tools headers: Update syscall.tbl files to support mount_setattr

2021-03-06T19:54:30Z

To pick the changes from: 9caccd41541a6f7d ("fs: introduce MOUNT_ATTR_IDMAP") This adds this new syscall to the tables used by tools such as 'perf trace', so that one can specify it by name and have it filtered, etc. Addressing these perf build warnings: Warning: Kernel ABI header at 'tools/perf/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl' diff -u tools/perf/arch/x86/entry/syscalls/syscall_64.tbl arch/x86/entry/syscalls/syscall_64.tbl Warning: Kernel ABI header at 'tools/perf/arch/powerpc/entry/syscalls/syscall.tbl' differs from latest version at 'arch/powerpc/kernel/syscalls/syscall.tbl' diff -u tools/perf/arch/powerpc/entry/syscalls/syscall.tbl arch/powerpc/kernel/syscalls/syscall.tbl Warning: Kernel ABI header at 'tools/perf/arch/s390/entry/syscalls/syscall.tbl' differs from latest version at 'arch/s390/kernel/syscalls/syscall.tbl' diff -u tools/perf/arch/s390/entry/syscalls/syscall.tbl arch/s390/kernel/syscalls/syscall.tbl Cc: Adrian Hunter Cc: Christian Brauner Cc: Ian Rogers Cc: Jiri Olsa Cc: Namhyung Kim Link: http://lore.kernel.org/lkml/YD6Wsxr9ByUbab/a@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf arch powerpc: Sync powerpc syscall.tbl with the kernel sources

2021-03-06T19:54:23Z

To get the changes in: fbcee2ebe8edbb6a ("powerpc/32: Always save non volatile GPRs at syscall entry") That shouldn't cause any change in tooling, just silences the following tools/perf/ build warning: Warning: Kernel ABI header at 'tools/perf/arch/powerpc/entry/syscalls/syscall.tbl' differs from latest version at 'arch/powerpc/kernel/syscalls/syscall.tbl' Cc: Christophe Leroy Cc: Michael Ellerman Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Update powerpc's syscall.tbl copy from the kernel sources

Merge branch 'compat.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2020-10-12T23:44:57Z

Pull compat mount cleanups from Al Viro: "The last remnants of mount(2) compat buried by Christoph. Buried into NFS, that is. Generally I'm less enthusiastic about "let's use in_compat_syscall() deep in call chain" kind of approach than Christoph seems to be, but in this case it's warranted - that had been an NFS-specific wart, hopefully not to be repeated in any other filesystems (read: any new filesystem introducing non-text mount options will get NAKed even if it doesn't mess the layout up). IOW, not worth trying to grow an infrastructure that would avoid that use of in_compat_syscall()..." * 'compat.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs: remove compat_sys_mount fs,nfs: lift compat nfs4 mount data handling into the nfs code nfs: simplify nfs4_parse_monolithic

all arch: remove system call sys_sysctl

2020-08-15T02:56:56Z

Since commit 61a47c1ad3a4dc ("sysctl: Remove the sysctl system call"), sys_sysctl is actually unavailable: any input can only return an error. We have been warning about people using the sysctl system call for years and believe there are no more users. Even if there are users of this interface if they have not complained or fixed their code by now they probably are not going to, so there is no point in warning them any longer. So completely remove sys_sysctl on all architectures.

net: remove compat_sys_{get,set}sockopt

2020-07-20T01:16:40Z

Now that the ->compat_{get,set}sockopt proto_ops methods are gone there is no good reason left to keep the compat syscalls separate. This fixes the odd use of unsigned int for the compat_setsockopt optlen and the missing sock_use_custom_sol_socket. It would also easily allow running the eBPF hooks for the compat syscalls, but such a large change in behavior does not belong into a consolidation patch like this one.
