From 28e9dcd9172028263c8225c15c4e329e08475e89 Mon Sep 17 00:00:00 2001 From: Vinay Kumar Yadav Date: Mon, 26 Oct 2020 01:05:39 +0530 Subject: chelsio/chtls: fix deadlock issue In chtls_pass_establish() we hold child socket lock using bh_lock_sock and we are again trying bh_lock_sock in add_to_reap_list, causing deadlock. Remove bh_lock_sock in add_to_reap_list() as lock is already held.
