2014-11-19Bluetooth: Fix setting conn->pending_sec_level value from link keyJohan Hedberg
When a connection is requested the conn->pending_sec_level value gets set to whatever level the user requested the connection to be. During the pairing process there are various sanity checks to try to ensure that the right length PIN or right IO Capability is used to satisfy the target security level. However, when we finally get hold of the link key that is to be used we should still set the actual final security level from the key type. This way when we eventually get an Encrypt Change event the correct value gets copied to conn->sec_level.

2014-11-19Bluetooth: Fix setting state back to TASK_RUNNINGJohan Hedberg
In __hci_cmd_sync_ev() and __hci_req_sync() if the hci_req_run() call fails and we return from the functions we should ensure that the state doesn't remain in TASK_INTERRUPTIBLE that we just set it to. This patch fixes missing calls to set_current_state(TASK_RUNNING) in both places. Reported-by: Kirill A.

2014-11-18mac80211: minstrel_ht: fix a crash in rate sortingFelix Fietkau
The commit 5935839ad73583781b8bbe8d91412f6826e218a4 "mac80211: improve minstrel_ht rate sorting by throughput & probability" introduced a crash on rate sorting that occurs when the rate added to the sorting array is faster than all the previous rates. Due to an off-by-one error, it reads the rate index from tp_list[-1], which contains uninitialized stack garbage, and then uses the resulting index for accessing the group rate stats, leading to a crash if the garbage value is big enough.

2014-11-18Bluetooth: Call drain_workqueue() before resetting stateJohan Hedberg
Doing things like hci_conn_hash_flush() while holding the hdev lock is risky since its synchronous pending work cancellation could cause the L2CAP layer to try to reacquire the hdev lock.

2014-11-17bridge: fix netfilter/NF_BR_LOCAL_OUT for own, locally generated queriesLinus Lüssing
Ebtables on the OUTPUT chain (NF_BR_LOCAL_OUT) would not work as expected for both locally generated IGMP and MLD queries. The IP header specific filter options are off by 14 Bytes for netfilter (actual output on interfaces is fine). NF_HOOK() expects the skb->data to point to the IP header, not the ethernet one (while dev_queue_xmit() does not). Luckily there is an br_dev_queue_push_xmit() helper function already - let's just use that.

However, in MLD/IGMP code, we have some rather ugly AVAILABLE(skb) macros, which determine if we may end up doing an skb_put() for adding another record. To avoid possible fragmentation, we check the skb's tailroom as skb->dev->mtu - skb->len, which is a wrong assumption as the actual max allocation size can be much smaller. The IGMP case doesn't have this issue as commit 57e1ab6eaddc ("igmp: refine skb allocations") stores the allocation size in the cb[]. Set a reserved_tailroom to make it fit into the MTU and use skb_availroom() helper instead. This also allows to get rid of igmp_skb_size().

