Pull networking fixes from David Miller:
1) Need to save away the IV across tls async operations, from Dave
Watson.
2) Upon successful packet processing, we should liberate the SKB with
dev_consume_skb{_irq}(). From Yang Wei.
3) Only apply RX hang workaround on effected macb chips, from Harini
Katakam.
4) Dummy netdev need a proper namespace assigned to them, from Josh
Elsasser.
5) Some paths of nft_compat run lockless now, and thus we need to use a
proper refcnt_t. From Florian Westphal.
6) Avoid deadlock in mlx5 by doing IRQ locking, from Moni Shoua.
7) netrom does not refcount sockets properly wrt. timers, fix that by
using the sock timer API. From Cong Wang.
8) Fix locking of inexact inserts of xfrm policies, from Florian
Westphal.
9) Missing xfrm hash generation bump, also from Florian.
10) Missing of_node_put() in hns driver, from Yonglong Liu.
11) Fix DN_IFREQ_SIZE, from Johannes Berg.
12) ip6mr notifier is invoked during traversal of wrong table, from Nir
Dotan.
13) TX promisc settings not performed correctly in qed, from Manish
Chopra.
14) Fix OOB access in vhost, from Jason Wang.

Add multiple people as maintainers for XDP, sorted alphabetically.
XDP is also tied to driver level support and code, but we cannot add all
drivers to the list. Instead K: and N: match on 'xdp' in hope to catch some
of those changes in drivers.

One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
instance = kvzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

The skb should be freed by dev_consume_skb_any() in b44_start_xmit()
when bounce_skb is used. The skb is be replaced by bounce_skb, so the
original skb should be consumed(not drop).

The interrupt handler contains a workaround for RX hang applicable
to Zynq and AT91RM9200 only. Subsequent versions do not need this
workaround. This workaround unnecessarily resets RX whenever RX used
bit read is observed, which can be often under heavy traffic. There
is no other action performed on RX UBR interrupt. Hence introduce a
CAPS mask; enable this interrupt and workaround only on affected
versions.

If there are outstanding async tx requests (when crypto returns EINPROGRESS),
there is a potential deadlock: the tx work acquires the lock, while we

aead_request_set_crypt takes an iv pointer, and we change the iv
soon after setting it. Some async crypto algorithms don't save the iv,
so we need to save it in the tls_rec for async requests.
Found by hardcoding x64 aesni to use async crypto manager (to test the async
codepath), however I don't think this combination can happen in the wild.
Presumably other hardware offloads will need this fix, but there have been
no user reports.

After batched used ring updating was introduced in commit e2b3b35eb989
("vhost_net: batch used ring update in rx"). We tend to batch heads in
vq->heads for more than one packet. But the quota passed to
get_rx_bufs() was not correctly limited, which can result a OOB write
in vq->heads.
headcount = get_rx_bufs(vq, vq->heads + nvq->done_idx,
vhost_len, &in, vq_log, &log,
likely(mergeable) ? UIO_MAXIOV : 1);
UIO_MAXIOV was still used which is wrong since we could have batched
used in vq->heads, this will cause OOB if the next buffer needs more
than 960 (1024 (UIO_MAXIOV) - 64 (VHOST_NET_BATCH)) heads after we've
batched 64 (VHOST_NET_BATCH) heads:

pull-request: bpf-next 2019-01-29
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Teach verifier dead code removal, this also allows for optimizing /
removing conditional branches around dead code and to shrink the
resulting image. Code store constrained architectures like nfp would
have hard time doing this at JIT level, from Jakub.
2) Add JMP32 instructions to BPF ISA in order to allow for optimizing
code generation for 32-bit sub-registers. Evaluation shows that this
can result in code reduction of ~5-20% compared to 64 bit-only code
generation. Also add implementation for most JITs, from Jiong.
3) Add support for __int128 types in BTF which is also needed for
vmlinux's BTF conversion to work, from Yonghong.
4) Add a new command to bpftool in order to dump a list of BPF-related
parameters from the system or for a specific network device e.g. in
terms of available prog/map types or helper functions, from Quentin.
5) Add AF_XDP sock_diag interface for querying sockets from user
space which provides information about the RX/TX/fill/completion
rings, umem, memory usage etc, from Björn.
6) Add skb context access for skb_shared_info->gso_segs field, from Eric.
7) Add support for testing flow dissector BPF programs by extending
existing BPF_PROG_TEST_RUN infrastructure, from Stanislav.
8) Split BPF kselftest's test_verifier into various subgroups of tests
in order better deal with merge conflicts in this area, from Jakub.
9) Add support for queue/stack manipulations in bpftool, from Stanislav.
10) Document BTF, from Yonghong.
11) Dump supported ELF section names in libbpf on program load
failure, from Taeung.
12) Silence a false positive compiler warning in verifier's BTF
handling, from Peter.
13) Fix help string in bpftool's feature probing, from Prashant.
14) Remove duplicate includes in BPF kselftests, from Yue.

Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next tree:
1) Introduce a hashtable to speed up object lookups, from Florian Westphal.
2) Make direct calls to built-in extension, also from Florian.
3) Call helper before confirming the conntrack as it used to be originally,
from Florian.
4) Call request_module() to autoload br_netfilter when physdev is used
to relax the dependency, also from Florian.
5) Allow to insert rules at a given position ID that is internal to the
batch, from Phil Sutter.
6) Several patches to replace conntrack indirections by direct calls,
and to reduce modularization, from Florian. This also includes
several follow up patches to deal with minor fallout from this
rework.
7) Use RCU from conntrack gre helper, from Florian.
8) GRE conntrack module becomes built-in into nf_conntrack, from Florian.
9) Replace nf_ct_invert_tuplepr() by calls to nf_ct_invert_tuple(),
from Florian.
10) Unify sysctl handling at the core of nf_conntrack, from Florian.
11) Provide modparam to register conntrack hooks.
12) Allow to match on the interface kind string, from wenxu.
13) Remove several exported symbols, not required anymore now after
a bit of de-modulatization work has been done, from Florian.
14) Remove built-in map support in the hash extension, this can be
done with the existing userspace infrastructure, from laura.
15) Remove indirection to calculate checksums in IPVS, from Matteo Croce.
16) Use call wrappers for indirection in IPVS, also from Matteo.
17) Remove superfluous __percpu parameter in nft_counter, patch from
Luc Van Oostenryck.

====================
This patch series adds support for testing flow dissector BPF programs
by extending already existing BPF_PROG_TEST_RUN. The goal is to have
a packet as an input and `struct bpf_flow_key' as an output. That way
we can easily test flow dissector programs' behavior. I've also modified
existing test_progs.c test to do a simple flow dissector run as well.
* first patch introduces new __skb_flow_bpf_dissect to simplify
sharing between __skb_flow_bpf_dissect and BPF_PROG_TEST_RUN
* second patch adds actual BPF_PROG_TEST_RUN support
* third patch adds example usage to the selftests
v3:
* rebased on top of latest bpf-next
v2:
* loop over 'kattr->test.repeat' inside of
bpf_prog_test_run_flow_dissector, don't reuse
bpf_test_run/bpf_test_run_one

When prog array is updated with bpftool users often refer
to the map via the ID. Unfortunately, that's likely
to lead to confusion because prog arrays get flushed when
the last user reference is gone. If there is no other
reference bpftool will create one, update successfully
just to close the map again and have it flushed.
Warn about this case in non-JSON mode.
If the problem continues causing confusion we can remove
the support for referring to a map by ID for prog array
update completely. For now it seems like the potential
inconvenience to users who know what they're doing outweighs
the benefit.

Cache number of fragments in the skb locally as in case
of linear skb (with zero fragments), tx completion
(or freeing of skb) may happen before driver tries
to get number of frgaments from the skb which could
lead to stale access to an already freed skb.

VFs may hit VF-PF channel timeout while probing, as in some
cases it was observed that VF FLR and VF "acquire" message
transaction (i.e first message from VF to PF in VF's probe flow)
could occur simultaneously which could lead VF to fail sending
"acquire" message to PF as VF is marked disabled from HW perspective
due to FLR, which will result into channel timeout and VF probe failure.
In such cases, try retrying VF "acquire" message so that in later
attempts it could be successful to pass message to PF after the VF
FLR is completed and can be probed successfully.

VF is always configured to drop control frames
(with reserved mac addresses) but to work LACP
on the VFs, it would require LACP control frames
to be forwarded or transmitted successfully.
This patch fixes this in such a way that trusted VFs
(marked through ndo_set_vf_trust) would be allowed to
pass the control frames such as LACP pdus.

When running tx switched traffic between VNICs
created via a bridge(to which VFs are added),
adapter drops the unicast packets in tx flow due to
VNIC's ucast mac being unknown to it. But VF interfaces
being in promiscuous mode should have caused adapter
to accept all the unknown ucast packets. Later, it
was found that driver doesn't really configure tx
promiscuous mode settings to accept all unknown unicast macs.
This patch fixes tx promiscuous mode settings to accept all
unknown/unmatched unicast macs and works out the scenario.

====================
qed*: Error recovery process
Parity errors might happen in the device's memories due to momentary bit
flips which are caused by radiation.
Errors that are not correctable initiate a process kill event, which blocks
the device access towards the host and the network, and a recovery process
is started in the management FW and in the driver.
This series adds the support of this process in the qed core module and in
the qede driver (patches 2 & 3).
Patch 1 in the series revises the load sequence, to avoid PCI errors that
might be observed during a recovery process.
Changes in v2:
- Addressed issue found in https://patchwork.ozlabs.org/patch/1030545/
The change was done be removing the enum and passing a boolean to
the related functions.

This patch adds the error recovery process in the qede driver.
The process includes a partial/customized driver unload and load, which
allows it to look like a short suspend period to the kernel while
preserving the net devices' state.

This patch adds the detection and handling of a parity error ("process kill
event"), including the update of the protocol drivers, and the prevention
of any HW access that will lead to device access towards the host while
recovery is in progress.
It also provides the means for the protocol drivers to trigger a recovery
process on their decision.

Initiating final cleanup after an ungraceful driver unload can lead to bad
PCI accesses towards the host.
This patch revises the load sequence so final cleanup is sent while the
internal master enable is cleared, to prevent the host accesses, and clears
the internal error indications just before enabling the internal master
enable.

====================
Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for your net tree:
1) The nftnl mutex is now per-netns, therefore use reference counter
for matches and targets to deal with concurrent updates from netns.
Moreover, place extensions in a pernet list. Patches from Florian Westphal.
2) Bail out with EINVAL in case of negative timeouts via setsockopt()
through ip_vs_set_timeout(), from ZhangXiaoxu.
3) Spurious EINVAL on ebtables 32bit binary with 64bit kernel, also
from Florian.
4) Reset TCP option header parser in case of fingerprint mismatch,
otherwise follow up overlapping fingerprint definitions including
TCP options do not work, from Fernando Fernandez Mancera.
5) Compilation warning in ipt_CLUSTER with CONFIG_PROC_FS unset.
From Anders Roxell.
