[RFC v1 0/6] kunit: Add test attributes API

by Rae Moar

Hello everyone, This is an RFC patch series to propose the addition of a test attributes framework to KUnit. There has been interest in filtering out "slow" KUnit tests. Most notably, a new config, CONFIG_MEMCPY_SLOW_KUNIT_TEST, has been added to exclude particularly slow memcpy tests (https://lore.kernel.org/all/20230118200653.give.574-kees@kernel.org/). This proposed attributes framework would be used to save and access test associated data, including whether a test is slow. These attributes would be reportable (via KTAP and command line output) and some will be filterable. This framework is designed to allow for the addition of other attributes in the future. These attributes could include whether the test is flaky, associated test files, etc. Note that this could intersect with the discussions on how to format test-associated data in KTAP v2 that I am also involved in (https://lore.kernel.org/all/20230420205734.1288498-1-rmoar@google.com/). If the overall idea seems good, I'll make sure to add tests/documentation, and more patches marking existing tests as slow to the patch series. Thanks!

[PATCH v12 0/5] Implement IOCTL to get and optionally clear info about PTEs

by Muhammad Usama Anjum

*Changes in v12* - Update and other memory types to UFFD_FEATURE_WP_ASYNC - Rebaase on top of next-20230406 - Review updates *Changes in v11* - Rebase on top of next-20230307 - Base patches on UFFD_FEATURE_WP_UNPOPULATED - Do a lot of cosmetic changes and review updates - Remove ENGAGE_WP + !GET operation as it can be performed with UFFDIO_WRITEPROTECT *Changes in v10* - Add specific condition to return error if hugetlb is used with wp async - Move changes in tools/include/uapi/linux/fs.h to separate patch - Add documentation *Changes in v9:* - Correct fault resolution for userfaultfd wp async - Fix build warnings and errors which were happening on some configs - Simplify pagemap ioctl's code *Changes in v8:* - Update uffd async wp implementation - Improve PAGEMAP_IOCTL implementation *Changes in v7:* - Add uffd wp async - Update the IOCTL to use uffd under the hood instead of soft-dirty flags *Motivation* The real motivation for adding PAGEMAP_SCAN IOCTL is to emulate Windows GetWriteWatch() syscall [1]. 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 v3 0/4] Check if FIPS mode is enabled when running selftests

by Magali Lemes

Some test cases from net/tls, net/fcnal-test and net/vrf-xfrm-tests that rely on cryptographic functions to work and use non-compliant FIPS algorithms fail in FIPS mode. In order to allow these tests to pass in a wider set of kernels, - for net/tls, skip the test variants that use the ChaCha20-Poly1305 and SM4 algorithms, when FIPS mode is enabled; - for net/fcnal-test, skip the MD5 tests, when FIPS mode is enabled; - for net/vrf-xfrm-tests, replace the algorithms that are not FIPS-compliant with compliant ones. Changes in v3: - Add new commit to allow skipping test directly from test setup. - No need to initialize static variable to zero. - Skip tests during test setup only. - Use the constructor attribute to set fips_enabled before entering main(). Changes in v2: - Add R-b tags. - Put fips_non_compliant into the variants. - Turn fips_enabled into a static global variable. - Read /proc/sys/crypto/fips_enabled only once at main(). v1: https://lore.kernel.org/netdev/20230607174302.19542-1-magali.lemes@canonica… v2: https://lore.kernel.org/netdev/20230609164324.497813-1-magali.lemes@canonic… Magali Lemes (4): selftests/harness: allow tests to be skipped during setup selftests: net: tls: check if FIPS mode is enabled selftests: net: vrf-xfrm-tests: change authentication and encryption algos selftests: net: fcnal-test: check if FIPS mode is enabled tools/testing/selftests/kselftest_harness.h | 6 ++-- tools/testing/selftests/net/fcnal-test.sh | 27 +++++++++++----- tools/testing/selftests/net/tls.c | 25 ++++++++++++++- tools/testing/selftests/net/vrf-xfrm-tests.sh | 32 +++++++++---------- 4 files changed, 62 insertions(+), 28 deletions(-) -- 2.34.1

[PATCH net 00/17] selftests: mptcp: skip tests not supported by old kernels (part 3)

by Matthieu Baerts

After a few years of increasing test coverage in the MPTCP selftests, we realised [1] the last version of the selftests is supposed to run on old kernels without issues. Supporting older versions is not that easy for this MPTCP case: these selftests are often validating the internals by checking packets that are exchanged, when some MIB counters are incremented after some actions, how connections are getting opened and closed in some cases, etc. In other words, it is not limited to the socket interface between the userspace and the kernelspace. In addition to that, the current MPTCP selftests run a lot of different sub-tests but the TAP13 protocol used in the selftests don't support sub-tests: one failure in sub-tests implies that the whole selftest is seen as failed at the end because sub-tests are not tracked. It is then important to skip sub-tests not supported by old kernels. To minimise the modifications and reduce the complexity to support old versions, the idea is to look at external signs and skip the whole selftest or just some sub-tests before starting them. This cannot be applied in all cases. Similar to the second part, this third one focuses on marking different sub-tests as skipped if some MPTCP features are not supported. This time, only in "mptcp_join.sh" selftest, the remaining one, is modified. Several techniques are used here to achieve this task: - Before starting some tests: - Check if a file (sysctl knob) is present: that's what patch 12/17 is doing for the userspace PM feature. - Check if a required kernel symbol is present in /proc/kallsyms: patches 9, 10, 14 and 15/17 are using this technique. - Check if it is possible to setup a particular network environment requiring Netfilter or TC: if the preparation step fail, the linked sub-test is marked as skipped. Patch 5/17 is doing that. - Check if a MIB counter is available: patches 7 and 13/17 do that. - Check if the kernel version is newer than a specific one: patch 1/17 adds some helpers in mptcp_lib.sh to ease its use. That's not ideal and it is only used as last resort but as mentioned above, it is important to skip tests if they are not supported not to have the whole selftest always being marked as failed on old kernels. Patches 11 and 17/17 are checking the kernel version. An alternative would be to ignore the results for some sub-tests but that's not ideal too. Note that SELFTESTS_MPTCP_LIB_NO_KVERSION_CHECK env var can be set to 1 not to skip these tests if the running kernel doesn't have a supported version. - After having launched the tests: - Adapt the expectations depending on the presence of a kernel symbol (patch 6/17) or a kernel version (patch 8/17). - Check is a MIB counter is available and skip the verification if not. Patch 4/17 is using this technique. Before skipping tests, SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var value is checked: if it is set to 1, the test is marked as "failed" instead of "skipped". MPTCP public CI expects to have all features supported and it sets this env var to 1 to catch regressions in these new checks. Patch 2/17 uses 'iptables-legacy' if available because it might be needed when using an older kernel not supporting iptables-nft. Patch 3/17 adds some helpers used in the other patches mentioned to easily mark sub-tests as skipped. Patch 16/17 uniforms MPTCP Join "listener" tests: it was imported code from userspace_pm.sh but without using the "code style" and ways of using tools and printing messages from MPTCP Join selftest.

