Merge from project branch via main. Uninteresting commits are trimmed.
Refactor of /dev/random device. Main points include:
* Userland seeding is no longer used. This auto-seeds at boot time on PC/Desktop setups; this may need some tweeking and intelligence from those folks setting up embedded boxes, but the work is believed to be minimal.
* An entropy cache is written to /entropy (even during installation) and the kernel uses this at next boot.
* An entropy file written to /boot/entropy can be loaded by loader(8)
* Hardware sources such as rdrand are fed into Yarrow, and are no longer available raw.

Debugging. My attempt at EVENTHANDLER(multiuser) was a failure; use EVENTHANDLER(mountroot) instead.
This means we can't count on /var being present, so something will need to be done about harvesting /var/db/entropy/... .
Some policy now needs to be sorted out, and a pre-sync cache needs to be written, but apart from that we are now ready to go.

Looking pretty good; this mostly works now. New code includes:

* Use EVENTHANDLER to do above just before we go multiuser. Untested.

Contains:
* Refactor the hardware RNG CPU instruction sources to feed into the software mixer. This is unfinished. The actual harvesting needs to be sorted out. Modified by me (see below).
* Remove 'frac' parameter from random_harvest(). This was never used and adds extra code for no good reason.
* Remove device write entropy harvesting. This provided a weak attack vector, was not very good at bootstrapping the device. To follow will be a replacement explicit reseed knob.
* Separate out all the RANDOM_PURE sources into separate harvest entities. This adds some secuity in the case where more than one is present.
* Review all the code and fix anything obviously messy or inconsistent. Address som review concerns while I'm here, like rename the pseudo-rng to 'dummy'.

1) example (partially humorous random_adaptor, that I call "EXAMPLE") * It's not meant to be used in a real system, it's there to show how the basics of how to create interfaces for random_adaptors. Perhaps it should belong in a manual page
2) Move probe.c's functionality in to random_adaptors.c * rename random_ident_hardware() to random_adaptor_choose()
3) Introduce a new way to choose (or select) random_adaptors via tunable "rngs_want" It's a list of comma separated names of adaptors, ordered by preferences. I.e.: rngs_want="yarrow,rdrand"
Such setting would cause yarrow to be preferred to rdrand. If neither of them are available (or registered), then system will default to something reasonable (currently yarrow). If yarrow is not present, then we fall back to the adaptor that's first on the list of registered adaptors.
4) Introduce a way where RNGs can play a role of entropy source. This is mostly useful for HW rngs.
The way I envision this is that every HW RNG will use this functionality by default. Functionality to disable this is also present. I have an example of how to use this in random_adaptor_example.c (see modload event, and init function)
5) fix kern.random.adaptors from kern.random.adaptors: yarrowpanicblock to kern.random.adaptors: yarrow,panic,block
6) add kern.random.active_adaptor to indicate currently selected adaptor: root@freebsd04:~ # sysctl kern.random.active_adaptor kern.random.active_adaptor: yarrow

Bring in some behind-the-scenes development, mainly By Arthur Mesh, the rest by me.
o Namespace cleanup; the Yarrow name is now restricted to where it really applies; this is in anticipation of being augmented or replaced by Fortuna in the future. Fortuna is mentioned, but behind #if logic, and is ignorable for now.
o The harvest queue is pulled out into its own modules.
o Entropy harvesting is emproved, both by being made more conservative, and by separating (a bit!) the sources. Available entropy crumbs are marginally improved.
o Selection of sources is made clearer. With recent revelations, this will receive more work in the weeks and months to come.

Fix a deficiency in the selinfo interface: If a selinfo object is recorded (via selrecord()) and then it is quickly destroyed, with the waiters missing the opportunity to awake, at the next iteration they will find the selinfo object destroyed, causing a PF#.
That happens because the selinfo interface has no way to drain the waiters before to destroy the registered selinfo object. Also this race is quite rare to get in practice, because it would require a selrecord(), a poll request by another thread and a quick destruction of the selrecord()'ed selinfo object.
Fix this by adding the seldrain() routine which should be called before to destroy the selinfo objects (in order to avoid such case), and fix the present cases where it might have already been called. Sometimes, the context is safe enough to prevent this type of race, like it happens in device drivers which installs selinfo objects on poll callbacks. There, the destruction of the selinfo object happens at driver detach time, when all the filedescriptors should be already closed, thus there cannot be a race. For this case, mfi(4) device driver can be set as an example, as it implements a full correct logic for preventing this from happening.

- Expand scope of tun/tap softc locks to cover more softc fields and driver-maintained ifnet fields (such as if_drv_flags). - Use soft locks as the mutex that protects each interface's knote list rather than using the global knote list lock. Also, use the softc for kn_hook instead of the cdev. - Use mtx_sleep() instead of tsleep() when blocking in the read routines. This fixes a lost wakeup race. - Remove D_NEEDGIANT now that the cdevsw routines use the softc lock where locking is needed. - Lock IFQ when calculating the result for FIONREAD in tap(4). tun(4) already did this. - Remove remaining spl calls.

