[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 different hardware, without and with patches: ALL VETH: ========= ./bridge_fastpath.sh -t Setup: CLIENT 0 veth0cl | veth0rt WAN ROUTER LAN1 LAN2 veth1rt veth2rt | | veth1cl veth2cl CLIENT 1 CLIENT 2

[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. The fix is similar to what is done in dynptr_fail.c which is also using bpf_dynptr_slice(): bpf_kfuncs.h is now included. Signed-off-by: Matthieu Baerts (NGI0) <matttbe(a)kernel.org> --- Notes: - This patch looks wrong, I guess bpf_dynptr_slice() should be in vmlinux.h even with a "debug" kernel, but it is not: $ grep -cw bpf_dynptr_slice .virtme/build-debug-btf/tools/include/vmlinux.h 0 $ grep -w bpf_dynptr_slice .virtme/build-btf/tools/include/vmlinux.h extern void *bpf_dynptr_slice(...) __weak __ksym; - This is on top of bpf/master: commit 63d2247e2e37, tag bpf-fixes. - I only see this error when using kernel/configs/debug.config. - Because this has not been spot by the BPF CI, I wonder if I'm building the BPF selftests properly...

[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.

[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
