Destroying a Xen guest domain while it was doing I/Os via xen-blkback leaked several resources, including references of the guest's memory pages. This patch series addresses those leaks by correcting usage of reference counts and the sequence when to free which resource. The series applies on top of commit 2d4456c73a487abe ("block: xen-blkback: add null check to avoid null pointer dereference") in Jens Axboe's tree kernel/git/axboe/linux-block.git Juergen Gross (3): xen/blkback: fix disconnect while I/Os in flight xen/blkback: don't free be structure too early xen/blkback: don't use xen_blkif_get() in xen-blkback kthread drivers/block/xen-blkback/blkback.c | 3 --- drivers/block/xen-blkback/common.h | 1 + drivers/block/xen-blkback/xenbus.c | 15 ++++++++------- 3 files changed, 9 insertions(+), 10 deletions(-) -- 2.12.0 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
