Use IP_FREEBIND socket option so that iscsi portal configuration with
explicit IP addresses can happen during boot, before network interfaces
have been assigned IPs.
This is especially important on systemd based Linux boxes where system
boot happens asynchronously and non-trivial configuration must be done
to get targetcli.service to start synchronously after the network is
configured.

This patch fixes a bug in target_submit_cmd() where the failure path
for transport_generic_allocate_tasks() made a direct call to
transport_send_check_condition_and_sense() and not calling the
final target_put_sess_cmd() release callback.
For transport_generic_allocate_tasks() failures, use the proper call to
transport_generic_request_failure() to handle kref_put() along
with potential internal queue full response processing.
It also makes transport_lookup_cmd_lun() failures in
target_submit_cmd() use transport_send_check_condition_and_sense() and
target_put_sess_cmd() directly to avoid se_cmd->se_dev reference in
transport_generic_request_failure() handling.
Finally it drops the out_check_cond: label and use direct reference for
allocate task failures, and per-se_device queue_full handling is
currently not supported for transport_lookup_cmd_lun() failure
descriptors due to se_device dependency.

Retval not very useful, and may even be harmful. Once submitted, fabrics
should expect a sense error if anything goes wrong. All fabrics checking
of this retval are useless or broken:
fc checks it just to emit more debug output.
ib_srpt trickles retval up, then it is ignored.
qla2xxx trickles it up, which then causes a bug because the abort goto
in qla_target.c thinks cmd hasn't been sent to target.
Just returning nothing is best.

WindowsXP+BOT issues a MODE_SENSE request with page 0x1c which is not
suppoerted by target. Target rejects that command with
TCM_INVALID_CDB_FIELD, so far so good. On BOT I can't send the SENSE
response back, instead I can only reply that an error occured. The next
thing happens is a REQUEST_SENSE request with 18 bytes length. Since the
check here is more than 18 bytes I have to NACK that request as well.
This is not really required: We check for some additional room, but we
never use it. The additional length is set to 0xa so the total length is
0xa + 8 = 18 which is fine with my 18 bytes.

It is never correct to use intel_crtc->bpp in intel_dp_link_required,
so instead pass an explicit bpp in to this function. This patch
only supports 18bpp and 24bpp modes, which means that 10bpc modes will
be computed incorrectly. Fixing that will require more extensive
changes, and so must be addressed separately from this bugfix.
intel_dp_link_required is called from intel_dp_mode_valid and
intel_dp_mode_fixup.
* intel_dp_mode_valid is called to list supported modes; in this case,
the current crtc values cannot be relevant as the modes in question
may never be selected. Thus, using intel_crtc->bpp is never right.
* intel_dp_mode_fixup is called during mode setting, but it is run
well before ironlake_crtc_mode_set is called to set intel_crtc->bpp,
so using intel_crtc-bpp in this path can only ever get a stale
value.

mlx4_en_prepare_rx_desc does not correctly clean up after it finds an

it only calls the later.
This bug would prevent a device removal using hotplug after setting the
device MTU to 9000 and opening the network interface. After the fix, we
still see the allocation failure with MTU 9000, but we are able to
remove the device.

After opening the network interface, Mellanox ConnectX device cannot be
removed by hotplug because it has not properly unmapped all DMA memory.
It happens that mlx4_en_activate_rx_rings overrides the variable that
keeps the size of the memory mapped.
This is fixed by passing to mlx4_en_destroy_rx_ring the same size that is
given to mlx4_en_create_rx_ring.
After applying this patch, hot unplugging the device works after opening

commit adb5066 "ath9k_hw: do not apply the 2.4 ghz ack timeout
workaround to cts" reduced the hardware CTS timeout to the normal

need the same extra time that it needs for the ACK timeout, it
does need more than the value specified in the standard, but only
for 2.4 GHz.
This patch brings the CTS timeout value in sync with the initialization
values, while still allowing adjustment for bigger distances.

commit b4a82a0 "ath9k_hw: fix interpretation of the rx KeyMiss flag"
fixed the interpretation of the KeyMiss flag for keycache based lookups,
however WEP encryption uses a static index, so KeyMiss is always asserted
for it, even though frames are decrypted properly.
Fix this by clearing the ATH9K_RXERR_KEYMISS flag if no keycache based

