This patch gets rid of the undeterministic error reporting code done on return values of get(pw|gr)nam_r. With this patch, if the group record is not returned by the corresponding function this error is not considered fatal even if errno != 0. The error is logged in such case. --- src/util/util.c | 50 ++++++++++++++++++-------------------------------- 1 file changed, 18 insertions(+), 32 deletions(-) diff --git a/src/util/util.c b/src/util/util.c index 3f244f5..27af3c6 100644 --- a/src/util/util.c +++ b/src/util/util.c @@ -2530,23 +2530,16 @@ virGetUserIDByName(const char *name, uid_t *uid) } } - if (rc != 0) { - /* We explicitly test for the known error values returned by - * getpwnam_r as the manpage says: - * ERRORS - * 0 or ENOENT or ESRCH or EBADF or EPERM or ... - * The given name or uid was not found. - */ - if ((rc == EINTR) || (rc == EIO) || (rc == EMFILE) || - (rc == ENFILE) || (rc == ENOMEM)) { - virReportSystemError(rc, _("Failed to get user record for name '%s'"), - name); - goto cleanup; - } - } - if (!pw) { - VIR_DEBUG("User record for user '%s' does not exist", name); + if (rc != 0) { + char buf[1024]; + /* log the possible error from getpwnam_r.
