Subject: [PATCH net v3 0/4] Unsync addresses from ports when stopping aggregated devices
Date: Wed,  7 Sep 2022 16:56:38 +0900	[thread overview]
Message-ID: <20220907075642.475236-1-bpoirier@nvidia.com> (raw)

This series fixes similar problems in the bonding and team drivers.

Because of missing dev_{uc,mc}_unsync() calls, addresses added to
underlying devices may be leftover after the aggregated device is deleted.
Add the missing calls and a few related tests.

v2:
* fix selftest installation, see patch 3

v3:
* Split lacpdu_multicast changes to their own patch, #1
* In ndo_{add,del}_slave methods, only perform address list changes when
  the aggregated device is up (patches 2 & 3)
* Add selftest function related to the above change (patch 4)

      net: Add tests for bonding and team address list management · bbb774d9
      Benjamin Poirier authored 
      Test that the bonding and team drivers clean up an underlying device's
address lists (dev->uc, dev->mc) when the aggregated device is deleted.

Test addition and removal of the LACPDU multicast address on underlying
devices by the bonding driver.

v2:
* add lag_lib.sh to TEST_FILES

v3:
* extend bond_listen_lacpdu_multicast test to init_state up and down cases
* remove some superfluous shell syntax and 'set dev ... up' commands

      net: team: Unsync device addresses on ndo_stop · bd602342
      Benjamin Poirier authored 
      Netdev drivers are expected to call dev_{uc,mc}_sync() in their
ndo_set_rx_mode method and dev_{uc,mc}_unsync() in their ndo_stop method.
This is mentioned in the kerneldoc for those dev_* functions.

The team driver calls dev_{uc,mc}_unsync() during ndo_uninit instead of
ndo_stop. This is ineffective because address lists (dev->{uc,mc}) have
already been emptied in unregister_netdevice_many() before ndo_uninit is
called. This mistake can result in addresses being leftover on former team
ports after a team device has been deleted; see test_LAG_cleanup() in the
last patch in this series.

Add unsync calls at their expected location, team_close().

v3:
* When adding or deleting a port, only sync/unsync addresses if the team
  device is up. In other cases, it is taken care of at the right time by
  ndo_open/ndo_set_rx_mode/ndo_stop.

Add unsync calls, via bond_hw_addr_flush(), at their expected location,
bond_close().
Add dev_mc_add() call to bond_open() to match the above change.

v3:
* When adding or deleting a slave, only sync/unsync, add/del addresses if
  the bond is up. In other cases, it is taken care of at the right time by
  ndo_open/ndo_set_rx_mode/ndo_stop.

      There are already a few definitions of arrays containing
MULTICAST_LACPDU_ADDR and the next patch will add one more use. These all
contain the same constant data so define one common instance for all
bonding code.

====================
Intel Wired LAN Driver Updates 2022-09-08 (ice, iavf)

This series contains updates to ice and iavf drivers.

Dave removes extra unplug of auxiliary bus on reset which caused a
scheduling while atomic to be reported for ice.

Ding Hui defers setting of queues for TCs to ensure valid configuration
and restores old config if invalid for ice.

Sylwester fixes a check of setting MAC address to occur after result is
received from PF for iavf driver.

Brett changes check of ring tail to use software cached value as not all
devices have access to register tail for iavf driver.

      net/ieee802154: fix uninit value bug in dgram_sendmsg · 94160108
      Haimin Zhang authored 
      There is uninit value bug in dgram_sendmsg function in
net/ieee802154/socket.c when the length of valid data pointed by the
msg->msg_name isn't verified.

We introducing a helper function ieee802154_sockaddr_check_size to
check namelen. First we check there is addr_type in ieee802154_addr_sa.
Then, we check namelen according to addr_type.

Also fixed in raw_bind, dgram_bind, dgram_connect.
