Mauricio Faria de Oliveira a4b41559e5 partitions/aix: fix usage of uninitialized lv_info and lvname structures ... [ Upstream commit 14cb2c8a6c ] The if-block that sets a successful return value in aix_partition() uses 'lvip[].pps_per_lv' and 'n[].name' potentially uninitialized. For example, if 'numlvs' is zero or alloc_lvn() fails, neither is initialized, but are used anyway if alloc_pvd() succeeds after it. So, make the alloc_pvd() call conditional on their initialization. This has been hit when attaching an apparently corrupted/stressed AIX LUN, misleading the kernel to pr_warn() invalid data and hang. [...] partition (null) (11 pp's found) is not contiguous [...] partition (null) (2 pp's found) is not contiguous [...] partition (null) (3 pp's found) is not contiguous [...] partition (null) (64 pp's found) is not contiguous Fixes: 6ceea22bbb ("partitions: add aix lvm partition support files") Signed-off-by: Mauricio Faria de Oliveira <mfo@canonical.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2018-09-19 22:47:15 +02:00
