[PATCH v3 00/19 5.15.y] Backport minmax.h updates from v6.17-rc7

by Eliav Farber

This series backports 19 patches to update minmax.h in the 5.15.y branch, aligning it with v6.17-rc7. The ultimate goal is to synchronize all longterm branches so that they include the full set of minmax.h changes. 6.12.y was already backported and changes are part of v6.12.49. 6.6.y was already backported and changes are part of v6.6.109. 6.1.y was already backported and changes are currently in the 6.1-stable tree. The key motivation is to bring in commit d03eba99f5bf ("minmax: allow min()/max()/clamp() if the arguments have the same signedness"), which is missing in kernel 5.10.y. In mainline, this change enables min()/max()/clamp() to accept mixed argument types, provided both have the same signedness. Without it, backported patches that use these forms may trigger compiler warnings, which escalate to build failures when -Werror is enabled. Changes in v3: - Fix fs/erofs/zdata.h in patch 06/19 to use MIN_T instead of min_t to fix build on the following patch (07/19): In file included from ./include/linux/kernel.h:16, from ./include/linux/list.h:9, from ./include/linux/wait.h:7, from ./include/linux/wait_bit.h:8, from ./include/linux/fs.h:6, from fs/erofs/internal.h:10, from fs/erofs/zdata.h:9, from fs/erofs/zdata.c:6: fs/erofs/zdata.c: In function ‘z_erofs_decompress_pcluster’: fs/erofs/zdata.h:185:61: error: ISO C90 forbids variable length array ‘pages_onstack’ [-Werror=vla] 185 | min_t(unsigned int, THREAD_SIZE / 8 / sizeof(struct page *), 96U) | ^~~~ ./include/linux/minmax.h:49:23: note: in definition of macro ‘__cmp_once_unique’ 49 | ({ type ux = (x); type uy = (y); __cmp(op, ux, uy); }) | ^ ./include/linux/minmax.h:164:27: note: in expansion of macro ‘__cmp_once’ 164 | #define min_t(type, x, y) __cmp_once(min, type, x, y) | ^~~~~~~~~~ fs/erofs/zdata.h:185:9: note: in expansion of macro ‘min_t’ 185 | min_t(unsigned int, THREAD_SIZE / 8 / sizeof(struct page *), 96U) | ^~~~~ fs/erofs/zdata.c:847:36: note: in expansion of macro ‘Z_EROFS_VMAP_ONSTACK_PAGES’ 847 | struct page *pages_onstack[Z_EROFS_VMAP_ONSTACK_PAGES]; | ^~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors - Increase test coverage using `make allyesconfig` and `make allmodconfig` for arm64, arm, x86_64 and i386 architectures.

Run selftest via web server with UI on localhost

by Alexey Melezhik

Hi! I am kind of a newbie here, no experience in kernel development but with decent experience in QA automation and automation in general . What about giving a user an ability to run selftest tests in localhost server via web server with UI. I know many things are customizable via terminal with current setup however the UI approach might have some benefits : - processing raw KTAP output in nicer and more human readable way - having build step and test step as separate reports - having running/installing kernel ( which is tested ) as separate test/report - automatically dump server environment in case of any errors ( good input data before submitting bugs ) - automatically installing dependencies required for specific environment ( all this foo-dev packages ) - allow user split tests into different groups ( based on existing self test runner capabilities) and thus generate separate browseable reports - run long running tests in background with possible job termination via UI So it’s all about convenience and more easier way for QA people to do testing I see it as a good option, using current terminal run flow as a default PS if people like the idea I can come up with some prototype in a separate patch , I already have some tools in minds ( some of them I am author of ) Thanks Alexey

[PATCH net repost] selftests: drv-net: make linters happy with our imports

by Jakub Kicinski

Linters are still not very happy with our __init__ files, which was pointed out in recent review (see Link). We have previously started importing things one by one to make linters happy with the test files (which import from __init__). But __init__ file itself still makes linters unhappy. To clean it up I believe we must completely remove the wildcard imports, and assign the imported modules to __all__. hds.py needs to be fixed because it seems to be importing the Python standard random from lib.net. We can't use ksft_pr() / ktap_result() in case importing from net.lib fails. Linters complain that those helpers themselves may not have been imported.

