The cursor is only inside the scrolling region when we are in origin
mode. In that case, it should use originreg instead of scrollreg. It is
completely valid to place the cursor outside the scrolling region.
the field in the mbuf constructors, since otherwise we have no way to
tell if they are valid. In the future, Kip has plans to add a flag
specifically to indicate validity, which is the preferred model.
whole KVA space using one locked 4MB dTLB entry per GB of physical
memory. On Cheetah-class machines only the dt16 can hold locked
entries though, which would be completely consumed for the kernel
TSB on machines with >= 16GB. Therefore limit the KVA space to use
no more than half of the lockable dTLB slots, given that we need
them also for other things.
- Add sanity checks which ensure that we don't exhaust the (lockable)
TLB slots.
Some time ago I started working on a library called libteken, which is
terminal emulator. It does not buffer any screen contents, but only
keeps terminal state, such as cursor position, attributes, etc. It
should implement all escape sequences that are implemented by the
cons25 terminal emulator, but also a fair amount of sequences that are
present in VT100 and xterm.
A lot of random notes, which could be of interest to users/developers:
- Even though I'm leaving the terminal type set to `cons25', users can
do experiments with placing `xterm-color' in /etc/ttys. Because we
only implement a subset of features of xterm, this may cause
artifacts. We should consider extending libteken, because in my
opinion xterm is the way to go. Some missing features:
- Keypad application mode (DECKPAM)
- Character sets (SCS)
- libteken is filled with a fair amount of assertions, but unfortunately
we cannot go into the debugger anymore if we fail them. I've done
development of this library almost entirely in userspace. In
sys/dev/syscons/teken there are two applications that can be helpful
when debugging the code:
- teken_demo: a terminal emulator that can be started from a regular
xterm that emulates a terminal using libteken. This application can
be very useful to debug any rendering issues.
- teken_stress: a stress testing application that emulates random
terminal output. libteken has literally survived multiple terabytes
of random input.
- libteken also includes support for UTF-8, but unfortunately our input
layer and font renderer don't support this. If users want to
experiment with UTF-8 support, they can enable `TEKEN_UTF8' in
teken.h. If you recompile your kernel or the teken_demo application,
you can hold some nice experiments.
- I've left PC98 the way it is right now. The PC98 platform has a custom
syscons renderer, which supports some form of localised input. Maybe
we should port PC98 to libteken by the time syscons supports UTF-8?
- I've removed the `dumb' terminal emulator. It has been broken for
years. It hasn't survived the `struct proc' -> `struct thread'
conversion.
- To prevent confusion among people that want to hack on libteken:
unlike syscons, the state machines that parse the escape sequences are
machine generated. This means that if you want to add new escape
sequences, you have to add an entry to the `sequences' file. This will
cause new entries to be added to `teken_state.h'.
- Any rendering artifacts that didn't occur prior to this commit are by
accident. They should be reported to me, so I can fix them.

====================
1. List the command line options in a more standard way
2. Improve the explanations of some of the arguments (-A, -D)
3. Add ARCHSTRING and MTREEDB to the example rc file
4. Re-sort some of the examples according to the existing distinction
of "has a command line version" vs. "does not have a command line version"
Document changes for r186678
===========================
1. /usr/src/etc -> /usr/src where needed [1]
2. Add IGNORE_FILES to the example rc [2] (and remove IGNORE_MOTD)
3. Update the EXIT STATUS section for [3] and [4]
Update Copyright and .Dd accordingly

=======================
1. Various improvements to the mtree (-U) feature:
a. Seperate the notion of directory and file (user can override db path)
b. Only check for the existence of the mtree file if -U is set
c. Use mktemp to create the new version of the file
d. More safely install the new file
e. Standardize error messages a bit
2. Remove the last of the MAKEDEV stuff (RIP)
New Features
============
1. Switch to using the top level (e.g., /usr/src) Makefile, and specify
that we should use the *.mk files from the source directory instead of
the installed versions. [1][2] This allows easier cross builds and
simplifies (or in some cases permits) upgrading.
2. Check for the deprecated 'nodev' option in /etc/fstab [3]
3. Add support for the IGNORE_FILES variable [4] and deprecate IGNORE_MOTD
accordingly.
4. Before installing a file check to make sure that the target does not
already exist as a directory [5]
5. Check to be sure that the file installed and error out if not

that differ only by VCS Id) for the following reasons:
1. It was added without my consent, review, or even a heads up
2. It is something that I've repeatedly said I do not want, and certainly
do not want as the default
3. It is poorly implemented (much too complex, produces false positives
e.g., /etc/mail/helpfile)
Given that this is a situation that comes up very infrequently (usually
only for a major version upgrade) and can usually be handled simply
enough on a one-off basis, I will once again point out that I think
this is a Bad Idea. I would be willing to consider a better implementation
as an option that is off by default.

but the implementation here is very broken and causes strange
problems, so disable it for now.
Thanks to Simon L. Nielsen for reporting this problem.
When sysctl() is being called with a buffer that is too small, it will
return ENOMEM. Unfortunately the changes I made the other day sets the
error number to 0, because it just returns the error number of the
copyout(). Revert this part of the change.

options are presented so no boot manager is first in the list (and
hence more or less the default).
This area will probably be rototilled more before 8.0 comes out.

OpenBSM 1.1 alpha 4
- With the addition of BSM error number mapping, we also need to map the
local error number passed to audit_submit(3) to a BSM error number,
rather than have the caller perform that conversion.
- Reallocate user audit events to avoid collisions with Solaris; adopt a
more formal allocation scheme, and add some events allocated in Solaris
that will be of immediate use on other platforms.
- Add an event for Calife.
- Add au_strerror(3), which allows generating strings for BSM errors
directly, rather than requiring applications to map to the local error
space, which might not be able to entirely represent the BSM error
number space.
- Major auditd rewrite for launchd(8) support. Add libauditd library
that is shared between launchd and auditd.
- Add AUDIT_TRIGGER_INITIALIZE trigger (sent via 'audit -i') for
(re)starting auditing under launchd(8) on Mac OS X.
- Add 'current' symlink to active audit trail.
- Add crash recovery of previous audit trail file when detected on audit
startup that it has not been properly terminated.
- Add the event AUE_audit_recovery to indicated when an audit trail file
has been recovered from not being properly terminated. This event is
stored in the new audit trail file and includes the path of recovered
audit trail file.
- Mac OS X and FreeBSD dependent code in auditd.c is separated into
auditd_darwin.c and auditd_fbsd.c files.
- Add an event for the posix_spawn(2) and fsgetpath(2) Mac OS X system
calls.
- For Mac OS X, we use ASL(3) instead of syslog(3) for logging.
- Add support for NOTICE level logging.
OpenBSM 1.1 alpha 3
- Add two new functions, au_bsm_to_errno() and au_errno_to_bsm(), to map
between BSM error numbers (largely the Solaris definitions) and local
errno(2) values for 32-bit and 64-bit return tokens. This is required
as operating systems don't agree on some of the values of more recent
error numbers.
- Fix a bug how au_to_exec_args(3) and au_to_exec_env(3) calculates the
total size for the token. This buge.
- Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.
vm_map_lookup{,_locked}() to vm_map_lookup_entry(). Having the fast path
in vm_map_lookup{,_locked}() limits its benefits to page faults. Moving
it to vm_map_lookup_entry() extends its benefits to other operations on
the vm map.
