af558a567b Use priv_check(9) instead of suser(9) for checking the privilege to
set real-time priority on a thread.  It looks like this suser(9)
call was introduced after my first pass through replacing superuser
checks with named privilege checks.

b910d10c46 Two changes:
(1) change debounce period from 1s to 250ms.  This appears to be fine and
    speeds things up a little.
(2) In the middle of cbb_pcic_power_disable_socket we write 0 to the EXCA_INTR
    register to put the card into reset.  However, this turns off CSC
    interrupts for TI bridges (and maybe others).  So no further card
    insertion events would be noticed.  To compensate, after we've gone
    through the entire power down sequence, turn on EXCA_INTR_ENABLE so
    that CSC events happen.

#2 should fix the 'dead slot' problem that has been reported after
card ejection (but only 16-bit cards).

cb2d7c85a8 Move vnode-to-file-handle translation from vfs_vptofh to vop_vptofh method.
This way we may support multiple structures in v_data vnode field within
one file system without using black magic.

Vnode-to-file-handle should be VOP in the first place, but was made VFS
operation to keep interface as compatible as possible with SUN's VFS.
BTW. Now Solaris also implements vnode-to-file-handle as VOP operation.

VFS_VPTOFH() was left for API backward compatibility, but is marked for
removal before 8.0-RELEASE.

bc574e3db5 Cleanup and document the implementation of firmware(9) based on
a version that i posted earlier on the -current mailing list,
and subsequent feedback received.

The core of the change is just in sys/firmware.h and kern/subr_firmware.c,
while other files are just adaptation of the clients to the ABI change
(const-ification of some parameters and hiding of internal info,
so this is fully compatible at the binary level).

In detail:
- reduce the amount of information exported to clients in struct firmware,
  and constify the pointer;

- internally, document and simplify the implementation of the various
  functions, and make sure error conditions are dealt with properly.

The diffs are large, but the code is really straightforward now (i hope).

Note also that there is a subtle issue with the implementation of
firmware_register(): currently, as in the previous version, we just
store a reference to the 'imagename' argument, but we should rather
copy it because there is no guarantee that this is a static string.
I realised this while testing this code, but i prefer to fix it in
a later commit -- there is no regression with respect to the past.

Note, too, that the version in RELENG_6 has various bugs including
missing locks around the module release calls, mishandling of modules
loaded by /boot/loader, and so on, so an MFC is absolutely necessary
there.  I was just postponing it until this cleanup to avoid doing
things twice.

5b972eaa75 It turns out that it is easier to not NULL out pccard and cardbus
device pointers.  They don't change as the children device drivers
come and go.  Rather, check to see if the device is attached where we
would have checked ! NULL.  This solves many asymmetries in the code
that likely could lead to crashes when loading/unloading cbb without
one or more of the expected children's driver not present.

97e6505dc8 Adjust the global MSI blacklisting strategy so we don't have to explicitly
blacklist a bunch of old chipsets.  If a system contains a PCI-PCI bridge
that supports PCI-X, assume the chipset supports PCI-X.  If a system
contains a PCI-express root port, assume the chipset supports PCI-express.
If the chipset doesn't support either PCI-X or PCI-express, then blacklist
it by default.  We should now only need to explicitly blacklist PCI-X or
PCI-express chipsets that don't properly handle MSI.

c0d4ce5ca7 Change unp_mtx to supporting recursion, and do not drop the unp_mtx over
sonewconn() in unp_connect().  This avoids a race that occurs due to
v_socket being an uncounted reference, as the lock was being released in
order to call sonewconn(), which otherwise recurses into the UNIX domain
socket code via pru_attach, as well as holding the lock over a sleeping
memory allocation in uipc_attach().  Switch to a non-sleeping memory
allocation during UNIX domain socket attach.