I'm not super confident 'cause my Python isn't properly learned. Sending for net, even tho its not a real fix. I think that getting it applied during the merge window may be okay? No strong prefence. I'm slightly worried that merging it in net-next after the MW will leave us with a release cycle full of merge conflicts. --- tools/testing/selftests/drivers/net/hds.py | 3 +- .../selftests/drivers/net/lib/py/__init__.py | 43 ++++++++++++++----- 2 files changed, 34 insertions(+), 12 deletions(-) diff --git a/tools/testing/selftests/drivers/net/hds.py b/tools/testing/selftests/drivers/net/hds.py index a2011474e625..c4fe049e9baa 100755 --- a/tools/testing/selftests/drivers/net/hds.py +++ b/tools/testing/selftests/drivers/net/hds.py @@ -3,11 +3,12 @@ import errno import os +import random from typing import Union from lib.py import ksft_run, ksft_exit, ksft_eq, ksft_raises, KsftSkipEx from lib.py import CmdExitFailure, EthtoolFamily, NlError from lib.py import NetDrvEnv -from lib.py import defer, ethtool, ip, random +from lib.py import defer, ethtool, ip def _get_hds_mode(cfg, netnl) -> str: diff --git a/tools/testing/selftests/drivers/net/lib/py/__init__.py b/tools/testing/selftests/drivers/net/lib/py/__init__.py index 2a645415c4ca..e6c070f32f51 100644 --- a/tools/testing/selftests/drivers/net/lib/py/__init__.py +++ b/tools/testing/selftests/drivers/net/lib/py/__init__.py @@ -1,5 +1,13 @@ # SPDX-License-Identifier: GPL-2.0 +""" +Driver test environment. +NetDrvEnv and NetDrvEpEnv are the main environment classes. +Former is for local host only tests, latter creates / connects +to a remote endpoint.

[PATCH 0/7] tools/nolibc: reduce __nolibc_enosys() fallbacks

by Thomas Weißschuh

The __nolibc_enosys() fallback is used when the UAPI headers do not provide a certain syscall number or any possible fallback syscall. This is either because the syscall definition is fairly new and nolibc tries to be compatible with old UAPI headers or an architecture does not support a syscall at all. Many of these __nolibc_enosys() fallbacks have become unnecessary. Either because the "new" syscalls or not so new anymore or real fallbacks have been implemented in the meantime. Unnecessary usages of __nolibc_enosys() as it is not obvious anymore if a given function is really implemented on all architectures.

[PATCH net v2] selftests: net: unify the Makefile formats

by Jakub Kicinski

We get a significant number of conflicts between net and net-next because of selftests Makefile changes. People tend to append new test cases at the end of the Makefile when there's no clear sort order. Sort all networking selftests Makefiles, use the following format: VAR_NAME := \ entry1 \ entry2 \ entry3 \ # end of VAR_NAME Some Makefiles are already pretty close to this.

[PATCH net v6] selftest:net:ovpn: Fix uninit return values

by Sidharth Seela

Fix functions that return undefined values. These issues were caught by running clang using LLVM=1 option.

[PATCH net] selftests: net: unify the Makefile formats

by Jakub Kicinski

We get a significant number of conflicts between net and net-next because of selftests Makefile changes. People tend to append new test cases at the end of the Makefile when there's no clear sort order. Sort all networking selftests Makefiles, use the following format: VAR_NAME := \ entry1 \ entry2 \ entry3 \ # end of VAR_NAME Some Makefiles are already pretty close to this. Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> --- I think we need to apply this during the merge window, otherwise the conflicts will be crazy.

Send a non-trivial number of packets and make sure that they are counted correctly in qstats. Per qstats specification XDP is the first layer of the stack so we should see Rx and Tx counters go up for packets which went thru XDP.

