The help text was misleading: One could think it is possible to list
rules by selector, which would be nice but isn't. This change also
clarifies that 'ip rule' defaults to 'list' if no further arguments are
given.

Add IFLA_VF_TRUST message to trust the VF.
PF can accept some privileged operation from the trusted VF.
For example, ixgbe PF doesn't allow to enable VF promiscuous mode until
the VF is trusted because it may hurt performance.

To trust VF.
 # ip link set dev eth0 vf 1 trust on

To untrust VF.
 # ip link set dev eth0 vf 1 trust off

This patch is a follow up to the recently added
'static' fdb option.

It introduces a new option 'dynamic' which adds
dynamic fdb entries with NUD_REACHABLE.

$bridge fdb add 00:01:02:03:04:06 dev eth0 master dynamic

$bridge fdb show
00:01:02:03:04:06 dev eth0

This patch also documents all fdb types. Removes 'temp'
from usage message since it is now replaced by 'static'.
'temp' still works and is synonymous with static.

netns_map_add() does a malloc of (sizeof (struct nsid_cache) +
strlen(name)) and then proceed with strcpy() of name into the
zero-length member at the end of the nsid_cache structure.  The
nul-terminator is written outside of the allocated memory and may
overwrite the allocator's internal structure.

This can trigger a segmentation fault on i386 uclibc with names of size 8:
after the corruption occurs, the call to closedir() on netns_map_init()
crashes while freeing the DIR structure.

There is no intuitive option to add static fdb entries today.
'temp' seems to have a side effect of adding
'static' fdb entries. But the name and intent
of 'temp' does not say anything about it being static.

example:
bridge fdb add operates as follows:

$bridge fdb add 00:01:02:03:04:05 dev eth0 master
$bridge fdb add 00:01:02:03:04:06 dev eth0 master temp
$bridge fdb add 00:01:02:03:04:07 dev eth0 master local

$bridge fdb show
00:01:02:03:04:05 dev eth0 permanent
00:01:02:03:04:06 dev eth0 static
00:01:02:03:04:07 dev eth0 permanent
00:01:02:03:04:08 dev eth0 <<== dynamic, ageable learned mac

This patch adds a new bridge fdb type 'static' which
makes sure NUD_NOARP and NUD_REACHABLE is set for static
entries. This effectively is nothing but what 'temp'
does today. But the name 'temp' is misleading.

After the patch:
$bridge fdb add 00:01:02:03:04:06 dev eth0 master static

$bridge fdb show
00:01:02:03:04:06 dev eth0 static

'temp' could ideally be a dynamic mac that can age (ie just
NUD_REACHABLE). But, 'temp' sets 'NUD_NOARP' and 'NUD_REACHABLE'.
Too late to change 'temp' now. But, we are thinking of introduing a
'dynamic' keyword after this patch that only sets NUD_REACHABLE.

Provide some more hints to the user/developer when relos have been found
that don't point to ld64 imm instruction. Ran couple of times into relos
generated by clang [1], where the compiler tried to uninline inlined
functions with eBPF and emitted BPF_JMP | BPF_CALL opcodes. If this seems
the case, give a hint that the user should do a work-around to use
always_inline annotation.
