This patch makes /proc/net per network namespace. It modifies the global
variables proc_net and proc_net_stat to be per network namespace.
The proc_net file helpers are modified to take a network namespace argument,
and all of their callers are fixed to pass &init_net for that argument.
This ensures that all of the /proc/net files are only visible and
usable in the initial network namespace until the code behind them
has been updated to be handle multiple network namespaces.Making /proc/net per namespace is necessary as at least some files
in /proc/net depend upon the set of network devices which is per
network namespace, and even more files in /proc/net have contents
that are relevant to a single network namespace.Signed-off-by: Eric W. Biederman

Hopefully captured all single statement cases under net/. I'm
not too sure if there is some policy about #includes that are
"guaranteed" (ie., in the current tree) to be available through
some other #included header, so I just added linux/kernel.h to
each changed file that didn't #include it previously.Signed-off-by: Ilpo Järvinen

Reported by Chris Evans :

Commit 4cf92a3c was submitted as a fix for bug #8686 at bugzilla.kernel.org
(http://bugzilla.kernel.org/show_bug.cgi?id=8686). Unfortunately, the fix led to
a new bug, reported by Yoshifuji Hideaki, that prevented association for WEP
encrypted networks that use ifconfig to control the device. This patch effectively
reverts the earlier commit and does a proper fix for bug #8686.Signed-off-by: Larry Finger

Signed-off-by: David S. Miller -
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.Signed-off-by: Arnaldo Carvalho de Melo

For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can
later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in

"complex" cases.Signed-off-by: Arnaldo Carvalho de Melo

There is a bug in ieee80211softmac that always sets the user rate
to 11Mbs, no matter the capabilities of the device. This bug was
probably beneficial as long as the bcm43xx cards were rate limited;
however, most are now capable of relatively high speeds. This patch
fixes that bug and eliminates an assert that is no longer needed.Once the cards are capable of full OFDM speeds, the 24 Mbs rate will
be changed to 54 Mbs.Signed-off-by: Larry Finger

The signature of work functions changed recently from a context
pointer to the work structure pointer. This caused a problem in
the ieee80211softmac code, because the ieee80211softmac_assox_work
function has been called directly with a parameter explicitly
casted to (void*). This compiled correctly but resulted in a
softlock, because mutex_lock was called with the wrong memory
address. The patch fixes the problem. Another issue was a wrong
call of the schedule_work function. Softmac works again and this
fixes the problem I mentioned earlier in the zd1211rw rx tasklet
patch. The patch is against Linus' tree (commit af1713e0).Signed-off-by: Ulrich Kunitz
