to modify the whole VLAN tags, but it is permitted to change 12-bit
VLAN identificators only. Reflect this fact on the appropriate man
pages.
Antti Kantee and Mihai Chelaru from #netbsd-code were helpful in
better understanding of VLAN stuff. Thank you!
include path: the normal header files now include the "SSP" ones (which one
should note are not really named right: SSP and FORTIFY_SOURCE are independent
features).
Disable USE_SSP on targets where the compiler doesn't support it at all
(mips, alpha) or it's known broken (sh3). But enable FORTIFY_SOURCE,
without SSP, on those platforms -- tested on mipsel.
(what other systems keep in libssp, we already have in libc) into libc
to match what other systems with FORTIFY_SOURCE do. Goodbye, libssp
dependency in libraries and executables. Discussed with christos and
mrg; Christos will merge the headers to get us the rest of the way to a
FORTIFY_SOURCE implementation that works as others' code expects.
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.
This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.
This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.
Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.
dmesgfs is another example file system, which displays the device tree
information gained from dmesg(8) as a directory hierarchy. The information
can be displayed in files, or as targets of symbolic links.

- remove cpu_exit.9.
- remove ctxsw.9 from makefile because it's too stale.
XXX maybe it will revive as mi_switch.9 later.
- add cpu_switchto.9 to makefile.
Introduce a parameter -r to control the root node type. For example
"dtfs -r 'lnk /etc' /puffs" mounts dtfs with the root node as a
symbolic link to /etc:
jojonaru# ./dtfs -r 'lnk /etc' /puffs
jojonaru# ls -l /puffs
lrw-rw-rw- 1 root wheel 4 May 17 14:06 /puffs -> /etc
jojonaru# cd /puffs
jojonaru# pwd
/etc
jojonaru#
Extra credit for figuring out how to unmount this file system with
umount(8).
Likewise, "dtfs -r 'chr 2 12' /puffs" makes /puffs (i386) /dev/zero etcetc.
Bug fixes:
- Fix crash reported by Scott Ellis on current-users@.
- Fix race conditions in enforcing the Veriexec rename and remove
policies. These are NOT security issues.
- Fix memory leak in rename handling when overwriting a monitored
file.
- Fix table deletion logic.
- Don't prevent query requests if not in learning mode.
KPI updates:
- fileassoc_table_run() now takes a cookie to pass to the callback.
- veriexec_table_add() was removed, it is now done internally. As a
result, there's no longer a need for VERIEXEC_TABLESIZE.
- veriexec_report() was removed, it is now internal.
- Perform sanity checks on the entry type, and enforce default type
in veriexec_file_add() rather than in veriexecctl.
- Add veriexec_flush(), used to delete all Veriexec tables, and
veriexec_dump(), used to fill an array with all Veriexec entries.
New features:
- Add a '-k' flag to veriexecctl, to keep the filenames in the kernel
database. This allows Veriexec to produce slightly more accurate
logs under certain circumstances. In the future, this can be either
replaced by vnode->pathname translation, or combined with it.
- Add a VERIEXEC_DUMP ioctl, to dump the entire Veriexec database.
This can be used to recover a database if the file was lost.
Example usage:
# veriexecctl dump > /etc/signatures
Note that only entries with the filename kept (that is, were loaded
with the '-k' flag) will be dumped.
Idea from Brett Lymn.
- Add a VERIEXEC_FLUSH ioctl, to delete all Veriexec entries. Sample
usage:
# veriexecctl flush
- Add a 'veriexec_flags' rc(8) variable, and make its default have
the '-k' flag. On systems using the default signatures file
(generaetd from running 'veriexecgen' with no arguments), this will
use additional 32kb of kernel memory on average.
- Add a '-e' flag to veriexecctl, to evaluate the fingerprint during
load. This is done automatically for files marked as 'untrusted'.
Misc. stuff:
- The code for veriexecctl was massively simplified as a result of
eliminating the need for VERIEXEC_TABLESIZE, and now uses a single
pass of the signatures file, making the loading somewhat faster.
