| H A D | imgact_svr4.c | diff 231885 Fri Feb 17 23:47:25 MST 2012 kib Fix misuse of the kernel map in miscellaneous image activators. Vnode-backed mappings cannot be put into the kernel map, since it is a system map. Use exec_map for transient mappings, and remove the mappings with kmem_free_wakeup() to notify the waiters on available map space. Do not map the whole executable into KVA at all to copy it out into usermode. Directly use vn_rdwr() for the case of not page aligned binary. There is one place left where the potentially unbounded amount of data is mapped into exec_map, namely, in the COFF image activator enumeration of the needed shared libraries.