Adapt vfs kqfilter to the shared vnode lock used by zfs write vop. Use vnode interlock to protect the knote fields [1]. The locking assumes that shared vnode lock is held, thus we get exclusive access to knote either by exclusive vnode lock protection, or by shared vnode lock + vnode interlock.
Do not use kl_locked() method to assert either lock ownership or the fact that curthread does not own the lock. For shared locks, ownership is not recorded, e.g. VOP_ISLOCKED can return LK_SHARED for the shared lock not owned by curthread, causing false positives in kqueue subsystem assertions about knlist lock.
Remove kl_locked method from knlist lock vector, and add two separate assertion methods kl_assert_locked and kl_assert_unlocked, that are supposed to use proper asserts. Change knlist_init accordingly.
Add convenience function knlist_init_mtx to reduce number of arguments for typical knlist initialization.

Step 1.5 of importing the network stack virtualization infrastructure from the vimage project, as per plan established at devsummit 08/08: http://wiki.freebsd.org/Image/Notes200808DevSummit
Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator macros, and CURVNET_SET() context setting macros, all currently resolving to NOPs.
Prepare for virtualization of selected SYSCTL objects by introducing a family of SYSCTL_V_*() macros, currently resolving to their global counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT().
Move selected #defines from sys/sys/vimage.h to newly introduced header files specific to virtualized subsystems (sys/net/vnet.h, sys/netinet/vinet.h etc.).

Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere.
This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware.

Remove unit2minor() use from kernel code.
When I changed kern_conf.c three months ago I made device unit numbers equal to (unneeded) device minor numbers. We used to require bitshifting, because there were eight bits in the middle that were reserved for a device major number. Not very long after I turned dev2unit(), minor(), unit2minor() and minor2unit() into macro's. The unit2minor() and minor2unit() macro's were no-ops.
We'd better not remove these four macro's from the kernel, because there is a lot of (external) code that may still depend on them. For now it's harmless to remove all invocations of unit2minor() and minor2unit().

Don't enforce unique device minor number policy anymore.
Except for the case where we use the cloner library (clone_create() and friends), there is no reason to enforce a unique device minor number policy. There are various drivers in the source tree that allocate unr pools and such to provide minor numbers, without using them themselves.
Because we still need to support unique device minor numbers for the cloner library, introduce a new flag called D_NEEDMINOR. All cdevsw's that are used in combination with the cloner library should be marked with this flag to make the cloning work.
This means drivers can now freely use si_drv0 to store their own flags and state, making it effectively the same as si_drv1 and si_drv2. We still keep the minor() and dev2unit() routines around to make drivers happy.
The NTFS code also used the minor number in its hash table. We should not do this anymore. If the si_drv0 field would be changed, it would no longer end up in the same list.

Merge first in a series of TrustedBSD MAC Framework KPI changes from Mac OS X Leopard--rationalize naming for entry points to the following general forms:
mac_<object>_<method/action> mac_<object>_check_<method/action>
The previous naming scheme was inconsistent and mostly reversed from the new scheme. Also, make object types more consistent and remove spaces from object types that contain multiple parts ("posix_sem" -> "posixsem") to make mechanical parsing easier. Introduce a new "netinet" object type for certain IPv4/IPv6-related methods. Also simplify, slightly, some entry point names.
All MAC policy modules will need to be recompiled, and modules not updates as part of this commit will need to be modified to conform to the new KPI.

There is a consensus that ifaddr.ifa_addr should never be NULL, except in places dealing with ifaddr creation or destruction; and in such special places incomplete ifaddrs should never be linked to system-wide data structures. Therefore we can eliminate all the superfluous checks for "ifa->ifa_addr != NULL" and get ready to the system crashing honestly instead of masking possible bugs.

