2017-12-11usb: dwc3: of-simple: set dev_pm_opsMasahiro Yamada1-0/+1
dwc3_of_simple_dev_pm_ops has never been used since the initial support by commit 16adc674d0d6 ("usb: dwc3: add generic OF glue layer"). I guess it just missed to set .pm struct member. Signed-off-by: Masahiro Yamada <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>
2017-12-11usb: dwc3: of-simple: fix missing clk_disable_unprepareAndreas Platschek1-1/+3
If of_clk_get() fails, the clean-up of already initialized clocks should be the same as when clk_prepare_enable() fails. Thus a clk_disable_unprepare() for each clock should be called before the clk_put(). Found by Linux Driver Verification project (linuxtesting.org).

2017-12-11ovl: don't follow redirects if redirect_dir=offMiklos Szeredi5-17/+113
Overlayfs is following redirects even when redirects are disabled. If this is unintentional (probably the majority of cases) then this can be a problem. E.g. upper layer comes from untrusted USB drive, and attacker crafts a redirect to enable read access to otherwise unreadable directories. If "redirect_dir=off", then turn off following as well as creation of redirects. If "redirect_dir=follow", then turn on following, but turn off creation of redirects (which is what "redirect_dir=off" does now). This is a backward incompatible change, so make it dependent on a config option. Reported-by: David Howells <[email protected]> Signed-off-by: Miklos Szeredi <[email protected]>

Due to overlap between commit 1281103770e9 ("mac80211: Simplify locking in ieee80211_sta_tear_down_BA_sessions()") and the way that Luca modified commit 72e2c3438ba3 ("mac80211: tear down RX aggregations first") when sending it upstream from Intel's internal tree, we get the following warning: WARNING: CPU: 0 PID: 5472 at net/mac80211/agg-tx.c:315 ___ieee80211_stop_tx_ba_session+0x158/0x1f0 since there's no appropriate locking around the call to ___ieee80211_stop_tx_ba_session; Sara's original just had a call to the locked __ieee80211_stop_tx_ba_session (one less underscore) but it looks like Luca modified both of the calls when fixing it up for upstream, leading to the problem at hand.

2017-12-10ext4: add missing error check in __ext4_new_inode()Theodore Ts'o1-0/+2
It's possible for ext4_get_acl() to return an ERR_PTR. So we need to add a check for this case in __ext4_new_inode(). Otherwise on an error we can end up oops the kernel. This was getting triggered by xfstests generic/388, which is a test which exercises the shutdown code path. Signed-off-by: Theodore Ts'o <[email protected]> Cc: [email protected]

2017-12-11dmaengine: dmatest: move callback wait queue to thread contextAdam Wallis1-24/+31
Commit adfa543e7314 ("dmatest: don't use set_freezable_with_signal()") introduced a bug (that is in fact documented by the patch commit text) that leaves behind a dangling pointer. Since the done_wait structure is allocated on the stack, future invocations to the DMATEST can produce undesirable results (e.g., corrupted spinlocks). Commit a9df21e34b42 ("dmaengine: dmatest: warn user when dma test times out") attempted to WARN the user that the stack was likely corrupted but did not fix the actual issue. This patch fixes the issue by pushing the wait queue and callback structs into the the thread structure. If a failure occurs due to time, dmaengine_terminate_all will force the callback to safely call wake_up_all() without possibility of using a freed pointer.

2017-12-08xfs: make iomap_begin functions trim iomaps consistentlyDarrick J. Wong1-1/+1
Historically, the XFS iomap_begin function only returned mappings for exactly the range queried, i.e. it doesn't do XFS_BMAPI_ENTIRE lookups. The current vfs iomap consumers are only set up to deal with trimmed mappings. xfs_xattr_iomap_begin does BMAPI_ENTIRE lookups, which is inconsistent with the current iomap usage. Remove the flag so that both iomap_begin functions behave the same way. FWIW this also fixes a behavioral regression in xattr FIEMAP that was introduced in 4.8 wherein attr fork extents are no longer trimmed like they used to be. Signed-off-by: Darrick J.

