93dc610 Jason Baron 16 March 2012, 20:34:03 UTC Don't limit non-nested epoll paths Commit 28d82dc1c4ed ("epoll: limit paths") that I did to limit the number of possible wakeup paths in epoll is causing a few applications to longer work (dovecot for one). The original patch is really about limiting the amount of epoll nesting (since epoll fds can be attached to other fds). Thus, we probably can allow an unlimited number of paths of depth 1. My current patch limits it at 1000. And enforce the limits on paths that have a greater depth.

c579bc7 Linus Torvalds 18 March 2012, 02:22:24 UTC Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net Pull networking changes from David Miller: "1) icmp6_dst_alloc() returns NULL instead of ERR_PTR() leading to crashes, particularly during shutdown. Reported by Dave Jones and fixed by Eric Dumazet. 2) hyperv and wimax/i2400m return NETDEV_TX_BUSY when they have already freed the SKB, which causes crashes as to the caller this means requeue the packet. Fixes from Eric Dumazet. 3) usbnet driver doesn't allocate the right amount of headroom on fresh RX SKBs, fix from Eric Dumazet. 4) Fix regression in ip6_mc_find_dev_rcu(), as an RCU lookup it abolutely should not take a reference to 'dev', this leads to leaks. Fix from RonQing Li. 5) Fix netfilter ctnetlink race between delete and timeout expiration. From Pablo Neira Ayuso. 6) Revert SFQ change which causes regressions, specifically queueing to tail can lead to unavoidable flow starvation. From Eric Dumazet. 7) Fix a memory leak and a crash on corrupt firmware files in bnx2x, from Michal Schmidt." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: netfilter: ctnetlink: fix race between delete and timeout expiration ipv6: Don't dev_hold(dev) in ip6_mc_find_dev_rcu. wimax/i2400m: fix erroneous NETDEV_TX_BUSY use net/hyperv: fix erroneous NETDEV_TX_BUSY use net/usbnet: reserve headroom on rx skbs bnx2x: fix memory leak in bnx2x_init_firmware() bnx2x: fix a crash on corrupt firmware file sch_sfq: revert dont put new flow at the end of flows ipv6: fix icmp6_dst_alloc() 18 March 2012, 02:22:24 UTC

c017386 Anton Blanchard 16 March 2012, 10:28:19 UTC afs: Remote abort can cause BUG in rxrpc code When writing files to afs I sometimes hit a BUG: kernel BUG at fs/afs/rxrpc.c:179! With a backtrace of: afs_free_call afs_make_call afs_fs_store_data afs_vnode_store_data afs_write_back_from_locked_page afs_writepages_region afs_writepages The cause is: ASSERT(skb_queue_empty(&call->rx_queue)); Looking at a tcpdump of the session the abort happens because we are exceeding our disk quota: rx abort fs reply store-data error diskquota exceeded (32) So the abort error is valid. We hit the BUG because we haven't freed all the resources for the call. By freeing any skbs in call->rx_queue before calling afs_free_call we avoid hitting leaking memory and avoid hitting the BUG.

cc34eb6 Eric Dumazet 13 March 2012, 18:04:25 UTC sch_sfq: revert dont put new flow at the end of flows This reverts commit d47a0ac7b6 (sch_sfq: dont put new flow at the end of flows) As Jesper found out, patch sounded great but has bad side effects. In stress situation, pushing new flows in front of the queue can prevent old flows doing any progress. Packets can stay in SFQ queue for unlimited amount of time. It's possible to add heuristics to limit this problem, but this would add complexity outside of SFQ scope. A more sensible answer to Dave Taht concerns (who reported the issued I tried to solve in original commit) is probably to use a qdisc hierarchy so that high prio packets dont enter a potentially crowded SFQ qdisc.

59927fb Hugh Dickins 15 March 2012, 22:17:07 UTC memcg: free mem_cgroup by RCU to fix oops After fixing the GPF in mem_cgroup_lru_del_list(), three times one machine running a similar load (moving and removing memcgs while swapping) has oopsed in mem_cgroup_zone_nr_lru_pages(), when retrieving memcg zone numbers for get_scan_count() for shrink_mem_cgroup_zone(): this is where a struct mem_cgroup is first accessed after being chosen by mem_cgroup_iter(). Just what protects a struct mem_cgroup from being freed, in between mem_cgroup_iter()'s css_get_next() and its css_tryget()? css_tryget() fails once css->refcnt is zero with CSS_REMOVED set in flags, yes: but what if that memory is freed and reused for something else, which sets "refcnt" non-zero? Hmm, and scope for an indefinite freeze if refcnt is left at zero but flags are cleared. It's tempting to move the css_tryget() into css_get_next(), to make it really "get" the css, but I don't think that actually solves anything: the same difficulty in moving from css_id found to stable css remains. But we already have rcu_read_lock() around the two, so it's easily fixed if __mem_cgroup_free() just uses kfree_rcu() to free mem_cgroup. However, a big struct mem_cgroup is allocated with vzalloc() instead of kzalloc(), and we're not allowed to vfree() at interrupt time: there doesn't appear to be a general vfree_rcu() to help with this, so roll our own using schedule_work(). The compiler decently removes vfree_work() and vfree_rcu() when the config doesn't need them.

