[ Upstream commit 8678fd31f2d3eb14f2b8b39c9bc266f16fa24b22 ]
When receiving a beacon or probe response, we should update the
boottime_ns field which is the timestamp the frame was received at.
(cf mac80211.h)
This fixes a scanning issue with Android since it relies on this
timestamp to determine when the AP has been seen for the last time
(via the nl80211 BSS_LAST_SEEN_BOOTTIME parameter).

[ Upstream commit 0be883a0d795d9146f5325de582584147dd0dcdc ]
The check for count appears to be incorrect since a non-zero count
check occurs a couple of statements earlier. Currently the check is
always false and the dev->port->irq != PARPORT_IRQ_NONE part of the
check is never tested and the if statement is dead-code. Fix this
by removing the check on count.
Note that this code is pre-git history, so I can't find a sha for
it.

[ Upstream commit 9c1587d99f9305aa4f10b47fcf1981012aa5381f ]
The set/clear of the otg control values is done writing to
two different 16bit registers, however we setup the regmap
width for isp1760/61 to 32bit value bits.
So, just access the clear register address (0x376)as the high
part of the otg control register set (0x374), and write the
values in one go to make sure they get clear/set.

[ Upstream commit a76b57311b1a247e31b055872d021c38707dc3a8 ]
When P2P roc is removed, the IWL_MVM_STATUS_NEED_FLUSH_P2P bit is set
to indicate to iwl_mvm_roc_done_wk() that the removed roc is a P2P
one, so it will flush the broadcast station and not the aux station.
However, since setting this bit and scheduling the worker is done
in roc ended flow as well as in case the roc is removed, there is
a race where the worker has already started running (but did not
test this bit yet) and then it is scheduled again. In this case,
the first run of the worker will clear this bit, and thus the second
run will find it already cleared and will try to flush and remove
the aux station by mistake.
Fix it by scheduling the worker only if this bit is not yet set. In
case this bit is already set, the worker is either running or
scheduled, so there is no need to re-schedule it.

[ Upstream commit c6ce1c74ef2923b8ffd85f7f8b486f804f343b39 ]
When TVQM is enabled (iwl_mvm_has_new_tx_api() is true), then
queue numbers are just sequentially assigned 0, 1, 2, ...
Prior to TVQM, in DQA, there were some statically allocated
queue numbers:
* IWL_MVM_DQA_AUX_QUEUE == 1,
* both IWL_MVM_DQA_INJECT_MONITOR_QUEUE and
IWL_MVM_DQA_P2P_DEVICE_QUEUE == 2, and
* IWL_MVM_DQA_AP_PROBE_RESP_QUEUE == 9.
Now, these values are assigned to the members mvm->aux_queue,
mvm->snif_queue, mvm->probe_queue and mvm->p2p_dev_queue by
default. Normally, this doesn't really matter, and if TVQM is
in fact available we override them to the real values after
allocating a queue for use there.
However, this allocation doesn't always happen. For example,
for mvm->p2p_dev_queue (== 2) it only happens when the P2P
Device interface is started, if any. If it's not started, the
value in mvm->p2p_dev_queue remains 2. This wouldn't really
matter all that much if it weren't for iwl_mvm_is_static_queue()
which checks a queue number against one of those four static
numbers.
Now, if no P2P Device or monitor interface is added then queue
2 may be dynamically allocated, yet alias mvm->p2p_dev_queue or
mvm->snif_queue, and thus iwl_mvm_is_static_queue() erroneously
returns true for it. If it then gets full, all interface queues
are stopped, instead of just backpressuring against the one TXQ
that's really the only affected one.
This clearly can lead to issues, as everything is stopped even
if just a single TXQ filled its corresponding HW queue, if it
happens to have an appropriate number (2 or 9, AUX is always
reassigned.) Due to a mac80211 bug, this also led to a situation
in which the queues remained stopped across a deauthentication
and then attempts to connect to a new AP started failing, but
that's fixed separately.
Fix all of this by simply initializing the queue numbers to
the invalid value until they're used, if TVQM is enabled, and
also setting them back to that value when the queues are later
freed again.

When switching op-modes, or more generally when reconfiguring,
we might switch the RB size. In _iwl_pcie_rx_init() we have a
comment saying we must free all RBs since we might switch the

NFS implements blocking locks by blocking inside its lock method. In
the reexport case, this blocks the nfs server thread, which could lead
to deadlocks since an nfs server thread might be required to unlock the
conflicting lock. It also causes a crash, since the nfs server thread
assumes it can free the lock when its lm_notify lock callback is called.
Ideal would be to make the nfs lock method return without blocking in
this case, but for now it works just not to attempt blocking locks. The
difference is just that the original client will have to poll (as it
does in the v4.0 case) instead of getting a callback when the lock's
available.

