Dmitry V. Levin	745c53410f	Add SECCOMP_RET_KILL_PROCESS decoding support ... * bpf_seccomp_filter.c [!SECCOMP_RET_ACTION]: Remove. [!SECCOMP_RET_ACTION_FULL] (SECCOMP_RET_ACTION_FULL): Define. (print_seccomp_filter_k): Use SECCOMP_RET_ACTION_FULL instead of SECCOMP_RET_ACTION. * xlat/seccomp_ret_action.in: Add SECCOMP_RET_KILL_PROCESS introduced by linux kernel commit v4.14-rc2~15^2~3.	2017-11-01 02:05:41 +00:00
Dmitry V. Levin	899220d28d	Generalize seccomp filter parser ... Linux socket filter uses almost the same classic BPF as seccomp filter, The only difference noticeable from strace PoV is the meaning of generic multiuse field. Transform the parser of seccomp filters to a more generic parser of classic BPF, parametrized with a method of parsing the generic multiuse field in BPF_STMT. * bpf_filter.c: New file. * bpf_filter.h: Likewise. * bpf_fprog.h: Likewise. * bpf_seccomp_filter.c: Likewise. * fetch_bpf_fprog.c: Likewise. * fetch_seccomp_fprog.c: Remove. * seccomp_fprog.h: Likewise. * Makefile.am (strace_SOURCES): Add bpf_filter.c, bpf_filter.h, bpf_fprog.h, bpf_seccomp_filter.c, and fetch_bpf_fprog.c. Remove fetch_seccomp_fprog.c and seccomp_fprog.h. * seccomp.c: Do not include linux/filter.h and xlat header files. Do not define SECCOMP_RET_ACTION. (bpf_filter, decode_bpf_code, decode_bpf_stmt, decode_bpf_jump, print_bpf_filter, print_seccomp_fprog, print_seccomp_filter): Remove. * defs.h (print_seccomp_filter): Rename to decode_seccomp_fprog. (SYS_FUNC(seccomp)): Replace print_seccomp_filter with decode_seccomp_fprog. * prctl.c (SYS_FUNC(prctl)): Likewise.	2017-07-08 01:49:00 +00:00
