In commit: 3078cde7 can: at91_can: add dt support device tree support was added to the at91_can driver. In this commit the mapping of device to driver data was mixed up. This results in the sam9x5 parameters being used for the sam9263 and the workaround for the broken mailbox 0 on the sam9263 not being activated. This patch fixes the broken platform_device_id table.

abort pending TX In patch 0d1862e can: flexcan: fix flexcan_chip_start() on imx6 the loop in flexcan_chip_start() that iterates over all mailboxes after the soft reset of the CAN core was removed. This loop put all mailboxes (even the ones marked as reserved 1...7) into EMPTY/INACTIVE mode. On mailboxes 8...63, this aborts any pending TX messages. After a cold boot there is random garbage in the mailboxes, which leads to spontaneous transmit of CAN frames during first activation. Further if the interface was disabled with a pending message (usually due to an error condition on the CAN bus), this message is retransmitted after enabling the interface again. This patch fixes the regression by: 1) Limiting the maximum number of used mailboxes to 8, 0...7 are used by the RX FIFO, 8 is used by TX. 2) Marking the TX mailbox as EMPTY/INACTIVE, so that any pending TX of that mailbox is aborted.

2013-10-09gianfar: Enable eTSEC-20 erratum w/a for P2020 Rev1Claudiu Manoil
Enable workaround for P2020/P2010 erratum eTSEC 20, "Excess delays when transmitting TOE=1 large frames". The impact is that frames lager than 2500-bytes for which TOE (i.e. TCP/IP hw accelerations like Tx csum) is enabled may see excess delay before start of transmission.

Use the macros and defines from mpc85xx.h to simplify and prevent errors in identifying a mpc85xx based SoC for errata detection. This should help enabling (and identifying) workarounds for various mpc85xx based chips and revisions. For instance, express MPC8548 Rev.2 as: (SVR_SOC_VER(svr) == SVR_8548) && (SVR_REV(svr) == 0x20) instead of: (pvr == 0x80210020 && mod == 0x8030 && rev == 0x0020) Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec Steffen Klassert says: ==================== 1) We used the wrong netlink attribute to verify the lenght of the replay window on async events. Fix this by using the right netlink attribute. 2) Policy lookups can not match the output interface on forwarding. Add the needed informations to the flow informations. 3) We update the pmtu when we receive a ICMPV6_DEST_UNREACH message on IPsec with ipv6. This is wrong and leads to strange fragmented packets, only ICMPV6_PKT_TOOBIG messages should update the pmtu. Fix this by removing the ICMPV6_DEST_UNREACH check from the IPsec protocol error handlers. 4) The legacy IPsec anti replay mechanism supports anti replay windows up to 32 packets. If a user requests for a bigger anti replay window, we use 32 packets but pretend that we use the requested window size. Fix from Fan Du. 5) If asynchronous events are enabled and replay_maxdiff is set to zero, we generate an async event for every received packet instead of checking whether a timeout occurred. Fix from Thomas Egerer. 6) Policies need a refcount when the state resolution timer is armed. Otherwise the timer can fire after the policy is deleted. 7) We might dreference a NULL pointer if the hold_queue is empty, add a check to avoid this. ==================== Signed-off-by: David S.

2013-10-09hwmon: (applesmc) Always read until end of dataHenrik Rydberg
The crash reported and investigated in commit 5f4513 turned out to be caused by a change to the read interface on newer (2012) SMCs. Tests by Chris show that simply reading the data valid line is enough for the problem to go away. Additional tests show that the newer SMCs no longer wait for the number of requested bytes, but start sending data right away. Apparently the number of bytes to read is no longer specified as before, but instead found out by reading until end of data. Failure to read until end of data confuses the state machine, which eventually causes the crash. As a remedy, assuming bit0 is the read valid line, make sure there is nothing more to read before leaving the read function. Tested to resolve the original problem, and runtested on MBA3,1, MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on machines before 2012.

2013-10-09mac80211: correctly close cancelled scansEmmanuel Grumbach
__ieee80211_scan_completed is called from a worker. This means that the following flow is possible. * driver calls ieee80211_scan_completed * mac80211 cancels the scan (that is already complete) * __ieee80211_scan_completed runs When scan_work will finally run, it will see that the scan hasn't been aborted and might even trigger another scan on another band. This leads to a situation where cfg80211's scan is not done and no further scan can be issued. Fix this by setting a new flag when a HW scan is being cancelled so that no other scan will be triggered.

2013-10-09target: Fix assignment of LUN in tracepointsRoland Dreier
The unpacked_lun field in the SCSI target tracepoints should be initialized with cmd->orig_fe_lun rather than cmd->se_lun->unpacked_lun for two reasons: - most importantly, if we are in the cmd_complete tracepoint returning a check condition due to no LUN found, cmd->se_lun will be NULL and we'll crash trying to dereference it. - also, in any case, cmd->se_lun->unpacked_lun is an internal index into the target's internal set of LUNs; cmd->orig_fe_lun is much more useful and interesting, since it's the value the initiator actually sent.
