[PATCH v2] selftests/zram: avoid subshells and bc for ratio calculations

by David Disseldorp

Awk is already called for /sys/block/zram#/mm_stat parsing, so use it to also perform the floating point capacity vs consumption ratio calculations. The test output is unchanged. This allows bc to be dropped as a dependency for the zram selftests. The documented free dependency can also be removed following d18da7ec37195 ("selftests/zram01.sh: Fix compression ratio calculation") Signed-off-by: David Disseldorp <ddiss(a)suse.de> --- tools/testing/selftests/zram/README | 2 -- tools/testing/selftests/zram/zram01.sh | 18 ++++++++---------- 2 files changed, 8 insertions(+), 12 deletions(-) v2: drop unused dependencies from selftests/zram/README diff --git a/tools/testing/selftests/zram/README b/tools/testing/selftests/zram/README index 110b34834a6fa..510ca5a1087f5 100644 --- a/tools/testing/selftests/zram/README +++ b/tools/testing/selftests/zram/README @@ -27,9 +27,7 @@ zram01.sh: creates general purpose ram disks with ext4 filesystems zram02.sh: creates block device for swap Commands required for testing: - - bc - dd - - free - awk - mkswap - swapon diff --git a/tools/testing/selftests/zram/zram01.sh b/tools/testing/selftests/zram/zram01.sh index 8f4affe34f3e4..df1b1d4158989 100755 --- a/tools/testing/selftests/zram/zram01.sh +++ b/tools/testing/selftests/zram/zram01.sh @@ -33,7 +33,7 @@ zram_algs="lzo" zram_fill_fs() { - for i in $(seq $dev_start $dev_end); do + for ((i = $dev_start; i <= $dev_end && !ERR_CODE; i++)); do echo "fill zram$i..." local b=0 while [ true ]; do @@ -44,15 +44,13 @@ zram_fill_fs() done echo "zram$i can be filled with '$b' KB" - local mem_used_total=`awk '{print $3}' "/sys/block/zram$i/mm_stat"` - local v=$((100 * 1024 * $b / $mem_used_total)) - if [ "$v" -lt 100 ]; then - echo "FAIL compression ratio: 0.$v:1" - ERR_CODE=-1 - return - fi - - echo "zram compression ratio: $(echo "scale=2; $v / 100 " | bc):1: OK" + awk -v b="$b" '{ v = (100 * 1024 * b / $3) } END { + if (v < 100) { + printf "FAIL compression ratio: 0.%u:1\n", v + exit 1 + } + printf "zram compression ratio: %.2f:1: OK\n", v / 100 + }' "/sys/block/zram$i/mm_stat" || ERR_CODE=-1 done } -- 2.35.3

The GetWriteWatch{} retrieves the addresses of the pages that are written to in a region of virtual memory. This syscall is used in Windows applications and games etc. This syscall is being emulated in pretty slow manner in userspace. Our purpose is to enhance the kernel such that we translate it efficiently in a better way. Currently some out of tree hack patches are being used to efficiently emulate it in some kernels. We intend to replace those with these patches. So the whole gaming on Linux can effectively get benefit from this. It means there would be tons of users of this code. CRIU use case [2] was mentioned by Andrei and Danylo: > Use cases for migrating sparse VMAs are binaries sanitized with ASAN, > MSAN or TSAN [3]. All of these sanitizers produce sparse mappings of > shadow memory [4]. Being able to migrate such binaries allows to highly > reduce the amount of work needed to identify and fix post-migration > crashes, which happen constantly. Andrei's defines the following uses of this code: * it is more granular and allows us to track changed pages more effectively. The current interface can clear dirty bits for the entire process only. In addition, reading info about pages is a separate operation. It means we must freeze the process to read information about all its pages, reset dirty bits, only then we can start dumping pages. The information about pages becomes more and more outdated, while we are processing pages. The new interface solves both these downsides. First, it allows us to read pte bits and clear the soft-dirty bit atomically. It means that CRIU will not need to freeze processes to pre-dump their memory. Second, it clears soft-dirty bits for a specified region of memory. It means CRIU will have actual info about pages to the moment of dumping them. * The new interface has to be much faster because basic page filtering is happening in the kernel. With the old interface, we have to read pagemap for each page. *Implementation Evolution (Short Summary)* From the definition of GetWriteWatch(), we feel like kernel's soft-dirty feature can be used under the hood with some additions like: * reset soft-dirty flag for only a specific region of memory instead of clearing the flag for the entire process * get and clear soft-dirty flag for a specific region atomically So we decided to use ioctl on pagemap file to read or/and reset soft-dirty flag. But using soft-dirty flag, sometimes we get extra pages which weren't even written. They had become soft-dirty because of VMA merging and VM_SOFTDIRTY flag. This breaks the definition of GetWriteWatch(). We were able to by-pass this short coming by ignoring VM_SOFTDIRTY until David reported that mprotect etc messes up the soft-dirty flag while ignoring VM_SOFTDIRTY [5]. This wasn't happening until [6] got introduced. We discussed if we can revert these patches. But we could not reach to any conclusion. So at this point, I made couple of tries to solve this whole VM_SOFTDIRTY issue by correcting the soft-dirty implementation: * [7] Correct the bug fixed wrongly back in 2014. It had potential to cause regression. We left it behind. * [8] Keep a list of soft-dirty part of a VMA across splits and merges. I got the reply don't increase the size of the VMA by 8 bytes. At this point, we left soft-dirty considering it is too much delicate and userfaultfd [9] seemed like the only way forward. From there onward, we have been basing soft-dirty emulation on userfaultfd wp feature where kernel resolves the faults itself when WP_ASYNC feature is used. It was straight forward to add WP_ASYNC feature in userfautlfd. Now we get only those pages dirty or written-to which are really written in reality. (PS There is another WP_UNPOPULATED userfautfd feature is required which is needed to avoid pre-faulting memory before write-protecting [9].) All the different masks were added on the request of CRIU devs to create interface more generic and better.

