git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs 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

To pick the changes from: 55db9c0e8534 ("net: remove compat_sys_{get,set}sockopt") 9b4feb630e8e ("arch: wire-up close_range()") That automagically add the 'close_range' syscall to tools such as 'perf trace'.

2020-07-19net: remove compat_sys_{get,set}sockoptChristoph Hellwig1-2/+2
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.

To get the change in: b7d624ab4312 ("asm-generic: unistd.h: fixup broken macro include.") That doesn't imply in any changes in the tools.

To get the changes in: 82b355d161c9 ("y2038: Remove newstat family from default syscall set") Which will make the syscall table used by 'perf trace' for arm64 to be updated from the changes in that patch.

2018-09-11tools headers uapi: Update tools's copy of asm-generic/unistd.hArnaldo Carvalho de Melo1-1/+3
To get the changes in: db7a2d1809a5 ("asm-generic: unistd.h: Wire up sys_rseq") That wires up the new 'rsec' system call, which will automagically support that syscall in the syscall table used by 'perf trace' on arm/arm64.

Will be used for generating the syscall id/string translation table. The arm64 unistd.h file simply #includes the asm-generic/unistd.h, so, since we will want to know whether either change, we grab both: arch/arm64/include/uapi/asm/unistd.h and include/uapi/asm-generic/unistd.h Signed-off-by: Kim Phillips <kim.phillips@arm.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com> Cc: Thomas Richter <tmricht@linux.vnet.ibm.com> Link: http://lkml.kernel.org/r/20180706163434.1b64ffbcc0284fb79982f53b@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
