2015-11-16dm thin: restore requested 'error_if_no_space' setting on OODS to WRITE ↵Mike Snitzer
transition A thin-pool that is in out-of-data-space (OODS) mode may transition back to write mode -- without the admin adding more space to the thin-pool -- if/when blocks are released (either by deleting thin devices or discarding provisioned blocks). But as part of the thin-pool's earlier transition to out-of-data-space mode the thin-pool may have set the 'error_if_no_space' flag to true if the no_space_timeout expires without more space having been made available. That implementation detail, of changing the pool's error_if_no_space setting, needs to be reset back to the default that the user specified when the thin-pool's table was loaded. Otherwise we'll drop the user requested behaviour on the floor when this out-of-data-space to write mode transition occurs.

2015-11-16drm/i915: Fix GT frequency roundingMika Kuoppala
When we set and later readback a frequency value through sysfs interface, igt/pm_rpm assumes that we get same value back if it matches hw granularity. On bxt we have found out that this is not always the case. Currently frequency - hw ratio - frequency conversions round down, with few exceptions on platforms that have more specific conversions. On bxt the supported range can be for example from 100Mhz to 650Mhz. Midpoint is then calculated by test to be 375 which pm_rps uses to find a closest hw supported frequency. That is 366 (ratio 22), which it then writes back. But as the rounding down kicks in, driver actually sets 350 instead of 366, as 366 is 2/3 below 22 * 50/3. Fix this by rounding to closest instead of rounding down in freq-ratio-freq conversions.

2015-11-16ipmi watchdog : add panic_wdt_timeout parameterJean-Yves Faye
In order to allow panic actions to be processed, the ipmi watchdog driver sets a new timeout value on panic. The 255s timeout was designed to allow kdump and others actions on panic, as in http://lkml.iu.edu/hypermail/linux/kernel/0711.3/0258.html This is counter-intuitive for a end-user who sets watchdog timeout value to something like 30s and who expects BMC to reset the system within 30s of a panic.

In order to fix this issue, hold the spinlock, and copy all counter indices into a temporary array, and release the spinlock. Afterwards, iterate over this array and free every counter.

2015-11-15net/mlx5e: Max mtu comparison fixDoron Tsur
On change mtu the driver compares between hardware queried mtu and software requested mtu. We need to compare between software representation of the queried mtu and the requested mtu.

2015-11-15net/mlx5e: Added self loopback preventionTariq Toukan
Prevent outgoing multicast frames from looping back to the RX queue. By introducing new HW capability self_lb_en_modifiable, which indicates the support to modify self_lb_en bit in modify_tir command. When this capability is set we can prevent TIRs from sending back loopback multicast traffic to their own RQs, by "refreshing TIRs" with modify_tir command, on every time new channels (SQs/RQs) are created at device open. This is needed since TIRs are static and only allocated once on driver load, and the loopback decision is under their responsibility. Fixes issues of the kind: "IPv6: eth2: IPv6 duplicate address fe80::e61d:2dff:fe5c:f2e9 detected!" The issue is seen since the IPv6 solicitations multicast messages are loopedback and the network stack thinks they are coming from another host.

2015-11-15iwlwifi: mvm: don't overwrite the key indices in D3 entryLuca Coelho
When entering D3, we need to use hardcoded key indices because the firmware requires that. To do so, we are overwriting the HW key index in the keyconf structure, which makes it impossible to reuse the indices that were used before entering D3. Additionally, we overwrite all the non-PTK keys with index 1, because the firmware only allows one non-PTK key to be set. This is bad, because when we resume, we may try to set more than one key with index 1, which will obviously fail. To fix this, allow the callers to set a pre-defined index to use in iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from the keyconf struct (which requires overwriting it). In normal cases, the caller can pass STA_KEY_IDX_INVALID, which will cause a new key offset to be chosen. During HW_RESTART, we pass the offset that is in use. And during D3 entry, we pass the hardcoded indices we need to use. Additionally, don't clear the fw_key_table in D3 entry, so that the flags are still set with the pre-D3 values when exiting D3. fixes=I3165c22362483f0152d9ec1d2a987fb5529727c1 Fixes: b546dcd6b742 ("iwlwifi: mvm: don't reset key index on HW restart") Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
