Functionality lost:
1. struct disklabel used to be updated to contain bsize, fsize, cpg.
This information was used to locate the alternative superblock in
the filesystem if the primary superblock was corrupted. We need
to find a new place to store this information if we need this
functionality.
2. On vax SMD drives that contained bad sector lists, the newfs program
knew how to get the offset and skip to the correct location in order
to place the label.
so that we don't run multiple fsck's on the same spindle at the same time!
- Add some partition getting utilities that are wedge aware (soon to be able
to use the native geometry ioctl), so that we can fsck wedges.

From FreeBSD, with some adjustements by Andrew Doran and me.
* Add lfs_balloc capability to the lfs library.
* Extend the Ifile if we run out of free inodes when creating lost+found.
* Don't roll forward if we have allocated a lost+found, to avoid
conflicts when adding new files in roll-forward.
* Make some messages slightly more verbose (e.g. include inode number,
and use pwarn() instead of printf() so the messages include the device
name when preening).
* Change superblock detection/avoidance to use the offset table in the
primary superblock, rather than looking at the contents.
* Be more verbose about various operations when passed the -d flag,
especially roll-forward.
* Be more careful about dirops during roll forward, since the cleaner can
sometimes write blocks from dirop vnodes. Detect and avoid this problem.
* Always check the free list, even if given -i; if we're going to write
it we have to check it first.
* Mark inodes dirty when blocks are found during roll forward, so the
inodes are written with the new block locations.
* Update size of inodes if blocks beyond EOF are found during roll
forward.
* Fix segment accounting for blocks and inodes found during roll
forward.
* Report statistics on roll forward: how many new/deleted/moved files
and how many updated blocks (or "nothing new").
* Don't care if the device being checked is really a device, if we have
been passed the -f flag (to facilitate automated testing).
* When writing to the disk, use the current time in the segment headers
rathern than time 0.
* When passed the -i flag, locate the partial segment containing the
Ifile inode and use that to calculate lfs_offset, lfs_curseg,
lfs_nextseg. (Again for automated testing.)
introduce fileassoc(9), a kernel interface for associating meta-data with
files using in-kernel memory. this is very similar to what we had in
veriexec till now, only abstracted so it can be used more easily by more
consumers.
this also prompted the redesign of the interface, making it work on vnodes
and mounts and not directly on devices and inodes. internally, we still
use file-id but that's gonna change soon... the interface will remain
consistent.
as a result, veriexec went under some heavy changes to conform to the new
interface. since we no longer use device numbers to identify file-systems,
the veriexec sysctl stuff changed too: kern.veriexec.count.dev_N is now
kern.veriexec.tableN.* where 'N' is NOT the device number but rather a
way to distinguish several mounts.
also worth noting is the plugging of unmount/delete operations
wrt/fileassoc and veriexec.

if the kernel does not set the interface up after we set an address,
do it explicitly, unless we (previously) set it down on user request.
This will allow the network drivers to be "fixed" while keeping visible

specify/see an interface name to be attached
- move description about link[0-2] flags from slattach(8) to sl(4)

so the reads don't always fail, and also be more careful not to read off
the end of the disk. If a read does fail, error out instead of silently
leaving the loop early (and possibly dividing by zero seconds), because
it means our idea of the disk size is wrong, or worse.
This fixes PR bin/33199.
How it works:
- after successful execution of /etc/rc, check the value of "init.root"
sysctl node, if it's different than "/", chroot() into its value and run
/etc/rc inside the chroot(),
- in single-user, return back to the original / file system.
Allows running with / file system on e.g., cgd(4), vnd(4) or ccd(4) volumes.
Idea first discussed with Matt Thomas, implemented by Jachym Holecek <freza
(at) liberouter.org> with some nitpicks by me. Successfully used by me for
almost a year with / on a cgd(4) volume (for more information about the setup
check ftp://ftp.NetBSD.org/pub/NetBSD/misc/salo/init-chroot/ ).
the list in order (ordering it on mount).
Regularize error messages: these are now all in ALL CAPS, with all hex
numbers (not reported in caps) prefixed by 0x. (The non-fsck-specific
messages are an exception to this all-caps rule.)
ERANGE has been raised. Just remove the extra checks, which were incorrect
anyway in almost all calls because they did not match their corresponding
strto*l function.
This caused mount_tmpfs to not catch some error cases in, e.g., i386, as
strtoll was returning LLONG_MAX instead of LONG_MAX, which are different
in this platform (but not on 64-bit ones).

1: Output size of partition and cylinder groups.
2: Follow with a progress-bar line of dots (scaled to finish at RH margin)
3: Include a single line of alternate suberblock addresses before progress
bar. Default for newfs.
4: Output lots of lines of alternate superblock numbers that scroll madly
up the screen.
If -N given, newfs/mount_mfs exits before displaying any progress bar.

were full then not enough bits were left for the inode allocation map.
Always put a multiple of 8 fragments (and non-zero) inodes into the eqns
so that answer is correct.
Fix the sum that may discard the last cylinder group if it isn't large enough
to contain all its inodes.

table. Useful if the disk has remapping drivers installed into it (such as
Ontrack Disk Manager).
Added as an option instead of automatic behavior to let the user scan any
of the two partition tables at will.
We can now delete an entry from the tables using
veriexecctl delete /path/to/file
or remove an entire table using
veriexecctl delete /mount_point
(any directory will work for the mount point it's on)
In particular the 'read' part plays 'hunt the disklabel' in order to get a
label into a local buffer - from where it can be displayed/edited.
The 'write' part makes a separate scan of the disk looking for places to
write the label.
The main changes are:
- It can no longer write the first 8k of the mbr to the pbr (or v.v.)
- All labels on the disk (that it can find) get updated during a write
- With -A all the labels are displayed (inc. those deleted by -D)
- Addition of -D which will delete (by one's complimenting dk_magic{2}) and
existing labels before writing labels to the expected locations.
- -v gives some verbose output to stderr, -vv more etc
A better basis for processing incorrect endian labels, or labels from other
architectures.
This closes a hole pointed out by Thor Lancelot Simon on tech-kern ~3
years ago.
The problem was with running binaries from remote storage, where our
kernel (and Veriexec) has no control over any changes to files.
An attacker could, after the fingerprint has been verified and
program loaded to memory, inject malicious code into the backing
store on the remote storage, followed by a forced flush, causing
a page-in of the malicious data from backing store, bypassing
integrity checks.

For directories that are out of reach (caller is in a chroot, target

instead.

Instead, merge all the relevant comments into the code. This includes
acknowledgements to Google's Summer of Code 2005 program (they were in the

requirement of the program.)
- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
file sys/nfs/nfs_export.c. The former was becoming large and its code
is always compiled, regardless of the build options. Using the latter,
the code is only compiled in when NFSSERVER is enabled. While doing this,
also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
path and a set of export entries. At the moment it can only clear the
exports list or append entries, one by one, but it is done in a way that
allows setting the whole set of entries atomically in the future (see the
comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
that it becomes file system agnostic. In fact, all this whole thing was
done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
exports initialization; done internally by the kernel when initializing
the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
subsystems can run arbitrary code upon receipt of specific VFS events.
At the moment, this only provides support for unmount and is used to
destroy NFS exports lists from the file systems being unmounted, though it
has room for extension.

was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.
The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.
Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.
