The JDI WUXGA LVDS panel works in LDB split mode.

commit d55966c4279bfc6a0cf0b32bf13f5df228a1eeb6 upstream.
There was some logic added a while ago to clear out f_bavail in statfs()
if we did not have enough free metadata space to satisfy our global
reserve. This was incorrect at the time, however didn't really pose a
problem for normal file systems because we would often allocate chunks
if we got this low on free metadata space, and thus wouldn't really hit
this case unless we were actually full.
Fast forward to today and now we are much better about not allocating
metadata chunks all of the time. Couple this with d792b0f197 ("btrfs:
always reserve our entire size for the global reserve") which now means
we'll easily have a larger global reserve than our free space, we are
now more likely to trip over this while still having plenty of space.
Fix this by skipping this logic if the global rsv's space_info is not
full. space_info->full is 0 unless we've attempted to allocate a chunk
for that space_info and that has failed. If this happens then the space
for the global reserve is definitely sacred and we need to report
b_avail == 0, but before then we can just use our calculated b_avail.

The driver for Cisco Aironet 4500 and 4800 series cards (airo.c),
implements AIROOLDIOCTL/SIOCDEVPRIVATE in airo_ioctl().
The ioctl handler copies an aironet_ioctl struct from userspace, which
includes a command. Some of the commands are handled in readrids(),
where the user controlled command is converted into a driver-internal
value called "ridcode".
There are two command values, AIROGWEPKTMP and AIROGWEPKNV, which
correspond to ridcode values of RID_WEP_TEMP and RID_WEP_PERM
respectively. These commands both have checks that the user has
CAP_NET_ADMIN, with the comment that "Only super-user can read WEP
keys", otherwise they return -EPERM.
However there is another command value, AIRORRID, that lets the user
specify the ridcode value directly, with no other checks. This means
the user can bypass the CAP_NET_ADMIN check on AIROGWEPKTMP and
AIROGWEPKNV.
Fix it by moving the CAP_NET_ADMIN check out of the command handling
and instead do it later based on the ridcode. That way regardless of
whether the ridcode is set via AIROGWEPKTMP or AIROGWEPKNV, or passed
in using AIRORID, we always do the CAP_NET_ADMIN check.

The driver for Cisco Aironet 4500 and 4800 series cards (airo.c),
implements AIROOLDIOCTL/SIOCDEVPRIVATE in airo_ioctl().
The ioctl handler copies an aironet_ioctl struct from userspace, which
includes a command and a length. Some of the commands are handled in
readrids(), which kmalloc()'s a buffer of RIDSIZE (2048) bytes.
That buffer is then passed to PC4500_readrid(), which has two cases.
The else case does some setup and then reads up to RIDSIZE bytes from
the hardware into the kmalloc()'ed buffer.
Here len == RIDSIZE, pBuf is the kmalloc()'ed buffer:
// read the rid length field
bap_read(ai, pBuf, 2, BAP1);
// length for remaining part of rid
len = min(len, (int)le16_to_cpu(*(__le16*)pBuf)) - 2;
...
// read remainder of the rid
rc = bap_read(ai, ((__le16*)pBuf)+1, len, BAP1);
PC4500_readrid() then returns to readrids() which does:
len = comp->len;
if (copy_to_user(comp->data, iobuf, min(len, (int)RIDSIZE))) {
Where comp->len is the user controlled length field.
So if the "rid length field" returned by the hardware is < 2048, and
the user requests 2048 bytes in comp->len, we will leak the previous
contents of the kmalloc()'ed buffer to userspace.
Fix it by kzalloc()'ing the buffer.

When a link is going down the driver will be calling fnic_cleanup_io(),
which will traverse all commands and calling 'done' for each found command.
While the traversal is handled under the host_lock, calling 'done' happens
after the host_lock is being dropped.
As fnic_queuecommand_lck() is being called with the host_lock held, it
might well be that it will pick the command being selected for abortion
from the above routine and enqueue it for sending, but then 'done' is being
called on that very command from the above routine.
Which of course confuses the hell out of the scsi midlayer.
So fix this by not queueing commands when fnic_cleanup_io is active.

