This modification adds the capability to newsyslog to write the
rotation message in a format that is compliant with RFC5424. This
capability is enabled on a per-log file basis through a new value
("T") in the flags field in newsyslog.conf. This is useful on systems
that use the RFC5424 format for log files so that the rotation message
format matches that of the other log messages. There has been recent
mention of adding an RFC5424 compliant mode to syslogd and at least
one alternative system log daemon (rsyslogd) that already has the
capability to use that format.

ABI breakage is mitigated by providing compatibility using versioned
symbols, ingenious use of the existing padding in structures, and
by employing other tricks. Unfortunately, not everything can be
fixed, especially outside the base system. For instance, third-party
APIs which pass struct stat around are broken in backward and
forward incompatible ways.
Kinfo sysctl MIBs ABI is changed in backward-compatible way, but
there is no general mechanism to handle other sysctl MIBS which
return structures where the layout has changed. It was considered
that the breakage is either in the management interfaces, where we
usually allow ABI slip, or is not important.
Struct xvnode changed layout, no compat shims are provided.
For struct xtty, dev_t tty device member was reduced to uint32_t.
It was decided that keeping ABI compat in this case is more useful

manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to

With this change, support remains for some netgraph modules that don't

though ng_atmllc certainly stands alone.

This variable was used 4 times in 1 function and all uses were wrong.
The 4 uses were in he test_frame() (show) function, to try to restore
4 colors, 2 unnecessarily and these 2 now broken. This was wrong
because it is the previous colors that must be restored, but the global
holds the original colors. Excessive setting of colors at the end
restored the previous colors correctly in most cases, but I removed
this a couple of revisions ago.
Originally, this variable had 1 correct use, to test for being on a vty
as a side effect of initializing it. This is now down in init(), and
init() also leaves a better-named global with the same contents.
Fix this by reading the current console info into a local variable in
test_frame(), as is done for several other functions. Fix style bugs
in this reading for all callers:
- extra blank lines
- all error messages different. The first one now in init() is not as
specific as the old one, but it is after a different specific one for
another ioctl and is unlikely to be reached when the first ioctl
succeeds. Ones after the first are to repeat the ioctl, so are even
more likely to be reached. The correctness of full removal of the
old global depends on the error handling for failure to initialize
it being unreachable.
- err() instead of warn() for failure in load_font(). This is almost
unreachable, and it makes no sense to continue after undoing previous
changes with revert().
- unreachable return after err() for failure in dump_screen().
Undo large renaming of local variables from the good name 'info' to the
bad name _info, which was done to protect the buggy global's bad name
from -Wshadow warnings.
Change 25 uses of errc() to err(). 2 of these were correct. 23 used
errno for the arg so were just a verbose spelling of err(). 5 of these
were just style bugs, and 18 depended on revert() saving errno.
1 warn() also depended on revert() saving errno.
Remove 2 warnx()'s that duplicate the message from a later errx().
These used to be before returns, and should have reported errno in
some cases. errno is also not reported for for openguess() failures.
Only "restore" the video mode in revert() if the mode was just set
(necessarily partially). Setting the mode to its current setting
doesn't "restore" it, but resets it, with the least harmful change
being to clear the screen. revert() is called even for some harmless
syntax errors and usually did nothing except reset the mode. Now it
usually does nothing. The only things that it tries to restore apart
from the mode are the active vty number, the screen map, 2 colors that
only need to be restored (only after a mode change) to fix kernel bugs,
and 3 colors that can't be restored due to kernel bugs. (This is
mostly for sc, since vt doesn't support mode changes.)
revert() is not called for syntax and setting errors after [mode], so
the mode reset is only done for failures to set raster mode after
setting graphics mode. normal colors can only be set after [mode],
and that is why reverting them should be unnecessary.
r146736 added an undocumented syntax and many bugs handling it. The
documented syntax is "... [mode] [fg [bg]] [show]", where it is critical
for reducing ambiguity and keeping things simple that the mode is
