Description Artem 2015-02-20 15:39:03 CET

Unbound crashes when try to send SIGHUP
Problem occurs in util/config_file.c (1213):

1207 #ifdef HAVE_GETPWNAM
1208         /* translate username into uid and gid */
1209         if(cfg->username && cfg->username[0]) {
1210                 struct passwd *pwd;
1211                 if((pwd = getpwnam(cfg->username)) == NULL)
1212                         log_err("user '%s' does not exist.", cfg->username);
1213                 cfg->uid = pwd->pw_uid;
1214                 cfg->gid = pwd->pw_gid;
1215         }

If a copy of /etc/pwd.db is placed in working directory, the crash does not happen

Hi Artem,

Thank you for the bug report.  I have fixed this in svn trunk, it looks up the values once at startup like it did before. (the chroot is causing the issue, with chroot: "" it would workaround the issue).

Best regards,
   Wouter
