l2tp: rely on ppp layer for skb scrubbing
Since 79c441ae505c ("ppp: implement x-netns support"), the PPP layer
calls skb_scrub_packet() whenever the skb is received on the PPP

redundant.

The current code only supports an rx/tx ring pair for each completion ring.
This patch series add support for using a dedicated completion ring for

The benefits for using dedicated completion rings are:
1. A burst of rx packets can cause delay in processing tx events if the

delay in re-starting the tx queue.
2. A completion ring is sized according to the rx and tx ring size rounded

sized by adding the rx and tx ring sizes and then rounded to the next power

sctp: sctp should release assoc when sctp_make_abort_user return NULL in sctp_close
In sctp_close, sctp_make_abort_user may return NULL because of memory
allocation failure. If this happens, it will bypass any state change
and never free the assoc. The assoc has no chance to be freed and it
will be kept in memory with the state it had even after the socket is
closed by sctp_close().
So if sctp_make_abort_user fails to allocate memory, we should abort
the asoc via sctp_primitive_ABORT as well. Just like the annotation in
sctp_sf_cookie_wait_prm_abort and sctp_sf_do_9_1_prm_abort said,
"Even if we can't send the ABORT due to low memory delete the TCB.
This is a departure from our typical NOMEM handling".
But then the chunk is NULL (low memory) and the SCTP_CMD_REPLY cmd would
dereference the chunk pointer, and system crash. So we should add
SCTP_CMD_REPLY cmd only when the chunk is not NULL, just like other
places where it adds SCTP_CMD_REPLY cmd.

net, socket, socket_wq: fix missing initialization of flags
Commit ceb5d58b2170 ("net: fix sock_wake_async() rcu protection") from
the current 4.4 release cycle introduced a new flags member in
struct socket_wq and moved SOCKWQ_ASYNC_NOSPACE and SOCKWQ_ASYNC_WAITDATA
from struct socket's flags member into that new place.
Unfortunately, the new flags field is never initialized properly, at least
not for the struct socket_wq instance created in sock_alloc_inode().
One particular issue I encountered because of this is that my GNU Emacs
failed to draw anything on my desktop -- i.e. what I got is a transparent
window, including the title bar. Bisection lead to the commit mentioned
above and further investigation by means of strace told me that Emacs
is indeed speaking to my Xorg through an O_ASYNC AF_UNIX socket. This is
reproducible 100% of times and the fact that properly initializing the
struct socket_wq ->flags fixes the issue leads me to the conclusion that
somehow SOCKWQ_ASYNC_WAITDATA got set in the uninitialized ->flags,
preventing my Emacs from receiving any SIGIO's due to data becoming
available and it got stuck.
Make sock_alloc_inode() set the newly created struct socket_wq's ->flags
member to zero.

====================
10GbE Intel Wired LAN Driver Updates 2015-12-29
This series contains updates to ixgbe and ixgbevf.
William Dauchy provides a fix for ixgbevf that was implemented for ixgbe,
commit 5d6002b7b822c7 ("ixgbe: Fix handling of NAPI budget when multiple
queues are enabled per vector"). The issue was that the polling routine
would increase the budget for receive to at least 1 per queue if multiple
queues were present, which resulted in receive packets being processed
when the budget was 0.
Emil provides minor cleanups for ixgbevf, one being that we need to
check rx_itr_setting with == and not &, since it is not a mask. Added
QSFP PHY support in ixgbe to allow for more accurate reporting of port
settings. Fixed the max RSS limit for X550 which is 63, not 64.
Veola fixes ixgbe ethtool reporting of backplane type interfaces as
1000/10000baseT link modes, instead, report the media as KR, KX or KX4
based on the backplane interface present.
Mark cleans up redundancy in the setting of hw_enc_features that makes
it appear that X550 has more encapsulation features than other devices.
Also do not set NETIF_F_SG any longer since that is set by the
register_netdev() call. Also fixed the X550EM_x revision check, which
needs to check a value, not just a bit.
Alex Duyck fixes additional bugs in ixgbe_clear_vf_vlans(), one being
that the mask was using a divide instead of a modulus, which resulted
in the mask bit being incorrectly set to 0 or 1 based on the value of
the VF being tested. Alex also found that he was not consistent in
using the "word" argument as an offset or as a register offset, so
made the code consistently use word as the offset in the array.
v2: dropped patch 8 of the original series, as it was undoing a part of
the fix Alex Duyck was doing in patch 9 of the original series.
Dropped based on feedback from Emil (the author).

