* arch,tools: change macros used to detect LoongArch64 to __loongarch_lp64WANG Xuerui2023-03-311-1/+1
| | | | | | | | | | | | According to the LoongArch Toolchain Conventions [1], `__loongarch64` is already deprecated for a while. What we care about here is the ABI data model, so change the `__loongarch64` to `__loongarch_lp64` instead.

| | | | | | | | | | 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.

* api: stop defining __NR_x values for syscalls that don't existPaul Moore2019-10-011-0/+1
| | | | | | | | | | | | | | | | | | Historically libseccomp has created a __NR_x definition for every syscall it supports, even those that aren't valid for a given ABI. While this seemed like a good idea at the time, it turned out to have some unwanted and nasty side effects. This patch finally corrects this problem. The basic approach is quite simple: move the SCMP_SYS() macro to use __SNR_x values instead of __NR_x values. The unfortunate side effect of this change is that instead of just worrying about #defines for the __PNR_x values we now have to have a __SNR_x define for *every* syscall. The good news is that after this patch that should only be a few new syscalls every year - a very manageable task.

* arch: Add parisc architecture supportHelge Deller2016-05-253-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (v4) adds support for the parisc and parisc64 architectures to libseccomp. I didn't split up the patch, because it's pretty trivial. Those parisc-specific files gets added: src/arch-parisc-syscalls.c src/arch-parisc.c src/arch-parisc.h src/arch-parisc64.c All other changes are trivial because they simply add parisc-specific case statements in variouse switch statements. I did ran a "make check" on x86-64 and parisc and all testcases succeeded. All live testcases succeed as well when running "./regression -T live". The patch applies cleanly to current libseccomp git head. Changes between v4 and v3 of this patch: - Added parisc arch to arch-syscall-check.c and fixup syscall table as needed - Fixed copyright notices in parisc files as suggested by Mike Frysinger Changes between v3 and v2 of this patch: - Stripped out patch which reports if a check was skipped because valgrind isn't installed. - Added tuxcall pseudo syscall for 19-sim-missing_syscalls testcase - Added sysmips pseudo syscall for 29-sim-pseudo_syscall testcase Changes between v2 and v1 of this patch: - Enabled seccomp mode 2 regression tests on parisc. Kernel support for hppa was added in kernel 4.6-rc1 and backported into the kernel v4.5.2 stable series.
