linux-toradex.git/arch/parisc/include/asm/syscall.h, branch v4.10 Linux kernel for Apalis and Colibri modules parisc: Add syscall tracepoint support 2016-05-22T19:38:47+00:00 Helge Deller deller@gmx.de 2016-04-13T20:44:54+00:00 fc79168a7c75423047d60a033dc4844955ccae0b This patch adds support for the TIF_SYSCALL_TRACEPOINT on the parisc architecture. Basically, it calls the appropriate tracepoints on syscall entry and exit. Signed-off-by: Helge Deller <deller@gmx.de>

parisc: Fix and enable seccomp filter support 2016-03-31T10:28:38+00:00 Helge Deller deller@gmx.de 2016-03-30T12:14:31+00:00 910cd32e552ea09caa89cdbe328e468979b030dd The seccomp filter support requires careful handling of task registers. This includes reloading of the return value (%r28) and proper syscall exit if secure_computing() returned -1. Additionally we need to sign-extend the syscall number from signed 32bit to signed 64bit in do_syscall_trace_enter() since the ptrace interface only allows storing 32bit values in compat mode.

ARCH: AUDIT: implement syscall_get_arch for all arches 2014-09-23T20:20:10+00:00 Eric Paris eparis@redhat.com 2014-03-11T17:50:46+00:00 ce5d112827e5c2e9864323d0efd7ec2a62c6dce0 For all arches which support audit implement syscall_get_arch() They are all pretty easy and straight forward, stolen from how the call to audit_syscall_entry() determines the arch.
