2023-11-17rlimit: fix 64-bit RLIM64_INFINITY macroPavel Kozlov
Linux kernel returns -1ULL as RLIM64_INFINITY for all cpus. Fix RLIM64_INFINTIY and 64-bit variant of RLIM_INFINITY macro for sparc, mips, alpha, as for these CPUs the library uses different value than what the kernel sets and it can cause incorrect RLIM64_INFINTY check. Because alpha is a 64-bit arch, fix the RLIM_INFINITY macro twice (the value should be the same with and without __USE_FILE_OFFSET64 definition) to match the prlimit64 syscall in the kernel. Previous implementation of setrlimit/getrlimit functions didn't use prlimit64 syscall and didn't receive RLIM64_INFINTIY from the kernel, RLIM64_INFINTY macro was used by the library itself to mimic the 64-bit rlimit in the getrlimit64/setrlimit64 functions, that allowed to have RLIM64_INFINTIY different from what the kernel sets. New implementation of setrlimit/getrlimit uses prlimit64 and checks for RLIM64_INFINITY value and must have equal RLIM64_INFINITY definition with what the kernel uses. This issue is indicated by the tst-rlim/tst-rlim64 tests on sparc/mips32/alpha, tests return 23 (UNSUPPORTED) because of incorrect RLIM_INFINTY check for available rlimit type. This patch will require rebuild of sparc/mips32/alpha binaries that explicitly use RLIM64_INFINTY or 64-bit variant of RLIM_INFINITY (if binary for 32-bit CPU was built with _FILE_OFFSET_BITS=64) to update the macro value.

2022-05-20define RLIMIT_RTTIME, bump RLIMIT_NLIMITSRomain Naour
This macro exists since Linux 2.6.25 [1] and is defined in glibc since 2.14 [2] for sparc and most supported architectures. RLIMIT_RTTIME has been added later for mips [3] and alpha [4]. For example, RLIMIT_RTTIME is needed to build qemu 7.0.0 with Linux user-land emulation support [5].

2021-04-09open: Add support for O_TMPFILENicolas Cavallari
Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY) to make it fail on old kernels. Copying definitions from glibc for O_TMPFILE is not enough to support O_TMPFILE; The open() wrapper also need to pass the mode when the flag contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed but yield unexpected results. openat() is curiously not affected since it passes the mode unconditionally..

2020-07-02Rename __unused struct members to include a namespaceEd Wildgoose
Rename various spare fields in structs to include a namespace This should avoid accidental clashes with uses of the __unused symbol in upstream projects. eg currently it causes a compile error in dhcpcd 8.x due to their re-use of the __unused symbol as a macro This follows the style of glibc which does something equivalent
2020-05-17mips: Do not include hi and lo in __SYSCALL_CLOBBERS for R6Romain Naour
From [1] "GCC 10 (PR 91233) won't silently allow registers that are not architecturally available to be present in the clobber list anymore, resulting in build failure for mips*r6 targets in form of: ... .../sysdep.h:146:2: error: the register ‘lo’ cannot be clobbered in ‘asm’ for the current target 146 | __asm__ volatile ( \ | ^~~~~~~ This is because base R6 ISA doesn't define hi and lo registers w/o DSP extension.

2018-11-23Defined INLINE_SYSCALL_NOERR_NCS in mips/bits/syscalls.hVolodymyr Boyko
On Linux/MIPS (O32 ABI) for system call we have two result registers - v0 and a3. v0 contains actual syscall result on success or error number on fail, a3 set to 0/1 for indicating syscall success/fail. (if a3 == 1, v0 contains errno). Now as we can see from definition of handle_sys (arch/mips/kernel/scall32-o32.S), handler treats returned by syscall function (let's call "original") values in range [-EMAXERRNO; 0[ as -errno, a3 is set to 1 and final returned (to userspace) value is (-original). INLINE_SYSCALL_NOERR_NCS defined in mips/bits/syscalls.h will handle this behaviour. Signed-off-by: Volodymyr Boyko <boyko.cxx@gmail.com>

2015-06-10siginfo: add signal info for seccomp related SIGSYSDaniel Golle
uClibc doesn't define signal info for the SIGSYS signal which is issued in case of hitting a syscall prohibited by seccomp. This is sad as it makes debugging seccomp filter policies impossible on some architectures (at least ARM and PowerPC, maybe also others) which do not coincidentally set si_value.sival_int as the syscall number.

This patch fixes the rest of the set-but-not-used warnings in the MIPS code by using attribute_unused and also fixes some conversion warnings by changing __arch_compare_and_exchange_xxx_[8|16]_int. Assigning __cmp (int type) to __prev (pointer type) generates a warning. Assigning zero to each separately avoids this warning without having to add a cast.

2014-02-02libc: mips: Fix setjmp/longjmp for MIPS64 N64 ABIWaldemar Brodkorb
When booting a Linux system with qemu-system-mips64 the execution of $(pwd) in the ash shell triggers a segmentation fault. Ash uses setjmp/longjmp for exception handling. After looking at the glibc implementation, I found some differences, with this patch tries to resolve. Now the system boots up fine and no segmentation faults occur. The global pointer should be restored and the types for the register values should be wide enough.

2013-04-01mips: only define SYSCALL_ALIGN_64BIT for O32 ABIsMike Frysinger
The 64bit register alignment issue only affects the O32 ABI, so wrap the define accordingly. We don't want this being used for N32 ABIs.

2013-04-01libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BITMike Frysinger
The reason truncate64 takes 4 args on some arches is that their ABI requires 64bit values to be aligned on register pair boundaries. Since this alignment affects more than just truncate64, rename the define to properly document its purpose. This also allows us to expand it to the other impacted syscalls (which will be done in a follow up commit). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
