kernel: use gettime(9)/getuptime(9) in lieu of time_second(9)/time_uptime(9)

time_second(9) and time_uptime(9) are widely used in the kernel to
quickly get the system UTC or system uptime as a time_t. However,
time_t is 64-bit everywhere, so it is not generally safe to use them
on 32-bit platforms: you have a split-read problem if your hardware
cannot perform atomic 64-bit reads.

This patch replaces time_second(9) with gettime(9), a safer successor
interface, throughout the kernel. Similarly, time_uptime(9) is replaced
with getuptime(9).

There is a performance cost on 32-bit platforms in exchange for
eliminating the split-read problem: instead of two register reads you
now have a lockless read loop to pull the values from the timehands.
This is really not *too* bad in the grand scheme of things, but
compared to what we were doing before it is several times slower.

There is no performance cost on 64-bit (__LP64__) platforms.

With input from visa@, dlg@, and tedu@.

Several bugs squashed by visa@.

ok kettenis@

Convert infinite sleeps to tsleep_nsec(9).

ok bluhm@, cheloha@

Fix vn_open to require an op of 0, and 0 or KERNELPATH only as flags.

sweep tree to correct NDIINT op and flags ahead of time. document
the requirement. This allows KERNELPATH to be used to bypass
unveil for crash dumps with nosuidcoredump=2 or 3

ok visa@ deraadt@ florian@

Drop unnecessary `p' parameter from vget(9).

OK mpi@

Remove proc from the parameters of vn_lock(). The parameter is
unnecessary because curproc always does the locking.

OK mpi@

Clean up the parameters of VOP_LOCK() and VOP_UNLOCK(). It is always
curproc that does the locking or unlocking, so the proc parameter
is pointless and can be dropped.

OK mpi@, deraadt@

Remove almost unused `flags' argument of suser().

The account flag `ASU' will no longer be set but that makes suser()
mpsafe since it no longer mess with a per-process field.

no change in compiler assembly output.

First step towards more sane time handling in the kernel -- this changes
things such that code that only need a second-resolution uptime or wall

this from separate time_t globals time_second and time_uptime.

Changes to allow two partitions to share a quota file

Don't use #define QUOTA - use stub file instead

Pass over the quota code in ufs/. Make code paths clearer. Clean up some names.
Move all code that manipulates quotas directly into ufs_quota.c

Use vfs_mount_foreach_vnode to traverse list of vnodes in mountpoint.

branches: 1.7.4;
zap the newhashinit hack.
Add an extra flag to hashinit telling if it should wait in malloc.
update all calls to hashinit.

Updates for VFS Lite 2 + soft update.

back out vfs lite2 till after 2.2

VFS Lite2 Changes

Integrate new ext2fs, reverting ufs support for the old one.

From NetBSD: update to 960217 sources

branches: 1.1.1;
Initial revision

Remove almost unused `flags' argument of suser().

The account flag `ASU' will no longer be set but that makes suser()
mpsafe since it no longer mess with a per-process field.

No objection from millert@, ok tedu@, bluhm@

Don't pull in <sys/file.h> just to get fcntl.h

ok deraadt@ krw@

Remove the unused flags argument from VOP_UNLOCK().

torture tested on amd64, i386 and macppc

"the change looks right" deraadt

Change a bunch of (<blah> *)0 to NULL.

ok beck@ deraadt@

rename desiredvnodes to initialvnodes. less of a lie. ok beck deraadt

use siphash for key lookups in all the filesystem hashes.

ok deraadt@ tedu@

Add dumping of struct dqblk done by quotactl(2)

ok millert@

Calling quotactl(QCMD(Q_QUOTAON)) twice with the same filesystem,
type, and path shouldn't leak vnode or ucred references.

ok millert@

Eliminates struct pcred by moving the real and saved ugids into
struct ucred; struct process then directly links to the ucred

Based on a discussion at c2k10 or so before noting that FreeBSD and
NetBSD did this too.

ok matthew@

replace old bcopy/bzero with standard functions. ok kettenis

final removal of daddr64_t. daddr_t has been 64 bit for a long enough
test period; i think 3 years ago the last bugs fell out.
ok otto beck others

Make the ffs code 64-bit disk block number clean. Based on a diff
from Pedro Martelleto. Two things remain: the on-disk quota
structures are still 32-bit and statfs does not do 64-bit numbers
yet. ok deraadt@

Last of the really easy bzero() -> M_ZERO. Use 'p = malloc(sizeof(*p) ...'
where obvious.

Increase dq_cnt in struct dquot from 16 to 32bits. OK deraadt@

Remove the v_interlock simplelock from the vnode structure.
Zap all calls to simple_lock/unlock() on it (those calls are
#defined away though). Remove the LK_INTERLOCK from the calls
to vn_lock() and cleanup the filesystems wich implement VOP_LOCK().
(by remvoing the v_interlock from there calls to lockmgr()).

ok pedro@, art@, tedu@

Consistently spell FALLTHROUGH to appease lint.
ok kettenis@ cloder@ tom@ henning@

rename vfs_busy() flags VB_UMIGNORE/VB_UMWAIT to VB_NOWAIT/VB_WAIT

requested by and ok pedro

move vfs_busy() to rwlocks and properly hide the locking api from vfs

ok tedu, pedro

remove the simplelock argument from vfs_busy() which is currently not
used and will never be used this way in VFS

requested by and ok pedro, ok krw, biorn

Use the DIP macros to uniformly access fields from UFS1 and UFS2 dinodes.
No functional change, okay tedu@.

No need for vfs_busy() and vfs_unbusy() to take a process pointer
anymore. Testing by jolan@, thanks.

Use ANSI function declarations and deregister, no binary change.
Diff from Rui Reis <rui@rui.cx>, thanks.

Extended Attributes was a piece to get to ACLs, however ACLs have not
been worked on, so EA is pointless. Also the code is not enabled
in GENERIC so it is not being tested or maintained.

Use list and queue macros where applicable to make the code easier to read;
no change in compiler assembly output.

First step towards more sane time handling in the kernel -- this changes
things such that code that only need a second-resolution uptime or wall
time, and used to get that from time.tv_secs or mono_time.tv_secs now get
this from separate time_t globals time_second and time_uptime.

ok art@ niklas@ nordin@

some pieces of ufs2. help testing otto sturm

change arguments to suser. suser now takes the process, and a flags
argument. old cred only calls user suser_ucred. this will allow future
work to more flexibly implement the idea of a root process. looks like
something i saw in freebsd, but a little different.
use of suser_ucred vs suser in file system code should be looked at again,
for the moment semantics remain unchanged.
review and input from art@ testing and further review miod@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

First round of __P removal in sys

Credentials now freed on re-use of dq structure.

Extended Attribute support from FreeBSD/TrustedBSD ok art@, deraadt@

Don't rely on vp for anything in dqsync as it can be null
