2016-12-09hwmon: (coretemp) Simplify sibling managementThomas Gleixner
The coretemp driver provides a sysfs interface per physical core. If hyperthreading is enabled and one of the siblings goes offline the sysfs interface is removed and then immeditately created again for the sibling. The only difference of them is the target cpu for the rdmsr_on_cpu() in the sysfs show functions. It's way simpler to keep a cpumask of cpus which are active in a package and only remove the interface when the last sibling goes offline. Otherwise just move the target cpu for the sysfs show functions to the still online sibling. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (coretemp) Fixup target cpu for package when cpu is offlinedThomas Gleixner
When a CPU is offlined nothing checks whether it is the target CPU for the package temperature sysfs interface. As a consequence all future readouts of the package temperature return crap: 90000 which is Tjmax of that package. Check whether the outgoing CPU is the target for the package and assign it to some other still online CPU in the package. Protect the change against the rdmsr_on_cpu() in show_crit_alarm().

2016-11-25tipc: resolve connection flow control compatibility problemJon Paul Maloy
In commit 10724cc7bb78 ("tipc: redesign connection-level flow control") we replaced the previous message based flow control with one based on 1k blocks. In order to ensure backwards compatibility the mechanism falls back to using message as base unit when it senses that the peer doesn't support the new algorithm. The default flow control window, i.e., how many units can be sent before the sender blocks and waits for an acknowledge (aka advertisement) is 512. This was tested against the previous version, which uses an acknowledge frequency of on ack per 256 received message, and found to work fine. However, we missed the fact that versions older than Linux 3.15 use an acknowledge frequency of 512, which is exactly the limit where a 4.6+ sender will stop and wait for acknowledge. This would also work fine if it weren't for the fact that if the first sent message on a 4.6+ server side is an empty SYNACK, this one is also is counted as a sent message, while it is not counted as a received message on a legacy 3.15-receiver. This leads to the sender always being one step ahead of the receiver, a scenario causing the sender to block after 512 sent messages, while the receiver only has registered 511 read messages. Hence, the legacy receiver is not trigged to send an acknowledge, with a permanently blocked sender as result. We solve this deadlock by simply allowing the sender to send one more message before it blocks, i.e., by a making minimal change to the condition used for determining connection congestion.

2016-11-25tipc: improve sanity check for received domain recordsJon Paul Maloy
In commit 35c55c9877f8 ("tipc: add neighbor monitoring framework") we added a data area to the link monitor STATE messages under the assumption that previous versions did not use any such data area. For versions older than Linux 4.3 this assumption is not correct. In those version, all STATE messages sent out from a node inadvertently contain a 16 byte data area containing a string; -a leftover from previous RESET messages which were using this during the setup phase. This string serves no purpose in STATE messages, and should no be there. Unfortunately, this data area is delivered to the link monitor framework, where a sanity check catches that it is not a correct domain record, and drops it. It also issues a rate limited warning about the event. Since such events occur much more frequently than anticipated, we now choose to remove the warning in order to not fill the kernel log with useless contents. We also make the sanity check stricter, to further reduce the risk that such data is inavertently admitted. Signed-off-by: Jon Maloy <jon.maloy@ericsson.com> Signed-off-by: David S.

2016-11-25tipc: fix compatibility bug in link monitoringJon Paul Maloy
commit 817298102b0b ("tipc: fix link priority propagation") introduced a compatibility problem between TIPC versions newer than Linux 4.6 and those older than Linux 4.4. In versions later than 4.4, link STATE messages only contain a non-zero link priority value when the sender wants the receiver to change its priority. This has the effect that the receiver resets itself in order to apply the new priority. This works well, and is consistent with the said commit. However, in versions older than 4.4 a valid link priority is present in all sent link STATE messages, leading to cyclic link establishment and reset on the 4.6+ node. We fix this by adding a test that the received value should not only be valid, but also differ from the current value in order to cause the receiving link endpoint to reset.

Dave Anglin then looked again at the TLB related code and found two issues in the PCI DMA and generic TLB flush functions. Then, in our startup code we had some timing of the cache and TLB functions to calculate a threshold when to use a complete TLB/cache flush or just to flush a specific range. This code produced a race with newly started CPUs and thus lead to occasional kernel crashes (due to stale TLB/cache entries). The patch by Dave fixes this issue by flushing the local caches before starting secondary CPUs and by removing the race. The last problem fixed by this series is that we quite often suffered from hung tasks and self-detected stalls on the CPUs. It was somehow clear that this was related to the (in v4.7) newly introduced cr16 clocksource and the own implementation of sched_clock(). I replaced the open-coded sched_clock() function and switched to the generic sched_clock() implementation which seems to have fixed this isse as well.

2016-11-25MAINTAINERS: Add bug tracking system location entry typeRafael J. Wysocki
Following the kernel Bugzilla discussion during the Kernel Summit (https://lwn.net/Articles/705245/), add bug tracking system location entry type (B) to MAINTAINERS and populate it for several subsystems known to be using the kernel BZ actively (and add the upstream BZ for ACPICA too).

2016-11-25Revert "i2c: designware: do not disable adapter after transfer"Jarkko Nikula
This reverts commit 0317e6c0f1dc1ba86b8d9dccc010c5e77b8355fa. Srinivas reported recently touchscreen and touchpad stopped working in Haswell based machine in Linux 4.9-rc series with timeout errors from i2c_designware: [ 16.508013] i2c_designware INT33C3:00: controller timed out [ 16.508302] i2c_hid i2c-MSFT0001:02: failed to change power setting. [ 17.532016] i2c_designware INT33C3:00: controller timed out [ 18.556022] i2c_designware INT33C3:00: controller timed out [ 18.556315] i2c_hid i2c-ATML1000:00: failed to retrieve report from device. I managed to reproduce similar errors on another Haswell based machine where touchscreen initialization fails maybe in every 1/5 - 1/2 boots. Since root cause for these errors is not clear yet and debugging is ongoing it's better to revert this commit as we are near to release.
