Firmware expects 'max_ssid_length' field in
'struct mwifiex_ie_types_wildcard_ssid_params' to be '0' for
performing SSID specific scan. Currently driver updates it with
an actual SSID length. Hence UUT is not able to find the AP
configured in hidden SSID mode in scan results and association
fails.

max_ssid_length is filled with '0' to fix the issue.

When HW RF kill switch is set to kill the radio, our NIC issues an
interrupt after we stop the APM module. When we unload the module,
the driver disables and cleans the interrupts before stopping the
APM. So we have a real interrupt (inta not zero) pending.
When this interrupts pops up the tasklet has already been killed
and we crash.

Here is a logical description of the flow:

disable and clean interrupts
synchronize interrupts
kill the tasklet

stop the APM <<== creates an RF kill interrupt

free_irq <<== somehow our ISR is called here and we crash

Here is the panic message:

The AH4/6 ahash input callbacks read out the nexthdr field from the AH

The AH4/6 ahash output callbacks pass nexthdr to xfrm_output_resume
instead of the error code.  This appears to be a copy+paste error from
the input case, where nexthdr is expected.  This causes the driver to
continuously add AH headers to the datagram until either an allocation
fails and the packet is dropped or the ahash driver hits a synchronous
fallback and the resulting monstrosity is transmitted.

Correct this issue by simply passing the error code unadulterated.

When the connection monitor timer fires right before
suspend, the following will happen:
 timer fires -> monitor_work gets queued
 suspend calls ieee80211_sta_quiesce
 ieee80211_sta_quiesce:
  - deletes timer
  - cancels monitor_work synchronously, running it
  [note wrong order of these steps]
 monitor_work runs, re-arming the timer
 later, timer fires while system should be quiesced

This causes a warning:

WARNING: at net/mac80211/util.c:540 ieee80211_can_queue_work+0x35/0x40 [mac80211]()

but is otherwise harmless. I'm not completely sure

Commit 4d9d88d1 by Scott James Remnant <keybuk@google.com> added
the .uevent() callback for the regulatory device used during
the platform device registration. The change was done to account
for queuing up udev change requests through udevadm triggers.
The change also meant that upon regulatory core exit we will now
send a uevent() but the uevent() callback, reg_device_uevent(),
also accessed last_request. Right before commiting device suicide
we free'd last_request but never set it to NULL so
platform_device_unregister() would lead to bogus kernel paging
request. Fix this and also simply supress uevents right before
we commit suicide as they are pointless.

This fix is required for kernels >= v2.6.39

$ git describe --contains 4d9d88d1
v2.6.39-rc1~468^2~25^2^2~21

The impact of not having this present is that a bogus paging
access may occur (only read) upon cfg80211 unload time. You
may also get this BUG complaint below. Although Johannes
could not reproduce the issue this fix is theoretically correct.

When receiving failed PLCP frames is enabled, there
won't be a rate pointer when we add the radiotap
header and thus the kernel will crash. Fix this by
not assuming the rate pointer is always valid. It's
still always valid for frames that have good PLCP
though, and that is checked & enforced.

To prevent the SBus driver for Sun Happy Meal cards from being loaded for
PCI cards utilizing the same chipset, a filter was added to the probe
function in commit 0b492fce.

The filter was implemented by checking the name of the parent node in
the OF tree. This patch extends this filter, so that the driver will
load on SBus systems that are based upon SBI SBus Bridges.

The driver used NET_IP_ALIGN to remove some additional padding inside of
the rx_fixup function. On many architectures NET_IP_ALIGN defaults to 2
which removed the correct amount of bytes.

On MCORE2-machines commit ea812ca1
introduces a change which sets NET_IP_ALIGN to 0 by default. Which
triggered the bug on these machines.

This fix introduces a new RXW_PADDING define and uses this instead of
NET_IP_ALIGN. The name was taken from the original SMSC7500 driver which
is provided by SMSC.

The link down would occur when reseting PHY. And it would take about 2 ~ 5 seconds
from link down to link up. If the delay of pm_schedule_suspend is not long enough,
the device would enter runtime_suspend before link up. After link up, the device
would wake up and reset PHY again. Then, you would find the driver keep in a loop
of runtime_suspend and rumtime_resume.

Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.

Simple way to reproduce the problem in mainline:

    cat >/tmp/a.c <<'EOF'
    #include <unistd.h>
    #include <fcntl.h>
    #include <stdio.h>
    main()
    {
            struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
            if (fcntl(0, F_SETLK, &fl))
                    perror("setlk");
    }
    EOF
    cc /tmp/a.c -o /tmp/test

then on nfs4:

    mount --bind file1 file2
    /tmp/test < file1		# ok
    /tmp/test < file2		# spews "setlk: No locks available"...

What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.

The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks.  I.e.  set LOOKUP_JUMPED...

Commit 32aaeffb (Merge branch

Also check we either have export.h or module.h included
for the files exporting symbols:

Timers set by __set_chan_timer() should use miliseconds instead of
jiffies. Commit 942ecc9c updated
l2cap_set_timer() so it expects timeout to be specified in msecs
instead of jiffies. This makes timeouts unreliable when CONFIG_HZ
is not set to 1000.
