git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull overflow updates from Kees Cook: "The end goal of the current buffer overflow detection work[0] is to gain full compile-time and run-time coverage of all detectable buffer overflows seen via array indexing or memcpy(), memmove(), and memset(). The str*() family of functions already have full coverage. While much of the work for these changes have been on-going for many releases (i.e. 0-element and 1-element array replacements, as well as avoiding false positives and fixing discovered overflows[1]), this series contains the foundational elements of several related buffer overflow detection improvements by providing new common helpers and FORTIFY_SOURCE changes needed to gain the introspection required for compiler visibility into array sizes. Also included are a handful of already Acked instances using the helpers (or related clean-ups), with many more waiting at the ready to be taken via subsystem-specific trees[2]. The new helpers are: - struct_group() for gaining struct member range introspection - memset_after() and memset_startat() for clearing to the end of structures - DECLARE_FLEX_ARRAY() for using flex arrays in unions or alone in structs Also included is the beginning of the refactoring of FORTIFY_SOURCE to support memcpy() introspection, fix missing and regressed coverage under GCC, and to prepare to fix the currently broken Clang support. Finishing this work is part of the larger series[0], but depends on all the false positives and buffer overflow bug fixes to have landed already and those that depend on this series to land. As part of the FORTIFY_SOURCE refactoring, a set of both a compile-time and run-time tests are added for FORTIFY_SOURCE and the mem*()-family functions respectively. The compile time tests have found a legitimate (though corner-case) bug[6] already. Please note that the appearance of "panic" and "BUG" in the FORTIFY_SOURCE refactoring are the result of relocating existing code, and no new use of those code-paths are expected nor desired. Finally, there are two tree-wide conversions for 0-element arrays and flexible array unions to gain sane compiler introspection coverage that result in no known object code differences. After this series (and the changes that have now landed via netdev and usb), we are very close to finally being able to build with -Warray-bounds and -Wzero-length-bounds. However, due corner cases in GCC[3] and Clang[4], I have not included the last two patches that turn on these options, as I don't want to introduce any known warnings to the build. Hopefully these can be solved soon" Link: https://lore.kernel.org/lkml/20210818060533.3569517-1-keescook@chromium.org/ [0] Link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?qt=grep&q=FORTIFY_SOURCE [1] Link: https://lore.kernel.org/lkml/202108220107.3E26FE6C9C@keescook/ [2] Link: https://lore.kernel.org/lkml/3ab153ec-2798-da4c-f7b1-81b0ac8b0c5b@roeck-us.net/ [3] Link: https://bugs.llvm.org/show_bug.cgi?id=51682 [4] Link: https://lore.kernel.org/lkml/202109051257.29B29745C0@keescook/ [5] Link: https://lore.kernel.org/lkml/20211020200039.170424-1-keescook@chromium.org/ [6] * tag 'overflow-v5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (30 commits) fortify: strlen: Avoid shadowing previous locals compiler-gcc.h: Define __SANITIZE_ADDRESS__ under hwaddress sanitizer treewide: Replace 0-element memcpy() destinations with flexible arrays treewide: Replace open-coded flex arrays in unions stddef: Introduce DECLARE_FLEX_ARRAY() helper btrfs: Use memset_startat() to clear end of struct string.h: Introduce memset_startat() for wiping trailing members and padding xfrm: Use memset_after() to clear padding string.h: Introduce memset_after() for wiping trailing members/padding lib: Introduce CONFIG_MEMCPY_KUNIT_TEST fortify: Add compile-time FORTIFY_SOURCE tests fortify: Allow strlen() and strnlen() to pass compile-time known lengths fortify: Prepare to improve strnlen() and strlen() warnings fortify: Fix dropped strcpy() compile-time write overflow check fortify: Explicitly disable Clang support fortify: Move remaining fortify helpers into fortify-string.h lib/string: Move helper functions out of string.c compiler_types.h: Remove __compiletime_object_size() cm4000_cs: Use struct_group() to zero struct cm4000_dev region can: flexcan: Use struct_group() to zero struct flexcan_regs regions ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "There's the usual summary below, but the highlights are support for the Armv8.6 timer extensions, KASAN support for asymmetric MTE, the ability to kexec() with the MMU enabled and a second attempt at switching to the generic pfn_valid() implementation. Summary: - Support for the Arm8.6 timer extensions, including a self-synchronising view of the system registers to elide some expensive ISB instructions. - Exception table cleanup and rework so that the fixup handlers appear correctly in backtraces. - A handful of miscellaneous changes, the main one being selection of CONFIG_HAVE_POSIX_CPU_TIMERS_TASK_WORK. - More mm and pgtable cleanups. - KASAN support for "asymmetric" MTE, where tag faults are reported synchronously for loads (via an exception) and asynchronously for stores (via a register). - Support for leaving the MMU enabled during kexec relocation, which significantly speeds up the operation. - Minor improvements to our perf PMU drivers. - Improvements to the compat vDSO build system, particularly when building with LLVM=1. - Preparatory work for handling some Coresight TRBE tracing errata. - Cleanup and refactoring of the SVE code to pave the way for SME support in future. - Ensure SCS pages are unpoisoned immediately prior to freeing them when KASAN is enabled for the vmalloc area. - Try moving to the generic pfn_valid() implementation again now that the DMA mapping issue from last time has been resolved. - Numerous improvements and additions to our FPSIMD and SVE selftests" [ armv8.6 timer updates were in a shared branch and already came in through -tip in the timer pull - Linus ] * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (85 commits) arm64: Select POSIX_CPU_TIMERS_TASK_WORK arm64: Document boot requirements for FEAT_SME_FA64 arm64/sve: Fix warnings when SVE is disabled arm64/sve: Add stub for sve_max_virtualisable_vl() arm64: errata: Add detection for TRBE write to out-of-range arm64: errata: Add workaround for TSB flush failures arm64: errata: Add detection for TRBE overwrite in FILL mode arm64: Add Neoverse-N2, Cortex-A710 CPU part definition selftests: arm64: Factor out utility functions for assembly FP tests arm64: vmlinux.lds.S: remove `.fixup` section arm64: extable: add load_unaligned_zeropad() handler arm64: extable: add a dedicated uaccess handler arm64: extable: add `type` and `data` fields arm64: extable: use `ex` for `exception_table_entry` arm64: extable: make fixup_exception() return bool arm64: extable: consolidate definitions arm64: gpr-num: support W registers arm64: factor out GPR numbering helpers arm64: kvm: use kvm_exception_table_entry arm64: lib: __arch_copy_to_user(): fold fixups into body ...

2021-11-01firewire: Remove function callback castsOscar Carter1-6/+26
In 1394 OHCI specification, Isochronous Receive DMA context has several modes. One of mode is 'BufferFill' and Linux FireWire stack uses it to receive isochronous packets for multiple isochronous channel as FW_ISO_CONTEXT_RECEIVE_MULTICHANNEL. The mode is not used by in-kernel driver, while it's available for userspace. The character device driver in firewire-core includes cast of function callback for the mode since the type of callback function is different from the other modes. The case is inconvenient to effort of Control Flow Integrity builds due to -Wcast-function-type warning. This commit removes the cast. A static helper function is newly added to initialize isochronous context for the mode. The helper function arranges isochronous context to assign specific callback function after call of existent kernel API. It's noticeable that the number of isochronous channel, speed, and the size of header are not required for the mode. The helper function is used for the mode by character device driver instead of direct call of existent kernel API. The same goal can be achieved (in the ioctl_create_iso_context function) without this helper function as follows: - Call the fw_iso_context_create function passing NULL to the callback parameter. - Then setting the context->callback.sc or context->callback.mc variables based on the a->type value. However using the helper function created in this patch makes code more clear and declarative. This way avoid the call to a function with one purpose to achieved another one.

2021-10-30scsi: ufs: ufshpb: Remove HPB2.0 flowsAvri Altman3-288/+4
The Host Performance Buffer feature allows UFS read commands to carry the physical media addresses along with the LBAs, thus allowing less internal L2P-table switches in the device. HPB1.0 allowed a single LBA, while HPB2.0 increases this capacity up to 255 blocks. Carrying more than a single record, the read operation is no longer purely of type "read" but a "hybrid" command: Writing the physical address to the device in one operation and reading back the required payload in another. The JEDEC HPB spec defines two commands for this operation: HPB-WRITE-BUFFER (0x2) to write the physical addresses to device, and HPB-READ to read the payload. With the current HPB design the UFS driver has no alternative but to divide the READ request into 2 separate commands: HPB-WRITE-BUFFER and HPB-READ. This causes a great deal of aggravation to the block layer guys who demanded that we completely revert the entire HPB driver regardless of the huge amount of corporate effort already invested in it. As a compromise, remove only the pieces that implement the 2.0 specification. This is done as a matter of urgency for the final 5.15 release.

Testing revealed a problem with how the reference tag was handled for a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when the controller is asked to generate the protection information (i.e. not DIX). And as a result the initial reference tag would not be set in the WRITE_INSERT case. Separate handling of the REF_CHECK and REF_INCREMENT flags to align with both the DIX spec and the MPI implementation.

2021-10-29null_blk: Fix handling of submit_queues and poll_queues attributesShin'ichiro Kawasaki2-17/+87
Commit 0a593fbbc245 ("null_blk: poll queue support") introduced the poll queue feature to null_blk. After this change, null_blk device has both submit queues and poll queues, and null_map_queues() callback maps the both queues for corresponding hardware contexts. The commit also added the device configuration attribute 'poll_queues' in same manner as the existing attribute 'submit_queues'. These attributes allow to modify the numbers of queues. However, when the new values are stored to these attributes, the values are just handled only for the corresponding queue. When number of submit_queue is updated, number of poll_queue is not counted, or vice versa. This caused inconsistent number of queues and queue mapping and resulted in null-ptr-dereference. This failure was observed in blktests block/029 and block/030. To avoid the inconsistency, fix the attribute updates to care both submit_queues and poll_queues. Introduce the helper function nullb_update_nr_hw_queues() to handle stores to the both two attributes. Add poll_queues field to the struct nullb_device to track the number in same manner as submit_queues. Add two more fields prev_submit_queues and prev_poll_queues to keep the previous values before change. In case the block layer failed to update the nr_hw_queues, refer the previous values in null_map_queues() to map queues in same manner as before change. Also add poll_queues value checks in nullb_update_nr_hw_queues() and null_validate_conf(). They ensure the poll_queues value of each device is within the range from 1 to module parameter value of poll_queues.

This reverts commit 3bda2e5df476417b6d08967e2d84234a59d57b1c. According to discussion with Andrew as follow: https://lore.kernel.org/netdev/09eda9fe-196b-006b-6f01-f54e75715961@huawei.com/ HNS3 driver needs to separate pause autoneg from general autoneg, so revert this incorrect patch.

2021-10-28octeontx2-af: Display all enabled PF VF rsrc_alloc entries.Rakesh Babu1-32/+106
Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size.

2021-10-28net: ethernet: microchip: lan743x: Fix skb allocation failureYuiko Oshino1-4/+9
The driver allocates skb during ndo_open with GFP_ATOMIC which has high chance of failure when there are multiple instances. GFP_KERNEL is enough while open and use GFP_ATOMIC only from interrupt context.
