Commit
12a8541d5c82 "bnx2x: Delay during kdump load" added a 5 seconds

realize the old driver is gone.
The problem with the delay is that it is per-device, so if you have
several bnx2x NICs in NPAR mode, the delays can accumulate to minutes.
Fix it by adjusting the delay so that we do not wait more than

ARM: net: delegate filter to kernel interpreter when imm_offset() return value can't fit into 12bits.
The ARM JIT code emits "ldr rX, [pc, #offset]" to access the literal
pool. #offset maximum value is 4095 and if the generated code is too
large, the #offset value can overflow and not point to the expected
slot in the literal pool. Additionally, when overflow occurs, bits of
the overflow can end up changing the destination register of the ldr
instruction.
Fix that by detecting the overflow in imm_offset() and setting a flag
that is checked for each BPF instructions converted in
build_body(). As of now it can only be detected in the second pass. As
a result the second build_body() call can now fail, so add the
corresponding cleanup code in that case.
Using multiple literal pools in the JITed code is going to require
lots of intrusive changes to the JIT code (which would better be done
as a feature instead of fix), just delegating to the kernel BPF
interpreter in that case is a more straight forward, minimal fix and
easy to backport.

net/rds: RDS-TCP robustness fixes
This patch-set contains bug fixes for state-recovery at the RDS
layer when the underlying transport is TCP and the TCP state at one
of the endpoints is reset
V2 changes: DaveM comments to reduce memory footprint, follow
NFS/RPC model where possible. Added test-case #3
Without the changes in this set, when one of the endpoints is reset,
the existing code does not correctly clean up RDS socket state for stale
connections, resulting in some unstable, timing-dependant behavior on
the wire, including an infinite exchange of 3WHs back-and-forth, and a
resulting potential to never converge RDS state.
Test cases used to verify the changes in this set are:
1. Start rds client/server applications on two participating nodes,
node1 and node2. After at least one packet has been sent (to establish
the TCP connection), restart the rds_tcp module on the client, and
now resend packets. Tcpdump should show server sending a FIN for the
"old" client port, and clean connection establishment/exchange for
the new client port.
2. At the end of step 1, restart rds srever on node2, and start client on
node1, make sure using tcpdump, 'netstat -an|grep 16385' that
packets flow correctly.
3. start RDS client/server application on two participating nodes, and
repeat steps 1 and 2, but this time, simulate node failure by doing
"ifconfig <intf> down", so no FIN is sent.

net/rds: RDS-TCP: Always create a new rds_sock for an incoming connection.
When running RDS over TCP, the active (client) side connects to the
listening ("passive") side at the RDS_TCP_PORT. After the connection
is established, if the client side reboots (potentially without even
sending a FIN) the server still has a TCP socket in the esablished
state. If the server-side now gets a new SYN comes from the client
with a different client port, TCP will create a new socket-pair, but
the RDS layer will incorrectly pull up the old rds_connection (which
is still associated with the stale t_sock and RDS socket state).
This patch corrects this behavior by having rds_tcp_accept_one()
always create a new connection for an incoming TCP SYN.
The rds and tcp state associated with the old socket-pair is cleaned
up via the rds_tcp_state_change() callback which would typically be
invoked in most cases when the client-TCP sends a FIN on TCP restart,
triggering a transition to CLOSE_WAIT state. In the rarer event of client
death without a FIN, TCP_KEEPALIVE probes on the socket will detect
the stale socket, and the TCP transition to CLOSE state will trigger
the RDS state cleanup.

net/smsc911x: fix irq resource allocation failure
When smsc911x uses GPIO as the interrupt controller, and if both are
loaded as modules, we get following error:
"smsc911x: Could not allocate irq resource"
This issue is because of smsc911x using platform_get_resource to get
device tree based irq resource.
commit "
9ec36ca (of/irq: do irq resolution in platform_get_irq)" and
commit "7085a7 (drivers: platform: parse IRQ flags from resources)" add
support in platform_get_irq to resolve irq and irq_flags respectively
for both modern device tree and legacy static platform data platforms.
Modify smsc911x driver to use platform_get_irq to pick up irq resource
correctly and use irq_get_trigger_type to get the IRQ trigger flags.