Also, this will conflict with commit 0639fa230a21 ("selftests: mptcp: add explicit check for new mibs") that is currently in net-next but not in -net. Here is the resolution. It is a bit long but you will see, it is simple: take the version from -net with get_counter() and for the last one, move the new call to chk_rm_tx_nr() inside the 'if' statement: ------------------- 8< ------------------- diff --cc tools/testing/selftests/net/mptcp/mptcp_join.sh index 0ae8cafde439,85474e029784..bd47cdc2bd15 --- a/tools/testing/selftests/net/mptcp/mptcp_join.sh +++ b/tools/testing/selftests/net/mptcp/mptcp_join.sh @@@ -1360,27 -1265,23 +1355,25 @@@ chk_fclose_nr( fi printf "%-${nr_blank}s %s" " " "ctx" - count=$(ip netns exec $ns_tx nstat -as | grep MPTcpExtMPFastcloseTx | awk '{print $2}') - [ -z "$count" ] && count=0 - [ "$count" != "$fclose_tx" ] && extra_msg="$extra_msg,tx=$count" - if [ "$count" != "$fclose_tx" ];

[PATCH bpf v3 0/2] bpf: fix NULL dereference during extable search

by Krister Johansen

Hi, Enclosed are a pair of patches for an oops that can occur if an exception is generated while a bpf subprogram is running. One of the bpf_prog_aux entries for the subprograms are missing an extable. This can lead to an exception that would otherwise be handled turning into a NULL pointer bug. When run out of the selftest, the oops looks like this: BUG: kernel NULL pointer dereference, address: 000000000000000c #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 1132 Comm: test_progs Tainted: G OE 6.4.0-rc3+ #2 RIP: 0010:cmp_ex_search+0xb/0x30 Code: cc cc cc cc e8 36 cb 03 00 66 0f 1f 44 00 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 f3 0f 1e fa 55 48 89 e5 48 8b 07 <48> 63 0e 48 01 f1 31 d2 48 39 c8 19 d2 48 39 c8 b8 01 00 00 00 0f RSP: 0018:ffffb30c4291f998 EFLAGS: 00010006 RAX: ffffffffc00b49da RBX: 0000000000000002 RCX: 000000000000000c RDX: 0000000000000002 RSI: 000000000000000c RDI: ffffb30c4291f9e8 RBP: ffffb30c4291f998 R08: ffffffffab1a42d0 R09: 0000000000000001 R10: 0000000000000000 R11: ffffffffab1a42d0 R12: ffffb30c4291f9e8 R13: 000000000000000c R14: 000000000000000c R15: 0000000000000000 FS: 00007fb5d9e044c0(0000) GS:ffff92e95ee00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000000000000c CR3: 000000010c3a2005 CR4: 00000000007706f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 PKRU: 55555554 Call Trace: <TASK> bsearch+0x41/0x90 ? __pfx_cmp_ex_search+0x10/0x10 ? bpf_prog_45a7907e7114d0ff_handle_fexit_ret_subprogs3+0x2a/0x6c search_extable+0x3b/0x60 ? bpf_prog_45a7907e7114d0ff_handle_fexit_ret_subprogs3+0x2a/0x6c search_bpf_extables+0x10d/0x190 ? bpf_prog_45a7907e7114d0ff_handle_fexit_ret_subprogs3+0x2a/0x6c search_exception_tables+0x5d/0x70 fixup_exception+0x3f/0x5b0 ? look_up_lock_class+0x61/0x110 ? __lock_acquire+0x6b8/0x3560 ? __lock_acquire+0x6b8/0x3560 ? __lock_acquire+0x6b8/0x3560 kernelmode_fixup_or_oops+0x46/0x110 __bad_area_nosemaphore+0x68/0x2b0 ? __lock_acquire+0x6b8/0x3560 bad_area_nosemaphore+0x16/0x20 do_kern_addr_fault+0x81/0xa0 exc_page_fault+0xd6/0x210 asm_exc_page_fault+0x2b/0x30 RIP: 0010:bpf_prog_45a7907e7114d0ff_handle_fexit_ret_subprogs3+0x2a/0x6c Code: f3 0f 1e fa 0f 1f 44 00 00 66 90 55 48 89 e5 f3 0f 1e fa 48 8b 7f 08 49 bb 00 00 00 00 00 80 00 00 4c 39 df 73 04 31 f6 eb 04 <48> 8b 77 00 49 bb 00 00 00 00 00 80 00 00 48 81 c7 7c 00 00 00 4c RSP: 0018:ffffb30c4291fcb8 EFLAGS: 00010282 RAX: 0000000000000001 RBX: 0000000000000001 RCX: 0000000000000000 RDX: 00000000cddf1af1 RSI: 000000005315a00d RDI: ffffffffffffffea RBP: ffffb30c4291fcb8 R08: ffff92e644bf38a8 R09: 0000000000000000 R10: 0000000000000000 R11: 0000800000000000 R12: ffff92e663652690 R13: 00000000000001c8 R14: 00000000000001c8 R15: 0000000000000003 bpf_trampoline_251255721842_2+0x63/0x1000 bpf_testmod_return_ptr+0x9/0xb0 [bpf_testmod] ? bpf_testmod_test_read+0x43/0x2d0 [bpf_testmod] sysfs_kf_bin_read+0x60/0x90 kernfs_fop_read_iter+0x143/0x250 vfs_read+0x240/0x2a0 ksys_read+0x70/0xe0 __x64_sys_read+0x1f/0x30 do_syscall_64+0x68/0xa0 ? syscall_exit_to_user_mode+0x77/0x1f0 ? do_syscall_64+0x77/0xa0 ? irqentry_exit+0x35/0xa0 ? sysvec_apic_timer_interrupt+0x4d/0x90 entry_SYSCALL_64_after_hwframe+0x72/0xdc RIP: 0033:0x7fb5da00a392 Code: ac 00 00 f7 d8 64 89 02 48 c7 c0 ff ff ff ff eb be 0f 1f 80 00 00 00 00 f3 0f 1e fa 64 8b 04 25 18 00 00 00 85 c0 75 10 0f 05 <48> 3d 00 f0 ff ff 77 56 c3 0f 1f 44 00 00 48 83 ec 28 48 89 54 24 RSP: 002b:00007ffc5b3cab68 EFLAGS: 00000246 ORIG_RAX: 0000000000000000 RAX: ffffffffffffffda RBX: 000055bee7b8b100 RCX: 00007fb5da00a392 RDX: 00000000000001c8 RSI: 0000000000000000 RDI: 0000000000000009 RBP: 00007ffc5b3caba0 R08: 0000000000000000 R09: 0000000000000037 R10: 000055bee7b8c2a7 R11: 0000000000000246 R12: 000055bee78f1f60 R13: 00007ffc5b3cae90 R14: 0000000000000000 R15: 0000000000000000 </TASK> Modules linked in: bpf_testmod(OE) nls_iso8859_1 dm_multipath scsi_dh_rdac scsi_dh_emc scsi_dh_alua intel_rapl_msr intel_rapl_common intel_uncore_frequency_common ppdev nfit crct10dif_pclmul crc32_pclmul psmouse ghash_clmulni_intel sha512_ssse3 aesni_intel parport_pc crypto_simd cryptd input_leds parport rapl ena i2c_piix4 mac_hid serio_raw ramoops reed_solomon pstore_blk drm pstore_zone efi_pstore autofs4 [last unloaded: bpf_testmod(OE)] CR2: 000000000000000c These changes were tested via the verifier and progs selftests and no regressions were observed.