On systems with multiple SH per SE compute_static_thread_mgmt_se#
is split into independent masks, one for each SH, in the upper and

alternate SHs, then finally to higher CU id. This ensures that
the maximum number of SPIs are engaged as early as possible while
balancing CU assignment to each SH.
v2: Use max SH/SE rather than max SH in cu_per_sh.
v3: Fix comment blocks, ensure se_mask is initially zero filled,
and correctly assign se.sh.cu positions to unset bits in cu_mask.

[ Upstream commit 0c75fc7193387776c10f7c7b440d93496e3d5e21 ]
When more than one FE is connected to a BE, e.g. in a mixing use case,
the BE can be triggered multiple times when the FE are opened/started
concurrently. This race condition is problematic in the case of
SoundWire BE dailinks, and this is not desirable in a general
case. The code carefully checks when the BE can be stopped or
hw_free'ed, but the trigger code does not use any mutual exclusion.
Fix by using the same spinlock already used to check FE states, and
set the state before the trigger. In case of errors, the initial
state will be restored.
This patch does not change how the triggers are handled, it only makes
sure the states are handled in critical sections.

[ Upstream commit b8731209958a1dffccc2888121f4c0280c990550 ]
xhci-mtk depends on xhci's internal virt_dev when it retrieves its
internal data from usb_host_endpoint both in add_endpoint and
drop_endpoint callbacks. But when setup packet was retired by
transaction errors in xhci_setup_device() path, a virt_dev for the slot
is newly created with real_port 0. This leads to xhci-mtks's NULL pointer
dereference from drop_endpoint callback as xhci-mtk assumes that virt_dev's
real_port is always started from one. The similar problems were addressed
by [1] but that can't cover the failure cases from setup_device.
This patch drops the usages of xhci's virt_dev in xhci-mtk's drop_endpoint
callback by adopting rhashtable for searching mtk's schedule entity
from a given usb_host_endpoint pointer instead of searching a linked list.
So mtk's drop_endpoint callback doesn't have to rely on virt_dev at all.

vhci_hcd accepts port resets only when the device doesn't have
port address assigned to it. When reset happens device is in
assigned/used state and vhci_hcd rejects it leaving the port in
a stuck state.
This problem was found when a blue-tooth or xbox wireless dongle
was passed through using usbip.
A few drivers reset the port during probe including mt76 driver
specific to this bug report. Fix the problem with a change to
honor reset requests when device is in used state (VDEV_ST_USED).

In vhci_device_unlink_cleanup(), the URBs for unsent unlink requests are
not given back. This sometimes causes usb_kill_urb to wait indefinitely
for that urb to be given back. syzbot has reported a hung task issue [1]

[ Upstream commit 2847c46c61486fd8bca9136a6e27177212e78c69 ]
This reverts commit 5d5323a6f3625f101dbfa94ba3ef7706cce38760.
That commit effectively disabled Intel host initiated U1/U2 lpm for devices
with periodic endpoints.
Before that commit we disabled host initiated U1/U2 lpm if the exit latency
was larger than any periodic endpoint service interval, this is according
to xhci spec xhci 1.1 specification section 4.23.5.2
After that commit we incorrectly checked that service interval was smaller
than U1/U2 inactivity timeout. This is not relevant, and can't happen for
Intel hosts as previously set U1/U2 timeout = 105% * service interval.
Patch claimed it solved cases where devices can't be enumerated because of
bandwidth issues. This might be true but it's a side effect of accidentally
turning off lpm.
exit latency calculations have been revised since then

[ Upstream commit c0e9422c4e6ca9abd4bd6e1598400c7231eb600b ]
Currently, most pktgen samples print the execution result when the
program is terminated normally. However, sample03 doesn't work
appropriately.
This is results of samples:
# DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 1
Running... ctrl^C to stop
Device: eth0@0
Result: OK: 19(c5+d13) usec, 1 (60byte,0frags)
51762pps 24Mb/sec (24845760bps) errors: 0
# DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample03_burst_single_flow.sh -n 1
Running... ctrl^C to stop
The reason why it doesn't print the execution result when the program is
terminated usually is that sample03 doesn't call the function which
prints the result, unlike other samples.
So, this commit solves this issue by calling the function before
termination. Also, this commit changes control_c function to
print_result to maintain consistency with other samples.

