2022-08-17f2fs: revive F2FS_IOC_ABORT_VOLATILE_WRITEDaeho Jeong
commit 23339e5752d01a4b5e122759b002cf896d26f6c1 upstream. F2FS_IOC_ABORT_VOLATILE_WRITE was used to abort a atomic write before. However it was removed accidentally. So revive it by changing the name, since volatile write had gone.

2022-08-17can: error: specify the values of data[5..7] of CAN error framesVincent Mailhol
[ Upstream commit e70a3263a7eed768d5f947b8f2aff8d2a79c9d97 ] Currently, data[5..7] of struct can_frame, when used as a CAN error frame, are defined as being "controller specific". Device specific behaviours are problematic because it prevents someone from writing code which is portable between devices. As a matter of fact, data[5] is never used, data[6] is always used to report TX error counter and data[7] is always used to report RX error counter. can-utils also relies on this. This patch updates the comment in the uapi header to specify that data[5] is reserved (and thus should not be used) and that data[6..7] are used for error counters.

2022-08-17bpf: Allow storing referenced kptr in mapKumar Kartikeya Dwivedi
[ Upstream commit c0a5a21c25f37c9fd7b36072f9968cdff1e4aa13 ] Extending the code in previous commits, introduce referenced kptr support, which needs to be tagged using 'kptr_ref' tag instead. Unlike unreferenced kptr, referenced kptr have a lot more restrictions. In addition to the type matching, only a newly introduced bpf_kptr_xchg helper is allowed to modify the map value at that offset. This transfers the referenced pointer being stored into the map, releasing the references state for the program, and returning the old value and creating new reference state for the returned pointer. Similar to unreferenced pointer case, return value for this case will also be PTR_TO_BTF_ID_OR_NULL. The reference for the returned pointer must either be eventually released by calling the corresponding release function, otherwise it must be transferred into another map. It is also allowed to call bpf_kptr_xchg with a NULL pointer, to clear the value, and obtain the old value if any. BPF_LDX, BPF_STX, and BPF_ST cannot access referenced kptr. A future commit will permit using BPF_LDX for such pointers, but attempt at making it safe, since the lifetime of object won't be guaranteed. There are valid reasons to enforce the restriction of permitting only bpf_kptr_xchg to operate on referenced kptr. The pointer value must be consistent in face of concurrent modification, and any prior values contained in the map must also be released before a new one is moved into the map. To ensure proper transfer of this ownership, bpf_kptr_xchg returns the old value, which the verifier would require the user to either free or move into another map, and releases the reference held for the pointer being moved in. In the future, direct BPF_XCHG instruction may also be permitted to work like bpf_kptr_xchg helper. Note that process_kptr_func doesn't have to call check_helper_mem_access, since we already disallow rdonly/wronly flags for map, which is what check_map_access_type checks, and we already ensure the PTR_TO_MAP_VALUE refers to kptr by obtaining its off_desc, so check_map_access is also not required.

commit 8cc5b032240ae5220b62c689c20459d3e1825b2d upstream. The {pid,uid}_t fields of struct binder_transaction were recently replaced to use kernel types in commit 169adc2b6b3c ("android/binder.h: add linux/android/binder(fs).h to UAPI compile-test coverage"). However, using __kernel_uid_t here breaks backwards compatibility in architectures using 16-bits for this type, since glibc and some others still expect a 32-bit uid_t. Instead, let's use __kernel_uid32_t which avoids this compatibility problem.

2022-06-09linux/types.h: reinstate "__bitwise__" macro for user space useLinus Torvalds
[ Upstream commit caa28984163cb63ea0be4cb8dbf05defdc7303f9 ] Commit c724c866bb70 ("linux/types.h: remove unnecessary __bitwise__") was right that there are no users of __bitwise__ in the kernel, but it turns out there are user space users of it that do expect it.

Instead of reverting the commit completely, let's just clarify the situation so that it doesn't happen again, and have some in-code explanations for why that "__bitwise__" still exists.

