d17b136f7d Use C99 style initializers everywhere
This big patch was compiled by vimgrepping for memset calls and changing
to C99 initializer if applicable. One notable exception is the
initialization of union bpf_attr in tc/tc_bpf.c: changing it would break
for older gcc versions (at least <=3.4.6).

Calls to memset for struct rtattr pointer fields for parse_rtattr*()
were just dropped since they are not needed.

The changes here allowed the compiler to discover some unused variables,
so get rid of them, too.

782cf01dc0 ipxfrm: wrong nl msg sent on deleteall cmd
XFRM netlink family is independent from the route netlink family. It's wrong
to call rtnl_wilddump_request(), because it will add a 'struct ifinfomsg' into
the header and the kernel will complain (at least for xfrm state):

netlink: 24 bytes leftover after parsing attributes in process `ip'.

b557416532 xfrm: enable to set non-wildcard mark 0 on SAs and SPs
ip xfrm considers that the user-defined mark is "any" as soon as
(mark.v & mark.m == 0), which prevents from specifying non-wildcard
marks that include the value 0 (typically 0/0xffffffff).

Yet, matching exactly mark 0 is useful for instance to separate
vti policies from global policies.

Always configure the user mark if mark.m != 0.

cbec021913 xfrm: Update documentation
The ip(8) man page and the "ip xfrm [ XFRM-OBJECT ] help" command output
are updated to include missing options, fix errors, and improve grammar.
There are no functional changes made.

The documentation for the ip command has many different meanings for the
same formatting symbols (which really needs to be fixed). This patch makes
consistent use of brackets [ ] to indicate optional parameters, pipes | to
mean "OR", braces { } to group things together, and dashes - instead of
underscores _ inside of parameter names. The parameters are listed in the
order in which they are parsed in the source code.

There are several parameters and options that are still not mentioned or
need to be described more thoroughly in the "COMMAND SYNTAX" section of
the ip(8) man page. I would appreciate help from the developers with this.

de95ae7ca7 xfrm: Allow replay setting
Hi Stephen:

[IP] xfrm: Allow replay setting

For certain applications there is a requirement to start the
sequence number from a point other than the default.  As it
is the kernel provides an interface to do that but it isn't
available through the ip(8) command.  Since we're encouraging
people to migrate over to ip(8) for manual keying, it is useful
to have this ability there.

This patch adds support for setting replay sequence numbers
through ip(8).

Note:
Flush command like `ip xfrm state flush` is to remove all XFRM state.
It has been effected for IPsec SAD but with this patch it flushes both
IPsec SAD and Mobile IPv6 RO states.

af1b6a41d4 Fix struct alignment with cris architecture
[IPROUTE]: Fix struct alignment with cris architecture

gcc for the cris arch does not pad structures to the next multiple of 4
bytes, as the i386 gcc does.

This causes errors like this when displaying xfrm policies:

# ip x p
!!!Deficit 3, rta_len=300
src 192.168.251.32/29 dst 192.168.251.32/29
        dir in priority 0
!!!Deficit 3, rta_len=180
src 0.0.0.0/0 dst 192.168.251.32/29
        dir in priority 2208
....

Similar errors are seen from ip x s.

This patch fixes the errors when printing. I'm not sure whether we
should worry about other uses of the affected structs, I've not seen any
other bad effects from this though, so hopefully this is enough.

(Thanks to Herbert Xu for pointing out that NLMSG_SPACE is the correct
macro to use here.)

Tested against 2.6.17.6 kernel on i386, and 2.6.16.1 kernel on cris.
