2022-01-30Revert "fs/9p: search open fids first"Dominique Martinet
This reverts commit 478ba09edc1f2f2ee27180a06150cb2d1a686f9c. That commit was meant as a fix for setattrs with by fd (e.g. ftruncate) to use an open fid instead of the first fid it found on lookup. The proper fix for that is to use the fid associated with the open file struct, available in iattr->ia_file for such operations, and was actually done just before in 66246641609b ("9p: retrieve fid from file when file instance exist.") As such, this commit is no longer required. Furthermore, changing lookup to return open fids first had unwanted side effects, as it turns out the protocol forbids the use of open fids for further walks (e.g. clone_fid) and we broke mounts for some servers enforcing this rule. Note this only reverts to the old working behaviour, but it's still possible for lookup to return open fids if dentry->d_fsdata is not set, so more work is needed to make sure we respect this rule in the future, for example by adding a flag to the lookup functions to only match certain fid open modes depending on caller requirements.

commit 6f1b228529ae introduces a regression which can deadlock as follows: Task1: Task2: jbd2_journal_commit_transaction ocfs2_test_bg_bit_allocatable spin_lock(&jh->b_state_lock) jbd_lock_bh_journal_head __jbd2_journal_remove_checkpoint spin_lock(&jh->b_state_lock) jbd2_journal_put_journal_head jbd_lock_bh_journal_head Task1 and Task2 lock bh->b_state and jh->b_state_lock in different order, which finally result in a deadlock. So use jbd2_journal_[grab|put]_journal_head instead in ocfs2_test_bg_bit_allocatable() to fix it.

2022-01-30kasan: test: fix compatibility with FORTIFY_SOURCEMarco Elver
With CONFIG_FORTIFY_SOURCE enabled, string functions will also perform dynamic checks using __builtin_object_size(ptr), which when failed will panic the kernel. Because the KASAN test deliberately performs out-of-bounds operations, the kernel panics with FORTIFY_SOURCE, for example: | kernel BUG at lib/string_helpers.c:910! | invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI | CPU: 1 PID: 137 Comm: kunit_try_catch Tainted: G B 5.16.0-rc3+ #3 | Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 | RIP: 0010:fortify_panic+0x19/0x1b | ... | Call Trace: | kmalloc_oob_in_memset.cold+0x16/0x16 | ... Fix it by also hiding `ptr` from the optimizer, which will ensure that __builtin_object_size() does not return a valid size, preventing fortified string functions from panicking.

2022-01-30memory-failure: fetch compound_head after pgmap_pfn_valid()Joao Martins
memory_failure_dev_pagemap() at the moment assumes base pages (e.g. dax_lock_page()). For devmap with compound pages fetch the compound_head in case a tail page memory failure is being handled. Currently this is a nop, but in the advent of compound pages in dev_pagemap it allows memory_failure_dev_pagemap() to keep working. Without this fix memory-failure handling (i.e. MCEs on pmem) with device-dax configured namespaces will regress (and crash).

2022-01-29cifs: unlock chan_lock before calling cifs_put_tcp_sessionShyam Prasad N
While removing an smb session, we need to free up the tcp session for each channel for that session. We were doing this with chan_lock held. This results in a cyclic dependency with cifs_tcp_ses_lock. For now, unlock the chan_lock temporarily before calling cifs_put_tcp_session. This should not cause any problem for now, since we do not remove channels anywhere else. And this code segment will not be called by two threads. When we do implement the code for removing channels, we will need to execute proper ref counting here.

Record the start_time for a bio but defer the starting block core's IO accounting until after IO is submitted using bio_start_io_acct_time().