[PATCH net 8/9] selftests: drv-net: pp_alloc_fail: lower traffic expectations

by Jakub Kicinski

Lower the expected level of traffic in the pp_alloc_fail test and calculate failure counter thresholds based on the traffic rather than using a fixed constant. We only have "QEMU HW" in NIPA right now, and the test (due to debug dependencies) only works on debug kernels in the first place. We need some place for it to pass otherwise it seems to be bit rotting. So lower the traffic threshold so that it passes on QEMU and with a debug kernel...

From: Rong Tao <rongtao(a)cestc.cn> Since commit 1b8abbb12128 ("bpf...d_path(): constify path argument"), the first parameter of the bpf_d_path() has been changed to a const constant.

[RFC PATCH v3 nf-next] selftests: netfilter: Add bridge_fastpath.sh

by Eric Woudstra

Add a script to test various scenarios where a bridge is involved in the fastpath. It runs tests in the forward path, and also in a bridged path. The setup is similar to a basic home router with multiple lan ports. It uses 3 pairs of veth-devices. Each or all pairs can be replaced by a pair of real interfaces, interconnected by wire. This is necessary to test the behavior when dealing with dsa ports, foreign (dsa) ports and switchdev userports that support SWITCHDEV_OBJ_ID_PORT_VLAN. See the head of the script for a detailed description. Run without arguments to perform all tests on veth-devices. Signed-off-by: Eric Woudstra <ericwouds(a)gmail.com> --- This test script is written first for the proposed bridge-fastpath patch-sets, but it's use is more general and can easily be expanded. Changes in v3: - Removed all warnings reported by shellcheck -x -e SC2317 - Improved del_pppoe(), check if interfaces are removed - Added is_known_issue() to warn instead of error for known issues - Link down and (hardware) interfaces to default netns at end of script - Removed matching ip(v6) address Changes in v2: - Moved test-series to functions - Moved code to set_pair_link() up/down - Added conntrack zone to bridged traffic - Test bridge chain prerouting in test without fastpath and bridge chain forward in tests with fastpath Some example outputs of this last version of patches from

[PATCH bpf] selftests/bpf: fix implicit-function-declaration errors

by Matthieu Baerts (NGI0)

When trying to build the latest BPF selftests, with a debug kernel config, Pahole 1.30 and CLang 20.1.8 (and GCC 15.2), I got these errors: progs/dynptr_success.c:579:9: error: call to undeclared function 'bpf_dynptr_slice'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 579 | data = bpf_dynptr_slice(&ptr, 0, NULL, 1); | ^ progs/dynptr_success.c:579:9: note: did you mean 'bpf_dynptr_size'? .virtme/build-debug-btf//tools/include/vmlinux.h:120280:14: note: 'bpf_dynptr_size' declared here 120280 | extern __u32 bpf_dynptr_size(const struct bpf_dynptr *p) __weak __ksym; | ^ progs/dynptr_success.c:579:7: error: incompatible integer to pointer conversion assigning to '__u64 *' (aka 'unsigned long long *') from 'int' [-Wint-conversion] 579 | data = bpf_dynptr_slice(&ptr, 0, NULL, 1); | ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ progs/dynptr_success.c:596:9: error: call to undeclared function 'bpf_dynptr_slice'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 596 | data = bpf_dynptr_slice(&ptr, 0, NULL, 10); | ^ progs/dynptr_success.c:596:7: error: incompatible integer to pointer conversion assigning to 'char *' from 'int' [-Wint-conversion] 596 | data = bpf_dynptr_slice(&ptr, 0, NULL, 10); | ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I don't have these errors without the debug kernel config from kernel/configs/debug.config. With the debug kernel, bpf_dynptr_slice() is not declared in vmlinux.h. It is declared there without debug.config.

