| 有効/無効設定 | このワーニングクラスのチェックはデフォルトで無効になっています。チェックを有効にするにはプロジェクト設定ファイル
（configuration file）に以下の WARNING_FILTER ルールを追加してください。
WARNING_FILTER += allow class="Tainted Configuration Setting" |
#include <stdio.h> #include <stdlib.h> #include <unistd.h> /* sethostid() is not present in all versions of unistd.h. * When present, it is only available to the superuser. */ int sethostid(long hostid); int set_specified_hostid(FILE *f){ char hostid[16]; if (fgets(hostid, 16, f) == NULL ) return -1; return sethostid(atol(hostid)); /* 'Tainted Configuration Setting' warning issued here */ }
CodeSonar ships with library models that allow it to functions such as libc sethostid() and Win32 sethostid() that use one or more of their parameters to construct a configuration setting. If one of these functions is called with a potentially-tainted value in one of those parameter positions, a warning will be issued.
If you have created a custom library model for some function f() in terms of one of these existing models, calls to f() will also be capable of triggering Tainted Configuration Setting warnings.
