Hi Sean,
I am currently testing rsockets in connection with ceph.
I am using LD_PRELOAD and the librspreload.so to force
the application (ceph) to use rsockets instead of regular
tcp/ip sockets.
All this works pretty well - until the point where an
established connection is shut down: this seems to not
work and never finishes (unless the application is killed...).
The way ceph uses sockets is in a nonblocking mode.
When reading from a socket, it polls the socket first
with an event mask of POLLIN and POLLRDHUP.
On the return from the poll() I see that
- POLLIN and POLLHUP are set in the returned events
(POLLRDHUP is *not* set)
- errno is 95 (EOPNOTSUPP)
(The POLLHUP makes me believe that in this case the other
end has shutdown the socket already.)
The EOPNOTSUPP confuses ceph quite a bit and prevents it
from shutting down it's side of the socket connection properly.
Question: is it possible that the POLLRDHUP causes the
EOPNOTSUPP to be set by librspreload::poll() or
rpoll()?
Best Regards
Andreas Bluemle
