2022-03-08bits/syscall.h: add landlock syscalls from linux v5.13Szabolcs Nagy-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.
2022-03-08bits/syscall.h: add mount_setattr from linux v5.12Szabolcs Nagy-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()

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.
2021-06-05riscv: rename __NR_fstatat __NR_newfstatatKhem Raj-1/+1
on riscv64 this syscall is called __NR_newfstatat this helps the name match kernel UAPI for external programs
2021-02-15bits/syscall.h: add process_madvise from linux v5.10Szabolcs Nagy-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

2020-09-09add pidfd_getfd and openat2 syscall numbers from linux v5.6Szabolcs Nagy-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
2019-12-30add clone3 syscall number from linux v5.3Szabolcs Nagy-0/+1

2019-09-11add new syscall numbers from linux v5.2Szabolcs Nagy-0/+7
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]
2019-08-03update riscv64 syscall numbers to linux v5.1Rich Felker-0/+8
commit f3f96f2daa4d00f0e38489fb465cd0244b531abe added these for the rest of the archs, but the patch it corresponded to missed riscv64 since riscv64 was not yet upstream at the time. this caused commit dfc81828f7ab41da08f744c44117a1bb20a05749 to break riscv64 build, due to a wrong assumption that SYS_statx was unconditionally defined.

I have tried to ensure that everyone with substantial contributions has been credited above; if any omissions are found they will be noted later in an update to the authors/contributors list in the COPYRIGHT file. The version committed here comes from the riscv/riscv-musl repo's commit 3fe7e2c75df78eef42dcdc352a55757729f451e2, with minor changes by me for issues found during final review: - a_ll/a_sc atomics are removed (according to the ISA spec, lr/sc are not safe to use in separate inline asm fragments) - a_cas[_p] is fixed to be a memory barrier - the call from the _start assembly into the C part of crt1/ldso is changed to allow for the possibility that the linker does not place them nearby each other. - DTP_OFFSET is defined correctly so that local-dynamic TLS works - reloc.h LDSO_ARCH logic is simplified and made explicit. - unused, non-functional crti/n asm files are removed. - an empty .sdata section is added to crt1 so that the __global_pointer reference is resolvable. - indentation style errors in some asm files are fixed.
