sunrpc: make debugfs file creation failure non-fatal

2015-03-31T18:15:08Z

We currently have a problem that SELinux policy is being enforced when creating debugfs files. If a debugfs file is created as a side effect of doing some syscall, then that creation can fail if the SELinux policy for that process prevents it. This seems wrong. We don't do that for files under /proc, for instance, so Bruce has proposed a patch to fix that. While discussing that patch however, Greg K.H. stated: "No kernel code should care / fail if a debugfs function fails, so please fix up the sunrpc code first." This patch converts all of the sunrpc debugfs setup code to be void return functins, and the callers to not look for errors from those functions. This should allow rpc_clnt and rpc_xprt creation to work, even if the kernel fails to create debugfs files for some reason. Symptoms were failing krb5 mounts on systems using gss-proxy and selinux.

Pull nfsd updates from Bruce Fields: "The main change is the pNFS block server support from Christoph, which allows an NFS client connected to shared disk to do block IO to the shared disk in place of NFS reads and writes. This also requires xfs patches, which should arrive soon through the xfs tree, barring unexpected problems. Support for other filesystems is also possible if there's interest. Thanks also to Chuck Lever for continuing work to get NFS/RDMA into shape" * 'for-3.20' of git://linux-nfs.org/~bfields/linux: (32 commits) nfsd: default NFSv4.2 to on nfsd: pNFS block layout driver exportfs: add methods for block layout exports nfsd: add trace events nfsd: update documentation for pNFS support nfsd: implement pNFS layout recalls nfsd: implement pNFS operations nfsd: make find_any_file available outside nfs4state.c nfsd: make find/get/put file available outside nfs4state.c nfsd: make lookup/alloc/unhash_stid available outside nfs4state.c nfsd: add fh_fsid_match helper nfsd: move nfsd_fh_match to nfsfh.h fs: add FL_LAYOUT lease type fs: track fl_owner for leases nfs: add LAYOUT_TYPE_MAX enum value nfsd: factor out a helper to decode nfstime4 values sunrpc/lockd: fix references to the BKL nfsd: fix year-2038 nfs4 state problem svcrdma: Handle additional inline content svcrdma: Move read list XDR round-up logic ...

SUNRPC: Add helpers to prevent socket create from racing

2015-02-09T02:47:29Z

The socket lock is currently held by the task that is requesting the connection be established. While that is efficient in the case where the connection happens quickly, it is racy in the case where it doesn't. What we really want is for the connect helper to be able to block access to the socket while it is being set up. This patch does so by arranging to transfer the socket lock from the task that is requesting the connect attempt, and then releasing that lock once everything is done. This scheme also gives us automatic protection against collisions with the RPC close code, so we can kill the cancel_delayed_work_sync() call in xs_close(). Signed-off-by: Trond Myklebust
