I brought this question to the debian-devel mailing list: https://lists.debian.org/debian-devel/2017/01/msg00791.html One private feedback was that removing symbols without bumping the soname is a really bad idea (even if they are private symbols). So one option would be to bump the soname once and remove all private symbols in that run. I searched for "ibv_cmd_" in Debian's source code: https://codesearch.debian.net/search?q=ibv_cmd_ It boils down to these source packages: shipped by rdma-core ==================== * librdmacm * libibverbs provided by ibverbs-providers ============================= * libcxgb3 * libmlx5 * libmthca * libnes * libipathverbs * libmlx4 remaining ========= * openmpi openmpi uses ibv_cmd_open_xrcd in config/opal_check_openfabrics.m4: # We have to check functions both exits *and* are declared # since some distro ship broken ibverbs devel headers # IBV_DEVICE_XRC is common to all OFED versions # ibv_create_xrc_rcv_qp was added in OFED 1.3 # ibv_cmd_open_xrcd (aka XRC Domains) was added in OFED 3.12 So I recommend to contact openmpi to let them change their configure check to not check for ibv_cmd_open_xrcd any more. -- Benjamin Drung System Developer Debian & Ubuntu Developer ProfitBricks GmbH Greifswalder Str. 207 D - 10405 Berlin Email: benjamin.drung@xxxxxxxxxxxxxxxx URL: http://www.profitbricks.com Sitz der Gesellschaft: Berlin.
