I've made dpkg run at reasonable speeds on merulo. Here's how you can
do it too.
Put the following text in strncpy.c:
#define _GNU_SOURCE
#include <string.h>
char *strncpy(char *dest, const char *src, size_t n)
{
unsigned int m = strnlen(src, n);
memcpy(dest, src, m);
if (m < n) {
memset(dest + m, 0, n - m);
}
return dest;
}
Then compile it with:
gcc -W -Wall -ansi -pedantic -fPIC -shared -o strncpy.so strncpy.c
(I like my warnings.)
Now, become root using your favourite method and:
mv strncpy.so /etc
echo /etc/strncpy.so >>/etc/ld.so.preload
Now dpkg is pseudo-fixed. The real fix comes in two parts: glibc will be
updated to make strncpy not suck so much for this case, and dpkg will be
fixed to not use strncpy. I've Considered strncpy Harmful for a while,
and this has only confirmed my earlier thoughts :-)
Oh, if anyone spots a bug in the strncpy implementation above, do shout;
I knocked it up quickly and it WorksForMe so far.