net: core: Correct an over-stringent device loop detection.
The code in __netdev_upper_dev_link() has an over-stringent
loop detection logic that actually prevents valid configurations
from working correctly.
In particular, the logic returns an error if an upper device
is already in the list of all upper devices for a given dev.
This particular check seems to be a overzealous as it disallows
perfectly valid configurations. For example:
# ip l a link eth0 name eth0.10 type vlan id 10
# ip l a dev br0 typ bridge
# ip l s eth0.10 master br0
# ip l s eth0 master br0 <--- Will fail
If you switch the last two commands (add eth0 first), then both
will succeed. If after that, you remove eth0 and try to re-add
it, it will fail!
It appears to be enough to simply check adj_list to keeps things
safe.
I've tried stacking multiple devices multiple times in all different
combinations, and either rx_handler registration prevented the stacking
of the device linking cought the error.

That patch is solving a non-existant problem while creating a

When we unhash it the name space must be the same as the one
we had when we hashed it. So this patch is completely bogus

rdma_conn_param private data is copied using memcpy after headers such
as cma_hdr (see cma_resolve_ib_udp as example). so the start of the
private data is aligned to the end of the structure that come before. if
this structure end with u32 the meaning is that the start of the private

naturally aligned but in case the structure start is not 8 bytes aligned,
all u64 members of this structure will not be aligned. to solve this issue
we must use special macros that allow unaligned access to those
unaligned members.

net/mlx4_en: Schedule napi when RX buffers allocation fails
When system is out of memory, refilling of RX buffers fails while
the driver continue to pass the received packets to the kernel stack.
At some point, when all RX buffers deplete, driver may fall into a
sleep, and not recover when memory for new RX buffers is once again
availible. This is because hardware does not have valid descriptors,
so no interrupt will be generated for the driver to return to work
in napi context. Fix it by schedule the napi poll function from
stats_task delayed workqueue, as long as the allocations fail.

dm: fix free_rq_clone() NULL pointer when requeueing unmapped request
Commit
022333427a ("dm: optimize dm_mq_queue_rq to _not_ use kthread if
using pure blk-mq") mistakenly removed free_rq_clone()'s clone->q check
before testing clone->q->mq_ops. It was an oversight to discontinue
that check for 1 of the 2 use-cases for free_rq_clone():
1) free_rq_clone() called when an unmapped original request is requeued
2) free_rq_clone() called in the request-based IO completion path
The clone->q check made sense for case #1 but not for #2. However, we
cannot just reinstate the check as it'd mask a serious bug in the IO
completion case #2 -- no in-flight request should have an uninitialized
request_queue (basic block layer refcounting _should_ ensure this).
The NULL pointer seen for case #1 is detailed here:
https://www.redhat.com/archives/dm-devel/2015-April/msg00160.html
Fix this free_rq_clone() NULL pointer by simply checking if the
mapped_device's type is DM_TYPE_MQ_REQUEST_BASED (clone's queue is
blk-mq) rather than checking clone->q->mq_ops. This avoids the need to
dereference clone->q, but a WARN_ON_ONCE is added to let us know if an
uninitialized clone request is being completed.

Commit
bfebd1cdb4 ("dm: add full blk-mq support to request-based DM")
didn't properly account for the need to short-circuit re-initializing

Otherwise, reloading a blk-mq request-based DM table (either manually
or via multipathd) resulted in errors, see:
https://www.redhat.com/archives/dm-devel/2015-April/msg00132.html
Fix is to only initialize the request_queue on the initial table load
(when the mapped_device type is assigned).
This is better than having dm_init_request_based_blk_mq_queue() return
early if the queue was already initialized because it elevates the
constraint to a more meaningful location in DM core. As such the
pre-existing early return in dm_init_request_based_queue() can now be
removed.
