8a0e3b4be1 In sysctl_destroyv, the newly created dnode structure must have its 
version set to the correct value to prevent later failure of
sysctl_cvt_in.

778eadaf46 Add a printf() to the other case in sysctl_createv() where a node did 
not get attached for what should be an extremely unusual case.

990f278f7a Remove dynamic sysctl node version 0 from the tree. It seemed okay at 
first, but quickly showed its shortcomings.  The version 1 node we're
now using should be good for a while.

275e2ae7f3 First caller to set a description on a node sets it. This allows one 
setup function to set the description, even if the node has been
instantiated elsewhere.  Or not, depending on the other that the setup
functions are called.

44afe14cb6 Unwind the nested designators for fields within structs within structs 
(or unions).  This should really be put back once we're all using gcc3
for everything, since that makes it look a *lot* cleaner.

c6abd47f96 New node version and layout. This should take care of the netbsd32

73c41a46cc Some optimization for sysctl_locate() 2004-03-08 03:31:26 +00:00
atatat
47768f08f2 In sysctl_locate(), use "rnode" like everywhere else, don't call it 
"rv".

In sysctl_destroyv(), deal with deleting alias nodes, and pass a token
size_t to sysctl_destroy().

In sysctl_free(), check that "node" has not reached "rnode", not that
"pnode" has.

In sysctl_realloc(), don't bother setting sysctl_clen...the value is
unchanged.

74dad84b6e Remove two uses of uvm_kernacc(), which wasn't quite getting the job 
done anyway.  On a related change, use kcopy() instead of memcpy() for
kernel-to-kernel copying so that the same service warranty can be
given.

13f8d2ce5f Dynamic sysctl. 
Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al.  Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

5fe02453b5 put back nmaxproc check mistakely changed in rev.1.132 
checking against nprocs is wrong in any case btw - we do allow
maxproc higher than number of current processes, it would just mean
no new process could be started until number of processes would
be lower than the new limit

9e7bb2595e Based on the feedback on wasabisystems.com!bsd-api-discuss (sure wish 
people would read that list in a more timely fashion!), change the new
64-bit memory reporting sysctl nodes to report bytes.  This should not
be a problem, since it's only a week old, and no applications use the
new nodes yet.
