org/ml/libc-alpha/2015-10/msg00595.html> to keep
the functions compiling on x86 after conversion to prototype
definitions. Otherwise, the patch is automatically generated with all
the same exclusions and caveats as in
<https://sourceware.org/ml/libc-alpha/2015-10/msg00594.html> except
that it's a patch for sysdeps files.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch). Also tested for arm,
mips64 and powerpc32 that installed stripped shared libraries are
unchanged by the patch.

This reverts commit 0c5b8b5941e036dcaac69cecee9f01fdf9218e6e.
|

For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno. 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.
With i386 INLINE_SYSCALL_RETURN, INLINE_SYSCALL_ERROR_RETURN and
i386 syscall inlining optimization for GCC 5, for
sysdeps/unix/sysv/linux/fchmodat.c with -O2 -march=i686
-mtune=generic, GCC 5.2 now generates:
