Michal Nowak 62670aa1b7 Fix a false positive compiler warning/error on Alpine 3.24 ... On Alpine Linux 3.24, GCC 15 with fortify-headers produces a compiler warning when building bin/nsupdate/nsupdate.c: In function 'fgets', inlined from 'get_next_command' at ../bin/nsupdate/nsupdate.c:2414:13: /usr/include/fortify/stdio.h:48:16: error: 'cmdlinebuf' may be used uninitialized [-Werror=maybe-uninitialized] 48 | return __orig_fgets(__s, __n, __f); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/fortify/stdio.h:42:1: note: in a call to '*fgets' declared with attribute 'access (read_write, 1, 2)' here 42 | _FORTIFY_FN(fgets) char *fgets(char * _FORTIFY_POS0 __s, int __n, FILE *__f) | ^~~~~~~~~~~ ../bin/nsupdate/nsupdate.c:2405:14: note: 'cmdlinebuf' declared here 2405 | char cmdlinebuf[MAXCMD]; | ^~~~~~~~~~ This is a false positive, because fgets() only writes into the buffer; the fortify-headers wrapper annotates the buffer argument with 'access (read_write, ...)', which makes GCC treat passing an uninitialized buffer as a read of uninitialized memory. Initialize the 'cmdlinebuf' buffer anyway to avoid the build error. Assisted-by: Claude:claude-fable-5		2026-06-24 17:44:42 +02:00
