[PATCH net 7/7] chtls: Fix chtls resources release sequence
From: Ayush Sawal <ayush.sawal@chelsio.com>
Date: 2021-01-06 04:31:07
Subsystem:
cxgb4 inline crypto driver, networking drivers, the rest · Maintainers:
Ayush Sawal, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
CPL_ABORT_RPL is sent after releasing the resources by calling
chtls_release_resources(sk); and chtls_conn_done(sk);
eventually causing kernel panic. Fixing it by calling release
in appropriate order.
Fixes: cc35c88ae4db ("crypto : chtls - CPL handler definition")
