PC-BSD/trueos 1e1408asys/conf NOTES

Quick fix for building LINT on i386.  A fix is needed on all arches and
this one should also work on amd64 and sparc64.

LINT was broken in r312910 with the removal of pc98 support, by changing
the pathname in UKBD_DFLT_KEYBAP from a removed pc98 file to a nonexistent
file.

There are many bugs nearby.  Some are:
- the error is not properly detected and handled by make(1), because
  kbdcontrol(8) exits with status 0 after failing to find the keymap file
- UKBD_DFLT_KEYBAP is supposed to be MI, and is in MI NOTES to try enforce
  this, but 5 out of 8 arches don't support it
- LINT seems to have been broken by this in only 7 out of 8 arches.  mips
  breaks test coverage instead, by killing this option in its MD NOTES.
  arm kills ukbd but that is not enough to configure an unsupported option
  used only by ukbd.

PC-BSD/trueos d68a469share/man/man4 syscons.4, sys/conf files NOTES

Connect the restored dumb and sc terminal emulators to the kernel build.
Add or fix options to control static and dynamic configuration.  Keep
the default of scteken, but default to statically configuring all available
emulators (now 3 instead of 1).

The dumb emulator is almost usable.  libedit and libreadline handle
dumb terminals perfectly for at least shell history.  less(1) works
as well as possible except on exit.  But curses programs make messes.
The dumb emulator has strange color support, with 2 dumb colors for
normal output but fancy colorization for the cursor, mouse pointer and
(with a non-dumb initial emulator) for low-level console output.

Using the sc emulator instead of the default of scteken fixes at least
the following bugs:
- NUL is a printing character in cons25 but not in teken
- teken doesn't support fixed colors for "reverse" video.
- The best versions of sc are about 10 times faster than scteken (for
  printing to the frame buffer).  This version is only about 5 times
  faster.

Fix configuration features:
- make SC_DFLT_TERM (for setting the initial emulator) a normal option.

Add configuration features:
- negative options SC_NO_TERM_* for omitting emulators in the static config.

Fix a tracepoint lookup race in fasttrap_pid_probe().

fasttrap hooks the userspace breakpoint handler; the hook looks up the
breakpoint address in a hash table of tracepoints.  It is possible for
the tracepoint to be removed by a different thread in between the
breakpoint trap and the hash table lookup, in which case SIGTRAP gets
delivered to the target process.  Fix the problem by adding a
per-process generation counter that gets incremented when a tracepoint
belonging to that process is removed.  Then, when a lookup fails, the
trapping instruction is restarted if the thread's counter doesn't match
that of the process.

scp: validate filenames provided by server against wildcard in client

OpenSSH-portable commits:

check in scp client that filenames sent during remote->local directory
copies satisfy the wildcard specified by the user.

This checking provides some protection against a malicious server
sending unexpected filenames, but it comes at a risk of rejecting wanted
files due to differences between client and server wildcard expansion rules.

For this reason, this also adds a new -T flag to disable the check.

PC-BSD/trueos 543fd0fsys/dev/syscons scterm-dumb.c scterm-sc.c

Fix the dumb and sc terminal emulators to compile and work.

First remove ifdefs of the unsupported option SC_DUMB_TERMINAL which
prevented building using both in the same kernel and broke regression
tests.  This option will be replaced by per-emulator supported options.

The dumb emulator rotted with KSE in r83366, but usually compiled since
it is ifdefed to nothing unless SC_DUMB_TERMINAL is defined.  The type
of an unused function parameter changed.

Both emulators rotted when 2 new methods were added while the emulators
were removed.  Only null methods are needed, but null function pointers
give panics instead.

The wildcard in the default for the unsupported option SC_DFLT_TERM
never really worked.  It tends to prefer the dumb emulator when multiple
emulators are configured.  Change it to prefer scteken for compatibility.
