[PATCH v5 linux-kselftest-test 0/6] kunit: support building core/tests as modules

by Alan Maguire

The current kunit execution model is to provide base kunit functionality and tests built-in to the kernel. The aim of this series is to allow building kunit itself and tests as modules. This in turn allows a simple form of selective execution; load the module you wish to test. In doing so, kunit itself (if also built as a module) will be loaded as an implicit dependency. Because this requires a core API modification - if a module delivers multiple suites, they must be declared with the kunit_test_suites() macro - we're proposing this patch set as a candidate to be applied to the test tree before too many kunit consumers appear. We attempt to deal with existing consumers in patch 3. Changes since v4: - fixed signoff chain to use Co-developed-by: prior to Knut's signoff (Stephen, all patches) - added Reviewed-by, Tested-by for patches 1, 2, 4 and 6 - updated comment describing try-catch-impl.h (Stephen, patch 2) - fixed MODULE_LICENSEs to be GPL v2 (Stephen, patches 3, 5) - added __init to kunit_init() (Stephen, patch 5) Changes since v3: - removed symbol lookup patch for separate submission later - removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed with Brendan and Stephen) - disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this is to avoid having to deal with symbol lookup issues - changed string-stream-impl.h back to string-stream.h (Brendan) - added module build support to new list, ext4 tests Changes since v2: - moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan) (patch 1) - split out non-exported interfaces in try-catch-impl.h (Brendan) (patch 2) - added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported symbols (patches 3, 4) - removed #ifdef MODULE around module licenses (Randy, Brendan, Andy) (patch 4) - replaced kunit_test_suite() with kunit_test_suites() rather than supporting both (Brendan) (patch 4) - lookup sysctl_hung_task_timeout_secs as kunit may be built as a module and the symbol may not be available (patch 5) Alan Maguire (6): kunit: move string-stream.h to lib/kunit kunit: hide unexported try-catch interface in try-catch-impl.h kunit: allow kunit tests to be loaded as a module kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds kunit: allow kunit to be loaded as a module kunit: update documentation to describe module-based build Documentation/dev-tools/kunit/faq.rst | 3 +- Documentation/dev-tools/kunit/index.rst | 3 ++ Documentation/dev-tools/kunit/usage.rst | 16 ++++++++++ fs/ext4/Kconfig | 2 +- fs/ext4/Makefile | 5 +++ fs/ext4/inode-test.c | 4 ++- include/kunit/assert.h | 3 +- include/kunit/test.h | 35 ++++++++++++++------ include/kunit/try-catch.h | 10 ------ kernel/sysctl-test.c | 4 ++- lib/Kconfig.debug | 4 +-- lib/kunit/Kconfig | 6 ++-- lib/kunit/Makefile | 14 +++++--- lib/kunit/assert.c | 10 ++++++ lib/kunit/{example-test.c => kunit-example-test.c} | 4 ++- lib/kunit/{test-test.c => kunit-test.c} | 7 ++-- lib/kunit/string-stream-test.c | 5 +-- lib/kunit/string-stream.c | 3 +- {include => lib}/kunit/string-stream.h | 0 lib/kunit/test.c | 25 ++++++++++++++- lib/kunit/try-catch-impl.h | 27 ++++++++++++++++ lib/kunit/try-catch.c | 37 +++++----------------- lib/list-test.c | 4 ++- 23 files changed, 160 insertions(+), 71 deletions(-) rename lib/kunit/{example-test.c => kunit-example-test.c} (97%) rename lib/kunit/{test-test.c => kunit-test.c} (98%) rename {include => lib}/kunit/string-stream.h (100%) create mode 100644 lib/kunit/try-catch-impl.h -- 1.8.3.1

selftests: l2tp tests

by Colin Ian King

Hi, While testing linux 5.4 with the l2tp test I discovered two kernel issues when running this test: 1. About 10+ seconds after completing the test one can observe periodic kernel log messages from netdev_wait_allrefs (in net/core/dev.c) in the form: "unregister_netdevice: waiting for eth0 to become free. Usage count = 1" 2. Our regression tests that ran stress-ng after this test picked up another issue that causes socket() to hang indefinitely. I've managed to get this down to a simple reproducer as follows: sudo modprobe l2tp_core sudo ./linux/tools/testing/selftests/net/l2tp.sh sleep 5 ./close Where ./close is an executable compiled from: #include <sys/types.h> #include <sys/socket.h> #include <unistd.h> #include <stdio.h> int main() { int fd; printf("calling socket..\n"); fd = socket(AF_APPLETALK, SOCK_STREAM, 0); printf("socket returned: %d\n", fd); } The code will hang on the socket() call and won't ever get to the final print statement. If one runs the reproducer on earlier kernels we get: 4.6.7 crash (see dmesg below) 4.7.10 crash in xfrm6_dst_ifdown 4.8.17 crash in xfrm6_dst_ifdown 4.12.14 crash (see dmesg below) 4.13.16 reports "unregister_netdevice: waiting for eth0 to become free. Usage count = 2" 4.14.157 reports "unregister_netdevice: waiting for eth0 to become free. Usage count = 2"" 4.15.18 .. 5.4 hangs on socket() call Note: functionality for the l2tp test is not available for pre-4.6 kernels. The crashes I get for older kernels are: 4.6.7: [ 34.457967] BUG: scheduling while atomic: kworker/u8:0/6/0x00000200 [ 34.458021] Modules linked in: esp6 xfrm6_mode_transport drbg ansi_cprng seqiv esp4 xfrm4_mode_transport xfrm_user xfrm_algo l2tp_ip6 l2tp_eth l2tp_ip l2tp_netlink veth l2tp_core ip6_udp_tunnel udp_tunnel squashfs binfmt_misc dm_multipath scsi_dh_rdac scsi_dh_emc scsi_dh_alua ppdev kvm_intel kvm irqbypass joydev input_leds snd_hda_codec_generic serio_raw snd_hda_intel snd_hda_codec parport_pc 8250_fintek parport snd_hda_core qemu_fw_cfg snd_hwdep snd_pcm snd_timer mac_hid snd soundcore sch_fq_codel virtio_rng ip_tables x_tables autofs4 btrfs raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor hid_generic usbhid hid raid6_pq libcrc32c raid1 raid0 multipath linear crct10dif_pclmul crc32_pclmul ghash_clmulni_intel qxl ttm drm_kms_helper syscopyarea sysfillrect aesni_intel sysimgblt [ 34.458086] fb_sys_fops aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd i2c_piix4 drm psmouse pata_acpi floppy [ 34.458100] CPU: 1 PID: 6 Comm: kworker/u8:0 Not tainted 4.6.7-040607-generic #201608160432 [ 34.458103] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 [ 34.458131] Workqueue: netns cleanup_net [ 34.458135] 0000000000000286 000000002fa171e7 ffff88007c8e7ab8 ffffffff813f7594 [ 34.458139] ffff88007fc96b80 7fffffffffffffff ffff88007c8e7ac8 ffffffff810a8f6b [ 34.458143] ffff88007c8e7b18 ffffffff8184905b 00ff88007c8e7ae8 ffffffff8106463e [ 34.458147] Call Trace: [ 34.458161] [<ffffffff813f7594>] dump_stack+0x63/0x8f [ 34.458166] [<ffffffff810a8f6b>] __schedule_bug+0x4b/0x60 [ 34.458185] [<ffffffff8184905b>] __schedule+0x5eb/0x7a0 [ 34.458191] [<ffffffff8106463e>] ? kvm_sched_clock_read+0x1e/0x30 [ 34.458195] [<ffffffff81849245>] schedule+0x35/0x80 [ 34.458203] [<ffffffff8184c402>] schedule_timeout+0x1b2/0x270 [ 34.458207] [<ffffffff81848d74>] ? __schedule+0x304/0x7a0 [ 34.458212] [<ffffffff81849ca3>] wait_for_completion+0xb3/0x140 [ 34.458217] [<ffffffff810aeed0>] ? wake_up_q+0x70/0x70 [ 34.458226] [<ffffffff810e7f68>] __wait_rcu_gp+0xc8/0xf0 [ 34.458231] [<ffffffff810e9fd8>] synchronize_sched.part.58+0x38/0x50 [ 34.458235] [<ffffffff810ec570>] ? call_rcu_bh+0x20/0x20 [ 34.458239] [<ffffffff810e7e80>] ? trace_raw_output_rcu_utilization+0x60/0x60 [ 34.458244] [<ffffffff810ec643>] synchronize_sched+0x33/0x40 [ 34.458251] [<ffffffffc0510f71>] __l2tp_session_unhash+0xd1/0xe0 [l2tp_core] [ 34.458256] [<ffffffffc051101e>] l2tp_tunnel_closeall+0x9e/0x140 [l2tp_core] [ 34.458261] [<ffffffffc0511219>] l2tp_tunnel_delete+0x19/0x70 [l2tp_core] [ 34.458265] [<ffffffffc05112bb>] l2tp_exit_net+0x4b/0x80 [l2tp_core] [ 34.458269] [<ffffffff81732188>] ops_exit_list.isra.4+0x38/0x60 [ 34.458273] [<ffffffff817331e4>] cleanup_net+0x1c4/0x2a0 [ 34.458281] [<ffffffff8109ccfc>] process_one_work+0x1fc/0x490 [ 34.458285] [<ffffffff8109cfdb>] worker_thread+0x4b/0x500 [ 34.458290] [<ffffffff8109cf90>] ? process_one_work+0x490/0x490 [ 34.458293] [<ffffffff810a37c8>] kthread+0xd8/0xf0 [ 34.458298] [<ffffffff8184d522>] ret_from_fork+0x22/0x40 [ 34.458302] [<ffffffff810a36f0>] ? kthread_create_on_node+0x1b0/0x1b0 [ 34.514067] ------------[ cut here ]------------ 4.12.14: [ 20.760253] ------------[ cut here ]------------ [ 20.760256] kernel BUG at /home/kernel/COD/linux/net/ipv6/xfrm6_policy.c:265!

[PATCH v7 00/25] Unify vDSOs across more architectures

by Vincenzo Frascino

vDSO (virtual dynamic shared object) is a mechanism that the Linux kernel provides as an alternative to system calls to reduce where possible the costs in terms of cycles. This is possible because certain syscalls like gettimeofday() do not write any data and return one or more values that are stored in the kernel, which makes relatively safe calling them directly as a library function. Even if the mechanism is pretty much standard, every architecture in the last few years ended up implementing their own vDSO library in the architectural code. The purpose of this patch-set is to identify the commonalities in between the architectures and try to consolidate the common code paths, starting with gettimeofday(). This implementation contains the following design choices: * Every architecture defines the arch specific code in an header in "asm/vdso/". * The generic implementation includes the arch specific one and lives in "lib/vdso". * The arch specific code for gettimeofday lives in "<arch path>/vdso/gettimeofday.c" and includes the generic code only. * The generic implementation of update_vsyscall and update_vsyscall_tz lives in kernel/vdso and provide the bindings that can be implemented by each architecture. * Each architecture provides its implementation of the bindings in "asm/vdso/vsyscall.h". * This approach allows to consolidate the common code in a single place with the benefit of avoiding code duplication. This implementation contains the portings to the common library for: arm64, compat mode for arm64, arm, mips, x86_64, x32, compat mode for x86_64 and i386. The mips porting has been tested on qemu for mips32el. A configuration to repeat the tests can be found at [4]. The x86_64 porting has been tested on an Intel Xeon 5120T based machine running Ubuntu 18.04 and using the Ubuntu provided defconfig. The i386 porting has been tested on qemu using the i386_defconfig configuration. Last but not least from this porting arm64, compat arm64, arm and mips gain the support for: * CLOCK_BOOTTIME that can be useful in certain scenarios since it keeps track of the time during sleep as well. * CLOCK_TAI that is like CLOCK_REALTIME, but uses the International Atomic Time (TAI) reference instead of UTC to avoid jumping on leap second updates. for both clock_gettime and clock_getres. The porting has been validated using the vdsotest test-suite [1] extended to cover all the clock ids [2]. A new test has been added to the linux kselftest in order to validate the newly added library. The porting has been benchmarked and the performance results are provided as part of this cover letter. To simplify the testing, a copy of the patchset on top of a recent linux tree can be found at [3] and [4]. The v7 of this patchseries has been rebased on [5].

[BUGFIX PATCH] selftests/x86: Check the availablity of sys/syscall.h

by Masami Hiramatsu

Since single_step_syscall.c depends on sys/syscall.h and its include, asm/unistd.h, we should check the availability of those headers. Without this fix, if gcc-multilib is not installed but libc6-dev-i386 is installed, kselftest tries to build 32bit binary and failed with following error message. In file included from single_step_syscall.c:18: /usr/include/sys/syscall.h:24:10: fatal error: asm/unistd.h: No such file or directory #include <asm/unistd.h> ^~~~~~~~~~~~~~ compilation terminated.

[PATCH kselftest-next 1/2] kselftests: memcg: update the oom group leaf events test

by Roman Gushchin

Commit 9852ae3fe529 ("mm, memcg: consider subtrees in memory.events") made memory.events recursive: all events are propagated upwards by the tree. It was a change in semantics. It broke the oom group leaf events test: it assumes that after an OOM the oom_kill counter is zero on parent's level. Let's adjust the test: it should have similar expectations for the child and parent levels. The test passes after this fix.

[PATCH v4 0/4] PM / QoS: Restore DEV_PM_QOS_MIN/MAX_FREQUENCY

by Leonard Crestez

Support for frequency limits in dev_pm_qos was removed when cpufreq was switched to freq_qos, this series attempts to restore it by reimplementing on top of freq_qos. Discussion about removal is here: https://lore.kernel.org/linux-pm/VI1PR04MB7023DF47D046AEADB4E051EBEE680@VI1… The cpufreq core switched away because it needs contraints at the level of a "cpufreq_policy" which cover multiple cpus so dev_pm_qos coupling to struct device was not useful. Cpufreq could only use dev_pm_qos by implementing an additional layer of aggregation anyway. However in the devfreq subsystem scaling is always performed on a per-device basis so dev_pm_qos is a very good match. Support for dev_pm_qos in devfreq core is here (latest version, no dependencies outside this series): https://patchwork.kernel.org/cover/11252409/ That series is RFC mostly because it needs these PM core patches. Earlier versions got entangled in some locking cleanups but those are not strictly necessary to get dev_pm_qos functionality. In theory if freq_qos is extended to handle conflicting min/max values then this sharing would be valuable. Right now freq_qos just ties two unrelated pm_qos aggregations for min and max freq. --- This is implemented by embeding a freq_qos_request inside dev_pm_qos_request: the data field was already an union in order to deal with flag requests. The internal freq_qos_apply is exported so that it can be called from dev_pm_qos apply_constraints. The dev_pm_qos_constraints_destroy function has no obvious equivalent in freq_qos and the whole approach of "removing requests" is somewhat dubios: request objects should be owned by consumers and the list of qos requests will most likely be empty when the target device is deleted. Series follows current pattern for dev_pm_qos. First two patches can be applied separately. Changes since v3: * Fix s/QOS/QoS in patch 2 title * Improves comments in kunit test * Fix assertions after freq_qos_remove_request * Remove (c) from NXP copyright header * Wrap long lines in qos.c to be under 80 chars. This fixes checkpatch but the rule is already broken by code in the files. * Collect reviews Link to v3: https://patchwork.kernel.org/cover/11260627/ Changes since v2: * #define PM_QOS_MAX_FREQUENCY_DEFAULT_VALUE FREQ_QOS_MAX_DEFAULT_VALUE * #define FREQ_QOS_MAX_DEFAULT_VALUE S32_MAX (in new patch) * Add initial kunit test for freq_qos, validating the MAX_DEFAULT_VALUE found by Matthias and another recent fix. Testing this should be easier! Link to v2: https://patchwork.kernel.org/cover/11250413/ Changes since v1: * Don't rename or EXPORT_SYMBOL_GPL the freq_qos_apply function; just drop the static marker.

[PATCH] fs/ext4/inode-test: Fix inode test on 32 bit platforms.

by Iurii Zaikin

Fixes the issue caused by the fact that in C in the expression of the form -1234L only 1234L is the actual literal, the unary minus is an operation applied to the literal. Which means that to express the lower bound for the type one has to negate the upper bound and subtract 1. Original error: Expected test_data[i].expected.tv_sec == timestamp.tv_sec, but test_data[i].expected.tv_sec == -2147483648 timestamp.tv_sec == 2147483648 1901-12-13 Lower bound of 32bit < 0 timestamp, no extra bits: msb:1 lower_bound:1 extra_bits: 0 Expected test_data[i].expected.tv_sec == timestamp.tv_sec, but test_data[i].expected.tv_sec == 2147483648 timestamp.tv_sec == 6442450944 2038-01-19 Lower bound of 32bit <0 timestamp, lo extra sec bit on: msb:1 lower_bound:1 extra_bits: 1 Expected test_data[i].expected.tv_sec == timestamp.tv_sec, but test_data[i].expected.tv_sec == 6442450944 timestamp.tv_sec == 10737418240 2174-02-25 Lower bound of 32bit <0 timestamp, hi extra sec bit on: msb:1 lower_bound:1 extra_bits: 2 not ok 1 - inode_test_xtimestamp_decoding not ok 1 - ext4_inode_test Reported-by: Geert Uytterhoeven <geert(a)linux-m68k.org> Signed-off-by: Iurii Zaikin <yzaikin(a)google.com> Tested-by: Geert Uytterhoeven <geert(a)linux-m68k.org> --- fs/ext4/inode-test.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/ext4/inode-test.c b/fs/ext4/inode-test.c index 92a9da1774aa..bbce1c328d85 100644 --- a/fs/ext4/inode-test.c +++ b/fs/ext4/inode-test.c @@ -25,7 +25,7 @@ * For constructing the negative timestamp lower bound value. * binary: 10000000 00000000 00000000 00000000 */ -#define LOWER_MSB_1 (-0x80000000L) +#define LOWER_MSB_1 (-(UPPER_MSB_0) - 1L) /* avoid overflow */ /* * For constructing the negative timestamp upper bound value. * binary: 11111111 11111111 11111111 11111111 -- 2.24.0.432.g9d3f5f5b63-goog

[GIT PULL] seccomp updates for v5.5-rc1

by Kees Cook

Hi Linus, Please pull these seccomp updates for v5.5-rc1. Mostly this is implementing the new flag SECCOMP_USER_NOTIF_FLAG_CONTINUE, but there are cleanups as well. Most notably, the secure_computing() prototype has changed (to remove an unused argument), but this has happened at the same time as riscv adding seccomp support, so the cleanest merge order would be to merge riscv first, then seccomp with the following patch for riscv to handle the change from "seccomp: simplify secure_computing()": diff --git a/arch/riscv/kernel/ptrace.c b/arch/riscv/kernel/ptrace.c index 0f84628b9385..407464201b91 100644 --- a/arch/riscv/kernel/ptrace.c +++ b/arch/riscv/kernel/ptrace.c @@ -159,7 +159,7 @@ __visible void do_syscall_trace_enter(struct pt_regs *regs) * If this fails we might have return value in a0 from seccomp * (via SECCOMP_RET_ERRNO/TRACE). */ - if (secure_computing(NULL) == -1) { + if (secure_computing() == -1) { syscall_set_nr(current, regs, -1); return; } Thanks! -Kees The following changes since commit da0c9ea146cbe92b832f1b0f694840ea8eb33cce: Linux 5.4-rc2 (2019-10-06 14:27:30 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git tags/seccomp-v5.5-rc1 for you to fetch changes up to 23b2c96fad21886c53f5e1a4ffedd45ddd2e85ba: seccomp: rework define for SECCOMP_USER_NOTIF_FLAG_CONTINUE (2019-10-28 12:29:46 -0700) ---------------------------------------------------------------- seccomp updates for v5.5 - implement SECCOMP_USER_NOTIF_FLAG_CONTINUE (Christian Brauner) - fixes to selftests (Christian Brauner) - remove secure_computing() argument (Christian Brauner) ---------------------------------------------------------------- Christian Brauner (6): seccomp: avoid overflow in implicit constant conversion seccomp: add SECCOMP_USER_NOTIF_FLAG_CONTINUE seccomp: test SECCOMP_USER_NOTIF_FLAG_CONTINUE seccomp: simplify secure_computing() seccomp: fix SECCOMP_USER_NOTIF_FLAG_CONTINUE test seccomp: rework define for SECCOMP_USER_NOTIF_FLAG_CONTINUE arch/arm/kernel/ptrace.c | 2 +- arch/arm64/kernel/ptrace.c | 2 +- arch/parisc/kernel/ptrace.c | 2 +- arch/s390/kernel/ptrace.c | 2 +- arch/um/kernel/skas/syscall.c | 2 +- arch/x86/entry/vsyscall/vsyscall_64.c | 2 +- include/linux/seccomp.h | 6 +- include/uapi/linux/seccomp.h | 29 +++++++ kernel/seccomp.c | 28 +++++-- tools/testing/selftests/seccomp/seccomp_bpf.c | 110 +++++++++++++++++++++++++- 10 files changed, 169 insertions(+), 16 deletions(-) -- Kees Cook

