2010-09-09ahci: fix hang on failed softresetTejun Heo1-1/+1
ahci_do_softreset() compared the current time and deadline in reverse when calculating timeout for SRST issue. The result is that if @deadline is in future, SRST is issued with 0 timeout, which hasn't caused any problem because it later waits for DRDY with the correct timeout. If deadline is already exceeded by the time SRST is about to be issued, the timeout calculation underflows and if the device doesn't respond, timeout doesn't trigger for a _very_ long time. Reverse the incorrect comparison order.

2010-09-09KVM: x86: Perform hardware_enable in CPU_STARTING callbackZachary Amsden1-3/+2
The CPU_STARTING callback was added upstream with the intention of being used for KVM, specifically for the hardware enablement that must be done before we can run in hardware virt. It had bugs on the x86_64 architecture at the time, where it was called after CPU_ONLINE. The arches have since merged and the bug is gone. It might be noted other features should probably start making use of this callback; microcode updates in particular which might be fixing important erratums would be best applied before beginning to run user tasks.

2010-09-09lglock: make lg_lock_global() actually lock globallyJonathan Corbet1-2/+2
lg_lock_global() currently only acquires spinlocks for online CPUs, but it's meant to lock all possible CPUs. Lglock-protected resources may be associated with removed CPUs - and, indeed, that could happen with the per-superblock open files lists. At Nick's suggestion, change for_each_online_cpu() to for_each_possible_cpu() to protect accesses to those resources.

2010-09-09dquot: do full inode dirty in allocating spaceShaohua Li1-2/+8
Alex Shi found a regression when doing ffsb test. The test has several threads, and each thread creates a small file, write to it and then delete it. ffsb reports about 20% regression and Alex bisected it to 43d2932d88e4. The test will call __mark_inode_dirty 3 times. without this commit, we only take inode_lock one time, while with it, we take the lock 3 times with flags ( I_DIRTY_SYNC,I_DIRTY_PAGES,I_DIRTY). Perf shows the lock contention increased too much. Below proposed patch fixes it. fs is allocating blocks, which usually means file writes and the inode will be dirtied soon. We fully dirty the inode to reduce some inode_lock contention in several calls of __mark_inode_dirty. Jan Kara: Added comment.

2010-09-08udp: add rehash on connect()Eric Dumazet6-2/+66
commit 30fff923 introduced in linux-2.6.33 (udp: bind() optimisation) added a secondary hash on UDP, hashed on (local addr, local port). Problem is that following sequence : fd = socket(...) connect(fd, &remote, ...) not only selects remote end point (address and port), but also sets local address, while UDP stack stored in secondary hash table the socket while its local address was INADDR_ANY (or ipv6 equivalent) Sequence is : - autobind() : choose a random local port, insert socket in hash tables [while local address is INADDR_ANY] - connect() : set remote address and port, change local address to IP given by a route lookup. When an incoming UDP frame comes, if more than 10 sockets are found in primary hash table, we switch to secondary table, and fail to find socket because its local address changed. One solution to this problem is to rehash datagram socket if needed. We add a new rehash(struct socket *) method in "struct proto", and implement this method for UDP v4 & v6, using a common helper. This rehashing only takes care of secondary hash table, since primary hash (based on local port only) is not changed.

2010-09-09PM: Prevent waiting forever on asynchronous resume after failing suspendColin Cross1-0/+1
During suspend, the power.completion is expected to be set when a device has not yet started suspending. Set it on init to fix a corner case where a device is resumed when its parent has never suspended. Consider three drivers, A, B, and C. The parent of A is C, and C has async_suspend set. On boot, C->power.completion is initialized to 0. During the first suspend: suspend_devices_and_enter(...) dpm_resume(...) device_suspend(A) device_suspend(B) returns error, aborts suspend dpm_resume_end(...) dpm_resume(...) device_resume(A) dpm_wait(A->parent == C) wait_for_completion(C->power.completion) The wait_for_completion will never complete, because complete_all(C->power.completion) will only be called from device_suspend(C) or device_resume(C), neither of which is called if suspend is aborted before C. After a successful suspend->resume cycle, where B doesn't abort suspend, C->power.completion is left in the completed state by the call to device_resume(C), and the same call path will work if B aborts suspend.

