Patch series "selftests, powerpc, x86: Memory Protection Keys", v19. Memory protection keys enables an application to protect its address space from inadvertent access by its own code. This feature is now enabled on powerpc and has been available since 4.16-rc1. The patches move the selftests to arch neutral directory and enhance their test coverage. Tested on powerpc64 and x86_64 (Skylake-SP). This patch (of 24): Move selftest files from tools/testing/selftests/x86/ to tools/testing/selftests/vm/. Signed-off-by:

When reading, read_pos should start with bytes_consumed, not file->f_pos. Because when there is more than one reader, the read_pos corresponding to file->f_pos may have been consumed, which will cause the data that has been consumed to be read and the bytes_consumed update error. Signed-off-by:

This code was using get_user_pages_fast(), in a "Case 2" scenario (DMA/RDMA), using the categorization from [1]. That means that it's time to convert the get_user_pages_fast() + put_page() calls to pin_user_pages_fast() + unpin_user_pages() calls. There is some helpful background in [2]: basically, this is a small part of fixing a long-standing disconnect between pinning pages, and file systems' use of those pages.

Fields of md(mport_dev) are set after cdev_device_add(). However, the file operation callbacks can be called after cdev_device_add() and therefore accesses to fields of md in the callbacks can race with the rest of the mport_cdev_add() function. One such example is INIT_LIST_HEAD(&md->portwrites) in mport_cdev_add(), the list is initialised after cdev_device_add(). This can race with list_add_tail(&pw_filter->md_node,&md->portwrites) in rio_mport_add_pw_filter() which is called by unlocked_ioctl. To avoid such data races use cdev_device_add() after initializing md. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

Currently copy_string_kernel is just a wrapper around copy_strings that simplifies the calling conventions and uses set_fs to allow passing a kernel pointer. But due to the fact the we only need to handle a single kernel argument pointer, the logic can be sigificantly simplified while getting rid of the set_fs. Signed-off-by:

Some init systems (eg. systemd) have init at their own paths, for example, /usr/lib/systemd/systemd. A compatibility symlink to one of the hardcoded init paths is provided by another package, usually named something like systemd-sysvcompat or similar. Currently distro maintainers who are hands-off on the bootloader are more or less required to include those compatibility links as part of their base distribution, because it's hard to migrate away from them since there's a risk some users will not get the message to set init= on the kernel command line appropriately. Moreover, for distributions where the init system is something the distribution itself is opinionated about (eg. Arch, which has systemd in the required `base` package), we could usually reasonably configure this ahead of time when building the distribution kernel. However, we currently simply don't have any way to configure the kernel to do this. Here's an example discussion where removing sysvcompat was discussed by distro maintainers[0]. This patch adds a new Kconfig tunable, CONFIG_DEFAULT_INIT, which if set is tried before the hardcoded fallback list. So the order of precedence is now thus: 1. init= on command line (on failure: panic) 2. CONFIG_DEFAULT_INIT (on failure: try #3) 3. Hardcoded fallback list (on failure: panic) This new config parameter will allow distribution maintainers to move away from these compatibility links safely, without having to worry that their users might not have the right init=. There are also two other benefits of this over having the distribution maintain a symlink: 1. One of the value propositions over simply having distributions maintain a /sbin/init symlink via a package is that it also frees distributions which have a preferred default, but not mandatory, init system from having their package manager fight with their users for control of /{s,}bin/init. Instead, the distribution simply makes their preference known in CONFIG_DEFAULT_INIT, and if the user installs another init system and uninstalls the default one they can still make use of /{s,}bin/init and friends for their own uses. This makes more cases Just Work(tm) without the user having to perform extra configuration via init=. 2. Since before this we don't know which path the distribution actually _intends_ to serve init from, we don't pr_err if it is simply missing, and usually will just silently put the user in a /bin/sh shell. Now that the distribution can make a declaration of intent, we can be more vocal when this init system fails to launch for any reason, even if it's simply because no file exists at that location, speeding up the palaver of init/mount dependency/etc debugging a bit.

