Subject: hurd hurdstartup: Initialize remaining fields of hurd_startup_data
X-Git-Tag: glibc-2.37~55
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f77bd0ee9a4a7ef7295f3a35a0ca67c95c4e1bd6;p=thirdparty%2Fglibc.git

hurd hurdstartup: Initialize remaining fields of hurd_startup_data

In case we don't have a bootstrap port or __exec_startup_get_info
failed, we should avoid leaking uninitialized fields of data.
