3f96a53211 net: sctp: rfc4443: do not report ICMP redirects to user space
Adapt the same behaviour for SCTP as present in TCP for ICMP redirect
messages. For IPv6, RFC4443, section 2.4. says:

  ...
  (e) An ICMPv6 error message MUST NOT be originated as a result of
      receiving the following:
  ...
       (e.2) An ICMPv6 redirect message [IPv6-DISC].
  ...

Therefore, do not report an error to user space, just invoke dst's redirect
callback and leave, same for IPv4 as done in TCP as well. The implication
w/o having this patch could be that the reception of such packets would
generate a poll notification and in worst case it could even tear down the
whole connection. Therefore, stop updating sk_err on redirects.

9900303ec7 bgmac: implement unaligned addressing for DMA rings that support it
This is important patch for new devices that support unaligned
addressing. That devices suffer from the backward-compatibility bug in
DMA engine. In theory we should be able to use old mechanism, but in
practice DMA address seems to be randomly copied into status register
when hardware reaches end of a ring. This breaks reading slot number
from status register and we can't use DMA anymore.

6a391e7bf2 bgmac: fix internal switch initialization
Some devices (BCM4749, BCM5357, BCM53572) have internal switch that
requires initialization. We already have code for this, but because
of the typo in code it was never working. This resulted in network not
working for some routers and possibility of soft-bricking them.

Use correct bit for switch initialization and fix typo in the define.

116cc02253 vfs: don't set FILE_CREATED before calling ->atomic_open()
If O_CREAT|O_EXCL are passed to open, then we know that either

 - the file is successfully created, or
 - the operation fails in some way.

So previously we set FILE_CREATED before calling ->atomic_open() so the
filesystem doesn't have to.  This, however, led to bugs in the
implementation that went unnoticed when the filesystem didn't check for
existence, yet returned success.  To prevent this kind of bug, require
filesystems to always explicitly set FILE_CREATED on O_CREAT|O_EXCL and
verify this in the VFS.

Also added a couple more verifications for the result of atomic_open():

 - Warn if filesystem set FILE_CREATED despite the lack of O_CREAT.
 - Warn if filesystem set FILE_CREATED but gave a negative dentry.

01c919abaf nfs: set FILE_CREATED
Set FILE_CREATED on O_CREAT|O_EXCL.  If the NFS server honored our request
for exclusivity then this must be correct.

Currently this is a no-op, since the VFS sets FILE_CREATED anyway.  The
next patch will, however, require this flag to be always set by
filesystems.

2cf55125c6 netfilter: ipset: Fix serious failure in CIDR tracking
This fixes a serious bug affecting all hash types with a net element -
specifically, if a CIDR value is deleted such that none of the same size
exist any more, all larger (less-specific) values will then fail to
match. Adding back any prefix with a CIDR equal to or more specific than
the one deleted will fix it.

Steps to reproduce:
ipset -N test hash:net
ipset -A test 1.1.0.0/16
ipset -A test 2.2.2.0/24
ipset -T test 1.1.1.1           #1.1.1.1 IS in set
ipset -D test 2.2.2.0/24
ipset -T test 1.1.1.1           #1.1.1.1 IS NOT in set

This is due to the fact that the nets counter was unconditionally
decremented prior to the iteration that shifts up the entries. Now, we
first check if there is a proceeding entry and if not, decrement it and
return. Otherwise, we proceed to iterate and then zero the last element,
which, in most cases, will already be zero.

0f1799ba1a netfilter: ipset: Consistent userspace testing with nomatch flag
The "nomatch" commandline flag should invert the matching at testing,
similarly to the --return-nomatch flag of the "set" match of iptables.
Until now it worked with the elements with "nomatch" flag only. From
now on it works with elements without the flag too, i.e:

 # ipset n test hash:net
 # ipset a test 10.0.0.0/24 nomatch
 # ipset t test 10.0.0.1
 10.0.0.1 is NOT in set test.
 # ipset t test 10.0.0.1 nomatch
 10.0.0.1 is in set test.

 # ipset a test 192.168.0.0/24
 # ipset t test 192.168.0.1
 192.168.0.1 is in set test.
 # ipset t test 192.168.0.1 nomatch
 192.168.0.1 is NOT in set test.

 Before the patch the results were

 ...
 # ipset t test 192.168.0.1
 192.168.0.1 is in set test.
 # ipset t test 192.168.0.1 nomatch
 192.168.0.1 is in set test.

7de8fe2fa8 pstore: Adjust buffer size for compression for smaller registered buffers
When backends (ex: efivars) have smaller registered buffers, the
big_oops_buf is too big for them as number of repeated occurences
in the text captured will be less. What happens is that pstore takes
too big a bite from the dmesg log and then finds it cannot compress it
enough to meet the backend block size. Patch takes care of adjusting
the buffer size based on the registered buffer size. cmpr values have
been arrived after doing experiments with plain text for buffers of
size 1k - 4k (Smaller the buffer size repeated occurence will be less)
and with sample crash log for buffers ranging from 4k - 10k.

Now that DRM_EXYNOS depends on OF, we do not need individual

13b62e46d5 sched: Fix comment for sched_info_depart
sched_info_depart seems to be only called from
sched_info_switch(), so only on involuntary task switch.

Fix the comment to match.

73a695f857 cxgb4: remove workqueue when driver registration fails
When driver registration fails, we need to clean up the resources allocated
before. cxgb4 missed to destroy the workqueue allocated at the very beginning.

This patch destroies the workqueue when registration fails.

7eacd03810 bonding: Make alb learning packet interval configurable
running bonding in ALB mode requires that learning packets be sent periodically,
so that the switch knows where to send responding traffic.  However, depending
on switch configuration, there may not be any need to send traffic at the
default rate of 3 packets per second, which represents little more than wasted
data.  Allow the ALB learning packet interval to be made configurable via sysfs

35e4237973 vxlan: Fix sparse warnings
This patch fixes sparse warnings when incorrectly handling the port number
and using int instead of unsigned int iterating through &vn->sock_list[].
Keeping the port as __be16 also makes things clearer wrt endianess.
Also, it was pointed out that vxlan_get_rx_port() had unnecessary checks
which got removed.

716ec052d2 bridge: fix NULL pointer deref of br_port_get_rcu
The NULL deref happens when br_handle_frame is called between these
2 lines of del_nbp:
	dev->priv_flags &= ~IFF_BRIDGE_PORT;
	/* --> br_handle_frame is called at this time */
	netdev_rx_handler_unregister(dev);

In br_handle_frame the return of br_port_get_rcu(dev) is dereferenced
without check but br_port_get_rcu(dev) returns NULL if:
	!(dev->priv_flags & IFF_BRIDGE_PORT)

Eric Dumazet pointed out the testing of IFF_BRIDGE_PORT is not necessary
here since we're in rcu_read_lock and we have synchronize_net() in
netdev_rx_handler_unregister. So remove the testing of IFF_BRIDGE_PORT
and by the previous patch, make sure br_port_get_rcu is called in
bridging code.
