| * mm, kasan: stackdepot implementation. Enable stackdepot for SLABAlexander Potapenko2016-03-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the stack depot and provide CONFIG_STACKDEPOT. Stack depot will allow KASAN store allocation/deallocation stack traces for memory chunks. The stack traces are stored in a hash table and referenced by handles which reside in the kasan_alloc_meta and kasan_free_meta structures in the allocated memory chunks. IRQ stack traces are cut below the IRQ entry point to avoid unnecessary duplication. Right now stackdepot support is only enabled in SLAB allocator. Once KASAN features in SLAB are on par with those in SLUB we can switch SLUB to stackdepot as well, thus removing the dependency on SLUB stack bookkeeping, which wastes a lot of memory. This patch is based on the "mm: kasan: stack depots" patch originally prepared by Dmitry Chernenkov. Joonsoo has said that he plans to reuse the stackdepot code for the mm/page_owner.c debugging facility.

| * arch, ftrace: for KASAN put hard/soft IRQ entries into separate sectionsAlexander Potapenko2016-03-2518-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | KASAN needs to know whether the allocation happens in an IRQ handler. This lets us strip everything below the IRQ entry point to reduce the number of unique stack traces needed to be stored. Move the definition of __irq_entry to <linux/interrupt.h> so that the users don't need to pull in <linux/ftrace.h>. Also introduce the __softirq_entry macro which is similar to __irq_entry, but puts the corresponding functions to the .softirqentry.text section.

This was necessary for older cores without broadcast data cache maintenance, and ensured that cache lines were dirtied and cleaned by the same CPU. On these systems dirty cache line migration was not possible, so this was sufficient to guarantee coherency. On contemporary systems, cache coherence protocols permit (dirty) cache lines to migrate between CPUs as a result of speculation, prefetching, and other behaviours. To account for this, in ARMv8 data cache maintenance operations are broadcast and affect all data caches in the domain associated with the VA (i.e. ISH for kernel and user mappings). In __switch_to we ensure that tasks can be safely migrated in the middle of a maintenance sequence, using a dsb(ish) to ensure prior explicit memory accesses are observed and cache maintenance operations are completed before a task can be run on another CPU. Given the above, it is not necessary to disable preemption in copy_to_user_page. This patch removes the preempt_{disable,enable} calls, permitting preemption.

These differ from open-coded huge page creation in the early page table code by explicitly setting the P?D_TYPE_SECT bits (which are implicitly retained by mk_sect_prot() for any valid prot), but are otherwise identical (and cannot fail on arm64). For simplicity and consistency, make use of these in the initial page table creation code.

If the MMU needs to be disabled again to create the randomized kernel mapping, x18 is written back to SCTLR_EL1, which is likely to crash the system if x18 has been clobbered by kasan_early_init() or kaslr_early_init().

Since commit 8ec41987436d566f ("arm64: mm: ensure patched kernel text is fetched from PoU"), all CPUs invalidate their I-caches after their MMU is enabled. Prior a CPU's MMU having been enabled, arbitrary lines may have been fetched from the PoC into I-caches. We never patch text expected to be executed with the MMU off. Thus, it is unnecessary to perform broadcast I-cache maintenance in the primary boot path. This patch reduces the scope of the I-cache maintenance to the local CPU, and adds the missing DSB with similar scope, matching prior maintenance in the primary boot path.
