Change in ...nfs-ganesha[next]: MDCACHE - Add MDCACHE {} config block
by Daniel Gryniewicz (GerritHub)
Daniel Gryniewicz has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/454929
Change subject: MDCACHE - Add MDCACHE {} config block
......................................................................
MDCACHE - Add MDCACHE {} config block
Add a config block name MDCACHE that is a copy of CACHEINODE. Both can
be configured, but MDCACHE will override CACHEINODE. This allows us to
deprecate CACHEINODE.

lseek gets bad offset from nfs client with ganesha/gluster which supports SEEK
by Kinglong Mee
The latest ganesha/gluster supports seek according to,
https://tools.ietf.org/html/draft-ietf-nfsv4-minorversion2-41#section-15.11
From the given sa_offset, find the next data_content4 of type sa_what
in the file. If the server can not find a corresponding sa_what,
then the status will still be NFS4_OK, but sr_eof would be TRUE. If
the server can find the sa_what, then the sr_offset is the start of
that content. If the sa_offset is beyond the end of the file, then
SEEK MUST return NFS4ERR_NXIO.
For a file's filemap as,
Part 1: HOLE 0x0000000000000000 ---> 0x0000000000600000
Part 2: DATA 0x0000000000600000 ---> 0x0000000000700000
Part 3: HOLE 0x0000000000700000 ---> 0x0000000001000000
SEEK(0x700000, SEEK_DATA) gets result (sr_eof:1, sr_offset:0x70000) from ganesha/gluster;
SEEK(0x700000, SEEK_HOLE) gets result (sr_eof:0, sr_offset:0x70000) from ganesha/gluster.
If an application depends the lseek result for data searching, it may enter infinite loop.
while (1) {
next_pos = lseek(fd, cur_pos, seek_type);
if (seek_type == SEEK_DATA) {
seek_type = SEEK_HOLE;
} else {
seek_type = SEEK_DATA;
}
if (next_pos == -1) {
return ;
cur_pos = next_pos;
}
The lseek syscall always gets 0x70000 from nfs client for those two cases,
but, if underlying filesystem is ext4/f2fs, or the nfs server is knfsd,
the lseek(0x700000, SEEK_DATA) gets ENXIO.
I wanna to know,
should I fix the ganesha/gluster as knfsd return ENXIO for the first case?
or should I fix the nfs client to return ENXIO for the first case?
thanks,
Kinglong Mee

...
Notice rq_u1 == 0. nfs_rpc_process_request is calling free_args which is calling nfs_dupreq_rele. There is a comment at the beginning of nfs_dupreq_rele:
* We assert req->rq_u1 now points to the corresponding duplicate request
* cache entry (dv).
But this assumption doesn't seem to be true, and eventually this will be dereferenced leading to a crash. We're trying to reproduce the problem with NIV_FULL_DEBUG.
Has anyone seen this problem before, or know what would cause rq_u1 to be 0? Should there be a check for NULL in nfs_dupreq_rele in addition to DUPREQ_NOCACHE?

Change in ...nfs-ganesha[next]: Fix accessing object handle after freeing its last state
by Malahal (GerritHub)
Malahal has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/478659 )
Change subject: Fix accessing object handle after freeing its last state
......................................................................
Fix accessing object handle after freeing its last state
nfs4_op_close() calls state_del_locked() while deleting the state found.
This could be the last state for the object handle and the last refcount as
well leading to access after free in state_del_locked() while accessing the
object handle after deleting state.
Fix this by using state_del() instead.
Also, nfs4_op_close() uses data->current_obj instead of the corresponding
state's object handle. These could be different especially when an object
handle gets re-allocated as an earlier object handle gets deleted from the
hash table due to state_wipe_file call on it.

Get and set ACLs API for FSAL_CEPH
For ceph_get_acl, first get extended attr from CephFS by

xattr_2_posix_acl,finally convert the POSIX ACLs to FSAL ACL by
posix_acl_2_fsal_acl.
For ceph_set_acl, it is a reverse procedure.
