* libceph: add nocephx_sign_messages optionIlya Dryomov2015-11-021-1/+2
| | | | | | | | | | | | | | | Support for message signing was merged into 3.19, along with nocephx_require_signatures option. But, all that option does is allow the kernel client to talk to clusters that don't support MSG_AUTH feature bit. That's pretty useless, given that it's been supported since bobtail. Meanwhile, if one disables message signing on the server side with "cephx sign messages = false", it becomes impossible to use the kernel client since it expects messages to be signed if MSG_AUTH was negotiated. Add nocephx_sign_messages option to support this use case. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

* libceph: msg signing callouts don't need con argumentIlya Dryomov2015-11-021-3/+2
| | | | | | | | | | We can use msg->con instead - at the point we sign an outgoing message or check the signature on the incoming one, msg->con is always set. We wouldn't know how to sign a message without an associated session (i.e. msg->con == NULL) and being able to sign a message using an explicitly provided authorizer is of no use.

* libceph: advertise support for keepalive2Ilya Dryomov2015-09-171-0/+1
| | | | | | | | | We are the client, but advertise keepalive2 anyway - for consistency, if nothing else. In the future the server might want to know whether its clients support keepalive2. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Yan, Zheng <zyan@redhat.com>
* libceph: don't access invalid memory in keepalive2 pathIlya Dryomov2015-09-171-1/+3
| | | | | | | | | | | | | | | | This struct ceph_timespec ceph_ts; ... con_out_kvec_add(con, sizeof(ceph_ts), &ceph_ts); wraps ceph_ts into a kvec and adds it to con->out_kvec array, yet ceph_ts becomes invalid on return from prepare_write_keepalive(). As a result, we send out bogus keepalive2 stamps. Fix this by encoding into a ceph_timespec member, similar to how acks are read and written.

* libceph: enable ceph in a non-default network namespaceIlya Dryomov2015-07-091-0/+3
| | | | | | | | | | | | | | Grab a reference on a network namespace of the 'rbd map' (in case of rbd) or 'mount' (in case of ceph) process and use that to open sockets instead of always using init_net and bailing if network namespace is anything but init_net. Be careful to not share struct ceph_client instances between different namespaces and don't add any code in the !CONFIG_NET_NS case. This is based on a patch from Hong Zhiguo <zhiguohong@tencent.com>. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Sage Weil <sage@redhat.com>

* libceph: store timeouts in jiffies, verify user inputIlya Dryomov2015-06-251-6/+11
| | | | | | | | | | | | | | | | | | | | | | There are currently three libceph-level timeouts that the user can specify on mount: mount_timeout, osd_idle_ttl and osdkeepalive. All of these are in seconds and no checking is done on user input: negative values are accepted, we multiply them all by HZ which may or may not overflow, arbitrarily large jiffies then get added together, etc. There is also a bug in the way mount_timeout=0 is handled. It's supposed to mean "infinite timeout", but that's not how wait.h APIs treat it and so __ceph_open_session() for example will busy loop without much chance of being interrupted if none of ceph-mons are there. Fix all this by verifying user input, storing timeouts capped by msecs_to_jiffies() in jiffies and using the new ceph_timeout_jiffies() helper for all user-specified waits to handle infinite timeouts correctly.

* ceph: fix file lock interruptionYan, Zheng2014-12-171-2/+5
| | | | | | | | | | | | | When a lock operation is interrupted, current code sends a unlock request to MDS to undo the lock operation. This method does not work as expected because the unlock request can drop locks that have already been acquired. The fix is use the newly introduced CEPH_LOCK_FCNTL_INTR/CEPH_LOCK_FLOCK_INTR requests to interrupt blocked file lock request. These requests do not drop locks that have alread been acquired, they only interrupt blocked file lock request. Signed-off-by: Yan, Zheng <zyan@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for mon_get_version requests to libceph. This reuses much of the ceph_mon_generic_request infrastructure, with one exception. Older OSDs don't set mon_get_version reply hdr->tid even if the original request had a non-zero tid, which makes it impossible to lookup ceph_mon_generic_request contexts by tid in get_generic_reply() for such replies. As a workaround, we allocate a reply message on the reply path. This can probably interfere with revoke, but I don't see a better way.