As kernel already has soft-dirty feature inside which we have given up to use, we are using written-to terminology while using UFFD async WP under the hood. This IOCTL, PAGEMAP_SCAN on pagemap file can be used to get and/or clear the info about page table entries. The following operations are supported in this ioctl: - Get the information if the pages have been written-to (PAGE_IS_WRITTEN), file mapped (PAGE_IS_FILE), present (PAGE_IS_PRESENT) or swapped (PAGE_IS_SWAPPED). - Write-protect the pages (PAGEMAP_WP_ENGAGE) to start finding which pages have been written-to. - Find pages which have been written-to and write protect the pages (atomic PAGE_IS_WRITTEN + PAGEMAP_WP_ENGAGE) It is possible to find and clear soft-dirty pages entirely in userspace. But it isn't efficient: - The mprotect and SIGSEGV handler for bookkeeping - The userfaultfd wp (synchronous) with the handler for bookkeeping Some benchmarks can be seen here[1]. This series adds features that weren't present earlier: - There is no atomic get soft-dirty/Written-to status and clear present in the kernel. - The pages which have been written-to can not be found in accurate way. (Kernel's soft-dirty PTE bit + sof_dirty VMA bit shows more soft-dirty pages than there actually are.) Historically, soft-dirty PTE bit tracking has been used in the CRIU project. The procfs interface is enough for finding the soft-dirty bit status and clearing the soft-dirty bit of all the pages of a process. We have the use case where we need to track the soft-dirty PTE bit for only specific pages on-demand. We need this tracking and clear mechanism of a region of memory while the process is running to emulate the getWriteWatch() syscall of Windows. *(Moved to using UFFD instead of soft-dirtyi feature to find pages which have been written-to from v7 patch series)*: Stop using the soft-dirty flags for finding which pages have been written to. It is too delicate and wrong as it shows more soft-dirty pages than the actual soft-dirty pages. There is no interest in correcting it [2][3] as this is how the feature was written years ago. It shouldn't be updated to changed behaviour. Peter Xu has suggested using the async version of the UFFD WP [4] as it is based inherently on the PTEs. So in this patch series, I've added a new mode to the UFFD which is asynchronous version of the write protect. When this variant of the UFFD WP is used, the page faults are resolved automatically by the kernel. The pages which have been written-to can be found by reading pagemap file (!PM_UFFD_WP). This feature can be used successfully to find which pages have been written to from the time the pages were write protected. This works just like the soft-dirty flag without showing any extra pages which aren't soft-dirty in reality. The information related to pages if the page is file mapped, present and swapped is required for the CRIU project [5][6]. The addition of the required mask, any mask, excluded mask and return masks are also required for the CRIU project [5]. The IOCTL returns the addresses of the pages which match the specific masks. The page addresses are returned in struct page_region in a compact form. The max_pages is needed to support a use case where user only wants to get a specific number of pages. So there is no need to find all the pages of interest in the range when max_pages is specified. The IOCTL returns when the maximum number of the pages are found. The max_pages is optional. If max_pages is specified, it must be equal or greater than the vec_size. This restriction is needed to handle worse case when one page_region only contains info of one page and it cannot be compacted. This is needed to emulate the Windows getWriteWatch() syscall. The patch series include the detailed selftest which can be used as an example for the uffd async wp test and PAGEMAP_IOCTL. It shows the interface usages as well.

