The wireless extensions have a copy_from_user to a local stack
array "essid", but both me and gcc have failed to find where
the bounds for this copy are located in the code.
This patch adds some basic sanity checks for the copy length
to make sure that we don't overflow the stack buffer.

Multiple problems were reported due to interaction
between wpa_supplicant and the wext compat code in
cfg80211, which appear to be due to it not getting
any bss pointer here when wpa_supplicant sets all
parameters -- do that now. We should still get the
bss after doing an extra scan, but that appears to
increase the time we need for connecting enough to
sometimes cause timeouts.

Currently, cfg80211's SIOCGIWAP implementation returns
the BSSID that the user set, even if the connection has
since been dropped due to other changes. It only should
return the current BSSID when actually connected.

The sys_socketcall() function has a very clever system for the copy
size of its arguments. Unfortunately, gcc cannot deal with this in
terms of proving that the copy_from_user() is then always in bounds.
This is the last (well 9th of this series, but last in the kernel) such
case around.
With this patch, we can turn on code to make having the boundary provably
right for the whole kernel, and detect introduction of new security
accidents of this type early on.

There is a potential double-kfree in net/bridge/br_if.c. If br_fdb_insert
fails, then the kobject is put back (which calls kfree due to the kobject
release), and then kfree is called again on the net_bridge_port. This
patch fixes the crash.

This reverts commit 645069299a1c7358cf7330afe293f07552f11a5d.
While the code does not actually break anything, it does not completely follow
RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the
ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better
implemented in userspace.
The kernel should not send RS packages for ISATAP at all.

netlink_unicast() calls kfree_skb even in the error case.
dcbnl calls netlink_unicast() which when it fails free's the

Similar to commit d136f1bd366fdb7e747ca7e0218171e7a00a98a5,

It seems recursion field from "struct ip_tunnel" is not anymore needed.
recursion prevention is done at the upper level (in dev_queue_xmit()),
since we use HARD_TX_LOCK protection for tunnels.
This avoids a cache line ping pong on "struct ip_tunnel" : This structure
should be now mostly read on xmit and receive paths.

- only delay if packet was successfully sent
- if delay is 100ns and it takes 10ns to build packet then

Due to man page of setsockopt, if optlen is not valid, kernel should return
-EINVAL. But a simple testcase as following, errno is 0, which means setsockopt
is successful.
addr.s_addr = inet_addr("192.1.2.3");
setsockopt(s, IPPROTO_IP, IP_MULTICAST_IF, &addr, 1);
printf("errno is %d\n", errno);
Xiaotian Feng(dfeng@redhat.com) caught the bug. We fix it firstly checking
the availability of optlen and then dealing with the logic like other options.

