2020-07-24scripts/decode_stacktrace: strip basepath from all pathsPi-Hsun Shih1-2/+2
Currently the basepath is removed only from the beginning of the string. When the symbol is inlined and there's multiple line outputs of addr2line, only the first line would have basepath removed. Change to remove the basepath prefix from all lines.

2020-07-24squashfs: fix length field overlap check in metadata readingPhillip Lougher1-1/+1
This is a regression introduced by the "migrate from ll_rw_block usage to BIO" patch. Squashfs packs structures on byte boundaries, and due to that the length field (of the metadata block) may not be fully in the current block. The new code rewrote and introduced a faulty check for that edge case.

2020-07-24khugepaged: fix null-pointer dereference due to raceKirill A. Shutemov1-0/+3
khugepaged has to drop mmap lock several times while collapsing a page. The situation can change while the lock is dropped and we need to re-validate that the VMA is still in place and the PMD is still subject for collapse. But we miss one corner case: while collapsing an anonymous pages the VMA could be replaced with file VMA. If the file VMA doesn't have any private pages we get NULL pointer dereference: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] anon_vma_lock_write include/linux/rmap.h:120 [inline] collapse_huge_page mm/khugepaged.c:1110 [inline] khugepaged_scan_pmd mm/khugepaged.c:1349 [inline] khugepaged_scan_mm_slot mm/khugepaged.c:2110 [inline] khugepaged_do_scan mm/khugepaged.c:2193 [inline] khugepaged+0x3bba/0x5a10 mm/khugepaged.c:2238 The fix is to make sure that the VMA is anonymous in hugepage_vma_revalidate().

2020-07-24mm: memcg/slab: fix memory leak at non-root kmem_cache destroyMuchun Song1-7/+28
If the kmem_cache refcount is greater than one, we should not mark the root kmem_cache as dying. If we mark the root kmem_cache dying incorrectly, the non-root kmem_cache can never be destroyed. It resulted in memory leak when memcg was destroyed. We can use the following steps to reproduce. 1) Use kmem_cache_create() to create a new kmem_cache named A. 2) Coincidentally, the kmem_cache A is an alias for kmem_cache B, so the refcount of B is just increased. 3) Use kmem_cache_destroy() to destroy the kmem_cache A, just decrease the B's refcount but mark the B as dying. 4) Create a new memory cgroup and alloc memory from the kmem_cache B. It leads to create a non-root kmem_cache for allocating memory. 5) When destroy the memory cgroup created in the step 4), the non-root kmem_cache can never be destroyed. If we repeat steps 4) and 5), this will cause a lot of memory leak. So only when refcount reach zero, we mark the root kmem_cache as dying.

2020-07-24mm/memcg: fix refcount error while moving and swappingHugh Dickins1-2/+2
It was hard to keep a test running, moving tasks between memcgs with move_charge_at_immigrate, while swapping: mem_cgroup_id_get_many()'s refcount is discovered to be 0 (supposedly impossible), so it is then forced to REFCOUNT_SATURATED, and after thousands of warnings in quick succession, the test is at last put out of misery by being OOM killed. This is because of the way moved_swap accounting was saved up until the task move gets completed in __mem_cgroup_clear_mc(), deferred from when mem_cgroup_move_swap_account() actually exchanged old and new ids. Concurrent activity can free up swap quicker than the task is scanned, bringing id refcount down 0 (which should only be possible when offlining). Just skip that optimization: do that part of the accounting immediately.

2020-07-24mm/memcontrol: fix OOPS inside mem_cgroup_get_nr_swap_pages()Bhupesh Sharma1-1/+8
Prabhakar reported an OOPS inside mem_cgroup_get_nr_swap_pages() function in a corner case seen on some arm64 boards when kdump kernel runs with "cgroup_disable=memory" passed to the kdump kernel via bootargs. The root-cause behind the same is that currently mem_cgroup_swap_init() function is implemented as a subsys_initcall() call instead of a core_initcall(), this means 'cgroup_memory_noswap' still remains set to the default value (false) even when memcg is disabled via "cgroup_disable=memory" boot parameter.

2020-07-24mm/mmap.c: close race between munmap() and expand_upwards()/downwards()Kirill A. Shutemov1-2/+14
VMA with VM_GROWSDOWN or VM_GROWSUP flag set can change their size under mmap_read_lock(). It can lead to race with __do_munmap(): Thread A Thread B __do_munmap() detach_vmas_to_be_unmapped() mmap_write_downgrade() expand_downwards() vma->vm_start = address; // The VMA now overlaps with // VMAs detached by the Thread A // page fault populates expanded part // of the VMA unmap_region() // Zaps pagetables partly // populated by Thread B Similar race exists for expand_upwards(). The fix is to avoid downgrading mmap_lock in __do_munmap() if detached VMAs are next to VM_GROWSDOWN or VM_GROWSUP VMA.

As a consequence base->clk can be set back as well. This can lead to timers expiring early. Add a sanity check to prevent this. - When a timer is queued with an expiry time beyond the wheel capacity then it should be queued in the bucket of the last wheel level which is expiring last. The code adjusted the expiry time to the maximum wheel capacity, which is only correct when the wheel clock is 0. Aside of that the check whether the delta is larger than wheel capacity does not check the delta, it checks the expiry value itself. As a result timers can expire at random. Fix this by checking the right variable and adjust expiry time so it becomes base->clock plus capacity which places it into the outmost bucket in the last wheel level" * tag 'timers-urgent-2020-07-19' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: timer: Fix wheel index calculation on last level timer: Prevent base->clk from moving backward

The core code stores a pointer to it which can lead to a use after free or double free. This used to "work" because the pointer was not stored when the initial code was written, but at some point later it was required to store it. Of course nobody noticed that the existing users break that way. - Handle affinity setting on inactive interrupts correctly when hierarchical irq domains are enabled. When interrupts are inactive with the modern hierarchical irqdomain design, the interrupt chips are not necessarily in a state where affinity changes can be handled. The legacy irq chip design allowed this because interrupts are immediately fully initialized at allocation time. X86 has a hacky workaround for this, but other implementations do not. This cased malfunction on GIC-V3. Instead of playing whack a mole to find all affected drivers, change the core code to store the requested affinity setting and then establish it when the interrupt is allocated, which makes the X86 hack go away" * tag 'irq-urgent-2020-07-19' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq/affinity: Handle affinity setting on inactive interrupts correctly irqdomain/treewide: Keep firmware node unconditionally allocated

Currently the check on bits 25:24 on ISPSSPM0 is always 0 because the mask and shift operations are incorrect. Fix this by shifting by MRFLD_ISPSSPM0_ISPSSS_OFFSET (24 bits right) and then masking with RFLD_ISPSSPM0_ISPSSC_MASK (0x03) to get the appropriate 2 bits to check.

2020-07-19x86/boot: Don't add the EFI stub to targetsArvind Sankar1-2/+2
vmlinux-objs-y is added to targets, which currently means that the EFI stub gets added to the targets as well. It shouldn't be added since it is built elsewhere. This confuses Makefile.build which interprets the EFI stub as a target $(obj)/$(objtree)/drivers/firmware/efi/libstub/lib.a and will create drivers/firmware/efi/libstub/ underneath arch/x86/boot/compressed, to hold this supposed target, if building out-of-tree.

2020-07-19x86/entry: Actually disable stack protectorKees Cook1-3/+11
Some builds of GCC enable stack protector by default.

2020-07-19media: atomisp: get rid of version-specific system_local.hMauro Carvalho Chehab3-350/+194
After removing the unused 32-bits data, the isp2401_system_local.h now contains everything that it is needed, either by isp2401 or by isp2400. So, remove code duplication. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-07-19media: atomisp: move global stuff into a common headerMauro Carvalho Chehab7-714/+403
Right now, there are two versions of system_global.h headers. Both share a lot of common code. There are some ISP2401 specific types on one of the headers, but it doesn't conflict with the ISP2400 ones. Also, the common code is identical. So, remove code duplication by moving such code into a common header. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-07-19media: atomisp: remove non-used 32-bits consts at system_localMauro Carvalho Chehab5-331/+3
There is an abstraction at the code in order to support 32 or 64 bits address/data length. However, for all Atom chipsets supported by this version, the size is fixed. So, cleanup the mess, removing the uused code and placing the data sizes on a single place. The end goal is to completely remove those local/global headers, replacing them by some ISP-version dependent struct, in order for the driver to decide what version it would need in runtime.

2020-07-18hwmon: (drivetemp) Avoid SCT usage on Toshiba DT01ACA family drivesMaciej S. Szmigiero1-0/+43
It has been observed that Toshiba DT01ACA family drives have WRITE FPDMA QUEUED command timeouts and sometimes just freeze until power-cycled under heavy write loads when their temperature is getting polled in SCT mode. The SMART mode seems to be fine, though. Let's make sure we don't use SCT mode for these drives then. While only the 3 TB model was actually caught exhibiting the problem let's play safe here to avoid data corruption and extend the ban to the whole family.