TKIP replay protection was skipped for the very first frame received
after a new key is configured. While this is potentially needed to avoid
dropping a frame in some cases, this does leave a window for replay
attacks with group-addressed frames at the station side. Any earlier
frame sent by the AP using the same key would be accepted as a valid
frame and the internal RSC would then be updated to the TSC from that
frame. This would allow multiple previously transmitted group-addressed
frames to be replayed until the next valid new group-addressed frame
from the AP is received by the station.
Fix this by limiting the no-replay-protection exception to apply only
for the case where TSC=0, i.e., when this is for the very first frame
protected using the new key, and the local RSC had not been set to a
higher value when configuring the key (which may happen with GTK).

[ Upstream commit 26ec17a1dc5ecdd8d91aba63ead6f8b5ad5dea0d ]
In case a radar event of CAC_FINISHED or RADAR_DETECTED
happens during another phy is during CAC we might need
to cancel that CAC.
If we got a radar in a channel that another phy is now
doing CAC on then the CAC should be canceled there.
If, for example, 2 phys doing CAC on the same channels,
or on comptable channels, once on of them will finish his
CAC the other might need to cancel his CAC, since it is no
longer relevant.
To fix that the commit adds an callback and implement it in
mac80211 to end CAC.
This commit also adds a call to said callback if after a radar
event we see the CAC is no longer relevant

Commit e33e2241e2 ("Revert "cfg80211: Use 5MHz bandwidth by
default when checking usable channels"") fixed a broken
regulatory (leaving channel 12 open for AP where not permitted).
Apply a similar fix to custom regulatory domain processing.

RM500Q is a 5G module from Quectel, supporting both standalone and
non-standalone modes. The normal Quectel quirks apply (DTR and dynamic
interface numbers).

Changing the link mode should also be done for 100BaseFX SGMII modules,
otherwise they just don't work when the default link mode in CTRL_EXT
coming from the EEPROM is SERDES.
Additionally 100Base-LX SGMII SFP modules are also supported now, which
was not the case before.
Tested with an i210 using Flexoptix S.1303.2M.G 100FX and
S.1303.10.G 100LX SGMII SFP modules.

This patch fixes the calculation of queue when we restore flow director
filters after resetting adapter. In ixgbe_fdir_filter_restore(), filter's
vf may be zero which makes the queue outside of the rx_ring array.
The calculation is changed to the same as ixgbe_add_ethtool_fdir_entry().

Currently, though the FDB entry is added to VF, it does not appear in
RAR filters. VF driver only allows to add 10 entries. Attempting to add
another causes an error. This patch removes limitation and allows use of
all free RAR entries for the FDB if needed.

Determined empirically, no documentation is available.
The OLPC XO-1.75 laptop used parent 1, that one being VCTCXO/4 (65MHz), but
thought it's a VCTCXO/2 (130MHz). The mmp2 timer driver, not knowing
what is going on, ended up just dividing the rate as of
commit f36797ee43 ("ARM: mmp/mmp2: dt: enable the clock")'

Any user of wkup_m3_ipc calls wkup_m3_ipc_get to get a handle and this
checks the value of the static variable m3_ipc_state to see if the
wkup_m3 is ready. Currently this is populated during probe before
rproc_boot has been called, meaning there is a window of time that
wkup_m3_ipc_get can return a valid handle but the wkup_m3 itself is not
ready, leading to invalid IPC calls to the wkup_m3 and system
instability.
To avoid this, move the population of the m3_ipc_state variable until
after rproc_boot has succeeded to guarantee a valid and usable handle
is always returned.

Current USB3503 driver ignores GPIO polarity and always operates as if the
GPIO lines were flagged as ACTIVE_HIGH. Fix the polarity for the existing
USB3503 chip applications to match the chip specification and common
convention for naming the pins. The only pin, which has to be ACTIVE_LOW
is the reset pin. The remaining are ACTIVE_HIGH. This change allows later
to fix the USB3503 driver to properly use generic GPIO bindings and read
polarity from DT.
