commit 5d69703263d588dbb03f4e57091afd8942d96e6d upstream.
This patch fixes a regression that was introduced by
commit 0a5f38467765ee15478db90d81e40c269c8dda20
davinci_emac: Add Carrier Link OK check in Davinci RX Handler
Said commit adds a check whether the carrier link is ok. If the link is
not ok, the skb is freed and no new dma descriptor added to the rx dma
channel. This causes trouble during initialization when the carrier
status has not yet been updated. If a lot of packets are received while
netif_carrier_ok returns false, all dma descriptors are freed and the
rx dma transfer is stopped.
The bug occurs when the board is connected to a network with lots of
traffic and the ifconfig down/up is done, e.g., when reconfiguring
the interface with DHCP.
The bug can be reproduced by flood pinging the davinci board while doing
ifconfig eth0 down
ifconfig eth0 up
on the board.
After that, the rx path stops working and the overrun value reported
by ifconfig is counting up.
This patch reverts commit 0a5f38467765ee15478db90d81e40c269c8dda20
and instead issues warnings only if cpdma_chan_submit returns -ENOMEM.

commit ba9adbe67e288823ac1deb7f11576ab5653f833e upstream.
Set the RX FIFO flush watermark lower.
According to Federico and JMicron's reply,
setting it to 16QW would be stable on most platforms.
Otherwise, user might experience packet drop issue.

commit 2504a6423b9ab4c36df78227055995644de19edb upstream.
Rate control algorithms are supposed to stop processing when they
encounter a rate with the index -1. Checking for rate->count not being
zero is not enough.
Allowing a rate with negative index leads to memory corruption in
ath_debug_stat_rc().
One consequence of the bug is discussed at

[ Upstream commit 3013dc0cceb9baaf25d5624034eeaa259bf99004 ]
Jean Delvare reported bonding on top of 3c59x adapters was not detecting
network cable removal fast enough.
3c59x indeed uses a 60 seconds timer to check link status if carrier is
on, and 5 seconds if carrier is off.
This patch reduces timer period to 5 seconds if device is a bonding
slave.

Gergely Kalman reported crashes in check_peer_redir().
It appears commit f39925dbde778 (ipv4: Cache learned redirect
information in inetpeer.) added a race, leading to possible NULL ptr
dereference.
Since we can now change dst neighbour, we should make sure a reader can
safely use a neighbour.
Add RCU protection to dst neighbour, and make sure check_peer_redir()
can be called safely by different cpus in parallel.
As neighbours are already freed after one RCU grace period, this patch
should not add typical RCU penalty (cache cold effects)
Many thanks to Gergely for providing a pretty report pointing to the
bug.

[ Upstream commit b924551bed09f61b64f21bffe241afc5526b091a ]
bond_alb_init_slave() is called from bond_enslave() and sets the slave's MAC
address. This is done differently for TLB and ALB modes.
bond->alb_info.rlb_enabled is used to discriminate between the two modes but
this flag may be uninitialized if the slave is being enslaved prior to calling
bond_open() -> bond_alb_initialize() on the master.
It turns out all the callers of alb_set_slave_mac_addr() pass
bond->alb_info.rlb_enabled as the hw parameter.
This patch cleans up the unnecessary parameter of alb_set_slave_mac_addr() and
makes the function decide based on the bonding mode instead, which fixes the
above problem.

commit dfd00c4c8f3dfa1fd7cec45f83d98b2a49743dcd upstream.
Same devices can generate interrupt without properly setting bit in
INT_SOURCE_CSR register (spurious interrupt), what will cause IRQ line
will be disabled by interrupts controller driver.
We discovered that clearing INT_MASK_CSR stops such behaviour. We
previously first read that register, and then clear all know interrupt
sources bits and do not touch reserved bits. After this patch, we write
to all register content (I believe writing to reserved bits on that
register will not cause any problems, I tested that on my rt2800pci
device).
This fix very bad performance problem, practically making device
unusable (since worked without interrupts), reported in:
https://bugzilla.redhat.com/show_bug.cgi?id=658451
We previously tried to workaround that issue in commit
4ba7d9997869d25bd223dea7536fc1ce9fab3b3b "rt2800pci: handle spurious
interrupts", but it was reverted in commit
82e5fc2a34fa9ffea38f00c4066b7e600a0ca5e6
as thing, that will prevent to detect real spurious interrupts.

