From 555c592304023a0d24216a6d8ed9d525602ae218 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Thu, 30 Aug 2018 15:08:20 +0200 Subject: [PATCH] ppp: remove hardcoded lcp-echo-failure, lcp-echo-interval values OpenWrt used to ship hardcoded defaults for lcp-echo-failure and lcp-echo-interval in the non-uci /etc/ppp/options file. These values break uci support for *disabling* LCP echos through the use of "option keepalive 0" as either omitting the keepalive option or setting it to 0 will result in no lcp-echo-* flags getting passed to the pppd cmdline, causing the pppd process to revert to the defaults in /etc/ppp/options. Address this issue by letting the uci "keepalive" option default to the former hardcoded values "5, 1" and by removing the fixed lcp-echo-failure and lcp-echo-interval settings from the /etc/ppp/options files.
