The MSSR constants didn't match the reality - bitfield declarations used
to be correct (1000BT_FD - bit 11, 1000BT_HD - bit 10), but enum had
them the other way round. Went unnoticed until the switch from the
bitfields use to the explicit arithmetics and I hadn't caught that one
when verifying correctness of change...

Since it's acquired from irq context, all locking must be of the
irq safe variant. Most are already inside the queue lock (which
already disables interrupts), but the io scheduler rmmod path
always has irqs enabled and the put_io_context() path may legally
be called with irqs enabled (even if it isn't usually). So fixup
those two.

Andre Majorel <aym-xunil@teaser.fr> points out that if we only updated
the atime when we transfer some data, we deviate from the standard
of always updating the atime. So change splice to always call
file_accessed() even if splice_direct_to_actor() didn't transfer
any data.

A few places missed the "a" specifier for the __ex_table section. Add
these so we avoid generation an additional section at link time.
Latest modpost would otherwise complain like this:
WARNING: vmlinux.o (__ex_table.2): section name inconsistency.

Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains

The namespace is not available in the fib_sync_down_addr, add it as a
parameter.
Looking up a device by the pointer to it is OK. Looking up using a
result from fib_trie/fib_hash table lookup is also safe. No need to
fix that at all. So, just fix lookup by address and insertion to the
hash table path.

Add new "flow" classifier, which is meant to extend the SFQ hashing
capabilities without hard-coding new hash functions and also allows
deterministic mappings of keys to classes, replacing some out of tree
iptables patches like IPCLASSIFY (maps IPs to classes), IPMARK (maps
IPs to marks, with fw filters to classes), ...
Some examples:
- Classic SFQ hash:
tc filter add ... flow hash \
keys src,dst,proto,proto-src,proto-dst divisor 1024
- Classic SFQ hash, but using information from conntrack to work properly in
combination with NAT:
tc filter add ... flow hash \
keys nfct-src,nfct-dst,proto,nfct-proto-src,nfct-proto-dst divisor 1024
- Map destination IPs of 192.168.0.0/24 to classids 1-257:
tc filter add ... flow map \
key dst addend -192.168.0.0 divisor 256
- alternatively:
tc filter add ... flow map \
key dst and 0xff
- similar, but reverse ordered:
tc filter add ... flow map \
key dst and 0xff xor 0xff
Perturbation is currently not supported because we can't reliable kill the
timer on destruction.

checking for both the 1000Base-X bit and the 10/100/1000Base-T bit.

Current ip route cache implementation is not suited to large caches.
We can consume a lot of CPU when cache must be invalidated, since we
currently need to evict all cache entries, and this eviction is
sometimes asynchronous. min_delay & max_delay can somewhat control this
asynchronism behavior, but whole thing is a kludge, regularly triggering
infamous soft lockup messages. When entries are still in use, this also
consumes a lot of ram, filling dst_garbage.list.
A better scheme is to use a generation identifier on each entry,
so that cache invalidation can be performed by changing the table
identifier, without having to scan all entries.
No more delayed flushing, no more stalling when secret_interval expires.
Invalidated entries will then be freed at GC time (controled by
ip_rt_gc_timeout or stress), or when an invalidated entry is found
in a chain when an insert is done.
Thus we keep a normal equilibrium.
This patch :
- renames rt_hash_rnd to rt_genid (and makes it an atomic_t)
- Adds a new rt_genid field to 'struct rtable' (filling a hole on 64bit)
- Checks entry->rt_genid at appropriate places :

Since the old policer code is gone, TC actions are needed for policing.
The ingress qdisc can get packets directly from netif_receive_skb()
in case TC actions are enabled or through netfilter otherwise, but
since without TC actions there is no policer the only thing it actually
does is count packets.
Remove the netfilter support and always require TC actions.

rtnl_link_register() fails.
In drivers/net/macvlan.c, when rtnl_link_register() fails in
macvlan_init_module(), there is no point to set it (second time in

return a negative number, so instead this patch sets

Reuse the existing logic for multicast list synchronization for the
unicast address list. The core of dev_mc_sync/unsync are split out as
__dev_addr_sync/unsync and moved from dev_mcast.c to dev.c. These are
then used to implement dev_unicast_sync/unsync as well.
I'm working on cleaning up Intel's FCoE stack, which generates new MAC
addresses from the fibre channel device id assigned by the fabric as
per the current draft specification in T11. When using such a
protocol in a VLAN environment it would be nice to not always be
forced into promiscuous mode, assuming the underlying Ethernet driver
supports multiple unicast addresses as well.

Normally during a dump the key of the last dumped entry is used for
continuation, but since lock is dropped it might be lost. In that case
fallback to the old counter based N^2 behaviour. This means the dump
will end up skipping some routes which matches what FIB_HASH does.

- Remove an unused definition (LAT_BUCKETS_MAX) in net/core/pktgen.c.
- Remove the corresponding comment.
- The LAT_BUCKETS_MAX seems to have to do with a patch from a long

counters.

This is needed because in ndisc.c, we have:
static void ndisc_router_discovery(struct sk_buff *skb)
{
// ...
if (ndopts.nd_opts_mtu) {
// ...
if (rt)
rt->u.dst.metrics[RTAX_MTU-1] = mtu;
rt6_mtu_change(skb->dev, mtu);
// ...
}
Since the mtu is set directly here, rt6_mtu_change_route thinks that
it is unchanged, and so it fails to update the MSS accordingly. This
patch lets rt6_mtu_change_route still update MSS if old_mtu == new_mtu.
