[LTP] getpeername01, getsockname01, socketpair01

[Michal Simek <michal.simek@petalogix.com>]

Hi,

Can someone explain me why is in that subject tests for invalid pointer
choose
address 1 (or 7 in socketpair01)? I did some tests on Microblaze and for
this address I am getting segfault.
That's the reason why I think that problem is in glibc or ltp test. All
tests test reaction for invalid pointer address.

The interesting is that any address from 1 to 999 9999 caused segfault.
Address above not.
Below is memory map but first segment starts at 0x1000 0000 not 1000
0000 which is in patches below and works.

# cat /proc/66/maps
10000000-10001000 r-xp 00000000 00:01 394        /opcoded
10001000-10002000 rw-p 00000000 00:01 394        /opcoded
48000000-4801c000 r-xp 00000000 00:01 389        /lib/ld-2.3.3.so
4801c000-4801e000 rw-p 0001b000 00:01 389        /lib/ld-2.3.3.so
4801e000-4817c000 r-xp 00000000 00:01 379        /lib/libc-2.3.3.so
4817c000-4817f000 r--p 0015d000 00:01 379        /lib/libc-2.3.3.so
4817f000-48181000 rw-p 00160000 00:01 379        /lib/libc-2.3.3.so
48181000-48186000 rw-p 00000000 00:00 0
bfc15000-bfc2a000 rwxp 00000000 00:00 0          [stack]


Below are my changes which jump over segfault but they are still invalid
pointer.
Has someone ever met with this problem before?

Patches below are on this link too.
