2019-01-10tcp: change txhash on SYN-data timeoutYuchung Cheng1-1/+1
Previously upon SYN timeouts the sender recomputes the txhash to try a different path. However this does not apply on the initial timeout of SYN-data (active Fast Open). Therefore an active IPv6 Fast Open connection may incur one second RTO penalty to take on a new path after the second SYN retransmission uses a new flow label. This patch removes this undesirable behavior so Fast Open changes the flow label just like the regular connections. This also helps avoid falsely disabling Fast Open on the sender which triggers after two consecutive SYN timeouts on Fast Open.

2019-01-10CIFS: Fix credit computation for compounded requestsPavel Shilovsky1-18/+41
In SMB3 protocol every part of the compound chain consumes credits individually, so we need to call wait_for_free_credits() for each of the PDUs in the chain. If an operation is interrupted, we must ensure we return all credits taken from the server structure back. Without this patch server can sometimes disconnect the session due to credit mismatches, especially when first operation(s) are large writes.

Currently we reset the number of total credits granted by the server to 1 if the server didn't grant us anything int the response. This violates the SMB3 protocol - we need to trust the server and use the credit values from the response. Fix this by removing the corresponding code.

2019-01-10CIFS: Fix adjustment of credits for MTU requestsPavel Shilovsky1-2/+6
Currently for MTU requests we allocate maximum possible credits in advance and then adjust them according to the request size. While we were adjusting the number of credits belonging to the server, we were skipping adjustment of credits belonging to the request. This patch fixes it by setting request credits to CreditCharge field value of SMB2 packet header. Also ask 1 credit more for async read and write operations to increase parallelism and match the behavior of other operations.

2019-01-10arm64: kpti: Avoid rewriting early page tables when KASLR is enabledWill Deacon5-5/+52
A side effect of commit c55191e96caa ("arm64: mm: apply r/o permissions of VM areas to its linear alias as well") is that the linear map is created with page granularity, which means that transitioning the early page table from global to non-global mappings when enabling kpti can take a significant amount of time during boot. Given that most CPU implementations do not require kpti, this mainly impacts KASLR builds where kpti is forcefully enabled. However, in these situations we know early on that non-global mappings are required and can avoid the use of global mappings from the beginning. The only gotcha is Cavium erratum #27456, which we must detect based on the MIDR value of the boot CPU.

[BUG] Linux v5.0-rc1 will fail fstests/btrfs/163 with the following kernel message: BTRFS error (device dm-6): dev extent devid 1 physical offset 13631488 len 8388608 is beyond device boundary 0 BTRFS error (device dm-6): failed to verify dev extents against chunks: -117 BTRFS error (device dm-6): open_ctree failed [CAUSE] Commit cf90d884b347 ("btrfs: Introduce mount time chunk <-> dev extent mapping check") introduced strict check on dev extents. We use btrfs_find_device() with dev uuid and fs uuid set to NULL, and only dependent on @devid to find the real device. For seed devices, we call clone_fs_devices() in open_seed_devices() to allow us search seed devices directly. However clone_fs_devices() just populates devices with devid and dev uuid, without populating other essential members, like disk_total_bytes. This makes any device returned by btrfs_find_device(fs_info, devid, NULL, NULL) is just a dummy, with 0 disk_total_bytes, and any dev extents on the seed device will not pass the device boundary check. [FIX] This patch will try to verify the device returned by btrfs_find_device() and if it's a dummy then re-search in seed devices.

devm_kzalloc(), devm_kstrdup() and devm_kasprintf() all can fail internal allocation and return NULL. Using any of the assigned objects without checking is not safe. As this is early in the boot phase and these allocations really should not fail, any failure here is probably an indication of a more serious issue so it makes little sense to try and rollback the previous allocated resources or try to continue; but rather the probe function is simply exited with -ENOMEM.

2019-01-10ip: on queued skb use skb_header_pointer instead of pskb_may_pullWillem de Bruijn2-13/+9
Commit 2efd4fca703a ("ip: in cmsg IP(V6)_ORIGDSTADDR call pskb_may_pull") avoided a read beyond the end of the skb linear segment by calling pskb_may_pull. That function can trigger a BUG_ON in pskb_expand_head if the skb is shared, which it is when when peeking. It can also return ENOMEM. Avoid both by switching to safer skb_header_pointer.

Or else on subsequent attempts to bind the page tables into the ggtt, we will already believe that the vma has been pinned and continue on blithely.

2019-01-10mm/mmu_notifier: mm/rmap.c: Fix a mmu_notifier range bug in try_to_unmap_oneSean Christopherson1-2/+2
The conversion to use a structure for mmu_notifier_invalidate_range_*() unintentionally changed the usage in try_to_unmap_one() to init the 'struct mmu_notifier_range' with vma->vm_start instead of @address, i.e. it invalidates the wrong address range. Revert to the correct address range. Manifests as KVM use-after-free WARNINGs and subsequent "BUG: Bad page state in process X" errors when reclaiming from a KVM guest due to KVM removing the wrong pages from its own mappings.

2019-01-10PM-runtime: Fix autosuspend_delay on 32bits archVincent Guittot1-2/+2
Cast autosuspend_delay to u64 to make sure that the full computation of 'expires' or slack will be done in u64, even on 32bits arch. Otherwise, any delay greater than 2^31 nsec can overflow if signed 32bits is used when converting delay from msec to nsec.

2019-01-10rbd: don't return 0 on unmap if RBD_DEV_FLAG_REMOVING is setIlya Dryomov1-5/+4
There is a window between when RBD_DEV_FLAG_REMOVING is set and when the device is removed from rbd_dev_list. During this window, we set "already" and return 0. Returning 0 from write(2) can confuse userspace tools because 0 indicates that nothing was written. In particular, "rbd unmap" will retry the write multiple times a second: 10:28:05.463299 write(4, "0", 1) = 0 10:28:05.463509 write(4, "0", 1) = 0 10:28:05.463720 write(4, "0", 1) = 0 10:28:05.463942 write(4, "0", 1) = 0 10:28:05.464155 write(4, "0", 1) = 0 Cc: [email protected] Signed-off-by: Ilya Dryomov <[email protected]> Tested-by: Dongsheng Yang <[email protected]>
