* bits/syscall.h: add landlock syscalls from linux v5.13Szabolcs Nagy2022-03-081-0/+3
| | | | | | | | | | | | | | | | | see linux commit a49f4f81cb48925e8d7cbd9e59068f516e984144 arch: Wire up Landlock syscalls linuxcommit 17ae69aba89dbfa2139b7f8024b757ab3cc42f59 Merge tag 'landlock_v34' of ... jmorris/linux-security Landlock provides for unprivileged application sandboxing. The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic.
* bits/syscall.h: add mount_setattr from linux v5.12Szabolcs Nagy2022-03-081-0/+1
| | | | | | | | new syscall to change the properties of a mount or a mount tree using file descriptors which the new mount api is based on, see linux commit 2a1867219c7b27f928e2545782b86daaf9ad50bd fs: add mount_setattr()
* bits/syscall.h: add epoll_pwait2 from linux v5.11Szabolcs Nagy2022-03-081-0/+1
| | | | | | | | | | | | see linux commit b0a0c2615f6f199a656ed8549d7dce625d77aa77 epoll: wire up syscall epoll_pwait2 linux commit 58169a52ebc9a733aeb5bea857bc5daa71a301bb epoll: add syscall epoll_pwait2 epoll_wait with struct timespec timeout instead of int. no time32 variant.
* bits/syscall.h: add process_madvise from linux v5.10Szabolcs Nagy2021-02-151-0/+1
| | | | | | | | | mainly added to linux to allow a central process management service in android to give MADV_COLD|PAGEOUT hints for other processes, see linux commit ecb8ac8b1f146915aa6b96449b66dd48984caacc mm/madvise: introduce process_madvise() syscall: an external memory hinting API
* bits/syscall.h: add __NR_close_range from linux v5.9Szabolcs Nagy2020-11-291-0/+1
| | | | | | | | | | see linux commit 9b4feb630e8e9801603f3cab3a36369e3c1cf88d arch: wire-up close_range() linux commit 278a5fbaed89dacd04e9d052f4594ffd0e0585de open: add close_range()
* bits/syscall.h: add __NR_faccessat2 from linux v5.8Szabolcs Nagy2020-09-091-0/+1
| | | | | | | | the linux faccessat syscall lacks a flag argument that is necessary to implement the posix api, see linux commit c8ffd8bcdd28296a198f237cc595148a8d4adfbe vfs: add faccessat2 syscall
* add pidfd_getfd and openat2 syscall numbers from linux v5.6Szabolcs Nagy2020-09-091-0/+2
| | | | | | | | | | | | | | | | | | | also added clone3 on sh and m68k, on sh it's still missing (not yet wired up), but reserved so safe to add. see linux commit fddb5d430ad9fa91b49b1d34d0202ffe2fa0e179 open: introduce openat2(2) syscall linux commit 9a2cef09c801de54feecd912303ace5c27237f12 arch: wire up pidfd_getfd syscall linux commit 8649c322f75c96e7ced2fec201e123b2b073bf09 pid: Implement pidfd_getfd syscall linux commit e8bb2a2a1d51511e6b3f7e08125d52ec73c11139 m68k: Wire up clone3() syscall
* remove legacy time32 timer[fd] syscalls from public syscall.hRich Felker2020-02-051-4/+4
| | | | | | | this extends commit 5a105f19b5aae79dd302899e634b6b18b3dcd0d6, removing timer[fd]_settime and timer[fd]_gettime. the timerfd ones are likely to have been used in software that started using them before it could rely on libc exposing functions.
* remove further legacy time32 clock syscalls from public syscall.hRich Felker2020-02-051-4/+4
| | | | | this extends commit 5a105f19b5aae79dd302899e634b6b18b3dcd0d6, removing clock_settime, clock_getres, clock_nanosleep, and settimeofday.
* remove legacy clock_gettime and gettimeofday from public syscall.hRich Felker2020-01-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | some nontrivial number of applications have historically performed direct syscalls for these operations rather than using the public functions. such usage is invalid now that time_t is 64-bit and these syscalls no longer match the types they are used with, and it was already harmful before (by suppressing use of vdso). since syscall() has no type safety, incorrect usage of these syscalls can't be caught at compile-time. so, without manually inspecting or running additional tools to check sources, the risk of such errors slipping through is high. this patch renames the syscalls on 32-bit archs to clock_gettime32 and gettimeofday_time32, so that applications using the original names will fail to build without being fixed. note that there are a number of other syscalls that may also be unsafe to use directly after the time64 switchover, but (1) these are the main two that seem to be in widespread use, and (2) most of the others continue to have valid usage with a null timeval/timespec argument, as the argument is an optional timeout or similar.