[PATCH v3 0/3] VMM can handle guest SEA via KVM_EXIT_ARM_SEA

by Jiaqi Yan

Problem ======= When host APEI is unable to claim a synchronous external abort (SEA) during guest abort, today KVM directly injects an asynchronous SError into the VCPU then resumes it. The injected SError usually results in unpleasant guest kernel panic. One of the major situation of guest SEA is when VCPU consumes recoverable uncorrected memory error (UER), which is not uncommon at all in modern datacenter servers with large amounts of physical memory. Although SError and guest panic is sufficient to stop the propagation of corrupted memory, there is room to recover from an UER in a more graceful manner. Proposed Solution ================= The idea is, we can replay the SEA to the faulting VCPU. If the memory error consumption or the fault that cause SEA is not from guest kernel, the blast radius can be limited to the poison-consuming guest process, while the VM can keep running. In addition, instead of doing under the hood without involving userspace, there are benefits to redirect the SEA to VMM: - VM customers care about the disruptions caused by memory errors, and VMM usually has the responsibility to start the process of notifying the customers of memory error events in their VMs. For example some cloud provider emits a critical log in their observability UI [1], and provides a playbook for customers on how to mitigate disruptions to their workloads. - VMM can protect future memory error consumption by unmapping the poisoned pages from stage-2 page table with KVM userfault [2], or by splitting the memslot that contains the poisoned pages. - VMM can keep track of SEA events in the VM. When VMM thinks the status on the host or the VM is bad enough, e.g. number of distinct SEAs exceeds a threshold, it can restart the VM on another healthy host. - Behavior parity with x86 architecture. When machine check exception (MCE) is caused by VCPU, kernel or KVM signals userspace SIGBUS to let VMM either recover from the MCE, or terminate itself with VM. The prior RFC proposes to implement SIGBUS on arm64 as well, but Marc preferred KVM exit over signal [3]. However, implementation aside, returning SEA to VMM is on par with returning MCE to VMM. Once SEA is redirected to VMM, among other actions, VMM is encouraged to inject external aborts into the faulting VCPU. New UAPIs ========= This patchset introduces following userspace-visible changes to empower VMM to control what happens for SEA on guest memory: - KVM_CAP_ARM_SEA_TO_USER. While taking SEA, if userspace has enabled this new capability at VM creation, and the SEA is not owned by kernel allocated memory, instead of injecting SError, return KVM_EXIT_ARM_SEA to userspace. - KVM_EXIT_ARM_SEA. This is the VM exit reason VMM gets. The details about the SEA is provided in arm_sea as much as possible, including sanitized ESR value at EL2, faulting guest virtual and physical addresses if available. * From v2 [4]: - Rebased on "[PATCH] KVM: arm64: nv: Handle SEAs due to VNCR redirection" [5] and kvmarm/next commit 7b8346bd9fce ("KVM: arm64: Don't attempt vLPI mappings when vPE allocation is disabled") - Took the host_owns_sea implementation from Oliver [6, 7]. - Excluded the guest SEA injection patches. - Updated selftest. * From v1 [8]: - Rebased on commit 4d62121ce9b5 ("KVM: arm64: vgic-debug: Avoid dereferencing NULL ITE pointer"). - Sanitize ESR_EL2 before reporting it to userspace. - Do not do KVM_EXIT_ARM_SEA when SEA is caused by memory allocated to stage-2 translation table.

[PATCH] selftests/bpf: Add -Wsign-compare C compilation flag

by Mehdi Ben Hadj Khelifa

-Change all the source files and the corresponding headers to having matching sign comparisons. Signed-off-by: Mehdi Ben Hadj Khelifa <mehdi.benhadjkhelifa(a)gmail.com> --- As suggested by the TODO, -Wsign-compare was added to the C compilation flags for the selftests/bpf/Makefile and all corresponding files in selftests and a single file under tools/lib/bpf/usdt.bpf.h have been carefully changed to account for correct sign comparisons either by explicit casting or changing the variable type.Only local variables and variables which are in limited scope have been changed in cases where it doesn't break the code.Other struct variables or global ones have left untouched to avoid other conflicts and opted to explicit casting in this case.This change will help avoid implicit type conversions and have predictable behavior. I have already compiled all bpf tests with no errors as well as the kernel and have ran all the selftests with no obvious side effects. I would like to know if it's more convinient to have all changes as a single patch like here or if it needs to be divided in some way and sent as a patch series.

