after set SO_DONTROUTE to 1, the IP layer should not route packets if
the dest IP address is not in link scope. But if the socket has cached
the dst_entry, such packets would be routed until the sk_dst_cache
expires. So we should clean the sk_dst_cache when a user set
SO_DONTROUTE option. Below are server/client python scripts which
could reprodue this issue:
server side code:
==========================================================================
import socket
import struct
import time
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('0.0.0.0', 9000))
s.listen(1)
sock, addr = s.accept()
sock.setsockopt(socket.SOL_SOCKET, socket.SO_DONTROUTE, struct.pack('i', 1))
while True:
sock.send(b'foo')
time.sleep(1)
==========================================================================
client side code:
==========================================================================
import socket
import time
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('server_address', 9000))
while True:

The existing garbage collection algorithm has a number of problems:
1. The gc algorithm will not evict PERMANENT entries as those entries
are managed by userspace, yet the existing algorithm walks the entire
hash table which means it always considers PERMANENT entries when
looking for entries to evict. In some use cases (e.g., EVPN) there
can be tens of thousands of PERMANENT entries leading to wasted
CPU cycles when gc kicks in. As an example, with 32k permanent
entries, neigh_alloc has been observed taking more than 4 msec per
invocation.
2. Currently, when the number of neighbor entries hits gc_thresh2 and
the last flush for the table was more than 5 seconds ago gc kicks in
walks the entire hash table evicting *all* entries not in PERMANENT
or REACHABLE state and not marked as externally learned. There is no
discriminator on when the neigh entry was created or if it just moved
from REACHABLE to another NUD_VALID state (e.g., NUD_STALE).
It is possible for entries to be created or for established neighbor
entries to be moved to STALE (e.g., an external node sends an ARP
request) right before the 5 second window lapses:
-----|---------x|----------|-----
t-5 t t+5
If that happens those entries are evicted during gc causing unnecessary
thrashing on neighbor entries and userspace caches trying to track them.
Further, this contradicts the description of gc_thresh2 which says
"Entries older than 5 seconds will be cleared".
One workaround is to make gc_thresh2 == gc_thresh3 but that negates the
whole point of having separate thresholds.
3. Clearing *all* neigh non-PERMANENT/REACHABLE/externally learned entries
when gc_thresh2 is exceeded is over kill and contributes to trashing
especially during startup.
This patch addresses these problems as follows:
1. Use of a separate list_head to track entries that can be garbage
collected along with a separate counter. PERMANENT entries are not
added to this list.
The gc_thresh parameters are only compared to the new counter, not the
total entries in the table. The forced_gc function is updated to only
walk this new gc_list looking for entries to evict.
2. Entries are added to the list head at the tail and removed from the
front.
3. Entries are only evicted if they were last updated more than 5 seconds
ago, adhering to the original intent of gc_thresh2.
4. Forced gc is stopped once the number of gc_entries drops below
gc_thresh2.
5. Since gc checks do not apply to PERMANENT entries, gc levels are skipped
when allocating a new neighbor for a PERMANENT entry. By extension this
means there are no explicit limits on the number of PERMANENT entries
that can be created, but this is no different than FIB entries or FDB
entries.

This patch adds handling for HNS3 hardware errors(non-standard)
which are reported through MSIX interrupts and not through
PCIe AER channel.
These MSIX reported hardware errors are handled using common
misc. interrupt handler. Hardware error related registers
cannot be cleared in context to the interrupt received as
they require *heavy* access to hardware using IMP(Integrated
Mangement Processor) commands. Hence, we defer the clearing
of such error events till later time.
Since, we have defered exact identification of errors we
will have to defer the level of receovery/reset which
might be required. Hence, a new reset type UNKNOWN reset
has been introduced which effectively defers the assertion
of the reset till we get hold of kind of errors at later
time.

