A user's pathname contains any dot, example /var/www/domain.com/ When executing: su - user It shows this error: ---- jail: can't canonize path "/var/www/domain". Bad path? ---- I found the problem with the function "make_jail_dir", It's in patch multiuser-rsa.patch, but I don't find any info about this problem and why it did make this patch. Reproducible: Always
this is not a regression over current stable
Created attachment 552432 [details, diff] honor standalone '.' in path, split jail dir on "/./" pattern Hello. I suppose this is done in such way so one is able to use the dot pattern "/./" in home path to split jail root from home path in the jail. For example: /home/jail/./home/user/ The function make_jail_dir() checks only for a dot in the path to cut the dir. Proposed patch changes it to search for pattern "/./" only.