[PATCH v2 0/6] Landlock support for UML

by Mickaël Salaün

Hi, Commit cb2c7d1a1776 ("landlock: Support filesystem access-control") introduced a new ARCH_EPHEMERAL_INODES configuration, only enabled for User-Mode Linux. The reason was that UML's hostfs managed inodes in an ephemeral way: from the kernel point of view, the same inode struct could be created several times while being used by user space because the kernel didn't hold references to inodes. Because Landlock (and probably other subsystems) ties properties (i.e. access rights) to inode objects, it wasn't possible to create rules that match inodes and then allow specific accesses. This patch series fixes the way UML manages inodes according to the underlying filesystem. They are now properly handles as for other filesystems, which enables to support Landlock (and probably other features). Changes since v1: https://lore.kernel.org/r/20230309165455.175131-1-mic@digikod.net - Remove Cc stable@ (suggested by Richard). - Add Acked-by: Richard Weinberger to the first patch. - Split the test patch into two patches: one for the common pseudo-filesystems, and another patch dedicated to hostfs. - Remove CONFIG_SECURITY_PATH because it is useless for merge_config.sh - Move CONFIG_HOSTFS to a new config.um file. - Fix commit message spelling and test warnings. - Improve prepare_layout_opt() with remove_path() call to avoid cascading errors when some tested filesystems are not supported. - Remove cgroup-v1 tests because this filesystem cannot really be mounted several times. - Add test coverage with and without kernel debug code, according to GCC 12 and GCC 13.

[PATCH 1/2] selftests: mm: remove wrong kernel header inclusion

by Muhammad Usama Anjum

It is wrong to include unprocessed user header files directly. They are processed to "<source_tree>/usr/include" by running "make headers" and they are included in selftests by kselftest makefiles automatically with help of KHDR_INCLUDES variable. These headers should always bulilt first before building kselftests.

Here is a series with some fixes and cleanups to resctrl selftests. In v3, the rewritten CAT test is not included as an issue was discovered in one of its components requiring further work before it can be included to mainline. v3: - Don't include rewritten CAT test into this series! - Tweak wildcard style in Makefile - Fix many changelog typos, remove some wrong claims, and generally improve them. - Add fix to PARENT_EXIT() to unmount resctrl FS - Add unmounting resctrl FS before starting any tests - Add fix for buf leak - Add fix for perf fd closing - Split mount/remount/umount patches differently - Use size_t and %zu for span - Keep MBM print as MB, only internally use span in bytes - Drop start_buf global from fill_buf v2 (was sent with CAT test rewrite which is no longer included in v3): - Rebased on top of next to solve the conflicts - Added 2 patches related to resctrl FS mount/umount (fix + cleanup) - Consistently use "alloc" in cache_alloc_size() - CAT test error handling tweaked - Remove a spurious newline change from the CAT patch - Small improvements to changelogs Ilpo Järvinen (19): selftests/resctrl: Add resctrl.h into build deps selftests/resctrl: Don't leak buffer in fill_cache() selftests/resctrl: Unmount resctrl FS if child fails to run benchmark selftests/resctrl: Close perf value read fd on errors selftests/resctrl: Unmount resctrl FS before starting the first test selftests/resctrl: Move resctrl FS mount/umount to higher level selftests/resctrl: Refactor remount_resctrl(bool mum_resctrlfs) to mount_resctrl() selftests/resctrl: Remove mum_resctrlfs from struct resctrl_val_param selftests/resctrl: Convert span to size_t selftests/resctrl: Express span internally in bytes selftests/resctrl: Remove duplicated preparation for span arg selftests/resctrl: Remove "malloc_and_init_memory" param from run_fill_buf() selftests/resctrl: Remove unnecessary startptr global from fill_buf selftests/resctrl: Improve parameter consistency in fill_buf selftests/resctrl: Don't pass test name to fill_buf selftests/resctrl: Don't use variable argument list for ->setup() selftests/resctrl: Move CAT/CMT test global vars to function they are used in selftests/resctrl: Pass the real number of tests to show_cache_info() selftests/resctrl: Remove test type checks from cat_val() tools/testing/selftests/resctrl/Makefile | 2 +- tools/testing/selftests/resctrl/cache.c | 64 +++++++------- tools/testing/selftests/resctrl/cat_test.c | 28 ++---- tools/testing/selftests/resctrl/cmt_test.c | 29 ++----- tools/testing/selftests/resctrl/fill_buf.c | 87 +++++++------------ tools/testing/selftests/resctrl/mba_test.c | 9 +- tools/testing/selftests/resctrl/mbm_test.c | 17 ++-- tools/testing/selftests/resctrl/resctrl.h | 17 ++-- .../testing/selftests/resctrl/resctrl_tests.c | 82 +++++++++++------ tools/testing/selftests/resctrl/resctrl_val.c | 7 +- tools/testing/selftests/resctrl/resctrlfs.c | 57 ++++++------ 11 files changed, 169 insertions(+), 230 deletions(-) -- 2.30.2

[PATCH net-next v2] selftests: net: vxlan: Fix selftest regression after changes in iproute2.

by Vladimir Nikishkin

The iproute2 output that eventually landed upstream is different than the one used in this test, resulting in failures. Fix by adjusting the test to use iproute2's JSON output, which is more stable than regular output. Fixes: 305c04189997 ("selftests: net: vxlan: Add tests for vxlan nolocalbypass option.")

