Currently, we unconditionally make page table dirty in touch_pmd(). It may result in false-positive can_follow_write_pmd(). We may avoid the situation, if we would only make the page table entry dirty if caller asks for write access -- FOLL_WRITE. The patch also changes touch_pud() in the same way. Signed-off-by:

An independent security researcher, Mohamed Ghannam, has reported this vulnerability to Beyond Security's SecuriTeam Secure Disclosure program. The xfrm_dump_policy_done function expects xfrm_dump_policy to have been called at least once or it will crash. This can be triggered if a dump fails because the target socket's receive buffer is full. This patch fixes it by using the cb->start mechanism to ensure that the initialisation is always done regardless of the buffer situation.

BugLink: http://bugs.launchpad.net/bugs/1729256 xfs_attr3_root_inactive() walks the attr fork tree to invalidate the associated blocks. xfs_attr3_node_inactive() recursively descends from internal blocks to leaf blocks, caching block address values along the way to revisit parent blocks, locate the next entry and descend down that branch of the tree. The code that attempts to reread the parent block is unsafe because it assumes that the local xfs_da_node_entry pointer remains valid after an xfs_trans_brelse() and re-read of the parent buffer. Under heavy memory pressure, it is possible that the buffer has been reclaimed and reallocated by the time the parent block is reread. This means that 'btree' can point to an invalid memory address, lead to a random/garbage value for child_fsb and cause the subsequent read of the attr fork to go off the rails and return a NULL buffer for an attr fork offset that is most likely not allocated. Note that this problem can be manufactured by setting XFS_ATTR_BTREE_REF to 0 to prevent LRU caching of attr buffers, creating a file with a multi-level attr fork and removing it to trigger inactivation. To address this problem, reinit the node/btree pointers to the parent buffer after it has been re-read. This ensures btree points to a valid record and allows the walk to proceed. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1729637 In commit 242d3a49 ("ipv6: reorder ip6_route_dev_notifier after ipv6_dev_notf") I assumed NETDEV_REGISTER and NETDEV_UNREGISTER are paired, unfortunately, as reported by jeffy, netdev_wait_allrefs() could rebroadcast NETDEV_UNREGISTER event until all refs are gone. We have to add an additional check to avoid this corner case. For netdev_wait_allrefs() dev->reg_state is NETREG_UNREGISTERED, for dev_change_net_namespace(), dev->reg_state is NETREG_REGISTERED. So check for dev->reg_state != NETREG_UNREGISTERED. Fixes: 242d3a49 ("ipv6: reorder ip6_route_dev_notifier after ipv6_dev_notf") Reported-by:

BugLink: http://bugs.launchpad.net/bugs/1727331 POWER8 has one virtual timebase (VTB) register per subcore, not one per CPU thread. The HV KVM code currently treats VTB as a per-thread register, which can lead to spurious soft lockup messages from guests which use the VTB as the time source for the soft lockup detector. (CPUs before POWER8 did not have the VTB register.) For HV KVM, this fixes the problem by making only the primary thread in each virtual core save and restore the VTB value. With this, the VTB state becomes part of the kvmppc_vcore structure. This also means that "piggybacking" of multiple virtual cores onto one subcore is not possible on POWER8, because then the virtual cores would share a single VTB register. PR KVM emulates a VTB register, which is per-vcpu because PR KVM has no notion of CPU threads or SMT. For PR KVM we move the VTB state into the kvmppc_vcpu_book3s struct.

BugLink: http://bugs.launchpad.net/bugs/1732698 commit 1b1fe542 upstream. Now that we've added a 'trigger_async_request' knob to test the request_firmware_nowait() API, let's use it. Also add tests for the empty ("") string, since there have been a couple errors in that handling already. Since we now have real ways that the sysfs write might fail, let's add the appropriate check on the 'echo' lines too. Signed-off-by:
