[PATCH net-next 0/5] net: common feature compute for upper interface

by Hangbin Liu

Some high-level virtual drivers need to compute features from their lower devices, but each currently has its own implementation and may miss some feature computations. This patch set introduces a common function to compute features for such devices. Currently, bonding, team, and bridge have been updated to use the new helper. Hangbin Liu (5): net: add a common function to compute features from lowers devices bonding: use common function to compute the features team: use common function to compute the features net: bridge: use common function to compute the features selftests/net: add offload checking test for virtual interface drivers/net/bonding/bond_main.c | 99 +---------- drivers/net/team/team_core.c | 73 +------- include/linux/netdevice.h | 19 +++ net/bridge/br_if.c | 22 +-- net/core/dev.c | 79 +++++++++ tools/testing/selftests/net/config | 2 + tools/testing/selftests/net/vdev_offload.sh | 174 ++++++++++++++++++++ 7 files changed, 285 insertions(+), 183 deletions(-) create mode 100755 tools/testing/selftests/net/vdev_offload.sh -- 2.50.1

[PATCHv5 iproute2-next] iplink: bond_slave: add support for actor_port_prio

by Hangbin Liu

Add support for the actor_port_prio option for bond slaves. This per-port priority can be used by the bonding driver in ad_select to choose the higher-priority aggregator during failover.

[PATCH v2 0/1] seccomp: Add SECCOMP_CLONE_FILTER operation

by Tom Hromatka

Add an operation, SECCOMP_CLONE_FILTER, that can copy the seccomp filters from another process to the current process. Changes from v1 to v2: * Fixed locking issues. Thanks Al, Alexei, and Kees :) * Allow filters to be cloned if CAP_SYS_ADMIN or no new privs is set * I initially had only CAP_SYS_ADMIN, but I can't think of a way no new privs is harmful here, so I added it. Thanks, Kees * Switch to passing in pidfd directly rather than a pointer to a pidfd * This more closely aligns with other pidfd syscalls * Fixed warning in the sample code reported by the test robot * Various cleanups and improvements in the selftest Note that I left in the restriction that the target process has no seccomp filters already loaded. I could see this limitation being removed in a later patchset, but there are requests for this feature at present. Finally, I re-ran the performance numbers and updated the patch with the latest numbers. The locking changes significantly sped up the clone operation, and it's now ~1900x faster than the current method.

[PATCH net-next v3] selftests: net: Add tests to verify team driver option set and get.

by Marc Harvey

There are currently no kernel tests that verify setting and getting options of the team driver. In the future, options may be added that implicitly change other options, which will make it useful to have tests like these that show nothing breaks. There will be a follow up patch to this that adds new "rx_enabled" and "tx_enabled" options, which will implicitly affect the "enabled" option value and vice versa. The tests use teamnl to first set options to specific values and then gets them to compare to the set values.

The write() and read() system calls in ksft_ready() and ksft_wait() functions return values that were not being checked, causing complier warnings with GCC.

[PATCH v1] selftests/mm: gup_tests: option to GUP all pages in a single call

by David Hildenbrand

We recently missed detecting an issue during early testing because the default (!all) tests would not trigger it and even when running "all" tests it only would happen sometimes because of races. So let's allow for an easy way to specify "GUP all pages in a single call", extend the test matrix and extend our default (!all) tests. By GUP'ing all pages in a single call, with the default size of 128MiB we'll cover multiple leaf page tables / PMDs on architectures with sane THP sizes.

They come as part > of an SoC. "Yes and no. The problem is that the EP implementation is meant to be a generic library and while GIC-ITS guarantees immutability of the address/data pair after setup, there are architectures (x86, loongson, riscv) where the base MSI controller does not and immutability is only achieved when interrupt remapping is enabled. The latter can be disabled at boot-time and then the EP implementation becomes a lottery across affinity changes. That was my concern about this library implementation and that's why I asked for a mechanism to ensure that the underlying irqdomain provides a immutable address/data pair. So it does not matter for GIC-ITS, but in the larger picture it matters. Thanks, tglx " So it does not matter for GIC-ITS, but in the larger picture it matters. - Link to v15: https://lore.kernel.org/r/20250211-ep-msi-v15-0-bcacc1f2b1a9@nxp.com Changes in v15: - rebase to v6.14-rc1 - fix build issue find by kernel test robot - Link to v14: https://lore.kernel.org/r/20250207-ep-msi-v14-0-9671b136f2b8@nxp.com Changes in v14: Marc Zyngier raised concerns about adding DOMAIN_BUS_DEVICE_PCI_EP_MSI. As a result, the approach has been reverted to the v9 method. However, there are several improvements: MSI now supports msi-map in addition to msi-parent. - The struct device: id is used as the endpoint function (EPF) device identity to map to the stream ID (sideband information). - The EPC device tree source (DTS) utilizes msi-map to provide such information. - The EPF device's of_node is set to the EPC controller’s node. This approach is commonly used for multi-function device (MFD) platform child devices, allowing them to inherit properties from the MFD device’s DTS, such as reset-cells and gpio-cells. This method is well-suited for the current case, as the EPF is inherently created/binded to the EPC and should inherit the EPC’s DTS node properties. Additionally: Since the basic IMX95 LUT support has already been merged into the mainline, a DTS and driver increment patch is added to complete the solution. The patch is rebased onto the latest linux-next tree and aligned with the new pcitest framework. - Link to v13: https://lore.kernel.org/r/20241218-ep-msi-v13-0-646e2192dc24@nxp.com Changes in v13: - Change to use DOMAIN_BUS_PCI_DEVICE_EP_MSI - Change request id as func | vfunc << 3 - Remove IRQ_DOMAIN_MSI_IMMUTABLE Thomas Gleixner: I hope capture all your points in review comments.

[PATCH net 0/3] mptcp: misc fixes for v6.17-rc6

by Matthieu Baerts (NGI0)

Here are various unrelated fixes: - Patch 1: Fix a wrong attribute type in the MPTCP Netlink specs. A fix for v6.7. - Patch 2: Avoid mentioning a deprecated MPTCP sysctl knob in the doc. A fix for v6.15. - Patch 3: Handle new warnings from ShellCheck v0.11.0. This prevents some warnings reported by some CIs. If it is not a good material for 'net', please drop it and I can resend it later, targeting 'net-next'.

[PATCH net-next v2] selftests: net: replace sleeps in fcnal-test with waits

by Jakub Kicinski

fcnal-test.sh already includes lib.sh, use relevant helpers instead of sleeping. The first chunk is replacing sleep after killing background commands. All remaining ones replace sleep after starting nettest as a server with wait_local_port_listen.

[PATCHv2 1/2] bonding: don't set oif to bond dev when getting NS target destination

by Hangbin Liu

Unlike IPv4, IPv6 routing strictly requires the source address to be valid on the outgoing interface. If the NS target is set to a remote VLAN interface, and the source address is also configured on a VLAN over a bond interface, setting the oif to the bond device will fail to retrieve the correct destination route. Fix this by not setting the oif to the bond device when retrieving the NS target destination. This allows the correct destination device (the VLAN interface) to be determined, so that bond_verify_device_path can return the proper VLAN tags for sending NS messages.

[PATCH net 1/2] bonding: set random address only when slaves already exist

by Hangbin Liu

Commit 5c3bf6cba791 ("bonding: assign random address if device address is same as bond") fixed an issue where, after releasing the first slave and re-adding it to the bond with fail_over_mac=follow, both the active and backup slaves could end up with duplicate MAC addresses. To avoid this, the new slave was assigned a random address. However, if this happens when adding the very first slave, the bond’s hardware address is set to match the slave’s. Later, during the fail_over_mac=follow check, the slave’s MAC is randomized because it naturally matches the bond, which is incorrect. The issue is normally hidden since the first slave usually becomes the active one, which restores the bond's MAC address. However, if another slave is selected as the initial active interface, the issue becomes visible. Fix this by assigning a random address only when slaves already exist in the bond.

