Firstly support is added for building the seccomp_bpf self test for MIPS. The initial results of these tests were: 32bit kernel O32 userspace before: 48 / 48 pass 64bit kernel O32 userspace before: 47 / 48 pass Failures: TRAP.Handler 64bit kernel N32 userspace before: 44 / 48 pass Failures: global.mode_strict_support, TRAP.handler, TRACE_syscall.syscall_redirected, TRACE_syscall.syscall_dropped 64bit kernel N64 userspace before: 46 / 48 pass Failures: TRACE_syscall.syscall_redirected, TRACE_syscall.syscall_dropped The subsequent patches fix issues that were causing the above tests to fail. With these fixes, the results are: 32bit kernel O32 userspace after: 48 / 48 64bit kernel O32 userspace after: 48 / 48 64bit kernel N32 userspace after: 48 / 48 64bit kernel N64 userspace after: 48 / 48 Thanks, Matt Changes in v2: - Tested on additional platforms - Replace __NR_syscall which isn't defined for N32 / N64 ABIs Matt Redfearn (6): selftests/seccomp: add MIPS self-test support MIPS: Support sending SIG_SYS to 32bit userspace from 64bit kernel MIPS: scall: Handle seccomp filters which redirect syscalls seccomp: Get compat syscalls from asm-generic header MIPS: seccomp: Support compat with both O32 and N32 secomp: Constify mode1 syscall whitelist arch/mips/include/asm/seccomp.h | 47 +++++++++++++++------------ arch/mips/kernel/scall32-o32.S | 11 +++---- arch/mips/kernel/scall64-64.S | 3 +- arch/mips/kernel/scall64-n32.S | 14 +++++--- arch/mips/kernel/scall64-o32.S | 14 +++++--- arch/mips/kernel/signal32.c | 6 ++++ include/asm-generic/seccomp.h | 14 ++++++++ kernel/seccomp.c | 13 ++------ tools/testing/selftests/seccomp/seccomp_bpf.c | 30 +++++++++++++++-- 9 files changed, 101 insertions(+), 51 deletions(-) -- 2.5.0