[PATCH v2 00/12] tools/nolibc: shrink arch support

by Zhangjin Wu

Hi, Willy This is v2 of the "tools/nolibc: shrink arch support" [1]. This v2 has no core code logic change, but applies some suggestions from Willy and Thomas, one is using post-whitespaces instead of post-tab, another is restructuring the arch support directory and files [2]. Like musl, this v2 creates <ARCH> directory for every arch and splits the old arch-<ARCH>.h to <ARCH>/{crt.h, sys.h} and at the same time, splits the old arch.h to crt_arch.h and sys_arch.h. at last, only need to include crt_arch.h in crt.h and sys_arch.h in sys.h respectively, and no longer need to include arch.h in the other common headers: crt.h <-- crt_arch.h <-- <ARCH>/crt.h sys.h <-- sys_arch.h <-- <ARCH>/sys.h It is based on the 20230705-nolibc-series2 branch of nolibc repo [3]. It should be applied after the v6 __sysret helper series [4] and the v4 min config support series [5]. Here is the test report for all of the supported architectures: arch/board | result ------------|------------ arm/vexpress-a9 | 142 test(s) passed, 1 skipped, 0 failed. arm/virt | 142 test(s) passed, 1 skipped, 0 failed. aarch64/virt | 142 test(s) passed, 1 skipped, 0 failed. ppc/g3beige | not supported ppc/ppce500 | not supported i386/pc | 142 test(s) passed, 1 skipped, 0 failed. x86_64/pc | 142 test(s) passed, 1 skipped, 0 failed. mipsel/malta | 142 test(s) passed, 1 skipped, 0 failed. loongarch64/virt | 142 test(s) passed, 1 skipped, 0 failed. riscv64/virt | 142 test(s) passed, 1 skipped, 0 failed. riscv32/virt | 0 test(s) passed, 0 skipped, 0 failed. s390x/s390-ccw-virtio | 142 test(s) passed, 1 skipped, 0 failed. Changes from v1 --> v2: * tools/nolibc: rename arch-<ARCH>.h to <ARCH>/arch.h tools/nolibc: split arch.h to crt.h and sys.h Restruct the arch support directory and files. Fix up the errors reported by scripts/checkpatch.pl. * tools/nolibc: sys.h: remove the old sys_stat support Rebase on the new arch support directory and files. * tools/nolibc: crt.h: add _start_c Move #include "compiler.h" in the common crt.h too. * tools/nolibc: arm/crt.h: shrink _start with _start_c tools/nolibc: aarch64/crt.h: shrink _start with _start_c tools/nolibc: i386/crt.h: shrink _start with _start_c tools/nolibc: x86_64/crt.h: shrink _start with _start_c tools/nolibc: mips/crt.h: shrink _start with _start_c tools/nolibc: loongarch/crt.h: shrink _start with _start_c tools/nolibc: riscv/crt.h: shrink _start with _start_c tools/nolibc: s390/crt.h: shrink _start with _start_c Rebase on the new arch support directory and files.

[PATCH bpf-next v5 0/7] Add SO_REUSEPORT support for TC bpf_sk_assign

by Lorenz Bauer

We want to replace iptables TPROXY with a BPF program at TC ingress. To make this work in all cases we need to assign a SO_REUSEPORT socket to an skb, which is currently prohibited. This series adds support for such sockets to bpf_sk_assing. I did some refactoring to cut down on the amount of duplicate code. The key to this is to use INDIRECT_CALL in the reuseport helpers. To show that this approach is not just beneficial to TC sk_assign I removed duplicate code for bpf_sk_lookup as well. Joint work with Daniel Borkmann.

[PATCH] selftests/arm64: fix build failure during the "emit_tests" step

by John Hubbard

The build failure reported in [1] occurred because commit 9fc96c7c19df ("selftests: error out if kernel header files are not yet built") added a new "kernel_header_files" dependency to "all", and that triggered another, pre-existing problem. Specifically, the arm64 selftests override the emit_tests target, and that override improperly declares itself to depend upon the "all" target. This is a problem because the "emit_tests" target in lib.mk was not intended to be overridden. emit_tests is a very simple, sequential build target that was originally invoked from the "install" target, which in turn, depends upon "all". That approach worked for years. But with 9fc96c7c19df in place, emit_tests failed, because it does not set up all of the elaborate things that "install" does. And that caused the new "kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being correct) to fail. Some detail: The "all" target is .PHONY. Therefore, each target that depends on "all" will cause it to be invoked again, and because dependencies are managed quite loosely in the selftests Makefiles, many things will run, even "all" is invoked several times in immediate succession. So this is not a "real" failure, as far as build steps go: everything gets built, but "all" reports a problem when invoked a second time from a bad environment. To fix this, simply remove the unnecessary "all" dependency from the overridden emit_tests target. The dependency is still effectively honored, because again, invocation is via "install", which also depends upon "all". An alternative approach would be to harden the emit_tests target so that it can depend upon "all", but that's a lot more complicated and hard to get right, and doesn't seem worth it, especially given that emit_tests should probably not be overridden at all.
