Allow up to 300 centi-seconds to be configured for the "ping timeout". There may be setups where heavy congestion, huge buffers, and asymmetric bandwidth limitations may need a "huge" ping-timeout as work-around for "spurious connection loss" problems. Signed-off-by:

Fix warnings of the following nature in the drbd header: In file included from drivers/block/drbd/drbd_bitmap.c:32: drivers/block/drbd/drbd_int.h: In function 'drbd_get_syncer_progress': drivers/block/drbd/drbd_int.h:2234: warning: comparison is always false due to limited range of data where mdev->rs_total (an unsigned long) is being compared to 1ULL << 32, which is always false on a 32-bit machine.

drbdadm already has a --dry-run option, so this option cannot directly be passed through to drbdsetup. Rename the drbdsetup option to resolve this conflict. For backward compatibility, make --dry-run an alias of --tentative. Signed-off-by:

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 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:
