Subject: [9.20] fix: dev: Fix inverted gethostname() check in rndc status
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5ede4a87eb0889fc41430a04e58983c6abfdf44a;p=thirdparty%2Fbind9.git

[9.20] fix: dev: Fix inverted gethostname() check in rndc status

The replacement of named_os_gethostname() with raw gethostname()
inverted the success check: the "localhost" fallback runs on success,
and on failure the uninitialized hostname buffer is read by snprintf(),
leaking stack memory via the rndc status reply.

Closes #5889
