Konstantin Khlebnikov 23715275e4 netfilter: ip6t_MASQUERADE: add dependency on conntrack module
After commit 4d3a57f23d ("netfilter: conntrack: do not enable connection
tracking unless needed") conntrack is disabled by default unless some
module explicitly declares dependency in particular network namespace.

Michael S. Tsirkin a8ceb5dbfd ptr_ring: add barriers
Users of ptr_ring expect that it's safe to give the
data structure a pointer and have it be available
to consumers, but that actually requires an smb_wmb
or a stronger barrier.

In absence of such barriers and on architectures that reorder writes,
consumer might read an un=initialized value from an skb pointer stored
in the skb array.  This was observed causing crashes.

To fix, add memory barriers.  The barrier we use is a wmb, the
assumption being that producers do not need to read the value so we do
not need to order these reads.

RISC-V: Remove unused CONFIG_HVC_RISCV_SBI code
This is code that probably should never have made it into the kernel in
the first place: it depends on a driver that hadn't been reviewed yet.
During the HVC_SBI_RISCV review process a better way of doing this was
suggested, but that means this code is defunct.  It's compile-time
disabled in 4.15 because the driver isn't in, so I think it's safe to
just remove this for now.

RISC-V: Resurrect smp_mb__after_spinlock()
I removed this last week because of an incorrect comment:
smp_mb__after_spinlock() is actually still used, and is necessary on
RISC-V.  It's been resurrected, with a comment that describes what it
actually does this time.  Thanks to Andrea for finding the bug!

Karol Herbst 6d60ce384d x86/mm/kmmio: Fix mmiotrace for page unaligned addresses
If something calls ioremap() with an address not aligned to PAGE_SIZE, the
returned address might be not aligned as well. This led to a probe
registered on exactly the returned address, but the entire page was armed
for mmiotracing.

On calling iounmap() the address passed to unregister_kmmio_probe() was
PAGE_SIZE aligned by the caller leading to a complete freeze of the
machine.

We should always page align addresses while (un)registerung mappings,
because the mmiotracer works on top of pages, not mappings. We still keep
track of the probes based on their real addresses and lengths though,
because the mmiotrace still needs to know what are mapped memory regions.

Also move the call to mmiotrace_iounmap() prior page aligning the address,
so that all probes are unregistered properly, otherwise the kernel ends up
failing memory allocations randomly after disabling the mmiotracer.

earlyprintk=efi,keep does not work any more with a warning

Boot just hangs because of the earlyprintk within the earlyprintk

This is caused by a new introduced middle state in:

early_ioremap() is fine in both SYSTEM_BOOTING and SYSTEM_SCHEDULING
states, original condition should be updated accordingly.

Rafael J. Wysocki 3487972d7f PM / sleep: Avoid excess pm_runtime_enable() calls in device_resume()
Middle-layer code doing suspend-time optimizations for devices with
the DPM_FLAG_SMART_SUSPEND flag set (currently, the PCI bus type and
the ACPI PM domain) needs to make the core skip ->thaw_early and
->thaw callbacks for those devices in some cases and it sets the
power.direct_complete flag for them for this purpose.

However, it turns out that setting power.direct_complete outside of
the PM core is a bad idea as it triggers an excess invocation of
pm_runtime_enable() in device_resume().

For this reason, provide a helper to clear power.is_late_suspended
and power.is_suspended to be invoked by the middle-layer code in
question instead of setting power.direct_complete and make that code
call the new helper.

Minas Harutyunyan 9273083a15 usb: dwc2: Fix TxFIFOn sizes and total TxFIFO size issues
In host mode reading from DPTXSIZn returning invalid value in
dwc2_check_param_tx_fifo_sizes function.

In total TxFIFO size calculations unnecessarily reducing by ep_info.
hw->total_fifo_size can be fully allocated for FIFO's.

Added num_dev_in_eps member in dwc2_hw_params structure to save number
of IN EPs.

Added g_tx_fifo_size array in dwc2_hw_params structure to store power
on reset values of DPTXSIZn registers in forced device mode.

Updated dwc2_hsotg_tx_fifo_count() function to get TxFIFO count from
num_dev_in_eps.

Updated dwc2_get_dev_hwparams() function to store DPTXFSIZn in
g_tx_fifo_size array.

dwc2_get_host/dev_hwparams() functions call moved after num_dev_in_eps
set from hwcfg4.

Modified dwc2_check_param_tx_fifo_sizes() function to check TxFIFOn
sizes based on g_tx_fifo_size array.

Removed ep_info subtraction during calculation of tx_addr_max in
dwc2_hsotg_tx_fifo_total_depth() function. Also removed
dwc2_hsotg_ep_info_size() function as no more need.

Chengguang Xu e8d4bfe3a7 ovl: Sync upper dirty data when syncing overlayfs
When executing filesystem sync or umount on overlayfs,
dirty data does not get synced as expected on upper filesystem.
This patch fixes sync filesystem method to keep data consistency
for overlayfs.

Miklos Szeredi 438c84c2f0 ovl: don't follow redirects if redirect_dir=off
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.

Johannes Berg 0afe9d4ab9 mac80211: fix locking in ieee80211_sta_tear_down_BA_sessions
Due to overlap between
commit 1281103770 ("mac80211: Simplify locking in ieee80211_sta_tear_down_BA_sessions()")
and the way that Luca modified
commit 72e2c3438b ("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.

Move the locking appropriately to fix this problem.

Theodore Ts'o 996fc4477a ext4: add missing error check in __ext4_new_inode()
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.

Adam Wallis 6f6a23a213 dmaengine: dmatest: move callback wait queue to thread context
Commit adfa543e73 ("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 a9df21e34b ("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.

Darrick J. Wong b7e0b6ff54 xfs: make iomap_begin functions trim iomaps consistently
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.

Christoph Hellwig f59cf5c299 xfs: remove "no-allocation" reservations for file creations
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:
