is NOT disarmed when wdogctl closes the watchdog device. The -x
mode protects against the case where the kernel kills wdogctl,
sshd, and other essential userland programs (due to memory exhaustion,
for example), lobotomizing a mission-critical NetBSD system and
necessitating an operator visit to reboot it.
commands to the controller.
Add a amrctl(8) control tool, which for now only allows to get status
from the adapter (status of adapter, logical volumes and and individual
drives).
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.
tons of input from yamt@, wrstuden@, martin@, and christos@.
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
behaviour the same. Part of fixing PR 30694.
- note that ifconfig(8) create subcommand is required before slattach(8)
- network addresses aren't defined by slattach(8) but ifconfig(8)
- Add a BUGS section in slattach(8) to note that currently there is no way to
specify/see an interface name to be attached
- move description about link[0-2] flags from slattach(8) to sl(4)
(rather than adding a new description...)
- move description about SLIP limitations to a new BUGS section in sl(4)
- remove inappropriate MLINKS of slip.8 to slattach.8
- create MLINKS of slip.4 to sl.4 instead
- add some more xrefs
Ok'ed by christos, and closes PR kern/33672 and PR bin/33923.
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again. Updated the ckckp
regression test to use the new semantics.
dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4). Fixed a couple
other problems with dump_lfs that manifested themselves during testing.
NetBSD Foundation Membership still pending.) This stack was written by

The stack includes support for rfcomm networking (networking via your
bluetooth enabled cell phone), hid devices (keyboards/mice), and headsets.
Drivers for both PCMCIA and USB bluetooth controllers are included.
