* packet: Protect packet sk list with mutex (v2)Pavel Emelyanov2012-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change since v1: * Fixed inuse counters access spotted by Eric In patch eea68e2f (packet: Report socket mclist info via diag module) I've introduced a "scheduling in atomic" problem in packet diag module -- the socket list is traversed under rcu_read_lock() while performed under it sk mclist access requires rtnl lock (i.e. -- mutex) to be taken. [152363.820563] BUG: scheduling while atomic: crtools/12517/0x10000002 [152363.820573] 4 locks held by crtools/12517: [152363.820581] #0: (sock_diag_mutex){+.+.+.}, at: [<ffffffff81a2dcb5>] sock_diag_rcv+0x1f/0x3e [152363.820613] #1: (sock_diag_table_mutex){+.+.+.}, at: [<ffffffff81a2de70>] sock_diag_rcv_msg+0xdb/0x11a [152363.820644] #2: (nlk->cb_mutex){+.+.+.}, at: [<ffffffff81a67d01>] netlink_dump+0x23/0x1ab [152363.820693] #3: (rcu_read_lock){.+.+..}, at: [<ffffffff81b6a049>] packet_diag_dump+0x0/0x1af Similar thing was then re-introduced by further packet diag patches (fanount mutex and pgvec mutex for rings) :( Apart from being terribly sorry for the above, I propose to change the packet sk list protection from spinlock to mutex. This lock currently protects two modifications: * sklist * prot inuse counters The sklist modifications can be just reprotected with mutex since they already occur in a sleeping context. The inuse counters modifications are trickier -- the __this_cpu_-s are used inside, thus requiring the caller to handle the potential issues with contexts himself. Since packet sockets' counters are modified in two places only (packet_create and packet_release) we only need to protect the context from being preempted. BH disabling is not required in this case.

* mdio: translation of MMD EEE registers to/from ethtool settingsAllan, Bruce W2012-08-23
| | | | | | | | | | | | | | | | | | | | | The helper functions which translate IEEE MDIO Manageable Device (MMD) Energy-Efficient Ethernet (EEE) registers 3.20, 7.60 and 7.61 to and from the comparable ethtool supported/advertised settings will be needed by drivers other than those in PHYLIB (e.g. e1000e in a follow-on patch). In the same fashion as similar translation functions in linux/mii.h, move these functions from the PHYLIB core to the linux/mdio.h header file so the code will not have to be duplicated in each driver needing MMD-to-ethtool (and vice-versa) translations. The function and some variable names have been renamed to be more descriptive. Not tested on the only hardware that currently calls the related functions, stmmac, because I don't have access to any. Has been compile tested and the translations have been tested on a locally modified version of e1000e.

* net: remove delay at device dismantleEric Dumazet2012-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed extra one second delay in device dismantle, tracked down to a call to dst_dev_event() while some call_rcu() are still in RCU queues. These call_rcu() were posted by rt_free(struct rtable *rt) calls. We then wait a little (but one second) in netdev_wait_allrefs() before kicking again NETDEV_UNREGISTER. As the call_rcu() are now completed, dst_dev_event() can do the needed device swap on busy dst. To solve this problem, add a new NETDEV_UNREGISTER_FINAL, called after a rcu_barrier(), but outside of RTNL lock. Use NETDEV_UNREGISTER_FINAL with care ! Change dst_dev_event() handler to react to NETDEV_UNREGISTER_FINAL Also remove NETDEV_UNREGISTER_BATCH, as its not used anymore after IP cache removal.

They are: * Remove unnecessary RTNL locking now that we have support for namespace in nf_conntrack, from Patrick McHardy. * Cleanup to eliminate unnecessary goto in the initialization path of several Netfilter tables, from Jean Sacren. * Another cleanup from Wu Fengguang, this time to PTR_RET instead of if IS_ERR then return PTR_ERR. * Use list_for_each_entry_continue_rcu in nf_iterate, from Michael Wang. * Add pmtu_disc sysctl option to disable PMTU in their tunneling transmitter, from Julian Anastasov. * Generalize application protocol registration in IPVS and modify IPVS FTP helper to use it, from Julian Anastasov. * update Kconfig. The IPVS FTP helper depends on the Netfilter FTP helper for NAT support, from Julian Anastasov. * Add logic to update PMTU for IPIP packets in IPVS, again from Julian Anastasov. * A couple of sparse warning fixes for IPVS and Netfilter from Claudiu Ghioc and Patrick McHardy respectively.

Very broadly speaking this patch expands the concept. This patch introduces compact_checklock_irqsave() to check if a lock is contended or the process needs to be scheduled. If either condition is true then async compaction is aborted and the caller is informed. The page allocator will fail a THP allocation if compaction failed due to contention. This patch also introduces compact_trylock_irqsave() which will acquire the lock only if it is not contended and the process does not need to schedule.

The kernel passes all-zero SCM_CREDENTIALS ancillary data to the receiver if the sender did not provide such data, instead of not including any such data at all or including the correct data from the peer (as it is the case with AF_UNIX). This bug was introduced in commit 16e572626961 (af_unix: dont send SCM_CREDENTIALS by default) This patch forces passing credentials for netlink, as before the regression. Another fix would be to not add SCM_CREDENTIALS in netlink messages if not provided by the sender, but it might break some programs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Within SIP messages IPv6 addresses are enclosed in square brackets in most cases, with the exception of the "received=" header parameter. Currently the helper fails to parse enclosed addresses. This patch: - changes the SIP address parsing function to enforce square brackets when required, and accept them when not required but present, as recommended by RFC 5118. - adds a new SDP address parsing function that never accepts square brackets since SDP doesn't use them. With these changes, the SIP helper correctly parses all test messages from RFC 5118 (Session Initiation Protocol (SIP) Torture Test Messages for Internet Protocol Version 6 (IPv6)).

It is thus read again on one of the sockets of the fanout group. This result in a loop for software which generate packets when receiving one. This retransmission is not the intended behavior: a fanout group must behave like a single socket. The packet should not be transmitted on a socket if it originates from a socket belonging to the same fanout group. This patch fixes the issue by changing the transmission check to take fanout group info account.

This also requires the introduction of helper function of_get_next_available_child(), which returns the next available child node.

However, this has revealed some problems running hackbench on SMP platforms due to the way in which the MUTEX_SPIN_ON_OWNER code operates. The symptoms are that a bunch of hackbench tasks are left waiting on an unlocked mutex and therefore never get woken up to claim it. This boils down to the following sequence of events: Task A Task B Task C Lock value 0 1 1 lock() 0 2 lock() 0 3 spin(A) 0 4 unlock() 1 5 lock() 0 6 cmpxchg(1,0) 0 7 contended() -1 8 lock() 0 9 spin(C) 0 10 unlock() 1 11 cmpxchg(1,0) 0 12 unlock() 1 At this point, the lock is unlocked, but Task B is in an uninterruptible sleep with nobody to wake it up. This patch fixes the problem by ensuring we put the lock into the contended state if we fail to acquire it on the fastpath, ensuring that any blocked waiters are woken up when the mutex is released.

Otherwise, when the root file system is mounted read-only, the journal is replayed, and the error indicator is transferred to the superblock --- but the s_errno field in the jbd2 superblock is left set (since although we cleared it in memory, we never flushed it out to disk). This can end up confusing e2fsck. We should make e2fsck more robust in this case, but the kernel shouldn't be leaving things in this confused state, either.
