2005-04-24[SELINUX]: Fix ipv6_skip_exthdr() invocation causing OOPS.Herbert Xu
The SELinux hooks invoke ipv6_skip_exthdr() with an incorrect length final argument. However, the length argument turns out to be superfluous. I was just reading ipv6_skip_exthdr and it occured to me that we can get rid of len altogether. The only place where len is used is to check whether the skb has two bytes for ipv6_opt_hdr. This check is done by skb_header_pointer/skb_copy_bits anyway. Now it might appear that we've made the code slower by deferring the check to skb_copy_bits. However, this check should not trigger in the common case so this is OK. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-04-18[PATCH] SELinux: fix deadlock on dcache lockStephen Smalley
This fixes a deadlock on the dcache lock detected during testing at IBM by moving the logging of the current executable information from the SELinux avc_audit function to audit_log_exit (via an audit_log_task_info helper) for processing upon syscall exit. For consistency, the patch also removes the logging of other task-related information from avc_audit, deferring handling to audit_log_exit instead. This allows simplification of the avc_audit code, allows the exe information to be obtained more reliably, always includes the comm information (useful for scripts), and avoids including bogus task information for checks performed from irq or softirq.

2005-04-16[PATCH] SELinux: add support for NETLINK_KOBJECT_UEVENTJames Morris
This patch adds SELinux support for the KOBJECT_UEVENT Netlink family, so that SELinux can apply finer grained controls to it. For example, security policy for hald can be locked down to the KOBJECT_UEVENT Netlink family only. Currently, this family simply defaults to the default Netlink socket class. Note that some new permission definitions are added to sync with changes in the core userspace policy package, which auto-generates header files.

2005-04-16[PATCH] SELinux: fix bug in Netlink message type detectionJames Morris
This patch fixes a bug in the SELinux Netlink message type detection code, where the wrong constant was being used in a case statement. The incorrect value is not valid for this class of object so it would not have been reached, and fallen through to a default handler for all Netlink messages.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
