The assertion that checks for sge context overflow is
incorrectly hard-coded to 32. This causes a kernel bug
check when using big-data mounts. Changed the BUG_ON to
use the computed value RPCSVC_MAXPAGES.

RDMA connection shutdown on an SMP machine can cause a kernel crash due
to the transport close path racing with the I/O tasklet.
Additional transport references were added as follows:
- A reference when on the DTO Q to avoid having the transport
deleted while queued for I/O.
- A reference while there is a QP able to generate events.
- A reference until the DISCONNECTED event is received on the CM ID

Since the lists are circular, we need to explicitely tag
the address to be deleted since we might end up freeing
the list head instead. This fixes some interesting SCTP
crashes.

With TSO it was possible to send past the receiver window when the skb
to be sent was the last in the write queue while the receiver window
is the limiting factor. One can notice that there's a loophole in the
tcp_mss_split_point that lacked a receiver window check for the
tcp_write_queue_tail() if also cwnd was smaller than the full skb.
Noticed by Thomas Gleixner <tglx@linutronix.de> in form of "Treason
uncloaked! Peer ... shrinks window .... Repaired." messages (the peer
didn't actually shrink its window as the message suggests, we had just
sent something past it without a permission to do so).

handler
Commit ce7663d84:
[NETFILTER]: nfnetlink_queue: don't unregister handler of other subsystem
changed nf_unregister_queue_handler to return an error when attempting to
unregister a queue handler that is not identical to the one passed in.
This is correct in case we really do have a different queue handler already
registered, but some existing userspace code always does an unbind before
bind and aborts if that fails, so try to be nice and return success in
that case.

0 exists
Similar to the nfnetlink_log problem, nfnetlink_queue incorrectly
returns -EPERM when binding or unbinding to an address family and
queueing instance 0 exists and is owned by a different process. Unlike
nfnetlink_log it previously completes the operation, but it is still
incorrect.

exists
When binding or unbinding to an address family, the res_id is usually set
to zero. When logging instance 0 already exists and is owned by a different
process, this makes nfunl_recv_config return -EPERM without performing
the bind operation.
Since no operation on the foreign logging instance itself was requested,
this is incorrect. Move bind/unbind commands before the queue instance
permissions checks.
Also remove an incorrect comment.

From: Andrew Schulman <andrex@alumni.utexas.net>
xt_time_match() in net/netfilter/xt_time.c in kernel 2.6.24 never
matches on Sundays. On my host I have a rule like
iptables -A OUTPUT -m time --weekdays Sun -j REJECT
and it never matches. The problem is in localtime_2(), which uses
r->weekday = (4 + r->dse) % 7;
to map the epoch day onto a weekday in {0,...,6}. In particular this
gives 0 for Sundays. But 0 has to be wrong; a weekday of 0 can never
match. xt_time_match() has
if (!(info->weekdays_match & (1 << current_time.weekday)))
return false;
and when current_time.weekday = 0, the result of the & is always
zero, even when info->weekdays_match = XT_TIME_ALL_WEEKDAYS = 0xFE.

This patch is similar to nfnetlink_queue fixes. It fixes the computation
of skb size by using NLMSG_SPACE instead of NLMSG_ALIGN.

Size of the netlink skb was wrongly computed because the formula was using
NLMSG_ALIGN instead of NLMSG_SPACE. NLMSG_ALIGN does not add the room for
netlink header as NLMSG_SPACE does. This was causing a failure of message
building in some cases.
On my test system, all messages for packets in range [8*k+41, 8*k+48] where k
is an integer were invalid and the corresponding packets were dropped.

If an address family is not listed in "Supported Address Types"
parameter(INIT Chunk), but the packet is sent by that family, this
address family should be considered as supported by peer. Otherwise,
an error condition will occur. For instance, if kernel receives an
IPV6 SCTP INIT chunk with "Support Address Types" parameter which
indicates just supporting IPV4 Address family. Kernel will reply an
IPV6 SCTP INIT ACK packet, but the source ipv6 address in ipv6 header
will be vacant. This is not correct.
refer to RFC4460 as following:
IMPLEMENTATION NOTE: If an SCTP endpoint lists in the 'Supported
Address Types' parameter either IPv4 or IPv6, but uses the other
family for sending the packet containing the INIT chunk, or if it
also lists addresses of the other family in the INIT chunk, then
the address family that is not listed in the 'Supported Address
Types' parameter SHOULD also be considered as supported by the
receiver of the INIT chunk. The receiver of the INIT chunk SHOULD
NOT respond with any kind of error indication.
Here is a fix to comply to RFC.

Reinette pointed out that with the sta_info RCU-ification
the behaviour here changed and the conf_tx callback is
now invoked under RCU read lock. That is not necessary so
this patch restores the original behaviour

The mac80211 MLME requires restarting timers after a scan
completes but this wasn't done when hardware scan offload
was added, so add it now.

they were the reason why Johannes marked mesh as BROKEN, that flag has been

Today I hit one of my new WARN_ONs in the mac80211 code because
a key wasn't being freed correctly. After wondering for a while
I finally tracked it to the fact that STA keys aren't added to
the per-sdata key list correctly, they are supposed to always be
on that list, not just for default keys. This patch fixes that.

I noticed a bug I introduced when mesh is enabled: sta_info_destroy()
will end up calling cancel_timer() on a timer that has never been
initialized because the timer is only initialized in mesh_plink_alloc(),
not in sta_info_alloc(). This patch moves the initialization of all mesh
related fields into sta_info_alloc(), adds a bit of sanity checking to
the cfg80211 handlers and sta_info_insert() and makes mesh_plink_alloc()
a static helper function that is only used from the mesh plink code.

Quite a while ago I started this book. The required kernel-doc
patches have since gone into the tree so it is now possible to
build the book in mainline.
The actual documentation is still rather incomplete and not all
things are linked into the book, but this enables us to edit
the documentation collaboratively, hopefully driver authors can
add documentation based on their experience with mac80211.

When we take down an interface, we need to remove the STA info
items that belong to it because otherwise we might invoke a
sta_notify() callback in the driver when we later delete the
STA entries, but in that case the driver will already have
removed its knowledge of the interface they belonged to leading
to confusion. Also, we could invoke the set_tim() callback after
the driver removed its knowledge of the interface, which can
lead to a crash if it requests a beacon with a then-invalid vif
pointer!
A side effect of this patch is that, because it was easier, it
disallows changing the WDS peer while an interface is up. Should
that actually be necessary, it can be added back, but the WDS
peer STA entry may not be added while the interface is UP so for
now I've simplified the WDS peer's STA entry lifetime management.
