There is nothing related to BH in SNMP counters anymore,
since linux-3.0.Rename helpers to use __ prefix instead of _BH prefix,
for contexts where preemption is disabled.This more closely matches convention used to update
percpu variables.Signed-off-by: Eric Dumazet

There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.Signed-off-by: Joe Perches

Now we handle icmp errors in each transport protocol's err_handler,
for icmp protocols, that is ping_err. Since this handler only care
of those icmp errors triggered by echo request, errors triggered
by echo reply(which sent by kernel) are sliently ignored.So wrap ping_err() with icmp_err() to deal with those icmp errors.

Reading /proc/net/snmp on a machine with a lot of cpus is very expensive
(can be ~88000 us).This is because ICMPMSG MIB uses 4096 bytes per cpu, and folding values
for all possible cpus can read 16 Mbytes of memory.ICMP messages are not considered as fast path on a typical server, and
eventually few cpus handle them anyway. We can afford an atomic
operation instead of using percpu data.This saves 4096 bytes per cpu and per network namespace.

Like metrics, the ICMP rate limiting bits are cached state about
a destination. So move it into the inet_peer entries.If an inet_peer cannot be bound (the reason is memory allocation
failure or similar), the policy is to allow.Signed-off-by: David S. Miller

There are ICMP_XXX_STATS that are not used in the kernel, so I remove
them, not to "just patch" them later. But if there's some sense in
keeping them, kick me - I will remake this set keeping them.Signed-off-by: Pavel Emelyanov

icmp_init could fail and this is normal for namespace other than initial.
So, the panic should be triggered only on init_net initialization path.Additionally create rollback path for icmp_init as a separate function.
It will also be used later during namespace destruction.Signed-off-by: Denis V. Lunev

Background: RFC 4293 deprecates existing individual, named ICMP
type counters to be replaced with the ICMPMsgStatsTable. This table
includes entries for both IPv4 and IPv6, and requires counting of all
ICMP types, whether or not the machine implements the type.These patches "remove" (but not really) the existing counters, and
replace them with the ICMPMsgStats tables for v4 and v6.
It includes the named counters in the /proc places they were, but gets the
values for them from the new tables. It also counts packets generated
from raw socket output (e.g., OutEchoes, MLD queries, RA's from
radvd, etc).Changes:
1) create icmpmsg_statistics mib
2) create icmpv6msg_statistics mib
3) modify existing counters to use these
4) modify /proc/net/snmp to add "IcmpMsg" with all ICMP types
listed by number for easy SNMP parsing
5) modify /proc/net/snmp printing for "Icmp" to get the named data
from new counters.Signed-off-by: David L Stevens

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
