Oooh, very nice! Do you have a list of the dependencies that you actually
needed to install?
Apart from breaking this up into smaller patches, we'll also want to reformat
some of it. Rather than sticking an #if APPLE on top of every spin lock, we
should have utility functions that do this for u

I can put that together. They were boost, gperf, fuse4x, cryptopp. I
think that might have been it.

Hi All,
the docs continuously describe cephx as Kerberos-like, curious why
Kereros isn't used instead.
Developing new security protocols is almost always a bad idea from a
security perspective. I haven't looked deeply into cephx to see how
much is novel (and likely to contain novel bugs) ans how
It turns out to be harmless but the red-black node o_node in the
ceph osd structure is not initialized in create_osd(). Add a
call to rb_init_node() initialize it.

In __unregister_linger_request(), the request is being removed
from the osd client's req_linger list only when the request
has a non-null osd pointer. It should be done whether or not
the request currently has an osd.
This is most likely a non-issue because I believe the request
will always have
Reformat __reset_osd() into three distinct blocks of code
handling the three return cases.

In kick_requests(), we need to register the request before we
unregister the linger request. Otherwise the unregister will
reset the request's osd pointer to NULL.

This series includes two bug fixes that fix confirmed problems, and
two other changes that are technically fix bugs but which probably
won't cause any trouble.

A connection's socket can close for any reason, independent of the

If an osd has no requests and no linger requests, __reset_osd()
will just remove it with a call to __remove_osd(). That drops
a reference to the osd, and therefore the osd may have been free
by the time __reset_osd() returns. That function offers no
indication this may have occurred, and as a res