2017-12-08xfs: remove "no-allocation" reservations for file creationsChristoph Hellwig6-51/+14
If we create a new file we will need an inode, and usually some metadata in the parent direction. Aiming for everything to go well despite the lack of a reservation leads to dirty transactions cancelled under a heavy create/delete load. This patch removes those nospace transactions, which will lead to slightly earlier ENOSPC on some workloads, but instead prevent file system shutdowns due to cancelling dirty transactions for others. A customer could observe assertations failures and shutdowns due to cancelation of dirty transactions during heavy NFS workloads as shown below: 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728125] XFS: Assertion failed: error != -ENOSPC, file: fs/xfs/xfs_inode.c, line: 1262 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728222] Call Trace: 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728246] [<ffffffff81795daf>] dump_stack+0x63/0x81 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728262] [<ffffffff810a1a5a>] warn_slowpath_common+0x8a/0xc0 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728264] [<ffffffff810a1b8a>] warn_slowpath_null+0x1a/0x20 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728285] [<ffffffffa01bf403>] asswarn+0x33/0x40 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728308] [<ffffffffa01bb07e>] xfs_create+0x7be/0x7d0 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728329] [<ffffffffa01b6ffb>] xfs_generic_create+0x1fb/0x2e0 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728348] [<ffffffffa01b7114>] xfs_vn_mknod+0x14/0x20 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728366] [<ffffffffa01b7153>] xfs_vn_create+0x13/0x20 [xfs] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728380] [<ffffffff81231de5>] vfs_create+0xd5/0x140 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728390] [<ffffffffa045ddb9>] do_nfsd_create+0x499/0x610 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728396] [<ffffffffa0465fa5>] nfsd3_proc_create+0x135/0x210 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728401] [<ffffffffa04561e3>] nfsd_dispatch+0xc3/0x210 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728416] [<ffffffffa03bfa43>] svc_process_common+0x453/0x6f0 [sunrpc] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728423] [<ffffffffa03bfdf3>] svc_process+0x113/0x1f0 [sunrpc] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728427] [<ffffffffa0455bcf>] nfsd+0x10f/0x180 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728432] [<ffffffffa0455ac0>] ? nfsd_destroy+0x80/0x80 [nfsd] 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728438] [<ffffffff810c0d58>] kthread+0xd8/0xf0 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728441] [<ffffffff810c0c80>] ? kthread_create_on_node+0x1b0/0x1b0 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728451] [<ffffffff8179d962>] ret_from_fork+0x42/0x70 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728453] [<ffffffff810c0c80>] ? kthread_create_on_node+0x1b0/0x1b0 2017-05-30 21:17:06 kernel: WARNING: [ 2670.728454] ---[ end trace f9822c842fec81d4 ]--- 2017-05-30 21:17:06 kernel: ALERT: [ 2670.728477] XFS (sdb): Internal error xfs_trans_cancel at line 983 of file fs/xfs/xfs_trans.c.

2017-12-08tcp: evaluate packet losses upon RTT changeYuchung Cheng1-11/+8
RACK skips an ACK unless it advances the most recently delivered TX timestamp (rack.mstamp). Since RACK also uses the most recent RTT to decide if a packet is lost, RACK should still run the loss detection whenever the most recent RTT changes. For example, an ACK that does not advance the timestamp but triggers the cwnd undo due to reordering, would then use the most recent (higher) RTT measurement to detect further losses.

2017-12-08tcp: correctly test congestion state in RACKYuchung Cheng1-1/+2
RACK does not test the loss recovery state correctly to compute the reordering window. It assumes if lost_out is zero then TCP is not in loss recovery. But it can be zero during recovery before calling tcp_rack_detect_loss(): when an ACK acknowledges all packets marked lost before receiving this ACK, but has not yet to discover new ones by tcp_rack_detect_loss(). The fix is to simply test the congestion state directly.

2017-12-08tcp_bbr: reset full pipe detection on loss recovery undoNeal Cardwell1-0/+4
Fix BBR so that upon notification of a loss recovery undo BBR resets the full pipe detection (STARTUP exit) state machine. Under high reordering, reordering events can be interpreted as loss. If the reordering and spurious loss estimates are high enough, this could previously cause BBR to spuriously estimate that the pipe is full. Since spurious loss recovery means that our overall sending will have slowed down spuriously, this commit gives a flow more time to probe robustly for bandwidth and decide the pipe is really full.
