AMX support (#212) 2024-01-10 20:13:25 +02:00
Volker Ruppert
cfa7276cb9 Added support for driving the VGA display update timer with VSYNC. 
- Using the special value of 0 enables this feature. In that case the vertical
  frequency is used for the display updates. The update() method is called at
  the "vertical retrace end" time and sets the time of the display start. This
  value is used to set the vertical retrace indicator in VGA register 0x03da.
- This feature is not yet enabled if Voodoo support is present. The Voodoo device
  has it's own vertical timer and needs some more testing and possibly some changes.

Fix niclist.exe crash when writing to string returned by PACKET.DLL (#179) 
Seemingly Npcap returns a read-only string and `niclist.exe` tries to
modify (tokenize) it using `strtrok()`.
That results in the crash: #161

Probably related to
https://github.com/the-tcpdump-group/libpcap/pull/949.

Here is my try at fixing this.
For successful modification I propose to use a stack-allocated copy
instead of the original (const) version string.

Now
[packetWin7/Dll/Packet32.cpp#L159](https://github.com/nmap/npcap/blob/a41bc6a/packetWin7/Dll/Packet32.cpp#L159)
seems to initialize `const char PacketLibraryVersion[]` from the define
`WINPCAP_VER_STRING`, which seems to be of arbitrary length:
```
__declspec(dllexport) const char PacketLibraryVersion[] = WINPCAP_VER_STRING; 
```

Let's search for the longest string present in their repo:
```
$ git log -u version.h | awk 'BEGIN { FPAT="(([^ \t]+)?(\"[^\"]+\")?)+" } /^.*define.+WINPCAP_VER_STRING.+[0-9]/ { gsub(/"/, "", $NF); print $NF }' | sort -Vu | while read; do printf "%4s    %s\n" ${#REPLY} "${REPLY}"; done | sort -n

```

So it's 10 characters. (Sorry for the long Bash one-liner)

Also I visited the older code from WinPcap, and it seems it used a
64-byte long string:
[packetNtx/Dll/Packet32.c#L105](https://github.com/wireshark/winpcap/blob/267327e/packetNtx/Dll/Packet32.c#L105)
```
char PacketLibraryVersion[64]; 
```

So I assumed it's safe to allocate the same on stack.

These changes only have an effect when using a BIOS image designed for

Porting #SF patch #565 Real Time Clock /CMOS fix (#4) 
by Michele Giacomone

Detailed description:

  -Observed issues

   Due to some limitations only dates between 1980 and 2038 can be
   used in a reliable way.
   Also, bochs incorrectly assumes a linear correspondence between
   the data returned by the <time.h> functions localtime() and
   mktime(), and isn't setting the latter properly.
   Bochs keeps its internal time value dependent to these functions
   after setup, assuming that their internal settings won't change
   on the go - which is not the case.
   In my OS, and in my timezone, this leads to incorrect startup values
   for 5 months each year and unreliable values if the simulation is
   kept going for a long time. (a feedback between localtime() and
   mktime() is created which keeps shifting back the time)
   Also, the RTC simulation is not realistic since the clock fixes
   itself across DST changes, without updating any DST related flag,
   a behavior that no guest OS expects.

  -Proposed fix

   This is implemented in such way that no bochs' previous behavior
   is changed, a part from the broken ones, with legacy in mind
   == the user can keep using bochs exactly as before knowing nothing
      of this patch

   +Make the internal s.timeval variable a Bit64s, so it can fit all
    values that the cmos can correctly represent, reported below:
    MIN     setting  -62167219200 =>  0000/01/01 SAT  0:00:00
    MAX BCD setting  253402300799 =>  9999/12/31 FRI 23:59:59
    MAX BIN setting  745690751999 => 25599/12/31 FRI 23:59:59
    And then fix each reference to these so it can handle such values
    And make bochs correctly wrap around for under/overflows, so that
    only the most significant bits of the century are lost.

   +Do the same thing to the bochs time0 parameter, so all the above
    values can be chosen at startup (despite being now legal values,
    1 and 2 will still be treated as "local" and "utc"). Note that
    normally only BCD settings are valid since bochs' CMOS defaults
    to such operating mode - the only way to use the binary range
    is by loading a cmos memory map.

   +Make the internal s.timeval variable independent from external
    factors. This means providing a small set of time handling
    functions, contained in "iodev/utctime.h", which must work in
    any environment in which bochs compiles, accessing no external
    resource. This also means that after startup, s.timeval will only
    be changed internally, and no call to the OS time functions will
    be made.

   +Make the internal s.timeval variable timezone independent, to
    have a linear correlation between its values and valid CMOS
    settings. To make it easier, s.timeval is gonna be treated as
    if the current timezone was UTC: so,
     - if the user selects UTC as time0, s.timeval will become current
       time(NULL)
     - if the user selects localtime, s.timeval will be computed as
       the value which will display the same broken down time as
       localtime(&now)
     - if the user inputs a time formatted string the proper s.timeval
       to displayed will be easily calculated,
     - if the user inputs a starting time value, s.timeval will be
       computed as the value which will display the same broken down
       time as localtime(&user_input) to ensure the same operation as
       before.
    A "tz=utc" is displayed when bochs prints out the current time
    value, to warn users about the difference in meaning between the
    internally kept time value and the value they can set through
    the "time0=" parameter. This might be changed to communicate
    instead the time value they can input to get the same setting,
    but performing such calculation (except for the startup time)
    suffers from all the mktime()/localtime() problems listed above
    so I did not do it.
    The range of "time0" is automatically adjusted so all users in
    all time zones can set any legal value despite "time0=" having a
    local meaning.

  A thorough explanation of what I did and why can be found in the
  "iodev/utctime.h" library header.

591e2aa79f bugfix: when CET was not compiled in the emulation behavior of non-CET CPU was altered 
CET 'change' some x86 behavior
For example EPTP[7] become not-reserved and write to it not fail anymore
VMX doesn't check error code for CP exception if CET is enabled
These behaviors these changed even when CET was not compiled in

reset status bar items at reset (#142) 
When the user presses the "Reset" button on the gui ribbon, we need to
clear the active status of all statusbar items or they remain set after
the reset occurs.