2022-04-29KVM: fix bad user ABI for KVM_EXIT_SYSTEM_EVENTPaolo Bonzini
When KVM_EXIT_SYSTEM_EVENT was introduced, it included a flags member that at the time was unused. Unfortunately this extensibility mechanism has several issues: - x86 is not writing the member, so it would not be possible to use it on x86 except for new events - the member is not aligned to 64 bits, so the definition of the uAPI struct is incorrect for 32- on 64-bit userspace. This is a problem for RISC-V, which supports CONFIG_KVM_COMPAT, but fortunately usage of flags was only introduced in 5.18. Since padding has to be introduced, place a new field in there that tells if the flags field is valid. To allow further extensibility, in fact, change flags to an array of 16 values, and store how many of the values are valid. The availability of the new ndata field is tied to a system capability; all architectures are changed to fill in the field. To avoid breaking compilation of userspace that was using the flags field, provide a userspace-only union to overlap flags with data[0]. The new field is placed at the same offset for both 32- and 64-bit userspace.

2022-04-28elf: Fix the arm64 MTE ELF segment name and valueCatalin Marinas
Unfortunately, the name/value choice for the MTE ELF segment type (PT_ARM_MEMTAG_MTE) was pretty poor: LOPROC+1 is already in use by PT_AARCH64_UNWIND, as defined in the AArch64 ELF ABI (https://github.com/ARM-software/abi-aa/blob/main/aaelf64/aaelf64.rst). Update the ELF segment type value to LOPROC+2 and also change the define to PT_AARCH64_MEMTAG_MTE to match the AArch64 ELF ABI namespace. The AArch64 ELF ABI document is updating accordingly (segment type not previously mentioned in the document).

2022-04-02tracing: mark user_events as BROKENSteven Rostedt (Google)
After being merged, user_events become more visible to a wider audience that have concerns with the current API. It is too late to fix this for this release, but instead of a full revert, just mark it as BROKEN (which prevents it from being selected in make config). Then we can work finding a better API. If that fails, then it will need to be completely reverted. To not have the code silently bitrot, still allow building it with COMPILE_TEST. And to prevent the uapi header from being installed, then later changed, and then have an old distro user space see the old version, move the header file out of the uapi directory. Surround the include with CONFIG_COMPILE_TEST to the current location, but when the BROKEN tag is taken off, it will use the uapi directory, and fail to compile. This is a good way to remind us to move the header back.

2022-03-30loop: fix ioctl calls using compat_loop_infoCarlos Llamas
Support for cryptoloop was deleted in commit 47e9624616c8 ("block: remove support for cryptoloop and the xor transfer"), making the usage of loop_info->lo_encrypt_type obsolete. However, this member was also removed from the compat_loop_info definition and this breaks userspace ioctl calls for 32-bit binaries and CONFIG_COMPAT=y. This patch restores the compat_loop_info->lo_encrypt_type member and marks it obsolete as well as in the uapi header definitions.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Significant refactoring and fixing of how DM core does bio-based IO accounting with focus on fixing wildly inaccurate IO stats for dm-crypt (and other DM targets that defer bio submission in their own workqueues). End result is proper IO accounting, made possible by targets being updated to use the new dm_submit_bio_remap() interface. - Add hipri bio polling support (REQ_POLLED) to bio-based DM. - Reduce dm_io and dm_target_io structs so that a single dm_io (which contains dm_target_io and first clone bio) weighs in at 256 bytes. For reference the bio struct is 128 bytes. - Various other small cleanups, fixes or improvements in DM core and targets. - Update MAINTAINERS with my kernel.org email address to allow distinction between my "upstream" and "Red" Hats. * tag 'for-5.18/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (46 commits) dm: consolidate spinlocks in dm_io struct dm: reduce size of dm_io and dm_target_io structs dm: switch dm_target_io booleans over to proper flags dm: switch dm_io booleans over to proper flags dm: update email address in MAINTAINERS dm: return void from __send_empty_flush dm: factor out dm_io_complete dm cache: use dm_submit_bio_remap dm: simplify dm_sumbit_bio_remap interface dm thin: use dm_submit_bio_remap dm: add WARN_ON_ONCE to dm_submit_bio_remap dm: support bio polling block: add ->poll_bio to block_device_operations dm mpath: use DMINFO instead of printk with KERN_INFO dm: stop using bdevname dm-zoned: remove the ->name field in struct dmz_dev dm: remove unnecessary local variables in __bind dm: requeue IO if mapping table not yet available dm io: remove stale comment block for dm_io() dm thin metadata: remove unused dm_thin_remove_block and __remove ...
