mycroft 98fc96ea40 Add some commentary on the previous. 1995-01-15 01:15:04 +00:00
mycroft ecef8fddfa Remove PSL_USERCLR, and add a PSL_USERSTATIC. Change the bit descriptions to
more closely match the 386 manual.  (Probably the mnemonics should be changed,
too.)
1995-01-15 00:57:50 +00:00
mycroft c7c817b91a sigreturn() and ptrace() security violations will now trap. Deal with those
traps by looking at the instruction stream and the stack to see if it looks
like we're returning to user mode, and if so pop to the hooks in locore.s.
This will fail in the case where a pop %ds or pop %es faults when returning
from a fast interrupt, but this should not be possible.
1995-01-15 00:55:25 +00:00
mycroft 3e8850eab2 Enable CR0_AM on 486s. (We already handled the fault.) This would be more
useful if it applied to the kernel.
Avoid btrl when checking AST flag.
Add hooks to recover from errors during any INTRFASTEXIT and simulate a user-
level protection fault.
1995-01-15 00:52:21 +00:00
mycroft c26ad3af41 Cosmetic changes, and use db_printf() rather than printf(). 1995-01-15 00:46:38 +00:00
mycroft 8476bee7b5 Do the eflags security check in a cheaper way. Just check that the privilege
level of the return cs is correct; don't check the other selectors.  (Will
fault later if they are invalid.)
1995-01-15 00:44:19 +00:00
mycroft da79b43eae Move the existing frame pointer calculation into a separate helper function.
Eventually this should cause the child to be swapped in if necessary.
Do the eflags security check in cheaper way.
1995-01-15 00:42:01 +00:00
mycroft a2dafd0821 Avoid using btrl, and check astpending before the return cs, because it's
faster and usually false.
1995-01-15 00:36:37 +00:00
mycroft 396d1c1d0c Convert unspecified usec value to 0, per discussion with Rick. 1995-01-13 16:15:02 +00:00
