upgrading kernel with nv_peer_mem-1.0-5 breaks on Ubuntu 14.04.5 #39

Welcome to Ubuntu 14.04.5 LTS (GNU/Linux 4.4.0-116-generic x86_64) ... [76463.688316] nv_peer_mem: disagrees about version of symbol ib_register_peer_memory_client [76463.688326] nv_peer_mem: Unknown symbol ib_register_peer_memory_client (err -22)

this is from nvidia-peer-memory_1.0.5.tar.gz

the problem seems to be that nv_peer_mem/Makefile picks the ofa_kernel symbols from /usr/src/ofa_kernel/default instead of /usr/src/ofa_kernel/$(uname -r). for some reason, default is not

$ uname -r 4.4.0-116-generic $ ls -l //usr/src/ofa_kernel/ total 8 drwxr-xr-x 7 root root 4096 Apr 1 17:35 4.4.0-116-generic drwxr-xr-x 7 root root 4096 Dec 8 18:04 4.4.0-97-generic lrwxrwxrwx 1 root root 16 Dec 8 18:04 default -> 4.4.0-97-generic $ ls -l //usr/src/ofa_kernel/default lrwxrwxrwx 1 root root 16 Dec 8 18:04 //usr/src/ofa_kernel/default -> 4.4.0-97-generic

Hi @drossetti , which version are you using ? This issue has been already addressed in this patch: https://github.com/Mellanox/nv_peer_memory/commit/6b5d3d690a73bff7c07d7eaa7369c08fe40637ec (available since 1.0-6 release).

Thanks, Alaa

@alaahl we need an official release on http://www.mellanox.com/page/products_dyn?product_family=116&mtag=gpudirect. We don't pick random versions from github. thanks