mlxsw: Un/offload FDB on NVE detach/attach
Petr says:
When a VXLAN device is attached to a bridge of a driver capable of
offloading such, or upped, the FDB entries already present at the device
need to be offloaded. Similarly when an offloaded VXLAN device ceases
being interesting (it is downed, or detached, or a front-panel port
netdevice is detached from the bridge that the VXLAN device is attached
to), any offloaded FDB entries need to be unoffloaded and unmarked. This
attach / detach processing is implemented in this patchset.
In patch #1, a code pattern is extracted into a named function for
easier reuse.
In patch #2, vxlan_fdb_replay() is added to send
SWITCHDEV_VXLAN_FDB_ADD_TO_DEVICE for each FDB entry with a given VNI.
The intention is that the offloading driver will interpret these events
like any other and thus offload the FDB entries that existed prior to
VXLAN attach.
In patches #3 and #4, the functions vxlan_fdb_clear_offload() resp.
br_fdb_clear_offload() are added. These clear the offloaded flag at
matching FDB entries.
In patches #5-#9, we introduce FID-type-specific and NVE-type-specific
ops necessary to properly abstract invocations of the replay/clear
functions.
Finally patch #10 implements the FDB management.
In patch #11, the mlxsw-specific test case is extended to check that the
management of offload marks under the newly-supported situations is
correct. Patch #12, from Ido, exercises the new code paths in actual
functional test.
v2:
- Patch #1:
- Modify vxlan_fdb_switchdev_notifier_info() to initialize the
structure through a passed-in pointer argument, instead of returning
it as a value.
- Patch #2:
- Adapt to API change in vxlan_fdb_switchdev_notifier_info()

When a VXLAN device is attached to an offloaded bridge, or when a
front-panel port is attached to a bridge that already has a VXLAN
device, mlxsw should offload the existing offloadable FDB entries.
Similarly when VXLAN device is downed, the FDB entries are unoffloaded,
and the marks thus need to be cleared. Similarly when a front-panel port
device is attached to a bridge with a VXLAN device, or when VLAN flags
are tweaked on a VXLAN port attached to a VLAN-aware bridge.

When NVE is disabled on a FID, any existing FDB offloaded marks need to

Petr Machata says:
====================
Pass extack to NETDEV_PRE_UP
Drivers may need to validate configuration of a device that's about to
be upped. An example is mlxsw, which needs to check the configuration of
a VXLAN device attached to an offloaded bridge. Should the validation
fail, there's currently no way to communicate details of the failure to
the user, beyond an error number.
Therefore this patch set extends the NETDEV_PRE_UP event to include
extack, if available.
There are three vectors through which NETDEV_PRE_UP invocation can be
reached. The two major ones are dev_open() and dev_change_flags(), the
last is then __dev_change_flags().
In patch #1, the first access vector, dev_open() is addressed. An extack
parameter is added and all users converted to use it.
Before addressing the second vector, two preparatory patches propagate
extack argument to the proximity of the dev_change_flags() call in VRF
and IPVLAN drivers. That happens in patches #2 and #3. Then in patch #4,
dev_change_flags() is treated similarly to dev_open().
Likewise in patch #5, __dev_change_flags() is extended.
Then in patches #6 and #7, the extack is finally propagated all the way
to the point where the notification is emitted.
This change allows particularly mlxsw (which already has code to
leverage extack if available) to communicate to the user error messages
regarding VXLAN configuration. In patch #8, add a test case that
exercises this code and checks that an error message is propagated.
For example:
local 192.0.2.17 remote 192.0.2.18 \
dstport 4789 nolearning noudpcsum tos inherit ttl 100
local 192.0.2.17 remote 192.0.2.18 \

A follow-up patch will extend dev_change_flags() with an extack
argument. Extend ipvlan_set_port_mode() to have that argument available
for the conversion.

In order to pass extack together with NETDEV_PRE_UP notifications, it's
necessary to route the extack to __dev_open() from diverse (possibly
indirect) callers. One prominent API through which the notification is
invoked is dev_open().
Therefore extend dev_open() with and extra extack argument and update
all users. Most of the calls end up just encoding NULL, but bond and
team drivers have the extack readily available.

Andrew Lunn says:
====================
Adjust MTU of DSA master interface
DSA makes use of additional headers to direct a frame in/out of a
specific port of the switch. When the slave interfaces uses an MTU of
1500, the master interface can be asked to handle frames with an MTU
of 1504, or 1508 bytes. Some Ethernet interfaces won't
transmit/receive frames which are bigger than their MTU.
Automate the increasing of the MTU on the master interface, by adding
to each tagging driver how much overhead they need, and then calling
dev_set_mtu() of the master interface to increase its MTU as needed.
