Remi Tricot-Le Breton bc2c386992 BUG/MINOR: ssl: Prevent removal of crt-list line if the instance is a default one
If the first active line of a crt-list file is also the first mentioned
certificate of a frontend that does not have the strict-sni option
enabled, then its certificate will be used as the default one. We then
do not want this instance to be removable since it would make a frontend
lose its default certificate.
Considering that a crt-list file can be used by multiple frontends, and
that its first mentioned certificate can be used as default certificate
for only a subset of those frontends, we do not want the line to be
removable for some frontends and not the others. So if any of the ckch
instances corresponding to a crt-list line is a default instance, the
removal of the crt-list line will be forbidden.

It can be backported as far as 2.2.

#REGTEST_TYPE=devel
# This reg-test uses the "del ssl crt-list" command to remove a line from a crt-list.
# It performs three requests towards a frontend that uses simple.crt-list.
# Between the second and third requests, a line is deleted from the crt-list,
# which makes the third request fail since it would have used the deleted line
# and the strict-sni option is enabled on the frontend.
# Another test is performed as well. A line corresponding to the default instance
# of a frontend that does not have the strict-sni option enabled cannot be deleted.