- Lots of minor fixes found using the (still under development)
Veriexec regression testsuite.
- Some of the messages Veriexec prints were improved.
- Various documentation fixes.
All relevant man-pages were updated to reflect the above changes.
Binary compatibility with existing veriexecctl binaries is maintained.
controllers. These controllers can be found on add-on PCIe cards, or
on some motherboards to provide the PATA connectivity (e.g. some intel
ICH8-based motherboards).
Thanks to JMicron Technology for providing me documentation and
different sample boards for this work.
device controllers, and more specifically raid controllers.
Add a new sensor type, ENVSYS_DRIVE, to report drive status. From OpenBSD.
Add bio and sysmon support to mfi(4). This allow userland to query
status for drives and logical volumes attached to a mfi(4) controller. While
there fix some debug printfs in mfi so they compile.
Add bio(4) to amd64 and i386 GENERIC.
Note that the emulation root is linux32 when running i386 linux programs
on an amd64 system.
Note that paths that start /../ are only looked up in the real root.
Modify the bug/note about symlinks not being looked up in the emulation root.
Some of this stuff ought to be in a generic 'emulation' man page.
the Linux (BlueZ) API.
- L2CAP or RFCOMM connections can require the baseband radio link
mode be any of:
authenticated (devices are paired)
encrypted (implies authentication)
secured (encryption, plus generate new link key)
- for sockets, the mode is set using setsockopt(2) and the socket
connection will be aborted if the mode change fails.
- mode settings will be applied during connection establishment, and
for safety, we enter a wait state and will only proceed when the mode
settings are successfuly set.
- It is possible to change the mode on already open connections, but
not possible to guarantee that data already queued (from either end)
will not be delivered. (this is a feature, not a bug)
- bthidev(4) and rfcomm_sppd(1) support "auth", "encrypt" and
"secure" options
- btdevctl(8) by default enables "auth" for HIDs, and "encrypt" for
keyboards (which are required to support it)
intermediate directories have already been created. If not, then
create the intermediate directories. This means that callers don't
need to create the intermediate directories themselves.
When reading a virtual directory, don't return a zero-length
virtual directory entry.

mp3-based files according to artist, genre or year.
Three virtual directories are made available under the mount point -
artists/
genre/
year/
and then virtual directory entries (see virtdir(3)) are created under
these heading directories.
The pkgsrc/audio/id3 package is needed for this file system to function
properly.
Two shell scripts, id3info.sh and id3db.sh, are included to build up
the music database for id3fs to use to build up its virtual
directories.
librefuse-based file systems.
These are especially useful for file systems which present virtual
directory hierarchies to the caller.
The routines build up and manage an array of virtual directory
entries, indexed upon full pathname within the file system. This is
analogous to the way refuse indexes its own entries. Routines are
available to add, delete, and find entries. Each entry can be one of
3 types - file ('f'), directory ('d') or symbolic link ('l'). Each
entry can also be associated with a target, which is a character
string allocated upon addition. This can be useful for virtual
directory entries of the symbolic link type.
The virtual directory entries can be traversed as an ordered list
(the entries are ordered alphabetically), or can be accessed by
directory component, using routines analogous to opendir(3), readdir(3),
and closedir(3).
only take the bare essentials, which currently means removing
"maxreqlen" from the argument list (all current callers I'm aware
of set it as 0 anyway). Introduce puffs_init(), which provides a
context for setting various parameters and puffs_domount(), which
can be used to mount the file system. Keep puffs_mount() as a
shortcut for the above two for simple file systems.
Bump development ABI version to 13. After all, it's Friday the 13th.
Watch out! Bad things can happen on Friday the 13th. --No carrier--
accessors for interesting data in it. Namely, you can now get
pu->pu_privdata with puffs_getspecific(), pu->pu_pn_root with
puffs_set/getroot() and pu->pu_maxreqlen with puffs_getmaxreqlen().
by killing the parent process. The parent's PID is saved in $RC_PID.
* In all rc.d/* scripts that previously tried to stop the boot,
replace in-line code with "stop_boot".
* Document this.
This should fix PR 29822.