2014-11-16net: provide a per host RSS key generic infrastructureEric Dumazet
RSS (Receive Side Scaling) typically uses Toeplitz hash and a 40 or 52 bytes RSS key. Some drivers use a constant (and well known key), some drivers use a random key per port, making bonding setups hard to tune. Well known keys increase attack surface, considering that number of queues is usually a power of two. This patch provides infrastructure to help drivers doing the right thing. netdev_rss_key_fill() should be used by drivers to initialize their RSS key, even if they provide ethtool -X support to let user redefine the key later. A new /proc/sys/net/core/netdev_rss_key file can be used to get the host RSS key even for drivers not providing ethtool -x support, in case some applications want to precisely setup flows to match some RX queues. Tested: myhost:~# cat /proc/sys/net/core/netdev_rss_key 11:63:99:bb:79:fb:a5:a7:07:45:b2:20:bf:02:42:2d:08:1a:dd:19:2b:6b:23:ac:56:28:9d:70:c3:ac:e8:16:4b:b7:c1:10:53:a4:78:41:36:40:74:b6:15:ca:27:44:aa:b3:4d:72 myhost:~# ethtool -x eth0 RX flow hash indirection table for eth0 with 8 RX ring(s): 0: 0 1 2 3 4 5 6 7 RSS hash key: 11:63:99:bb:79:fb:a5:a7:07:45:b2:20:bf:02:42:2d:08:1a:dd:19:2b:6b:23:ac:56:28:9d:70:c3:ac:e8:16:4b:b7:c1:10:53:a4:78:41 Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2014-11-16dcbnl : Disable software interrupts before taking dcb_lockAnish Bhatt
Solves possible lockup issues that can be seen from firmware DCB agents calling into the DCB app api. DCB firmware event queues can be tied in with NAPI so that dcb events are generated in softIRQ context. This can results in calls to dcb_*app() functions which try to take the dcb_lock. If the the event triggers while we also have the dcb_lock because lldpad or some other agent happened to be issuing a get/set command we could see a cpu lockup. This code was not originally written with firmware agents in mind, hence grabbing dcb_lock from softIRQ context was not considered.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS fixes for net The following patchset contains Netfilter updates for your net tree, they are: 1) Fix missing initialization of the range structure (allocated in the stack) in nft_masq_{ipv4, ipv6}_eval, from Daniel Borkmann. 2) Make sure the data we receive from userspace contains the req_version structure, otherwise return an error incomplete on truncated input. From Dan Carpenter. 3) Fix handling og skb->sk which may cause incorrect handling of connections from a local process. Via Simon Horman, patch from Calvin Owens. 4) Fix wrong netns in nft_compat when setting target and match params structure. 5) Relax chain type validation in nft_compat that was recently included, this broke the matches that need to be run from the route chain type. Now iptables-test.py automated regression tests report success again and we avoid the only possible problematic case, which is the use of nat targets out of nat chain type. 6) Use match->table to validate the tablename, instead of the match->name. Again patch for nft_compat. 7) Restore the synchronous release of objects from the commit and abort path in nf_tables. This is causing two major problems: splats when using nft_compat, given that matches and targets may sleep and call_rcu is invoked from softirq context. Moreover Patrick reported possible event notification reordering when rules refer to anonymous sets. 8) Fix race condition in between packets that are being confirmed by conntrack and the ctnetlink flush operation. This happens since the removal of the central spinlock. Thanks to Jesper D. Brouer to looking into this. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-16ipv4: Fix incorrect error code when adding an unreachable routePanu Matilainen
Trying to add an unreachable route incorrectly returns -ESRCH if if custom FIB rules are present: [root@localhost ~]# ip route add 74.125.31.199 dev eth0 via 1.2.3.4 RTNETLINK answers: Network is unreachable [root@localhost ~]# ip rule add to 55.66.77.88 table 200 [root@localhost ~]# ip route add 74.125.31.199 dev eth0 via 1.2.3.4 RTNETLINK answers: No such process [root@localhost ~]# Commit 83886b6b636173b206f475929e58fac75c6f2446 ("[NET]: Change "not found" return value for rule lookup") changed fib_rules_lookup() to use -ESRCH as a "not found" code internally, but for user space it should be translated into -ENETUNREACH. Handle the translation centrally in ipv4-specific fib_lookup(), leaving the DECnet case alone. On a related note, commit b7a71b51ee37d919e4098cd961d59a883fd272d8 ("ipv4: removed redundant conditional") removed a similar translation from ip_route_input_slow() prematurely AIUI.

2014-11-15Bluetooth: Remove unnecessary hdev locking in smp.cJohan Hedberg
Now that the SMP related key lists are converted to RCU there is nothing in smp_cmd_sign_info() or smp_cmd_ident_addr_info() that would require taking the hdev lock (including the smp_distribute_keys call). This patch removes this unnecessary locking. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-11-15Bluetooth: Convert IRK list to RCUJohan Hedberg
This patch set converts the hdev->identity_resolving_keys list to use RCU to eliminate the need to use hci_dev_lock/unlock. An additional change that must be done is to remove use of CRYPTO_ALG_ASYNC for the hdev-specific AES crypto context. The reason is that this context is used for matching RPAs and the loop that does the matching is under the RCU read lock, i.e. is an atomic section which cannot sleep.

2014-11-15Bluetooth: Trigger SMP for the appropriate LE CoC errorsJohan Hedberg
The insufficient authentication/encryption errors indicate to the L2CAP client that it should try to elevate the security level. Since there really isn't any exception to this rule it makes sense to fully handle it on the kernel side instead of pushing the responsibility to user space. This patch adds special handling of these two error codes and calls smp_conn_security() with the elevated security level if necessary.
