TLS module crash while running SSL record encryption using
klts_send_[file] using crypto accelerator (Nitrox).
Following are the preconditions and steps to reproduce the issue:
Preconditions:
1) Installed 5.3-rc4
2) Nitrox5 card plugin (crypto accelerator)
Steps to reproduce the issue:
1) Installed n5pf.ko (drivers/crypto/cavium/nitrox)
2) Installed tls.ko if not is installed by default (net/tls)
3) Obtained uperf tool from GitHub
3.1) Modified uperf to use tls module by using setsocket.
3.2) Modified uperf tool to support sendfile with SSL.
Test:
1) Ran uperf with 4 threads
2) Each thread sends data using sendfile over SSL protocol.
After a few seconds into the test, kernel crashes because of record
list corruption
