(a) it does not check whether seed is NULL before using it, resulting in

This patch series adds support for Chelsio Crypto driver.
The patch series has been created against net-next tree and includes
patches for Chelsio Low Level Driver(cxgb4) and adds the new crypto
Upper Layer Driver(chcr) under a new directory drivers/crypto/chelsio.
Patch 1/4 ("cxgb4: Add support for dynamic allocation of resources for
ULD") adds support for dynamic allocation of resources for ULD. The
objective of this patch is to provide generic interface for upper layer
drivers to allocate and initialize hardware resources.
The present cxgb4 (network driver) apart from network functionality, also
initializes hardware and thus acts as lower layer driver for other drivers
to use hardware resources. Thus it acts as both a Low level driver for
Upper layer driver's like iw_cxgb4, cxgb4i and cxgb4it and a Network Driver.
Right now the allocation of resources for Upper layer driver's is done
statically. Patch 1/4 adds a new infrastructure for dynamic allocation of
resources. cxgb4 will read the hardware capability through firmware and
allocate/free the queues for Upper layer drivers when the respective
driver's are loaded and freed when unloaded.
Patch 2/3, 3/4 and 4/4 adds support for Chelsio Crypto Driver. The Crypto
driver will act as another ULD on top of cxgb4.
In this patch series, the ULD API framework is used only by crypto and other
ULD's will make use of it in the next series.
This patch series is only for review, if this looks ok we will test it
thoroughly and send request for merge.
We have included all the maintainers of respective drivers. Kindly
review the changes and provide feedback on the same.
V3: - Removed crypto queues from cxgb4 and added support for dynamic
allocation of resources for Upper layer drivers
- Dependency fix in Kconfig.
V2: - Some residual code cleanup
- Adds pr_fmt with chcr (KBUILD_MODNAME) added
- Changes var name to accomodate them <80 columns in the chcr_register_alg
- Support for printing the crypto queue stats
- Fix compile warnings reported by kbuild bot for certain architectures
- Dependency fix in Kconfig.

tcp: refine tcp_prune_ofo_queue() to not drop all packets
Over the years, TCP BDP has increased a lot, and is typically
in the order of ~10 Mbytes with help of clever Congestion Control
modules.
In presence of packet losses, TCP stores incoming packets into an out of
order queue, and number of skbs sitting there waiting for the missing
packets to be received can match the BDP (~10 Mbytes)
In some cases, TCP needs to make room for incoming skbs, and current
strategy can simply remove all skbs in the out of order queue as a last
resort, incurring a huge penalty, both for receiver and sender.
Unfortunately these 'last resort events' are quite frequent, forcing
sender to send all packets again, stalling the flow and wasting a lot of
resources.
This patch cleans only a part of the out of order queue in order
to meet the memory constraints.

net: sched: avoid duplicates in qdisc dump
tc_dump_qdisc() performs dumping of the per-device qdiscs in two phases;
first, the "standard" dev->qdisc is being dumped. Second, if there is/are
ingress queue(s), they are being dumped as well.
After conversion of netdevice's qdisc linked-list into hashtable, these
two sets are not in two disjunctive sets/lists any more, but are both
"reachable" directly from netdevice's hashtable. As a consequence, the
"full-depth" dump of the ingress qdiscs results in immediately hitting the
netdevice hashtable again, and duplicating the dump that has already been
performed for dev->qdisc.
What in fact needs to be dumped in case of ingress queue is "just" the
top-level ingress qdisc, as everything else has been dumped already.
Fix this by extending tc_dump_qdisc_root() in a way that it can be instructed
whether it should (while performing the "full" per-netdev qdisc dump) perform
the whole recursion, or just dump "additional" top-level (ingress) qdiscs
without performing any kind of recursion.

qdisc_match_from_root() is now iterating over per-netdevice qdisc
hashtable instead of going through a linked-list of qdiscs (independently
on the actual underlying netdev), which was the case before the switch to
hashtable for qdiscs.
For singleton qdiscs, there is no underlying netdev associated though, and
therefore dumping a singleton qdisc will panic, as qdisc_dev(root) will
always be NULL.
Fix this by special-casing singleton qdiscs (those that don't have
underlying netdevice) and introduce immediate handling of those rather
than trying to go over an underlying netdevice. We're in the same
situation in tc_dump_qdisc_root() and tc_dump_tclass_root().
Ultimately, this will have to be slightly reworked so that we are actually
able to show singleton qdiscs (noop) in the dump properly; but we're not
currently doing that anyway, so no regression there, and better do this in

This has the effect that the link, and the sending process, sometimes

when it turns out there is not not enough space in its send queue to

We now change the function link_prepare_wakeup() to use exactly the same

working state while we are still in the process of shutting them down.
This solution works well, but is limited to only work with L2 media, which
is insufficient with the increasing use of UDP as carrier media.
We now replace this solution with a more generic one, by introducing a
new flag "up" in the generic struct tipc_bearer. This field will be set
and reset at the same locations as with the previous solution, while
the packet filtering is moved to the generic code for the sending side.

i40e: remove a stray unlock
We shifted the locking around a bit but forgot to delete this unlock so
now it can unlock twice.

i40e: fix lookup table when RSS disabled/enabled
This patch fixes the bug which causes RSS to continue to work
after being disabled. After disabling RSS, traffic would continue
to be assigned to different queues instead of falling back to a
single queue. Without this patch, attempting to disable RSS would
not work as expected. This patch fixes the bug by clearing the
lookup table used by RSS such that all traffic is assigned to a
single queue. This patch also addresses the issue of reinstating
the lookup table should RSS then be re-enabled.

VF goes through reset path during VF creation which happens to also

avoid wrongly notifying VF reset during VF creation.
Also changing the call order of VF enable, calling it after VF creation
rather than before.

This patch is a fix for the bug i.e. unable to create iwarp device
in VF. This is a sync issue and the iwarp device open is called even
before the PCI register writes are done.
Forcing the PCI register writes to happen just before it exits the
function.

i40e: don't allow reduction of channels below active FD rules
If a driver is unable to maintain all current user supplied settings
from ethtool (or other sources), it is not ok for a user request to
succeed and silently trample over previous configuration.
To that end, if you change the number of channels, it must not be
allowed to reduce the number of channels (queues) below the current
flow director filter rules targets. In this case, return -EINVAL when
a request to reduce the number of channels would do so. In addition
log a warning to the kernel buffer explaining why we failed, and report
the rules which prevent us from lowering the number of channels.

This patch fixes a problem where a static analysis tool generates
a warning for "INVARIANT_CONDITION: Expression 'enabled_tc' used
in the condition always yields the same result."
Without this patch, the driver will not pass the static analysis
tool checks without generating warnings.
This patch fixes the problem by eliminating the irrelevant check
and redundant assignment for the value of enabled_tc.
