From 825a9a94e1a5795e545156ead664a85403cda0e1 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Wed, 12 May 2021 18:38:51 +0200 Subject: sandbox: fix sandbox_reset() state_uninit() and dm_uninit() are mutually exclusive: state_uninit() prints via drivers. So it cannot be executed after dm_uninit(). dm_uninit() requires memory. So it cannot be executed after state_uninit() which releases all memory. Just skip dm_uninit() when resetting the sandbox. We will wake up in a new process and allocate new memory. So this cleanup is not required. We don't do it in sandbox_exit() either. This avoids a segmentation error when efi_reset_system_boottime() is invoked by a UEFI application.
