* procmap fumbles with uvm_map_addr structures, which are now in RBTsdlg2016-09-161-16/+31
| | | | | | | | | | | | | | | | | | it also does proper traversal of the tree (ie, it does FOREACH) which in turn uses MIN and NEXT operations to iterate over the whole tree. theyre complicated and need code. so for now this pulls in subr_tree.c from the kernel and builds it as part of procmap. that allows for traversal of the RBT using the same code that the kernel uses. it is a bit ugly though because procmap updates the pointers between items in the tree so they point at local copies instead of kernel addresses. its made worse because RBT code has pointers between rb_entry structs, not between the nodes. im putting this in now to unbreak the tree. it can be polished after coffee/naps.
* Re-introduce vnode-to-filename mappingstefan2016-05-261-4/+70
| | | | | | | | The name cache walking code got adapted to the new name cache layout. Along with the previous commit, procmap is now able to map a vnode to a filename as long as it is in the name cache. "nice stuff" deraadt@
* Must extract uvm_vnode from uvm_object first before reading the vnodestefan2016-05-251-3/+11
| | | | | | | | | Otherwise procmap interprets the uvm_vnode contents as a vnode, yielding bogus values. This should cure the "procmap: invalid address (ffffffffffffffff) == -1 vs. 656 @ ffffffffffffffff" error messages that appear sporadically. ok deraadt@
* Remove am_maxslot from amap.stefan2016-04-161-7/+2
| | | | | | | | | | am_maxslot represents the total number of slots an amap can be extended to. Since we do not extend amaps, this field as well as rounding the number of slots to the next malloc bucket is not useful. This also removes the corresponding output from procmap(1). ok kettenis@

| | | | | | | | | possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

* Reimplement uvm/uvm_map.ariane2011-05-241-70/+107
| | | | | | | | | | | | | vmmap is designed to perform address space randomized allocations, without letting fragmentation of the address space go through the roof. Some highlights: - kernel address space randomization - proper implementation of guardpages - roughly 10% system time reduction during kernel build Tested by alot of people on tech@ and developers. Theo's machines are still happy.

* Namecache revamp.beck2009-08-121-1/+9
| | | | | | | | | | | | | | | This eliminates the large single namecache hash table, and implements the name cache as a global lru of entires, and a redblack tree in each vnode. It makes cache_purge actually purge the namecache entries associated with a vnode when a vnode is recycled (very important for later on actually being able to resize the vnode pool) This commit does #if 0 out a bunch of procmap code that was already broken before this change, but needs to be redone completely. Tested by many, including in thib's nfs test setup. ok oga@,art@,thib@,miod@

| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
* Define a new flag, UVM_FLAG_HOLE, for uvm_map to create a vm_map_entry ofmiod2008-06-091-4/+7
| | | | | | | | | | | | | a new etype, UVM_ET_HOLE, meaning it has no backend. UVM_ET_HOLE entries (which should be created as UVM_PROT_NONE and with UVM_FLAG_NOMERGE and UVM_FLAG_HOLE) are skipped in uvm_unmap_remove(), so that pmap_{k,}remove() is not called on the entry. This is intended to save time, and behave better, on pmaps with MMU holes at process exit time. ok art@, kettenis@ provided feedback as well.