This fix non-ideal in that it requires enabling recursion, but is a much
smaller change than moving to using true references for v_socket.  The
reported panic occurs in unp_connect() following the return of
sonewconn().

e176cc33f5 - Copyright updates (aka 2007)
- ZONE get now also take a type cast so it does the
  cast like mtod does.
- New macro SCTP_LIST_EMPTY, which in bsd is just
  LIST_EMPTY
- Removal of const in some of the static hmac functions
  (not needed)
- Store length changes to allow for new fields in auth
- Auth code updated to current draft (this should be the
  RFC version we think).
- use uint8_t instead of u_char in LOOPBACK address comparison
- Some u_int32_t converted to uint32_t (in crc code)
- A bug was found in the mib counts for ordered/unordered
  count, this was fixed (was referencing a freed mbuf).
- SCTP_ASOCLOG_OF_TSNS added (code will probably disappear
  after my testing completes. It allows us to keep a
  small log on each assoc of the last 40 TSN's in/out and
  stream assignment. It is NOT in options and so is only
  good for private builds.
- Some CMT changes in prep for Jana fixing his problem

  Transfer = CMT).

- Nonce sum was incorrectly being set in when ecn_nonce was

- LOR in listen with implicit bind found and fixed.
- Moved away from using mbuf's for socket options to using

  NetBSD code since both Net and Open used this method. We
  have decided to move away from that and more conform to
  FreeBSD style (which makes more sense).

  conforms to socketapi better
- Found the nasty bug that happens after 9 days of testing.. you
  get the data chunk, deliver it and due to the reference to a ch->
  that every now and then has been deleted (depending on the postion
  in the mbuf) you have an invalid ch->ch.flags.. and thus you don't
  advance the stream sequence number.. so you block the stream
  permanently. The fix is to make local variables of these guys
  and set them up before you have any chance of trimming the
  mbuf.
- style fix in sctp_util.h, not sure how this got bad maybe in
  the last patch? (aka it may not be in the real source).
- Found interesting bug when using the extended snd/rcv info where
  we would get an error on receiving with this. Thats because
  it was NOT padded to the same size as the snd_rcv info. We
  increase (add the pad) so the two structs are the same size
  in sctp_uio.h
- In sctp_usrreq.c one of the most common things we did for
  socket options was to cast the pointer and validate the size.
  This as been macro-ized to help make the code more readable.
- in sctputil.c two things, the socketapi class found a missing
  flag type (the next msg is a notification) and a missing
  scope recovery was also fixed.

boot by MD code to indicated detected alignment preference.  Rather than
cache alignment being encoded in UMA consumers by defining a global
alignment value of (16 - 1) in UMA_ALIGN_CACHE, UMA_ALIGN_CACHE is now
a special value (-1) that causes UMA to look at registered alignment.  If
no preferred alignment has been selected by MD code, a default alignment
of (16 - 1) will be used.

Currently, no hardware platforms specify alignment; architecture
maintainers will need to modify MD startup code to specify an alignment
if desired.  This must occur before initialization of UMA so that all UMA
zones pick up the requested alignment.

4b83088ca6 Fix problem with RTL8201L PHY. From submitter:
Bugfix for the Realtek PHY driver... an RTL8201L standalone PHY
    needs different handling than the integrated ones in terms of
    speed detection.  There was a bogus test based on the parent
    device driver name string controlling which speed register to
    query.  That test began failing when the rl driver was split into
    separate rl and re drivers some time ago.  Apparently nobody ever
    noticed because the buggy code only executes if NWAY negotiation
    failed.  Since we happen to be testing with an ancient dumb hub
    rather than a modern switch, we found it.

    To fix it all, have the attach() routine notice whether we're
    dealing with an integrated PHY or an RTL8201L and store that info
    in a struct accessible to the status() routine that needs to know
    which register to query.

I touched up the fixes because they were relative to RELENG_6 and to
bring a few nits into line with style(9).

a1801d3dbe Simplified PCPU_GET() and PCPU_SET(). We must copy through a temporary
variable to avoid invalid constraints in dead code.  Use an array of
u_char's (inside a struct) instead of a char/short/int/long variable so
that the variable and its accesses can be spelled in the same way in all
cases and code doesn't need to be cloned just to hold the spelling
differences.

