Pull vfs fixes from Al Viro. - fix io_destroy()/aio_complete() race - the vfs_open() change to get rid of open_check_o_direct() boilerplate was nice, but buggy. Al has a patch avoiding a revert, but that's definitely not a last-day fodder, so for now revert it is... * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: Revert "fs: fold open_check_o_direct into do_dentry_open" fix io_destroy()/aio_complete() race

Al Viro authored
This reverts commit cab64df1. Having vfs_open() in some cases drop the reference to struct file combined with error = vfs_open(path, f, cred); if (error) { put_filp(f); return ERR_PTR(error); } return f; is flat-out wrong. It used to be error = vfs_open(path, f, cred); if (!error) { /* from now on we need fput() to dispose of f */ error = open_check_o_direct(f); if (error) { fput(f); f = ERR_PTR(error); } } else { put_filp(f); f = ERR_PTR(error); } and sure, having that open_check_o_direct() boilerplate gotten rid of is nice, but not that way... Worse, another call chain (via finish_open()) is FUBAR now wrt FILE_OPENED handling - in that case we get error returned, with file already hit by fput() *AND* FILE_OPENED not set. Guess what happens in path_openat(), when it hits if (!(opened & FILE_OPENED)) { BUG_ON(!error); put_filp(file); } The root cause of all that crap is that the callers of do_dentry_open() have no way to tell which way did it fail; while that could be fixed up (by passing something like int *opened to do_dentry_open() and have it marked if we'd called ->open()), it's probably much too late in the cycle to do so right now.

If we end up splitting a bio and the queue goes away between the initial submission and the later split submission, then we can block forever in blk_queue_enter() waiting for the reference to drop to zero. This will never happen, since we already hold a reference. Mark a split bio as already having entered the queue, so we can just use the live non-blocking queue enter variant.

George Boole would have noticed a slight error in 4.16 commit 69d763fc ("mm: pin address_space before dereferencing it while isolating an LRU page"). Fix it, to match both the comment above it, and the original behaviour. Although anonymous pages are not marked PageDirty at first, we have an old habit of calling SetPageDirty when a page is removed from swap cache: so there's a category of ex-swap pages that are easily migratable, but were inadvertently excluded from compaction's async migration in 4.16.

Swapping load on huge=always tmpfs (with khugepaged tuned up to be very eager, but I'm not sure that is relevant) soon hung uninterruptibly, waiting for page lock in shmem_getpage_gfp()'s find_lock_entry(), most often when "cp -a" was trying to write to a smallish file. Debug showed that the page in question was not locked, and page->mapping NULL by now, but page->index consistent with having been in a huge page before. Reproduced in minutes on a 4.15 kernel, even with 4.17's 605ca5ed ("mm/huge_memory.c: reorder operations in __split_huge_page_tail()") added in; but took hours to reproduce on a 4.17 kernel (no idea why). The culprit proved to be the __ClearPageDirty() on tails beyond i_size in __split_huge_page(): the non-atomic __bitoperation may have been safe when 4.8's baa355fd ("thp: file pages support for split_huge_page()") introduced it, but liable to erase PageWaiters after 4.10's 62906027 ("mm: add PageWaiters indicating tasks are waiting for a page bit").

In 64 bit, we have a 4 byte hole between ifindex and netns_dev in the case of struct bpf_map_info but also struct bpf_prog_info. In net-next commit b85fab0e ("bpf: Add gpl_compatible flag to struct bpf_prog_info") added a bitfield into it to expose some flags related to programs. Thus, add an unnamed __u32 bitfield for both so that alignment keeps the same in both 32 and 64 bit cases, and can be naturally extended from there as in b85fab0e.

After commit f6cc9c05, the following conf is broken (note that the default loopback mtu is 65536, ie IP_MAX_MTU + 1): $ ip tunnel add gre1 mode gre local 10.125.0.1 remote 10.125.0.2 dev lo add tunnel "gre0" failed: Invalid argument $ ip l a type dummy $ ip l s dummy1 up $ ip l s dummy1 mtu 65535 $ ip tunnel add gre1 mode gre local 10.125.0.1 remote 10.125.0.2 dev dummy1 add tunnel "gre0" failed: Invalid argument dev_set_mtu() doesn't allow to set a mtu which is too large. First, let's cap the mtu returned by ip_tunnel_bind_dev(). Second, remove the magic value 0xFFF8 and use IP_MAX_MTU instead. 0xFFF8 seems to be there for ages, I don't know why this value was used. With a recent kernel, it's also possible to set a mtu > IP_MAX_MTU: $ ip l s dummy1 mtu 66000 After that patch, it's also possible to bind an ip tunnel on that kind of interface.

Steffen Klassert says: ==================== pull request (net): ipsec 2018-05-31 1) Avoid possible overflow of the offset variable in _decode_session6(), this fixes an infinite lookp there. From Eric Dumazet. 2) We may use an error pointer in the error path of xfrm_bundle_create(). Fix this by returning this pointer directly to the caller. Please pull or let me know if there are problems. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

pblk allocates line bitmaps within the line lock unnecessarily. In order to take pressure out of the fast patch, allocate line bitmaps outside of this lock and refactor accordingly.

Unless we kick the writer directly when setting a new flush point, the user risks having to wait for up to one second (the default timeout for the write thread to be kicked) for the IO to complete.

When switching between different lun configurations, there is no guarantee that all lines that contain closed/open chunks have some valid data to recover. Check that the smeta chunk has been written to instead. Also skip bad lines (that does not have enough good chunks).

In the read path, pblk gets a reference to the incoming bio and puts it after ending the bio. Though this behavior is correct, it is unnecessary since pblk is the one putting the bio, therefore, it cannot disappear underneath it. Removing this reference, allows to clean up rqd->bio and avoids pointer bouncing for the different read paths. Now, the incoming bio always resides in the read context and pblk's internal bios (if any) reside in rqd->bio.

In some cases, users can want set write buffer size manually, e.g. to adjust it to specific workload. This patch provides the possibility to set write buffer size via module parameter feature.
