2014-01-27net: Fix memory leak if TPROXY used with TCP early demuxHolger Eitzenberger
I see a memory leak when using a transparent HTTP proxy using TPROXY together with TCP early demux and Kernel v3.8.13.15 (Ubuntu stable): unreferenced object 0xffff88008cba4a40 (size 1696): comm "softirq", pid 0, jiffies 4294944115 (age 8907.520s) hex dump (first 32 bytes): 0a e0 20 6a 40 04 1b 37 92 be 32 e2 e8 b4 00 00 .. j@..7..2..... 02 00 07 01 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<ffffffff810b710a>] kmem_cache_alloc+0xad/0xb9 [<ffffffff81270185>] sk_prot_alloc+0x29/0xc5 [<ffffffff812702cf>] sk_clone_lock+0x14/0x283 [<ffffffff812aaf3a>] inet_csk_clone_lock+0xf/0x7b [<ffffffff8129a893>] netlink_broadcast+0x14/0x16 [<ffffffff812c1573>] tcp_create_openreq_child+0x1b/0x4c3 [<ffffffff812c033e>] tcp_v4_syn_recv_sock+0x38/0x25d [<ffffffff812c13e4>] tcp_check_req+0x25c/0x3d0 [<ffffffff812bf87a>] tcp_v4_do_rcv+0x287/0x40e [<ffffffff812a08a7>] ip_route_input_noref+0x843/0xa55 [<ffffffff812bfeca>] tcp_v4_rcv+0x4c9/0x725 [<ffffffff812a26f4>] ip_local_deliver_finish+0xe9/0x154 [<ffffffff8127a927>] __netif_receive_skb+0x4b2/0x514 [<ffffffff8127aa77>] process_backlog+0xee/0x1c5 [<ffffffff8127c949>] net_rx_action+0xa7/0x200 [<ffffffff81209d86>] add_interrupt_randomness+0x39/0x157 But there are many more, resulting in the machine going OOM after some days. From looking at the TPROXY code, and with help from Florian, I see that the memory leak is introduced in tcp_v4_early_demux(): void tcp_v4_early_demux(struct sk_buff *skb) { /* ... */ iph = ip_hdr(skb); th = tcp_hdr(skb); if (th->doff < sizeof(struct tcphdr) / 4) return; sk = __inet_lookup_established(dev_net(skb->dev), &tcp_hashinfo, iph->saddr, th->source, iph->daddr, ntohs(th->dest), skb->skb_iif); if (sk) { skb->sk = sk; where the socket is assigned unconditionally to skb->sk, also bumping the refcnt on it. This is problematic, because in our case the skb has already a socket assigned in the TPROXY target. This then results in the leak I see. The very same issue seems to be with IPv6, but haven't tested. Reviewed-by: Florian Westphal <fw@strlen.de> Signed-off-by: Holger Eitzenberger <holger@eitzenberger.org> Signed-off-by: David S.

2014-01-27nfsd: consider CLAIM_FH when handing out delegationMing Chen
CLAIM_FH was added by NFSv4.1. It is the same as CLAIM_NULL except that it uses only current FH to identify the file to be opened. The NFS client is using CLAIM_FH if the FH is available when opening a file. Currently, we cannot get any delegation if we stat a file before open it because the server delegation code does not recognize CLAIM_FH. We tested this patch and found delegation can be handed out now when claim is CLAIM_FH.

Follow redirect replies from osds, for details see ceph.git commit fbbe3ad1220799b7bb00ea30fce581c5eadaf034. v1 (current) version of redirect reply consists of oloc and oid, which expands to pool, key, nspace, hash and oid. However, server-side code that would populate anything other than pool doesn't exist yet, and hence this commit adds support for pool redirects only. To make sure that future server-side updates don't break us, we decode all fields and, if any of key, nspace, hash or oid have a non-default value, error out with "corrupt osd_op_reply ..." message.

2014-01-27libceph: start using oloc abstractionIlya Dryomov
Instead of relying on pool fields in ceph_file_layout (for mapping) and ceph_pg (for enconding), start using ceph_object_locator (oloc) abstraction. Note that userspace oloc currently consists of pool, key, nspace and hash fields, while this one contains only a pool. This is OK, because at this point we only send (i.e. encode) olocs and never have to receive (i.e. decode) them. This makes keeping a copy of ceph_file_layout in every osd request unnecessary, so ceph_osd_request::r_file_layout field is nuked.

2014-01-27bonding: restructure locking of bond_ab_arp_probe()Veaceslav Falico
Currently we're calling it from under RCU context, however we're using some functions that require rtnl to be held. Fix this by restructuring the locking - don't call it under any locks, aquire rcu_read_lock() if we're sending _only_ (i.e. we have the active slave present), and use rtnl locking otherwise - if we need to modify (in)active flags of a slave.

As a result, a dev_WARN_ONCE will be hit during shutdown for every bnx2x VF probed on a hypervisor (as its shutdown callback will be called and later pci_disable_sriov() will call its remove callback).

2014-01-27nfsd4: fix delegation-unlink/rename raceJ. Bruce Fields

But a client performing an open-by-name, when it is returned a delegation, must be able to assume that the file is still linked at the name it was opened under.

2014-01-27drm/i915: Decouple GPU error reporting from ring initialisationChris Wilson
Currently we report through our error state only the rings that have been initialised (as detected by ring->obj). This check is done after the GPU reset and ring re-initialisation, which means that the software state may not be the same as when we captured the hardware error and we may not print out any of the vital information for debugging the hang.

2014-01-26net: stmmac: Log MAC address only onceHans de Goede
Logging the MAC address on every if-up, is not really useful, and annoying when there is no cable inserted and NetworkManager tries the ifup every 50 seconds. Also change the log level from warning to info, as that is what it is. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-01-26net: stmmac: Silence PTP init errors on hw without PTPHans de Goede
Logging a PTP error on hw which simply does not support PTP is not very useful. Moreover this message gets logged on every if-up, and if there is no cable inserted NetworkManager will re-try the ifup every 50 seconds.
