* [XFRM]: Fix missing protocol comparison of larval SAs.Joy Latten2007-03-12
| | | | | | | | | | | | | | I noticed that in xfrm_state_add we look for the larval SA in a few places without checking for protocol match. So when using both AH and ESP, whichever one gets added first, deletes the larval SA. It seems AH always gets added first and ESP is always the larval SA's protocol since the xfrm->tmpl has it first. Thus causing the additional km_query() Adding the check eliminates accidental double SA creation. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: David S.

* [NetLabel]: parse the CIPSO ranged tag on incoming packetsPaul Moore2007-03-12
| | | | | | | | | | | | | | | Commit 484b366932be0b73a22c74a82748ca10a721643e added support for the CIPSO ranged categories tag. However, it appears that I made a mistake when rebasing then patch to the latest upstream sources for submission and dropped the part of the patch that actually parses the tag on incoming packets. This patch fixes this mistake by adding the required function call to the cipso_v4_skbuff_getattr() function. I've run this patch over the weekend and have not noticed any problems.

* [DCCP]: Initialise write_xmit_timer also on passive socketsGerrit Renker2007-03-09
| | | | | | | | | | | | | | | | | | The TX CCID needs the write_xmit_timer for delaying packet sends. Previously this timer was only activated on active (connecting) sockets. This patch initialises the write_xmit_timer in sync with the other timers, i.e. the timer will be ready on any socket. This is used by applications with a listening socket which start to stream after receiving an initiation by the client. The write_xmit_timer is stopped when the application closes, as before. Was tested to work and to remove the timer bug reported on dccp@vger. Also moved timer initialisation into timer.c (static).

* [PATCH] bluetooth: fix socket locking in hci_sock_dev_event()Jiri Kosina2007-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Bluetooth] Fix socket locking in hci_sock_dev_event() hci_sock_dev_event() uses bh_lock_sock() to lock the socket lock. This is not deadlock-safe against locking of the same socket lock in l2cap_connect_cfm() from softirq context. In addition to that, hci_sock_dev_event() doesn't seem to be called from softirq context, so it is safe to use lock_sock()/release_sock() instead. The lockdep warning can be triggered on my T42p simply by switching the Bluetooth off by the keyboard button. ================================= [ INFO: inconsistent lock state ] 2.6.21-rc2 #4 --------------------------------- inconsistent {in-softirq-W} -> {softirq-on-W} usage. khubd/156 [HC0[0]:SC0[0]:HE1:SE1] takes: (slock-AF_BLUETOOTH){-+..}, at: [<e0ca5520>] hci_sock_dev_event+0xa8/0xc5 [bluetooth] {in-softirq-W} state was registered at: [<c012d1db>] mark_lock+0x59/0x414 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c012dfd7>] __lock_acquire+0x3e5/0xb99 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c012e7f2>] lock_acquire+0x67/0x81 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c036ee72>] _spin_lock+0x29/0x34 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<e0ca17c3>] hci_send_cmd+0x126/0x14f [bluetooth] [<e0ca4ce4>] hci_event_packet+0x729/0xebd [bluetooth] [<e0ca205b>] hci_rx_task+0x2a/0x20f [bluetooth] [<e0ca209d>] hci_rx_task+0x6c/0x20f [bluetooth] [<c012d7be>] trace_hardirqs_on+0x10d/0x14e [<c011ac85>] tasklet_action+0x3d/0x68 [<c011abba>] __do_softirq+0x41/0x92 [<c011ac32>] do_softirq+0x27/0x3d [<c0105134>] do_IRQ+0x7b/0x8f [<c0103dec>] common_interrupt+0x24/0x34 [<c0103df6>] common_interrupt+0x2e/0x34 [<c0248e65>] acpi_processor_idle+0x1b3/0x34a [<c0248e68>] acpi_processor_idle+0x1b6/0x34a [<c010232b>] cpu_idle+0x39/0x4e [<c04bab0c>] start_kernel+0x372/0x37a [<c04ba42b>] unknown_bootoption+0x0/0x202 [<ffffffff>] 0xffffffff Signed-off-by: Jiri Kosina <jkosina@suse.cz> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* [BRIDGE]: adding new device to bridge should enable if upAji Srinivas2007-03-07
| | | | | | | | | | | | | | 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.

* [IPSEC]: Add xfrm policy change auditing to pfkey_spdgetEric Paris2007-03-07
| | | | | | | | | | | | pfkey_spdget neither had an LSM security hook nor auditing for the removal of xfrm_policy structs.

