* [NETFILTER]: make secmark_tg_destroy() staticAdrian Bunk2008-02-141-1/+1
| | | | | | | This patch makes the needlessly global secmark_tg_destroy() static. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* SELinux: Enable dynamic enable/disable of the network access checksPaul Moore2008-01-291-1/+12
| | | | | | | | | | | | | | | | | | | | | | This patch introduces a mechanism for checking when labeled IPsec or SECMARK are in use by keeping introducing a configuration reference counter for each subsystem. In the case of labeled IPsec, whenever a labeled SA or SPD entry is created the labeled IPsec/XFRM reference count is increased and when the entry is removed it is decreased. In the case of SECMARK, when a SECMARK target is created the reference count is increased and later decreased when the target is removed. These reference counters allow SELinux to quickly determine if either of these subsystems are enabled. NetLabel already has a similar mechanism which provides the netlbl_enabled() function. This patch also renames the selinux_relabel_packet_permission() function to selinux_secmark_relabel_packet_permission() as the original name and description were misleading in that they referenced a single packet label which is not the case.

* [SECURITY] secmark: nul-terminate secdataJames Morris2006-08-021-0/+2
| | | | | | | | | | | | | | | | | The patch below fixes a problem in the iptables SECMARK target, where the user-supplied 'selctx' string may not be nul-terminated. From initial analysis, it seems that the strlen() called from selinux_string_to_sid() could run until it arbitrarily finds a zero, and possibly cause a kernel oops before then. The impact of this appears limited because the operation requires CAP_NET_ADMIN, which is essentially always root. Also, the module is not yet in wide use.

* [SECMARK]: Add xtables SECMARK targetJames Morris2006-06-181-0/+156
Add a SECMARK target to xtables, allowing the admin to apply security marks to packets via both iptables and ip6tables. The target currently handles SELinux security marking, but can be extended for other purposes as needed.
