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.

NetBSD version is a feature-to-feature re-implementation of GNU
gzip using the freely-redistributable zlib and this version is
expected to be mostly bug-to-bug compatible with the GNU
implementation.
- Because this is a piece of mature code and we want to make
changes so it is added directly rather than importing to
src/contrib.
- Connect newly added code to src/usr.bin/ and rescue/rescue
build.
- Disconnect the GNU gzip code from build for now, they will
be eventually removed completely.
- Provide two new src.conf(5) knobs, WITHOUT_BZIP2_SUPPORT and
WITHOUT_BZIP2.

apparently be confused by short TCP segments that have been manually
padded to the minimum ethernet frame size. The driver does short frame
padding in software as a workaround for a bug in the 8169 PCI devices
that causes short IP fragments to be corrupted due to an apparent
conflict between the hardware autopadding and hardware IP checksumming.
To fix this, we avoid software padding for short TCP segments, since
the hardware seems to autopad and checksum these correctly (even the
older 8169 NICs get these right). Short UDP packets appear to be
handled correctly in all cases. This should work around the IP header
checksum bug in the 8169 while not tripping the TCP checksum bug in
the 8111B/8168B and 8101E.

- User changes first key (setkey) from keyfile to passphrase and doesn't

This result in device beeing unaccesable after detach.
One can recover from this situation by guessing number of iterations
generated, storing it in metadata and trying to attach device.

maxpages on a zone is woken up, with the rest never being woken up as
a result of the ZFLAG_FULL flag being cleared. Wakeup all such blocked
procsses instead. This change introduces a thundering herd, but since
this should be relatively infrequent, optimizing this (by introducing
a count of blocked processes, for example) may be premature.

This only works if there is no significant drift and all processors are
running at the same frequency. Fortunately, schedgraph traces on MP
machines tend to cover less than a second so drift shouldn't be an issue.
- KTRFile::synchstamp() iterates once over the whole list to determine the
lowest tsc value and syncs adjusts all other values to match. We assume
that the first tick recorded on all cpus happened at the same instant to
start with.
- KTRFile::monostamp() iterates again over the whole file and checks for
a cpu agnostic monotonically increasing clock. If the time ever goes
backwards the cpu responsible is adjusted further to fit. This will
make the possible incorrect delta between cpus as small as the shortest
time between two events. This time can be fairly large due to sched_lock
essentially protecting all events.
- KTRFile::checkstamp() now returns an adjusted timestamp.
- StateEvent::draw() detects states that occur out of order in time and
draws them as 0 pixels after printing a warning.
