Dumps the statistic common to all action modules via the newly
introduced TLV type TCA_ACT_STATS in tcf_action_copy_stats but
allows the corresponding module to dump its own statistic by
implementing the get_stats callback.

Introduces a fixed size variant of ifmap for rtnetlink. Fixes
issues with address size mismatch between kernel and userspace.
Obviously this will fail if userspace provides an address greater
than 32bit.

This also solved a problem noticed by Thomas Graf
in that RTATTR_MAX had become incorrect recently
due to IFLA_MAX increasing and thus becomming the
largest one.

Rtnetlink has some macro's that are relics from earlier locking.
They are only used a couple of places so are easy to kill.

This patch implements both per interface and global new IPv6 MIBs counters
through netlink based on new IP MIBs draft, 64 bit counters are not supported
here because of performance issues. It coexists old IPv6 MIBs counters (which
are through proc file system) for the compatibility.

Change ASSERT_RTNL and BUG_TRAP
- unlikely to occur
- tag message as error
- dump_stack in ASSERT_RTNL to aide finding code path
- make all format's which a smart compiler can optimize

1) Remove srtt etc. tests in tcp_init_cwnd, was buggy
anyways.
2) Add RTAX_INITCWMD route metric, use this in tcp_init_cwnd()
if non-zero.
3) Add RTAX_FEATURES (to enable/disable ECN/SACK/TIMESTAMPS
on a per-route basis), currently unused.

With this the data dependency is reduced to just making sure that the first
member of both struct sock and struct tcp_tw_bucket are a struct sock_common.
Also makes it easier to grep for struct sock and struct tcp_tw_bucket usage in
the tree as all the members in those structs are prefixed, respectively, with
sk_ and tw_, like struct inode (i_), struct block_device (bd_), etc.
Checked namespace with make tags/ctags, just one colision with the macros for
the struct sock members, with a wanrouter struct, fixed that
s/sk_state/state_sk/g in the wanrouter struct.
Checked as well if the names of the members in both structs collided with some
macro, none found.

Revert the rtnl_lock API change, it is totally unneeded.
Instead we manage the todo work inside of net/core/dev.c
Also, we have to move sbin hotplug invocation outside of
the RTNL semaphore as well, both for register and unregister.
|
|
We had two major issues when unregistering networking devices.
1) Even trying to run hotplug asynchronously could deadlock
if keventd was currently trying to get the RTNL semaphore
in order to process linkwatch events.
2) Unregister needs to wait for the last reference to go away
before the finalization of the unregister can execute. This
cannot occur under the RTNL semaphore as this is deadlock
prone as well.
The solution is to do all of this stuff after dropping the
RTNL semaphore. rtnl_lock, if it is about to protect a region
of code that could unregister network devices, registers a list
to which unregistered netdevs are attached. At rtnl_unlock time
this list is processed to wait for refcounts to drop to zero and
then finalize the unregister.

- Add ARPHRD_INFINIBAND
- Increase MAX_ADDR_LEN to 32 from 8
- Add suitable length protection to SIOCGIFHWADDR and friends.
- Add RTM_SETLINK for portably setting larger hw addrs.

Quick summary : this patch build on the first part to offer
two important new features :
o Wireless Events
o Wireless Cell Scanning
Wireless Events are events generated by device, driver or the
wireless subsystem. It allows for example a device to notify user
space when it register to a new cell (roaming) or loose contact with
the current Access Points. Currently, the other defined events include
some configuration changes and packet drop due to excessive retries,
more may come in the future. All those events are useful for MobileIP,
V-Handoff and Ad-Hoc routing.
Wireless Cell Scanning is a generic API to allow device/drive
to report Wireless Cells discovered (including ESSID, frequency and
QoS). This is similar to what is available in WindowsXP (except that
it's compliant to Wireless Extensions).
This patch has been submitted for review on this list a couple
of time in January, has been on my web page since and used intensively
by other people. It was rediffed to 2.5.6. Driver patches have been
submitted to maintainers.
