When running xfstests with wsize=1024, a number of use-after-free issues
and memory leaks can currently be hit. One of the more obvious
leaks is seen when the generic/013 test fails due to the presence of
sillyrenamed files that never go away.
After testing with kasan enabled, and adding some debugging code to
detect leaked nfs_page and nfs_direct_req structures, I found a number
of issues that appear to be fixed by the following patchset.
Trond Myklebust (10):
NFS: Fix a page leak in nfs_destroy_unlinked_subrequests()
NFS: Fix races nfs_page_group_destroy() vs
nfs_destroy_unlinked_subrequests()
NFS: Fix use-after-free issues in nfs_pageio_add_request()
NFS: Fix a request reference leak in nfs_direct_write_clear_reqs()
NFS: Fix memory leaks in nfs_pageio_stop_mirroring()
NFS: Remove the redundant function nfs_pgio_has_mirroring()
NFS: Clean up nfs_lock_and_join_requests()
NFS: Reverse the submission order of requests in
__nfs_pageio_add_request()
NFS: Refactor nfs_lock_and_join_requests()
NFS: Try to join page groups before an O_DIRECT retransmission
