* all: update the syscall validation code/scripts for January 2017Paul Moore2017-01-251-1/+1
| | | | | | | | A variety of updates to reflect changes in the Linux Kernel and the library itself with the goal of making sure the syscall checking scripts continue to work. Signed-off-by: Paul Moore <paul@paul-moore.com>
* all: update my email addressPaul Moore2016-02-111-1/+1
| | | | | | | Employer agnostic emails make things a lot easier in the long run so make sure the paul-moore.com address is used whenever it makes sense. Signed-off-by: Paul Moore <paul@paul-moore.com>
* arch: generate both multiplexed and direct socket syscall rulesPaul Moore2016-02-091-1/+1
| | | | | | | | | Linux 4.3 added direct-wired socket syscalls in addition to the multiplexed socket syscalls available via socketcall(). This patch causes libseccomp to generate filters for socket syscall methods on x86 systems. Signed-off-by: Paul Moore <paul@paul-moore.com>
* arch: enable more involved arch/ABI specific rule creationPaul Moore2016-02-091-1/+2
| | | | | | | Create the infrastructure for arch/ABI specific rule creation that allows us much more involved arch/ABI customization. Signed-off-by: Paul Moore <pmoore@redhat.com>
* arch: make use of function tables instead of switch statementsPaul Moore2016-02-091-3/+2
| | | | Signed-off-by: Paul Moore <pmoore@redhat.com>
* db: store the rules used to build the filterPaul Moore2016-02-091-1/+1
| | | | | | | This will be useful in future patches for rebuilding and manipulating the filter. Signed-off-by: Paul Moore <pmoore@redhat.com>
* all: block negative syscall numbers from the filterPaul Moore2015-08-271-1/+1
| | | | | | | | | | | We use negative syscalls numbers to indicate syscalls that aren't supported by a certain arch/ABI and unfortunately there were cases where these bogus syscall values were finding their way into the filter. This patch corrects this and adds a new test to check for this in the future. Reported-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Moore <pmoore@redhat.com>
* arch: perform a number of simplications in the arch codePaul Moore2014-08-271-4/+0
| | | | | | | | | I've been putting off simplifing the arch specific code until we had enough ABIs to know what simplifications made sense. Well, our supported ABI list is not quite reasonable so go ahead and clean things up a bit. Signed-off-by: Paul Moore <pmoore@redhat.com>
* tests: create a simple program to test the internal syscall tablesPaul Moore2014-05-221-0/+2
| | | | | | | | | | | | | This patch adds a dead simple, and a bit hack-ish, little program that checks the internal syscall tables for consistency across the different supported architectures. We also tie this test into the autotools test infrastructure. This should be of particular importance when adding or updating architectures. This patch also fixed some automake/libtool problems which were causing us to double-build some objects under src/. Signed-off-by: Paul Moore <pmoore@redhat.com>
* all: resolve issues caused by big endian systemsPaul Moore2014-02-091-0/+2
| | | | | | | | | | | | | | There are two major issues resolved in this patch: proper support for generating BPF on big endian systems, and ensuring we build the BPF correctly when the host system does not share the same endianess as the target platform. Relevant discussion in LKML regarding BPF on big endian systems: https://lkml.org/lkml/2012/4/8/87 Inspired by an earlier patch from Markos Chandras. Signed-off-by: Paul Moore <pmoore@redhat.com>
* all: convert some booleans from ints to boolsPaul Moore2013-04-191-3/+4
| | | | | | Make it more obvious that these variables are booleans. Signed-off-by: Paul Moore <pmoore@redhat.com>
* arch: remove direct access to the syscall tablesPaul Moore2013-03-261-1/+3
| | | | | | | | We may not always want to have statically defined syscall tables, e.g. x32, so create a series of functions to access the syscall tables which should provide us some flexibility. Signed-off-by: Paul Moore <pmoore@redhat.com>
* arch: rename arch-i386* to arch-x86*Paul Moore2013-03-261-0/+40
No code chanages here, just an effort to improve naming consistency a bit. Signed-off-by: Paul Moore <pmoore@redhat.com>