[PATCH net-next] selftests: net: speed up pmtu.sh by avoiding unnecessary cleanup

by Jakub Kicinski

The pmtu test takes nearly an hour when run on a debug kernel (10min on a normal kernel, so the debug slow down is quite significant). NIPA tries to ensure all results are delivered by a certain deadline so this prevents it from retrying the test in case of a flake. Looks like one of the slowest operations in the test is calling out to ./openvswitch/ovs-dpctl.py to remove potential leftover OvS interfaces. Check whether the interfaces exist in the first place in sysfs, since it can be done directly in bash it is very fast. This should save us around 20-30% of the test runtime.

[PATCH RFC net-next 0/5] selftests: drv-net: Convert XDP program to bpf_dynptr

by Nimrod Oren

Hi all, This series updates the drv-net XDP program used by the new xdp.py selftest to use the bpf_dynptr APIs for packet access. The selftest itself is unchanged. The original program accessed packet headers directly via ctx->data/data_end, implicitly assuming headers are always in the linear region. That assumption is incorrect for multi-buffer XDP and does not hold across all drivers. For example, mlx5 with striding RQ can leave the linear area empty, causing the multi-buffer cases to fail. Switching to bpf_xdp_load/store_bytes would work but always incurs copies. Instead, this series adopts bpf_dynptr, which provides safe, verifier-checked access across both linear and fragmented areas while avoiding copies. Amery Hung has also proposed a series [1] that addresses the same issues in the program, but through the use of bpf_xdp_pull_data. My series is not intended as a replacement for that work, but rather as an exploration of another viable solution, each of which may be preferable under different circumstances. In cases where the program does not return XDP_PASS, I believe dynptr has an advantage since it avoids an extra copy. Conversely, when the program returns XDP_PASS, bpf_xdp_pull_data may be preferable, as the copy will be performed in any case during skb creation. It may make sense to split the work into two separate programs, allowing us to test both solutions independently. Alternatively, we can consider a combined approach, where the more fitting solution is applied for each use case. I welcome feedback on which direction would be most useful.

[PATCH bpf-next v2] selftests/bpf: Fix incorrect array size calculation

by Jiayuan Chen

The loop in bench_sockmap_prog_destroy() has two issues: 1. Using 'sizeof(ctx.fds)' as the loop bound results in the number of bytes, not the number of file descriptors, causing the loop to iterate far more times than intended. 2. The condition 'ctx.fds[0] > 0' incorrectly checks only the first fd for all iterations, potentially leaving file descriptors unclosed. Change it to 'ctx.fds[i] > 0' to check each fd properly. These fixes ensure correct cleanup of all file descriptors when the benchmark exits.

[PATCH net-next v6] selftests: net: add test for ipv6 fragmentation

by Brett A C Sheffield

Add selftest for the IPv6 fragmentation regression which affected several stable kernels. Commit a18dfa9925b9 ("ipv6: save dontfrag in cork") was backported to stable without some prerequisite commits. This caused a regression when sending IPv6 UDP packets by preventing fragmentation and instead returning -1 (EMSGSIZE). Add selftest to check for this issue by attempting to send a packet larger than the interface MTU.

[PATCHv5 net-next 0/3] bonding: support aggregator selection based on port priority

