From 11158aef8939bb6e54361e4dae3809a9cbe78cff Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 26 Jul 2023 21:01:25 -0600 Subject: [PATCH] bootstd: Init the size before reading extlinux file The implementation in extlinux_pxe_getfile() does not pass a valid size to bootmeth_read_file(), so this can fail if the uninited value happens to be too small. Fix this.
