We are currently working with FreeBSD 4.3 and we found out that kldloading/kldunloading modules working with contigmalloc()/contigfree() like if_xl.ko produces a memory leak.
This is due to the contigfree() function which seems to uncompletely release the memory ressource allocated in vm_page_array. When contigmalloc() steps in vm_page_array, it does not find back the pages previously released by contigfree() The loop vm/vm_page.c is this one: for (i = start; i < cnt.v_page_count; i++) { int pqtype; phys = VM_PAGE_TO_PHYS(&pga[i]); pqtype = pga[i].queue - pga[i].pc; if (pqtype == PQ_FREE It fails on the `pqtype == PQ_FREE' test and the previously allocated (and supposedly released by contigfree) pages can't be reallocated. Anyone has a patch?
