[hardy] proftpd crashes when used directive <Class> with netmask

[Igor Goldenberg]

I have standalone proftpd server. After upgrading to 8.04 (from 7.10) server begins to crash while users connect. At this time in proftpd.log I have:

May 04 12:08:53 ftp proftpd[24516] ftp.454.ru (195.200.95.33[195.200.95.33]): ProFTPD terminating (signal 11)
May 04 12:08:53 ftp proftpd[24516] ftp.454.ru (195.200.95.33[195.200.95.33]): FTP session closed.
May 04 12:09:02 ftp proftpd[24537] ftp.454.ru (195.200.95.33[195.200.95.33]): ProFTPD terminating (signal 11)
May 04 12:09:02 ftp proftpd[24537] ftp.454.ru (195.200.95.33[195.200.95.33]): FTP session closed.

After digging in my .conf file I found a reason of crashes: line 'From 10.0.0.0/8' in <Class> block. Changing /8 to any other suffix changes nothing but just 10.0.0.0 (or any other single IP) works well. Also any address with mask suffix causes crash. But after rebuilding proftpd from sources with excluded 'class_rules_fix.dpatch' from directive with mask again works well as before.

So I think patch 'class_rules_fix' has some bugs.