[BUG] selftests: drivers/net/bonding: bond-arp-interval-causes-panic.sh: Cannot find device "link1_1"

[BUG] selftests: alsa: pcm-test: premature timeout severs the test

by Mirsad Goran Todorovac

Hi, On several platforms, and for some time, I've noticed alsa: pcm-test TIMEOUT. I have tried to increase the timeout in selftests/alsa/settings: timeout=300, so I think there is no more purpose to further increase it, so something appears generally stuck. The test runs up to "default.time4.1.8 section where it hangs for more than 200 seconds, possibly indefinitely. The output of the selftest is: # # default.time3.1.8.0.PLAYBACK - 44.1kHz stereo large periods # # default.time3.1.8.0.PLAYBACK hw_params.RW_INTERLEAVED.S16_LE.44100.2.22496.202464 sw_params.202464 # ok 61 default.time3.0.3.0.PLAYBACK # # default.time4.0.3.0.PLAYBACK - 48kHz stereo small periods # # default.time4.0.3.0.PLAYBACK hw_params.RW_INTERLEAVED.S16_LE.48000.2.512.4096 sw_params.4096 # ok 62 default.time4.0.3.0.PLAYBACK # # default.time5.0.3.0.PLAYBACK - 48kHz stereo large periods # # default.time5.0.3.0.PLAYBACK hw_params.RW_INTERLEAVED.S16_LE.48000.2.24000.192000 sw_params.192000 # ok 63 default.time5.0.3.0.PLAYBACK # # default.time6.0.3.0.PLAYBACK - 48kHz 6 channel large periods # # default.time6.0.3.0.PLAYBACK hw_params.RW_INTERLEAVED.S16_LE.48000.2.48000.576000 sw_params.576000 # ok 64 default.time6.0.3.0.PLAYBACK # # default.time7.0.3.0.PLAYBACK - 96kHz stereo large periods # # default.time7.0.3.0.PLAYBACK hw_params.RW_INTERLEAVED.S16_LE.96000.2.48000.192000 sw_params.192000 # not ok 65 default.time3.1.8.0.PLAYBACK # # time mismatch: expected 4000ms got 17005 # # default.time4.1.8.# not ok 2 selftests: alsa: pcm-test # TIMEOUT 300 seconds The platform is AMD Ryzen 9 assembled box with AsRock mainboard. Config and Lshw attached. CONTINUED: Just to test further, I have increased timeout even further, to 400 seconds. Only then the test passed, but with numerous errors, and this is Ryzen 9, so I guess it can only be worse on hardware like i3 or i5. But many subtests failed, so I am submitting the entire test log (due to mailing list constraints to 100K size of attachments, it is compressed).

[PATCH v2 0/4] tools/nolibc: add two new syscall helpers

by Zhangjin Wu

Willy, Thomas This is the revision of the v1 syscall helpers [1], just rebased it on 20230606-nolibc-rv32+stkp7a of [2]. It doesn't conflict with the -ENOSYS patchset [3], so, it is ok to simply merge both of them. This revision mainly applied your suggestions of v1, both of the syscall return and call helpers are simplified or cleaned up. Changes from v1 -> v2: * tools/nolibc: sys.h: add __syscall() and __sysret() helpers * Use inline function instead of macro for the syscall return helper (Suggestion from Thomas) * Rename syscall return helper from __syscall_ret to __sysret (align with __syscall and it is not that long now) * Make __sysret() be always inline (Suggestion from Willy) * Simplify the whole __syscall() macro to oneline code (Benefit from the fixed 'long' return type of syscalls) * tools/nolibc: unistd.h: apply __sysret() helper * Convert the whole _syscall() macro to oneline code * tools/nolibc: sys.h: apply __sysret() helper * Futher convert both brk() and getpagesize() to oneline code * tools/nolibc: sys.h: apply __syscall() helper * Keep the same as v1, because the __syscall() usage not changed Best regards, Zhangjin --- [1]: https://lore.kernel.org/linux-riscv/cover.1685856497.git.falcon@tinylab.org/ [2]: https://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/nolibc.git [3]: https://lore.kernel.org/linux-riscv/cover.1685780412.git.falcon@tinylab.org/ Zhangjin Wu (4): tools/nolibc: sys.h: add __syscall() and __sysret() helpers tools/nolibc: unistd.h: apply __sysret() helper tools/nolibc: sys.h: apply __sysret() helper tools/nolibc: sys.h: apply __syscall() helper tools/include/nolibc/sys.h | 366 ++++++---------------------------- tools/include/nolibc/unistd.h | 11 +- 2 files changed, 57 insertions(+), 320 deletions(-) -- 2.25.1

[PATCH net 00/14] selftests: mptcp: skip tests not supported by old kernels (part 2)

by Matthieu Baerts

After a few years of increasing test coverage in the MPTCP selftests, we realised [1] the last version of the selftests is supposed to run on old kernels without issues. Supporting older versions is not that easy for this MPTCP case: these selftests are often validating the internals by checking packets that are exchanged, when some MIB counters are incremented after some actions, how connections are getting opened and closed in some cases, etc. In other words, it is not limited to the socket interface between the userspace and the kernelspace. In addition to that, the current MPTCP selftests run a lot of different sub-tests but the TAP13 protocol used in the selftests don't support sub-tests: one failure in sub-tests implies that the whole selftest is seen as failed at the end because sub-tests are not tracked. It is then important to skip sub-tests not supported by old kernels. To minimise the modifications and reduce the complexity to support old versions, the idea is to look at external signs and skip the whole selftests or just some sub-tests before starting them. This cannot be applied in all cases. This second part focuses on marking different sub-tests as skipped if some MPTCP features are not supported. A few techniques are used here: - Before starting some tests: - Check if a file (sysctl knob) is present: that's what patch 13/14 is doing for the userspace PM feature. - Check if a symbol is present in /proc/kallsyms: patch 1/14 adds some helpers in mptcp_lib.sh to ease its use. Then these helpers are used in patches 2, 3, 4, 10, 11 and 14/14. - Set a flag and get the status to check if a feature is supported: patch 8/14 is doing that with the 'fullmesh' flag. - After having launched the tests: - Retrieve the counters after a test and check if they are different than 0. Similar to the check with the flag, that's not ideal but in this case, the counters were already present before the introduction of MPTCP but they have been supported by MPTCP sockets only later. Patches 5 and 6/14 are using this technique. Before skipping tests, SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var value is checked: if it is set to 1, the test is marked as "failed" instead of "skipped". MPTCP public CI expects to have all features supported and it sets this env var to 1 to catch regressions in these new checks. Patches 7/14 and 9/14 are a bit different because they don't skip tests: - Patch 7/14 retrieves the default values instead of using hardcoded ones because these default values have been modified at some points. Then the comparisons are done with the default values. - patch 9/14 relaxes the expected returned size from MPTCP's getsockopt because the different structures gathering various info can get new fields and get bigger over time. We cannot expect that the userspace is using the same structure as the kernel. Patch 12/14 marks the test as "skipped" instead of "failed" if the "ip" tool is not available. In this second part, the "mptcp_join" selftest is not modified yet. This will come soon after in the third part with quite a few patches.

