Do not bail out when AF_ALG is not supported by the kernel and
only do so when a map is requested in object ns where we're
calculating the hash. Otherwise, the loader can operate just
fine, therefore lets not fail early when it's not needed.

Kernel now supports attaching XDP programs in the driver
and hardware at the same time. Print that information
correctly.
In case there are multiple programs attached kernel will
not provide IFLA_XDP_PROG_ID, so don't expect it to be
there (this also improves the printing for very old kernels
slightly, as it avoids unnecessary "prog/xdp" line).
In short mode preserve the current outputs but don't print
IDs if there are multiple.
6: netdevsim0: <BROADCAST,NOARP> mtu 1500 xdpoffload/id:11 qdisc [...]
and:
6: netdevsim0: <BROADCAST,NOARP> mtu 1500 xdpmulti qdisc [...]
ip link output will keep using prog/xdp prefix if only one program
is attached, but can also print multiple program lines:
prog/xdp id 8 tag fc7a51d1a693a99e jited
vs:
prog/xdpdrv id 8 tag fc7a51d1a693a99e jited
prog/xdpoffload id 9 tag fc7a51d1a693a99e
JSON output gains a new array called "attached" which will
contain the full list of attached programs along with their
attachment modes:
"xdp": {
"mode": 3,
"prog": {
"id": 11,
"tag": "fc7a51d1a693a99e",
"jited": 0
},
"attached": [ {
"mode": 3,
"prog": {
"id": 11,
"tag": "fc7a51d1a693a99e",
"jited": 0
}
} ]
},
In case there are multiple programs attached the general "xdp"
section will not contain program information:
"xdp": {
"mode": 4,
"attached": [ {
"mode": 1,
"prog": {
"id": 10,
"tag": "fc7a51d1a693a99e",

}
},{

Jesus Sanchez-Palencia says:
====================
fixes since v3:
- Add support for clock names with the "CLOCK_" prefix;
- Print clock name on print_opt();
- Use strcasecmp() instead of strncasecmp().
The ETF (earliest txtime first) qdisc was recently merged into net-next
[1], so this patchset adds support for it through the tc command line
tool.
An initial man page is also provided.
The first commit in this series is adding an updated version of
include/uapi/linux/pkt_sched.h and is not meant to be merged. It's
provided here just as a convenience for those who want to easily build
this patchset.

Add support for configuration parameters set and show.
Each parameter can be either generic or driver-specific.
The user can retrieve data on these configuration parameters by devlink
param show command and can set new value to a configuration parameter
by devlink param set command.
The configuration parameters can be set in different configuration
modes:
runtime - set while driver is running, no reset required.
driverinit - applied while driver initializes, requires restart
driver by devlink reload command.
permanent - written to device's non-volatile memory, hard reset
required to apply.
New commands added:
devlink dev param show [DEV name PARAMETER]
devlink dev param set DEV name PARAMETER value VALUE

Currently, calling 'ip xfrm monitor all' will
actually invoke the 'all-nsid' command because the
soft-match for 'all-nsid' occurs before the precise
match for 'all'. This patch rearranges the checks
so that the 'all' command, itself an alias for
invoking 'ip xfrm monitor' with no argument, can
be called consistent with the syntax for other ip
commands that accept an 'all'.

A recent commit changed rtnl_talk_* to return the response message in
allocated memory so callers need to free it. The change to name_is_vrf
did not save the device index which is pointing to a struct inside the
now allocated and freed memory resulting in garbage getting returned
in some cases.
Fix by using a stack variable to save the return value and only set
it to ifi->ifi_index after all checks are done and before the answer
buffer is freed.