2010-09-08RDMA/nes: Fix double CLOSE event indication crashFaisal Latif1-8/+10
During a stress testing in a large cluster, multiple close event are detected and BUG() is hit in the iWARP core. The cause is that the active node gave up while waiting for an MPA response from the peer and tried to close the connection by sending RST. The passive node driver receives the RST but is waiting for MPA response from the user. When the MPA accept is received, the driver offloads the connection and sends a CLOSE event. The driver gets an AE indicating RESET received and also sends a CLOSE event, hitting a BUG(). Fix this by correcting RESET handling and sending CLOSE events.

2010-09-08cifs: prevent possible memory corruption in cifs_demultiplex_threadJeff Layton3-11/+17
cifs_demultiplex_thread sets the addr.sockAddr.sin_port without any regard for the socket family. While it may be that the error in question here never occurs on an IPv6 socket, it's probably best to be safe and set the port properly if it ever does. Break the port setting code out of cifs_fill_sockaddr and into a new function, and call that from cifs_demultiplex_thread.

2010-09-08cifs: eliminate some more premature cifsd exitsJeff Layton1-29/+12
If the tcpStatus is still CifsNew, the main cifs_demultiplex_loop can break out prematurely in some cases. This is wrong as we will almost always have other structures with pointers to the TCP_Server_Info. If the main loop breaks under any other condition other than tcpStatus == CifsExiting, then it'll face a use-after-free situation. I don't see any reason to treat a CifsNew tcpStatus differently than CifsGood. I believe we'll still want to attempt to reconnect in either case. What should happen in those situations is that the MIDs get marked as MID_RETRY_NEEDED. This will make CIFSSMBNegotiate return -EAGAIN, and then the caller can retry the whole thing on a newly reconnected socket. If that fails again in the same way, the caller of cifs_get_smb_ses should tear down the TCP_Server_Info struct.

2010-09-08cifs: prevent cifsd from exiting prematurelyJeff Layton1-9/+7
When cifs_demultiplex_thread exits, it does a number of cleanup tasks including freeing the TCP_Server_Info struct. Much of the existing code in cifs assumes that when there is a cisfSesInfo struct, that it holds a reference to a valid TCP_Server_Info struct. We can never allow cifsd to exit when a cifsSesInfo struct is still holding a reference to the server. The server pointers will then point to freed memory. This patch eliminates a couple of questionable conditions where it does this. The idea here is to make an -EINTR return from kernel_recvmsg behave the same way as -ERESTARTSYS or -EAGAIN. If the task was signalled from cifs_put_tcp_session, then tcpStatus will be CifsExiting, and the kernel_recvmsg call will return quickly. There's also another condition where this can occur too -- if the tcpStatus is still in CifsNew, then it will also exit if the server closes the socket prematurely. I think we'll probably also need to fix that situation, but that requires a bit more consideration. Signed-off-by: Jeff Layton <[email protected]> Signed-off-by: Steve French <[email protected]>

niu_get_ethtool_tcam_all() assumes that its output buffer is the right size, and warns before returning if it is not. However, the output buffer size is under user control and ETHTOOL_GRXCLSRLALL is an unprivileged ethtool command. Therefore this is at least a local denial-of-service vulnerability. Change it to check before writing each entry and to return an error if the buffer is already full. Compile-tested only. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S.

2010-09-08spi/pl022: fix APB pclk power regression on U300Linus Walleij1-6/+8
With the introduction of an AMBA PrimeCell per-cell block clock, the pclk was left on after probe() unless explicitly disabled. This clock is wired to the same clock on PL022 causing it to stay always on since. Fix this up properly by clocking the pclk whenever we want to write into any PL022 registers and clocking the external clock whenever we want to transmit messages on the bus.

2010-09-08spi/spi_s3c64xx: Warn if PIO transfers time outMark Brown1-0/+6
When using PIO we have a timeout for the TX and RX FIFOs to ensure that the data actually gets transferred. Warn if we hit that timeout - it should never happen, but this makes sure we'll find out if it does.