[PATCH bpf v4 0/2] bpf: fix NULL dereference during extable search

by Krister Johansen

Hi, Enclosed are a pair of patches for an oops that can occur if an exception is generated while a bpf subprogram is running. One of the bpf_prog_aux entries for the subprograms are missing an extable. This can lead to an exception that would otherwise be handled turning into a NULL pointer bug. These changes were tested via the verifier and progs selftests and no regressions were observed. Changes from v3: - Selftest style fixups (Feedback from Yonghong Song) - Selftest needs to assert that test bpf program executed (Feedback from Yonghong Song) - Selftest should combine open and load using open_and_load (Feedback from Yonghong Song) Changes from v2: - Insert only the main program's kallsyms (Feedback from Yonghong Song and Alexei Starovoitov) - Selftest should use ASSERT instead of CHECK (Feedback from Yonghong Song) - Selftest needs some cleanup (Feedback from Yonghong Song) - Switch patch order (Feedback from Alexei Starovoitov) Changes from v1: - Add a selftest (Feedback From Alexei Starovoitov) - Move to a 1-line verifier change instead of searching multiple extables Krister Johansen (2): bpf: ensure main program has an extable selftests/bpf: add a test for subprogram extables kernel/bpf/verifier.c | 6 ++- .../bpf/prog_tests/subprogs_extable.c | 29 +++++++++++ .../bpf/progs/test_subprogs_extable.c | 51 +++++++++++++++++++ 3 files changed, 84 insertions(+), 2 deletions(-) create mode 100644 tools/testing/selftests/bpf/prog_tests/subprogs_extable.c create mode 100644 tools/testing/selftests/bpf/progs/test_subprogs_extable.c -- 2.25.1

[PATCH v2 tracing 0/6] tracing: additional filter predicates

by Alan Maguire

For cases like IPv6 addresses, having a means to supply tracing predicates for fields with more than 8 bytes would be convenient. This series provides a simple way to support this by allowing simple ==, != memory comparison with the predicate supplied when the size of the field exceeds 8 bytes. For example, to trace ::1, the predicate "dst == 0x00000000000000000000000000000001" ..could be used. Patch 1 implements this. As a convenience, support for IPv4, IPv6 and MAC addresses are also included; patches 2-4 cover these and allow simpler comparisons which do not require getting the exact number of bytes right; for exmaple "dst == ::1" "src != 127.0.0.1" "mac_addr == ab:cd:ef:01:23:45" Patch 5 adds tests for existing and new filter predicates, and patch 6 documents the fact that for the various addresses supported and the >8 byte memory comparison. only == and != are supported. Changes since v1 [1]: - added support for IPv4, IPv6 and MAC addresses (patches 2-4) (Masami and Steven) - added selftests for IPv4, IPv6 and MAC addresses and updated docs accordingly (patches 5,6) Changes since RFC [2]: - originally a fix was intermixed with the new functionality as patch 1 in series [2]; the fix landed separately - small tweaks to how filter predicates are defined via fn_num as opposed to via fn directly [1] https://lore.kernel.org/linux-trace-kernel/1682414197-13173-1-git-send-emai… [22] https://lore.kernel.org/lkml/1659910883-18223-1-git-send-email-alan.maguire… Alan Maguire (6): tracing: support > 8 byte array filter predicates tracing: support IPv4 address filter predicate tracing: support IPv6 filter predicates tracing: support MAC address filter predicates selftests/ftrace: add test coverage for filter predicates tracing: document IPv4, IPv6, MAC address and > 8 byte numeric filtering support Documentation/trace/events.rst | 21 +++ kernel/trace/trace_events_filter.c | 164 +++++++++++++++++- .../selftests/ftrace/test.d/event/filter.tc | 91 ++++++++++ 3 files changed, 275 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/ftrace/test.d/event/filter.tc -- 2.31.1

[PATCH net v2 0/3] Check if FIPS mode is enabled when running selftests

by Magali Lemes

Some test cases from net/tls, net/fcnal-test and net/vrf-xfrm-tests that rely on cryptographic functions to work and use non-compliant FIPS algorithms fail in FIPS mode. In order to allow these tests to pass in a wider set of kernels, - for net/tls, skip the test variants that use the ChaCha20-Poly1305 and SM4 algorithms, when FIPS mode is enabled; - for net/fcnal-test, skip the MD5 tests, when FIPS mode is enabled; - for net/vrf-xfrm-tests, replace the algorithms that are not FIPS-compliant with compliant ones. Changes in v2: - Add R-b tags. - Put fips_non_compliant into the variants. - Turn fips_enabled into a static global variable. - Read /proc/sys/crypto/fips_enabled only once at main(). v1: https://lore.kernel.org/netdev/20230607174302.19542-1-magali.lemes@canonica… Magali Lemes (3): selftests: net: tls: check if FIPS mode is enabled selftests: net: vrf-xfrm-tests: change authentication and encryption algos selftests: net: fcnal-test: check if FIPS mode is enabled tools/testing/selftests/net/fcnal-test.sh | 27 ++- tools/testing/selftests/net/tls.c | 175 +++++++++++++++++- tools/testing/selftests/net/vrf-xfrm-tests.sh | 32 ++-- 3 files changed, 209 insertions(+), 25 deletions(-) -- 2.34.1

