[SKBUFF]: Keep track of writable header len of headerless clones

Currently NAT (and others) that want to modify cloned skbs copy them,
even if in the vast majority of cases its not necessary because the
skb is a clone made by TCP and the portion NAT wants to modify is
actually writable because TCP release the header reference before
cloning.

The problem is that there is no clean way for NAT to find out how
long the writable header area is, so this patch introduces skb->hdr_len
to hold this length. When a headerless skb is cloned skb->hdr_len
is set to the current headroom, for regular clones it is copied from
the original. A new function skb_clone_writable(skb, len) returns
whether the skb is writable up to len bytes from skb->data. To avoid
enlarging the skb the mac_len field is reduced to 16 bit and the
new hdr_len field is put in the remaining 16 bit.

I've done a few rough benchmarks of NAT (not with this exact patch,
but a very similar one). As expected it saves huge amounts of system
time in case of sendfile, bringing it down to basically the same
amount as without NAT, with sendmsg it only helps on loopback,
probably because of the large MTU.

Transmit a 1GB file using sendfile/sendmsg over eth0/lo with and
without NAT:

- sendfile eth0, no NAT: sys     0m0.388s
- sendfile eth0, NAT: sys     0m1.835s
- sendfile eth0: NAT + path: sys     0m0.370s (~ -80%)

- sendfile lo, no NAT: sys     0m0.258s
- sendfile lo, NAT: sys     0m2.609s
- sendfile lo, NAT + patch: sys     0m0.260s (~ -90%)

- sendmsg eth0, no NAT: sys     0m2.508s
- sendmsg eth0, NAT: sys     0m2.539s
- sendmsg eth0, NAT + patch: sys     0m2.445s (no change)

- sendmsg lo, no NAT: sys 0m2.151s
- sendmsg lo, NAT: sys     0m3.557s
- sendmsg lo, NAT + patch: sys     0m2.159s (~ -40%)

I expect other users can see a similar performance improvement,

  wrongly to do a trylock (despite LLTX being set), the driver returns
  LOCKED. But since lockless is zero, the packet is requeue'd instead of
  calling collision code which will issue warning and free up the skb.
  Instead this skb will be retried with this driver next time, and the same
  result will ensue. Removing this check will catch these driver bugs instead
  of hiding the problem. I am keeping this change to readability section
  since :
   a. it is confusing to check two things as it is; and
   b. it is difficult to keep this check in the changed 'switch' code.

- Changed some names, like try_get_tx_pkt to dev_dequeue_skb (as that is
  the work being done and easier to understand) and do_dev_requeue to
  dev_requeue_skb, merged handle_dev_cpu_collision and tx_islocked to
  dev_handle_collision (handle_dev_cpu_collision is a small routine with only
  one caller, so there is no need to have two separate routines which also
  results in getting rid of two macros, etc.

- Removed an XXX comment as it should never fail (I suspect this was related
  to batch skb WIP, Jamal ?). Converted some functions to original coding

cond_resched_softirq for each entry, we still won't process

This anomaly comes from the 2.4 code where this was all in a

as a small optimisation.

The cost of each local_bh_disable is so small when compared
against the increased latency in keeping it disabled over a

The code for such iteration is identical in all the places, so it's worth

17 years agobonding / ipv6: no addrconf for slaves separately from master
Jay Vosburgh [Mon, 9 Jul 2007 17:42:47 +0000 (10:42 -0700)]
bonding / ipv6: no addrconf for slaves separately from master

At present, when a device is enslaved to bonding, if ipv6 is
active then addrconf will be initated on the slave (because it is closed
then opened during the enslavement processing).  This causes DAD and RS
packets to be sent from the slave.  These packets in turn can confuse
switches that perform ipv6 snooping, causing them to incorrectly update
their forwarding tables (if, e.g., the slave being added is an inactve
backup that won't be used right away) and direct traffic away from the
active slave to a backup slave (where the incoming packets will be
dropped).

This patch alters the behavior so that addrconf will only run on
the master device itself.  I believe this is logically correct, as it
prevents slaves from having an IPv6 identity independent from the
master.  This is consistent with the IPv4 behavior for bonding.

This is accomplished by (a) having bonding set IFF_SLAVE sooner
in the enslavement processing than currently occurs (before open, not
after), and (b) having ipv6 addrconf ignore UP and CHANGE events on
slave devices.

The eql driver also uses the IFF_SLAVE flag.  I inspected eql,
and I believe this change is reasonable for its usage of IFF_SLAVE, but
I did not test it.

phylib: cleanup marvell.c a bit

Simplify the marvell driver init a bit: Make the supported devices an
array instead of explicitly registering each structure. This makes it
considerably easier to add new devices down the road.

Here's a slightly cleaner way of creating the /proc structure for the
pnx8850.  mostly, it creates a directory with default mode 555, since the
one you're creating is mode 444, which is somewhat unusual for a directory
