And many other small improvements & fixes. There's a few out-of-area changes. Some minor ftrace changes OK'ed by Steve, and a fix to our powernv cpuidle driver. Then there's a series touching mm, x86 and fs/proc/task_mmu.c, which cleans up some details around pkey support. It was ack'ed/reviewed by Ingo & Dave and has been in next for several weeks.

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull overflow updates from Kees Cook: "This adds the new overflow checking helpers and adds them to the 2-factor argument allocators. And this adds the saturating size helpers and does a treewide replacement for the struct_size() usage. Additionally this adds the overflow testing modules to make sure everything works. I'm still working on the treewide replacements for allocators with "simple" multiplied arguments: *alloc(a * b, ...) -> *alloc_array(a, b, ...) and *zalloc(a * b, ...) -> *calloc(a, b, ...) as well as the more complex cases, but that's separable from this portion of the series. I expect to have the rest sent before -rc1 closes; there are a lot of messy cases to clean up. Summary: - Introduce arithmetic overflow test helper functions (Rasmus) - Use overflow helpers in 2-factor allocators (Kees, Rasmus) - Introduce overflow test module (Rasmus, Kees) - Introduce saturating size helper functions (Matthew, Kees) - Treewide use of struct_size() for allocators (Kees)" * tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: treewide: Use struct_size() for devm_kmalloc() and friends treewide: Use struct_size() for vmalloc()-family treewide: Use struct_size() for kmalloc()-family device: Use overflow helpers for devm_kmalloc() mm: Use overflow helpers in kvmalloc() mm: Use overflow helpers in kmalloc_array*() test_overflow: Add memory allocation overflow tests overflow.h: Add allocation size calculation helpers test_overflow: Report test failures test_overflow: macrofy some more, do more tests for free lib: add runtime test of check_*_overflow functions compiler.h: enable builtin overflow checkers and add fallback code

2018-06-06treewide: Use struct_size() for kmalloc()-familyKees Cook43-96/+75
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL); This patch makes the changes for kmalloc()-family (and kvmalloc()-family) uses. It was done via automatic conversion with manual review for the "CHECKME" non-standard cases noted below, using the following Coccinelle script: // pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len * // sizeof *pkey_cache->table, GFP_KERNEL); @@ identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc"; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(sizeof(*VAR) + COUNT * sizeof(*VAR->ELEMENT), GFP) + alloc(struct_size(VAR, ELEMENT, COUNT), GFP) // mr = kzalloc(sizeof(*mr) + m * sizeof(mr->map[0]), GFP_KERNEL); @@ identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc"; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(sizeof(*VAR) + COUNT * sizeof(VAR->ELEMENT[0]), GFP) + alloc(struct_size(VAR, ELEMENT, COUNT), GFP) // Same pattern, but can't trivially locate the trailing element name, // or variable name. @@ identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc"; expression GFP; expression SOMETHING, COUNT, ELEMENT; @@ - alloc(sizeof(SOMETHING) + COUNT * sizeof(ELEMENT), GFP) + alloc(CHECKME_struct_size(&SOMETHING, ELEMENT, COUNT), GFP) Signed-off-by: Kees Cook <keescook@chromium.org>

When the PF frequently switches the CMDQ interrupt, if the CMDQ_SRC is not cleared before the hardware interrupt is generated, the new interrupt will not be reported.

In the Broadcom Cygnus SoC, the brcm tag needs to be inserted in between the mac address and the ether type (should use 'DSA_PROTO_TAG_BRCM') for the packets sent to the internal b53 switch. Since the Cygnus was added with the BCM58XX device id and the BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is broken, due to the incorrect brcm tag location. Add a new b53 device id (BCM583XX) for Cygnus family to fix the issue. Add the new device id to the BCM58XX family as Cygnus is similar to the BCM58XX in most other functionalities.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata Pull libata updates from Tejun Heo: - libata has always been limiting the maximum queue depth to 31, with one entry set aside mostly for historical reasons. This didn't use to make much difference but Jens found out that modern hard drives can actually perform measurably better with the extra one queue depth. Jens updated libata core so that it can make use of full 32 queue depth - Damien updated command retry logic in error handling so that it doesn't unnecessarily retry when upper layer (SCSI) is gonna handle them - A couple misc changes * 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: sata_fsl: use the right type for tag bitshift ahci: enable full queue depth of 32 libata: don't clamp queue depth to ATA_MAX_QUEUE - 1 libata: add extra internal command sata_nv: set host can_queue count appropriately libata: remove assumption that ATA_MAX_QUEUE - 1 is the max libata: use ata_tag_internal() consistently libata: bump ->qc_active to a 64-bit type libata: convert core and drivers to ->hw_tag usage libata: introduce notion of separate hardware tags libata: Fix command retry decision libata: Honor RQF_QUIET flag libata: Make ata_dev_set_mode() less verbose libata: Fix ata_err_string() libata: Fix comment typo in ata_eh_analyze_tf() sata_nv: don't use block layer bounce buffer ata: hpt37x: Convert to use match_string() helper
