Date: Sun, 03 Feb 2013 18:31:59 +1000 From: Ben Peddell <klightspeed@...lerwolves.net> To: linux-kernel@...r.kernel.org Subject: [PATCH 0/2] target: OOPS in target_fabric_port_link on v3.7.4 and v3.4.27 There is an OOPS in target_fabric_port_link due to a use before initialization error. commit 0ff8754981261a80f4b77db2536dfea92c2d4539 (target: Add link_magic for fabric allow_link destination target_items) as merged in the linux-3.7.y and linux-3.4.y branches relies on one of the changes that occurred in commit 0fd97ccf45be26fb01b3a412f1f6c6b5044b2f16 (Simplify the code a lot by killing the superflous struct se_subsystem_dev). Without that change, dev is dereferenced before it is initialized. Commit 0fd97ccf45be26fb01b3a412f1f6c6b5044b2f16 looks too invasive, which I would guess would be why it wasn't merged in. One option would be to move the dev->dev_link_magic test to after dev is initialized, as presented the patches I will be following up with. An alternative that will resolve this OOPS is to revert commit fdf9d862969f1be18814273b03fb9497ec2dbdae (target: Add link_magic for fabric allow_link destination target_items) on branch linux-3.7.y, and revert commit 92a7389317838f3338466df0c0e3d23ad33cb1f4 (target: Add link_magic for fabric allow_link destination target_items) on branch linux-3.4.y -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
