CVE-2024-56779: nfsd: fix nfs4_openowner leak when concurrent nfsd4_open occur

In the Linux kernel, the following vulnerability has been resolved:

nfsd: fix nfs4openowner leak when concurrent nfsd4open occur

The action force umount(umount -f) will attempt to kill all rpctask even umount operation may ultimately fail if some files remain open. Consequently, if an action attempts to open a file, it can potentially send two rpctask to nfs server.

NFS CLIENT thread1 thread2 open("file") ... nfs4doopen nfs4doopen nfs4openandgetstate nfs4procopen nfs4runopentask / rpctask1 / rpcruntask rpcwaitforcompletiontask

umount -f nfsumountbegin rpckillalltasks rpcsignaltask rpctask1 been wakeup and return -512 nfs4doopen // while loop ... nfs4runopentask / rpctask2 / rpcruntask rpcwaitforcompletiontask

While processing an open request, nfsd will first attempt to find or allocate an nfs4openowner. If it finds an nfs4openowner that is not marked as NFS4OOCONFIRMED, this nfs4openowner will released. Since two rpctask can attempt to open the same file simultaneously from the client to server, and because two instances of nfsd can run concurrently, this situation can lead to lots of memory leak. Additionally, when we echo 0 to /proc/fs/nfsd/threads, warning will be triggered.

NFS SERVER nfsd1 nfsd2 echo 0 > /proc/fs/nfsd/threads