* add clone3 syscall number from linux v5.3Szabolcs Nagy2019-12-301-0/+1
| | | | | | | | | | | | | | the syscall number is reserved on all targets, but it is not wired up on all targets, see linux commit 8f6ccf6159aed1f04c6d179f61f6fb2691261e84 Merge tag 'clone3-v5.3' of ... brauner/linux linux commit 8f3220a806545442f6f26195bc491520f5276e7c arch: wire-up clone3() syscall linux commit 7f192e3cd316ba58c88dfa26796cf77789dd9872 fork: add clone3

* add new syscall numbers from linux v5.2Szabolcs Nagy2019-09-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | new mount api syscalls were added, same numers on all targets, see linux commit a07b20004793d8926f78d63eb5980559f7813404 vfs: syscall: Add open_tree(2) to reference or clone a mount linux commit 2db154b3ea8e14b04fee23e3fdfd5e9d17fbc6ae vfs: syscall: Add move_mount(2) to move mounts around linux commit 24dcb3d90a1f67fe08c68a004af37df059d74005 vfs: syscall: Add fsopen() to prepare for superblock creation linux commit ecdab150fddb42fe6a739335257949220033b782 vfs: syscall: Add fsconfig() for configuring and managing a context linux commit 93766fbd2696c2c4453dd8e1070977e9cd4e6b6d vfs: syscall: Add fsmount() to create a mount for a superblock linux commit cf3cba4a429be43e5527a3f78859b1bfd9ebc5fb vfs: syscall: Add fspick() to select a superblock for reconfiguration linux commit 9c8ad7a2ff0bfe58f019ec0abc1fb965114dde7d uapi, x86: Fix the syscall numbering of the mount API syscalls [ver #2] linux commit d8076bdb56af5e5918376cd1573a6b0007fc1a89 uapi: Wire up the mount API syscalls on non-x86 arches [ver #2]
* add new syscall numbers from linux v5.1Szabolcs Nagy2019-07-011-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | syscall numbers are now synced up across targets (starting from 403 the numbers are the same on all targets other than an arch specific offset) IPC syscalls sem*, shm*, msg* got added where they were missing (except for semop: only semtimedop got added), the new semctl, shmctl, msgctl imply IPC_64, see linux commit 0d6040d4681735dfc47565de288525de405a5c99 arch: add split IPC system calls where needed new 64bit time_t syscall variants got added on 32bit targets, see linux commit 48166e6ea47d23984f0b481ca199250e1ce0730a y2038: add 64-bit time_t syscalls to all 32-bit architectures new async io syscalls got added, see linux commit 2b188cc1bb857a9d4701ae59aa7768b5124e262e Add io_uring IO interface linux commit edafccee56ff31678a091ddb7219aba9b28bc3cb io_uring: add support for pre-mapped user IO buffers a new syscall got added that uses the fd of /proc/<pid> as a stable handle for processes: allows sending signals without pid reuse issues, intended to eventually replace rt_sigqueueinfo, kill, tgkill and rt_tgsigqueueinfo, see linux commit 3eb39f47934f9d5a3027fe00d906a45fe3a15fad signal: add pidfd_send_signal() syscall on some targets (arm, m68k, s390x, sh) some previously missing syscall numbers got added as well.
* add io_pgetevents and rseq syscall numbers from linux v4.18Szabolcs Nagy2018-12-091-0/+2
| | | | | | | | io_pgetevents is new in linux commit 7a074e96dee62586c935c80cecd931431bfdd0be rseq is new in linux commit d7822b1e24f2df5df98c76f0e94a5416349ff759
* powerpc: add pkey syscall numbers from linux v4.16Szabolcs Nagy2018-06-191-0/+3
| | | | | | add pkey_mprotect, pkey_alloc, pkey_free syscall numbers, new in linux commits 3350eb2ea127978319ced883523d828046af4045 and 9499ec1b5e82321829e1c1510bcc37edc20b6f38
* add statx syscall numbers from linux v4.11Szabolcs Nagy2017-11-051-0/+1
| | | | | statx was added in linux commit a528d35e8bfcc521d7cb70aaf03e1bd296c8493f (there is no libc wrapper yet and microblaze and sh misses the number).
* add kexec_file_load syscall number on powerpc from linux v4.10Szabolcs Nagy2017-11-051-0/+1
| | | | added in linux commit 80f60e509a03ff9ff2bdbf9cd1e935c6360b8bd9
* make syscall.h consistent with linuxSzabolcs Nagy2017-09-061-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | most of the found naming differences don't matter to musl, because internally it unifies the syscall names that vary across targets, but for external code the names should match the kernel uapi. aarch64: __NR_fstatat is called __NR_newfstatat in linux. __NR_or1k_atomic got mistakenly copied from or1k. arm: __NR_arm_sync_file_range is an alias for __NR_sync_file_range2 __NR_fadvise64_64 is called __NR_arm_fadvise64_64 in linux, the old non-arm name is kept too, it should not cause issues. (powerpc has similar nonstandard fadvise and it uses the normal name.) i386: __NR_madvise1 was removed from linux in commit 303395ac3bf3e2cb488435537d416bc840438fcb 2011-11-11 microblaze: __NR_fadvise, __NR_fstatat, __NR_pread, __NR_pwrite had different name in linux. mips: __NR_fadvise, __NR_fstatat, __NR_pread, __NR_pwrite, __NR_select had different name in linux. mipsn32: __NR_fstatat is called __NR_newfstatat in linux. or1k: __NR__llseek is called __NR_llseek in linux. the old name is kept too because that's the name musl uses internally. powerpc: __NR_{get,set}res{gid,uid}32 was never present in powerpc linux. __NR_timerfd was briefly defined in linux but then got renamed.
* add preadv2 and pwritev2 syscall numbers for linux v4.6Szabolcs Nagy2016-06-091-0/+2
| | | | | | | | the syscalls take an additional flag argument, they were added in commit f17d8b35452cab31a70d224964cd583fb2845449 and a RWF_HIPRI priority hint flag was added to linux/fs.h in 97be7ebe53915af504fb491fb99f064c7cf3cb09. the syscall is not allocated for microblaze and sh yet.
