hi
in rev. 1.70 of i386/linux/linux_machdep.c you talk about:
revision 1.70
date: 2007/02/15 00:54:40; author: jkim; state: Exp;
lines: +58 -54
MFP4: 113025, 113146, 113177, 113203, 113500, 113546,
113570
- PROT_READ, PROT_WRITE, or PROT_EXEC implies PROT_READ and
PROT_EXEC.
Linux/ia64's i386 emulation layer does this and it complies
with Linux
header files. This fixes mmap05 LTP test case on amd64.
I have a few questions:
1) did you verify that PROT_WRITE implies PROT_READ in
linux/i386? I didnt
find any such place, only a comment in ia64 ia32 emulation
talking about this.
I think the ia64 might be wrong (does anybody uses ia32
emulation on ia64 at all?)
2) the mmap05 tests tries to mmap() file with PROT_NONE
prot. how is implying
PROT_READ when PROT_WRITE going to help that?
in the real i386 linux the only thing I see is that
PROT_READ implies PROT_EXEC.
nothing more.
thnx
roman
