commit 4d907069bc upstream.
The Davicom DM9100 and DM9102 chips are used on the motherboards of
some SPARC systems (supported by the tulip driver) and also in PCI
expansion cards (supported by the dmfe driver). There is no
difference in the PCI device ids for the two different configurations,
so these drivers both claim the device ids. However, it is possible
to distinguish the two configurations by the presence of Open Firmware
properties for them, so we do that.

commit 35bb5cadc8 upstream.
velocity_open() calls velocity_give_many_rx_descs(), which gives RX
descriptors to the NIC, before installing an interrupt handler or
calling velocity_init_registers(). I think this is very unsafe and it
appears to explain the bug report <http://bugs.debian.org/508527>.
On MTU change, velocity_give_many_rx_descs() is again called before
velocity_init_registers(). I'm not sure whether this is unsafe but
it does look wrong.
Therefore, move the calls to velocity_give_many_rx_descs() after
request_irq() and velocity_init_registers().

commit c2572b78aa upstream.
This patch fixes resource reclaim in error path of acm_probe:
1. In the case of "out of memory (read urbs usb_alloc_urb)\n")", there
is no need to call acm_read_buffers_free(acm) here. Fix it by goto
alloc_fail6 instead of alloc_fail7.
2. In the case of "out of memory (write urbs usb_alloc_urb)",
usb_alloc_urb may fail in any iteration of the for loop. Current
implementation does not properly free allocated snd->urb. Fix it by
goto alloc_fail8 instead of alloc_fail7.
3. In the case of device_create_file(&intf->dev,&dev_attr_iCountryCodeRelDate)
fail, acm->country_codes is kfreed. As a result, device_remove_file
for dev_attr_wCountryCodes will not be executed in acm_disconnect.
Fix it by calling device_remove_file for dev_attr_wCountryCodes
before goto skip_countries.

commit 6a1a82df91 upstream.
Call set_mctrl() and clear_mctrl() according to the flow control mode

work when CRTSCTS is not set.
This fixes a regression introduced by 4175f3e31 ("tty_port: If we are
opened non blocking we still need to raise the carrier"). This patch
calls the low-level driver's dtr_rts() function which consequently sets
TIOCM_DTR | TIOCM_RTS. A later call to set_termios() without CRTSCTS in
cflags, however, does not reset these bits, and so data is not actually
sent out on the serial wire.

commit 1038953674 upstream.
Per IEEE 1394 clause 8.4.2.3, a contender for the IRM role shall check
whether the current IRM complies to 1394a-2000 or later. If not force a
compliant node (e.g. itself) to become IRM. This was implemented in the
older ieee1394 driver but not yet in firewire-core.
An older Sony camcorder (Sony DCR-TRV25) which implements 1394-1995 IRM
but neither 1394a-2000 IRM nor BM was now found to cause an
interoperability bug:
- Camcorder becomes root node when plugged in, hence gets IRM role.
- firewire-core successfully contends for BM role, proceeds to perform
gap count optimization and resets the bus.
- Sony camcorder ignores presence of a BM (against the spec, this is
a firmware bug), performs its idea of gap count optimization and
resets the bus.
- Preceding two steps are repeated endlessly, bus never settles,
regular I/O is practically impossible.
http://thread.gmane.org/gmane.linux.kernel.firewire.user/3913
This is an interoperability regression from the old to the new drivers.
Fix it indirectly by adding the 1394a IRM check. The spec suggests
three and a half methods to determine 1394a compliance of a remote IRM;
we choose the method of testing the Config_ROM.Bus_Info.generation
field. This is data that firewire-core should have readily available at
this point, i.e. does not require extra I/O.

