IMHO proper fixing of incremental build is needed urgently.
In r266650, we made libatf-c and libatf-c++ private libraries so that no
components outside of the source tree could unintendedly depend on them.
This change does the same for the "atf-sh library" by moving the atf-sh
interpreter from its public location in /usr/bin/ to the private location
in /usr/libexec/. Our build system will ensure that our own test programs
use the right binary, but users won't be able to depend on atf-sh by
"mistake".
Committing this now to ride the UPDATING notice added with r267172 today.
The libatf-* major version numbers in FreeBSD were one version ahead of
upstream because, when atf was first imported into FreeBSD, the upstream
numbers were not respected. This is just confusing and bound to cause
problems down the road.
Fix this by taking advantage of the fact that libatf-* are now private
and that atf is not yet built by default. However, and unfortunately, a
clean build is needed for tests to continue working once "make
delete-old-libs" has been run; hence the note in UPDATING.

Formerly, a command like find dir1/dir2 -delete would delete everything
under dir1/dir2 but not dir1/dir2 itself.
When -L is not specified and "." can be opened, the fts(3) code underlying
find(1) is careful to avoid following symlinks or being dropped in different
locations by moving the directory fts is currently traversing. If a
problematic concurrent modification is detected, fts will not enter the
directory or abort. Files found in the search are returned via the current
working directory and a pathname not containing a slash.
For paranoia, find(1) verifies this when -delete is used. However, it is too
paranoid about the root of the traversal. It is already assumed that the
initial pathname does not refer to directories or symlinks that might be
replaced by untrusted users; otherwise, the whole traversal would be unsafe.
Therefore, it is not necessary to do the check for fts_level ==
FTS_ROOTLEVEL.
Deleting the pathnames given as arguments can be prevented without error
messages using -mindepth 1 or by changing directory and passing "." as
argument to find. This works in the old as well as the new version of find.

Before this change path matching had the following features:
- for device nodes the patterns were matched against full path
- in the above case '/' in a path could be matched by a wildcard
- for directories and links only the last component was matched
So, for example, a pattern like 're*' could match the following entries:
- re0 device
- responder/u0 device
- zvol/recpool directory
Although it was possible to work around this behavior (once it was spotted
and understood), it was very confusing and contrary to documentation.
Now we always match a full path for all types of devfs entries (devices,
directories, links) and a '/' has to be matched explicitly.
This behavior follows the shell globbing rules.

- Add an OSD (Object Specific Data) pointer to struct tcpcb to allow Khelp

support in mii(4):
- Merge generic flow control advertisement (which can be enabled by
passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from
NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
IFM_FLOW isn't implemented as a global option via the "don't care
mask" but instead as a media specific option this. This has the
following advantages:
o allows flow control advertisement with autonegotiation to be
turned on and off via ifconfig(8) with the default typically
being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)
o allows to deal with PHY drivers where flow control advertisement
with manual selection doesn't work or at least isn't implemented,
like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
by setting MIIF_NOMANPAUSE
o the available combinations of media options are readily available
from the `ifconfig -m` output
- Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
- Change IFM_ETH_MASTER from being implemented as a global option via
the "don't care mask" to a media specific one as it actually is only
applicable to IFM_1000_T to date.
- Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
actually configure manually selected slave mode (like we also do in
the PHY specific implementations).
- Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it
is understood by ifconfig(8).
o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
e1000phy(4) and ip1000phy(4) to use the generic flow control support
instead of home-grown solutions via IFM_FLAGs. This includes changing
these PHY drivers and smcphy(4) to no longer unconditionally advertise
support for flow control but only if the selected media has IFM_FLOW
set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the
contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
just BCM5701. Apparently this was a misinterpretation of a workaround
in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
this doesn't mean we can't set these as well on other PHYs for manual
media selection.
o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so
IFM_1000_T master mode support now is generally available with all PHY
drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's
not applicable there.

