Hi, In OpenMPI 2.0, Michael Banck discovered that some of the packages that failed were doing so as openmpi no longer works under fakeroot.
Upstream (Gilles Gouaillaerdet) point out:
from |validate_cred| in
|opal/mca/pmix/pmix112/pmix/src/sec/pmix_native.c|
|getsockopt (peer->sd, SOL_SOCKET, SO_PEERCRED, &ucred, &crlen);|
my understanding is that |fakeroot| tricks the processes into
believing they are ran as |root|,
as such, |orted| expects a connection from |root| (e.g. |ucred.uid|
is |0|)
/* in singleton mode, an |orted| is fork&exec'ed under the hood */
but |fakeroot| cannot trick |getsockopt|, which returns the user
(non zero)
So its a legitimate tightening of credential-checking in pmix. However
it causes problems for us running tests under binary-arch.
What do DDs think should be done about this - move all tests outside
binary-arch?
regards
Alastair
