Gavrilov Ilia 4865e9fb56 l2tp: fix incorrect parameter validation in the pppol2tp_getsockopt() function ... [ Upstream commit 955e9876ba ] The 'len' variable can't be negative when assigned the result of 'min_t' because all 'min_t' parameters are cast to unsigned int, and then the minimum one is chosen. To fix the logic, check 'len' as read from 'optlen', where the types of relevant variables are (signed) int.