[PATCH v7 00/24] mm/gup: track dma-pinned pages: FOLL_PIN

by John Hubbard

Hi, OK, here is v7, maybe this is the last one. The corresponding git repo and branch is: git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v7 Ira, you reviewed the gup_benchmark patches a bit earlier, but I removed one or two of those review-by tags, due to invasive changes I made after your review (in response to further reviews). So could you please reply to any patches you'd like to have reviewed-by's restoredto, if any? Mainly I'm thinking of "mm/gup_benchmark: support pin_user_pages() and related calls". Also various FOLL_LONGTERM vs pin_longterm*() patches. The following blurb from the v6 cover letter is still applicable, and I'll repeat it here so it doesn't get lost in the patch blizzard: Christoph Hellwig has a preference to do things a little differently, for the devmap cleanup in patch 5 ("mm: devmap: refactor 1-based refcounting for ZONE_DEVICE pages"). That came up in a different review thread, because the patch is out for review in two locations. Here's that review thread: https://lore.kernel.org/r/20191118070826.GB3099@infradead.org ...and I'm hoping that we can defer that request, because otherwise it derails this series, which is starting to otherwise look like it could be ready for 5.5. Changes since v6: * Renamed a couple of routines, to get rid of unnecessary leading underscores: __pin_compound_head() --> grab_compound_head() __record_subpages() --> record_subpages() * Fixed the error fallback (put_compound_head()) so as to match the fix in the previous version: need to put back N * GUP_PIN_COUNTING_BIAS pages, for FOLL_PIN cases. * Factored out yet another common chunk of code, into a new grab_page() routine. * Added a missing compound_head() call to put_compound_head(). * [Re-]added Jens Axboe's reviewed-by tag to the fs/io_uring patch. * Added more reviewed-by's from Jan Kara. Changes since v5: * Fixed the refcounting for huge pages: in most cases, it was only taking one GUP_PIN_COUNTING_BIAS's worth of refs, when it should have been taking one GUP_PIN_COUNTING_BIAS for each subpage. (Much thanks to Jan Kara for spotting that one!) * Renamed user_page_ref_inc() to try_pin_page(), and added a new try_pin_compound_head(). This definitely improves readability. * Factored out some more duplication in the FOLL_PIN and FOLL_GET cases, in gup.c. * Fixed up some straggling "get_" --> "pin_" references in the comments. * Added reviewed-by tags. Changes since v4: * Renamed put_user_page*() --> unpin_user_page(). * Removed all pin_longterm_pages*() calls. We will use FOLL_LONGTERM at the call sites. (FOLL_PIN, however, remains an internal gup flag). This is very nice: many patches just change three characters now: get_user_pages --> pin_user_pages. I think we've found the right balance of wrapper calls and gup flags, for the call sites. * Updated a lot of documentation and commit logs to match the above two large changes. * Changed gup_benchmark tests and run_vmtests, to adapt to one less use case: there is no pin_longterm_pages() call anymore. * This includes a new devmap cleanup patch from Dan Williams, along with a rebased follow-up: patches 4 and 5, already mentioned above. * Fixed patch 10 ("mm/gup: introduce pin_user_pages*() and FOLL_PIN"), so as to make pin_user_pages*() calls act as placeholders for the corresponding get_user_pages*() calls, until a later patch fully implements the DMA-pinning functionality. Thanks to Jan Kara for noticing that. * Fixed the implementation of pin_user_pages_remote(). * Further tweaked patch 2 ("mm/gup: factor out duplicate code from four routines"), in response to Jan Kara's feedback. * Dropped a few reviewed-by tags due to changes that invalidated them. Changes since v3: * VFIO fix (patch 8): applied further cleanup: removed a pre-existing, unnecessary release and reacquire of mmap_sem. Moved the DAX vma checks from the vfio call site, to gup internals, and added comments (and commit log) to clarify. * Due to the above, made a corresponding fix to the pin_longterm_pages_remote(), which was actually calling the wrong gup internal function. * Changed put_user_page() comments, to refer to pin*() APIs, rather than get_user_pages*() APIs. * Reverted an accidental whitespace-only change in the IB ODP code. * Added a few more reviewed-by tags. Changes since v2: * Added a patch to convert IB/umem from normal gup, to gup_fast(). This is also posted separately, in order to hopefully get some runtime testing. * Changed the page devmap code to be a little clearer, thanks to Jerome for that. * Split out the page devmap changes into a separate patch (and moved Ira's Signed-off-by to that patch). * Fixed my bug in IB: ODP code does not require pin_user_pages() semantics. Therefore, revert the put_user_page() calls to put_page(), and leave the get_user_pages() call as-is. * As part of the revert, I am proposing here a change directly from put_user_pages(), to release_pages(). I'd feel better if someone agrees that this is the best way. It uses the more efficient release_pages(), instead of put_page() in a loop, and keep the change to just a few character on one line, but OTOH it is not a pure revert. * Loosened the FOLL_LONGTERM restrictions in the __get_user_pages_locked() implementation, and used that in order to fix up a VFIO bug. Thanks to Jason for that idea. * Note the use of release_pages() in IB: is that OK? * Added a few more WARN's and clarifying comments nearby. * Many documentation improvements in various comments. * Moved the new pin_user_pages.rst from Documentation/vm/ to Documentation/core-api/ . * Commit descriptions: added clarifying notes to the three patches (drm/via, fs/io_uring, net/xdp) that already had put_user_page() calls in place. * Collected all pending Reviewed-by and Acked-by tags, from v1 and v2 email threads. * Lot of churn from v2 --> v3, so it's possible that new bugs sneaked in. NOT DONE: separate patchset is required: * __get_user_pages_locked(): stop compensating for buggy callers who failed to set FOLL_GET. Instead, assert that FOLL_GET is set (and fail if it's not). ====================================================================== Original cover letter (edited to fix up the patch description numbers) This applies cleanly to linux-next and mmotm, and also to linux.git if linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB case") is first applied there. This provides tracking of dma-pinned pages. This is a prerequisite to solving the larger problem of proper interactions between file-backed pages, and [R]DMA activities, as discussed in [1], [2], [3], and in a remarkable number of email threads since about 2017. :) A new internal gup flag, FOLL_PIN is introduced, and thoroughly documented in the last patch's Documentation/vm/pin_user_pages.rst. I believe that this will provide a good starting point for doing the layout lease work that Ira Weiny has been working on. That's because these new wrapper functions provide a clean, constrained, systematically named set of functionality that, again, is required in order to even know if a page is "dma-pinned". In contrast to earlier approaches, the page tracking can be incrementally applied to the kernel call sites that, until now, have been simply calling get_user_pages() ("gup"). In other words, opt-in by changing from this: get_user_pages() (sets FOLL_GET) put_page() to this: pin_user_pages() (sets FOLL_PIN) put_user_page() Because there are interdependencies with FOLL_LONGTERM, a similar conversion as for FOLL_PIN, was applied. The change was from this: get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET) put_page() to this: pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM) put_user_page() ============================================================ Patch summary: * Patches 1-9: refactoring and preparatory cleanup, independent fixes * Patch 10: introduce pin_user_pages(), FOLL_PIN, but no functional changes yet * Patches 11-16: Convert existing put_user_page() callers, to use the new pin*() * Patch 17: Activate tracking of FOLL_PIN pages. * Patches 18-20: convert various callers * Patches: 21-23: gup_benchmark and run_vmtests support * Patch 24: rename put_user_page*() --> unpin_user_page*() ============================================================ Testing: * I've done some overall kernel testing (LTP, and a few other goodies), and some directed testing to exercise some of the changes. And as you can see, gup_benchmark is enhanced to exercise this. Basically, I've been able to runtime test the core get_user_pages() and pin_user_pages() and related routines, but not so much on several of the call sites--but those are generally just a couple of lines changed, each. Not much of the kernel is actually using this, which on one hand reduces risk quite a lot. But on the other hand, testing coverage is low. So I'd love it if, in particular, the Infiniband and PowerPC folks could do a smoke test of this series for me. Also, my runtime testing for the call sites so far is very weak: * io_uring: Some directed tests from liburing exercise this, and they pass. * process_vm_access.c: A small directed test passes. * gup_benchmark: the enhanced version hits the new gup.c code, and passes. * infiniband (still only have crude "IB pingpong" working, on a good day: it's not exercising my conversions at runtime...) * VFIO: compiles (I'm vowing to set up a run time test soon, but it's not ready just yet) * powerpc: it compiles... * drm/via: compiles... * goldfish: compiles... * net/xdp: compiles... * media/v4l2: compiles... ============================================================ Next: * Get the block/bio_vec sites converted to use pin_user_pages(). * Work with Ira and Dave Chinner to weave this together with the layout lease stuff. ============================================================ [1] Some slow progress on get_user_pages() (Apr 2, 2019): https://lwn.net/Articles/784574/ [2] DMA and get_user_pages() (LPC: Dec 12, 2018): https://lwn.net/Articles/774411/ [3] The trouble with get_user_pages() (Apr 30, 2018): https://lwn.net/Articles/753027/ Dan Williams (1): mm: Cleanup __put_devmap_managed_page() vs ->page_free() John Hubbard (23): mm/gup: pass flags arg to __gup_device_* functions mm/gup: factor out duplicate code from four routines mm/gup: move try_get_compound_head() to top, fix minor issues mm: devmap: refactor 1-based refcounting for ZONE_DEVICE pages goldish_pipe: rename local pin_user_pages() routine IB/umem: use get_user_pages_fast() to pin DMA pages media/v4l2-core: set pages dirty upon releasing DMA buffers vfio, mm: fix get_user_pages_remote() and FOLL_LONGTERM mm/gup: introduce pin_user_pages*() and FOLL_PIN goldish_pipe: convert to pin_user_pages() and put_user_page() IB/{core,hw,umem}: set FOLL_PIN via pin_user_pages*(), fix up ODP mm/process_vm_access: set FOLL_PIN via pin_user_pages_remote() drm/via: set FOLL_PIN via pin_user_pages_fast() fs/io_uring: set FOLL_PIN via pin_user_pages() net/xdp: set FOLL_PIN via pin_user_pages() mm/gup: track FOLL_PIN pages media/v4l2-core: pin_user_pages (FOLL_PIN) and put_user_page() conversion vfio, mm: pin_user_pages (FOLL_PIN) and put_user_page() conversion powerpc: book3s64: convert to pin_user_pages() and put_user_page() mm/gup_benchmark: use proper FOLL_WRITE flags instead of hard-coding "1" mm/gup_benchmark: support pin_user_pages() and related calls selftests/vm: run_vmtests: invoke gup_benchmark with basic FOLL_PIN coverage mm, tree-wide: rename put_user_page*() to unpin_user_page*() Documentation/core-api/index.rst | 1 + Documentation/core-api/pin_user_pages.rst | 233 +++++++++ arch/powerpc/mm/book3s64/iommu_api.c | 12 +- drivers/gpu/drm/via/via_dmablit.c | 6 +- drivers/infiniband/core/umem.c | 19 +- drivers/infiniband/core/umem_odp.c | 13 +- drivers/infiniband/hw/hfi1/user_pages.c | 4 +- drivers/infiniband/hw/mthca/mthca_memfree.c | 8 +- drivers/infiniband/hw/qib/qib_user_pages.c | 4 +- drivers/infiniband/hw/qib/qib_user_sdma.c | 8 +- drivers/infiniband/hw/usnic/usnic_uiom.c | 4 +- drivers/infiniband/sw/siw/siw_mem.c | 4 +- drivers/media/v4l2-core/videobuf-dma-sg.c | 8 +- drivers/nvdimm/pmem.c | 6 - drivers/platform/goldfish/goldfish_pipe.c | 35 +- drivers/vfio/vfio_iommu_type1.c | 35 +- fs/io_uring.c | 6 +- include/linux/mm.h | 195 ++++++- include/linux/mmzone.h | 2 + include/linux/page_ref.h | 10 + mm/gup.c | 553 +++++++++++++++----- mm/gup_benchmark.c | 74 ++- mm/huge_memory.c | 44 +- mm/hugetlb.c | 36 +- mm/memremap.c | 76 ++- mm/process_vm_access.c | 28 +- mm/vmstat.c | 2 + net/xdp/xdp_umem.c | 4 +- tools/testing/selftests/vm/gup_benchmark.c | 21 +- tools/testing/selftests/vm/run_vmtests | 22 + 30 files changed, 1121 insertions(+), 352 deletions(-) create mode 100644 Documentation/core-api/pin_user_pages.rst -- 2.24.0

