ip/netns: use flock when setting up /run/netns
If multiple ip processes are ran at the same time to set up
separate network namespaces, and it is the first time so /run/netns
has to be set up first, and they end up doing it at the same time,
the processes might enter a recursive loop creating thousands of
mount points, which might crash the system depending on resources
available.
Try to take a flock on /run/netns before doing the mount() dance, to
ensure this cannot happen. But do not try too hard, and if it fails
continue after printing a warning, to avoid introducing regressions.
First reported on Debian: https://bugs.debian.org/949235
To reproduce (WARNING: run in a VM to avoid system lockups):
for i in {0..9}
do
strace -e trace=mount -e inject=mount:delay_exit=1000000 ip \
netns add "testnetns$i" 2>&1 | tee "$i.log" &
done
wait
The strace is to ensure the problem always reproduces, to add an
artificial synchronization point after the first mount().

Patch 1 allows adding or removing the Ethernet header.

entire Ethernet frame into MPLS, then add an outer Ethernet header

MAC header of a frame.
Example (encapsulate all outgoing frames with label 20, then add an
outer Ethernet header):
# tc filter add dev ethX matchall \
action mpls mac_push label 20 ttl 64 \
action vlan push_eth dst_mac 0a:00:00:00:00:02 \
src_mac 0a:00:00:00:00:01
This patch also adds an alias for ETH_P_TEB, since it is useful when
decapsulating MPLS packets that contain an Ethernet frame.
With MAC_PUSH, there's no previous Ethertype to modify. However, the
"protocol" option is still needed, because the kernel uses it to set
skb->protocol. So rename can_modify_ethtype() to can_set_ethtype().

iplink: hsr: add support for creating PRP device similar to HSR
This patch enhances the iplink command to add a proto parameters to
create PRP device/interface similar to HSR. Both protocols are
quite similar and requires a pair of Ethernet interfaces. So re-use
the existing HSR iplink command to create PRP device/interface as
well. Use proto parameter to differentiate the two protocols.

iproute2: ip maddress: Check multiaddr length
ip maddress add|del takes a MAC address as argument, so insist on
getting a length of ETH_ALEN bytes. This makes sure the passed argument
is actually a MAC address and especially not an IPv4 address which
was previously accepted and silently taken as a MAC address.
While at it, do not print *argv in the error path as this has been
modified by ll_addr_a2n() and doesn't contain the full string anymore,
which can lead to misleading error messages.
Also while at it, replace the hardcoded buffer size with the actual
buffer size using sizeof().

bridge json fdb show is printing an incorrect / non-machine readable

Add space after format specifier in print_string call. Fixes broken
qdisc tests within tdc testing suite. Per suggestion from Petr Machata,
remove a space and change spacing in tc/q_event.c to complete the fix.
Tested fix in tdc using:

Merge branch 'devlink-port-health' into next
Moshe Shemesh says:
====================
Implement commands for interaction with per-port devlink health
reporters. To do this, adapt devlink-health for usage of port handles
with any existing devlink-health subcommands. Add devlink-port health
subcommand as an alias for devlink-health.
Add devlink port health show subcommand which displays information about
specified port reporter or all present port reporters as in the example.
Device and port reporters can be distinguished by a handle being used.
Make other devlink-health subcommands be aliased by devlink port health.
Refactor devlink-health commands for usage of port handles in order to
interact with port reporters.
Change devlink health show output to dump information about both device
and port reporters with correct handles.
Example:
$ devlink health show
pci/0000:00:0b.0:
reporter fw
state healthy error 0 recover 0 auto_dump true
reporter fw_fatal
state healthy error 0 recover 0 grace_period 1200000 auto_recover true auto_dump true
pci/0000:00:0b.0/1:
reporter tx
state healthy error 0 recover 0 grace_period 10000 auto_recover true auto_dump true
reporter rx
state healthy error 0 recover 0 grace_period 10000 auto_recover true auto_dump true
$ devlink health show pci/0000:00:0b.0/1 reporter rx
Which is equivalent to:
$ devlink port health show pci/0000:00:0b.0/1 reporter rx
pci/0000:00:0b.0/1:
reporter rx
state healthy error 0 recover 0 grace_period 10000 auto_recover true auto_dump true
$ devlink health set pci/0000:00:0b.0/1 reporter rx grace_period 5000
Which is equivalent to:
$ devlink port health set pci/0000:00:0b.0/1 reporter rx grace_period 5000
$ devlink port health show pci/0000:00:0b.0/1 reporter rx
pci/0000:00:0b.0/1:
reporter rx
state healthy error 0 recover 0 grace_period 5000 auto_recover true auto_dump true
