From 296012285c908f6aacea83913ab9eaf273225d57 Mon Sep 17 00:00:00 2001 From: James Smart Date: Wed, 14 Aug 2019 16:56:36 -0700 Subject: [PATCH] scsi: lpfc: Fix leak of ELS completions on adapter reset If the adapter is reset while there are outstanding ELS's, subsequent reinitialization of the adapter will fail as it has not recovered all of the io contexts relative to the ELS's. If an ELS timed out or otherwise failed and an the ELS was attempted to be aborted (which changes the ELS completion context), in causes where the driver generates completions for the outstanding IO as the adapter would not due to being reset, the driver released only the ELS context and failed to release the abort context. When the adapter went to reinit, as it had not received all of the contexts, it failed to reinit. Fix by having the ELS completion handler identify the driver-generated completion status and release the abort context. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Signed-off-by: Martin K.
