libceph: add ceph_decode_entity_addr Add a function for decoding an entity_addr_t. Once CEPH_FEATURE_MSG_ADDR2 is enabled, the server daemons will start encoding entity_addr_t differently. Add a new helper function that can handle either format. Signed-off-by: Jeff Layton <jlayton@kernel.org> Reviewed-by: "Yan, Zheng" <zyan@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

libceph, ceph: get and handle cluster maps with addrvecs In preparation for msgr2, make the cluster send us maps with addrvecs including both LEGACY and MSGR2 addrs instead of a single LEGACY addr. This means advertising support for SERVER_NAUTILUS and also some older features: SERVER_MIMIC, MONENC and MONNAMES. MONNAMES and MONENC are actually pre-argonaut, we just never updated ceph_monmap_decode() for them. Decoding is unconditional, see commit 23c625ce3065 ("libceph: assume argonaut on the server side"). SERVER_MIMIC doesn't bear any meaning for the kernel client. Since ceph_decode_entity_addrvec() is guarded by encoding version checks (and in msgr2 case it is guarded implicitly by the fact that server is speaking msgr2), we assume MSG_ADDR2 for it.

libceph, ceph: implement msgr2.1 protocol (crc and secure modes) Implement msgr2.1 wire protocol, available since nautilus 14.2.11 and octopus 15.2.5. msgr2.0 wire protocol is not implemented -- it has several security, integrity and robustness issues and therefore considered deprecated.

libceph: allow addrvecs with a single NONE/blank address Normally, an unused OSD id/slot is represented by an empty addrvec. However, it also appears to be possible to generate an osdmap where an unused OSD id/slot has an addrvec with a single blank address of type NONE. Allow such addrvecs and make the end result be exactly the same as for the empty addrvec case -- leave addr intact.

libceph: use TYPE_LEGACY for entity addrs instead of TYPE_NONE Going forward, we'll have different address types so let's use the addr2 TYPE_LEGACY for internal tracking rather than TYPE_NONE. Also, make ceph_pr_addr print the address type value as well.
