Adding Dave Miller to the thread. commit fbf8e7211ac7858d3df4a4203c18da7a58560784 Author: Shuah Khan Date: Tue Nov 11 10:04:13 2014 -0700 selftests/net: psock_fanout seg faults in sock_fanout_read_ring() The while loop in sock_fanout_read_ring() checks mmap region bounds after access, causing it to segfault. Fix it to check count before accessing header->tp_status. This problem can be reproduced consistently when the test in run as follows: make -C tools/testing/selftests TARGETS=net run_tests or make run_tests from tools/testing/selftests or make run_test from tools/testing/selftests/net Signed-off-by: Shuah Khan Signed-off-by: David S.
