2012-12-038139cp: properly support change of MTU values [v2]John Greene
The 8139cp driver has a change_mtu function that has not been enabled since the dawn of the git repository. However, the generic eth_change_mtu is not used in its place, so that invalid MTU values can be set on the interface. Original patch salvages the broken code for the single case of setting the MTU while the interface is down, which is safe and also includes the range check. Now enhanced to support up or down interface. v2: fix case where rxbufsz isn't changed in the up state case Original patch from http://lkml.indiana.edu/hypermail/linux/kernel/1202.2/00770.html Testing: has been test on virtual 8139cp setup without issue, have no access real hardware 8139cp, need testing help.

2012-12-03arm64: use new common dtc ruleStephen Warren
The current rules have the .dtb files build in a different directory from the .dts files. This patch changes arm64 to use the generic dtb rule which builds .dtb files in the same directory as the source .dts. This requires moving parts of arch/arm64/boot/Makefile into newly created arch/arm64/boot/dts/Makefile, and updating arch/arm64/Makefile to call the new Makefile.

2012-12-03tuntap: attach queue 0 before registering netdeviceJason Wang
We attach queue 0 after registering netdevice currently. This leads to call netif_set_real_num_{tx|rx}_queues() after registering the netdevice. Since we allow tun/tap has a maximum of 1024 queues, this may lead a huge number of uevents to be injected to userspace since we create 2048 kobjects and then remove 2046. Solve this problem by attaching queue 0 and set the real number of queues before registering netdevice.

2012-12-03sctp: Add support to per-association statistics via a new ↵Michele Baldessari
SCTP_GET_ASSOC_STATS call The current SCTP stack is lacking a mechanism to have per association statistics. This is an implementation modeled after OpenSolaris' SCTP_GET_ASSOC_STATS. Userspace part will follow on lksctp if/when there is a general ACK on this. V4: - Move ipackets++ before q->immediate.func() for consistency reasons - Move sctp_max_rto() at the end of sctp_transport_update_rto() to avoid returning bogus RTO values - return asoc->rto_min when max_obs_rto value has not changed V3: - Increase ictrlchunks in sctp_assoc_bh_rcv() as well - Move ipackets++ to sctp_inq_push() - return 0 when no rto updates took place since the last call V2: - Implement partial retrieval of stat struct to cope for future expansion - Kill the rtxpackets counter as it cannot be precise anyway - Rename outseqtsns to outofseqtsns to make it clearer that these are out of sequence unexpected TSNs - Move asoc->ipackets++ under a lock to avoid potential miscounts - Fold asoc->opackets++ into the already existing asoc check - Kill unneeded (q->asoc) test when increasing rtxchunks - Do not count octrlchunks if sending failed (SCTP_XMIT_OK != 0) - Don't count SHUTDOWNs as SACKs - Move SCTP_GET_ASSOC_STATS to the private space API - Adjust the len check in sctp_getsockopt_assoc_stats() to allow for future struct growth - Move association statistics in their own struct - Update idupchunks when we send a SACK with dup TSNs - return min_rto in max_rto when RTO has not changed.

2012-12-03xfs: fix sparse reported log CRC endian issueDave Chinner
Not a bug as such, just warning noise from the xlog_cksum() returning a __be32 type when it should be returning a __le32 type.

(And yes I realize it might as well have > been me who did that back in the idea, but I still have no idea why) Because the CRC always returns the calcuation LE format, even on BE systems. So rather than always having to byte swap it everywhere and have all the force casts and anootations for sparse, it seems simpler to just make it a __le32 everywhere....

2012-12-03s390/cio: fix pgid reserved checkSebastian Ott
The check to whom a device is reserved is done by checking the path state of the affected channel paths. If it turns out that one path is flagged as reserved by someone else the whole device is marked as such. However the meaning of the RESVD_ELSE bit is that the addressed device is reserved to a different pathgroup (and not reserved to a different LPAR). If we do this test on a path which is currently not a member of the pathgroup we could erroneously mark the device as reserved to someone else. To fix this collect the reserved state for all potential members of the pathgroup and only mark the device as reserved if all of those potential members have the RESVD_ELSE bit set.

The patch addresses the issue by comparing the outgoing interface directly with the masqueraded interface in the nat table.

Add stricter checking for a few attributes. Note that these changes don't fix any bug in the current code base. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-12-03netfilter: kill support for per-af queue backendsFlorian Westphal
We used to have several queueing backends, but nowadays only nfnetlink_queue remains. In light of this there doesn't seem to be a good reason to support per-af registering -- just hook up nfnetlink_queue on module load and remove it on unload. This means that the userspace BIND/UNBIND_PF commands are now obsolete; the kernel will ignore them.

2012-12-03netfilter: ctnetlink: dump entries from the dying and unconfirmed listsPablo Neira Ayuso
This patch adds a new operation to dump the content of the dying and unconfirmed lists. Under some situations, the global conntrack counter can be inconsistent with the number of entries that we can dump from the conntrack table. The way to resolve this is to allow dumping the content of the unconfirmed and dying lists, so far it was not possible to look at its content. This provides some extra instrumentation to resolve problematic situations in which anyone suspects memory leaks. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-12-03netfilter: nf_conntrack: improve nf_conn object traceabilityPablo Neira Ayuso
This patch modifies the conntrack subsystem so that all existing allocated conntrack objects can be found in any of the following places: * the hash table, this is the typical place for alive conntrack objects. * the unconfirmed list, this is the place for newly created conntrack objects that are still traversing the stack. * the dying list, this is where you can find conntrack objects that are dying or that should die anytime soon (eg. once the destroy event is delivered to the conntrackd daemon). Thus, we make sure that we follow the track for all existing conntrack objects. This patch, together with some extension of the ctnetlink interface to dump the content of the dying and unconfirmed lists, will help in case to debug suspected nf_conn object leaks.

2012-12-03netfilter: ipset: Increase the number of maximal sets automaticallyJozsef Kadlecsik
The max number of sets was hardcoded at kernel cofiguration time and could only be modified via a module parameter. The patch adds the support of increasing the max number of sets automatically, as needed. The array of sets is incremented by 64 new slots if we run out of empty slots. The absolute limit for the maximal number of sets is limited by 65534. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-12-03ARM: 7587/1: implement optimized percpu variable accessRob Herring
Use the previously unused TPIDRPRW register to store percpu offsets. TPIDRPRW is only accessible in PL1, so it can only be used in the kernel. This replaces 2 loads with a mrc instruction for each percpu variable access. With hackbench, the performance improvement is 1.4% on Cortex-A9 (highbank). Taking an average of 30 runs of "hackbench -l 1000" yields: Before: 6.2191 After: 6.1348 Will Deacon reported similar delta on v6 with 11MPCore. The asm "memory clobber" are needed here to ensure the percpu offset gets reloaded. Testing by Will found that this would not happen in __schedule() which is a bit of a special case as preemption is disabled but the execution can move cores.
