attribute namespace and DAC protection on file:
- Attribute names beginning with '$' are in the system namespace
- The attribute name "$" is reserved
- System namespace attributes may only be read/set by suser()
or by kernel (cred == NULL)
- Other attribute names are in the application namespace
- The attribute name "" is reserved
- Application namespace attributes are protected in the manner
of the target file permission
o Kernel changes
- Add ufs_extattr_valid_attrname() to check whether the requested
attribute "set" or "enable" is appropriate (i.e., non-reserved)
- Modify ufs_extattr_credcheck() to accept target file vnode, not
to take inode uid
- Modify ufs_extattr_credcheck() to check namespace, then enforce
either kernel/suser for system namespace, or vaccess() for
application namespace
o EA backing file format changes
- Remove permission fields from extended attribute backing file
header
- Bump extended attribute backing file header version to 3
o Update extattrctl.c and extattrctl.8
- Remove now deprecated -r and -w arguments to initattr, as
permissions are now implicit
- (unrelated) fix error reporting and unlinking during failed
initattr to remove duplicate/inaccurate error messages, and to
only unlink if the failure wasn't in the backing file open()

cloning infrastructure standard in kern_conf. Modules are now
the same with or without devfs support.
If you need to detect if devfs is present, in modules or elsewhere,
check the integer variable "devfs_present".
This happily removes an ugly hack from kern/vfs_conf.c.
This forces a rename of the eventhandler and the standard clone
helper function.
Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include
like <sys/queue.h>
Remove all #includes of opt_devfs.h they no longer matter.

setproctitle() is prototyped in unistd.h as opposed to stdlib.h

machines. The patch uses an existing global variable in place of the
newbus accessor to get at use_bwx.
This is a quick fix to get miatas booting again; somebody
with more newbus skills than I can muster will have to correct it.
Matt Jacob's description of the problem from the -alpha list:
The IVAR accessor stuff for pcib is incompletely specified for CIA. There's
only one accessor defined, and that's to get the BUS instance number.
<..>
The device methods that try and get at the use_bwx get overriden because
there's only one ivar for CIA's pcib, and that's for hose #, and it's always
zero.
the link and activity LED control bits in CSR15 in order for the
controller to drive the LEDs correctly. This was largely done for the
ZNYX multiport cards, but should also work with the DEC DE500-BA
and other non-MII cards.
enable bit hasn't been set in the command register, set the bit and
honour the register. It seems that quite a few lazy BIOS writers
aren't bothering to do this, which upsets the existing code and causes
us to miss out on properly-configured devices.
pcib instance is initialized because accesses to PCI_Config region can
occur during ACPI initialization.
Note that this is a short term solution, more consideration will be
required in order to integrate ACPI into the newbus probe sequence.

fields between host and network byte order. The details:
o icmp_error() now does not add IP header length. This fixes the problem
when icmp_error() is called from ip_forward(). In this case the ip_len
of the original IP datagram returned with ICMP error was wrong.
o icmp_error() expects all three fields, ip_len, ip_id and ip_off in host
byte order, so DTRT and convert these fields back to network byte order
before sending a message. This fixes the problem described in PR 16240
and PR 20877 (ip_id field was returned in host byte order).
o ip_ttl decrement operation in ip_forward() was moved down to make sure
that it does not corrupt the copy of original IP datagram passed later
to icmp_error().
o A copy of original IP datagram in ip_forward() was made a read-write,
independent copy. This fixes the problem I first reported to Garrett
Wollman and Bill Fenner and later put in audit trail of PR 16240:
ip_output() (not always) converts fields of original datagram to network
byte order, but because copy (mcopy) and its original (m) most likely
share the same mbuf cluster, ip_output()'s manipulations on original
also corrupted the copy.
o ip_output() now expects all three fields, ip_len, ip_off and (what is
significant) ip_id in host byte order. It was a headache for years that
ip_id was handled differently. The only compatibility issue here is the
raw IP socket interface with IP_HDRINCL socket option set and a non-zero
ip_id field, but ip.4 manual page was unclear on whether in this case
ip_id field should be in host or network byte order.
not alias `ip_src' unless it comes from the host an original
datagram that triggered this error message was destined for.

pcib_set_bus() cannot be used on the new child because it is
meant to be used on the *pci* device (it looks at the parent internally)
not the pcib being added. Bite the bullet and use ivars for the bus
number to avoid any doubts about whether the softc is consistant between
probe and attach. This should not break the Alpha code.

This fixes a panic later in the boot process on a UP1000. From
inspection, it looks like this fixes a similar problem in the tsunami code.