Fix the following bpf(4) race condition which can result in a panic:
(1) bpf peer attaches to interface netif0 (2) Packet is received by netif0 (3) ifp->if_bpf pointer is checked and handed off to bpf (4) bpf peer detaches from netif0 resulting in ifp->if_bpf being initialized to NULL. (5) ifp->if_bpf is dereferenced by bpf machinery (6) Kaboom
This race condition likely explains the various different kernel panics reported around sending SIGINT to tcpdump or dhclient processes. But really this race can result in kernel panics anywhere you have frequent bpf attach and detach operations with high packet per second load.
Summary of changes:
- Remove the bpf interface's "driverp" member - When we attach bpf interfaces, we now set the ifp->if_bpf member to the bpf interface structure. Once this is done, ifp->if_bpf should never be NULL. [1] - Introduce bpf_peers_present function, an inline operation which will do a lockless read bpf peer list associated with the interface. It should be noted that the bpf code will pickup the bpf_interface lock before adding or removing bpf peers. This should serialize the access to the bpf descriptor list, removing the race. - Expose the bpf_if structure in bpf.h so that the bpf_peers_present function can use it. This also removes the struct bpf_if; hack that was there. - Adjust all consumers of the raw if_bpf structure to use bpf_peers_present
Now what happens is:
(1) Packet is received by netif0 (2) Check to see if bpf descriptor list is empty (3) Pickup the bpf interface lock (4) Hand packet off to process
From the attach/detach side:
(1) Pickup the bpf interface lock (2) Add/remove from bpf descriptor list
Now that we are storing the bpf interface structure with the ifnet, there is is no need to walk the bpf interface list to locate the correct bpf interface. We now simply look up the interface, and initialize the pointer. This has a nice side effect of changing a bpf interface attach operation from O(N) (where N is the number of bpf interfaces), to O(1).
[1] From now on, we can no longer check ifp->if_bpf to tell us whether or not we have any bpf peers that might be interested in receiving packets.

Fix some long standing bugs in writing to the BPF device attached to a DLT_NULL interface. In particular:
1) Consistently use type u_int32_t for the header of a DLT_NULL device - it continues to represent the address family as always. 2) In the DLT_NULL case get bpf_movein to store the u_int32_t in a sockaddr rather than in the mbuf, to be consistent with all the DLT types. 3) Consequently fix a bug in bpf_movein/bpfwrite which only permitted packets up to 4 bytes less than the MTU to be written. 4) Fix all DLT_NULL devices to have the code required to allow writing to their bpf devices. 5) Move the code to allow writing to if_lo from if_simloop to looutput, because it only applies to DLT_NULL devices but was being applied to other devices that use if_simloop possibly incorrectly.

Stop embedding struct ifnet at the top of driver softcs. Instead the struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go.
Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

Device megapatch 2/6:
This commit adds a couple of functions for pseudodrivers to use for implementing cloning in a manner we will be able to lock down (shortly).
Basically what happens is that pseudo drivers get a way to ask for "give me the dev_t with this unit number" or alternatively "give me a dev_t with the lowest guaranteed free unit number" (there is unfortunately a lot of non-POLA in the exact numeric value of this number, just live with it for now)
Managing the unit number space this way removes the need to use rman(9) to do so in the drivers this greatly simplifies the code in the drivers because even using rman(9) they still needed to manage their dev_t's anyway.
I have taken the if_tun, if_tap, snp and nmdm drivers through the mill, partly because they (ab)used makedev(), but mostly because together they represent three different problems for device-cloning:
if_tun and snp is the plain case: just give me a device.
if_tap has two kinds of devices, with a flag for device type.
nmdm has paired devices (ala pty) can you can clone either of them.

Make funsetown() take a 'struct sigio **' so that the locking can be done internally.
Ensure that no one can fsetown() to a dying process/pgrp. We need to check the process for P_WEXIT to see if it's exiting. Process groups are already safe because there is no such thing as a pgrp zombie, therefore the proctree lock completely protects the pgrp from having sigio structures associated with it after it runs funsetownlst.
Add sigio lock to witness list under proctree and allproc, but over proc and pgrp.

In order to do this in the most unintrusive manner change pgsigio's sigio * argument into a **, that way we can lock internally to the function.

Change the suser() API to take advantage of td_ucred as well as do a general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

Close a race where we were releasing the unit resource at the start of tunclose() rather than the end, and tunopen() grabbed that unit before tunclose() finished (one process is allocating it while another is freeing it!).
It may be worth hanging some sort of rw mutex around all specinfo calls where d_close and the detach handler get a write lock and all other functions get a read lock. This would guarantee certain levels of ``atomicity'' (is that a word?) that people may expect (I believe Solaris does something like this).

Support /dev/tun cloning. Ansify if_tun.c while I'm there.
Only tun0 -> tun32767 may now be opened as struct ifnet's if_unit is a short.
It's now possible to open /dev/tun and get a handle back for an available tun device (use devname to find out what you got).
The implementation uses rman by popular demand (and against my judgement) to track opened devices and uses the new dev_depends() to ensure that all make_dev()d devices go away before the module is unloaded.

o Allow non-root users to open /dev/tun* (remove suser() in tunopen()) o Change the default device permissions to 0600 root:wheel (were uucp:dialer) o Only let root (suser()) change the MTU

Lock down the network interface queues. The queue mutex must be obtained before adding/removing packets from the queue. Also, the if_obytes and if_omcasts fields should only be manipulated under protection of the mutex.
IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on the queue. An IF_LOCK macro is provided, as well as the old (mutex-less) versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which needs them, but their use is discouraged.
Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF, which takes care of locking/enqueue, and also statistics updating/start if necessary.

