Subject: RE: general protection fault in dst_dev_put (2)
Date: Wed, 20 Mar 2019 15:43:49 +0000 [thread overview]
Message-ID: <BL0PR1501MB200344EF36F7E6EFCE435F4E9A410@BL0PR1501MB2003.namprd15.prod.outlook.com> (raw)
In-Reply-To: <00000000000060a659058475c57e@google.com>
This one points to a bug that was fixed in commit dc4501ff2875 ("tipc: fix a double free in tipc_enable_bearer()").
That commit was applied to 4.20, but is not present in 4.16, which caused this dump.
To get further with this I need a dump of the actual crash in 4.20 or 5.0.
Maybe we are looking at two different problems here?