[PATCH] tools/testing/selftests/seccomp: change USER_NOTIF_MAGIC definition

by Max Filippov

USER_NOTIF_MAGIC is used to both initialize seccomp_notif_resp::val and verify syscall resturn value. On 32-bit architectures syscall return value has type long, but the value of USER_NOTIF_MAGIC has type long long because it doesn't fit into long. As a result all syscall return value comparisons with USER_NOTIF_MAGIC are false. This is also reported by the compiler when '-W' is added to CFLAGS. Add explicit type cast to USER_NOTIF_MAGIC definition. This fixes the following seccomp_bpf tests on 32-bit architectures: global.user_notification_basic global.user_notification_child_pid_ns global.user_notification_sibling_pid_ns global.user_notification_fault_recv Signed-off-by: Max Filippov <jcmvbkbc(a)gmail.com> --- tools/testing/selftests/seccomp/seccomp_bpf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/seccomp/seccomp_bpf.c b/tools/testing/selftests/seccomp/seccomp_bpf.c index 7f8b5c8982e3..16cc30e2ade4 100644 --- a/tools/testing/selftests/seccomp/seccomp_bpf.c +++ b/tools/testing/selftests/seccomp/seccomp_bpf.c @@ -3077,7 +3077,7 @@ static int user_trap_syscall(int nr, unsigned int flags) return seccomp(SECCOMP_SET_MODE_FILTER, flags, &prog); } -#define USER_NOTIF_MAGIC 116983961184613L +#define USER_NOTIF_MAGIC ((unsigned long)116983961184613L) TEST(user_notification_basic) { pid_t pid; -- 2.20.1

[PATCH v24 14/24] selftests/x86: Add a selftest for SGX

by Jarkko Sakkinen

Add a selftest for SGX. It is a trivial test where a simple enclave copies one 64-bit word of memory between two memory locations given to the enclave as arguments.

