* Assume prlimit64 is available.Joseph Myers2017-05-091-6/+1
| | | | | | | | | | | | | | | | | | | | | | | 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. * sysdeps/unix/sysv/linux/setrlimit64.c (__setrlimit64): Likewise.

* Consolidate Linux setrlimit and getrlimit implementationAdhemerval Zanella2016-11-171-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
