Hi,
Starting in `libc6 2.29-5`, the Lintian test
`t/tags/checks/binaries/binaries-obsolete-des` fails in `unstable`:
cc -g -O2
-fdebug-prefix-map=/builds/lintian/lintian/debian/test-out/packages/tags/checks/binaries/binaries-obsolete-des/binaries-obsolete-des-1.0=.
-fstack-protector-strong -Wformat -Werror=format-security -Wl,-z,relro
-Wl,-z,now uses-fcrypt.o -o uses-fcrypt -lcrypt
/usr/bin/ld: uses-fcrypt.o: in function `main':
./uses-fcrypt.c:19: undefined reference to `fcrypt'
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile:34: uses-fcrypt] Error 1
Perhaps is it time to remove the test (and the tag
`obsolete-des-encryption`). Was `fcrypt` dropped entirely, or is it
still provided by `libcrypt`?
I do not understand the impact of this commit:
https://salsa.debian.org/glibc-team/glibc/commit/e1dc23943b0a5c9e0612f8e1364a37f12b6710ef
Here is the code that did not link:
/* This program uses the obsolete function 'fcrypt',
which is an alias for 'crypt'. */
#include <crypt.h>
#include <stdio.h>
/* The prototype may already have been removed from crypt.h. */
extern char *fcrypt(const char *, const char *);
/* It may already not be possible to link new programs that use
'fcrypt' without special magic. */
#ifdef SYMVER
__asm__ (".symver fcrypt, fcrypt@" SYMVER);
#endif
int
main(void)
{
puts(fcrypt("password", "Dn"));
return 0;
}
Thanks for your guidance!
Kind regards,
Felix Lechner
