The wire protocol is no longer a property that is negotiated between the two peers. It is now expressed with two bits (DP_SEND_WRITE_ACK and DP_SEND_RECEIVE_ACK) in each data packet. Therefore the primary node is free to change the wire protocol at any time without disconnect/reconnect. Signed-off-by:

With this commit the locking for all accesses to IDRs is complete: * Non sleeping read accesses are protected by RCU * sleeping read accesses are protocted by a read lock on drbd_cfg_rwsem * accesses that add anything are protected by a write lock * accesses that remove an object are protoected by a write lock and a call to synchronize_rcu() after it is removed from the IDR and before the object is actually free()ed.

Since have now header 100, that has space for 16 bit volume numbers, the high byte of the length in header 95 is no longer reserved for 8 bit volume numbers. Signed-off-by:

Andreas Gruenbacher authored
The 8 byte header finally becomes too small. With the protocol 100 header we have 16 bit for the volume number, proper 32 bit for the data length, and 32 bit for further extensions in the future. Previous versions of drbd are using version 80 headers for all packets short enough for protocol 80. They support both header versions in worker context, but only version 80 headers in asynchronous context. For backwards compatibility, continue to use version 80 headers for short packets before protocol version 100. From protocol version 100 on, use the same header version for all packets.

Prepare the introduction of the protocol 100 headers. The actual protocol header is removed for the packet declarations. I.e. allow us to use the packets with different headers. Signed-off-by:

Centralize sock->mutex locking and unlocking in [drbd|conn]_prepare_command() and [drbd|conn]_send_comman(). Therefore all *_send_* functions are touched to use these primitives instead of drbd_get_data_sock()/drbd_put_data_sock() and former helper functions. That change makes the *_send_* functions more standardized. Signed-off-by:

Recent commit drbd: get rid of bio_split, allow bios of "arbitrary" size had a reference count leak: it only deactivated the first of several activity log extents for intervals crossing extent boundaries. This commit generalizes on bios spanning multiple activity log extents in drbd_al_begin_io, and adds the necessary loop around lc_put in drbd_al_complete_io as well. Signed-off-by:
