[PATCH] selftests: make use of GUP_TEST_FILE macro

by Joel Savitz

Commit 17de1e559cf1 ("selftests: clarify common error when running gup_test") had most of its hunks dropped due to a conflict with another patch accepted into Linux around the same time that implemented the same behavior as a subset of other changes. However, the remaining hunk defines the GUP_TEST_FILE macro without making use of it. This patch makes use of the macro in the two relevant places. Furthermore, the above mentioned commit's log message erroneously describes the changes that were dropped from the patch. This patch corrects the record.

[RFC PATCH 0/6] User pkey minor bug fixes

by ira.weiny＠intel.com

From: Ira Weiny <ira.weiny(a)intel.com> While evaluating the possibility of defining a new type for pkeys within the kernel I found a couple of minor bugs. Because these patches clean up the return codes from system calls I'm sending this out RFC hoping that users will speak up if anything breaks. I'm not too concerned about pkey_free() because it is unlikely that anyone is checking the return code. Interestingly enough, glibc recommends not calling pkey_free() because it does not change the access rights to the key and may be subsequently allocated again.[1][2] The pkey_alloc() is more concerning. However, I checked the Chrome source and it does not differentiate among the return codes and maps all errors into kNoMemoryProtectionKey. glibc says it returns ENOSYS if the system does not support pkeys but I don't see where ENOSYS is returned? AFAICS it just returns what the kernel returns. So it is probably up to user of glibc. In addition I've enhanced the pkey tests to verify and test the changes. Thanks to Rick Edgecombe and Sohil Mehta for internal review. [1] Quote from manual/memory.texi: Calling this function does not change the access rights of the freed protection key. The calling thread and other threads may retain access to it, even if it is subsequently allocated again. For this reason, it is not recommended to call the @code{pkey_free} function. [2] PKS had a similar issue and went to statically allocated keys instead. Ira Weiny (6): testing/pkeys: Add command line options testing/pkeys: Don't use uninitialized variable testing/pkeys: Add additional test for pkey_alloc() pkeys: Lift pkey hardware check for pkey_alloc() pkeys: Up level pkey_free() checks pkeys: Change mm_pkey_free() to void arch/powerpc/include/asm/pkeys.h | 18 ++--- arch/x86/include/asm/pkeys.h | 7 +- include/linux/pkeys.h | 5 +- mm/mprotect.c | 13 +++- tools/testing/selftests/vm/pkey-helpers.h | 7 +- tools/testing/selftests/vm/protection_keys.c | 75 +++++++++++++++++--- 6 files changed, 86 insertions(+), 39 deletions(-) base-commit: 874c8ca1e60b2c564a48f7e7acc40d328d5c8733 -- 2.35.1

[PATCH v3 0/6] userfaultfd: add /dev/userfaultfd for fine grained access control

by Axel Rasmussen

This series is based on linux-next/akpm-base. The series is split up like so: - Patch 1 is a simple fixup which we should take in any case (even by itself). - Patches 2-4 add the feature, basic support for it to the selftest, and docs. - Patches 5-6 make the selftest configurable, so you can test one or the other instead of always both. If we decide this is overcomplicated, we could just drop these two patches and take the rest of the series. Changelog: v2->v3: - Rebased onto linux-next/akpm-base, in order to be based on top of the run_vmtests.sh refactor which was merged previously. - Picked up some Reviewed-by's. - Fixed ioctl definition (_IO instead of _IOWR), and stopped using compat_ptr_ioctl since it is unneeded for ioctls which don't take a pointer. - Removed the "handle_kernel_faults" bool, simplifying the code. The result is logically equivalent, but simpler. - Fixed userfaultfd selftest so it returns KSFT_SKIP appropriately. - Reworded documentation per Shuah's feedback on v2. - Improved example usage for userfaultfd selftest. v1->v2: - Add documentation update. - Test *both* userfaultfd(2) and /dev/userfaultfd via the selftest.

THIS IS VERY CONFIDENTIAL

by Steve Dibenedetto

-- Hello, My name is Steve Dibenedetto.I apologize to have contacted you this way without a direct relationship. There is an opportunity to collaborate with me in the sourcing of some materials needed by our company for production of the different medicines we are researching. I'm aware that this might be totally outside your professional specialization, but it will be a great source for generating extra revenue. I discovered a manufacturer who can supply us at a lower rate than our company's previous purchases. I will give you more specific details when/if I receive feedback from you showing interest. Warm Regards Steve Dibenedetto Production & Control Manager, Green Field Laboratories Gothic House, Barker Gate, Nottingham, NG1 1JU, United Kingdom.
