Di Nitto <fdinitto(a)redhat.com> Date: 2019-10-15 (Tue, 15 Oct 2019) Changed paths: M libknet/host.c Log Message: ----------- [host] fix defrag buffers reclaim logic The problem: - let's assume a 2 nodes (A and B) cluster setup - node A sends fragmented packets to node B and there is packet loss on the network. - node B receives all those fragments and attempts to reassemble them. - node A sends packet seq_num X in Y fragments. - node B receives only part of the fragments and stores them in a defrag buf. - packet loss stops. - node A continues to send packets and a seq_num roll-over takes place. - node A sends a new packet seq_num X in Y fragments. - node B gets confused here because the parts of the old packet seq_num X are still stored and the buffer has not been reclaimed. - node B continues to rebuild packet seq_num X with old stale data and new data from after the roll-over. - node B completes reassembling the packet and delivers junk to the application. The solution: Add a much stronger buffer reclaim logic that will apply on each received packet and not only when defrag buffers are needed, as there might be a mix of fragmented and not fragmented packets in-flight. The new logic creates a window of N packets that can be handled at the same time (based on the number of buffers) and clear everything else.

But in the case where either type was NULL and we assigned an empty string, or type wasn't null but pointing to an empty string we ran into an read-heap-buffer-overflow as here strlen is zero, and so we the first if branch evaluated to > if (pi->paramtype[-1] == '*') { which isn't valid. Depending on the OS, protection of surrounding area due to said OS or the compiler, this can crash the program. Similar issue was the case for the next check for double pointers, here for all strings with strlen < 2. To solve this get the strlen early and check if we cannot underflow before doing the real read.
