Implement a Samba VFS plugin for glusterfs based on gluster's gfapi.
This is a "bottom" vfs plugin (not something to be stacked on top of
another module), and translates (most) calls into closest actions
on gfapi.
Anand before we push this in samba I would like to have an answer about
access control.
I have tried to find out exactly how access control is handled but the
code is complex.
However what I found so far is not encouraging.
I see things like:
#define GF_MAX_AUX_GROUPS 200
and then in syncop_create_frame() that value is used to cap the max
number of auxiliary groups.
In Linux the max number of auxiliary groups is 65536 and we have seen
easily 2k auxiliary groups attached to a user in Windows domains.
Currently it is artificially limited to a number. I will work on making
this dynamic. However this will be a completely internal change to
glusterfs with no changes in either API or vfs_glusterfs. Thanks for the
feedback.
I have started working on this. Can we interpret this as a limitation of
glusterfs, rather than an issue with the VFS module?
Let me know if there are any blockers for the merge.
Thanks,
Avati