[PATCH v2 00/19] pin_user_pages(): reduced-risk series for Linux 5.5

by John Hubbard

Hi, Changes since v1: * Fixed up ppc in response to Jan Kara's review comments (thanks for those!). * Fixed a kbuilt robot-detected build failure: added a stub function for the !CONFIG_MMU case. * Cover letter: now refers to "unpin_user_page()", reflecting the name change in the last patch (instead of put_user_page() ). * Rebased onto today's linux-next: c165016bac27 ("Add linux-next specific files for 20191125") ======================================================================== Here is a set of well-reviewed (expect for one patch), lower-risk items that can go into Linux 5.5. (Update: the powerpc conversion patch has had some initial review now, since v1 was posted.) This is essentially a cut-down v8 of "mm/gup: track dma-pinned pages: FOLL_PIN" [1], and with one of the VFIO patches split into two patches. The idea here is to get this long list of "noise" checked into 5.5, so that the actual, higher-risk "track FOLL_PIN pages" (which is deferred: not part of this series) will be a much shorter patchset to review. For the v4l2-core changes, I've left those here (instead of sending them separately to the -media tree), in order to get the name change done now (put_user_page --> unpin_user_page). However, I've added a Cc stable, as recommended during the last round of reviews. Here are the relevant notes from the original cover letter, edited to match the current situation: This is a prerequisite to tracking dma-pinned pages. That in turn is a prerequisite to solving the larger problem of proper interactions between file-backed pages, and [R]DMA activities, as discussed in [1], [2], [3], and in a remarkable number of email threads since about 2017. :) A new internal gup flag, FOLL_PIN is introduced, and thoroughly documented in the last patch's Documentation/vm/pin_user_pages.rst. I believe that this will provide a good starting point for doing the layout lease work that Ira Weiny has been working on. That's because these new wrapper functions provide a clean, constrained, systematically named set of functionality that, again, is required in order to even know if a page is "dma-pinned". In contrast to earlier approaches, the page tracking can be incrementally applied to the kernel call sites that, until now, have been simply calling get_user_pages() ("gup"). In other words, opt-in by changing from this: get_user_pages() (sets FOLL_GET) put_page() to this: pin_user_pages() (sets FOLL_PIN) unpin_user_page() Because there are interdependencies with FOLL_LONGTERM, a similar conversion as for FOLL_PIN, was applied. The change was from this: get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET) put_page() to this: pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM) unpin_user_page() [1] https://lore.kernel.org/r/20191121071354.456618-1-jhubbard@nvidia.com thanks, John Hubbard NVIDIA Dan Williams (1): mm: Cleanup __put_devmap_managed_page() vs ->page_free() John Hubbard (18): mm/gup: factor out duplicate code from four routines mm/gup: move try_get_compound_head() to top, fix minor issues goldish_pipe: rename local pin_user_pages() routine mm: fix get_user_pages_remote()'s handling of FOLL_LONGTERM vfio: fix FOLL_LONGTERM use, simplify get_user_pages_remote() call mm/gup: introduce pin_user_pages*() and FOLL_PIN goldish_pipe: convert to pin_user_pages() and put_user_page() IB/{core,hw,umem}: set FOLL_PIN via pin_user_pages*(), fix up ODP mm/process_vm_access: set FOLL_PIN via pin_user_pages_remote() drm/via: set FOLL_PIN via pin_user_pages_fast() fs/io_uring: set FOLL_PIN via pin_user_pages() net/xdp: set FOLL_PIN via pin_user_pages() media/v4l2-core: set pages dirty upon releasing DMA buffers media/v4l2-core: pin_user_pages (FOLL_PIN) and put_user_page() conversion vfio, mm: pin_user_pages (FOLL_PIN) and put_user_page() conversion powerpc: book3s64: convert to pin_user_pages() and put_user_page() mm/gup_benchmark: use proper FOLL_WRITE flags instead of hard-coding "1" mm, tree-wide: rename put_user_page*() to unpin_user_page*() Documentation/core-api/index.rst | 1 + Documentation/core-api/pin_user_pages.rst | 233 ++++++++++++++ arch/powerpc/mm/book3s64/iommu_api.c | 12 +- drivers/gpu/drm/via/via_dmablit.c | 6 +- drivers/infiniband/core/umem.c | 4 +- drivers/infiniband/core/umem_odp.c | 13 +- drivers/infiniband/hw/hfi1/user_pages.c | 4 +- drivers/infiniband/hw/mthca/mthca_memfree.c | 8 +- drivers/infiniband/hw/qib/qib_user_pages.c | 4 +- drivers/infiniband/hw/qib/qib_user_sdma.c | 8 +- drivers/infiniband/hw/usnic/usnic_uiom.c | 4 +- drivers/infiniband/sw/siw/siw_mem.c | 4 +- drivers/media/v4l2-core/videobuf-dma-sg.c | 8 +- drivers/nvdimm/pmem.c | 6 - drivers/platform/goldfish/goldfish_pipe.c | 35 +- drivers/vfio/vfio_iommu_type1.c | 35 +- fs/io_uring.c | 6 +- include/linux/mm.h | 77 +++-- mm/gup.c | 340 +++++++++++++------- mm/gup_benchmark.c | 9 +- mm/memremap.c | 80 ++--- mm/process_vm_access.c | 28 +- net/xdp/xdp_umem.c | 4 +- tools/testing/selftests/vm/gup_benchmark.c | 6 +- 24 files changed, 650 insertions(+), 285 deletions(-) create mode 100644 Documentation/core-api/pin_user_pages.rst -- 2.24.0

