Hi all,
Issue:
ibv_rc_pingpong with negative size causes segfault
Steps :
run below command :
ibv_rc_pingpong -s -2048
Segmentation fault
Package source :
git://git.kernel.org/pub/scm/libs/infiniband/libibverbs.git
http://www.openfabrics.org/downloads/libibverbs/libibverbs-1.1.4-1.24.gb89d4d7.tar.gz
Solution :
Currently we are not validating the input size passed by user.
Adding input size validation fixes this issue.
Thanks
Vasant
