Q: Can this case even trigger? Is failing this way any better than one that causes a NULL pointer access? Signed-off-by:

It actually returned the lowest volume number. While doing that renamed a few wrongly named variables. Signed-off-by:

This commit breaks the API again. Move per-volume former syncer options into disk_conf. Move per-connection former syncer options into net_conf. Renamed the remainign sync_conf to res_opts Syncer settings have been changeable at runtime, so we need to prepare for these settings to be runtime-changeable in their new home as well. Introduce new configuration operations, and share the netlink attribute between "attach" (create new disk) and "disk-opts" (change options). Same for "connect" and "net-opts". Some fields cannot be changed at runtime, however. Introduce a new flag GENLA_F_INVARIANT to be able to trigger on that in the generated validation and assignment functions. Signed-off-by:

If drbd_adm_attach failed early, it left the CONFIG_PENDING bit on, blocking any further conn_reconfig_start on that connection. Signed-off-by:

somehow a "goto abort" was introduced with commit drbd: Extracted is_valid_transition() out of sanitize_state() which left drbd_req_state still holding the spin lock. Signed-off-by:

We have resources resp. connections, volumes, and minor numbers. A config request may specifies all three of them. If it turns out that the minor belongs to a different connection, or a different volume number in the same connection, that configuration request is invalid. Signed-off-by:

Follow O_CREAT semantics when creating connection or minor device/volume objects. If we need O_CREAT|O_EXCL semantics some time down the road, we can add NLM_F_EXCL to the netlink message flags. Signed-off-by:

Even if the connection is still established. We should be able to reduce a volume from a replication group, without taking the whole group offline. Signed-off-by:

Get rid of a temporary variable and, funny bitand assignment. Just short circuit, returning false, once we encounter the first still configured volume. FIXME verify call sites for need of rcu_read_lock or stronger. Signed-off-by:

We want to see existing connection objects, even if they do not currently have volumes attached. Change the .dumpit variant of drbd_adm_get_status to iterate not over minor devices, but over connections + volumes. Signed-off-by:

This function was used to broadcast the (leading part of the) bio payload in case we see a data integrity error. It could be received from userland with the drbdsetup events subcommand, to have a peek into the payload that caused the checksum mismatch, and guess from there what may have caused the mismatch, mainly to guess wether it was modification of in-flight data, or data corruption by broken hardware or software bugs. Meanwhile we support bios that are larger than the maximum payload a netlink datagram can carry. And we have means to reliably detect modification of in-flight data by calculating, and comparing, the checksum before and after sendmsg. There is no need to carry this around anymore. Signed-off-by:
