[PATCH kernel-4.19 18/19] init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM
by Yang Yingliang 15 Apr '21

15 Apr '21

From: Masahiro Yamada <masahiroy(a)kernel.org> commit ea29b20a828511de3348334e529a3d046a180416 upstream. I read the commit log of the following two: - bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML") - 334ef6ed06fa ("init/Kconfig: make COMPILE_TEST depend on !S390") Both are talking about HAS_IOMEM dependency missing in many drivers. So, 'depends on HAS_IOMEM' seems the direct, sensible solution to me. This does not change the behavior of UML. UML still cannot enable COMPILE_TEST because it does not provide HAS_IOMEM. The current dependency for S390 is too strong. Under the condition of CONFIG_PCI=y, S390 provides HAS_IOMEM, hence can enable COMPILE_TEST. I also removed the meaningless 'default n'.

[PATCH kernel-4.19 17/19] init/Kconfig: make COMPILE_TEST depend on !S390
by Yang Yingliang 15 Apr '21

15 Apr '21

From: Heiko Carstens <hca(a)linux.ibm.com> commit 334ef6ed06fa1a54e35296b77b693bcf6d63ee9e upstream. While allmodconfig and allyesconfig build for s390 there are also various bots running compile tests with randconfig, where PCI is disabled. This reveals that a lot of drivers should actually depend on HAS_IOMEM. Adding this to each device driver would be a never ending story, therefore just disable COMPILE_TEST for s390. The reasoning is more or less the same as described in commit bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML").

[PATCH kernel-4.19 15/19] bpf, x86: Validate computation of branch displacements for x86-64
by Yang Yingliang 15 Apr '21

15 Apr '21

From: Piotr Krysiuk <piotras(a)gmail.com> commit e4d4d456436bfb2fe412ee2cd489f7658449b098 upstream. The branch displacement logic in the BPF JIT compilers for x86 assumes that, for any generated branch instruction, the distance cannot increase between optimization passes. But this assumption can be violated due to how the distances are computed. Specifically, whenever a backward branch is processed in do_jit(), the distance is computed by subtracting the positions in the machine code from different optimization passes. This is because part of addrs[] is already updated for the current optimization pass, before the branch instruction is visited. And so the optimizer can expand blocks of machine code in some cases. This can confuse the optimizer logic, where it assumes that a fixed point has been reached for all machine code blocks once the total program size stops changing. And then the JIT compiler can output abnormal machine code containing incorrect branch displacements. To mitigate this issue, we assert that a fixed point is reached while populating the output image. This rejects any problematic programs. The issue affects both x86-32 and x86-64. We mitigate separately to ease backporting.
