Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for your net tree, they are rather small patches but fixing several outstanding bugs in nf_conntrack and nf_tables, as well as minor problems with missing SYNPROXY header uapi installation: 1) Oneliner not to leak conntrack kmemcache on module removal, this problem was introduced in the previous merge window, patch from Florian Westphal. 2) Two fixes for insufficient ruleset loop validation, one due to incorrect flag check in nf_tables_bind_set() and another related to silly wrong generation mask logic from the walk path, from Liping Zhang. 3) Fix double-free of anonymous sets on error, this fix simplifies the code to let the abort path take care of releasing the set object, also from Liping Zhang. 4) The introduction of helper function for transactions broke the skip inactive rules logic from the nft_do_chain(), again from Liping Zhang. 5) Two patches to install uapi xt_SYNPROXY.h header and calm down kbuild robot due to missing #include <linux/types.h>. ==================== Signed-off-by: David S.

2016-06-17IB/hfi1: Send a pkey change event on driver pkey updateSebastian Sanchez
Swapping a cable from a "Mgmt Allowed=No" switch port to a "Mgmt Allowed=Yes" switch port doesn't send a pkey change notification. Therefore, the link doesn't become active as the oib_utils layer uses an old pkey table cache. Fix by ensuring the pkey change notification is sent when the table is changed both explicitly by the FM and implicitly by the driver via a cable swap.

2016-06-17IB/hfi1: Remove FULL_MGMT_P_KEY from pkey table at link upSebastian Sanchez
FULL_MGMT_P_KEY doesn't get cleared from the pkey table at link bounce because the link down and link bounce code paths are different when moving a QSFP cable on a switch. This causes an HFI unit connected to a switch to try to be initialized to an FM node when the QSFP cable is moved from a MgmtAllowed=NO port to a MgmtAllowed=YES port and back to a MgmtAllowed=NO port. Remove FULL_MGMT_P_KEY from pkey table at link up.

The current value of 500us for the packet egress timeout is too small which causes the host to declare failure on draining packets too early and unnecessarily bounces the link.

2016-06-17IB/hfi1: Fix credit return threshold adjustmentJubin John
The credit return threshold adjustment on mtu change algorithm does not take into account all the kernel send contexts that are assigned per VL. Use the pio send context map to adjust the credit return thresholds for all the allocated and assigned kernel send contexts based on the MTU adjustment per VL. The pio send context map can be changed dynamically based on the actual number of operational vls which is set by the fabric manager. When this happens update the credit return threshold values for all the remapped kernel send contexts.

2016-06-17IB/cma: Make the code easier to verifyBart Van Assche
Static source code analysis tools like smatch cannot handle functions that lock or not lock a mutex depending on the value of the arguments. Hence inline the function cma_disable_callback(). Additionally, this patch realizes a small performance optimization by reducing the number of mutex_lock() and mutex_unlock() calls in the modified functions. With this patch applied smatch no longer complains about source file cma.c.

2016-06-17btrfs: avoid blocking open_ctree from cleaner_kthreadZygo Blaxell
This fixes a problem introduced in commit 2f3165ecf103599f82bf0ea254039db335fb5005 "btrfs: don't force mounts to wait for cleaner_kthread to delete one or more subvolumes". open_ctree eventually calls btrfs_replay_log which in turn calls btrfs_commit_super which tries to lock the cleaner_mutex, causing a recursive mutex deadlock during mount. Instead of playing whack-a-mole trying to keep up with all the functions that may want to lock cleaner_mutex, put all the cleaner_mutex lockers back where they were, and attack the problem more directly: keep cleaner_kthread asleep until the filesystem is mounted. When filesystems are mounted read-only and later remounted read-write, open_ctree did not set fs_info->open and neither does anything else. Set this flag in btrfs_remount so that neither btrfs_delete_unused_bgs nor cleaner_kthread get confused by the common case of "/" filesystem read-only mount followed by read-write remount.

2016-06-17btrfs: account for non-CoW'd blocks in btrfs_abort_transactionJeff Mahoney
The test for !trans->blocks_used in btrfs_abort_transaction is insufficient to determine whether it's safe to drop the transaction handle on the floor. btrfs_cow_block, informed by should_cow_block, can return blocks that have already been CoW'd in the current transaction. trans->blocks_used is only incremented for new block allocations. If an operation overlaps the blocks in the current transaction entirely and must abort the transaction, we'll happily let it clean up the trans handle even though it may have modified the blocks and will commit an incomplete operation. In the long-term, I'd like to do closer tracking of when the fs is actually modified so we can still recover as gracefully as possible, but that approach will need some discussion. In the short term, since this is the only code using trans->blocks_used, let's just switch it to a bool indicating whether any blocks were used and set it when should_cow_block returns false.

The interrupt 0 is not a valid interrupt number. In the event where the retrieval of the vbus-det gpio would return null, the gpiod_to_irq callback would return 0, while the current code makes the assumption that it is a valid interrupt, and would go on calling request_irq. Obviously, this would fail, preventing the driver from probing properly, while the vbus and id gpios are optional.