* [IPSEC]: xfrm_policy delete security check misplacedEric Paris2007-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [DCCP]: Revert patch which disables bidirectional modeGerrit Renker2007-03-07
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix {nf,ip}_ct_iterate_cleanup unconfirmed list handling: - unconfirmed entries can not be killed manually, they are removed on confirmation or final destruction of the conntrack entry, which means we might iterate forever without making forward progress. This can happen in combination with the conntrack event cache, which holds a reference to the conntrack entry, which is only released when the packet makes it all the way through the stack or a different packet is handled. - taking references to an unconfirmed entry and using it outside the locked section doesn't work, the list entries are not refcounted and another CPU might already be waiting to destroy the entry What the code really wants to do is make sure the references of the hash table to the selected conntrack entries are released, so they will be destroyed once all references from skbs and the event cache are dropped. Since unconfirmed entries haven't even entered the hash yet, simply mark them as dying and skip confirmation based on that.

| * | bonding: Improve IGMP join processingJay Vosburgh2007-03-06
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In active-backup mode, the current bonding code duplicates IGMP traffic to all slaves, so that switches are up to date in case of a failover from an active to a backup interface. If bonding then fails back to the original active interface, it is likely that the "active slave" switch's IGMP forwarding for the port will be out of date until some event occurs to refresh the switch (e.g., a membership query). This patch alters the behavior of bonding to no longer flood IGMP to all ports, and to issue IGMP JOINs to the newly active port at the time of a failover. This insures that switches are kept up to date for all cases. "GOELLESCH Niels" <niels.goellesch@eurocontrol.int> originally reported this problem, and included a patch. His original patch was modified by Jay Vosburgh to additionally remove the existing IGMP flood behavior, use RCU, streamline code paths, fix trailing white space, and adjust for style.

* | [PATCH] knfsd: provide sunrpc pool_mode module optionGreg Banks2007-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to choose the mode for mapping NFS thread service pools to CPUs. Values are: auto choose a mapping mode heuristically global (default, same as the pre-2.6.19 code) a single global pool percpu one pool per CPU pernode one pool per NUMA node Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch makes the default "global". The pool mode can be changed after boot/modprobe using /sys, if the NFS and lockd services have been shut down. A useful side effect of this change is to fix a small memory leak when unloading the module.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | server When the last thread of nfsd exits, it shuts down all related sockets. It currently uses svc_close_socket to do this, but that only is immediately effective if the socket is not SK_BUSY. If the socket is busy - i.e. if a request has arrived that has not yet been processes - svc_close_socket is not effective and the shutdown process spins. So create a new svc_force_close_socket which removes the SK_BUSY flag is set and then calls svc_close_socket. Also change some open-codes loops in svc_destroy to use list_for_each_entry_safe.

* | [PATCH] knfsd: use recv_msg to get peer address for NFSD instead of code-copyingNeilBrown2007-03-06
|/ | | | | | | | | | | | | | | | The sunrpc server code needs to know the source and destination address for UDP packets so it can reply properly. It currently copies code out of the network stack to pick the pieces out of the skb. This is ugly and causes compile problems with the IPv6 stuff. So, rip that out and use recv_msg instead. This is a much cleaner interface, but has a slight cost in that the checksum is now checked before the copy, so we don't benefit from doing both at the same time. This can probably be fixed.

* [VLAN]: Avoid a 4-order allocation.Dan Aloni2007-03-02
| | | | | | | | | | | | | | This patch splits the vlan_group struct into a multi-allocated struct. On x86_64, the size of the original struct is a little more than 32KB, causing a 4-order allocation, which is prune to problems caused by buddy-system external fragmentation conditions. I couldn't just use vmalloc() because vfree() cannot be called in the softirq context of the RCU callback.

* [NetLabel]: Verify sensitivity level has a valid CIPSO mappingPaul Moore2007-03-02
| | | | | | | | | | | | | | | The current CIPSO engine has a problem where it does not verify that the given sensitivity level has a valid CIPSO mapping when the "std" CIPSO DOI type is used. The end result is that bad packets are sent on the wire which should have never been sent in the first place. This patch corrects this problem by verifying the sensitivity level mapping similar to what is done with the category mapping. This patch also changes the returned error code in this case to -EPERM to better match what the category mapping verification code returns.
