This patch doesn't change how the code works because in the current
kernel gfp is always GFP_KERNEL. But gfp was obviously intended
instead of GFP_KERNEL.

I had a report recently of a user trying to use dropwatch to localise some frame
loss, and they were getting false positives. Turned out they were using a user
space SCTP stack that used raw sockets to grab frames. When we don't have a
registered protocol for a given packet, we record it as a drop, even if a raw
socket receieves the frame. We should only record the drop in the event a raw
socket doesnt exist to receive the frames
Tested by the reported successfully

John W. Linville says:
====================
This is another flurry of fixes intended for the 3.9 stream...
A mac80211 pull from Johannes:
"Seth fixes a stupid bug I introduced into one of his earlier patches,
Chun-Yeow fixes mesh forwarding and Felix fixes monitor mode. I myself
fixed a small locking issue and, the biggest change here, removed some
nl80211 information with which sometimes the per wiphy information was
getting too large for the typical 4k-minus-overhead. In my -next tree I
have a patch to allow splitting that and add back the information
removed now."
An iwlwifi pull from Johannes:
"I have a fix for a pretty important bug regarding DMA mapping, that
could cause the DMA engine to overwrite data we wanted to send to it, so
that the next time we send it it would be bad. This particularly affects
calibration results. Other than that, three little fixes for the MVM
driver."
But wait, there's more!
Avinash Patil fixes an incorrectly timed delay in mwifiex.
Bing Zhao prevents a crash in SD8688 caused by failing to properly
set a flag before issuing a command.
Felix Fietkau is the big here this time, providing a trio of minor
ath9k fixes and correcting the advertised interface combinations for
rt2x00 when mesh support is disabled.
Finally, Hauke Mehrtens gives us a patch that correctlin initializes
a spin lock in the bcma code.
Please let me know if there are problems!

The sendmsg() syscall handler for PPPoL2TP doesn't decrease the socket
reference counter after successful transmissions. Any successful
sendmsg() call from userspace will then increase the reference counter
forever, thus preventing the kernel's session and tunnel data from
being freed later on.
The problem only happens when writing directly on L2TP sockets.
PPP sockets attached to L2TP are unaffected as the PPP subsystem
uses pppol2tp_xmit() which symmetrically increase/decrease reference
counters.
This patch adds the missing call to sock_put() before returning from
pppol2tp_sendmsg().

Given a device with many channels capabilities the wiphy
information can still overflow even though its size in
3.9 was reduced to 3.8 levels. For new userspace and
kernel 3.10 we're going to implement a new "split dump"
protocol that can use multiple messages per wiphy.
For now though, add a workaround to be able to send more
information to userspace. Since generic netlink doesn't
have a way to set the minimum dump size globally, and we
wouldn't really want to set it globally anyway, increase
the size only when needed, as described in the comments.
As userspace might not be prepared for large buffers, we
can only use 4k.
Also increase the size for the get_wiphy command.

Pull nfsd changes from J Bruce Fields:
"Miscellaneous bugfixes, plus:
- An overhaul of the DRC cache by Jeff Layton. The main effect is
just to make it larger. This decreases the chances of intermittent
errors especially in the UDP case. But we'll need to watch for any
reports of performance regressions.
- Containerized nfsd: with some limitations, we now support
per-container nfs-service, thanks to extensive work from Stanislav
Kinsbursky over the last year."
Some notes about conflicts, since there were *two* non-data semantic
conflicts here:
- idr_remove_all() had been added by a memory leak fix, but has since
become deprecated since idr_destroy() does it for us now.
- xs_local_connect() had been added by this branch to make AF_LOCAL
connections be synchronous, but in the meantime Trond had changed the
calling convention in order to avoid a RCU dereference.
There were a couple of more obvious actual source-level conflicts due to
the hlist traversal changes and one just due to code changes next to
each other, but those were trivial.

"A few groups of patches here. Alex has been hard at work improving

There are a few changes to the data layout. Jim Schutt's patch fixes

improved hashing strategy across storage nodes (when the server side
supports it too).
A pair of patches from Sam Lang fix the atomicity of open+create
operations. Several patches from Yan, Zheng fix various mds/client
issues that turned up during multi-mds torture tests.
A final set of patches expose file layouts via virtual xattrs, and
allow the policies to be set on directories via xattrs as well
(avoiding the awkward ioctl interface and providing a consistent