2016-06-17phy: rcar-gen3-usb2: fix unexpected repeat interrupts of VBUS changeYoshihiro Shimoda
This patch fixes an issue that the driver is possible to cause unexpected repeat interrupts if a board condition is wrong (e.g. even if the ID pin is as function, a board supplies the VBUS.) The reason why unexpected repeat interrupts happen is: 1) The driver changed the mode to function if it detected the ID pin is high and the VBUS is high. 2) After the driver changed function mode, it disabled the "VBUS control" feature. Then, the VBUS signal will be low. 3) Since the VBUS change interruption happened, the driver checked the ID pin and VBUS. 4) Since VBUS was low, the driver changed the mode to host and enabled the "VBUS control" feature. Then the VBUS signal will be high. 5) Since the VBUS change interruption happened, the driver did 1) above. So, this patch modified the condition in rcar_gen3_device_recognition() to check the ID pin only.

Because the return value is unmodified, the hdac regmap read/write functions should allow this value for the retry I/O operation, too.

2016-06-17regulator: anatop: allow regulator to be in bypass modeMika Båtsman
Bypass support was added in commit d38018f2019c ("regulator: anatop: Add bypass support to digital LDOs"). A check for valid voltage selectors was added in commit da0607c8df5c ("regulator: anatop: Fail on invalid voltage selector") but it also discards all regulators that are in bypass mode. Add check for the bypass setting. Errors below were seen on a Variscite mx6 board. anatop_regulator 20c8000.anatop:regulator-vddcore@140: Failed to read a valid default voltage selector. anatop_regulator: probe of 20c8000.anatop:regulator-vddcore@140 failed with error -22 anatop_regulator 20c8000.anatop:regulator-vddsoc@140: Failed to read a valid default voltage selector. anatop_regulator: probe of 20c8000.anatop:regulator-vddsoc@140 failed with error -22 Fixes: da0607c8df5c ("regulator: anatop: Fail on invalid voltage selector") Signed-off-by: Mika Båtsman <mbatsman@mvista.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-06-17ARM: dts: am437x-sk-evm: Reduce i2c0 bus speed for tps65218Dave Gerlach
Based on the latest timing specifications for the TPS65218 from the data sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206 from November 2014, we must change the i2c bus speed to better fit within the minimum high SCL time required for proper i2c transfer. When running at 400khz, measurements show that SCL spends 0.8125 uS/1.666 uS high/low which violates the requirement for minimum high period of SCL provided in datasheet Table 7.6 which is 1 uS. Switching to 100khz gives us 5 uS/5 uS high/low which both fall above the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low. Without this patch occasionally a voltage set operation from the kernel will appear to have worked but the actual voltage reflected on the PMIC will not have updated, causing problems especially with cpufreq that may update to a higher OPP without actually raising the voltage on DCDC2, leading to a hang.

2016-06-17powerpc/eeh: Fix invalid cached PE primary busGavin Shan
The PE primary bus cannot be got from its child devices when having full hotplug in error recovery. The PE primary bus is cached, which is done in commit <05ba75f84864> ("powerpc/eeh: Fix stale cached primary bus"). In eeh_reset_device(), the flag (EEH_PE_PRI_BUS) is cleared before the PCI hot remove. eeh_pe_bus_get() then returns NULL as the PE primary bus in pnv_eeh_reset() and it crashes the kernel eventually. This fixes the issue by clearing the flag (EEH_PE_PRI_BUS) before the PCI hot add. With it, the PowerNV EEH reset backend (pnv_eeh_reset()) can get valid PE primary bus through eeh_pe_bus_get().

2016-06-17powerpc/mm/hash: Don't add memory coherence if cache inhibited is setAneesh Kumar K.V
H_ENTER hcall handling in qemu had assumptions that a cache inhibited hpte entry won't have memory conference set. Also older kernel mentioned that some version of pHyp required this (the code removed by the below commit says: /* Make pHyp happy */ if ((rflags & _PAGE_NO_CACHE) && !(rflags & _PAGE_WRITETHRU)) hpte_r &= ~HPTE_R_M; But with older kernel we had some inconsistent memory conherence mapping. We always enabled memory conherence in the page fault path and removed memory conherence is _PAGE_NO_CACHE was set when we mapped the page via htab_bolt_mapping. The commit mentioned below tried to consolidate that by always enabling memory conherence. But as mentioned above that breaks Qemu H_ENTER handling. This patch update this such that we enable memory conherence only if cache inhibited is not set and bring fault handling, lpar and bolt mapping in sync.

2016-06-17ARM: OMAP2+: timer: add probe for clocksourcesTero Kristo
A few platforms are currently missing clocksource_probe() completely in their time_init functionality. On OMAP3430 for example, this is causing cpuidle to be pretty much dead, as the counter32k is not going to be registered and instead a gptimer is used as a clocksource. This will tick in periodic mode, preventing any deeper idle states. While here, also drop one unnecessary check for populated DT before existing clocksource_probe() call.