Fixed strict-aliasing errors in PCPU_SET() and in the amd64 PCPU_GET().
Cast to (void *) as in rev.1.37 of the i386 version where the errors
were fixed for the i386 PCPU_GET() only.  It would be more correct to
copy to and from the temp. variable using memcpy(), but then an
ifdef tangle would be required to ensure using the builtin memcpy().
We depend on fairly aggressive optimization to put the temp. variable
only in a register despite it being copied using
*(type *)(void *)&anothertype and could depend on this when using
memcpy() too.  This seems to work right even for -O0, but the -O0 case
has not been completely tested.

This change gives identical object code for all object files in LINT
on amd64 (except for one file with a __TIME__ stamp).  For LINT on
i386 it gives unimportant differences in instruction order and padding
in a few object files.  This was only tested for -O.

This change (actually a previous version of it) gives the following
reductions in the number of object files in LINT that fail to compile
with -O2 but without the -fno-strict-aliasing kludge:
- amd64: 29 (down from 211)
- i386: 36 (down from 47)

gcc-3.4.6 actually allows the invalid constraints that result from not
using the temp. variable, at least with -O[1-2], but gcc-3.3.3 crashes
on them and I don't want to depend on compiler bugs.

19777f0802 Introduce accessor functions mac_label_get() and mac_label_set() to replace
LABEL_TO_SLOT() macro used by policy modules to query and set label data

Update policies: in most cases this required only small tweaks to current
wrapper macros.  In two cases, a single wrapper macros had to be split into
separate get and set macros.

Move struct label definition from _label.h to mac_internal.h and remove
_label.h.  With this change, policies may now treat struct label * as
opaque, allowing us to change the layout of struct label without breaking
the policy module ABI.  For example, we could make the maximum number of

2ba513e47f If quotacheck or edquota reset the block or inode grace time for
a user or group, when the kernel first sees this, it will update
the grace time value.  However, it never flags the quota as modified
and the updated value never makes it to the quota data file unless
the user actually makes some other change that would write the
data out.

Fixed to flag the quota as modified if the soft limit has actually
been reached and should be now enforced.

afa51f755a Fix memory leak of devinfo. The leak itself was documented in
PR/108719, but there's a simpler fix: free it after it is used, and
then get rid of the redundant frees this causes.  Other leaks in this
PR not yet fixed.

While I'm here, remove NetBSD/OpenBSD code and some of the portability
#defines that were getting in the way of understanding this code.  The
devinfo bug was harder to spot because one needed to know that
device_set_desc_copy() was used inside of one of them (one that didn't
take an argument!).

Prefer device_printf(sc->sc_dev, "...") to printf("%s:...",
device_get_nameunit(sc->sc_dev)).  This saves almost 300 bytes.

cb84e5a9bd Drop unicast Ethernet frames not destined for the configured address
of a tap(4) instance, if IFF_PROMISC is not set.

In tap(4), we should emulate the effect IFF_PROMISC would have on
hardware, otherwise we risk introducing layer 2 loops if tap(4) is
used with bridges. This means not even bpf(4) gets to see them.

This patch has been tested in a variety of situations. Multicast and
broadcast frames are correctly allowed through. I have observed this
behaviour causing problems with multiple QEMU instances hosted on
the same FreeBSD machine.

The checks in in ether_demux() [if_ethersubr.c, rev 1.222, line 638]
are insufficient to prevent this bug from occurring, as ifp->if_vlantrunk
will always be NULL for the non-vlan case.

fd07387e04 Quoting Alexander:
Formulas described in RFC require high precision of floating point.
  Formulas of integer math implemented in ng_pptpgre give mistake in range
  of +0-7ms on RTT and +0-3ms on deviation. This leads to significant
  underestimation of real packet RTT.

  I have made a very simple patch to reduce mistake to +4-3ms on RTT and
  +2-1ms on deviation. Mistake in RTT is not good, but gets covered by
  deviation. To cover worst possible negative mistake in deviation I have
  added 2ms to it. Also this 2 ms cover the case when measured deviation
  is so small (about zero) that it can interfere with process scheduling
  delays or weather on Mars.

  My tests show decreasing of packet losses on 20ms RTT link from 2.5% to
  0.3% while speed increased un 1/3.