parsed first. r146736 added buggy support for "... [mode] [fg [bg]]
[show] [mode] [fg [bg]]". One error was that after for failing to set
a partially-supported graphics mode, argv[optind] remains pointing to
the mode so doesn't match the first [fg [bg]], so the setting is
attempted again, with slightly worse error handling.
Fix this by removing it (support for the trailing '[mode] [fg [bg]]')
and cleaning up. The cleanups are mostly to remove convolutions and
bugs that didn't work to handle the ambiguous syntax '[fg [bg]] [fg [bg]]'
when [mode] and [show] are not present. Globals were set to allow
repeating the color settings at the end. The functions that set the
colors earlier were misnamed from set* to get*. All that they "got" is
is settings from argv. They applied the settings to the kernel and
the globals.
Fix restoration of colors in revert() by restoring 2 after the mode
change. Colors should not need to be restored, but a bug in scteken
clobbers them on any mode change, including ones for restoration. Don't
move the restoration of the other 3. Teken doesn't clobber them on
mode changes because it doesn't support them at all (sc still supports
the border color, but only using a non-teken ioctl).
Add restoration of colors after a successful mode change to work around
the scteken bug there too. The bug was previously masked by the general
setting of colors at the end.
Fix a longstanding parsing/error handling bug by exiting almost immediately
after matching the [mode] arg but failing to set the mode. Just revert
if necessary. Don't return to continue parsing but do it wrong. This
bug caused spamming the output with a usage() message and exiting with
status 1 whenever [mode] is not present bug [fg [bg]] or [show]. The
exit code 1 was actualy an ambiguous internal code for failure to match
[mode] or failure to set [mode]. This 1 was obfuscated by spelling it
EXIT_FAILURE, but actual exit codes spell EXIT_FAILURE as 1. Remove
another global which could have been used to disambiguate this but was
only used to micro-optimize the (unnecessary except for other bugs)
setting of colors at the end.
attempts to keep them that way. The bg brightness bit is interpreted
as blinking in some modes, but it would barely be useful to disallow
setting it when it would give blinking in code which knew when that
is. The old code mostly knew this wrong, and added handling errors.
It is in fact impossible to know, since future mode switches may
change the meaning of the bit many times on the screen and in history.
Old versions of vidcontrol disallowed bg color numbers >= 8 in all
cases. This is very VGA/syscons-centric. Syscons uses the VGA defaults
of blinking fg instead of bright bg in text mode and bright bg in
graphics mode. On VGA, this is very easy to toggle at any time, and
vt blows away the VGA text mode default at boot time.
r146736 changed this to try to allow bg color numbers in graphics mode
only. This is even more VGA/syscons-centric, and there are many bugs
in this, and many nearby bugs in the parser. These are increased or
decreased by differences and bugs in vt and teken.
Perhaps the most obvious bug was that almost any vidcontrol command
which changes any color or the mode causes an error if the initial fg
color is bright. E.g., in syscons text mode, after "vidcontrol
lightwhite" to make the fg bright, another "vidcontrol lightwhite" is
rejected and buggy fixup code changes the fg to white. This is because
the bright fg color creates a bright bg color for the phantom reverse
video attribute, so was rejected. (The reverse video attribute is
phantom because teken ignores the user's setting of it and simply
reverses the fg attributes to create the bg attributes. Sometimes
some layer masks off the brightness/blinking bit, but not here.)
Perhaps the next most obvious one was that "vidcontrol lightgreen
lightblue" was misparsed as 2 settings of the fg instead of 1 setting
of the fg and 1 invalid setting of the bg. This is because the
parser supports an undocumented syntax with many parsing bugs (an
ambiguity gives this one).
I recently fix bugs in teken that broke setting of bright fg's and
bg's in the normal way. This gave more settings of then, so the old
bugs showed up more often.
Multiple periodic scripts sleep for a random amount of time in order to
mitigate the thundering herd problem. This is bad, because the sum of
multiple uniformly distributed random variables approaches a normal
distribution, so the problem isn't mitigated as effectively as it would be
with a single sleep.
This change creates a single configurable anticongestion sleep. periodic
will only sleep if at least one script requires it, and it will never sleep
more than once per invocation. It also won't sleep if periodic was run
interactively, fixing an unrelated longstanding bug.