commit f7d9821a6a9c83450ac35e76d3709e32fd38b76f upstream.
If slave device already has a receive handler registered, then the
error unwind of bonding device enslave function is broken.
The following will leave a pointer to freed memory in the slave
device list, causing a later kernel panic.
# modprobe dummy
# ip li add dummy0-1 link dummy0 type macvlan
# modprobe bonding
# echo +dummy0 >/sys/class/net/bond0/bonding/slaves
The fix is to detach the slave (which removes it from the list)
in the unwind path.

commit 6c15d74defd38e7e7f8805392578b7a1d508097e upstream.
At this point if skb->len happens to be 2, the subsequant skb_pull(skb, 4)
call won't work and the skb->len won't be decreased and won't ever reach 0,
resulting in an infinite loop.
With an ASIX 88772 under heavy load, without this patch, rx_fixup() reaches
an infinite loop in less than a minute. With this patch applied,
no infinite loop even after hours of heavy load.

commit 2d1618170eb493d18f66f2ac03775409a6fb97c6 upstream.
priv->work must not be synced while priv->mutex is locked, because
the mutex is taken in the work handler.
Move cancel_work_sync down to after the device shutdown code.
This is safe, because the work handler checks fw_state and bails out
early in case of a race.

commit ed66ba472a742cd8df37d7072804b2111cdb1014 upstream.
The generic powersaving code that determines after reception of a frame
whether the device should go back to sleep or whether is could stay
awake was calling rt2x00lib_config directly from RX tasklet context.
On a number of the devices this call can actually sleep, due to having
to confirm that the sleeping commands have been executed successfully.
Fix this by moving the call to rt2x00lib_config to a workqueue call.
This fixes bug https://bugzilla.redhat.com/show_bug.cgi?id=731672

Upstream commit effd4d9aece9184f526e6556786a94d335e38b71.
Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.
This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.
Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.
This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD'
I have seen in P2P testing, but it is likely
that there are other errors caused by this.

[ Upstream commit d0e5d83284dac15c015bb48115b6780f5a6413cd ]
If a VM is saved and restored (or migrated) the netback driver will no
longer process any Tx packets from the frontend. xenvif_up() does not
schedule the processing of any pending Tx requests from the front end
because the carrier is off. Without this initial kick the frontend
just adds Tx requests to the ring without raising an event (until the
ring is full).
This was caused by 47103041e91794acdbc6165da0ae288d844c820b (net:
xen-netback: convert to hw_features) which reordered the calls to
xenvif_up() and netif_carrier_on() in xenvif_connect().

[ Upstream commit 4d97480b1806e883eb1c7889d4e7a87e936e06d9 ]
The bond->recv_probe is called in bond_handle_frame() when
a packet is received, but bond_close() sets it to NULL. So,
a panic occurs when both functions work in parallel.
Why this happen:
After null pointer check of bond->recv_probe, an sk_buff is
duplicated and bond->recv_probe is called in bond_handle_frame.
So, a panic occurs when bond_close() is called between the
check and call of bond->recv_probe.
Patch:
This patch uses a local function pointer of bond->recv_probe
in bond_handle_frame(). So, it can avoid the null pointer
dereference.

commit 6cd9d21a0c1e2648c07c32c66bb25795ad3208aa upstream.
We were using incorrect max and min dwell times during forced passive
scans because we were still using the active scan states to scan
(passively) the channels that were not marked as passive.
Instead of doing passive scans in active states, we now skip active
states and scan for all channels in passive states.