25c4be862e Auto sizing TCP socket buffers.
Normally the socket buffers are static (either derived from global
defaults or set with setsockopt) and do not adapt to real network
conditions. Two things happen: a) your socket buffers are too small
and you can't reach the full potential of the network between both
hosts; b) your socket buffers are too big and you waste a lot of
kernel memory for data just sitting around.

With automatic TCP send and receive socket buffers we can start with a
small buffer and quickly grow it in parallel with the TCP congestion
window to match real network conditions.

FreeBSD has a default 32K send socket buffer. This supports a maximal
transfer rate of only slightly more than 2Mbit/s on a 100ms RTT
trans-continental link. Or at 200ms just above 1Mbit/s. With TCP send
buffer auto scaling and the default values below it supports 20Mbit/s
at 100ms and 10Mbit/s at 200ms. That's an improvement of factor 10, or
1000%. For the receive side it looks slightly better with a default of
64K buffer size.

New sysctls are:
  net.inet.tcp.sendbuf_auto=1 (enabled)
  net.inet.tcp.sendbuf_inc=8192 (8K, step size)
  net.inet.tcp.sendbuf_max=262144 (256K, growth limit)
  net.inet.tcp.recvbuf_auto=1 (enabled)
  net.inet.tcp.recvbuf_inc=16384 (16K, step size)
  net.inet.tcp.recvbuf_max=262144 (256K, growth limit)

347b7a6a1e Change the way the advertized TCP window scaling is computed. Instead of
upper-bounding it to the size of the initial socket buffer lower-bound it
to the smallest MSS we accept.  Ideally we'd use the actual MSS information
here but it is not available yet.

For socket buffer auto sizing to be effective we need room to grow the
receive window.  The window scale shift is determined at connection setup
and can't be changed afterwards.  The previous, original, method effectively
just did a power of two roundup of the socket buffer size at connection
setup severely limiting the headroom for larger socket buffers.

365d5c4ba7 Instead of always hard-coding the socket type for the nfs root mount as
SOCK_DGRAM (i.e. UDP), respect the value configured earlier.  This allows
TCP NFS root mounts using e.g. the boot.nfsroot.options="tcp" tunable.

In this case some of the connection parameters like the retry timer were
previously set appropriately for TCP but inappropriately for the UDP
socket that was actually used, leading to e.g. extremely long recovery
times (O(hours)) after a nfs server reboot.

so we need to build them only on architectures where there's a released
hal; this hack can be eliminated when an ia64 hal build is present

c083ee91fa Revert nd6.c revs. 1.67, 1.68, 1.69, 1.70 in an attempt to unbreak
IPv6 over point-to-point gif(4) tunnels.

These revisions caused a host route to the destination of a
point-to-point gif(4) interface to not get installed when the interface
and destination addresses were assigned.  This caused
"no route to host" errors when trying to send traffic over the
interface.  The first packet arriving inbound over the tunnel,
however, would cause the correct route to get installed, allowing
subsequent outbound traffic to be routed correctly.

gif(4) interfaces with prefix lengths of less than 128 bits
(i.e. no explicit destination address assigned) were not affected
by this bug.

This bug fix is a possible candidate for a 6.2-RELEASE errata note.

0f05ca9b5b - Implement much more intelligent ipi sending. This algorithm tries to
minimize IPIs and rescheduling when scheduling like tasks while keeping
   latency low for important threads.
   1) An idle thread is running.
   2) The current thread is worse than realtime and the new thread is
      better than realtime.  Realtime to realtime doesn't preempt.
   3) The new thread's priority is less than the threshold.

0688eeab06 - Create ng_ppp_bypass() function, that prepares a packet
with bypass header, to send it out to userland.
- Use ng_ppp_bypass() in ng_ppp_proto_recv().
- Use ng_ppp_bypass() in ng_ppp_comp_recv() and in
  ng_ppp_crypt_recv() if compression or encryption is
  disabled, respectively.
- Any LCP packet goes directly to ng_ppp_bypass(), instead
  of passing through PPP stack.
- Any non-LCP packet on disabled link is discarded. This
  is behavior defined in RFC.
