/*
* General overview:
* full generic netlink message:
* |nlmsghdr|genlmsghdr|<payload>
*
* payload:
* |optional fixed size family header|<sequence of netlink attributes>
*
* sequence of netlink attributes:
* I chose to have all "top level" attributes NLA_NESTED,
* corresponding to some real struct.
* So we have a sequence of |tla, len|<nested nla sequence>
*
* nested nla sequence:
* may be empty, or contain a sequence of netlink attributes
* representing the struct fields.
*
* The tag number of any field (regardless of containing struct)
* will be available as T_ ## field_name,
* so you cannot have the same field name in two differnt structs.
*
* The tag numbers themselves are per struct, though,
* so should always begin at 1 (not 0, that is the special "NLA_UNSPEC" type,
* which we won't use here).
* The tag numbers are used as index in the respective nla_policy array.
*
* GENL_struct(tag_name, tag_number, struct name, struct fields) - struct and policy
* genl_magic_struct.h
* generates the struct declaration,
* generates an entry in the tla enum,
* genl_magic_func.h
* generates an entry in the static tla policy
* with .type = NLA_NESTED
* generates the static <struct_name>_nl_policy definition,
* and static conversion functions

* and provides a send helper
*
* GENL_notification(op_name, op_num, mcast_group, tla list)
* These are notifications to userspace.
*
* genl_magic_struct.h
* generates an entry in the genl_ops enum,
* genl_magic_func.h
* does nothing
*
* mcast group: the name of the mcast group this notification should be
* expected on
* tla list: the list of expected top level attributes,
* for documentation and sanity checking.
*
* GENL_op(op_name, op_num, flags and handler, tla list) - "genl operations"
* These are requests from userspace.
*
* _op and _notification share the same "number space",
* op_nr will be assigned to "genlmsghdr->cmd"
*
* genl_magic_struct.h
* generates an entry in the genl_ops enum,
* genl_magic_func.h
* generates an entry in the static genl_ops array,

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.

drbd: when receiving P_TRIM, zero-out partial unaligned chunks We can avoid spurious data divergence caused by partially-ignored discards on certain backends with discard_zeroes_data=0, if we translate partial unaligned discard requests into explicit zero-out. The relevant use case is LVM/DM thin. If on different nodes, DRBD is backed by devices with differing discard characteristics, discards may lead to data divergence (old data or garbage left over on one backend, zeroes due to unmapped areas on the other backend). Online verify would now potentially report tons of spurious differences. While probably harmless for most use cases (fstrim on a file system), DRBD cannot have that, it would violate our promise to upper layers that our data instances on the nodes are identical. To be correct and play safe (make sure data is identical on both copies), we would have to disable discard support, if our local backend (on a Primary) does not support "discard_zeroes_data=true". We'd also have to translate discards to explicit zero-out on the receiving (typically: Secondary) side, unless the receiving side supports "discard_zeroes_data=true". Which both would allocate those blocks, instead of unmapping them, in contrast with expectations. LVM/DM thin does set discard_zeroes_data=0, because it silently ignores discards to partial chunks. We can work around this by checking the alignment first. For unaligned (wrt. alignment and granularity) or too small discards, we zero-out the initial (and/or) trailing unaligned partial chunks, but discard all the aligned full chunks. At least for LVM/DM thin, the result is effectively "discard_zeroes_data=1". Arguably it should behave this way internally, by default, and we'll try to make that happen. But our workaround is still valid for already deployed setups, and for other devices that may behave this way. Setting discard-zeroes-if-aligned=yes will allow DRBD to use discards, and to announce discard_zeroes_data=true, even on backends that announce discard_zeroes_data=false. Setting discard-zeroes-if-aligned=no will cause DRBD to always fall-back to zero-out on the receiving side, and to not even announce discard capabilities on the Primary, if the respective backend announces discard_zeroes_data=false. We used to ignore the discard_zeroes_data setting completely. To not break established and expected behaviour, and suddenly cause fstrim on thin-provisioned LVs to run out-of-space, instead of freeing up space, the default value is "yes".

drbd: implement csums-after-crash-only Checksum based resync trades CPU cycles for network bandwidth, in situations where we expect much of the to-be-resynced blocks to be actually identical on both sides already. In a "network hickup" scenario, it won't help: all to-be-resynced blocks will typically be different. The use case is for the resync of *potentially* different blocks after crash recovery -- the crash recovery had marked larger areas (those covered by the activity log) as need-to-be-resynced, just in case. Most of those blocks will be identical. This option makes it possible to configure checksum based resync, but only actually use it for the first resync after primary crash.

drbd: New net configuration option socket-check-timeout In setups involving a DRBD-proxy and connections that experience a lot of buffer-bloat it might be necessary to set ping-timeout to an unusual high value. By default DRBD uses the same value to wait if a newly established TCP-connection is stable. Since the DRBD-proxy is usually located in the same data center such a long wait time may hinder DRBD's connect process. In such setups socket-check-timeout should be set to at least to the round trip time between DRBD and DRBD-proxy. I.e. in most cases to 1.

drbd: Allow online change of al-stripes and al-stripe-size Allow to change the AL layout with an resize operation. For that the reisze command gets two new fields: al_stripes and al_stripe_size. In order to make the operation crash save: 1) Lock out all IO and MD-IO 2) Write the super block with MDF_PRIMARY_IND clear 3) write the bitmap to the new location (all zeros, since we allow only while connected) 4) Initialize the new AL-area 5) Write the super block with the restored MDF_PRIMARY_IND. 6) Unfreeze all IO Since the AL-layout has no influence on the protocol, this operation needs to be beforemed on both sides of a resource (if intended).

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.

While for now we keep the status information in /proc/drbd available, this commit allows the user base to gracefully migrate their monitoring infrastructure to the new status reporting interface. In drbd9 no status information is exposed through /proc/drbd.
