Like kernel net-next commit 72f6d71e491e6 ("vxlan: add ttl inherit support"),
vxlan ttl inherit should means inherit the inner protocol's ttl value.
But currently when we add vxlan with "ttl inherit", we only set ttl 0,
which is actually use whatever default value instead of inherit the inner
protocol's ttl value.
To make a difference with ttl inherit and ttl == 0, we add an attribute
IFLA_VXLAN_TTL_INHERIT when "ttl inherit" specified. And use "ttl auto"
to means "use whatever default value", the same behavior with ttl == 0.

Thomas reported a change in behavior with respect to autodectecting
address families. Specifically, 'ip ro add default via fe80::1'
syntax was failing to treat fe80::1 as an IPv6 address as it did in
prior releases. The root causes appears to be a change in family when
the default keyword is parsed.
'default', 'any' and 'all' are relevant outside of AF_INET. Leave the
family arg as is for these when setting addr.

Attempt to add a multipath route where a nexthop definition refers to a

The offset and peer_offset parameters are only printed to avoid

Commit 9fd3f0b255 ("tc: enable json output for actions") added JSON
support for tc-actions at the expense of breaking other use cases that
reach tc_print_action(), as the latter don't expect the 'actions' array
to be a new object.
Consider the following taken duringrun of tc_chain.sh selftest,
and see the latter command output is broken:
$ ./tc/tc -j -p actions list action gact | grep -C 3 actions
[ {
"total acts": 1
},{
"actions": [ {
"order": 0,
$ ./tc/tc -p -j -s filter show dev enp3s0np2 ingress | grep -C 3 actions
},
"skip_hw": true,
"not_in_hw": true,{
"actions": [ {
"order": 1,
"kind": "gact",
"control_action": {
Relocate the open/close of the JSON object to declare the object only
for the case that needs it.

Ignore options "peer-offset" and "offset" when creating sessions. Keep
them when dumping sessions in order to avoid breaking external scripts.
"peer-offset" has always been a noop in iproute2. "offset" is now
ignored in Linux 4.16 (and was broken before that).

====================
This series enhances the iproute2 rdma tool to include dumping of
connection manager id (cm_id), completion queue (cq), memory region (mr),
and protection domain (pd) rdma resources. It is the user-space part of
the kernel resource tracking series merged into rdma-next for 4.17 [1]
and [2].
Changes since v3:
- replaced rdma_cma.h inclusion with UAPI rdma_user_cm.h
- display only device names instead of device/port for cq, mr, and pd
since they are not associated with a specific port.
Changes since v2:
- pull in rdma-core:include/rdma/rdma_cma.h
- 80 column reformat
- add reviewed-by tags
Changes since v1/RFC:
- removed RFC tag
- initialize rd properly to avoid passing a garbage port number
- revert accidental change to qp_valid_filters
- removed cm_id dev/network/transport types
- cm_id ip addrs now passed up as __kernel_sockaddr_storage
- cm_id ip address ports printed as "address:port" strings
- only parse/display memory keys and iova if available
- filter on "users" for cqs and pds
- fixed memory leaks
- removed PD_FLAGS attribute
- filter on "mrlen" for mrs
- filter on "poll-ctx" for cqs
- don't require addrs or qp_type for parsing cm_ids
- only filter optional attrs if they are present
- remove PGSIZE MR attr to match kernel