[PATCH net v6 0/4] net: netpoll: fix memory leak and add comprehensive selftests

by Breno Leitao

Fix a memory leak in netpoll and introduce netconsole selftests that expose the issue when running with kmemleak detection enabled. This patchset includes a selftest for netpoll with multiple concurrent users (netconsole + bonding), which simulates the scenario from test[1] that originally demonstrated the issue allegedly fixed by commit efa95b01da18 ("netpoll: fix use after free") - a commit that is now being reverted. Sending this to "net" branch because this is a fix, and the selftest might help with the backports validation. Link: https://lore.kernel.org/lkml/96b940137a50e5c387687bb4f57de8b0435a653f.14048… [1] Signed-off-by: Breno Leitao <leitao(a)debian.org> --- Changes in v6: - Expand the tests even more and some small fixups - Moved the test to bonding selftests - Link to v5: https://lore.kernel.org/r/20250918-netconsole_torture-v5-0-77e25e0a4eb6@deb… Changes in v5: - Set CONFIG_BONDING=m in selftests/drivers/net/config. - Link to v4: https://lore.kernel.org/r/20250917-netconsole_torture-v4-0-0a5b3b8f81ce@deb… Changes in v4: - Added an additional selftest to test multiple netpoll users in parallel - Link to v3: https://lore.kernel.org/r/20250905-netconsole_torture-v3-0-875c7febd316@deb… Changes in v3: - This patchset is a merge of the fix and the selftest together as recommended by Jakub. Changes in v2: - Reuse the netconsole creation from lib_netcons.sh. Thus, refactoring the create_dynamic_target() (Jakub) - Move the "wait" to after all the messages has been sent. - Link to v1: https://lore.kernel.org/r/20250902-netconsole_torture-v1-1-03c6066598e9@deb… --- Breno Leitao (4): net: netpoll: fix incorrect refcount handling causing incorrect cleanup selftest: netcons: refactor target creation selftest: netcons: create a torture test selftest: netcons: add test for netconsole over bonded interfaces net/core/netpoll.c | 7 +++++-- tools/testing/selftests/drivers/net/Makefile | 1 + tools/testing/selftests/drivers/net/bonding/Makefile | 2 ++ tools/testing/selftests/drivers/net/bonding/config | 4 ++++ tools/testing/selftests/drivers/net/bonding/netcons_over_bonding.sh | 221 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ tools/testing/selftests/drivers/net/lib/sh/lib_netcons.sh | 189 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++------------------ tools/testing/selftests/drivers/net/netcons_torture.sh | 127 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 7 files changed, 531 insertions(+), 20 deletions(-) --- base-commit: f1455695d2d99894b65db233877acac9a0e120b9 change-id: 20250902-netconsole_torture-8fc23f0aca99 Best regards, -- Breno Leitao <leitao(a)debian.org>

