2012-11-15sctp: fix /proc/net/sctp/ memory leakTommi Rantala1-4/+4
Commit 13d782f ("sctp: Make the proc files per network namespace.") changed the /proc/net/sctp/ struct file_operations opener functions to use single_open_net() and seq_open_net(). Avoid leaking memory by using single_release_net() and seq_release_net() as the release functions. Discovered with Trinity (the syscall fuzzer).

2012-11-15sit: fix sparse warningsNicolas Dichtel1-5/+5
This change fixes several sparse warnings about endianness problem. The wrong nla_*() functions were used. It also fix a sparse warning about a flag test (field i_flags). This field is used in this file like a local flag only, so it is more an u16 (gre uses it as a be16). This sparse warning was already there before the patch that add netlink management, the code has just been moved.

2012-11-15xfrm: Use a static gc threshold value for ipv6Steffen Klassert1-15/+1
Unlike ipv4 did, ipv6 does not handle the maximum number of cached routes dynamically. So no need to try to handle the IPsec gc threshold value dynamically. This patch sets the IPsec gc threshold value back to 1024 routes, as it is for non-IPsec routes. Signed-off-by: Steffen Klassert <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== Included is a Bluetooth pull -- Gustavo says: "These are the Bluetooth bits for inclusion in 3.8, there is basically one big thing here which is the High Speed patches from Andrei, he did a lot of work on A2MP and management of AMP devices. The rest are mostly clean up and bug fixes." Also included is an NFC pull -- Samuel says: "With this one we have: - pn544 p2p support. - pn544 physical and HCI layers separation. We are getting the pn544 driver ready to support non i2c physical layers. - LLCP SNL (Service Name Lookup). This is the NFC p2p service discovery protocol. - LLCP datagram sockets (connection less) support. - IDR library usage for NFC devices indexes assignement. - NFC netlink extension for setting and getting LLCP link characteristics. - Various code style fixes and cleanups spread over the pn533, LLCP, HCI and pn544 code." There are a couple of mac80211 pulls as well -- Johannes says: "Please pull my mac80211-next tree to get the first round of new features for 3.8. We have: * finally, the mac80211 multi-channel work * scan improvements: - bg scan - scan flush - forced AP scan * cfg80211 tracing * a bit of new code to allow implementing SAE (secure authentication of equals) in managed mode Along with a few random improvements, features and fixes." and... "Please pull from mac80211-next (per below pull request) to get a few updates. Most important is probably the fix for the WDS regression that my previous pull request introduced. Other than that, I have some tracing code, two mesh updates and a change to allow drivers to calculate the AES CMAC subkeys without having to implement the GF_mulx operation themselves." On top of that are the usual updates to iwlwifi, ath9k, rt2x00, brcmfmac, mwifiex, and a few others here and there. Of note is the addition of the ar5523 driver, ported from an original FreeBSD driver. ==================== Signed-off-by: David S. Miller <[email protected]>

2012-11-14ipv4/ip_vti.c: VTI fix post-decryption forwardingSaurabh Mohan1-0/+5
With the latest kernel there are two things that must be done post decryption so that the packet are forwarded. 1. Remove the mark from the packet. This will cause the packet to not match the ipsec-policy again. However doing this causes the post-decryption check to fail also and the packet will get dropped. (cat /proc/net/xfrm_stat). 2. Remove the sp association in the skbuff so that no policy check is done on the packet for VTI tunnels. Due to #2 above we must now do a security-policy check in the vti rcv path prior to resetting the mark in the skbuff.

2012-11-14bridge: add root port blockingstephen hemminger4-2/+28
This is Linux bridge implementation of root port guard. If BPDU is received from a leaf (edge) port, it should not be elected as root port. Why would you want to do this? If using STP on a bridge and the downstream bridges are not fully trusted; this prevents a hostile guest for rerouting traffic. Why not just use netfilter? Netfilter does not track of follow spanning tree decisions. It would be difficult and error prone to try and mirror STP resolution in netfilter module.

