v2: dereference of most probably already released nlm_host removed in nlmclnt_done() and reclaimer(). These routines are called from locks reclaimer() kernel thread. This thread works in "init_net" network context and currently relays on persence on lockd thread and it's per-net resources. Thus lockd_up() and lockd_down() can't relay on current network context.

It's possible that lockd or another lock manager might still be on the list after we call nfsd4_end_grace. If the laundromat thread runs again at that point, then we could end up calling nfsd4_end_grace more than once. That's not only inefficient, but calling nfsd4_recdir_purge_old more than once could be problematic. Fix this by adding a new global "grace_ended" flag and use that to determine whether we've already called nfsd4_grace_end. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NJ.

Allow a v3 unchecked open of a non-regular file succeed as if it were a lookup; typically a client in such a case will want to fall back on a local open, so succeeding and giving it the filehandle is more useful than failing with nfserr_exist, which makes it appear that nothing at all exists by that name. Similarly for v4, on an open-create, return the same errors we would on an attempt to open a non-regular file, instead of returning nfserr_exist. This fixes a problem found doing a v4 open of a symlink with O_RDONLY|O_CREAT, which resulted in the current client returning EEXIST. Thanks also to Trond for analysis.

Avoid freeing a registered tpg structure if an alloc_workqueue call fails.

Add abort flag and use it to terminate processing when an exchange is timed out or is reset. The abort flag is used in place of the transport_generic_free_cmd function call in the reset and timeout cases, because calling that function in that context would free memory that was in use. The aborted flag allows the lifetime to be managed in a more normal way, while truncating the processing. This change eliminates a source of memory corruption which manifested in a variety of ugly ways.

I have a new optimized x86 "strncpy_from_user()" that will use these same helper functions for all the same reasons the name lookup code uses them. This is preparation for that. This moves them into an architecture-specific header file. It's architecture-specific for two reasons: - some of the functions are likely to want architecture-specific implementations. Even if the current code happens to be "generic" in the sense that it should work on any little-endian machine, it's likely that the "multiply by a big constant and shift" implementation is less than optimal for an architecture that has a guaranteed fast bit count instruction, for example. - I expect that if architectures like sparc want to start playing around with this, we'll need to abstract out a few more details (in particular the actual unaligned accesses). So we're likely to have more architecture-specific stuff if non-x86 architectures start using this. (and if it turns out that non-x86 architectures don't start using this, then having it in an architecture-specific header is still the right thing to do, of course) Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
