Subject: [PATCH 1/3] scsi: libiscsi: move init ehwait to iscsi_session_setup()
Date: Thu,  9 Sep 2021 23:47:27 +0800	[thread overview]
Message-ID: <> (raw)

commit ec29d0ac29be ("scsi: iscsi: Fix conn use after free during
resets") move member ehwait from conn to session, but left init ehwait
in iscsi_conn_setup().

Due to one session can be binded by multi conns, the conn after the
first will reinit the session->ehwait, move init ehwait to
iscsi_session_setup() to fix it.

Fixes: ec29d0ac29be ("scsi: iscsi: Fix conn use after free during resets")