[ Upstream commit e72a55f2e5ddcfb3dce0701caf925ce435b87682 ]
When a read/write command is sent via ioctl to the kernel,
and the command fails, the actual error response of the emmc
is not sent to the user.
IOCTL read/write tests are carried out using commands
17 (Single BLock Read), 24 (Single Block Write),
18 (Multi Block Read), 25 (Multi Block Write)
The tests are carried out on a 64Gb emmc device. All of these
tests try to access an "out of range" sector address (0x09B2FFFF).
It is seen that without the patch the response received by the user
is not OUT_OF_RANGE error (R1 response 31st bit is not set) as per
JEDEC specification. After applying the patch proper response is seen.
This is because the function returns without copying the response to
the user in case of failure. This patch fixes the issue.
Hence, this memcpy is required whether we get an error response or not.
Therefor it is moved up from the current position up to immediately
after we have called mmc_wait_for_req().
The test code and the output of only the CMD17 is included in the
commit to limit the message length.
CMD17 (Test Code Snippet):
==========================
printf("Forming CMD%d\n", opt_idx);
/* single block read */
cmd.blksz = 512;
cmd.blocks = 1;
cmd.write_flag = 0;
cmd.opcode = 17;
//cmd.arg = atoi(argv[3]);
cmd.arg = 0x09B2FFFF;
/* Expecting response R1B */
cmd.flags = MMC_RSP_SPI_R1 | MMC_RSP_R1 | MMC_CMD_ADTC;
memset(data, 0, sizeof(__u8) * 512);
mmc_ioc_cmd_set_data(cmd, data);
printf("Sending CMD%d: ARG[0x%08x]\n", opt_idx, cmd.arg);
if(ioctl(fd, MMC_IOC_CMD, &cmd))
perror("Error");
printf("\nResponse: %08x\n", cmd.response[0]);

[ Upstream commit 3ac5e45291f3f0d699a721357380d4593bc2dcb3 ]
For unexplained reasons, the prescaler register for this device needs to
be cleared (set to 1) while performing a data read or else the command
will hang. This does not appear to affect the real clock rate sent out
on the bus, so I assume it's purely to work around a hardware bug.
During normal operation, the prescaler is already set to 1, so nothing
needs to be done. However, in "initial mode" (which is used for sub-MHz
clock speeds, like the core sets while enumerating cards), it's set to
128 and so we need to reset it during data reads. We currently fail to
do this for long reads.
This has no functional affect on the driver's operation currently
written, as the MMC core always sets a clock above 1MHz before
attempting any long reads. However, the core could conceivably set any
clock speed at any time and the driver should still work, so I think
this fix is worthwhile.
I personally encountered this issue while performing data recovery on an
external chip. My connections had poor signal integrity, so I modified
the core code to reduce the clock speed. Without this change, I saw the
card enumerate but was unable to actually read any data.
Writes don't seem to work in the situation described above even with
this change (and even if the workaround is extended to encompass data
write commands). I was not able to find a way to get them working.

[ Upstream commit cceaa89f02f15f232391ae4be214137b0a0285c0 ]
When using the NO_HOLES feature and expanding the size of an inode, we
update the inode's last_trans, last_sub_trans and last_log_commit fields
at maybe_insert_hole() so that a fsync does know that the inode needs to
be logged (by making sure that btrfs_inode_in_log() returns false). This
happens for expanding truncate operations, buffered writes, direct IO
writes and when cloning extents to an offset greater than the inode's
i_size.
However the way we do it is racy, because in between setting the inode's
last_sub_trans and last_log_commit fields, the log transaction ID that was
assigned to last_sub_trans might be committed before we read the root's
last_log_commit and assign that value to last_log_commit. If that happens
it would make a future call to btrfs_inode_in_log() return true. This is
a race that should be extremely unlikely to be hit in practice, and it is
the same that was described by commit bc0939fcfab0d7 ("btrfs: fix race
between marking inode needs to be logged and log syncing").
The fix would simply be to set last_log_commit to the value we assigned
to last_sub_trans minus 1, like it was done in that commit. However
updating these two fields plus the last_trans field is pointless here
because all the callers of btrfs_cont_expand() (which is the only
caller of maybe_insert_hole()) always call btrfs_set_inode_last_trans()
or btrfs_update_inode() after calling btrfs_cont_expand(). Calling either
btrfs_set_inode_last_trans() or btrfs_update_inode() guarantees that the
next fsync will log the inode, as it makes btrfs_inode_in_log() return
false.
So just remove the code that explicitly sets the inode's last_trans,
last_sub_trans and last_log_commit fields.

As far as I can tell, this is a bug with the m68kmmu architecture, not
with my driver:
The CONFIG_ISA_DMA_API option is provided for coldfire, which implements it,
but dragonball also sets the option as a side-effect, without actually
implementing
the interfaces. The patch below should fix it.
