From 6ce74ec75ca690c4fb3a3c5f8b7767d094d93215 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Thu, 16 Feb 2012 15:08:39 -0500 Subject: SELinux: include flow.h where used rather than get it indirectly We use flow_cache_genid in the selinux xfrm files. This is declared in net/flow.h However we do not include that file directly anywhere. We have always just gotten it through a long chain of indirect .h file includes. on x86_64: CC security/selinux/ss/services.o In file included from /next/linux-next-20120216/security/selinux/ss/services.c:69:0: /next/linux-next-20120216/security/selinux/include/xfrm.h: In function 'selinux_xfrm_notify_policyload': /next/linux-next-20120216/security/selinux/include/xfrm.h:51:14: error: 'flow_cache_genid' undeclared (first use in this function) /next/linux-next-20120216/security/selinux/include/xfrm.h:51:14: note: each undeclared identifier is reported only once for each function it appears in make[3]: *** [security/selinux/ss/services.o] Error 1 Reported-by: Randy Dunlap Signed-off-by: Eric Paris --- net/xfrm/xfrm_policy.c | 1 + 1 file changed, 1 insertion(+) (limited to 'net') diff --git a/net/xfrm/xfrm_policy.c b/net/xfrm/xfrm_policy.c index 7661576b6f4..596f125658f 100644 --- a/net/xfrm/xfrm_policy.c +++ b/net/xfrm/xfrm_policy.c @@ -26,6 +26,7 @@ #include #include #include +#include #include #include #ifdef CONFIG_XFRM_STATISTICS -- cgit v1.2.3 From 46b325c7eb01482674406701825ff67f561ccdd4 Mon Sep 17 00:00:00 2001 From: Will Drewry Date: Thu, 12 Apr 2012 16:47:52 -0500 Subject: sk_run_filter: add BPF_S_ANC_SECCOMP_LD_W Introduces a new BPF ancillary instruction that all LD calls will be mapped through when skb_run_filter() is being used for seccomp BPF. The rewriting will be done using a secondary chk_filter function that is run after skb_chk_filter. The code change is guarded by CONFIG_SECCOMP_FILTER which is added, along with the seccomp_bpf_load() function later in this series.
