Mounting NFSv3 uses default timeout parameters specified by underlying
sunrpc transport, and mount options like 'timeo' and 'retrans', unlike
NFSv4, are not honored.
But sometimes we want to set non-default timeout value when mounting
NFSv3, so pass 'timeo' and 'retrans' to nfs_mount() and fill the
'timeout' field of struct rpc_create_args before creating RPC
connection. This is also consistent with NFSv4 behavior.
Note that this only sets the timeout value of rpc connection to mountd,
but the timeout of rpcbind connection should be set as well. A later
patch will fix the rpcbind part.

Currently rpcbind client is created without setting rpc timeout (thus

Fix shift out-of-bounds in xprt_calc_majortimeo(). This is caused
by a garbage timeout (retrans) mount option being passed to nfs mount,
in this case from syzkaller.
If the protocol is XPRT_TRANSPORT_UDP, then 'retrans' is a shift
value for a 64-bit long integer, so 'retrans' cannot be >= 64.
If it is >= 64, fail the mount and return an error.

The cached NFSv3/v4 readdir cookies are associated with a verifier,
which is checked by the server on subsequent calls to readdir, and is
only expected to change when the cookies (and hence also the page cache

We therefore do have to store the verifier, but only when the page cache
is empty.

For each device, the nosy driver allocates a pcilynx structure.
A use-after-free might happen in the following scenario:
1. Open nosy device for the first time and call ioctl with command
NOSY_IOC_START, then a new client A will be malloced and added to
doubly linked list.
2. Open nosy device for the second time and call ioctl with command
NOSY_IOC_START, then a new client B will be malloced and added to
doubly linked list.
3. Call ioctl with command NOSY_IOC_START for client A, then client A
will be readded to the doubly linked list. Now the doubly linked
list is messed up.
4. Close the first nosy device and nosy_release will be called. In
nosy_release, client A will be unlinked and freed.
5. Close the second nosy device, and client A will be referenced,
resulting in UAF.
The root cause of this bug is that the element in the doubly linked list
is reentered into the list.
Fix this bug by adding a check before inserting a client. If a client
is already in the linked list, don't insert it.
The following KASAN report reveals it:

* A fix to align the exception vector table correctly, so we don't rely

* A build fix to make NUMA depend on MMU, which triggers some