[PATCH] selftests/cpufreq: Don't enable generic lock debugging options

by Mark Brown

Currently the the config fragment for cpufreq enables a lot of generic lock debugging. While these options are useful when testing cpufreq they aren't actually required to run the tests and are therefore out of scope for the cpufreq fragement, they are more of a thing that it's good to enable while doing testing than an actual requirement for cpufreq testing specifically. Having these debugging options enabled, especially the mutex and spinlock instrumentation, mean that any build that includes the cpufreq fragment is both very much larger than a standard defconfig (eg, I'm seeing 35% on x86_64) and also slower at runtime. This is causing real problems for CI systems. In order to avoid building large numbers of kernels they try to group kselftest fragments together, frequently just grouping all the kselftest fragments into a single block. The increased size is an issue for memory constrained systems and is also problematic for systems with fixed storage allocations for kernel images (eg, typical u-boot systems) where it frequently causes the kernel to overflow the storage space allocated for kernels. The reduced performance isn't too bad with real hardware but can be disruptive on emulated platforms. In order to avoid these issues remove these generic instrumentation options from the cpufreq fragment, bringing the cpufreq fragment into line with other fragments which generally set requirements for testing rather than nice to haves.

[PATCH v2] HID: uclogic: Modular KUnit tests should not depend on KUNIT=y

by Geert Uytterhoeven

While KUnit tests that cannot be built as a loadable module must depend on "KUNIT=y", this is not true for modular tests, where it adds an unnecessary limitation. Fix this by relaxing the dependency to "KUNIT".

[RFC PATCH] asm-generic: Unify uapi bitsperlong.h

by Tiezhu Yang

Now we specify the minimal version of GCC as 5.1 and Clang/LLVM as 11.0.0 in Documentation/process/changes.rst, __CHAR_BIT__ and __SIZEOF_LONG__ are usable, just define __BITS_PER_LONG as (__CHAR_BIT__ * __SIZEOF_LONG__) in asm-generic uapi bitsperlong.h, simpler, works everywhere.

[PATCH bpf-next v3 0/3] bpf, x86: allow function arguments up to 12 for TRACING

by menglong8.dong＠gmail.com

From: Menglong Dong <imagedong(a)tencent.com> For now, the BPF program of type BPF_PROG_TYPE_TRACING can only be used on the kernel functions whose arguments count less than 6. This is not friendly at all, as too many functions have arguments count more than 6. Therefore, let's enhance it by increasing the function arguments count allowed in arch_prepare_bpf_trampoline(), for now, only x86_64. In the 1st patch, we make arch_prepare_bpf_trampoline() support to copy function arguments in stack for x86 arch. Therefore, the maximum arguments can be up to MAX_BPF_FUNC_ARGS for FENTRY and FEXIT. In the 2nd patch, we clean garbage value in upper bytes of the trampoline when we store the arguments from regs into stack. And the 3rd patches are for the testcases of the 1st patch. Changes since v2: - keep MAX_BPF_FUNC_ARGS still - clean garbage value in upper bytes in the 2nd patch - move bpf_fentry_test{7,12} to bpf_testmod.c and rename them to bpf_testmod_fentry_test{7,12} meanwhile in the 3rd patch Changes since v1: - change the maximun function arguments to 14 from 12 - add testcases (Jiri Olsa) - instead EMIT4 with EMIT3_off32 for "lea" to prevent overflow Menglong Dong (3): bpf, x86: allow function arguments up to 12 for TRACING bpf, x86: clean garbage value in the stack of trampoline selftests/bpf: add testcase for FENTRY/FEXIT with 6+ arguments arch/x86/net/bpf_jit_comp.c | 105 +++++++++++++++--- .../selftests/bpf/bpf_testmod/bpf_testmod.c | 19 +++- .../selftests/bpf/prog_tests/fentry_fexit.c | 4 +- .../selftests/bpf/prog_tests/fentry_test.c | 2 + .../selftests/bpf/prog_tests/fexit_test.c | 2 + .../testing/selftests/bpf/progs/fentry_test.c | 21 ++++ .../testing/selftests/bpf/progs/fexit_test.c | 33 ++++++ 7 files changed, 169 insertions(+), 17 deletions(-) -- 2.40.1

[PATCH net 0/3] Check if FIPS mode is enabled when running selftests

by Magali Lemes

Some test cases from net/tls, net/fcnal-test and net/vrf-xfrm-tests that rely on cryptographic functions to work and use non-compliant FIPS algorithms fail in FIPS mode. In order to allow these tests to pass in a wider set of kernels, - for net/tls, skip the test variants that use the ChaCha20-Poly1305 and SM4 algorithms, when FIPS mode is enabled; - for net/fcnal-test, skip the MD5 tests, when FIPS mode is enabled; - for net/vrf-xfrm-tests, replace the algorithms that are not FIPS-compliant with compliant ones.

[PATCH v2 00/11] RISCV: Add KVM_GET_REG_LIST API

by Haibo Xu

KVM_GET_REG_LIST will dump all register IDs that are available to KVM_GET/SET_ONE_REG and It's very useful to identify some platform regression issue during VM migration. Patch 1-7 re-structured the get-reg-list test in aarch64 to make some of the code as common test framework that can be shared by riscv. Patch 8 enabled the KVM_GET_REG_LIST API in riscv and patch 9-11 added the corresponding kselftest for checking possible register regressions. The get-reg-list kvm selftest was ported from aarch64 and tested with Linux 6.4-rc1 on a Qemu riscv virt machine. --- Changed since v1: * rebase to Andrew's changes * fix coding style Andrew Jones (7): KVM: arm64: selftests: Replace str_with_index with strdup_printf KVM: arm64: selftests: Drop SVE cap check in print_reg KVM: arm64: selftests: Remove print_reg's dependency on vcpu_config KVM: arm64: selftests: Rename vcpu_config and add to kvm_util.h KVM: arm64: selftests: Delete core_reg_fixup KVM: arm64: selftests: Split get-reg-list test code KVM: arm64: selftests: Finish generalizing get-reg-list Haibo Xu (4): KVM: riscv: Add KVM_GET_REG_LIST API support KVM: riscv: selftests: Make check_supported arch specific KVM: riscv: selftests: Skip some registers set operation KVM: riscv: selftests: Add get-reg-list test Documentation/virt/kvm/api.rst | 2 +- arch/riscv/kvm/vcpu.c | 372 ++++++++++++ tools/testing/selftests/kvm/Makefile | 13 +- .../selftests/kvm/aarch64/get-reg-list.c | 540 ++---------------- tools/testing/selftests/kvm/get-reg-list.c | 426 ++++++++++++++ .../selftests/kvm/include/kvm_util_base.h | 16 + .../selftests/kvm/include/riscv/processor.h | 3 + .../testing/selftests/kvm/include/test_util.h | 2 + tools/testing/selftests/kvm/lib/test_util.c | 15 + .../selftests/kvm/riscv/get-reg-list.c | 539 +++++++++++++++++ 10 files changed, 1428 insertions(+), 500 deletions(-) create mode 100644 tools/testing/selftests/kvm/get-reg-list.c create mode 100644 tools/testing/selftests/kvm/riscv/get-reg-list.c -- 2.34.1

