2018-04-13libceph: NULL deref on crush_decode() error pathDan Carpenter1-0/+1
[ Upstream commit 293dffaad8d500e1a5336eeb90d544cf40d4fbd8 ] If there is not enough space then ceph_decode_32_safe() does a goto bad. We need to return an error code in that situation. The current code returns ERR_PTR(0) which is NULL. The callers are not expecting that and it results in a NULL dereference.

2017-04-18libceph: don't set weight to IN when OSD is destroyedIlya Dryomov1-1/+0
commit b581a5854eee4b7851dedb0f8c2ceb54fb902c06 upstream. Since ceph.git commit 4e28f9e63644 ("osd/OSDMap: clear osd_info, osd_xinfo on osd deletion"), weight is set to IN when OSD is deleted. This changes the result of applying an incremental for clients, not just OSDs. Because CRUSH computations are obviously affected, pre-4e28f9e63644 servers disagree with post-4e28f9e63644 clients on object placement, resulting in misdirected requests. Mirrors ceph.git commit a6009d1039a55e2c77f431662b3d6cc5a8e8e63f.

2016-08-08libceph: apply new_state before new_up_client on incrementalsIlya Dryomov1-43/+113
[ Upstream commit 930c532869774ebf8af9efe9484c597f896a7d46 ] Currently, osd_weight and osd_state fields are updated in the encoding order. This is wrong, because an incremental map may look like e.g. new_up_client: { osd=6, addr=... } # set osd_state and addr new_state: { osd=6, xorstate=EXISTS } # clear osd_state Suppose osd6's current osd_state is EXISTS (i.e. osd6 is down). After applying new_up_client, osd_state is changed to EXISTS | UP. Carrying on with the new_state update, we flip EXISTS and leave osd6 in a weird "!EXISTS but UP" state. A non-existent OSD is considered down by the mapping code 2087 for (i = 0; i < pg->pg_temp.len; i++) { 2088 if (ceph_osd_is_down(osdmap, pg->pg_temp.osds[i])) { 2089 if (ceph_can_shift_osds(pi)) 2090 continue; 2091 2092 temp->osds[temp->size++] = CRUSH_ITEM_NONE; and so requests get directed to the second OSD in the set instead of the first, resulting in OSD-side errors like: [WRN] : client.4239 192.168.122.21:0/2444980242 misdirected client.4239.1:2827 pg 2.5df899f2 to osd.4 not [1,4,6] in e680/680 and hung rbds on the client: [ 493.566367] rbd: rbd0: write 400000 at 11cc00000 (0) [ 493.566805] rbd: rbd0: result -6 xferred 400000 [ 493.567011] blk_update_request: I/O error, dev rbd0, sector 9330688 The fix is to decouple application from the decoding and: - apply new_weight first - apply new_state before new_up_client - twiddle osd_state flags if marking in - clear out some of the state if osd is destroyed Fixes: http://tracker.ceph.com/issues/14901 Cc: stable@vger.kernel.org # 3.15+: 6dd74e44dc1d: libceph: set 'exists' flag for newly up osd Cc: stable@vger.kernel.org # 3.15+ Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Josh Durgin <jdurgin@redhat.com> Signed-off-by: Sasha Levin <alexander.levin@verizon.com>

osd_primary_affinity array is indexed into incorrectly when checking for non-default primary-affinity values. This nullifies the impact of the rest of the apply_primary_affinity() and results in misdirected requests. if (osds[i] != CRUSH_ITEM_NONE && osdmap->osd_primary_affinity[i] != ^^^ CEPH_OSD_DEFAULT_PRIMARY_AFFINITY) { For a pool with size 2, this always ends up checking osd0 and osd1 primary_affinity values, instead of the values that correspond to the osds in question. E.g., given a [2,3] up set and a [max,max,0,max] primary affinity vector, requests are still sent to osd2, because both osd0 and osd1 happen to have max primary_affinity values and therefore we return from apply_primary_affinity() early on the premise that all osds in the given set have max (default) values.
