Introduce a struct icmphdr which contains the type, code, and cksum
fields of an ICMP packet.
Use this to allow ipfw to pullup only these values since it does not use
the rest of the packet and it was failed on ICMP packets because they
were not long enough.
struct icmp should probably be modified to use these at some point, but
that will break a fair bit of code so it can wait for another day.
On the off chance that adding this struct breaks something in ports,
bump __FreeBSD_version.

Fix include directives that were missing the netinet include directory, where
the ipl.h file is found. Also add back in ip_fil.c, which somehow went missing
in action.
Fix problems with building libipf:
ipf_dontuning.c - change the include to look in netinet for ipl.h
ipft_tx.c - make the private use of arrays with tcp flags info in them more
not use names that can be "confusing"
Conditionalize the ipfilter header files on NO_IPFILTER. While normally these
should be harmless, the kdump(1) build does evil things with collecting
system header files, and thus would unconditionally collect and process these.
Apply a torniquet to the problem of the drive unexpectedly disconnecting
during a data phase. Before, we would try to recover the autosense, but
the DMA engine would still be active with interrupted transfer, and we'd
quickly spiral out of control and cause massive data corruption. For now,
just reset the chip and cancel everything. The better solution is to
cancel the DMA operation, but there is no clear way to do that right now.
The data corruption problem is severe enough to warrant this fix in the
interim. Thanks to Kris Kenneway to sacrificing countless filesystems to
this bug.
Add the vm.exec_map_entries tunable and read-only sysctl, which controls
the number of entries in exec_map (maximum number of simultaneous execs
that can be handled by the kernel). The default value of 16 is
insufficient on heavily loaded machines (particularly SMP machines), and
if it is exceeded then executing further processes will generate a SIGABRT.
This is a workaround until a better solution can be implemented.
Correct the if_link_state_change() logic: when the link went down,
if_link_state_change() reported link up, and when the link went up,
if_link_state_change() reported link down. These should be swapped.
Reading the EEPROM to learn the station address doesn't seem to work
on boards with VIA gigE controllers that are embedded in VIA chipsets.
Presumably, they don't have an external EEPROM and store the MAC
address somewhere else. To get around this, force an autoload and
read the station address from the RX filter registers instead.
This has been tested to work on both embedded and standalone
controllers.
* Someone imported a lot of files with the wrong CVS tag, so lots of files need
that fixed in them....
* Keep unnecessary files out of the non-vendor part of this CVS repository.

Only try to allocate and use the SATA resource if they are enabled

result in ATA panic'ing.
Update zconf.h and gzio.c with changes from ZLib 1.2.1 to ZLib 1.2.2.
These are two of the three files that have non-trivial differences from
the vendor branch. minigzip.c is the third, but there were no changes
from ZLib 1.2.1 to ZLib 1.2.2 in that file.
The rest of the files I intend to get reverted back to the vendor
branch (with cooperation of cvsadmin@).
Throw the switch on the new driver generation/loading mechanism. From
here on in, if_ndis.ko will be pre-built as a module, and can be built
into a static kernel (though it's not part of GENERIC). Drivers are
created using the new ndisgen(8) script, which uses ndiscvt(8) under
the covers, along with a few other tools. The result is a driver module
that can be kldloaded into the kernel.
A driver with foo.inf and foo.sys files will be converted into
foo_sys.ko (and foo_sys.o, for those who want/need to make static
kernels). This module contains all of the necessary info from the
.INF file and the driver binary image, converted into an ELF module.
You can kldload this module (or add it to /boot/loader.conf) to have
it loaded automatically. Any required firmware files can be bundled
into the module as well (or converted/loaded separately).
Also, add a workaround for a problem in NdisMSleep(). During system
bootstrap (cold == 1), msleep() always returns 0 without actually
sleeping. The Intel 2200BG driver uses NdisMSleep() to wait for
the NIC's firmware to come to life, and fails to load if NdisMSleep()
doesn't actually delay. As a workaround, if msleep() (and hence
ndis_thsuspend()) returns 0, use a hard DELAY() to sleep instead).
This is not really the right thing to do, but we can't really do much
else. At the very least, this makes the Intel driver happy.
There are probably other drivers that fail in this way during bootstrap.
Unfortunately, the only workaround for those is to avoid pre-loading
them and kldload them once the system is running instead.

- distinguish between the device name (what the user called it on the
command line) and the device path (what we passed to open()). Use
the former in diagnostics.
- when adding or removing partitions, print a single line to stdout for
each partition that was added or removed, indicating its name.
- add an -a option to 'gpt remove' which must be explicitly specified
to remove all partitions.

Without this flag, if the symlink existed already a new symlink would
be created in the source directory. While harmless if the two symlinks
were the same, it nonetheless caused pointless confusion.
The pathological case is that when there is an existing /etc/namedb
symlink, but named_chrootdir in rc.conf pointed to a different
directory, it was the symlink in /var/named that was getting
updated, not the one in /etc. This led to some difficult to diagnose
problems for users.
Overhaul getdate.y. In particular, remove minutes-based logic
(combine with existing seconds-based), treat '-' as punctuation rather
than a negative number indicator (eliminates several special cases),
use a single list of special words instead of several separate lists,
use table-driven abbreviation logic (eliminate duplicate word entries
and special-case abbreviation and plural handling). The result is
shorter, simpler (judging from comments, earlier maintainers didn't
understand the special handling for "negative years"), handles more
cases (e.g., "tu" is now a recognized abbreviation for "tuesday",
"3rd" is now equivalent to "third") and it has 2 fewer shift/reduce
conflicts.
Certain filenames between 245 and 255 characters long would cause an
internal error if pax extended attributes were being generated. Being
< 255 characters, the first-pass path editing (to generate a
ustar-compatible name for the main entry) wouldn't occur, and the
second-pass path editing (to generate a ustar name for the pax
attributes entry) assumed the input was already < 245 chars.
The core problem here was using an abbreviated algorithm for the
second pass that relied on the first pass having already run. The
rewritten code is much simpler: It just uses the full path-shortening
algorithm for building both ustar pathnames. This way, the second
ustar pathname will always be short enough.
Don't use fusufault in casuptr(), as it assumes the current PCB will be

casuptrfault instead.
Add new syscall thr_new to create thread in atomic, it will
inherit signal mask from parent thread, setup TLS and stack, and
user entry address.
Also support POSIX thread's PTHREAD_SCOPE_PROCESS and PTHREAD_SCOPE_SYSTEM,
sysctl is also provided to control the scheduler scope.
Change cpu_set_kse_upcall to more generic style, so we can reuse it
in other codes. Add cpu_set_user_tls, use it to tweak user register
and setup user TLS. I ever wanted to merge it into cpu_set_kse_upcall,
but since cpu_set_kse_upcall is also used by M:N threads which may
not need this feature, so I wrote a separated cpu_set_user_tls.