ELFNOTE_START allows callers to specify flags for .pushsection assembler directives. All callsites but ELF_NOTE use "a" for SHF_ALLOC. For vdso's that explicitly use ELF_NOTE_START and BUILD_SALT, the same section is specified twice after preprocessing, once with "a" flag, once without. Example: .pushsection .note.Linux, "a", @note ; .pushsection .note.Linux, "", @note ; While GNU as allows this ordering, it warns for the opposite ordering, making these directives position dependent. We'd prefer not to precisely match this behavior in Clang's integrated assembler. Instead, the non __ASSEMBLY__ definition of ELF_NOTE uses __attribute__((section(".note.Linux"))) which is created with SHF_ALLOC, so let's make the __ASSEMBLY__ definition of ELF_NOTE consistent with C and just always use "a" flag. This allows Clang to assemble a working mainline (5.6) kernel via: $ make CC=clang AS=clang Signed-off-by:Nick Desaulniers <ndesaulniers@google.com> Signed-off-by:

While "git am" can apply an mbox file containing multiple patches (e.g. as created by b4[1], or a patch bundle downloaded from patchwork), checkpatch does not have proper support for that. When operating on an mbox, checkpatch will merge all detected tags, and complain falsely about duplicates: WARNING: Duplicate signature As modifying checkpatch to reset state in between each patch is a lot of work, a simple solution is splitting the mbox into individual patches, and invoking checkpatch for each of them. Fortunately checkpatch can read a patch from stdin, so the classic "formail" tool can be used to split the mbox, and pipe all individual patches to checkpatch: formail -s scripts/checkpatch.pl < my-mbox However, when reading a patch file from standard input, checkpatch calls it "Your patch", and reports its state as: Your patch has style problems, please review. or: Your patch has no obvious style problems and is ready for submission. Hence it can be difficult to identify which patches need to be reviewed and improved. Fix this by replacing "Your patch" by (the first line of) the email subject, if present. Note that "git mailsplit" can also be used to split an mbox, but it will create individual files for each patch, thus requiring cleanup afterwards. Formail does not have this disadvantage.

Test some bit clears/sets to make sure assembly doesn't change, and that the set_bit and clear_bit functions work and don't cause sparse warnings. Instruct Kbuild to build this file with extra warning level -Wextra, to catch new issues, and also doesn't hurt to build with C=1. This was used to test changes to arch/x86/include/asm/bitops.h. In particular, sparse (C=1) was very concerned when the last bit before a natural boundary, like 7, or 31, was being tested, as this causes sign extension (0xffffff7f) for instance when clearing bit 7. Recommended usage: make defconfig scripts/config -m CONFIG_TEST_BITOPS make modules_prepare make C=1 W=1 lib/test_bitops.ko objdump -S -d lib/test_bitops.ko insmod lib/test_bitops.ko rmmod lib/test_bitops.ko <check dmesg>, there should be no compiler/sparse warnings and no error messages in log.

The zlib inflate code has an old micro-optimization based on the assumption that for pre-increment memory accesses, the compiler will generate code that fits better into the processor's pipeline than what would be generated for post-increment memory accesses. This optimization was already removed in upstream zlib in 2016: https://github.com/madler/zlib/commit/9aaec95e8211 This optimization causes UB according to C99, which says in section 6.5.6 "Additive operators": "If both the pointer operand and the result point to elements of the same array object, or one past the last element of the array object, the evaluation shall not produce an overflow; otherwise, the behavior is undefined". This UB is not only a theoretical concern, but can also cause trouble for future work on compiler-based sanitizers. According to the zlib commit, this optimization also is not optimal anymore with modern compilers. Replace uses of OFF, PUP and UP_UNALIGNED with their definitions in the POSTINC case, and remove the macro definitions, just like in the upstream patch. Signed-off-by:

In order to be more consistent with other files, use a more standard convention and put these newlines back in the messages themselves and remove it from the pr_fmt macro.