[PATCH bpf v2 0/2] bpf: fix NULL dereference during extable search

by Krister Johansen

Hi, Enclosed are a pair of patches for an oops that can occur if an exception is generated while a bpf subprogram is running. One of the bpf_prog_aux entries for the subprograms are missing an extable. This can lead to an exception that would otherwise be handled turning into a NULL pointer bug. The bulk of the change here is simply adding a pair of programs for the selftest. The proposed fix in this iteration is a 1-line change. These changes were tested via the verifier and progs selftests and no regressions were observed. Changes from v1: - Add a selftest (Feedback From Alexei Starovoitov) - Move to a 1-line verifier change instead of searching multiple extables Krister Johansen (2): Add a selftest for subprogram extables bpf: ensure main program has an extable kernel/bpf/verifier.c | 1 + .../bpf/prog_tests/subprogs_extable.c | 35 +++++++++ .../bpf/progs/test_subprogs_extable.c | 71 +++++++++++++++++++ 3 files changed, 107 insertions(+) create mode 100644 tools/testing/selftests/bpf/prog_tests/subprogs_extable.c create mode 100644 tools/testing/selftests/bpf/progs/test_subprogs_extable.c -- 2.25.1

[PATCH v2 00/16] Use MMU read lock for clear-dirty-log

by Vipin Sharma

Hi, This series is on top of kvmarm/next as I needed to also modify Eager page splitting logic in clear-dirty-log API. Eager page splitting is not present in Linux 6.4-rc4. Also, I had to change selftests patches (1 to 5) as some commits were removed from kvm/queue remote. This caused issue due to different APIs being present in dirty_log_perf_test when I was rebasing v2. Those removed commits are now back in kvm-x86 branch of Sean [1] but not in kvmarm/next or kvm/queue. I didn't want to wait for review of v2, so I changed dirty_log_perf_test to work with kvmarm/next branch. When Sean's kvm-x86 branch is merged, sleftests in this patch series need to be modified to use new APIs or whoever merges last need to take care of that. This patch series modifies clear-dirty-log operation to run under MMU read lock. It write protects SPTEs and split huge pages using MMU read lock instead of MMU write lock. Use of MMU read lock is made possible by using shared page table walkers. Currently only page fault handlers use shared page table walkers, with this series, clear-dirty-log operation will also use shared page table walkers. Patches 1 to 5: These patches are modifying dirty_log_perf_test. Intent is to mimic production scenarios where guest keeps on executing while userspace thread collects and clears dirty logs independently. Three new command line options are added: 1. j: Allows to run guest vCPUs and main thread collecting dirty logs independently of each other after initialization is complete. 2. k: Allows to clear dirty logs in smaller chunks compared to existing whole memslot clear in one call. 3. l: Allows to add customizable wait time between consecutive clear dirty log calls to mimic sending dirty memory to destination. Patch 7-16: These patches refactor code to move MMU lock operations to arch specific code, refactor Arm's page table walker APIs, and change MMU write lock for clearing dirty logs to read lock. Patch 16 has results showing improvements based on dirty_log_perf_test. 1. https://lore.kernel.org/lkml/168565341087.666819.6731422637224460050.b4-ty@… v2: - Fix compile warning for mips and riscv. - Added logic to continue or retry shared page walk which are not fault handler. - Huge page split also changed to run under MMU read lock. - Added more explanations in commit logs. - Selftests is modified because a commit series was reverted back in dirty_log_perf_test on kvm/queue. v1: https://lore.kernel.org/lkml/20230421165305.804301-1-vipinsh@google.com/ Vipin Sharma (16): KVM: selftests: Clear dirty logs in user defined chunks sizes in dirty_log_perf_test KVM: selftests: Add optional delay between consecutive clear-dirty-log calls KVM: selftests: Pass the count of read and write accesses from guest to host KVM: selftests: Print read-write progress by vCPUs in dirty_log_perf_test KVM: selftests: Allow independent execution of vCPUs in dirty_log_perf_test KVM: arm64: Correct the kvm_pgtable_stage2_flush() documentation KVM: mmu: Move mmu lock/unlock to arch code for clear dirty log KMV: arm64: Pass page table walker flags to stage2_apply_range_*() KVM: arm64: Document the page table walker actions based on the callback's return value KVM: arm64: Return -ENOENT if PTE is not valid in stage2_attr_walker KVM: arm64: Use KVM_PGTABLE_WALK_SHARED flag instead of KVM_PGTABLE_WALK_HANDLE_FAULT KVM: arm64: Retry shared page table walks outside of fault handler KVM: arm64: Run clear-dirty-log under MMU read lock KVM: arm64: Pass page walker flags from callers of stage 2 split walker KVM: arm64: Provide option to pass page walker flag for huge page splits KVM: arm64: Split huge pages during clear-dirty-log under MMU read lock arch/arm64/include/asm/kvm_pgtable.h | 42 +++-- arch/arm64/kvm/hyp/nvhe/mem_protect.c | 4 +- arch/arm64/kvm/hyp/pgtable.c | 68 ++++++-- arch/arm64/kvm/mmu.c | 65 +++++--- arch/mips/kvm/mmu.c | 2 + arch/riscv/kvm/mmu.c | 2 + arch/x86/kvm/mmu/mmu.c | 3 + .../selftests/kvm/dirty_log_perf_test.c | 147 ++++++++++++++---- tools/testing/selftests/kvm/lib/memstress.c | 13 +- virt/kvm/dirty_ring.c | 2 - virt/kvm/kvm_main.c | 4 - 11 files changed, 265 insertions(+), 87 deletions(-) base-commit: 532b2ecfa547f02b1825108711565eff026bce5a -- 2.41.0.rc0.172.g3f132b7071-goog

nolibc patches, still possible for 6.5 ?

