Dear release team,
We experienced (in production) a bug in OVS which lead to ovs-vswitchd
being killed, leading to network downtime in our OpenStack environment.
Attached is the fix. I wish to upload this update to Buster.
On top of this upstream fix, a small typo fix in ifupdown.sh.
Please let me upload
openvswitch/2.10.0+2018.08.28+git.8ca7c82b7d+ds1-12+deb10u2
Cheers,
Thomas Goirand (zigo)

+Description: connmgr: Fix vswitchd abort when a port is added and the
controller is down
+ We see the below trace when a port is added to a bridge and the configured
+ controller is down
+ .
+ 0x00007fb002f8b207 in raise () from /lib64/libc.so.6
+ 0x00007fb002f8c8f8 in abort () from /lib64/libc.so.6
+ 0x00007fb004953026 in ofputil_protocol_to_ofp_version () from
/lib64/libopenvswitch-2.10.so.0
+ 0x00007fb00494e38e in ofputil_encode_port_status () from
/lib64/libopenvswitch-2.10.so.0
+ 0x00007fb004ef1c5b in connmgr_send_port_status () from
/lib64/libofproto-2.10.so.0
+ 0x00007fb004efa9f4 in ofport_install () from /lib64/libofproto-2.10.so.0
+ 0x00007fb004efbfb2 in update_port () from /lib64/libofproto-2.10.so.0
+ 0x00007fb004efc7f9 in ofproto_port_add () from /lib64/libofproto-2.10.so.0
+ 0x0000556d540a3f95 in bridge_add_ports__ ()
+ 0x0000556d540a5a47 in bridge_reconfigure ()
+ 0x0000556d540a9199 in bridge_run ()
+ 0x0000556d540a02a5 in main ()
+ .
+ The abort is because of ofputil_protocol_to_ofp_version() is called with
invalid
+ protocol - OFPUTIL_P_NONE. Please see [1] for more details. Similar aborts are
+ seen as reported in [2].
+ .
+ The commit [3] changed the behavior of the function rconn_get_version().
+ Before the commit [3], the function ofconn_receives_async_msg() would always
+ return false if the connection to the controller was down, since
+ rconn_get_version() used to return -1. This patch now checks the rconn
+ connection status in ofconn_receives_async_msg() and returns false if not
+ connected. This would avoid the aborts seen in the above stack trace.
+ .
+ The issue can be reproduced by running the test added in this patch
+ without the fix.
+ .
