 Description   

I'm testing MOFED 5.1 Beta candidate with lustre master. And I got the following compilation error:
Type 'make' to build Lustre.
+ grep -q 'define[[:space:]]*HAVE_SERVER_SUPPORT' config.h
+ make -j24 -s
Making all in .
/tmp/rpmbuild-lustre--ToFAMKNQ/BUILD/lustre-2.13.54_148_g3fcceea/lnet/klnds/o2iblnd/o2iblnd_cb.c: In function 'kiblnd_reject':
/tmp/rpmbuild-lustre--ToFAMKNQ/BUILD/lustre-2.13.54_148_g3fcceea/lnet/klnds/o2iblnd/o2iblnd_cb.c:2296:9: error: too few arguments to function 'rdma_reject'
rc = rdma_reject(cmid, rej, sizeof(*rej));
The error is related to a change in RDMA_CM API. The change came to MOFED from the upstream kernel:

RDMA/cma: Provide ECE reject reason
IBTA declares "vendor option not supported" reject reason in REJ messages
 if passive side doesn't want to accept proposed ECE options.
Due to the fact that ECE is managed by userspace, there is a need to let
 users to provide such rejected reason.

And the same error is expected with kernel 5.8.

I have a patch for the lustre to support MOFED 5.1 and kernel 5.8. I will push the patch for review soon.