[PATCH v3 00/19] x86/cpu: Clean up handling of VMX features

by Sean Christopherson

Clean up a handful of interrelated warts in the kernel's handling of VMX: - Enable VMX in IA32_FEATURE_CONTROL during boot instead of on-demand during KVM load to avoid future contention over IA32_FEATURE_CONTROL. - Rework VMX feature reporting so that it is accurate and up-to-date, now and in the future. - Consolidate code across CPUs that support VMX. This series stems from two separate but related issues. The first issue, pointed out by Boris in the SGX enabling series[1], is that the kernel currently doesn't ensure the IA32_FEATURE_CONTROL MSR is configured during boot. The second issue is that the kernel's reporting of VMX features is stale, potentially inaccurate, and difficult to maintain. Please holler if you don't want to be cc'd on future versions of this series, or only want to be cc'd on select patches. v3: - Rebase to tip/master, ceceaf1f12ba ("Merge branch 'WIP.x86/cleanups'"). - Rename the feature control MSR bit defines [Boris]. - Rewrite the error message displayed when reading feature control MSR faults on a VMX capable CPU to explicitly state that it's likely a hardware or hypervisor issue [Boris]. - Collect a Reviewed-by for the LMCE change [Boris]. - Enable VMX in feature control (if it's unlocked) if and only if KVM is enabled [Paolo]. - Remove a big pile of redudant MSR defines from the KVM selftests that was discovered when renaming the feature control defines. - Fix a changelog typoe [Boris]. v2: - Rebase to latest tip/x86/cpu (1edae1ae6258, "x86/Kconfig: Enforce...) - Collect Jim's reviews. - Fix a typo in setting of EPT capabilities [TonyWWang-oc]. - Remove defines for reserved VMX feature flags [Paolo]. - Print the VMX features under "flags" and maintain all existing names to be backward compatible with the ABI [Paolo]. - Create aggregate APIC features to report FLEXPRIORITY and APICV, so that the full feature *and* their associated individual features are printed, e.g. to aid in recognizing why an APIC feature isn't being used. - Fix a few copy paste errors in changelogs. v1 cover letter: == IA32_FEATURE_CONTROL == Lack of IA32_FEATURE_CONTROL configuration during boot isn't a functional issue in the current kernel as the majority of platforms set and lock IA32_FEATURE_CONTROL in firmware. And when the MSR is left unlocked, KVM is the only subsystem that writes IA32_FEATURE_CONTROL. That will change if/when SGX support is enabled, as SGX will also want to fully enable itself when IA32_FEATURE_CONTROL is unlocked. == VMX Feature Reporting == VMX features are not enumerated via CPUID, but instead are enumerated through VMX MSRs. As a result, new VMX features are not automatically reported via /proc/cpuinfo. An attempt was made long ago to report interesting and/or meaningful VMX features by synthesizing select features into a Linux-defined cpufeatures word. Synthetic feature flags worked for the initial purpose, but the existence of the synthetic flags was forgotten almost immediately, e.g. only one new flag (EPT A/D) has been added in the the decade since the synthetic VMX features were introduced, while VMX and KVM have gained support for many new features. Placing the synthetic flags in x86_capability also allows them to be queried via cpu_has() and company, which is misleading as the flags exist purely for reporting via /proc/cpuinfo. KVM, the only in-kernel user of VMX, ignores the flags. Last but not least, VMX features are reported in /proc/cpuinfo even when VMX is unusable due to lack of enabling in IA32_FEATURE_CONTROL. == Caveats == All of the testing of non-standard flows was done in a VM, as I don't have a system that leaves IA32_FEATURE_CONTROL unlocked, or locks it with VMX disabled. The Centaur and Zhaoxin changes are somewhat speculative, as I haven't confirmed they actually support IA32_FEATURE_CONTROL, or that they want to gain "official" KVM support. I assume they unofficially support KVM given that both CPUs went through the effort of enumerating VMX features. That in turn would require them to support IA32_FEATURE_CONTROL since KVM will fault and refuse to load if the MSR doesn't exist.

[PATCH] selftests: pmtu: use -oneline for ip route list cache

by Thadeu Lima de Souza Cascardo

Some versions of iproute2 will output more than one line per entry, which will cause the test to fail, like: TEST: ipv6: list and flush cached exceptions [FAIL] can't list cached exceptions That happens, for example, with iproute2 4.15.0. When using the -oneline option, this will work just fine: TEST: ipv6: list and flush cached exceptions [ OK ] This also works just fine with a more recent version of iproute2, like 5.4.0. For some reason, two lines are printed for the IPv4 test no matter what version of iproute2 is used. Use the same -oneline parameter there instead of counting the lines twice.

kselftest: failed to build with -C tool/testing/selftests when KBUILD_OUTPUT is set

by Cristian Marussi

Hi while testing on linux-next I see that, when KBUILD_OUTPUT is set in the env, running something like (using TARGETS=exec as a random subsystem here...) $ make TARGETS=exec INSTALL_PATH=/nfs/LTP-official-debian-aarch64-rootfs/opt/KSFT_next kselftest-install works fine as usual, WHILE the alternative invocation (still documented in Documentation/dev-tools/kselftest.rst) make -C tools/testing/selftests/ TARGETS=exec INSTALL_PATH=/nfs/LTP-official-debian-aarch64-rootfs/opt/KSFT_next install fails miserably with: ... ...

[PATCH] fs/ext4/inode-test: Fix inode test on 32 bit platforms.

by Iurii Zaikin

[PATCH] kunit: test: Improve error messages for kunit_tool when kunitconfig is invalid

by Heidi Fahim

Previous error message for invalid kunitconfig was vague. Added to it so that it lists invalid fields and prompts for them to be removed.

[PATCH v3 0/4] PM: QoS: Restore DEV_PM_QOS_MIN/MAX_FREQUENCY

by Leonard Crestez

Support for frequency limits in dev_pm_qos was removed when cpufreq was switched to freq_qos, this series attempts to restore it by reimplementing on top of freq_qos. Discussion about removal is here: https://lore.kernel.org/linux-pm/VI1PR04MB7023DF47D046AEADB4E051EBEE680@VI1… The cpufreq core switched away because it needs contraints at the level of a "cpufreq_policy" which cover multiple cpus so dev_pm_qos coupling to struct device was not useful. Cpufreq could only use dev_pm_qos by implementing an additional layer of aggregation anyway. However in the devfreq subsystem scaling is always performed on a per-device basis so dev_pm_qos is a very good match. Support for dev_pm_qos in devfreq core is here: https://patchwork.kernel.org/cover/11252409/ That series is RFC mostly because it needs these PM core patches. Earlier versions got entangled in some locking cleanups but those are not strictly necessary to get dev_pm_qos functionality. In theory if freq_qos is extended to handle conflicting min/max values then this sharing would be valuable. Right now freq_qos just ties two unrelated pm_qos aggregations for min and max freq. --- This is implemented by embeding a freq_qos_request inside dev_pm_qos_request: the data field was already an union in order to deal with flag requests. The internal freq_qos_apply is exported so that it can be called from dev_pm_qos apply_constraints. The dev_pm_qos_constraints_destroy function has no obvious equivalent in freq_qos and the whole approach of "removing requests" is somewhat dubios: request objects should be owned by consumers and the list of qos requests should be empty when the target device is deleted. Changes since v2: * #define PM_QOS_MAX_FREQUENCY_DEFAULT_VALUE FREQ_QOS_MAX_DEFAULT_VALUE * #define FREQ_QOS_MAX_DEFAULT_VALUE S32_MAX (in new patch) * Add initial kunit test for freq_qos, validating the MAX_DEFAULT_VALUE found by Matthias. Link to v2: https://patchwork.kernel.org/cover/11250413/ First two patches can be applied separated Changes since v1: * Don't rename or EXPORT_SYMBOL_GPL the freq_qos_apply function; just drop the static marker.

