Subject: [PATCH v2 0/4] riscv: modules: Fix module loading error handling
Date: Wed, 03 Jan 2024 12:21:59 -0800 [thread overview]
Message-ID: <20240103-module_loading_fix-v2-0-292b160552c9@rivosinc.com> (raw)
When modules are loaded while there is not ample allocatable memory,
there was previously not proper error handling. This series fixes a
use-after-free error and a different issue that caused a non graceful
exit after memory was not properly allocated.
