In commit 6f4bfed3a ("MINOR: server: Add parser support for
set-proxy-v2-tlv-fmt") a suspicious check for a NULL srv_tlv was placed
in the list_for_each_entry(), that should not be needed. In practice,
it's caused by the list head not being initialized, hence the first
element is NULL, as shown by Alexander's reproducer below which crashes
if the test in the loop is removed:
backend dummy
default-server send-proxy-v2 set-proxy-v2-tlv-fmt(0xE1) %[fc_pp_tlv(0xE1)]
server dummy_server 127.0.0.1:2319
The right place to initialize this field is proxy_preset_defaults().
We'd really need a function to initialize a server :-/
The check in the loop was removed. No backport is needed.
