Before mainline commit ea5693cc (v2.6.29-rc1), empty nested netlink attributes were not allowed. Fix that by leaving out nested attributes if they are empty and by allowing the top-level attributes to be missing. Signed-off-by:

We need to remove the flag before checking for valid types. Signed-off-by:

Make it more clear in the flag names which flags are internal to drbd, and which are not. The check for mandatory attributes is the only extension visible at the netlink layer. Attributes with this flag set would look like unknown attributes to some kernel versions. The netlink layer would ignore them and also skip consistency checks on the attribute type and legth. To avoid this, we check for mandatory attributes first, remove the mandatory flag, and then process the attributes normally. Signed-off-by:

Since we need to hold that mutex anyways to make sure the peer gets that change in the right position in the data stream, it makes a lot of sense to use the same mutex to ensure existence of the tfm. Signed-off-by:

* the peer does not speak protocol_version 100 and the user wants to change one of: - wire_protocol - two_primaries - integrity_alg * the user wants to remove the allow_two_primaries flag when there are two primaries Signed-off-by: -

The 32-bit resync_after netlink field takes a device minor number as parameter, which is no longer limited to 255. We cannot statically verify which device numbers are valid, so set the ummer limit to the highest possible signed 32-bit integer. Signed-off-by:

Activity log transaction writes are serialized on a bit lock. If several CPUs race to write an AL transaction, those that did not get the lock the first time may continue as soon as there are no more pending transactions. The do not need to all grab the lock in turn, just to realize that the AL is clean already, and they have nothing to do. This also closes a potential deadlock with drbd_adm_disk_opts. Once it got the AL bit lock, it knows there are no pending transactions, the AL is clean, and it should be safe to wait for all element references to drop to zero. Signed-off-by:

Instead of returning a ret_code outside of the range of enum drbd_ret_code, use NO_ERROR to indicate success. This way, ret_code has the same meaning in all packets. Signed-off-by:

Flags of type NLA_FLAG are either present or absent, but do not have a value by themselves. Use type NLA_U8 for our boolean flags instead, and use the value to determine if the flag should be on or off. On the drbdsetup command line, all those flags have an optional yes/no argument which defaults to yes. Signed-off-by:
