2020-10-08vdpa/mlx5: Fix dependency on MLX5_COREEli Cohen
Remove propmt for selecting MLX5_VDPA by the user and modify MLX5_VDPA_NET to select MLX5_VDPA. Also modify MLX5_VDPA_NET to depend on mlx5_core. This fixes an issue where configuration sets 'y' for MLX5_VDPA_NET while MLX5_CORE is compiled as a module causing link errors.

2020-10-08r8169: consider that PHY reset may still be in progress after applying firmwareHeiner Kallweit
Some firmware files trigger a PHY soft reset and don't wait for it to be finished. PHY register writes directly after applying the firmware may fail or provide unexpected results therefore. Fix this by waiting for bit BMCR_RESET to be cleared after applying firmware. There's nothing wrong with the referenced change, it's just that the fix will apply cleanly only after this change.

2020-10-08openvswitch: handle DNAT tuple collisionDumitru Ceara
With multiple DNAT rules it's possible that after destination translation the resulting tuples collide. For example, two openvswitch flows: nw_dst=10.0.0.10,tp_dst=10, actions=ct(commit,table=2,nat(dst=20.0.0.1:20)) nw_dst=10.0.0.20,tp_dst=10, actions=ct(commit,table=2,nat(dst=20.0.0.1:20)) Assuming two TCP clients initiating the following connections: 10.0.0.10:5000->10.0.0.10:10 10.0.0.10:5000->10.0.0.20:10 Both tuples would translate to 10.0.0.10:5000->20.0.0.1:20 causing nf_conntrack_confirm() to fail because of tuple collision. Netfilter handles this case by allocating a null binding for SNAT at egress by default. Perform the same operation in openvswitch for DNAT if no explicit SNAT is requested by the user and allocate a null binding for SNAT for packets in the "original" direction.

2020-10-08afs: Fix deadlock between writeback and truncateDavid Howells
The afs filesystem has a lock[*] that it uses to serialise I/O operations going to the server (vnode->io_lock), as the server will only perform one modification operation at a time on any given file or directory. This prevents the the filesystem from filling up all the call slots to a server with calls that aren't going to be executed in parallel anyway, thereby allowing operations on other files to obtain slots. [*] Note that is probably redundant for directories at least since i_rwsem is used to serialise directory modifications and lookup/reading vs modification. The server does allow parallel non-modification ops, however. When a file truncation op completes, we truncate the in-memory copy of the file to match - but we do it whilst still holding the io_lock, the idea being to prevent races with other operations. However, if writeback starts in a worker thread simultaneously with truncation (whilst notify_change() is called with i_rwsem locked, writeback pays it no heed), it may manage to set PG_writeback bits on the pages that will get truncated before afs_setattr_success() manages to call truncate_pagecache(). Truncate will then wait for those pages - whilst still inside io_lock: # cat /proc/8837/stack [<0>] wait_on_page_bit_common+0x184/0x1e7 [<0>] truncate_inode_pages_range+0x37f/0x3eb [<0>] truncate_pagecache+0x3c/0x53 [<0>] afs_setattr_success+0x4d/0x6e [<0>] afs_wait_for_operation+0xd8/0x169 [<0>] afs_do_sync_operation+0x16/0x1f [<0>] afs_setattr+0x1fb/0x25d [<0>] notify_change+0x2cf/0x3c4 [<0>] do_truncate+0x7f/0xb2 [<0>] do_sys_ftruncate+0xd1/0x104 [<0>] do_syscall_64+0x2d/0x3a [<0>] entry_SYSCALL_64_after_hwframe+0x44/0xa9 The writeback operation, however, stalls indefinitely because it needs to get the io_lock to proceed: # cat /proc/5940/stack [<0>] afs_get_io_locks+0x58/0x1ae [<0>] afs_begin_vnode_operation+0xc7/0xd1 [<0>] afs_store_data+0x1b2/0x2a3 [<0>] afs_write_back_from_locked_page+0x418/0x57c [<0>] afs_writepages_region+0x196/0x224 [<0>] afs_writepages+0x74/0x156 [<0>] do_writepages+0x2d/0x56 [<0>] __writeback_single_inode+0x84/0x207 [<0>] writeback_sb_inodes+0x238/0x3cf [<0>] __writeback_inodes_wb+0x68/0x9f [<0>] wb_writeback+0x145/0x26c [<0>] wb_do_writeback+0x16a/0x194 [<0>] wb_workfn+0x74/0x177 [<0>] process_one_work+0x174/0x264 [<0>] worker_thread+0x117/0x1b9 [<0>] kthread+0xec/0xf1 [<0>] ret_from_fork+0x1f/0x30 and thus deadlock has occurred. Note that whilst afs_setattr() calls filemap_write_and_wait(), the fact that the caller is holding i_rwsem doesn't preclude more pages being dirtied through an mmap'd region. Fix this by: (1) Use the vnode validate_lock to mediate access between afs_setattr() and afs_writepages(): (a) Exclusively lock validate_lock in afs_setattr() around the whole RPC operation. (b) If WB_SYNC_ALL isn't set on entry to afs_writepages(), trying to shared-lock validate_lock and returning immediately if we couldn't get it. (c) If WB_SYNC_ALL is set, wait for the lock. The validate_lock is also used to validate a file and to zap its cache if the file was altered by a third party, so it's probably a good fit for this. (2) Move the truncation outside of the io_lock in setattr, using the same hook as is used for local directory editing. This requires the old i_size to be retained in the operation record as we commit the revised status to the inode members inside the io_lock still, but we still need to know if we reduced the file size.

2020-10-08iwlwifi: fix sar geo table initializationNaftali Goldstein
When adding support for version 3 of the GEO_TX_POWER_LIMIT command, the table argument of iwl_sar_geo_init was changed from a pointer a 1d array of now-removed iwl_per_chain_offset_group_v1 to a pointer to a 2d array of iwl_per_chain_offset (iwl_per_chain_offset_group_v1 was a struct containing 2 copies of iwl_per_chain_offset). So even for version 2 where the second dimension is of length 2, which means that the underlying memory layout of the array didn't change, this requires a small change in the way we loop over it, and this was missed. Additionally, for the case of version 3 where the second dimension is now 3, in order to fill the first two elements of each row correctly (lb and hb), iwl_sar_geo_init must get the true number of bands supported. But because we don't yet store any values for the 3rd (uhb) band, skip that band.

2020-10-08mm: avoid early COW write protect games during fork()Linus Torvalds
In commit 70e806e4e645 ("mm: Do early cow for pinned pages during fork() for ptes") we write-protected the PTE before doing the page pinning check, in order to avoid a race with concurrent fast-GUP pinning (which doesn't take the mm semaphore or the page table lock). That trick doesn't actually work - it doesn't handle memory ordering properly, and doing so would be prohibitively expensive. It also isn't really needed. While we're moving in the direction of allowing and supporting page pinning without marking the pinned area with MADV_DONTFORK, the fact is that we've never really supported this kind of odd "concurrent fork() and page pinning", and doing the serialization on a pte level is just wrong. We can add serialization with a per-mm sequence counter, so we know how to solve that race properly, but we'll do that at a more appropriate time. Right now this just removes the write protect games. It also turns out that the write protect games actually break on Power, as reported by Aneesh Kumar: "Architecture like ppc64 expects set_pte_at to be not used for updating a valid pte. This is further explained in commit 56eecdb912b5 ("mm: Use ptep/pmdp_set_numa() for updating _PAGE_NUMA bit")" and the code triggered a warning there: WARNING: CPU: 0 PID: 30613 at arch/powerpc/mm/pgtable.c:185 set_pte_at+0x2a8/0x3a0 arch/powerpc/mm/pgtable.c:185 Call Trace: copy_present_page mm/memory.c:857 [inline] copy_present_pte mm/memory.c:899 [inline] copy_pte_range mm/memory.c:1014 [inline] copy_pmd_range mm/memory.c:1092 [inline] copy_pud_range mm/memory.c:1127 [inline] copy_p4d_range mm/memory.c:1150 [inline] copy_page_range+0x1f6c/0x2cc0 mm/memory.c:1212 dup_mmap kernel/fork.c:592 [inline] dup_mm+0x77c/0xab0 kernel/fork.c:1355 copy_mm kernel/fork.c:1411 [inline] copy_process+0x1f00/0x2740 kernel/fork.c:2070 _do_fork+0xc4/0x10b0 kernel/fork.c:2429 Link: https://lore.kernel.org/lkml/CAHk-=wiWr+gO0Ro4LvnJBMs90OiePNyrE3E+pJvc9PzdBShdmw@mail.gmail.com/ Link: https://lore.kernel.org/linuxppc-dev/20201008092541.398079-1-aneesh.kumar@linux.ibm.com/ Reported-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> Tested-by: Leon Romanovsky <leonro@nvidia.com> Cc: Peter Xu <peterx@redhat.com> Cc: Jason Gunthorpe <jgg@ziepe.ca> Cc: John Hubbard <jhubbard@nvidia.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Jan Kara <jack@suse.cz> Cc: Michal Hocko <mhocko@suse.com> Cc: Kirill Shutemov <kirill@shutemov.name> Cc: Hugh Dickins <hughd@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
