Fix a subtle ring0 escalation vulnerability in amd64, and implement a
mitigation against similar bugs.

The operations on segment registers can generate a page fault if there is
an issue when touching the in-memory gdt. Theoretically, it is never
supposed to happen, since the gdt is mapped correctly. However, in the
kernel we allow the gdt to be resized, and to do that, we allocate the
maximum amount of va needed by it, but only kenter a few pages until we
need more. Moreover, to avoid reloading the gdt each time we grow it, the
'size' field of gdtr is set to the maximum value. All of this means that
if a mov or iretq is done with a segment register whose index hits a page
that has not been kentered, a page fault is sent.

Such a page fault, if received in kernel mode, does not trigger a swapgs
on amd64; in other words, the kernel would be re-entered with the userland
tls.

And there just happens to be a place in compat_linux32 where the index of
%cs is controlled by userland, making it easy to trigger the page fault
and get kernel privileges.

The mitigation simply consists in abandoning the gdt_grow mechanism and
allocating/kentering the maximum size right away, in such a way that no
page fault can be triggered because of segment registers.

- Revert temporary local conversion introduced at rev 1.43.

PR/51517: Jay West: Tty settings not restored on exit
PR/51518: Jay West: prompt is interleaved with client output

Both these issues are caused by rl_restore_handler not DTRT; fix
it so that it kills the internal libedit state completely. This is
inefficient, but it works.

Also fix:
1. add append_history()/H_NSAVE_FP
2. call the rl_startup_hook before printing the first prompt as documented.
  callint it from rl_initialize breaks python, because the callback ends
  up being invoked before the readline module is installed, and we end up
  dereferencing a NULL pointer.
3. add el_resize_terminal.

When resizing nvi in xterm, a scroll region is set with the old size
which garbles the display.

The scroll region is set for a terminfo scroll operation and then
reset to the current window size. While xterm lets you clear a
scroll region, there is no way to do this in terminfo except by
resetting the terminal which has a visual side effect.

Xterm actually clears the scroll region as part of the resize but
that happens before a program gets the SIGWINCH signal. When nvi sees
the SIGWINCH signal, it exits the vi mode using a scroll operation to
tidy up the display before it reenters vi mode with the new window size.

This patch does two things:
- make nvi also invoke a previous SIGWINCH handler (not sufficient,
  but that's how curses wants it).
- skip the tidy up in case of a restart (avoids the scroll region)

Welcome to 8.99.2!

mount_procfs(8): removal of /proc/#/ctl and filesystem tracing feature

(kamil)

Remove the filesystem tracing feature

This is a legacy interface from 4.4BSD, and it was
introduced to overcome shortcomings of ptrace(2) at that time, which are
no longer relevant (performance). Today /proc/#/ctl offers a narrow
subset of ptrace(2) commands and is not applicable for modern
applications use beyond simplistic tracing scenarios.

This removal will simplify kernel internals. Users will still be able to
use all the other /proc files.

This change won't affect other procfs files neither Linux compat
features within mount_procfs(8). /proc/#/ctl isn't available on Linux.

Remove:
- /proc/#/ctl from mount_procfs(8)
- P_FSTRACE note from the documentation of ps(1)
- /proc/#/ctl and filesystem tracing documentation from mount_procfs(8)
- KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9)
- source code file miscfs/procfs/procfs_ctl.c
- PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h
- KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h
- PSL_FSTRACE (0x00010000) from sys/sys/proc.h
- P_FSTRACE (0x00010000) from sys/sys/sysctl.h

Reduce code complexity after removal of this functionality.

Update TODO.ptrace accordingly: remove two entries about /proc tracing.

Do not keep legacy notes as comments in the headers about removed
PSL_FSTRACE / P_FSTRACE, as this interface had little number of users
(close or equal to zero).

Proposed on tech-kern@.

All filesystem tracing utility users are encouraged to switch to ptrace(2).