by Willy Tarreau

Hello Paul, Thomas and Zhangjin have provided significant nolibc cleanups, and fixes, as well as preparation work to later support riscv32. These consist in the following main series: - generalization of stackprotector to other archs that were not previously supported (riscv, mips, loongarch, arm, arm64) - general cleanups of the makefile, test report output, deduplication of certain tests - slightly better compliance of some tests performed on certain syscalls (e.g. no longer pass (void*)1 to gettimeofday() since glibc hates it). - add support for nanoseconds in stat() and statx() - fixes for some syscalls (e.g. ppoll() has 5 arguments not 4) - fixes around limits.h and INT_MAX / INT_FAST64_MAX I rebased the whole series on top of your latest dev branch (d19a9ca3d5) and it works fine for all archs. I don't know if you're still planning on merging new stuff in this area for 6.5 or not (since I know that it involves new series of tests on your side as well), but given that Zhangjin will engage into deeper changes later for riscv32 that will likely imply to update more syscalls to use the time64 ones, I would prefer to split the cleanups from the hard stuff, but I'll let you judge based on the current state of what's pending for 6.5. In any case I'm putting all this here for now (not for merge yet): git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/nolibc.git 20230604-nolibc-rv32+stkp6 I'd like Thomas and Zhangjin to perform a last check to confirm they're OK with this final integration. Thanks! Willy

[PATCH 1/2] tty: tty_io: update timestamps on all device nodes

by Michal Sekletar

User space applications watch for timestamp changes on character device files in order to determine idle time of a given terminal session. For example, "w" program uses this information to populate the IDLE column of its output [1]. Similarly, systemd-logind has optional feature where it uses atime of the tty character device to determine if there was activity on the terminal associated with the logind's session object. If there was no activity for a configured period of time then logind will terminate such session [2]. Now, usually (e.g. bash running on the terminal) the use of the terminal will update timestamps (atime and mtime) on the corresponding terminal character device. However, if access to the terminal, e.g. /dev/pts/0, is performed through magic character device /dev/tty then such access obviously changes the state of the terminal, however timestamps on the device that correspond to the terminal (/dev/pts/0) are not updated. This patch makes sure that we update timestamps on *all* character devices that correspond to the given tty, because outside observers (w, systemd-logind) are maybe checking these timestamps. Obviously, they can not check timestamps on /dev/tty as that has per-process meaning.

[PATCH bpf v4 0/2] Fix verifier id tracking of scalars on spill

by Maxim Mikityanskiy

From: Maxim Mikityanskiy <maxim(a)isovalent.com> See the details in the commit message (TL/DR: under CAP_BPF, the verifier can incorrectly conclude that a scalar is zero while in fact it can be crafted to a predefined number.) v1 and v2 were sent off-list. v2 changes: Added more tests, migrated them to inline asm, started using bpf_get_prandom_u32, switched to a more bulletproof dead branch check and modified the failing spill test scenarios so that an unauthorized access attempt is performed in both branches. v3 changes: Dropped an improvement not necessary for the fix, changed the Fixes tag. v4 changes: Dropped supposedly redundant tests, kept the ones that result in different verifier verdicts. Dropped the variable that is not yet useful in this patch. Rephrased the commit message with Daniel's suggestions.

[PATCH v3 0/3] tools/nolibc: add a new syscall helper

by Zhangjin Wu

Willy, Thomas This is the revision of the v2 syscall helpers [1], it is based on 20230606-nolibc-rv32+stkp7a of [2]. It doesn't conflict with the v4 of -ENOSYS patchset [3], so, it is ok to simply merge both of them. This revision mainly applied Thomas' method, removed the __syscall() helper and replaced it with __sysret() instead, because __syscall() looks like _syscall() and syscall(), it may mixlead the developers. Changes from v2 -> v3: * tools/nolibc: sys.h: add a syscall return helper * The __syscall() is removed. * Align the code style of __sysret() with the others, and use __inline__ instead of inline (like stdlib.h) to let it work with the default -std=c89 in tools/testing/selftests/nolibc/Makefile * tools/nolibc: unistd.h: apply __sysret() helper As v2. * tools/nolibc: sys.h: apply __sysret() helper replaced __syscall() with __sysret() and merged two separated patches of v2 to one. Did run-user tests for rv32 (with [3]), rv64 and arm64. BTW, two questions for Thomas, * This commit 659a49abc9c2 ("tools/nolibc: validate C89 compatibility") enables -std=c89, why not gnu11 used by kernel ? ;-) * Do we need to tune the order of the macros in unistd.h like this: #define _syscall(N, ...) __sysret(my_syscall##N(__VA_ARGS__)) #define _syscall_n(N, ...) _syscall(N, __VA_ARGS__) #define __syscall_narg(_0, _1, _2, _3, _4, _5, _6, N, ...) N #define _sycall_narg(...) __syscall_narg(__VA_ARGS__, 6, 5, 4, 3, 2, 1, 0) #define syscall(...) _syscall_n(_sycall_narg(__VA_ARGS__), ##__VA_ARGS__) Before, It works but seems not put in using order: #define _syscall(N, ...) __sysret(my_syscall##N(__VA_ARGS__)) #define _sycall_narg(...) __syscall_narg(__VA_ARGS__, 6, 5, 4, 3, 2, 1, 0) #define __syscall_narg(_0, _1, _2, _3, _4, _5, _6, N, ...)

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 RESEND 0/2] drivers: base: Add tests showing devm handling inconsistencies

by Maxime Ripard

Hi, This follows the discussion here: https://lore.kernel.org/linux-kselftest/20230324123157.bbwvfq4gsxnlnfwb@hou… This shows a couple of inconsistencies with regard to how device-managed resources are cleaned up. Basically, devm resources will only be cleaned up if the device is attached to a bus and bound to a driver. Failing any of these cases, a call to device_unregister will not end up in the devm resources being released. We had to work around it in DRM to provide helpers to create a device for kunit tests, but the current discussion around creating similar, generic, helpers for kunit resumed interest in fixing this. This can be tested using the command: ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/base/test/ Let me know what you think, Maxime Signed-off-by: Maxime Ripard <maxime(a)cerno.tech> --- Maxime Ripard (2): drivers: base: Add basic devm tests for root devices drivers: base: Add basic devm tests for platform devices drivers/base/test/.kunitconfig | 2 + drivers/base/test/Kconfig | 4 + drivers/base/test/Makefile | 3 + drivers/base/test/platform-device-test.c | 278 +++++++++++++++++++++++++++++++ drivers/base/test/root-device-test.c | 120 +++++++++++++ 5 files changed, 407 insertions(+) --- base-commit: a6faf7ea9fcb7267d06116d4188947f26e00e57e change-id: 20230329-kunit-devm-inconsistencies-test-5e5a7d01e60d Best regards, -- Maxime Ripard <mripard(a)kernel.org>
