gfapi: Fix deadlock while processing upcall

2019-08-02T10:04:58+00:00

As mentioned in bug1733166, there could be potential deadlock
while processing upcalls depending on how each xlator choose
to act on it. The right way of fixing such issues
is to change rpc callback communication process.
- https://github.com/gluster/glusterfs/issues/697

Till then, making changes in gfapi layer to avoid any I/O
processing.

This is backport of below mainline patch

gfapi: fix incorrect initialization of upcall syncop arguments

2019-06-14T04:21:35+00:00

While sending upcall notifications via synctasks, the argument used to
carry relevant data for these tasks is not initialized properly. This patch
is to fix the same.

gfapi: Unblock epoll thread for upcall processing

2019-03-29T07:24:27+00:00

With commit#ad35193,we have made changes to offload
processing upcall notifications to synctask so as not
to block epoll threads. However seems like the issue wasnt
fully addressed.

In "glfs_cbk_upcall_data" -> "synctask_new1" after creating synctask
if there is no callback defined, the thread waits on synctask_join
till the syncfn is finished. So that way even with those changes,
epoll threads are blocked till the upcalls are processed.

Hence the right fix now is to define a callback function for that
synctask "glfs_cbk_upcall_syncop" so as to unblock epoll/notify threads
completely and the upcall processing can happen in parallel by synctask
threads.

gfapi : making glfs_setattr/glfs_fsetattr as public

2019-01-16T06:24:45+00:00

Initially glfs_fsetattr and glfs_setattr, both functions accepted iatt as arguements
but now they accept stat and later in the function the stat is being converted to iatt
so that it can be passed to syncop_fsetattr/syncop_setattr.
