Scott Mayhew revived an old api that communicates with a userspace daemon to manage some on-disk state that's used to track clients across server reboots. We've been using a usermode_helper upcall for that, but it's tough to run those with the right namespaces, so a daemon is much friendlier to container use cases. Trond fixed nfsd's handling of user credentials in user namespaces. He also contributed patches that allow containers to support different sets of NFS protocol versions. The only remaining container bug I'm aware of is that the NFS reply cache is shared between all containers. If anyone's aware of other gaps in our container support, let me know. The rest of this is miscellaneous bugfixes. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEYtFWavXG9hZotryuJ5vNeUKO4b4FAlzcWNcVHGJmaWVsZHNA ZmllbGRzZXMub3JnAAoJECebzXlCjuG+DUEP/0WD3jKNAHFV3M5YQPAI9fz/iCND Db/A4oWP5qa6JmwmHe61il29QeGqkeFr/NPexgzM3Xw2E39d7RBXBeWyVDuqb0wr 6SCXjXibTsuAHg11nR8Xf0P5Vej3rfGbG6up5lLCIDTEZxVpWoaBJnM8+3bewuCj XbeiDW54oiMbmDjon3MXqVAIF/z7LjorecJ+Yw5+0Jy7KZ6num9Kt8+fi7qkEfFd i5Bp9KWgzlTbJUJV4EX3ZKN3zlGkfOvjoo2kP3PODPVMB34W8jSLKkRSA1tDWYZg 43WhBt5OODDlV6zpxSJXehYKIB4Ae469+RRaIL4F+ORRK+AzR0C/GTuOwJiG+P3J n95DX5WzX74nPOGQJgAvq4JNpZci85jM3jEK1TR2M7KiBDG5Zg+FTsPYVxx5Sgah Akl/pjLtHQPSdBbFGHn5TsXU+gqWNiKsKa9663tjxLb8ldmJun6JoQGkAEF9UJUn dzv0UxyHeHAblhSynY+WsUR+Xep9JDo/p5LyFK4if9Sd62KeA1uF/MFhAqpKZF81 mrgRCqW4sD8aVTBNZI06pZzmcZx4TRr2o+Oj5KAXf6Yk6TJRSGfnQscoMMBsTLkw VK1rBQ/71TpjLHGZZZEx1YJrkVZAMmw2ty4DtK2f9jeKO13bWmUpc6UATzVufHKA C1rUZXJ5YioDbYDy =TUdw -----END PGP SIGNATURE----- Merge tag 'nfsd-5.2' of git://linux-nfs.org/~bfields/linux Pull nfsd updates from Bruce Fields: "This consists mostly of nfsd container work: Scott Mayhew revived an old api that communicates with a userspace daemon to manage some on-disk state that's used to track clients across server reboots.