commit 566d84d172 upstream.
radeon's have a special ability to passthrough writes in their internal
memory space directly to PCI, this ability means that if some of the internal
surfaces like the depth buffer point at 0x0, any writes to these will
go directly to RAM at 0x0 via PCI busmastering.
Now mesa used to always emit clears after emitting state, since the
radeon mesa driver was refactored a year or more ago, it was found it
could generate a clear request without ever sending any setup state to the
card. So the clear would attempt to clear the depth buffer at 0x0, which
would overwrite main memory at this point. fs corruption ensues.
Also once one app did this correctly, it would never get set back to 0
making this messy to reproduce.
The kernel should block this from happening as mesa runs without privs,
though it does require the user be connected to the current running X session.
This patch implements a check to make sure the depth offset has been set
before a depth clear occurs and if it finds one it prints a warning and
ignores the depth clear request. There is also a mesa fix to avoid sending
the badness going into mesa.
This only affects r100/r200 GPUs in user modesetting mode.

There is a very small race window when writing to a
RAID1 such that if a device is marked faulty at exactly the wrong
time, the write-in-progress will not be sent to the device,
but the bitmap (if present) will be updated to say that
the write was sent.
Then if the device turned out to still be usable as was re-added
to the array, the bitmap-based-resync would skip resyncing that
block, possibly leading to corruption. This would only be a problem
if no further writes were issued to that area of the device (i.e.
that bitmap chunk).

commit 39d3215774 upstream.
I have seen RX stalls on a machine that experienced a suspected
OOM. After the stall, the RX buffer is empty on the guest side
and there are exactly 16 entries available on the host side. As
the number of entries is less than that required by a maximal
skb, the host cannot proceed.
The guest did not have a refill job scheduled.
My diagnosis is that an OOM had occured, with the delayed refill
job scheduled. The job was able to allocate at least one skb, but
not enough to overcome the minimum required by the host to proceed.
As the refill job would only reschedule itself if it failed completely
to allocate any skbs, this would lead to an RX stall.
The following patch removes this stall possibility by always
rescheduling the refill job until the ring is totally refilled.
Testing has shown that the RX stall no longer occurs whereas
previously it would occur within a day.

The SJA1000 command register is concurrently written in the rx-path to free
the receive buffer _and_ in the tx-path to start the transmission.
The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states:
"Between two commands at least one internal clock cycle is needed in
order to proceed. The internal clock is half of the external oscillator
frequency."
On SMP systems the current implementation leads to a write stall in the
tx-path, which can be solved by adding some general locking and some time
to settle the write_reg() operation for the command register.

commit 44ebd037c5 upstream.
The length of the scatter gather list a driver can enqueue is limited by
the bus' sg_tablesize to 62 entries. Each entry will be described by at
least one transfer request block (TRB). If the entry's buffer crosses a
64KB boundary, then that entry will have to be described by two or more
TRBs. So even if the USB device driver respects sg_tablesize, the whole
scatter list may take more than 62 TRBs to describe, and won't fit on
the ring.
Don't assume that an empty ring means there is enough room on the
transfer ring. The old code would unconditionally queue this too-large
transfer, and over write the beginning of the transfer. This would mean
the cycle bit was unchanged in those overwritten transfers, causing the
hardware to think it didn't own the TRBs, and the host would seem to
hang.
Now drivers may see submit_urb() fail with -ENOMEM if the transfers are
too big to fit on the ring.

commit 1624ae1c19 upstream.
When the USB core installs a new interface, it unconditionally clears the
halts on all the endpoints on the new interface. Usually the xHCI host
needs to know when an endpoint is reset, so it can change its internal
endpoint state. In this case, it doesn't care, because the endpoints were
never halted in the first place.
To avoid issuing a redundant Reset Endpoint command, the xHCI driver looks
at xhci_virt_ep->stopped_td to determine if the endpoint was actually
halted. However, the functions that handle the stall never set that
variable to NULL after it dealt with the stall. So if an endpoint stalled
and a Reset Endpoint command completed, and then the class driver tried to
install a new alternate setting, the xHCI driver would access the old
xhci_virt_ep->stopped_td pointer. A similar problem occurs if the
endpoint has been stopped to cancel a transfer.
