* arch: require arch-syscall-dump from arch-syscall-validateKir Kolyshkin2022-09-211-4/+5
| | | | | | | | | | | | | | | | | The arch-syscall-dump is almost always used from arch-syscall-validate (the only exception I found is when -c and -l are given), so it makes sense to check that it's available beforehand. Without this patch, when arch-syscall-dump is not present, the script produces lots of output with a few errors about the missing ./arch-syscall-dump hidden in the middle of it. To keep things simple, we require arch-syscall-dump even when it is not going to be used.

* arch: basic infrastructure for tracking per-syscall/ABI kernel versionsPaul Moore2022-05-091-29/+56
| | | | | | | | | | | | This commit adds basic support for tracking what kernel introduced a syscall for a given arch/ABI. It does not provide any of that kernel version information, leaving only a SCMP_KV_UNDEF placeholder, nor does it attempt to do anything meaningful with this new source of information; this patch simply establishes a new syscalls.csv format so that we can start properly recording the kernel versions.

* arch: Add SuperH 32-bit supportJohn Paul Adrian Glaubitz2021-03-081-1/+34
| | | | | | | | | | Initial support for seccomp for SuperH in Linux was added in 2.6.27-rc2, support for SECCOMP_FILTER was added for Linux 5.9. This adds support for SuperH in libseccomp, both for little-endian and big-endian mode.

* arch: use gperf to generate a perfact hash to lookup syscall namesGiuseppe Scrivano2020-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch significantly improves the performance of seccomp_syscall_resolve_name since it replaces the expensive strcmp for each syscall in the database, with a lookup table. The complexity for syscall_resolve_num is not changed and it uses the linear search, that is anyway less expensive than seccomp_syscall_resolve_name as it uses an index for comparison instead of doing a string comparison. On my machine, calling 1000 seccomp_syscall_resolve_name_arch and seccomp_syscall_resolve_num_arch over the entire syscalls DB passed from ~0.45 sec to ~0.06s. PM: After talking with Giuseppe I made a number of additional changes, some substantial, the highlights include: * various style tweaks * .gitignore fixes * fixed subject line, tweaked the description * dropped the arch-syscall-validate changes as they were masking other problems * extracted the syscalls.csv and file deletions to other patches to keep this one more focused * fixed the x86, x32, arm, all the MIPS ABIs, s390, and s390x ABIs as the syscall offsets were not properly incorporated into this change * cleaned up the ABI specific headers * cleaned up generate_syscalls_perf.sh and renamed to arch-gperf-generate * fixed problems with automake's file packaging Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com> Reviewed-by: Tom Hromatka <tom.hromatka@oracle.com> [PM: see notes in the "PM" section above] Signed-off-by: Paul Moore <paul@paul-moore.com>
