original releases were not numbered.)

af4d8ead38 The Common Error Description Library, developed by MIT SIPB and used by
a number of (ex-)Athena programs.  Breaking my own rules for importing
somewhat, as this code does not appear to be actively maintained by anyone
(not that it really needs it).

b6cc3bfac6 The enclosed patch fixes the Makefile contained in
share/doc/usd/{30.rogue,31.trek}: make fails if the games source
tree is not present (see the mail that I have sent yesterday).

        This patch makes the Makefiles test if the games source
tree is present.  If it is not present, the Makefiles default to
no operation.

[Note:  I'm not sure if the Makefile changes might not be collapsable into
a shorter format, but I'll just leave it this way for now and be safe -jkh]

314bc6245e The enclosed patch makes bsd.doc.mk consistent with bsd.prog.mk
when creating the obj link.  While bsd.prog.mk inconditionnaly creates
a link in /usr/obj, bsd.doc.mk tests if the source tree is contained in
/usr/src.  If so, it creates a link to /usr/obj.  If the source tree
is contained in another directory, bsd.doc.mk creates an obj subdirectory.

af8dd62b9a The enclosed patch is a cosmetic change to bsd.prog.mk. When
a program directory has subdirectories, make now prints "===> dir/subdir"
instead of "===> subdir".  This is modeled after the rules contained in
bsd.subdir.mk.

20415301cd Fix security holes in sigreturn(), ptrace() and procfs. sigreturn()
attempted to check for insecure and fatal eflags and segment
selectors, but missed many cases and got the IOPL check back to
front.  The other syscalls didn't check at all.

sys_process.c, machdep.c:
Only allow PT_WRITE_U to write to the registers (ordinary and FP).

psl.h, locore.s, machdep.c:
Eliminate PSL_MBZ, PSL_MBO and PSL_USERCLR.  We are not supposed
to assume anything about the reserved bits.  Use PSL_USERCHANGE
and PSL_KERNEL instead.  Rename PSL_USERSET to PSL_USER.

exception.s:
Define a private label for use by doreti when returning to user
mode fails.

machdep.c:
In syscalls, allow changing only the eflags that can be changed on
486's in user mode (no longer attempt to allow benign IOPL changes;
allow changing the nasty PSL_NT; don't allow changing the i586
bits).

Don't attempt to check all the cases involving invalid selectors
and %eip's.  Just check for privilege violations and let the invalid
things cause a trap.

procfs_machdep.c:
Call the ptrace register functions to do all the work for reading
and writing ordinary registers and for single stepping.

trap.c:
Ignore traps caused by PSL_NT being set.  Previously, users could
cause a fatal trap in user mode by setting PSL_NT and executing an
iret, and a fatal trap in kernel mode by setting PSL_NT and making
a syscall.  PSL_NT was cleared too late and not in enough modes to
fix the problem.

Make all traps in user mode (except T_NMI) nonfatal.

Recover from traps caused by attempting to load invalid user
registers in doreti by restarting the traps so that they appear to
occur in user mode.
---

Fix bogons that I noticed while fixing the above:

psl.h:
Fix some comments.

Uniformize idempotency ifdef.

exception.s, machdep.c:
Remove rsvd[0-14].  rsvd0 hasn't been reserved since the 486 came
out.  Replace rsvd0 by `align'.  rsvd[0-11] used wrong (magic
non-unique) trap numbers.  Replace rsvd[1-14] by rsvd.

locore.s:
Enable alignment check flag on 486's and 586's.

machdep.c:
Use a better type for kstack[].

Use TFREGP() to find the registers.

Reformat ptrace functions from SEF to something closer to KNF.

procfs_machdep.c:
The wrong pointer to the registers got fixed as a side effect.

Implement reading and writing of FP registers.

/proc/*/*regs now work (only) for processes that are in memory.

Clean up comments.

trap.c, trap.h:
Remove unused trap types.

9bf308efab Eliminate T_KDBTRAP, which will soon go away. It was only used for an
unreachable case label in kdb_trap().

Use the correct case labels in kdb_trap() so that normal ddb entry doesn't
print a message.

Change all printf's to db_printf's.  Now you can put a breakpoint at printf,
and ddb entry messages don't spam the syslog output.

Cosmetic:

Use ISPL() instead of magic numbers.

Don't compile the unused function kdb_kbd_trap().

Improve some asms.

Print the arg to Debugger().