[PATCH v8 1/9] hugetlb_cgroup: Add hugetlb_cgroup reservation counter

by Mina Almasry

These counters will track hugetlb reservations rather than hugetlb memory faulted in. This patch only adds the counter, following patches add the charging and uncharging of the counter. Problem: Currently tasks attempting to allocate more hugetlb memory than is available get a failure at mmap/shmget time. This is thanks to Hugetlbfs Reservations [1]. However, if a task attempts to allocate hugetlb memory only more than its hugetlb_cgroup limit allows, the kernel will allow the mmap/shmget call, but will SIGBUS the task when it attempts to fault the memory in. We have developers interested in using hugetlb_cgroups, and they have expressed dissatisfaction regarding this behavior. We'd like to improve this behavior such that tasks violating the hugetlb_cgroup limits get an error on mmap/shmget time, rather than getting SIGBUS'd when they try to fault the excess memory in. The underlying problem is that today's hugetlb_cgroup accounting happens at hugetlb memory *fault* time, rather than at *reservation* time. Thus, enforcing the hugetlb_cgroup limit only happens at fault time, and the offending task gets SIGBUS'd. Proposed Solution: A new page counter named hugetlb.xMB.reservation_[limit|usage]_in_bytes. This counter has slightly different semantics than hugetlb.xMB.[limit|usage]_in_bytes: - While usage_in_bytes tracks all *faulted* hugetlb memory, reservation_usage_in_bytes tracks all *reserved* hugetlb memory and hugetlb memory faulted in without a prior reservation. - If a task attempts to reserve more memory than limit_in_bytes allows, the kernel will allow it to do so. But if a task attempts to reserve more memory than reservation_limit_in_bytes, the kernel will fail this reservation. This proposal is implemented in this patch series, with tests to verify functionality and show the usage. We also added cgroup-v2 support to hugetlb_cgroup so that the new use cases can be extended to v2. Alternatives considered: 1. A new cgroup, instead of only a new page_counter attached to the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code duplication with hugetlb_cgroup. Keeping hugetlb related page counters under hugetlb_cgroup seemed cleaner as well. 2. Instead of adding a new counter, we considered adding a sysctl that modifies the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at reservation time rather than fault time. Adding a new page_counter seems better as userspace could, if it wants, choose to enforce different cgroups differently: one via limit_in_bytes, and another via reservation_limit_in_bytes. This could be very useful if you're transitioning how hugetlb memory is partitioned on your system one cgroup at a time, for example.

[PATCH 00/19] pin_user_pages(): reduced-risk series for Linux 5.5

by John Hubbard

Hi, Here is a set of well-reviewed (expect for one patch), lower-risk items that can go into Linux 5.5. The one patch that wasn't reviewed is the powerpc conversion, and it's still at this point a no-op, because tracking isn't yet activated. This is based on linux-next: b9d3d01405061bb42358fe53f824e894a1922ced ("Add linux-next specific files for 20191122"). This is essentially a cut-down v8 of "mm/gup: track dma-pinned pages: FOLL_PIN" [1], and with one of the VFIO patches split into two patches. The idea here is to get this long list of "noise" checked into 5.5, so that the actual, higher-risk "track FOLL_PIN pages" (which is deferred: not part of this series) will be a much shorter patchset to review. For the v4l2-core changes, I've left those here (instead of sending them separately to the -media tree), in order to get the name change done now (put_user_page --> unpin_user_page). However, I've added a Cc stable, as recommended during the last round of reviews. Here are the relevant notes from the original cover letter, edited to match the current situation: This is a prerequisite to tracking dma-pinned pages. That in turn is a prerequisite to solving the larger problem of proper interactions between file-backed pages, and [R]DMA activities, as discussed in [1], [2], [3], and in a remarkable number of email threads since about 2017. :) A new internal gup flag, FOLL_PIN is introduced, and thoroughly documented in the last patch's Documentation/vm/pin_user_pages.rst. I believe that this will provide a good starting point for doing the layout lease work that Ira Weiny has been working on. That's because these new wrapper functions provide a clean, constrained, systematically named set of functionality that, again, is required in order to even know if a page is "dma-pinned". In contrast to earlier approaches, the page tracking can be incrementally applied to the kernel call sites that, until now, have been simply calling get_user_pages() ("gup"). In other words, opt-in by changing from this: get_user_pages() (sets FOLL_GET) put_page() to this: pin_user_pages() (sets FOLL_PIN) put_user_page() Because there are interdependencies with FOLL_LONGTERM, a similar conversion as for FOLL_PIN, was applied. The change was from this: get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET) put_page() to this: pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM) put_user_page() [1] https://lore.kernel.org/r/20191121071354.456618-1-jhubbard@nvidia.com thanks, John Hubbard NVIDIA Dan Williams (1): mm: Cleanup __put_devmap_managed_page() vs ->page_free() John Hubbard (18): mm/gup: factor out duplicate code from four routines mm/gup: move try_get_compound_head() to top, fix minor issues goldish_pipe: rename local pin_user_pages() routine mm: fix get_user_pages_remote()'s handling of FOLL_LONGTERM vfio: fix FOLL_LONGTERM use, simplify get_user_pages_remote() call mm/gup: introduce pin_user_pages*() and FOLL_PIN goldish_pipe: convert to pin_user_pages() and put_user_page() IB/{core,hw,umem}: set FOLL_PIN via pin_user_pages*(), fix up ODP mm/process_vm_access: set FOLL_PIN via pin_user_pages_remote() drm/via: set FOLL_PIN via pin_user_pages_fast() fs/io_uring: set FOLL_PIN via pin_user_pages() net/xdp: set FOLL_PIN via pin_user_pages() media/v4l2-core: set pages dirty upon releasing DMA buffers media/v4l2-core: pin_user_pages (FOLL_PIN) and put_user_page() conversion vfio, mm: pin_user_pages (FOLL_PIN) and put_user_page() conversion powerpc: book3s64: convert to pin_user_pages() and put_user_page() mm/gup_benchmark: use proper FOLL_WRITE flags instead of hard-coding "1" mm, tree-wide: rename put_user_page*() to unpin_user_page*() Documentation/core-api/index.rst | 1 + Documentation/core-api/pin_user_pages.rst | 233 ++++++++++++++ arch/powerpc/mm/book3s64/iommu_api.c | 12 +- drivers/gpu/drm/via/via_dmablit.c | 6 +- drivers/infiniband/core/umem.c | 4 +- drivers/infiniband/core/umem_odp.c | 13 +- drivers/infiniband/hw/hfi1/user_pages.c | 4 +- drivers/infiniband/hw/mthca/mthca_memfree.c | 8 +- drivers/infiniband/hw/qib/qib_user_pages.c | 4 +- drivers/infiniband/hw/qib/qib_user_sdma.c | 8 +- drivers/infiniband/hw/usnic/usnic_uiom.c | 4 +- drivers/infiniband/sw/siw/siw_mem.c | 4 +- drivers/media/v4l2-core/videobuf-dma-sg.c | 8 +- drivers/nvdimm/pmem.c | 6 - drivers/platform/goldfish/goldfish_pipe.c | 35 +-- drivers/vfio/vfio_iommu_type1.c | 35 +-- fs/io_uring.c | 6 +- include/linux/mm.h | 77 +++-- mm/gup.c | 332 +++++++++++++------- mm/gup_benchmark.c | 9 +- mm/memremap.c | 80 ++--- mm/process_vm_access.c | 28 +- net/xdp/xdp_umem.c | 4 +- tools/testing/selftests/vm/gup_benchmark.c | 6 +- 24 files changed, 642 insertions(+), 285 deletions(-) create mode 100644 Documentation/core-api/pin_user_pages.rst -- 2.24.0