Currently even if association is failed "iw link" shows some
information about connected BSS and "Tx timeout" error is seen in
dmesg log.
This patch fixes below issues in the code to handle assoc failure
case correctly.
1) "status" variable in mwifiex_wait_queue_complete() is not
correctly updated. Hence driver doesn't inform cfg80211 stack
about association failure.
2) During association network queues are stopped but carrier is
not cleared, which gives Tx timeout error in failure case

KDFONTOP(GET) currently fails with EIO when being run in a 32bit userland
with a 64bit kernel if the font width is not 8.
This is because the compatibility layer introduced by e9216651 ("tty:
handle VT specific compat ioctls in vt driver") forces the addition of the
KD_FONT_FLAG_OLD flag, which makes con_font_get return EIO in such case.
This flag should *not* be set for KDFONTOP, since it's actually the whole
point of this flag (see comment in con_font_set for instance).

The rbd_client structure uses a kref to arrange for cleaning up and
freeing an instance when its last reference is dropped. The cleanup
routine is rbd_client_release(), and one of the things it does is
delete the rbd_client from rbd_client_list. It acquires node_lock
to do so, but the way it is done is still not safe.
The problem is that when attempting to reuse an existing rbd_client,
the structure found might already be in the process of getting
destroyed and cleaned up.
Here's the scenario, with "CLIENT" representing an existing
rbd_client that's involved in the race:
Thread on CPU A | Thread on CPU B
--------------- | ---------------
rbd_put_client(CLIENT) | rbd_get_client()
kref_put() | (acquires node_lock)
kref->refcount becomes 0 | __rbd_client_find() returns CLIENT
calls rbd_client_release() | kref_get(&CLIENT->kref);
| (releases node_lock)
(acquires node_lock) |
deletes CLIENT from list | ...and starts using CLIENT...
(releases node_lock) |
and frees CLIENT | <-- but CLIENT gets freed here
Fix this by having rbd_put_client() acquire node_lock. The result
could still be improved, but at least it avoids this problem.

The pci-quirks.c is enabled for all vendors and devices, and is
enabled if USB and PCI are configured.

Evergreen and NI blit copy was broken if the buffer maps to a rectangle
whose one dimension is 16384 (max dimension allowed by these chips).
In the mainline kernel, the problem is exposed only when buffers are
very large (1G), but it's still a problem. The problem could be exposed
for smaller buffers if anyone modifies the algorithm for rectangle
construction in r600_blit_create_rect() (the reason why someone would
modify that algorithm is to tune the performance of buffer moves).
The root cause was in i2f() function which only operated on range between
0 and 16383. Fix this by extending the range of i2f() function to 0 to
32767.
While at it improve the function so that the range can be easily
extended in the future (if it becomes necessary), cleanup lines
over 80 characters, and replace in-line comments with one strategic
comment that explains the crux of the function.
Credits to michel@daenzer.net for pointing out the root cause of
the bug.

In my AMPDU rework, I rely on the sequence numbers of frames. But
I didn't check that the frame has a valid tid before updating the
tracking counters. As a result, the Tx queues were stalled. People
who hit this bug saw that we simply didn't let any data out.
This bug was introduced in 3.3.
This patch fixes that and checks that the frame is a QoS frame before
looking at its tid and changing the counters.

This patch correct the type of variables containing the rssi
values read from the rxwi.
In function rt2800_agc_to_rssi() 3 variables (rssi0, rssi1, rss2)
defined as int was assigned a 16bit signed values as unsigned.
From a test with a hi-gain antenna I verified that the rxwi
contains signed rssi values in the range -13/+81 (inclusive)
with 0 as an error condition. In case of negative values a
condition is triggered and the function return -128dBm while
the signal is at its maximum. This patch correct the cast so
negative values are not treated as very high positive values
(ex. -13 does not become 243).

The value of this register is transferred to the V_COUNTER register at the
beginning of vertical blank. V_COUNTER is the reference for VLINE waits and
goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout,
so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the
beginning of vertical blank, and VLINE waits excluding the whole scanout area
could never finish (possibly only if VIEWPORT_Y_START is larger than the length
of vertical blank in scanlines). Setting DESKTOP_HEIGHT to the framebuffer
height should prevent this for any kind of VLINE wait.