by Hangbin Liu

This patchset introduces a new per-port bonding option: `ad_actor_port_prio`. It allows users to configure the actor's port priority, which can then be used by the bonding driver for aggregator selection based on port priority. This provides finer control over LACP aggregator choice, especially in setups with multiple eligible aggregators over 2 switches. v5: a) rename 'prio' to 'actor_port_prio' in bond_ad_select_tbl (Jay Vosburgh) b) update document description v4: a) fix actor_port_prio minimal value (Jay Vosburgh) b) fix ad_agg_selection_test comment order (Paolo Abeni) c) restruct selftest, reduce duplication (Paolo Abeni) v3: a) add comments when init slave port_priority (Jonas Gorski) b) rename ad_lacp_port_prio to lacp_port_prio (Jay Vosburgh) v2: a) set default bond option value for port priority (Nikolay Aleksandrov) b) fix __agg_ports_priority coding style (Nikolay Aleksandrov) c) fix shellcheck warns Hangbin Liu (3): bonding: add support for per-port LACP actor priority bonding: support aggregator selection based on port priority selftests: bonding: add test for LACP actor port priority Documentation/networking/bonding.rst | 25 +++- drivers/net/bonding/bond_3ad.c | 31 +++++ drivers/net/bonding/bond_netlink.c | 16 +++ drivers/net/bonding/bond_options.c | 45 +++++++- include/net/bond_3ad.h | 2 + include/net/bond_options.h | 1 + include/uapi/linux/if_link.h | 1 + .../selftests/drivers/net/bonding/Makefile | 3 +- .../drivers/net/bonding/bond_lacp_prio.sh | 108 ++++++++++++++++++ tools/testing/selftests/net/forwarding/lib.sh | 24 ---- tools/testing/selftests/net/lib.sh | 24 ++++ 11 files changed, 247 insertions(+), 33 deletions(-) create mode 100755 tools/testing/selftests/drivers/net/bonding/bond_lacp_prio.sh -- 2.50.1

Some high-level virtual drivers need to compute features from their lower devices, but each currently has its own implementation and may miss some feature computations. This patch set introduces a common function to compute features for such devices. Currently, bonding, team, and bridge have been updated to use the new helper. v2: a) remove hard_header_len setting. I will set needed_headroom for bond/team in a separate patch as bridge has it's own ways. (Ido Schimmel) b) Add test file to Makefile, set RET=0 to a proper location.

[PATCH 0/5] KVM: Improve nested VMX performance

by Fred Griffoul

From: Fred Griffoul <griffoul(a)casper.infradead.org> This patch series addresses performance issues in nested VMX when handling unmanaged guest memory. Unmanaged guest memory refers to memory not directly mapped by the kernel (no struct page), such as memory passed with the mem= parameter or guest_memfd for non-Confidential Computing (CoCo) VMs. Current Problem: During nested VMX operations, the system frequently accesses specific guest pages during L2 VM entry/exit cycles. The current workflow: 1. kvm_vcpu_map() invokes memremap() for unmanaged memory. 2. The system either directly accesses mapped memory via nested VMX or passes it to the L2 guest through vmcs02. 3. kvm_vcpu_unmap() invokes memunmap() This repeated map/unmap cycle creates significant performance overhead due to expensive remapping operations. Solution approach: Our solution replaces kvm_host_map with gfn_to_pfn_cache in nested VMX. It addresses two distinct types of guest pages. First, we handle the L1 MSR bitmap page, which requires read-only access for folding L1 and L0 MSR bitmap. We implement this conversion to gfn_to_pfn_cache in patch 1. Second, we tackle system pages, including APIC access, virtual APIC, and posted interrupt descriptor pages. These pages are more complex as they're accessed by both nested VMX code _and_ passed to the L2 guest in vmcs02 fields. This requires to restore and complete the "guest-uses-pfn" support in pfncache through patches 2 and 3, followed by implementing kvm_host_map replacement with caches in patch 4. Testing: Patch 5 introduces a new selftest to verify cache invalidation and memslot update functionality.

[PATCH v15 0/6] KVM: arm64: Provide guest support for GCS

by Mark Brown

The arm64 Guarded Control Stack (GCS) feature provides support for hardware protected stacks of return addresses, intended to provide hardening against return oriented programming (ROP) attacks and to make it easier to gather call stacks for applications such as profiling. When GCS is active a secondary stack called the Guarded Control Stack is maintained, protected with a memory attribute which means that it can only be written with specific GCS operations. The current GCS pointer can not be directly written to by userspace. When a BL is executed the value stored in LR is also pushed onto the GCS, and when a RET is executed the top of the GCS is popped and compared to LR with a fault being raised if the values do not match. GCS operations may only be performed on GCS pages, a data abort is generated if they are not. The combination of hardware enforcement and lack of extra instructions in the function entry and exit paths should result in something which has less overhead and is more difficult to attack than a purely software implementation like clang's shadow stacks. This series implements support for managing GCS for KVM guests, it also includes a fix for S1PIE which has also been sent separately as this feature is a dependency for GCS.

