| * [BRIDGE]: adding new device to bridge should enable if upAji Srinivas2007-03-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | One change introduced by the workqueue removal patch is that adding an interface that is up to a bridge which is also up does not ever call br_stp_enable_port(), leaving the port in DISABLED state until we do ifconfig down and up or link events occur. The following patch to the br_add_if function fixes it. This is a regression introduced in 2.6.21.

| | | | | | | | | | | | | | | | | | Now that we add the IPv6 device at registration time we don't need to set IF_READY in ipv6_add_dev anymore because we will always get a NETDEV_UP event later on should the device ever become ready.

| * [IPSEC]: xfrm audit hook misplaced in pfkey_delete and xfrm_del_saEric Paris2007-03-082-6/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | Inside pfkey_delete and xfrm_del_sa the audit hooks were not called if there was any permission/security failures in attempting to do the del operation (such as permission denied from security_xfrm_state_delete). This patch moves the audit hook to the exit path such that all failures (and successes) will actually get audited.

| * [IPSEC]: Add xfrm policy change auditing to pfkey_spdgetEric Paris2007-03-081-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | pfkey_spdget neither had an LSM security hook nor auditing for the removal of xfrm_policy structs. The security hook was added when it was moved into xfrm_policy_byid instead of the callers to that function by my earlier patch and this patch adds the auditing hooks as well.

| * [IPSEC]: xfrm_policy delete security check misplacedEric Paris2007-03-084-18/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The security hooks to check permissions to remove an xfrm_policy were actually done after the policy was removed. Since the unlinking and deletion are done in xfrm_policy_by* functions this moves the hooks inside those 2 functions. There we have all the information needed to do the security check and it can be done before the deletion. Since auditing requires the result of that security check err has to be passed back and forth from the xfrm_policy_by* functions. This patch also fixes a bug where a deletion that failed the security check could cause improper accounting on the xfrm_policy (xfrm_get_policy didn't have a put on the exit path for the hold taken by xfrm_policy_by*) It also fixes the return code when no policy is found in xfrm_add_pol_expire. In old code (at least back in the 2.6.18 days) err wasn't used before the return when no policy is found and so the initialization would cause err to be ENOENT. But since err has since been used above when we don't get a policy back from the xfrm_policy_by* function we would always return 0 instead of the intended ENOENT. Also fixed some white space damage in the same area.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts an earlier patch which disabled bidirectional mode, meaning that a listening (passive) socket was not allowed to write to the other (active) end of the connection. This mode had been disabled when there were problems with CCID3, but it imposes a constraint on socket programming and thus hinders deployment. A change is included to ignore RX feedback received by the TX CCID3 module. Many thanks to Andre Noll for pointing out this issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem I encountered while running bonnie++. When you have one thread that opens a file and starts to write to it, and then another thread that tries to open and write to the same file, the second thread will loop forever trying to grab the inode lock for that inode. Basically we come in through generic_buffered_file_write, which calls gfs2_prepare_write, which then attempts to grab the glock. Because we don't own the lock, gfs2_prepare_write gets GLR_TRYFAILED, which returns AOP_TRUNCATED_PAGE to generic_buffered_file_write. At this point generic_buffered_file_write loops around again and immediately retries the prepare_write. This means that the second process never gets off of the processor in order to allow the process that holds the lock to finish its work and let go of the lock. This patch makes gfs2_glock_nq schedule() if it gets back a GLR_TRYFAILED, which resolves this problem.

| * | sh: Fix kernel thread stack corruption with preempt.Hideo Saito2007-03-051-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I run a preemptive kernel-2.6.20 for SH7780, a created kthread(pdflush) can not exit by do_exit() in kernel_thread_helper. I think that the created kthread should have a room for 'struct pt_regs' space on the stack top, because __switch_to() will refer to the space as follows using 'regs = task_pt_regs(prev)' and next condition may be true.