In the current code, vendor-specific MADs (e.g with the FDR-10
attribute) are silently dropped by the driver, resulting in timeouts
at the sending side and inability to query/configure the relevant
feature. However, the ConnectX firmware is able to handle such MADs.
For unsupported attributes, the firmware returns a GET_RESPONSE MAD
containing an error status.
For example, for a FDR-10 node with LID 11:
# ibstat mlx4_0 1
CA: 'mlx4_0'
Port 1:
State: Active
Physical state: LinkUp
Rate: 40 (FDR10)
Base lid: 11
LMC: 0
SM lid: 24
Capability mask: 0x02514868
Port GUID: 0x0002c903002e65d1
Link layer: InfiniBand
Extended Port Query (EPI) vendor mad timeouts before the patch:
# smpquery MEPI 11 -d
ibwarn: [4196] smp_query_via: attr 0xff90 mod 0x0 route Lid 11
ibwarn: [4196] _do_madrpc: retry 1 (timeout 1000 ms)
ibwarn: [4196] _do_madrpc: retry 2 (timeout 1000 ms)
ibwarn: [4196] _do_madrpc: timeout after 3 retries, 3000 ms
ibwarn: [4196] mad_rpc: _do_madrpc failed; dport (Lid 11)
smpquery: iberror: [pid 4196] main: failed: operation EPI: ext port info query failed
EPI query works OK with the patch:
# smpquery MEPI 11 -d

ibwarn: [6548] mad_rpc: data offs 64 sz 64

The life cycle of a device-mapper target is:
1) create
2) resume
3) suspend
*) possibly repeat from 2
4) destroy
The dm-raid target is unconditionally calling MD's bitmap_load function upon
every resume. If steps 2 & 3 above are repeated, bitmap_load is called
multiple times. It is only written to be called once; otherwise, it allocates
new memory for the bitmap (without freeing the old) and incrementing the number
of pages it thinks it has without zeroing first. This ultimately leads to
access beyond allocated memory and lost memory.
Simply avoiding the bitmap_load call upon resume is not sufficient. If the
target was suspended while the initial recovery was only partially complete,
it needs to be restarted when the target is resumed. This is why
'md_wakeup_thread' is called before issuing the 'mddev_resume'.

1) Setting link attributes can modify the size of the attributes that
would be reported on a subsequent getlink netlink operation,
therefore min_ifinfo_dump_size needs to be adjusted. From Stefan
Gula.
2) Resegmentation of TSO frames while trimming can violate invariants
expected by callers, namely that the number of segments can only stay
the same or decrease, never increase. If MSS changes, however, we
can trim data but then end up with more segments. Fix this by only
segmenting to the MSS already recorded in the SKB. That's the
simplest fix for now and if we want to get more fancy in the future
that's a more involved change.

Error handling in msm_iommu_unmap() is broken. On some error
conditions retval is set to a non-zero value which causes
the function to return 'len' at the end. This hides the
error from the user. Zero should be returned in those error
cases.

The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.

Properly set the parent device of i2c buses before registering them so
that they will show at the right place in the device tree (rather than
in /sys/devices directly.)

In particular, I found I was hitting the max-file limit in the VFS,
and the EFILE was being magically transformed into ENOMEM. Confusion
reigns.

This reverts commit 87499ffdcb.
Where is that paper bag ... ah here.
I've failed to take an odd interaction between my other cleanups and
this reclaim_buffers patch into account and also failed to properly
test it. Looks like there are more dragons and hidden trapdoors in the
drm release path than actual lines of code.
Until I get a clue, let's just revert this.

This otg driver depends on marvell EHCI driver, so add the dependence.
It can fix the following build error on i386:
ERROR: "usb_remove_hcd" [drivers/usb/otg/mv_otg.ko] undefined!
ERROR: "usb_add_hcd" [drivers/usb/otg/mv_otg.ko] undefined!

ab943a2e12 (USB: gadget: gadget zero uses new suspend/resume hooks)
introduced a copy-paste error where f_loopback.c writes to a variable
declared in f_sourcesink.c. This prevents one from creating gadgets
that only have a loopback function.
