It is currently impossible to delete individual FDB entries (as opposed to flushing) that were added with a VLAN that no longer exists: # ip link add name dummy1 up type dummy # ip link add name br1 up type bridge vlan_filtering 1 # ip link set dev dummy1 master br1 # bridge fdb add 00:11:22:33:44:55 dev dummy1 master static vlan 1 # bridge vlan del vid 1 dev dummy1 # bridge fdb get 00:11:22:33:44:55 br br1 vlan 1 00:11:22:33:44:55 dev dummy1 vlan 1 master br1 static # bridge fdb del 00:11:22:33:44:55 dev dummy1 master vlan 1 RTNETLINK answers: Invalid argument # bridge fdb get 00:11:22:33:44:55 br br1 vlan 1 00:11:22:33:44:55 dev dummy1 vlan 1 master br1 static This is in contrast to MDB entries that can be deleted after the VLAN was deleted: # bridge vlan add vid 10 dev dummy1 # bridge mdb add dev br1 port dummy1 grp 239.1.1.1 permanent vid 10 # bridge vlan del vid 10 dev dummy1 # bridge mdb get dev br1 grp 239.1.1.1 vid 10 dev br1 port dummy1 grp 239.1.1.1 permanent vid 10 # bridge mdb del dev br1 port dummy1 grp 239.1.1.1 permanent vid 10 # bridge mdb get dev br1 grp 239.1.1.1 vid 10 Error: bridge: MDB entry not found. Align the two interfaces and allow user space to delete FDB entries that were added with a VLAN that no longer exists: # ip link add name dummy1 up type dummy # ip link add name br1 up type bridge vlan_filtering 1 # ip link set dev dummy1 master br1 # bridge fdb add 00:11:22:33:44:55 dev dummy1 master static vlan 1 # bridge vlan del vid 1 dev dummy1 # bridge fdb get 00:11:22:33:44:55 br br1 vlan 1 00:11:22:33:44:55 dev dummy1 vlan 1 master br1 static # bridge fdb del 00:11:22:33:44:55 dev dummy1 master vlan 1 # bridge fdb get 00:11:22:33:44:55 br br1 vlan 1 Error: Fdb entry not found. Add a selftest to make sure this behavior does not regress: # ./rtnetlink.sh -t kci_test_fdb_del PASS: bridge fdb del Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Andy Roulin <aroulin@nvidia.com> Reviewed-by: Petr Machata <petrm@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Link: https://patch.msgid.link/20241105133954.350479-1-idosch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
