| | | | | | | | | | | | | | | | | | | | It is not just a pointer to crush_work, it is the whole structure. That is not a problem since it only contains a pointer.

| | | | | | | | | | | | | | | | | | | | If there is no crush_choose_arg_map for a given pool, a NULL pointer is passed to preserve existing crush_do_rule() behavior.

| * crush: implement weight and id overrides for straw2Ilya Dryomov2017-07-072-19/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bucket_straw2_choose needs to use weights that may be different from weight_items. For instance to compensate for an uneven distribution caused by a low number of values. Or to fix the probability biais introduced by conditional probabilities (see http://tracker.ceph.com/issues/15653 for more information). We introduce a weight_set for each straw2 bucket to set the desired weight for a given item at a given position. The weight of a given item when picking the first replica (first position) may be different from the weight the second replica (second position). For instance the weight matrix for a given bucket containing items 3, 7 and 13 could be as follows: position 0 position 1 item 3 0x10000 0x100000 item 7 0x40000 0x10000 item 13 0x40000 0x10000 When crush_do_rule picks the first of two replicas (position 0), item 7, 3 are four times more likely to be choosen by bucket_straw2_choose than item 13. When choosing the second replica (position 1), item 3 is ten times more likely to be choosen than item 7, 13. By default the weight_set of each bucket exactly matches the content of item_weights for each position to ensure backward compatibility. bucket_straw2_choose compares items by using their id. The same ids are also used to index buckets and they must be unique. For each item in a bucket an array of ids can be provided for placement purposes and they are used instead of the ids. If no replacement ids are provided, the legacy behavior is preserved. Reflects ceph.git commit 19537a450fd5c5a0bb8b7830947507a76db2ceca. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
| * libceph: apply_upmap()Ilya Dryomov2017-07-071-2/+95
| | | | | | | | | | | | | | | | | | | | | | Previously, pg_to_raw_osds() didn't filter for existent OSDs because raw_to_up_osds() would filter for "up" ("up" is predicated on "exists") and raw_to_up_osds() was called directly after pg_to_raw_osds(). Now, with apply_upmap() call in there, nonexistent OSDs in pg_to_raw_osds() output can affect apply_upmap(). Introduce remove_nonexistent_osds() to deal with that.

| * libceph: pg_upmap[_items] infrastructureIlya Dryomov2017-07-072-3/+155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | pg_temp and pg_upmap encodings are the same (PG -> array of osds), except for the incremental remove: it's an empty mapping in new_pg_temp for pg_temp and a separate old_pg_upmap set for pg_upmap. (This isn't to allow for empty pg_upmap mappings -- apparently, pg_temp just wasn't looked at as an example for pg_upmap encoding.) Reuse __decode_pg_temp() for decoding pg_upmap and new_pg_upmap. __decode_pg_temp() stores into pg_temp union member, but since pg_upmap union member is identical, reading through pg_upmap later is OK.

| * libceph: ceph_decode_skip_* helpersIlya Dryomov2017-07-071-22/+3
| | | | | | | | | | | | | | | | | | | | | | Some of these won't be as efficient as they could be (e.g. ceph_decode_skip_set(... 32 ...) could advance by len * sizeof(u32) once instead of advancing by sizeof(u32) len times), but that's fine and not worth a bunch of extra macro code. Replace skip_name_map() with ceph_decode_skip_map as an example. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

| | | | | | | | | | | | | | | | | | Otherwise we may miss events like PG splits, pool deletions, etc when we get multiple incremental maps at once.

| * libceph: delete from need_resend_linger before check_linger_pool_dne()Ilya Dryomov2017-07-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When processing a map update consisting of multiple incrementals, we may end up running check_linger_pool_dne() on a lingering request that was previously added to need_resend_linger list. If it is concluded that the target pool doesn't exist, the request is killed off while still on need_resend_linger list, which leads to a crash on a NULL lreq->osd in kick_requests(): libceph: linger_id 18446462598732840961 pool does not exist BUG: unable to handle kernel NULL pointer dereference at 0000000000000010 IP: ceph_osdc_handle_map+0x4ae/0x870 Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

* | bonding: avoid NETDEV_CHANGEMTU event when unregistering slaveWANG Cong2017-07-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Hongjun/Nicolas summarized in their original patch: " When a device changes from one netns to another, it's first unregistered, then the netns reference is updated and the dev is registered in the new netns. Thus, when a slave moves to another netns, it is first unregistered. This triggers a NETDEV_UNREGISTER event which is caught by the bonding driver. The driver calls bond_release(), which calls dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in the old netns). " This is a very special case, because the device is being unregistered no one should still care about the NETDEV_CHANGEMTU event triggered at this point, we can avoid broadcasting this event on this path, and avoid touching inetdev_event()/addrconf_notify() path. It requires to export __dev_set_mtu() to bonding driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two problems with calling sock_create_kern() from rds_tcp_accept_one() 1. it sets up a new_sock->sk that is wasteful, because this ->sk is going to get replaced by inet_accept() in the subsequent ->accept() 2.

This is because we forgot to implement the get_net_proto for sctp and dccp, so we won't invoke the nf_ct_unregister_sysctl to free the ctl_table when do netns cleanup. Also note, we will fail to register the sysctl for dccp/sctp either due to the lack of get_net_proto.
