Bug#746310: libc6: strcmp returns false equality between two strings
Package: libc6
Version: 2.18-4
Severity: normal
Dear Maintainer,
While debugging a problem building the debian-installer,
we came across a case where strcmp reports 2 strings equality whereas they are
not.
It's the comparaison between 2 translated entries '.' and '..'
that are translated to the string \ and \0001 in the genisoimage program.
This program was complaining that '.' and '..' both translated to '' and thus
cannot generate iso.
This was obviously wrong, so I narrowed the check to this case:
--
cat test_strcmp.cEOF
#include stdio.h
#include stdlib.h
void main(void) {
char stra[2];
char strb[2];
int result = 0;
stra[0] = 0;
stra[1] = 0;
strb[0] = 1;
strb[1] = 0;
result = strcmp(stra,strb);
printf(result from strcmp('\\','\\0001' is %d)\n,result);
exit(0);
}
EOF
Building this program on sparc, 32bit or 64bit, optimized or not, the result is
0.
Patrick Bagget did some more investigation and found that any string composed
of a list of 1 followed by a 0 is miscompared.
Here's an example :
{ 0, 0 } //i.e. original test case. Fails, returns 0
{ 1, 0 }
{ 1, 0, 0 } //fails, returns 0.
{ 1, 1, 0 }
{ 1, 1, 0, 0 } //fails, returns 0.
{ 1, 1, 1, 0 }
{ 1, 1, 1, 0, 0 } //fails, returns 0.
{ 1, 1, 1, 1, 0 }
{ 1, 1, 1, 1, 0, 0 } //fails, returns 0.
{ 1, 1, 1, 1, 1, 0 }A
There's something wrong in the glibc implementation of strcmp for the case of
sparc, and sparc64.

Bug#427990: glibc: PIE executables core dumps on hppa
Package: glibc Severity: important Tags: patch start.S file is messing up the paramaters when using the -pie option. This causes instant segfault on hppa when trying to run an pie executable. This causes portmap and nscd to break on this arch and maybe many other executables. Here is a patch that fix the start problem, but all pie programs must be relinked to fix the segfault. -- System Information: Debian Release: lenny/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable') Architecture: hppa (parisc64) Kernel: Linux 2.6.18-4-parisc64 Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash --- ports/sysdeps/hppa/elf/start.S.orig 2007-06-02 12:27:53.0 +0200 +++ ports/sysdeps/hppa/elf/start.S 2007-06-02 12:27:49.0 +0200 @@ -96,16 +96,16 @@ _start: #if SHARED /* load main (1st argument) */ - addil LR'.Lpmain, %r19 - ldw RR'.Lpmain(%r1), %r26 + addil LT'.Lpmain, %r19 + ldw RT'.Lpmain(%r1), %r26 ldw 0(%r26),%r26 /* void (*init) (void) (4th argument) */ - addil LR'.Lp__libc_csu_init, %r19 - ldw RR'.Lp__libc_csu_init(%r1), %r23 + addil LT'.Lp__libc_csu_init, %r19 + ldw RT'.Lp__libc_csu_init(%r1), %r23 ldw 0(%r23), %r23 /* void (*fini) (void) (5th argument) */ - addil LR'.Lp__libc_csu_fini, %r19 - ldw RR'.Lp__libc_csu_fini(%r1), %r22 + addil LT'.Lp__libc_csu_fini, %r19 + ldw RT'.Lp__libc_csu_fini(%r1), %r22 ldw 0(%r22), %r22 #else /* load main (1st argument) */