[PATCH 00/19 5.15.y] Backport minmax.h updates from v6.17-rc7

by Eliav Farber

This series backports 19 patches to update minmax.h in the 5.15.y branch, aligning it with v6.17-rc7. The ultimate goal is to synchronize all longterm branches so that they include the full set of minmax.h changes (6.12.y and 6.6.y were already backported by me and are now aligned, 6.1.y is in progress). The key motivation is to bring in commit d03eba99f5bf ("minmax: allow min()/max()/clamp() if the arguments have the same signedness"), which is missing in kernel 5.10.y. In mainline, this change enables min()/max()/clamp() to accept mixed argument types, provided both have the same signedness. Without it, backported patches that use these forms may trigger compiler warnings, which escalate to build failures when -Werror is enabled. Andy Shevchenko (1): minmax: deduplicate __unconst_integer_typeof() David Laight (8): minmax: fix indentation of __cmp_once() and __clamp_once() minmax.h: add whitespace around operators and after commas minmax.h: update some comments minmax.h: reduce the #define expansion of min(), max() and clamp() minmax.h: use BUILD_BUG_ON_MSG() for the lo < hi test in clamp() minmax.h: move all the clamp() definitions after the min/max() ones minmax.h: simplify the variants of clamp() minmax.h: remove some #defines that are only expanded once Herve Codina (1): minmax: Introduce {min,max}_array() Linus Torvalds (8): minmax: avoid overly complicated constant expressions in VM code minmax: make generic MIN() and MAX() macros available everywhere minmax: add a few more MIN_T/MAX_T users minmax: simplify and clarify min_t()/max_t() implementation minmax: simplify min()/max()/clamp() implementation minmax: don't use max() in situations that want a C constant expression minmax: improve macro expansion and type checking minmax: fix up min3() and max3() too Matthew Wilcox (Oracle) (1): minmax: add in_range() macro arch/arm/mm/pageattr.c | 6 +- arch/um/drivers/mconsole_user.c | 2 + arch/x86/mm/pgtable.c | 2 +- drivers/edac/sb_edac.c | 4 +- drivers/edac/skx_common.h | 1 - drivers/gpu/drm/amd/amdgpu/amdgpu.h | 2 + .../drm/amd/display/modules/hdcp/hdcp_ddc.c | 2 + .../drm/amd/pm/powerplay/hwmgr/ppevvmath.h | 14 +- .../amd/pm/swsmu/smu11/sienna_cichlid_ppt.c | 2 + .../drm/arm/display/include/malidp_utils.h | 2 +- .../display/komeda/komeda_pipeline_state.c | 24 +- drivers/gpu/drm/drm_color_mgmt.c | 2 +- drivers/gpu/drm/msm/adreno/a6xx_gmu.c | 6 - drivers/gpu/drm/radeon/evergreen_cs.c | 2 + drivers/hwmon/adt7475.c | 24 +- drivers/input/touchscreen/cyttsp4_core.c | 2 +- drivers/irqchip/irq-sun6i-r.c | 2 +- drivers/md/dm-integrity.c | 4 +- drivers/media/dvb-frontends/stv0367_priv.h | 3 + .../net/ethernet/chelsio/cxgb3/cxgb3_main.c | 18 +- .../net/ethernet/stmicro/stmmac/stmmac_main.c | 2 +- drivers/net/fjes/fjes_main.c | 4 +- drivers/nfc/pn544/i2c.c | 2 - drivers/platform/x86/sony-laptop.c | 1 - drivers/scsi/isci/init.c | 6 +- .../pci/hive_isp_css_include/math_support.h | 5 - drivers/virt/acrn/ioreq.c | 4 +- fs/btrfs/misc.h | 2 - fs/btrfs/tree-checker.c | 2 +- fs/ext2/balloc.c | 2 - fs/ext4/ext4.h | 2 - fs/ufs/util.h | 6 - include/linux/compiler.h | 9 + include/linux/minmax.h | 264 +++++++++++++----- kernel/trace/preemptirq_delay_test.c | 2 - lib/btree.c | 1 - lib/decompress_unlzma.c | 2 + lib/logic_pio.c | 3 - lib/vsprintf.c | 2 +- lib/zstd/zstd_internal.h | 2 - mm/zsmalloc.c | 1 - net/ipv4/proc.c | 2 +- net/ipv6/proc.c | 2 +- net/netfilter/nf_nat_core.c | 6 +- net/tipc/core.h | 2 +- net/tipc/link.c | 10 +- tools/testing/selftests/vm/mremap_test.c | 2 + 47 files changed, 289 insertions(+), 183 deletions(-) -- 2.47.3

[PATCH v 2/2] selftests: riscv: Add test for the Vector ptrace interface

by Yong-Xuan Wang

Add a test case that does some basic verification of the Vector ptrace interface. This forks a child process then using ptrace to inspect and manipulate the v31 register of the child.

[PATCHv3 net 1/2] bonding: fix xfrm offload feature setup on active-backup mode

by Hangbin Liu

The active-backup bonding mode supports XFRM ESP offload. However, when a bond is added using command like `ip link add bond0 type bond mode 1 miimon 100`, the `ethtool -k` command shows that the XFRM ESP offload is disabled. This occurs because, in bond_newlink(), we change bond link first and register bond device later. So the XFRM feature update in bond_option_mode_set() is not called as the bond device is not yet registered, leading to the offload feature not being set successfully. To resolve this issue, we can modify the code order in bond_newlink() to ensure that the bond device is registered first before changing the bond link parameters. This change will allow the XFRM ESP offload feature to be correctly enabled.

