2014-07-31netfilter: nfnetlink_acct: avoid using NFACCT_F_OVERQUOTA with bit helper ↵Alexey Perevalov
functions Bit helper functions were used for manipulation with NFACCT_F_OVERQUOTA, but they are accepting pit position, but not a bit mask. As a result not a third bit for NFACCT_F_OVERQUOTA was set, but forth. Such behaviour was dangarous and could lead to unexpected overquota report result.

2014-07-24netfilter: xt_hashlimit: perform garbage collection from process contextEric Dumazet
xt_hashlimit cannot be used with large hash tables, because garbage collector is run from a timer. If table is really big, its possible to hold cpu for more than 500 msec, which is unacceptable. Switch to a work queue, and use proper scheduling points to remove latencies spikes. Later, we also could switch to a smoother garbage collection done at lookup time, one bucket at a time...

2014-07-22netfilter: nf_tables: simplify set dump through netlinkPablo Neira Ayuso
This patch uses the cb->data pointer that allows us to store the context when dumping the set list. Thus, we don't need to parse the original netlink message containing the dump request for each recvmsg() call when dumping the set list. The different function flavours depending on the dump criteria has been also merged into one single generic function. This saves us ~100 lines of code.

2014-07-22af_iucv: avoid path quiesce of severed path in shutdown()Ursula Braun
An af_iucv stress test showed -EPIPE results for sendmsg() calls. They are caused by quiescing a path even though it has been already severed by peer. For IUCV transport shutdown() consists of 2 steps: (1) sending the shutdown message to peer (2) quiescing the iucv path If the iucv path between these 2 steps is severed due to peer closing the path, the quiesce step is no longer needed.

Antonio Quartulli says: ==================== pull request [net]: batman-adv 20140721 here you have two fixes that we have been testing for quite some time (this is why they arrived a bit late in the rc cycle). Patch 1) ensures that BLA packets get dropped and not forwarded to the mesh even if they reach batman-adv within QinQ frames. Forwarding them into the mesh means messing up with the TT database of other nodes which can generate all kind of unexpected behaviours during route computation. Patch 2) avoids a couple of race conditions triggered upon fast VLAN deletion-addition. Such race conditions are pretty dangerous because they not only create inconsistencies in the TT database of the nodes in the network, but such scenario is also unrecoverable (unless nodes are rebooted). ==================== Signed-off-by: David S.

2014-07-21tracing: Fix wraparound problems in "uptime" trace clockTony Luck
The "uptime" trace clock added in: commit 8aacf017b065a805d27467843490c976835eb4a5 tracing: Add "uptime" trace clock that uses jiffies has wraparound problems when the system has been up more than 1 hour 11 minutes and 34 seconds. It converts jiffies to nanoseconds using: (u64)jiffies_to_usecs(jiffy) * 1000ULL but since jiffies_to_usecs() only returns a 32-bit value, it truncates at 2^32 microseconds. An additional problem on 32-bit systems is that the argument is "unsigned long", so fixing the return value only helps until 2^32 jiffies (49.7 days on a HZ=1000 system). Avoid these problems by using jiffies_64 as our basis, and not converting to nanoseconds (we do convert to clock_t because user facing API must not be dependent on internal kernel HZ values).

2014-07-21batman-adv: fix TT VLAN inconsistency on VLAN re-addAntonio Quartulli
When a VLAN interface (on top of batX) is removed and re-added within a short timeframe TT does not have enough time to properly cleanup. This creates an internal TT state mismatch as the newly created softif_vlan will be initialized from scratch with a TT client count of zero (even if TT entries for this VLAN still exist). The resulting TT messages are bogus due to the counter / tt client listing mismatch, thus creating inconsistencies on every node in the network To fix this issue destroy_vlan() has to not free the VLAN object immediately but it has to be kept alive until all the TT entries for this VLAN have been removed. destroy_vlan() still removes the sysfs folder so that the user has the feeling that everything went fine. If the same VLAN is re-added before the old object is free'd, then the latter is resurrected and re-used. Implement such behaviour by increasing the reference counter of a softif_vlan object every time a new local TT entry for such VLAN is created and remove the object from the list only when all the TT entries have been destroyed.

2014-07-21batman-adv: drop QinQ claim frames in bridge loop avoidanceSimon Wunderlich
Since bridge loop avoidance only supports untagged or simple 802.1q tagged VLAN claim frames, claim frames with stacked VLAN headers (QinQ) should be detected and dropped. Transporting the over the mesh may cause problems on the receivers, or create bogus entries in the local tt tables.