In sctp_ulpq_tail_data(), use return values 0,1 to indicate whether
a complete event (with MSG_EOR set) was delivered. A return value
of -ENOMEM continues to indicate an out-of-memory condition was
encountered.
In sctp_ulpq_retrieve_partial() and sctp_ulpq_retrieve_first(),
correct message reassembly logic for SCTP partial delivery.
Change logic to ensure that as much data as possible is sent
with the initial partial delivery and that following partial
deliveries contain all available data.
In sctp_ulpq_partial_delivery(), attempt partial delivery only
if the data on the head of the reassembly queue is at or before
the cumulative TSN ACK point.
In sctp_ulpq_renege(), use the modified return values from
sctp_ulpq_tail_data() to choose whether to attempt partial
delivery or to attempt to drain the reassembly queue as a
means to reduce memory pressure. Remove call to
sctp_tsnmap_mark(), as this is handled correctly in call to
sctp_ulpq_tail_data().

Also, using a workqueue for the connect means we lose the namespace

I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator
properly, so those had to be fixed up manually.

The legacy behavior adds the pgid seed and pool together as the input for
CRUSH. That is problematic because each pool's PGs end up mapping to the
same OSDs: 1.5 == 2.4 == 3.3 == ...
Instead, if the HASHPSPOOL flag is set, we has the ps and pool together and
feed that into CRUSH. This ensures that two adjacent pools will map to
an independent pseudorandom set of OSDs.
Advertise our support for this via a protocol feature flag.

Some mlme work structs are not cancelled on disassociation
nor interface deletion, which leads to them running after
the memory has been freed
There is not a clean way to cancel these in the disassociation
logic because they must be canceled outside of the ifmgd->mtx
lock, so just cancel them in mgd_stop logic that tears down
the station.

When the driver does not want a monitor mode VIF, no channel context is
allocated for it. This causes ieee80211_recalc_idle to put the hardware
into idle mode if only a monitor mode is active, breaking injection.
Fix this by checking local->monitors in addition to active channel
contexts.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace and namespace infrastructure changes from Eric W Biederman:
"This set of changes starts with a few small enhnacements to the user
namespace. reboot support, allowing more arbitrary mappings, and
support for mounting devpts, ramfs, tmpfs, and mqueuefs as just the
user namespace root.
I do my best to document that if you care about limiting your
unprivileged users that when you have the user namespace support
enabled you will need to enable memory control groups.
There is a minor bug fix to prevent overflowing the stack if someone
creates way too many user namespaces.
The bulk of the changes are a continuation of the kuid/kgid push down
work through the filesystems. These changes make using uids and gids
typesafe which ensures that these filesystems are safe to use when
multiple user namespaces are in use. The filesystems converted for
3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The
changes for these filesystems were a little more involved so I split
the changes into smaller hopefully obviously correct changes.
XFS is the only filesystem that remains. I was hoping I could get
that in this release so that user namespace support would be enabled
with an allyesconfig or an allmodconfig but it looks like the xfs
changes need another couple of days before it they are ready."

Just like the radar information, the TCP WoWLAN capability
data can increase the wiphy information and make it too
big. Remove the TCP WoWLAN information; no driver supports
it and new userspace tools will be required as well.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>

The wiphy information is getting very close to being too
much for a typical netlink dump message and adding the
radar attributes to channels and interface combinations
can push it over the limit, which means userspace gets no
information whatsoever. Therefore, remove these again for
now, no driver actually supports radar detection anyway
and a modified userspace is required as well.
We're working on a solution that will allow userspace to
request splitting the information across multiple netlink
messages, which will allow us to add this back.

This just converts a manually-implemented loop into a do..while loop
in con_work(). It also moves handling of EAGAIN inside the blocks
where it's already been determined an error code was returned.
Also update a few dout() calls near the affected code for

This just rearranges the logic in con_work() a little bit so that a
flag is used to indicate a fault has occurred. This allows both the
fault and non-fault case to be handled the same way and avoids a

An error occurring on a ceph connection is treated as a fault,
causing the connection to be reset. The initial part of this fault
handling has to be done while holding the connection mutex, but
it must then be dropped for the last part.
Separate the part of this fault handling that executes without the
lock into its own function, con_fault_finish(). Move the call to
this new function, as well as call that drops the connection mutex,
into ceph_fault(). Rename that function con_fault() to reflect that
it's only handling the connection part of the fault handling.
The motivation for this was a warning from sparse about the locking
being done here. Rearranging things this way keeps all the mutex
manipulation within ceph_fault(), and this stops sparse from
complaining.
This partially resolves:

Collect the code that tests for and implements a backoff delay for a
ceph connection into a new function, ceph_backoff().
Make the debug output messages in that part of the code report
things consistently by reporting a message in the socket closed
case, and by making the one for PREOPEN state report the connection
pointer like the rest.
