Descriptions

In the Linux kernel, the following vulnerability has been resolved:

lib/Kconfig.debug: TEST_IOV_ITER depends on MMU

Trying to run the iov_iter unit test on a nommu system such as the qemu
kc705-nommu emulation results in a crash.

KTAP version 1
# Subtest: iov_iter
# module: kunit_iov_iter
1..9
BUG: failure at mm/nommu.c:318/vmap()!
Kernel panic - not syncing: BUG!

The test calls vmap() directly, but vmap() is not supported on nommu
systems, causing the crash. TEST_IOV_ITER therefore needs to depend on
MMU.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: lib/Kconfig.debug: TEST_IOV_ITER depende de MMU Intentar ejecutar la prueba unitaria iov_iter en un sistema nommu como la emulación qemu kc705-nommu produce un bloqueo. KTAP versión 1 # Subprueba: iov_iter # módulo: kunit_iov_iter 1..9 BUG: fallo en mm/nommu.c:318/vmap()! Pánico del kernel: no se sincroniza: ¡BUG! La prueba llama a vmap() directamente, pero vmap() no es compatible con los sistemas nommu, lo que provoca el bloqueo. Por lo tanto, TEST_IOV_ITER debe depender de MMU.