b832796 Anton Blanchard 07 March 2012, 00:42:49 UTC perf tools: Incorrect use of snprintf results in SEGV I have a workload where perf top scribbles over the stack and we SEGV. What makes it interesting is that an snprintf is causing this. The workload is a c++ gem that has method names over 3000 characters long, but snprintf is designed to avoid overrunning buffers. So what went wrong? The problem is we assume snprintf returns the number of characters written: ret += repsep_snprintf(bf + ret, size - ret, "[%c] ", self->level); ... ret += repsep_snprintf(bf + ret, size - ret, "%s", self->ms.sym->name); Unfortunately this is not how snprintf works. snprintf returns the number of characters that would have been written if there was enough space. In the above case, if the first snprintf returns a value larger than size, we pass a negative size into the second snprintf and happily scribble over the stack. If you have 3000 character c++ methods thats a lot of stack to trample. This patch fixes repsep_snprintf by clamping the value at size - 1 which is the maximum snprintf can write before adding the NULL terminator. I get the sinking feeling that there are a lot of other uses of snprintf that have this same bug, we should audit them all.

The problem occured with the change to return -EBUSY from transport_generic_cmd_sequencer() -> transport_generic_allocate_tasks() failures, that broke iscsit_handle_scsi_cmd() checking for -EINVAL in order to invoke a non GOOD status response. This was manifesting itself as data corruption with legacy SPC-2 reservations, but also effects iscsi-target LUNs with SPC-3 persistent reservations.

ad09233 Matt Fleming 14 February 2012, 11:41:06 UTC tile: Use set_current_blocked() and block_sigmask() As described in e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.

8aa8a7c Stephane Eranian 13 March 2012, 15:51:02 UTC perf record: Fix buffer overrun bug in tracepoint_id_to_path() This patch fixes a buffer overrun bug in tracepoint_id_to_path(). The bug manisfested itself as a memory error reported by perf record. I ran into it with perf sched: $ perf sched rec noploop 2 noploop for 2 seconds [ perf record: Woken up 14 times to write data ] [ perf record: Captured and wrote 42.701 MB perf.data (~1865622 samples) ] Fatal: No memory to alloc tracepoints list It turned out that tracepoint_id_to_path() was reading the tracepoint id using read() but the buffer was not large enough to include the \n terminator for id with 4 digits or more. The patch fixes the problem by extending the buffer to a more reasonable size covering all possible id length include \n terminator. Note that atoll() stops at the first non digit character, thus it is not necessary to clear the buffer between each read.

But this will never happen for persistent device, because it's socket holds network namespace.

3780d03 Stanislaw Gruszka 09 March 2012, 11:39:54 UTC rt2x00: fix random stalls Is possible that we stop queue and then do not wake up it again, especially when packets are transmitted fast. That can be easily reproduced with modified tx queue entry_num to some small value e.g. 16. If mac80211 already hold local->queue_stop_reason_lock, then we can wait on that lock in both rt2x00queue_pause_queue() and rt2x00queue_unpause_queue(). After drooping ->queue_stop_reason_lock is possible that __ieee80211_wake_queue() will be performed before __ieee80211_stop_queue(), hence we stop queue and newer wake up it again. Another race condition is possible when between rt2x00queue_threshold() check and rt2x00queue_pause_queue() we will process all pending tx buffers on different cpu. This might happen if for example interrupt will be triggered on cpu performing rt2x00mac_tx(). To prevent race conditions serialize pause/unpause by queue->tx_lock.

Simon Kirby discovered a successful connection was delayed by 20 seconds before being responsive. In my tests, I discovered that xmit frames were lost, and needed ~4 retransmits and a socket dst rebuild before being really sent. In case of syncookie initiated connection, we use a different path to initialize the socket dst, and inet->cork.fl.u.ip4 is left cleared. As ip_queue_xmit() now depends on inet flow being setup, fix this by copying the temp flowi4 we use in cookie_v4_check().
