Add new Common Code routines to retrieve Firmware Device Log parameters from PCIE_FW_PF[7]. The firmware initializes its Device Log very early on and stores the parameters for its location/size in that register. Using the parameters from the register allows us to access the Firmware Device Log even when the firmware crashes very early on or we're not attached to the firmware Based on original work by Casey Leedom <[email protected]> Signed-off-by: Hariprasad Shenai <[email protected]> Signed-off-by: David S.

When IOMM-vtd is active, once main kernel crashes unfinished DMAE transactions will be blocked, putting the HW in an error state which will cause further transactions to timeout. Current employed logic uses wrong macros, causing the first function to be the only function that cleanups that error state during its probe/load.

2015-04-01bnx2x: Fix kdump on 4-port deviceYuval Mintz1-18/+35
When running in a kdump kernel, it's very likely that due to sync. loss with management firmware the first PCI function to probe and reach the previous unload flow would decide it can reset the chip and continue onward. While doing so, it will only close its own Rx port. On a 4-port device where 2nd port on engine is a 1g-port, the 2nd port would allow ingress traffic after the chip is reset [assuming it was active on the first kernel]. This would later cause a HW attention. This changes driver flow to close both ports' 1g capabilities during the previous driver unload flow prior to the chip reset.

2015-04-01mac80211: fix RX A-MPDU session reorder timer deletionJohannes Berg3-5/+12
There's an issue with the way the RX A-MPDU reorder timer is deleted that can cause a kernel crash like this: * tid_rx is removed - call_rcu(ieee80211_free_tid_rx) * station is destroyed * reorder timer fires before ieee80211_free_tid_rx() runs, accessing the station, thus potentially crashing due to the use-after-free The station deletion is protected by synchronize_net(), but that isn't enough -- ieee80211_free_tid_rx() need not have run when that returns (it deletes the timer.) We could use rcu_barrier() instead of synchronize_net(), but that's much more expensive. Instead, to fix this, add a field tracking that the session is being deleted. In this case, the only re-arming of the timer happens with the reorder spinlock held, so make that code not rearm it if the session is being deleted and also delete the timer after setting that field. This ensures the timer cannot fire after ___ieee80211_stop_rx_ba_session() returns, which fixes the problem. Cc: [email protected] Signed-off-by: Johannes Berg <[email protected]>
2015-04-01x86/reboot: Add ASRock Q1900DC-ITX mainboard reboot quirkStefan Lippers-Hollmann1-0/+10
The ASRock Q1900DC-ITX mainboard (Baytrail-D) hangs randomly in both BIOS and UEFI mode while rebooting unless reboot=pci is used. Add a quirk to reboot via the pci method. The problem is very intermittent and hard to debug, it might succeed rebooting just fine 40 times in a row - but fails half a dozen times the next day. It seems to be slightly less common in BIOS CSM mode than native UEFI (with the CSM disabled), but it does happen in either mode. Since I've started testing this patch in late january, rebooting has been 100% reliable. Most of the time it already hangs during POST, but occasionally it might even make it through the bootloader and the kernel might even start booting, but then hangs before the mode switch. The same symptoms occur with grub-efi, gummiboot and grub-pc, just as well as (at least) kernel 3.16-3.19 and 4.0-rc6 (I haven't tried older kernels than 3.16). Upgrading to the most current mainboard firmware of the ASRock Q1900DC-ITX, version 1.20, does not improve the situation. ( Searching the web seems to suggest that other Bay Trail-D mainboards might be affected as well. ) -- Signed-off-by: Stefan Lippers-Hollmann <[email protected]> Cc: <[email protected]> Cc: Matt Fleming <[email protected]> Link: http://lkml.kernel.org/r/20150330224427.0fb58e42@mir Signed-off-by: Ingo Molnar <[email protected]>

2015-03-31sunrpc: make debugfs file creation failure non-fatalJeff Layton5-47/+41
We currently have a problem that SELinux policy is being enforced when creating debugfs files. If a debugfs file is created as a side effect of doing some syscall, then that creation can fail if the SELinux policy for that process prevents it. This seems wrong. We don't do that for files under /proc, for instance, so Bruce has proposed a patch to fix that. While discussing that patch however, Greg K.H. stated: "No kernel code should care / fail if a debugfs function fails, so please fix up the sunrpc code first." This patch converts all of the sunrpc debugfs setup code to be void return functins, and the callers to not look for errors from those functions. This should allow rpc_clnt and rpc_xprt creation to work, even if the kernel fails to create debugfs files for some reason. Symptoms were failing krb5 mounts on systems using gss-proxy and selinux.

Before commit 3900f29021f0bc7fe9815aa32f1a993b7dfdd402 ("bonding: slight optimizztion for bond_slave_override()") the override logic was to send packets with non-zero queue_id through the slave with corresponding queue_id, under two conditions only - if the slave can transmit and it's up. The above mentioned commit changed this logic by introducing an additional condition - whether the bond is active (indirectly, using the slave_can_tx and later - bond_is_active_slave), that prevents the user from implementing more complex policies according to the Documentation/networking/bonding.txt.

Similarly, when an address is added while the interface is down, it is added second time once the interface is brought up. When the interface is down, the addresses should be kept off the hash list for performance reasons. Ensure this is true, which also fixes the double add problem.

2015-03-31block: fix blk_stack_limits() regression due to lcm() changeMike Snitzer3-3/+15
Linux 3.19 commit 69c953c ("lib/lcm.c: lcm(n,0)=lcm(0,n) is 0, not n") caused blk_stack_limits() to not properly stack queue_limits for stacked devices (e.g. DM). Fix this regression by establishing lcm_not_zero() and switching blk_stack_limits() over to using it. DM uses blk_set_stacking_limits() to establish the initial top-level queue_limits that are then built up based on underlying devices' limits using blk_stack_limits(). In the case of optimal_io_size (io_opt) blk_set_stacking_limits() establishes a default value of 0. With commit 69c953c, lcm(0, n) is no longer n, which compromises proper stacking of the underlying devices' io_opt.

2015-03-31spi: pxa2xx: missing break in pxa2xx_ssp_get_clk_div()Dan Carpenter1-0/+2
We refactored this code but accidentally left out a break statement so QUARK_X1000_SSP isn't handled correctly.

2015-03-31spi: fsl-dspi: Fix clock rate scale valuesAaron Brice1-14/+21
Previous algorithm had an outer loop with the values {2,3,5,7} and an inner loop with {2,4,6,8,16,32,...,32768}, and would pick the first value over the required scaling value (where the total scale was the two numbers multiplied). Since the inner loop went up to 32768 it would always pick a value of 2 for PBR and a much higher than necessary value for BR. The desired scale factor was being divided by two I believe to compensate for the much higher scale factors (the divide by two not specified in the reference manual). Updated to check all values and find the smallest scale factor possible without going over the desired clock rate.
