serial: 8250: Add Quark X1000 to 8250_pci.c

2014-10-17T07:43:21Z

commit 1ede7dcca3c4fa15a518ab0473126f9c3e621e4c upstream. Quark X1000 contains two designware derived 8250 serial ports. Each port has a unique PCI configuration space consisting of BAR0:UART BAR1:DMA respectively. Unlike the standard 8250 the register width is 32 bits for RHR,IER etc The Quark UART has a fundamental clock @ 44.2368 MHz allowing for a bitrate of up to about 2.76 megabits per second. This patch enables standard 8250 mode Signed-off-by: Bryan O'Donoghue Reviewed-by: Heikki Krogerus Signed-off-by: Jiri Slaby

USB: Add device quirk for ASUS T100 Base Station keyboard

2014-10-17T07:43:19Z

commit ddbe1fca0bcb87ca8c199ea873a456ca8a948567 upstream. This full-speed USB device generates spurious remote wakeup event as soon as USB_DEVICE_REMOTE_WAKEUP feature is set. As the result, Linux can't enter system suspend and S0ix power saving modes once this keyboard is used. This patch tries to introduce USB_QUIRK_IGNORE_REMOTE_WAKEUP quirk. With this quirk set, wakeup capability will be ignored during device configure. This patch could be back-ported to kernels as old as 2.6.39.

tcp: fixing TLP's FIN recovery

2014-10-17T07:43:19Z

[ Upstream commit bef1909ee3ed1ca39231b260a8d3b4544ecd0c8f ] Fix to a problem observed when losing a FIN segment that does not contain data. In such situations, TLP is unable to recover from *any* tail loss and instead adds at least PTO ms to the retransmission process, i.e., RTO = RTO + PTO.

sctp: handle association restarts when the socket is closed.

2014-10-17T07:43:19Z

[ Upstream commit bdf6fa52f01b941d4a80372d56de465bdbbd1d23 ] Currently association restarts do not take into consideration the state of the socket. When a restart happens, the current assocation simply transitions into established state. This creates a condition where a remote system, through a the restart procedure, may create a local association that is no way reachable by user. The conditions to trigger this are as follows: 1) Remote does not acknoledge some data causing data to remain outstanding. 2) Local application calls close() on the socket. Since data is still outstanding, the association is placed in SHUTDOWN_PENDING state. However, the socket is closed. 3) The remote tries to create a new association, triggering a restart on the local system. The association moves from SHUTDOWN_PENDING to ESTABLISHED. At this point, it is no longer reachable by any socket on the local system. This patch addresses the above situation by moving the newly ESTABLISHED association into SHUTDOWN-SENT state and bundling a SHUTDOWN after the COOKIE-ACK chunk. This way, the restarted associate immidiately enters the shutdown procedure and forces the termination of the unreachable association.

team: avoid race condition in scheduling delayed work

2014-10-17T07:43:18Z

[ Upstream commit 47549650abd13d873fd2e5fc218db19e21031074 ] When team_notify_peers and team_mcast_rejoin are called, they both reset their respective .count_pending atomic variable. Then when the actual worker function is executed, the variable is atomically decremented. This pattern introduces a potential race condition where the .count_pending rolls over and the worker function keeps rescheduling until .count_pending decrements to zero again: THREAD 1 THREAD 2 ======== ======== team_notify_peers(teamX) atomic_set count_pending = 1 schedule_delayed_work team_notify_peers(teamX) atomic_set count_pending = 1 team_notify_peers_work atomic_dec_and_test count_pending = 0 (return) schedule_delayed_work team_notify_peers_work atomic_dec_and_test count_pending = -1 schedule_delayed_work (repeat until count_pending = 0) Instead of assigning a new value to .count_pending, use atomic_add to tack-on the additional desired worker function invocations.