Control Algorithms for FreeBSD" FreeBSD Foundation funded project. More details
about the project are available at: http://caia.swin.edu.au/freebsd/5cc/
- Add a KPI and supporting infrastructure to allow modular congestion control
algorithms to be used in the net stack. Algorithms can maintain per-connection
state if required, and connections maintain their own algorithm pointer, which
allows different connections to concurrently use different algorithms. The
TCP_CONGESTION socket option can be used with getsockopt()/setsockopt() to
programmatically query or change the congestion control algorithm respectively
from within an application at runtime.
- Integrate the framework with the TCP stack in as least intrusive a manner as
possible. Care was also taken to develop the framework in a way that should
allow integration with other congestion aware transport protocols (e.g. SCTP)
in the future. The hope is that we will one day be able to share a single set
of congestion control algorithm modules between all congestion aware transport
protocols.
- Introduce a new congestion recovery (TF_CONGRECOVERY) state into the TCP stack
and use it to decouple the meaning of recovery from a congestion event and
recovery from packet loss (TF_FASTRECOVERY) a la RFC2581. ECN and delay based
congestion control protocols don't generally need to recover from packet loss
and need a different way to note a congestion recovery episode within the
stack.
- Remove the net.inet.tcp.newreno sysctl, which simplifies some portions of code
and ensures the stack always uses the appropriate mechanisms for recovering
from packet loss during a congestion recovery episode.
- Extract the NewReno congestion control algorithm from the TCP stack and
massage it into module form. NewReno is always built into the kernel and will
remain the default algorithm for the forseeable future. Implementations of
additional different algorithms will become available in the near future.
- Bump __FreeBSD_version to 900025 and note in UPDATING that rebuilding code
that relies on the size of "struct tcpcb" is required.

The $ip6addrctl_policy is a variable to choose a pre-defined address
selection policy set by ip6addrctl(8).
The keyword "ipv4_prefer" sets IPv4-preferred one described in Section 10.3,
the keyword "ipv6_prefer" sets IPv6-preferred one in Section 2.1 in RFC 3484,
respectively. When "AUTO" is specified, it attempts to read
/etc/ip6addrctl.conf first. If it is found, it reads and installs it as
a policy table. If not, either of the two pre-defined policy tables is
chosen automatically according to $ipv6_activate_all_interfaces.
When $ipv6_activate_all_interfaces=NO, interfaces which have no corresponding
$ifconfig_IF_ipv6 is marked as IFDISABLED for security reason.
The default values are ip6addrctl_policy=AUTO and
ipv6_activate_all_interfaces=NO.

M UPDATING
Deliverables: Small and clean code (1,4 KSLOC vs GNU's 8,5 KSLOC),
lower memory usage than GNU grep, GNU compatibility,
BSD license.
TODO: Performance is somewhat behind GNU grep but it is only
significant for bigger searches. The reason is complex, the
most important factor is that GNU grep uses lots of
optimizations to improve the speed of the regex library.
First, we need a modern regex library (practically by adopting
TRE), add support for GNU-style non-standard regexes and then
reevalute the performance issues and look for bottlenecks. In
the meantime, for those, who need better performance, it is
possible to build GNU grep by setting WITH_GNU_GREP.

architecture from page queue lock to a hashed array of page locks
(based on a patch by Jeff Roberson), I've implemented page lock
support in the MI code and have only moved vm_page's hold_count
out from under page queue mutex to page lock. This changes
pmap_extract_and_hold on all pmaps.

are some problems with static executables), make.conf (would also
affect ports which do not use GNU make and do not override the
compile targets) or in the kernel config (via "makeoptions
WITH_CTF=yes").
Additional (related) changes:
- propagate WITH_CTF to module builds
- do not add -g to the linker flags, it's a noop there anyway
(at least according to the man page of ld)
- do not add -g to CFLAGS unconditionally
we need to have a look if it is really needed (IMO not) or if there
is a way to add it only when WITH_CTF is used
Note: ctfconvert / ctfmerge lines will not appear in the build output,
to protect the innocent (those which do not build with WITH_CTF would
see the shell-test and may think WITH_CTF is used).

for upcoming 64-bit PowerPC and MIPS support. This renames the COMPAT_IA32
option to COMPAT_FREEBSD32, removes some IA32-specific code from MI parts
of the kernel and enhances the freebsd32 compatibility code to support
big-endian platforms.

This utility allows users to convert their wtmp databases to the new
format. It makes no sense for users to keep their wtmp log files if they
are unable to view them.
It basically copies ut_line into ut_id as well. This makes it possible
for last(1) and ac(8) to match login records with their corresponding
logout record.
While the name is pretentious, a good explanation of its targets is
reported in this 17 months old presentation e-mail:

In order to implement it, the sq_type in sleepqueues is mandatory and not
only compiled along with INVARIANTS option. Additively, a new sleepqueue
function, sleepq_type() is added, returning the type of the sleepqueue
linked to a wchan.
Three new sysctls are added in order to configure the thread:
debug.deadlkres.slptime_threshold
debug.deadlkres.blktime_threshold
debug.deadlkres.sleepfreq
rappresenting the thresholds for sleep and block time that will lead to
a deadlock matching (when exceeded), while the sleepfreq rappresents the
number of seconds between 2 consecutive thread runnings.
In order to enable the deadlock resolver thread recompile your kernel
with the option DEADLKRES.
