Created attachment 1934004 [details] dapl-c99.patch dapl/openib_scm/cm.c calls writev without including <sys/uio.h>, so this results in an implicit function declaration. The upstream web site still exists, but they do not give any indication how to report bugs. The last upstream release is from 2016, so it probably does not matter anyway.
