Elixir Cross Referencer - source code of U-boot v2024.10: include/malloc.h

In the kernel, malloc() is not available. Instead, the kernel has to define its own memory allocation functions. However, many different allocation mechanisms exist.

January 7, 2025 - Another limitation of syzkaller is its inability to use malloc() for dynamic memory allocation, complicating the implementation of authentication in pseudo syscalls. To work around this, we patched the relevant authentication (NTLMv2) and packet signature verification checks, allowing us to ...

In the context of the partnership between Bootlin, the eBPF Foundation and the Alpha Omega organization, Bootlin engineer Alexis Lothoré is currently working on adding KASAN memory checker support to the eBPF subsystem: this work aims to make it easier for eBPF subsystem developers to catch (early) bugs that could be introduced in complex parts of the kernel, like in the eBPF verifier.
