Instead, use proper macro defined in Makefile per ${MACHINE_ARCH}.
__${MACHINE_ARCH}__ doesn't represent an architecture of tool's target
but an architecture of binaries being compiled, so required features
are not prolery enabled or unintentionally enabled on certain host
and target combinations during src/tools build.
- Use %.40g rather than %g when printing sectors and MB for existing
partition size/offset.
Changes [1.93802e+06c, 1953525105s, 953870M]:
to: [1938021c, 1953525105s, 953869.6875M]:
It just fakes MBR partition map which contains 1MB FAT16B partition
and ~1GB OpenBSD partition, and we can always create necessary
MBR partitions for OpenFirmware by the fdisk(8) command itself.
Drastically reduces the amount of time spent rewriting parity after an
unclean shutdown by keeping better track of which regions might have had
outstanding writes. Enabled by default; can be disabled on a per-set
basis, or tuned, with the new raidctl(8) commands.
Discussed on tech-kern@ to a general air of approval; exhortations to
commit from mrg@, christos@, and others.
Thanks to Google for their sponsorship, oster@ for mentoring the
project, assorted developers for trying very hard to break it, and
probably more I'm forgetting.
- Separate the suser part of the bsd44 secmodel into its own secmodel
and directory, pending even more cleanups. For revision history
purposes, the original location of the files was
src/sys/secmodel/bsd44/secmodel_bsd44_suser.c
src/sys/secmodel/bsd44/suser.h
- Add a man-page for secmodel_suser(9) and update the one for
secmodel_bsd44(9).
- Add a "secmodel" module class and use it. Userland program and
documentation updated.
- Manage secmodel count (nsecmodels) through the module framework.
This eliminates the need for secmodel_{,de}register() calls in
secmodel code.
- Prepare for secmodel modularization by adding relevant module bits.
The secmodels don't allow auto unload. The bsd44 secmodel depends
on the suser and securelevel secmodels. The overlay secmodel depends
on the bsd44 secmodel. As the module class is only cosmetic, and to
prevent ambiguity, the bsd44 and overlay secmodels are prefixed with
"secmodel_".
- Adapt the overlay secmodel to recent changes (mainly vnode scope).
- Stop using link-sets for the sysctl node(s) creation.
- Keep sysctl variables under nodes of their relevant secmodels. In
other words, don't create duplicates for the suser/securelevel
secmodels under the bsd44 secmodel, as the latter is merely used
for "grouping".
- For the suser and securelevel secmodels, "advertise presence" in
relevant sysctl nodes (sysctl.security.models.{suser,securelevel}).
- Get rid of the LKM preprocessor stuff.
- As secmodels are now modules, there's no need for an explicit call
to secmodel_start(); it's handled by the module framework. That
said, the module framework was adjusted to properly load secmodels
early during system startup.
- Adapt rump to changes: Instead of using empty stubs for securelevel,
simply use the suser secmodel. Also replace secmodel_start() with a
call to secmodel_suser_start().
- 5.99.20.
Testing was done on i386 ("release" build). Spearated module_init()
changes were tested on sparc and sparc64 as well by martin@ (thanks!).

kernel refuse to mount a filesystem read-write (booting a system
multiuser with critical filesystems read-only is bad):
Add a check_wapbl() which will check some WAPBL values in the superblock,
and try to read the journal via wapbl_replay_start() if there is one.
pfatal() if one of these fail (abort boot if in preen mode,
as "CONTINUE" otherwise). In non-preen mode the bogus journal will
be cleared.
check_wapbl() is always called if the superblock supports WAPBL.
Even if FS_DOWAPBL is not there, there could be flags asking the
kernel to clear or create a log with bogus values which would cause the
kernel refuse to mount the filesystem.

addresses. Make the kernel support SIOC[SG]IFADDRPREF for IPv6
interface addresses.
In in6ifa_ifpforlinklocal(), consult preference numbers before
making an otherwise arbitrary choice of in6_ifaddr. Otherwise,
preference numbers are *not* consulted by the kernel, but that will
be rather easy for somebody with a little bit of free time to fix.
Please note that setting the preference number for a link-local
IPv6 address does not work right, yet, but that ought to be fixed
soon.
In support of the changes above,
1 Add a method to struct domain for "externalizing" a sockaddr, and
provide an implementation for IPv6. Expect more work in this area: it
may be more proper to say that the IPv6 implementation "internalizes"
a sockaddr. Add sockaddr_externalize().
2 Add a subroutine, sofamily(), that returns a struct socket's address
family or AF_UNSPEC.
3 Make a lot of IPv4-specific code generic, and move it from
sys/netinet/ to sys/net/ for re-use by IPv6 parts of the kernel and
ifconfig(8).

