Marc Kleine-Budde 45221a57b6 can: isotp: convert struct tpcon::{idx,len} to unsigned int ... commit 5f33a09e769a9da0482f20a6770a342842443776 upstream. In isotp_rcv_ff() 32 bit of data received over the network is assigned to struct tpcon::len. Later in that function the length is checked for the maximal supported length against MAX_MSG_LENGTH. As struct tpcon::len is an "int" this check does not work, if the provided length overflows the "int". Later on struct tpcon::idx is compared against struct tpcon::len. To fix this problem this patch converts both struct tpcon::{idx,len} to unsigned int.