[[resending with correct cc: - "vfs.kernel.org" just isn't right!]]
xprt->reestablish_timeout is used to cause TCP connection attempts to
back off if the connection fails so as not to hammer the network,
but to still allow immediate connections when there is no reason to
believe there is a problem.
It is not used for the first connection (when transport->sock is NULL)
but only on reconnects.
It is currently set:
a/ to 0 when xs_tcp_state_change finds a state of TCP_FIN_WAIT1
on the assumption that the client has closed the connection
so the reconnect should be immediate when needed.
b/ to at least XS_TCP_INIT_REEST_TO when xs_tcp_state_change
detects TCP_CLOSING or TCP_CLOSE_WAIT on the assumption that the
server closed the connection so a small delay at least is
required.
c/ as above when xs_tcp_state_change detects TCP_SYN_SENT, so that
it is never 0 while a connection has been attempted, else
the doubling will produce 0 and there will be no backoff.
d/ to double is value (up to a limit) when delaying a connection,
thus providing exponential backoff and
e/ to XS_TCP_INIT_REEST_TO in xs_setup_tcp as simple initialisation.
So you can see it is highly dependant on xs_tcp_state_change being
called as expected. However experimental evidence shows that
xs_tcp_state_change does not see all state changes.
("rpcdebug -m rpc trans" can help show what actually happens).
Results show:
TCP_ESTABLISHED is reported when a connection is made. TCP_SYN_SENT
is never reported, so rule 'c' above is never effective.
When the server closes the connection, TCP_CLOSE_WAIT and
TCP_LAST_ACK *might* be reported, and TCP_CLOSE is always
reported. This rule 'b' above will sometimes be effective, but
not reliably.
When the client closes the connection, it used to result in
TCP_FIN_WAIT1, TCP_FIN_WAIT2, TCP_CLOSE. However since commit
f75e674 (SUNRPC: Fix the problem of EADDRNOTAVAIL syslog floods on
reconnect) we don't see *any* events on client-close. I think this
is because xs_restore_old_callbacks is called to disconnect
xs_tcp_state_change before the socket is closed.
In any case, rule 'a' no longer applies.
So all that is left are rule d, which successfully doubles the
timeout which is never rest, and rule e which initialises the timeout.
Even if the rules worked as expected, there would be a problem because
a successful connection does not reset the timeout, so a sequence
of events where the server closes the connection (e.g. during failover
testing) will cause longer and longer timeouts with no good reason.
This patch:
- sets reestablish_timeout to 0 in xs_close thus effecting rule 'a'
- sets it to 0 in xs_tcp_data_ready to ensure that a successful
connection resets the timeout
- sets it to at least XS_TCP_INIT_REEST_TO after it is doubled,
thus effecting rule c
I have not reimplemented rule b and the new version of rule c
seems sufficient.
I suspect other code in xs_tcp_data_ready needs to be revised as well.
For example I don't think connect_cookie is being incremented as often
as it should be.

When cfg80211 is instructed to connect, it always
uses the default WEP key for the privacy setting,
which clearly is wrong when using wpa_supplicant.
Don't overwrite the setting, and rely on it being

set it to true when we have keys.

When the DTIM setting is read from beacons, mac80211 will
assume it is 1 if the TIM IE is not present or the value
is 0. This sounds fine, but the same function processes
probe responses as well, which don't have a TIM IE. This
leads to overwriting any values previously parsed out of
beacon frames.
Thus, instead of checking for the presence of the TIM IE
when setting the default, simply check whether the DTIM
period value is valid already. If the TIM IE is not there
then the value cannot be valid (it is initialised to 0)
and probe responses received after beacons will not lead
to overwriting an already valid value.

There's a check saying
/* we're good if we have both BSSID and channel */
if (wdev->conn->params.bssid && wdev->conn->params.channel) {
but that isn't true -- we need the BSS struct. This leads
to errors such as
Trying to associate with 00:1b:53:11:dc:40 (SSID='TEST' freq=2412 MHz)
ioctl[SIOCSIWFREQ]: No such file or directory
ioctl[SIOCSIWESSID]: No such file or directory
Association request to the driver failed
Associated with 00:1b:53:11:dc:40
in wpa_supplicant, as reported by Holger.
Instead, we really need to have the BSS struct, and if we
don't, then we need to initiate a scan for it. But we may
already have the BSS struct here, so hang on to it if we
do and scan if we don't.

Sizing of memory allocations shouldn't depend on the number of physical
pages found in a system, as that generally includes (perhaps a huge amount
of) non-RAM pages. The amount of what actually is usable as storage
should instead be used as a basis here.
Some of the calculations (i.e. those not intending to use high memory)
should likely even use (totalram_pages - totalhigh_pages).

In cache_defer_req, 'dreq' is used for two significantly different
values that happen to be of the same type.
This is both confusing, and makes it hard to extend the range of one of
the values as we will in the next patch.
So introduce 'discard' to take one of the values.

Using list_del_init is generally safer than list_del, and it will
allow us, in a subsequent patch, to see if an entry has already been
processed or not.
