From 9ccfbb841c01b1d15270374a3ce07641267b730d Mon Sep 17 00:00:00 2001 From: John Crispin Date: Fri, 3 Apr 2015 19:06:45 +0000 Subject: [PATCH] ppp: Fix seg fault when using pppol2tp PPPD crashes (SEGV) when the dump or dryrun options are specified and an option is internally defined as "o_special" with an option flag of "OPT_A2STRVAL". As the option value is not saved when the parameter is processed, a reference to the option will result into a crash (e.g. when printing).
