miscemu/wine gets into the way in map_image

[Uwe Bonnes]

Hallo,

the full installer for XILINX Webpack 5.1 is a 160 MByte executable.
It doesn't start with wine:
> ~/tmp/wine/compile/wine/wine WebPACK_51_fcfull_i.exe
err:virtual:map_image Standard load address for a Win32 program (0x00400000)
not available - security-patched kernel ?
Clearly my kernel isn't "security-patched".

Printing out /proc/maps/self in this situation shows:
08048000-0805c000 r-xp 00000000 03:08 195157 /home/bon/tmp/wine/compile/wine-realclean/wine/miscemu/wine
0805c000-0805d000 rw-p 00013000 03:08 195157 /home/bon/tmp/wine/compile/wine-realclean/wine/miscemu/wine

An strace on wine shows the mmap call in map_image:
23236 mmap2(0x400000, 161087488, PROT_READ|PROT_WRITE|PROT_EXEC,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x404c2000

Adding 0x400000 and 161087488 gives someting in the 0x09d0000 range. This
overlaps with the wine executable itself and mmap2 can't satisfiy the request
in place.

Any ideas what to do about that?

Thanks
