Early errors during start of libvirtd didn't have an error reporting mechanism and caused libvirtd to exit silently (only the return value indicated an error). Libvirt logging is initialized very early using enviroment variables and the internal error reporting API is used to report early errors. v2 changes: - print errors unconditionaly before logging starts - fix message to US spelling v2.5 changes: - initialize logging from enviroment - log all early errors using VIR_ERROR fixes: https://bugzilla.redhat.com/show_bug.cgi?id=728654 --- daemon/libvirtd.c | 41 ++++++++++++++++++++++++++++++----------- 1 files changed, 30 insertions(+), 11 deletions(-) diff --git a/daemon/libvirtd.c b/daemon/libvirtd.c index 53f1002..aa69f80 100644 --- a/daemon/libvirtd.c +++ b/daemon/libvirtd.c @@ -1285,11 +1285,14 @@ int main(int argc, char **argv) { {0, 0, 0, 0} }; + /* initialize early logging */ + virLogSetFromEnv(); + if (setlocale (LC_ALL, "") == NULL || bindtextdomain (PACKAGE, LOCALEDIR) == NULL || textdomain(PACKAGE) == NULL || virInitialize() < 0) { - fprintf(stderr, _("%s: initialization failed\n"), argv[0]); + VIR_ERROR(_("%s: initialization failed"), argv[0]); exit(EXIT_FAILURE); } @@ -1328,14 +1331,18 @@ int main(int argc, char **argv) { case 'p': VIR_FREE(pid_file); - if (!(pid_file = strdup(optarg))) + if (!(pid_file = strdup(optarg))) { + VIR_ERROR(_("Can't allocate memory")); exit(EXIT_FAILURE); + } break; case 'f': VIR_FREE(remote_config_file); - if (!(remote_config_file = strdup(optarg))) + if (!(remote_config_file = strdup(optarg))) { + VIR_ERROR(_("Can't allocate memory")); exit(EXIT_FAILURE); + } break; case OPT_VERSION: @@ -1347,27 +1354,33 @@ int main(int argc, char **argv) { return 2; default: - fprintf (stderr, _("%s: internal error: unknown flag: %c\n"), - argv[0], c); + VIR_ERROR(_("%s: internal error: unknown flag: %c"), + argv[0], c); exit (EXIT_FAILURE); } } - if (!(config = daemonConfigNew(privileged))) + if (!(config = daemonConfigNew(privileged))) { + VIR_ERROR(_("Can't create initial configuration")); exit(EXIT_FAILURE); + } /* No explicit config, so try and find a default one */ if (remote_config_file == NULL) { implicit_conf = true; if (daemonConfigFilePath(privileged, - &remote_config_file) < 0) + &remote_config_file) < 0) { + VIR_ERROR(_("Can't determine config path")); exit(EXIT_FAILURE); + } } /* Read the config file if it exists*/ if (remote_config_file && - daemonConfigLoad(config, remote_config_file, implicit_conf) < 0) + daemonConfigLoad(config, remote_config_file, implicit_conf) < 0) { + VIR_ERROR(_("Can't load config file '%s'"), remote_config_file); exit(EXIT_FAILURE); + } if (config->host_uuid && virSetHostUUIDStr(config->host_uuid) < 0) { @@ -1375,19 +1388,25 @@ int main(int argc, char **argv) { exit(EXIT_FAILURE); } - if (daemonSetupLogging(config, privileged, verbose, godaemon) < 0) + if (daemonSetupLogging(config, privileged, verbose, godaemon) < 0) { + VIR_ERROR(_("Can't initialize logging")); exit(EXIT_FAILURE); + } if (!pid_file && privileged && daemonPidFilePath(privileged, - &pid_file) < 0) + &pid_file) < 0) { + VIR_ERROR(_("Can't determine pid file path.")); exit(EXIT_FAILURE); + } if (daemonUnixSocketPaths(config, privileged, &sock_file, - &sock_file_ro) < 0) + &sock_file_ro) < 0) { + VIR_ERROR(_("Can't determine socket paths")); exit(EXIT_FAILURE); + } if (godaemon) { char ebuf[1024]; -- 1.7.6
