2023-11-10prlimit: add name redirection and fix incorrect parameters to syscallPavel Kozlov
The tst-rlimit/tst-rlimit64 tests pointed to several issueses in prlimit() function for 32-bit CPUs. This patch adds name redirection to prlimit64 in prlimit declaration to provide correct support for 64-bit offset (_FILE_OFFSET_BITS=64) on 32-bit CPUs and fixes improper field assignment and incorrect syscall paramerets in the prlimit() function. Fixes: 8c2f6218 ("setrlimit/getrlimit: fix prlimit64 syscall use for 32-bit CPUs") Signed-off-by: Pavel Kozlov <pavel.kozlov@synopsys.com>
2023-10-27setrlimit/getrlimit: fix prlimit64 syscall use for 32-bit CPUsPavel Kozlov
Commit 95e38b37 ("add support for systems without legacy setrlimit/getrlimit syscalls") has added use of the prlimit64 syscall in getrlimit and setrlimit functions. This change causes memory corruption on getrlimit call for 32-bit CPUs like ARC, as ARC doesn't have ugetrlimit syscall and uses prlimit64. Also, setrlimit has been broken by prlimit64 call on 32-bit CPUs like, i386, ARM, ARC. For the prlimit64 syscall the kernel expects an rlimit struct with 64-bit fields, but on 32-bit CPUs without _FILE_OFFSET_BITS=64 the struct rlimit has 32-bit fields. Add safe implementations of getrlimit, setrlimit, prlimit for 32-bit CPUs with a local struct rlimit64 variable for use in the prlimit64 syscall. For 64-bit CPUs and configurations with _FILE_OFFSET_BITS=64 use getrlimit, setrlimit, prlimit as aliases to getrlimit64, setrlimit64 and prlimit64. Add a new function prlimit64. Tested on aarch64, arm, i386, arc. Fixes: 95e38b37 ("add support for systems without legacy setrlimit/getrlimit syscalls") Signed-off-by: Pavel Kozlov <pavel.kozlov@synopsys.com>

2019-05-13preadv/pwritev: fix offset argument typeMax Filippov
preadv/pwritev don't provide separate version for 64-bit wide off_t, and default to 32-bit wide off_t, which results in a mismatch between declaration and definition for user programs built with -D_FILE_OFFSET_BITS=64. Make offset argument of both functions __off64_t. This fixes test misc/tst-preadvwritev on xtensa. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2017-10-01recvmmsg/sendmmsg: add recvmmsg sendmmsg support.Guo Ren
The recvmmsg and sendmmsg is very important for UDP stream application. If we only use recvmsg for UDP stream, it will only copy one mtu size of data in a syscall. And recvmmsg copy as many as you want in a syscall. So recvmmsg is more efficient,and some applications will depends on the recvmmsg and sendmmsg, eg: UDP media stream player.

2017-04-22sys/stat.h: fix missing struct timespec definitionDamien Riegel
This is a second attempt to fix a compilation failure involving a missing struct timespec definition in some situation. Previous attempt was following commit but it had undesirable side effects and was reverted: 657c4a9d6c fcntl.h: fix a missing `struct timespec` definition A similar issue was identified and reported in glibc [1], and the fix was to include the timespec definition if __USE_XOPEN2K8 was defined. To minimize the possible impact of this new fix, it was decided to not replace __USE_ATFILE by __USE_XOPEN2K8 as glibc did, but to add an additional OR condition on __USE_XOPEN2K8.

2016-06-15sysconf: Support _SC_(AV)?PHYS_PAGES.Nicolas Cavallari
Do it by following the trail of the existing commented code, which implemented it by calling get_phys_pages() and get_avphys_pages(). This patch implements these two functions, which are also glibc extensions. Some program/libraries (e.g. libuv) assumes that sysconf(_SC_PHYS_PAGES) works on linux and never check for -1, thus they report an insane amount of memory.

This drops __signed, __volatile, and __const. Only the latter was used in the code base, and for uClibc, not consistently. Much of the code used plain "const" which meant "__const" was useless.
