Package: tmux Version: 2.8-3 Severity: normal Tags: upstream patch Hello,
Starting with a running tmux session that is attachable as expected: uwe@taurus:~$ chmod o+x /tmp/tmux-$(id -u) uwe@taurus:~$ tmux a error creating /tmp/tmux-1000 (Permission denied) This error message is misleading, as the directory exists just fine. unstable and experimental are also affected. To improve this, the following patch helps: diff --git a/tmux.c b/tmux.c index 5b73079ee7b3..f11e5dc56136 100644 --- a/tmux.c +++ b/tmux.c @@ -134,12 +134,12 @@ make_label(const char *label, char **cause) if (lstat(resolved, &sb) != 0) goto fail; if (!S_ISDIR(sb.st_mode)) { - errno = ENOTDIR; - goto fail; + xasprintf(cause, "%s is not a directory", resolved); + return NULL; } if (sb.st_uid != uid || (sb.st_mode & S_IRWXO) != 0) { - errno = EACCES; - goto fail; + xasprintf(cause, "unsafe permissions for %s", resolved); + return NULL; } xasprintf(&path, "%s/%s", resolved, label); return (path); Best regards Uwe
