David S. Miller 1f5a7407e4 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says:

====================
1) Introduce skb_to_sgvec_nomark function to add further data to the sg list
   without calling sg_unmark_end first. Needed to add extended sequence
   number informations. From Fan Du.

2) Add IPsec extended sequence numbers support to the Authentication Header
   protocol for ipv4 and ipv6. From Fan Du.

3) Make the IPsec flowcache namespace aware, from Fan Du.

4) Avoid creating temporary SA for every packet when no key manager is
   registered. From Horia Geanta.

5) Support filtering of SA dumps to show only the SAs that match a
   given filter. From Nicolas Dichtel.

6) Remove caching of xfrm_policy_sk_bundles. The cached socket policy bundles
   are never used, instead we create a new cache entry whenever xfrm_lookup()
   is called on a socket policy. Most protocols cache the used routes to the
   socket, so this caching is not needed.

7)  Fix a forgotten SADB_X_EXT_FILTER length check in pfkey, from Nicolas
    Dichtel.

8) Cleanup error handling of xfrm_state_clone.

Nicolas Dichtel d3623099d3 ipsec: add support of limited SA dump
The goal of this patch is to allow userland to dump only a part of SA by
specifying a filter during the dump.
The kernel is in charge to filter SA, this avoids to generate useless netlink
traffic (it save also some cpu cycles). This is particularly useful when there
is a big number of SA set on the system.

Note that I removed the union in struct xfrm_state_walk to fix a problem on arm.
struct netlink_callback->args is defined as a array of 6 long and the first long
is used in xfrm code to flag the cb as initialized. Hence, we must have:
sizeof(struct xfrm_state_walk) <= sizeof(long) * 5.
With the union, it was false on arm (sizeof(struct xfrm_state_walk) was
sizeof(long) * 7), due to the padding.
In fact, whatever the arch is, this union seems useless, there will be always
padding after it. Removing it will not increase the size of this struct (and
reduce it on arm).

This reverts commit 01e219e806.

David Sterba found a different way to provide these features without adding a new
ioctl.  We haven't released any progs with this ioctl yet, so I'm taking this out
for now until we finalize things.

Marc Kleine-Budde says:

====================
this is a pull request of eight patches for net-next/master.

Florian Vaussard contributed a series that merged the sja1000 of_platform
into the platform driver. The of_platform driver is finally removed.
Stephane Grosjean supplied a patch to allocate CANFD skbs. In a patch
by Uwe Kleine-König another missing copyright information was added to
a userspace header. And a patch by Yoann DI RUZZA that adds listen only
mode to the at91_can driver.

Ben Hutchings 6a7a1081ce ethtool: Update documentation of struct ethtool_pauseparam
Convert the inline comments to kernel-doc format.

Explicitly specify that non-zero autoneg is an error if link
autonegotiation is disabled.

Specify that pause capabilities should be advertised dependent on link
autonegotiation, not the autoneg flag here.  There is no way to
opt-out of pause frame autonegotiation, and this improves behaviour
when the link partner is configured to follow pause frame
autonegotiation and our interface is not.

Sudeep Dutt 3b1cc9b962 misc: mic: fix possible signed underflow (undefined behavior) in userspace API
iovcnt is declared as a signed integer in both the userspace API and
as a local variable in mic_virtio.c. The while() loop in mic_virtio.c
iterates until the local variable iovcnt reaches the value 0. If
userspace passes e.g. INT_MIN as iovcnt field, this loop then appears
to depend on an undefined behavior (signed underflow) to complete.
The fix is to use unsigned integers in both the userspace API and
the local variable.
