From: blogic Date: Fri, 3 Apr 2015 19:06:45 +0000 (+0000) Subject: ppp: Fix seg fault when using pppol2tp X-Git-Url: http://207.154.207.93/?a=commitdiff_plain;h=98b2e7938e63704f1ae91eb71da2567c6dbeccac;p=openwrt.git 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).
