* seccomp: allow defining separate filters for 32-bit archLibravatar Topi Miettinen2020-03-28
| | | | | | | | | | | | | | | | | | | | | System calls (names and numbers) are not exactly the same for 32 bit and 64 bit architectures. Let's allow defining separate filters for 32-bit arch using seccomp.32, seccomp.32.drop, seccomp.32.keep. This is useful for mixed 64/32 bit application environments like Steam and Wine. Implement protocol and mdwx filtering also for 32 bit arch. It's still better to block secondary archs completely if not needed. Lists of supported system calls are also updated. Warn if preload libraries would be needed due to trace, tracelog or postexecseccomp (seccomp.drop=execve etc), because a 32-bit dynamic linker does not understand the 64 bit preload libraries. Closes #3267. Signed-off-by: Topi Miettinen <toiwoton@gmail.com>
