- If the parent directory of the directory to be removed has its immutable or
append-only flag set, rmdir(2) returns EPERM.

- shuffle memory range following kernel to the beginning of phys_avail
- have the direct area use 256MB pages where possible
- remove dead code from the end of pmap_bootstrap
- have pmap_alloc_contig_pages check all memory ranges in phys_avail before
giving up
- informal benchmarking indicates a ~5% speedup on buildworld
This s part of an import of the PVR-250 driver. Originally it was
calleed pvr250-setchannel, but it seems better to improve this program
to work for any tuner card, so I'm starting with a more generic name.
That shouldn't mislead anybody: currently the program only works with
the (yet to be committed) cxm driver.

an "export" flag indicating that we are trying to NFS export the
filesystem, and the MSDOSFS_LARGEFS flag is set on the filesystem,
then deny the mount update and export request. Otherwise,
let the full mount update proceed normally.
MSDOSFS_LARGES and NFS don't mix because of the way inodes are calculated
for MSDOSFS_LARGEFS.

: Make fdisk initialize the first instead of the last slice by default.
After a change of devd.conf, devd(8) handles NIC attach/detach event
by using /etc/pccard_ether with the interface name as the argument.
This model does not work properly with IPv6 configuration because the
implementation of IPv6 stateless auto-configuration in the FreeBSD
rc.d scripts depends on whether there are any explicit configurations
for interfaces or not. It works this way: if no manual configuration,
it will perform auto-configuration, but otherwise no
auto-configuration will be performed. So, this behavior can only be
determined by all of the interfaces on a system, not a single one.
For this reason, the network6_interface_setup() function called from
the pccard_ether_start() does not work with a single interface name.
And what is worse, this combination of devd.conf and
pccard_ether_start() caused a bad side-effect that when
ipv6_enable=YES, all of interfaces marked as DOWN would be UP
unconditionally (and router solicitation was sent) just after devd(8)
was invoked. This should be fixed in a more sophisticated way.
The symptoms were that outgoing DHCP requests for diskless kernels
had the IP header corrupt. After long investigations, the source of
the problem was found in ether_output() - for SIMPLEX interfaces
and broadcast traffic, a copy of the packet is passed back to the kernel
through if_simloop(). However if_simloop() modifies the mbuf, while
the copy obtained through m_copym() is a readonly one.
The bug has been there forever, but it has been triggered only recently
by a change in sosend_dgram() which passed down mbufs with sufficient
space to prepend the header.
This fix is trivial - use m_dup() instead of m_copy() to create
the copy. As an alternative, we could try and modify if_simloop()
to play safely with readonly mbufs, but i don't think it is worthwhile
because 1) this is a relatively infrequent code path so we do not need
to worry too much about performance, and 2) the cost of doing an
extra m_pullup in if_simloop() is probably the same as doing the
copy of the cluster, anyways.

field to "unsigned long" so that it actually works.
Thanks to Robert Sciuk for sending me a DVD that
demonstrated ISO9660-formatted media with a file >2G.
I've now fixed this both in libarchive and in the cd9660
filesystem.

This allows script compatibility with Linux, whose
"hostname" is the same as BSD "hostname -s".
With this change, "hostname -f" is the same on
both systems.

A kernel with INET6 always has ::1 on lo0, so in the case of
ipv6_enable="NO" the lo0 can have ::1 with no link-local address.
This is a violation of the IPv6 specification. As a workaround for
this situation, fe80::1 is added in rc.d/auto_linklocal when lo0 has
no link-local address. This should not be harmful for IPv4-only users.
config_freebsd.h. archive_platform.h decides which config file
to bring in and uses some of those selectors to define wrapper
macros and other compatibility glue.
timer in xl_txeof()/xl_txeof_90xB(); xl_poll_locked() unconditionally
invokes xl_txeof()/xl_txeof_90xB(), effectively circumventing that
the watchdog ever fires in the DEVICE_POLLING case as its timer is
constantly reloaded.
- Remove the banal and pedantically outdated comment regarding setting
xl_wdog_timer to 0 in xl_txeof().

For filesystems which use vfs_mount_error() to log an error, this
char buffer will be populated with a string error message.
If nmount() fails, in addition to printing out strerror(errno),
print out the "errmsg" populated by vfs_mount_error().