====================
be2net: patch set
The following patch set contains some feature additions, code re-organization
and cleanup and a few non-critical fixes. Pls consider applying this to
the net-next tree. Thanks.
v3 changes: add a default case to the switch statement in patch 5 to
satisfy the compiler (-Wswitch).
v2 changes: replaced an if/else block that checks for error values with a
switch/case statement in patch 5.
Patch 1 fixes VF link state transition from disabled to auto that did
not work due to an issue in the FW. This issue could not be fixed in FW due
to some backward compatibility issues it causes with released drivers.
The issue has been fixed by introducing a new version (v2) of the cmd
from 10.6 FW onwards. This patch adds support for v2 version of this cmd.
Patch 2 reports a EOPNOTSUPP status to ethtool when the user tries to
configure BE3/SRIOV in VEPA mode as it is not supported by the chip.
Patch 3 cleansup FW flash image related constant definitions. Many of these
definitions (such as section offset values) were defined in decimal format
rather than hexa-decimal. This makes this part of the code un-readable.
Also some defines related to BE2 are labeld "g2" and defines related to BE3
are labeled "g3". This patch cleans up all of this to make this code more
readable.
Patch 4 moves the FW cmd code to be_cmds.c. All code relating to FW cmds
has been in be_cmds.[ch], excepting FW flash cmd related code.
This patch moves these routines from be_main.c to be_cmds.c.
Patch 5 adds a log message to report digital signature errors while
flashing a FW image. From FW version 11.0 onwards, the FW supports a new
"secure mode" feature (based on a jumper setting on the adapter.) In this
mode, the FW image when flashed is authenticated with a digital signature.
Patch 6 removes a line of code that has no effect.
Patch 7 removes some unused variables.
Patch 8 fixes port resource descriptor query via the GET_PROFILE FW cmd.
An earlier commit passed a specific pf_num while issuing this cmd as FW
returns descriptors for all functions when pf_num is zero. But, when pf_num
is set to a non-zero value, FW does not return the port resource descriptor.
This patch fixes this by setting pf_num to 0 while issuing the query cmd
and adds code to pick the correct NIC resource descriptor from the list of
descriptors returned by FW.
Patch 9 adds support for ethtool get-dump feature. In the past when this
option was not yet available, this feature was supported via the
--register-dump option as a workaround. This patch removes support for
FW-dump via --register-dump option as it is now available via --get-dump
option. Even though the "ethtool --register-dump" cmd which used to work
earlier, will now fail with ENOTSUPP error, we feel it is not an issue as
this is used only for diagnostics purpose.

ixgbe: Fix bugs in ixgbe_clear_vf_vlans()
When I had rewritten the code for ixgbe_clear_vf_vlans() it looks like I
had transitioned back and forth between using word as an offset and using
word as a register offset. As a result I honestly don't see how the code
was working before other than the fact that resetting the VLANs on the VF
like didn't do much to clear them.
Another issue found is that the mask was using a divide instead of a
modulus. As a result the mask bit was incorrectly being set to either bit
0 or 1 based on the value of the VF being tested. As a result the wrong
VFs were having their VLANs cleared if they were enabled.
I have updated the code so that word represents the offset in the array.
This way we can use the modulus and xor operations and they will make sense
instead of being performed on a 4 byte aligned value.
I replaced the statement "(word % 2) ^ 1" with "~word % 2" in order to
reduce the line length as the line exceeded 80 characters with the register
name inserted. The two should be equivalent so the change should be safe.

mm/vmstat: fix overflow in mod_zone_page_state()
mod_zone_page_state() takes a "delta" integer argument. delta contains
the number of pages that should be added or subtracted from a struct
zone's vm_stat field.
If a zone is larger than 8TB this will cause overflows. E.g. for a
zone with a size slightly larger than 8TB the line
in mm/page_alloc.c:free_area_init_core() will result in a negative
result for the NR_ALLOC_BATCH entry within the zone's vm_stat, since 8TB
contain 0x8xxxxxxx pages which will be sign extended to a negative
value.
Fix this by changing the delta argument to long type.
This could fix an early boot problem seen on s390, where we have a 9TB
system with only one node. ZONE_DMA contains 2GB and ZONE_NORMAL the
rest. The system is trying to allocate a GFP_DMA page but ZONE_DMA is
completely empty, so it tries to reclaim pages in an endless loop.
This was seen on a heavily patched 3.10 kernel. One possible
explaination seem to be the overflows caused by mod_zone_page_state().
Unfortunately I did not have the chance to verify that this patch
actually fixes the problem, since I don't have access to the system
right now. However the overflow problem does exist anyway.
Given the description that a system with slightly less than 8TB does
work, this seems to be a candidate for the observed problem.

mm: memcontrol: fix possible memcg leak due to interrupted reclaim
Memory cgroup reclaim can be interrupted with mem_cgroup_iter_break()
once enough pages have been reclaimed, in which case, in contrast to a
full round-trip over a cgroup sub-tree, the current position stored in
mem_cgroup_reclaim_iter of the target cgroup does not get invalidated
and so is left holding the reference to the last scanned cgroup. If the
target cgroup does not get scanned again (we might have just reclaimed
the last page or all processes might exit and free their memory
voluntary), we will leak it, because there is nobody to put the
reference held by the iterator.
The problem is easy to reproduce by running the following command
sequence in a loop:
mkdir /sys/fs/cgroup/memory/test
echo 100M > /sys/fs/cgroup/memory/test/memory.limit_in_bytes
echo $$ > /sys/fs/cgroup/memory/test/cgroup.procs
memhog 150M
echo $$ > /sys/fs/cgroup/memory/cgroup.procs
rmdir test
The cgroups generated by it will never get freed.
This patch fixes this issue by making mem_cgroup_iter avoid taking
reference to the current position. In order not to hit use-after-free
bug while running reclaim in parallel with cgroup deletion, we make use
of ->css_released cgroup callback to clear references to the dying
cgroup in all reclaim iterators that might refer to it. This callback
is called right before scheduling rcu work which will free css, so if we
access iter->position from rcu read section, we might be sure it won't
go away under us.

Driver for IBM System i/p VNIC protocol
This is a new device driver for a high performance SR-IOV assisted virtual
network for IBM System p and IBM System i systems. The SR-IOV VF will be
attached to the VIOS partition and mapped to the Linux client via the
hypervisor's VNIC protocol that this driver implements.
This driver is able to perform basic tx and rx, new features
and improvements will be added as they are being developed and tested.