hosts and service names.
This default ifconfig behavior stays the same as it always was.

will not return any data and mount(2) fails with EINVAL if data_len
is 0. This caused lame-o output in mount -vv:
mount_fdesc: fdesc on /failsystem: Invalid argument
value to put a prop_string_t into the environment, but the keyword
parser put a prop_data_t into the environment, instead. That broke
the -vlanif and -carpdev keywords and defied developer expectations.
Let's put a prop_string_t into the environment.
Thanks to Arnaud Degroote for reporting the problem.
tested with a DEBUG+DIAGNOSTIC+LOCKDEBUG kernel. To summerise NiLFS, i'll
repeat my posting to tech-kern here:
NiLFS stands for New implementation of Logging File System; LFS done
right they claim :) It is at version 2 now and is being developed by NTT, the
Japanese telecom company and recently put into the linux source tree. See
http://www.nilfs.org. The on-disc format is not completely frozen and i expect
at least one minor revision to come in time.
The benefits of NiLFS are build-in fine-grained checkpointing, persistent
snapshots, multiple mounts and very large file and media support. Every
checkpoint can be transformed into a snapshot and v.v. It is said to perform
very well on flash media since it is not overwriting pieces apart from a
incidental update of the superblock, but that might change. It is accompanied
by a cleaner to clean up the segments and recover lost space.
My work is not a port of the linux code; its a new implementation. Porting the
code would be more work since its very linux oriented and never written to be
ported outside linux. The goal is to be fully interchangable. The code is non
intrusive to other parts of the kernel. It is also very light-weight.
The current state of the code is read-only access to both clean and dirty
NiLFS partitions. On mounting a dirty partition it rolls forward the log to
the last checkpoint. Full read-write support is however planned!
Just as the linux code, mount_nilfs allows for the `head' to be mounted
read/write and allows multiple read-only snapshots/checkpoint mounts next to
it.
By allowing the RW mount at a different snapshot for read-write it should be
possible eventually to revert back to a previous state; i.e. try to upgrade a
system and being able to revert to the exact state prior to the upgrade.
Compared to other FS's its pretty light-weight, suitable for embedded use and
on flash media. The read-only code is currently 17kb object code on
NetBSD/i386. I doubt the read-write code will surpass the 50 or 60. Compared
this to FFS being 156kb, UDF being 84 kb and NFS being 130kb. Run-time memory
usage is most likely not very different from other uses though maybe a bit
higher than FFS.
- Capitialize "Name" in World Wide Name.
- Print the World Wide Name if it exists.
- Use LBA48 maximum address when available for "total sectors" output.
- So that geometry will display on more drives, don't be as strict when
checking for non-ATAPI devices. (This seemed to be an issue on at least
one instance of a Caviar SE16 drive.)
- Check more carefully for valid/relevant queue depth before printing it.
- Increment the queue depth by one for display.
While here, wrap some long lines that I should have had wrapped before they
were commited in rev. 1.46.
partutil.c::getdiskinfo to use it to get disk geometry info.
Use DIOCGWEDGEINFO ioctl to get information about partition size, if disk
driver doesn't support it use old DIOCGDINFO. This patch adds support for
wedge like devices(lvm logical volumes, ZFS zvol partitions) to newfs and
other tools.
No objections on tech-userlevel@.

module. This is in preparation for having the kernel load an optional
<module>.prop alongside a module, which is useful for passing options
to autoloaded modules and modules loaded at boot time.
e.g,
umount -a -t nonfs,mfs
This makes it clear that the "no prefix" only needs to be on the first
file-system argument to -t. The mount(8) man page has a clear example
of this but for some reason umount(8) was missing one.
ifa_data member of every AF_LINK struct ifaddrs points at the
corresponding struct if_data. In ifconfig(8), do not try to suppress
duplicate AF_LINK ifaddrs by checking for a NULL ifa_data.
Don't copy out two AF_LINK struct ifaddrs for each active link-layer
address. getifaddrs(3) used to copy out one ifaddrs for the kernel's
RTM_IFINFO message, and one more for the kernel's RTM_NEWADDR message.
I suppress the first duplicate with a highly conservative change that
wastes a little bit of ifaddrs storage. The storage is not leaked.
'address: ' field, don't treat the first address as the active address,
but search the link-layer addresses for the ones flagged IFLR_ACTIVE,
and print those. Extract a subroutine, print_link_addresses(), for
printing link-layer addresses.