[PATCH 1/1] selftest/sched: skip the test if smt is not enabled

by Yifei Liu

The core scheduling is for smt enabled cpus. It is not returns failure and gives plenty of error messages and not clearly points to the smt issue if the smt is disabled. It just mention "not a core sched system" and many other messages.

This helps developers understand why it is skipped and avoids unnecessary attention when running the full selftest suite.

[PATCH v4 0/7] platform/chrome: Fix a possible UAF via revocable

by Tzung-Bi Shih

This is a follow-up series of [1]. It tries to fix a possible UAF in the fops of cros_ec_chardev after the underlying protocol device has gone by using revocable. The 1st patch introduces the revocable which is an implementation of ideas from the talk [2]. The 2nd and 3rd patches add test cases for revocable in Kunit and selftest. The 4th patch converts existing protocol devices to resource providers of cros_ec_device. The 5th - 7th are PoC patches for moving most revocable code to subsystem level. Miscdevice is used as it would be simpler for PoC. Note that the device driver (e.g., cros_ec_chardev) still needs to be revocable-aware. The driver needs to specify where to save the pointer and thus the resource is available in fops. - The 5th patch adds a helper for using revocable API with fops. - The 6th patch leverages the helper in miscdevice. - The 7th patch converts cros_ec_chardev to a resource consumer of cros_ec_device to fix the UAF.

[PATCH net-next 0/8] mptcp: receive path improvement

by Matthieu Baerts (NGI0)

This series includes several changes to the MPTCP RX path. The main goals are improving the RX performances, and increase the long term maintainability. Some changes reflects recent(ish) improvements introduced in the TCP stack: patch 1, 2 and 3 are the MPTCP counter part of SKB deferral free and auto-tuning improvements. Note that patch 3 could possibly fix additional issues, and overall such patch should protect from similar issues to arise in the future. Patches 4-7 are aimed at introducing the socket backlog usage which will be done in a later series to process the packets received by the different subflows while the msk socket is owned. Patch 8 is not related to the RX path, but it contains additional tests for new features recently introduced in net-next. Signed-off-by: Matthieu Baerts (NGI0) <matttbe(a)kernel.org> --- Notes: - Sorry for sending this series that late, we had quite a few patches to upstream during this cycle. This is the last batch, and it has been heavily tested the last 2 weeks. - If there are some issues with some patches, but not with 1-3, it would be nice, if possible, if these 3 first patches can be accepted, to reduce the recently introduced gap with TCP. - Patches can be grouped like this if needed: 1-3, 4-5, 6-7, 8. 6-7 are preparing the ground for future on-going work, they can be dropped if there are issues with them. --- Matthieu Baerts (NGI0) (1): selftests: mptcp: join: validate new laminar endp Paolo Abeni (7): mptcp: leverage skb deferral free tcp: make tcp_rcvbuf_grow() accessible to mptcp code mptcp: rcvbuf auto-tuning improvement mptcp: introduce the mptcp_init_skb helper mptcp: remove unneeded mptcp_move_skb() mptcp: factor out a basic skb coalesce helper mptcp: minor move_skbs_to_msk() cleanup include/net/tcp.h | 1 + net/ipv4/tcp_input.c | 2 +- net/mptcp/protocol.c | 187 ++++++++++++------------ net/mptcp/protocol.h | 4 +- tools/testing/selftests/net/mptcp/mptcp_join.sh | 69 +++++++++ tools/testing/selftests/net/mptcp/pm_nl_ctl.c | 9 ++ 6 files changed, 177 insertions(+), 95 deletions(-) --- base-commit: 1493c18fe8696bfc758a97130a485fc4e08387f5 change-id: 20250927-net-next-mptcp-rcv-path-imp-192d8c24c9c7 Best regards, -- Matthieu Baerts (NGI0) <matttbe(a)kernel.org>
