Prabhath Sajeepa 412b7023b8 nvme-rdma: Avoid double freeing of async event data ... [ Upstream commit 9134ae2a25 ] The timeout of identify cmd, which is invoked as part of admin queue creation, can result in freeing of async event data both in nvme_rdma_timeout handler and error handling path of nvme_rdma_configure_admin queue thus causing NULL pointer reference. Call Trace: ? nvme_rdma_setup_ctrl+0x223/0x800 [nvme_rdma] nvme_rdma_create_ctrl+0x2ba/0x3f7 [nvme_rdma] nvmf_dev_write+0xa54/0xcc6 [nvme_fabrics] __vfs_write+0x1b/0x40 vfs_write+0xb2/0x1b0 ksys_write+0x61/0xd0 __x64_sys_write+0x1a/0x20 do_syscall_64+0x60/0x1e0 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Reviewed-by: Roland Dreier <roland@purestorage.com> Reviewed-by: Max Gurtovoy <maxg@mellanox.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Prabhath Sajeepa <psajeepa@purestorage.com> Signed-off-by: Keith Busch <kbusch@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-04-13 10:44:58 +02:00
