These files handle the radix tree for the ECMP routes.
The original code from KAME did not take care of address
aliases or multiple ip addresses that have the same
prefix.
This patch provides the back end support for equal-cost multi-path
(ECMP) for both IPv4 and IPv6. Previously, multipath route insertion
is disallowed. For example,
When multipath routes exist, the "route delete" command requires
a specific gateway to be specified or else an error message would
be displayed. For example,
route delete default
would fail and trigger the following error message:
"route: writing to routing socket: No such process"
"delete net default: not in table"
On the other hand,
route delete default 10.2.5.2
would be successful: "delete net default: gateway 10.2.5.2"
One does not have to specify a gateway if there is only a single
route for a particular destination.
I need to perform more testings on address aliases and multiple
interfaces that have the same IP prefixes. This patch as it
stands today is not yet ready for prime time. Therefore, the ECMP
code fragments are fully guarded by the RADIX_MPATH macro.
Include the "options RADIX_MPATH" in the kernel configuration
to enable this feature.
struct lock_instance and struct lock_list_entry don't need to be in the
public namespace for WITNESS as they are only used internally so just
move them in the private namespace for the subsystem (with all related

- Re-introduce WITNESS support for lockmgr. About the old implementation
the only one difference is that lockmgr*() functions now accept
LK_NOWITNESS flag which skips ordering for the instanced calling.
- Remove an unuseful stub in witness_checkorder() (because the above check

non-try operation too.

Make several changes to the way printf handles hex floating point (%a):
1. Previously, printing the number 1.0 could produce 0x1p+0, 0x2p-1,
0x4p-2, or 0x8p-3, depending on what happened to be convenient. This
meant that printing a value as a double and printing the same value
as a long double could produce different (but equivalent) results.
The change is to always make the leading digit a 1, unless the
number is 0. This solves the aforementioned problem and has
several other advantages.
2. Use the FPU to do rounding. This is far simpler and more portable
than manipulating the bits, and it fixes an obsure round-to-even
bug. It also raises the exceptions now required by IEEE 754R.
The drawbacks are that it is usually slightly slower, and it makes
printf less effective as a debugging tool when the FPU is hosed
(e.g., due to a buggy softfloat implementation).
3. On i386, twiddle the rounding precision so that (2) works properly
for long doubles.
4. Make several simplifications that are now possible due to (2).
5. Split __hldtoa() into a separate file.

Don't mess up with CHN_F_TRIGGERED, since it should exclusively

- Use a lockmgr lock rather than a mtx to protect dirhash. This lock
may be held for the duration of the various dirhash operations which
avoids many complex unlock/lock/revalidate sequences.
- Permit shared locks on lookup. To protect the ip->i_dirhash pointer we
use the vnode interlock in the shared case. Callers holding the
exclusive vnode lock can run without fear of concurrent modification to
i_dirhash.
- Hold an exclusive dirhash lock when creating the dirhash structure for
the first time or when re-creating a dirhash structure which has been

- cache dp->i_offset in the local 'i_offset' variable for use in loop
indexes so directory lookup becomes shared lock safe. In the modifying
cases an exclusive lock is held here so the commit routine may
rely on the state of i_offset.
- Similarly handle i_diroff by fetching at the start and setting only once
the operation is complete. Without the exclusive lock these are only
considered hints.
- Assert that an exclusive lock is held when we're preparing for a commit
routine.
- Honor the lock type request from lookup instead of always using exclusive
locking.
Optimize package registration/deregistration. Previously, when looking up the
package name for the origin of a dependency, all entries in /var/db/pkg were
traversed for each dependency of added/removed package. Now, gather all the
origins first, then do the lookup in a single pass over /var/db/pkg.
This should provide a major speedup for packages with hundreds of dependencies.
I've taken a slightly different approach than is used with the ICH8 controllers
in that each controller is not identified individually (eg USB A, USB B, etc).
Instead I've given then same description to each one even though the device ID
differs. This can easily be changed if desired, or ICH8 (and any others using
that approach) can be made to work as this does.

As per restrictions imposed by MD code we can only bind interrupts to
a single cpu presently. Interrupts can be 'unbound' by binding them

Add a new flag, '-C' which enables a special mode that is intended for
catastrophic recovery. Currently, this mode only validates whether a
cylindergroup has good signature data, and prompts the user to decide
whether to clear it as a whole.
This mode is useful when there is data damage on a disk and you are
working on copy of the original disk, as fsck_ffs(8) tends to abnormally
exit in such case, as a last resort to recover data from the disk.
Fix a bug introduced by DEFAULTS feature. When the config file
doesn't exist, we make a directory and then say "oops, that file isn't
there" leaving the directory behind. Add a stat for the config file
so that we detect this before making the directory. This is
semi-lame, but less lame than having this bug.
Fix "top -P" (`&' mistyped as `&&' and a botched logic).
The bug was unnoticed on non-i386 because mp_maxid is
initialized differently, kern.cp_times doesn't print
zeroes for non-existing CPUs, so no "writing outside of
array bounds" happens.
Correct pmap_copy()'s method for extracting the physical address of a
2/4MB page from a PDE. Specifically, change it to use PG_PS_FRAME,
not PG_FRAME, to extract the physical address of a 2/4MB page from a
PDE.
Change the last argument passed to pmap_pv_insert_pde() from a
vm_page_t representing the first 4KB page of a 2/4MB page to the
vm_paddr_t of the 2/4MB page. This avoids an otherwise unnecessary
conversion from a vm_paddr_t to a vm_page_t in pmap_copy().
It seems that RealTek 8129/8139 chip reports invalid length of
received frame under certain conditions. wpaul said the length
0xfff0 is special meaning that indicates hardware is in the
process of copying a packet into host memory. But it seems
there are other cases that hardware is busy or stuck in bad
situation even if the received frame length is not 0xfff0.
To work-around this condition, add a check that verifys that
recevied frame length is in valid range. If received length is out
of range reinitialize hardware to recover from stuck condition.