Avoid the modules madness I inadvertently introduced by making the cloning infrastructure standard in kern_conf. Modules are now the same with or without devfs support.
If you need to detect if devfs is present, in modules or elsewhere, check the integer variable "devfs_present".
This happily removes an ugly hack from kern/vfs_conf.c.
This forces a rename of the eventhandler and the standard clone helper function.

This change closes some fairly minor security holes associated with F_SETOWN, fixes a few bugs, and removes some limitations that F_SETOWN had on tty devices. For more details, see the description on the PR.
Because this patch increases the size of the proc and pgrp structures, it is necessary to re-install the includes and recompile libkvm, the vinum lkm, fstat, gcore, gdb, ipfilter, ps, top, and w.

Clean up Ethernet drivers: - fill in and use ifp->if_softc - use if_bpf rather than private cookie variables - change bpf interface to take advantage of this - call ether_ifattach() directly from Ethernet drivers - delete kludge in if_attach() that did this indirectly

Pass 3 of the great devsw changes most devsw referenced functions are now static, as they are in the same file as their devsw structure. I've also added DEVFS support for nearly every device in the system, however many of the devices have 'incorrect' names under DEVFS because I couldn't quickly work out the correct naming conventions. (but devfs won't be coming on line for a month or so anyhow so that doesn't matter)
If you "OWN" a device which would normally have an entry in /dev then search for the devfs_add_devsw() entries and munge to make them right.. check out similar devices to see what I might have done in them in you can't see what's going on.. for a laugh compare conf.c conf.h defore and after... :) I have not doen DEVFS entries for any DISKSLICE devices yet as that will be a much more complicated job.. (pass 5 :)
pass 4 will be to make the devsw tables of type (cdevsw * ) rather than (cdevsw) seems to work here.. complaints to the usual places.. :)

If you're going to mechanically replicate something in 50 files it's best to not have a (compiles cleanly) typo in it! (sigh)

OK, that's it.. That's EVERY SINGLE driver that has an entry in conf.c.. my next trick will be to define cdevsw[] and bdevsw[] as empty arrays and remove all those DAMNED defines as well..
Each of these drivers has a SYSINIT linker set entry that comes in very early.. and asks teh driver to add it's own entry to the two devsw[] tables.
some slight reworking of the commits from yesterday (added the SYSINIT stuff and some usually wrong but token DEVFS entries to all these devices.
BTW does anyone know where the 'ata' entries in conf.c actually reside? seems we don't actually have a 'ataopen() etc...
If you want to add a new device in conf.c please make sure I know so I can keep it up to date too..
as before, this is all dependent on #if defined(JREMOD) (and #ifdef DEVFS in parts)

Replaced bogus macros for dummy devswitch entries by functions. These functions went away:
enosys (hasn't been used for some time) enxio enodev enoioctl (was used only once, actually for a vop)
if_tun.c: Continued cleaning up...
conf.h: Probably fixed the type of d_reset_t. It is hard to tell the correct type because there are no non-dummy device reset functions.
Removed last vestige of ambiguous sleep message strings.

Moved prototypes for devswitch functions from conf.c and driver sources to <machine/conf.h>. conf.h was mechanically generated by `grep ^d_ conf.c >conf.h'. This accounts for part of its ugliness. The prototypes should be moved back to the driver sources when the functions are staticalized.

Tunnel driver is nmow capable of installing its own cdevsw[] entry, with a little help from conf.c. While e're at it, actually declare the tunnel entry points to have the correct types. This fixes PR #306.

New user Process PPP based on iij-ppp0.94beta2.
o Supporting SYNC SIO device (But need a device driver) - add "set speed sync" o Fixing bug for Predictor-1 function. o Add new parameter that re-sent interval for set timeout commands. o Improving RTT (Round Trip Time) and reducing processor time. - Previous Timer service was using polling, and now using SIGALRM ;-) - A 0.94beta2 will not work correctly....
-- Follows are additinal feature not including 0.94beta2 o Support Proxy ARP - add "enable/disable proxy" commands o Marging common routine in CHAP/PAP. o Enhancing LCP/IPCP log information. o Support local Authfication connection on port 300x and tty. - You can set up pair of your "hostname -s" and password in ppp.secret. if either ppp.secret file nor your hostname line don't exist, It will notify a message and working as same as previous version.(Backword compatibility) - If you did set up them, It's allow connection but nothing to do except help and passwd command. - add "passwd yourpasswd" commands o Support afilter - keep Alive filter that a packet can send/receiving according to ifilter/ofilter but doesn't count it as preventing idle timer expires. - Same syntax of other filters. o Fixing bugs reported by current user for previous one. Thanks !!
