[OpenWrt-Devel] [PATCH 05/10] kernel: Activate CONFIG_SYN_COOKIES for all targets

Fri May 3 13:52:02 PDT 2019


Some targets deactivated CONFIG_SYN_COOKIES, for unknown reasons, use
the default setting from the generic configuration which activates
CONFIG_SYN_COOKIES.

This should prevent SYN flooding.
