I made a small tweak to the last patch to add more details to the per-ARCH help text, and to drop the needless "depends on SECCOMP" (which "depends on SECCOMP_FILTER" was already present). I successfully build-tested on parisc, powerpc, riscv, s390, and sh. xtensa doesn't build using the existing Debian cross-compiler, and I can't make csky with clang work, but they look correct. *cross fingers* [1/8] csky: Enable seccomp architecture tracking https://git.kernel.org/kees/c/ee7ce951028f [2/8] parisc: Enable seccomp architecture tracking https://git.kernel.org/kees/c/7f049cc068a3 [3/8] powerpc: Enable seccomp architecture tracking https://git.kernel.org/kees/c/95f8ae2624a0 [4/8] riscv: Enable seccomp architecture tracking https://git.kernel.org/kees/c/8f9f0f44a37b [5/8] s390: Enable seccomp architecture tracking https://git.kernel.org/kees/c/5897106c6902 [6/8] sh: Enable seccomp architecture tracking https://git.kernel.org/kees/c/75186111c257 [7/8] xtensa: Enable seccomp architecture tracking https://git.kernel.org/kees/c/4f408bc643aa [8/8] seccomp/cache: Report cache data through /proc/pid/seccomp_cache https://git.kernel.org/kees/c/49a6968cc78f
From: YiFei Zhu <yifeifz2@illinois.edu> This patch series enables bitmap cache for the remaining arches with SECCOMP_FILTER, other than MIPS. I was unable to find any of the arches having subarch-specific NR_syscalls macros, so generic NR_syscalls is used. SH's syscall_get_arch seems to only have the 32-bit subarch implementation. I'm not sure if this is expected. This series has not been tested; I have not built all the cross compilers necessary to build test, let alone run the kernel or benchmark the performance, so help on making sure the bitmap cache works as expected (selftests/seccomp/{seccomp_benchmark,seccomp_bpf}) would be appreciated. The series applies on top of Kees's for-next/seccomp branch. v1 -> v2: * ppc, sh: s/__SECCOMP_ARCH_LE_BIT/__SECCOMP_ARCH_LE/ * ppc: add "le" suffix to arch name when the arch is little endian. * ppc: add explanation of why __LITTLE_ENDIAN__ is used to commit message.
