2017-06-19port the RBT code to userland by making it part of libc.David Gwynne
src/lib/libc/gen/tree.c is a copy of src/sys/kern/subr_tree.c, but with annotations for symbol visibility. changes to one should be reflected in the other. the malloc debug code that uses RB code is ported to RBT. because libc provides the RBT code, procmap doesn't have to reach into the kernel and build subr_tree.c itself now. mild enthusiasm from many ok guenther@
2016-09-25Make a move towards ending 4 decades of kernel snooping.Theo de Raadt
Add sysctl kern.allowkmem (default 0) which controls the ability to open /dev/mem or /dev/kmem at securelevel > 0. Over 15 years we converted 99% of utilities in the tree to operate on sysctl-nodes (either by themselves or via code hiding in the guts of -lkvm). pstat -d and -v & procmap are affected and continued use of them will require kern.allowkmem=1 in /etc/sysctl.conf. acpidump (and it's buddy sendbug) are affected, but we'll work out a solution soon. There will be some impact in ports. ok kettenis guenther
2016-09-16procmap fumbles with uvm_map_addr structures, which are now in RBTsDavid Gwynne
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.
2016-05-26Re-introduce vnode-to-filename mappingStefan Kempf
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@
2016-05-25Must extract uvm_vnode from uvm_object first before reading the vnodeStefan Kempf
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@
2016-04-16Remove am_maxslot from amap.Stefan Kempf
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@
2015-03-13remove the first comma from constructs like ", and," and ", or,": you can useJason McIntyre
"and" and "or" to join sentence clauses, and you can use commas, but both hinders reading;
2015-01-19Also print the fspace member of map entries when PRINT_VM_MAP_ENTRY isMark Kettenis
requested. ok deraadt@
2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
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)
2014-11-16Replace a plethora of historical protection options with justTheo de Raadt
PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h. PROT_MASK is introduced as the one true way of extracting those bits. Remove UVM_ADV_* wrapper, using the standard names. ok doug guenther kettenis

2013-03-23rework the main loop so we can drop kmem privs a little later,Ted Unangst

2012-03-09Userspace counterpart of new vmmap.Ariane van der Steldt
Allows memory walks to function.
2011-09-03make -column lists pretty again;Jason McIntyre
specifically, rewrite them to permit some markup in the column headers, and use "Ta" instead of literal tabs; mandoc does not currently match groff 100%, but a mandoc fix may be some time off, and we've gone enough releases with poorly formatting column lists. in some cases i have rewritten the lists as -tag, where -column made little sense.
2011-06-06Userland counterpart of the vmmap backout; cranks major version of libkvm.Ariane van der Steldt
2011-05-24Reimplement uvm/uvm_map.Ariane van der Steldt
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.
2011-04-23BRKSIZ is the right constant now, so I don't get lots of teeny tiny heapsTed Unangst

new name cache information gathering code.
2009-08-12Namecache revamp.Bob Beck
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@

2008-06-26First pass at removing clauses 3 and 4 from NetBSD licenses.Ray Lai
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@
2008-06-09Define a new flag, UVM_FLAG_HOLE, for uvm_map to create a vm_map_entry ofMiod Vallat
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.