2012-11-14bridge: implement BPDU blockingstephen hemminger4-1/+15
This is Linux bridge implementation of STP protection (Cisco BPDU guard/Juniper BPDU block). BPDU block disables the bridge port if a STP BPDU packet is received. Why would you want to do this? If running Spanning Tree on bridge, hostile devices on the network may send BPDU and cause network failure. Enabling bpdu block will detect and stop this. How to recover the port? The port will be restarted if link is brought down, or removed and reattached.

2012-11-14bridge: bridge port parameters over netlinkstephen hemminger1-33/+132
Expose bridge port parameter over netlink. By switching to a nested message, this can be used for other bridge parameters. This changes IFLA_PROTINFO attribute from one byte to a full nested set of attributes. This is safe for application interface because the old message used IFLA_PROTINFO and new one uses IFLA_PROTINFO | NLA_F_NESTED. The code adapts to old format requests, and therefore stays compatible with user mode RSTP daemon. Since the type field for nested and unnested attributes are different, and the old code in libnetlink doesn't do the mask, it is also safe to use with old versions of bridge monitor command. Note: although mode is only a boolean, treating it as a full byte since in the future someone will probably want to add more values (like macvlan has).

2012-11-14batman-adv: roaming handling mechanism redesignAntonio Quartulli1-39/+118
This patch allows clients to roam multiple times within the same originator-interval. To enable this new feature two key aspects that have been introduced: 1) packets are always directed to the node that was originally serving the roamed client which will then re-route the data to the correct destination at any point in time; 2) the client flags handling mechanism has been properly modified in order to allow multiple roamings withinin the same orig-int. Therefore flags are now set properly even in this scenario. Signed-off-by: Antonio Quartulli <[email protected]>
2012-11-14batman-adv: refactor tt_global_del_struct()Antonio Quartulli1-10/+9
batadv_tt_global_del_struct() function is not properly named. Having a more meaningful name which reflects the current behavior helps other developers to easily understand what it does.

2012-11-14batman-adv: substitute tt_poss_change with a per-tt_entry flagAntonio Quartulli6-75/+156
tt_poss_change is a node-wide flag which tells whether the node is in a roaming state (a client recently moved to/away from it) in order to let it apply special re-routing rules. However this flag does not give a clear idea of the current state because it is not possible to understand *which client* is actually involved in the roaming. For this reason a better approach has been chosen: instead of using a node-wide variable, the roaming state is now given by a per-tt_entry ROAM flag which, in case of packet coming through the node, tells the node whether the real destination is in roaming state or not. With this flag change, batadv_check_unicast_ttvn() has also been rearranged in order to better fit the new re-routing logic and to be much more readable.

2012-11-14batman-adv: wait multiple periods before activating blaSimon Wunderlich3-1/+10
For some reasons (bridge forward delay, network device setup order, etc) the initial bridge loop avoidance announcement packets may be lost. This may lead to problems in finding other backbone gws, and therfore create loops in the startup time. Fix this by extending the waiting periods to 3 (define can be changed) before allowing broadcast traffic.

2012-11-14batman-adv: allow bla traffic only after first worker periodSimon Wunderlich1-1/+19
When adding a backbone gateway for the first time, it might not yet be known in the backbone, and therefore we should not forward broadcasts yet. This behaviour is the same as when sending a request to another backbone gw because of a CRC mismatch. The backbone gw will operate normal after the next periodic bla work.

2012-11-14batman-adv: send announcement when backbone gw is registeredSimon Wunderlich1-4/+10
To avoid loops in the startup phase until the first announcement is sent, send an announcement immediately as soon as a backbone gw is added.

2012-11-13tcp: tcp_replace_ts_recent() should not be called from tcp_validate_incoming()Eric Dumazet1-5/+10
We added support for RFC 5961 in latest kernels but TCP fails to perform exhaustive check of ACK sequence. We can update our view of peer tsval from a frame that is later discarded by tcp_ack() This makes timestamps enabled sessions vulnerable to injection of a high tsval : peers start an ACK storm, since the victim sends a dupack each time it receives an ACK from the other peer. As tcp_validate_incoming() is called before tcp_ack(), we should not peform tcp_replace_ts_recent() from it, and let callers do it at the right time.