[PATCH v3 bpf-next] selftests/bpf: Fix the issue where the error code is 0

by Feng Yang

From: Feng Yang <yangfeng(a)kylinos.cn> The error message printed here only uses the previous err value, which results in it being printed as 0. When bpf_map__attach_struct_ops encounters an error, it uses libbpf_err_ptr(err) to set errno = -err and returns NULL. Therefore, Using -errno can fix this issue. Fix before: run_subtest:FAIL:1019 bpf_map__attach_struct_ops failed for map pro_epilogue: err=0 Fix after: run_subtest:FAIL:1019 bpf_map__attach_struct_ops failed for map pro_epilogue: err=-9 Signed-off-by: Feng Yang <yangfeng(a)kylinos.cn> --- Changes in v3: - Use -errno here directly, thanks: Andrii Nakryiko. - Link to v2: https://lore.kernel.org/all/20250829014125.198653-1-yangfeng59949@163.com/ --- Changes in v2: - Use libbpf_get_error, thanks: Alexei Starovoitov. - Link to v1: https://lore.kernel.org/all/20250828081507.1380218-1-yangfeng59949@163.com/ --- tools/testing/selftests/bpf/test_loader.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/bpf/test_loader.c b/tools/testing/selftests/bpf/test_loader.c index 78423cf89e01..33d59c093a27 100644 --- a/tools/testing/selftests/bpf/test_loader.c +++ b/tools/testing/selftests/bpf/test_loader.c @@ -1083,7 +1083,7 @@ void run_subtest(struct test_loader *tester, link = bpf_map__attach_struct_ops(map); if (!link) { PRINT_FAIL("bpf_map__attach_struct_ops failed for map %s: err=%d\n", - bpf_map__name(map), err); + bpf_map__name(map), -errno); goto tobj_cleanup; } links[links_cnt++] = link; -- 2.25.1

[PATCH] selftests/filesystems: Use return value of the function 'chdir()'

by Alessandro Zanni

Fix to use the return value of the function 'chdir("/")' and check if the return is either 0 (ok) or 1 (not ok, so the test stops). The patch fies the solves the following errors: mount-notify_test.c:468:17: warning: ignoring return value of ‘chdir’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 468 | chdir("/"); mount-notify_test_ns.c:489:17: warning: ignoring return value of ‘chdir’ declared with attribute ‘warn_unused_result’ [-Wunused- result] 489 | chdir("/"); To reproduce the issue, use the command: make kselftest TARGET=filesystems/statmount Signed-off-by: Alessandro Zanni <alessandro.zanni87(a)gmail.com> --- .../selftests/filesystems/mount-notify/mount-notify_test.c | 2 +- .../selftests/filesystems/mount-notify/mount-notify_test_ns.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/filesystems/mount-notify/mount-notify_test.c b/tools/testing/selftests/filesystems/mount-notify/mount-notify_test.c index 5a3b0ace1a88..a7f899599d52 100644 --- a/tools/testing/selftests/filesystems/mount-notify/mount-notify_test.c +++ b/tools/testing/selftests/filesystems/mount-notify/mount-notify_test.c @@ -458,7 +458,7 @@ TEST_F(fanotify, rmdir) ASSERT_GE(ret, 0); if (ret == 0) { - chdir("/"); + ASSERT_EQ(0, chdir("/")); unshare(CLONE_NEWNS); mount("", "/", NULL, MS_REC|MS_PRIVATE, NULL); umount2("/a", MNT_DETACH); diff --git a/tools/testing/selftests/filesystems/mount-notify/mount-notify_test_ns.c b/tools/testing/selftests/filesystems/mount-notify/mount-notify_test_ns.c index d91946e69591..dc9eb3087a1a 100644 --- a/tools/testing/selftests/filesystems/mount-notify/mount-notify_test_ns.c +++ b/tools/testing/selftests/filesystems/mount-notify/mount-notify_test_ns.c @@ -486,7 +486,7 @@ TEST_F(fanotify, rmdir) ASSERT_GE(ret, 0); if (ret == 0) { - chdir("/"); + ASSERT_EQ(0, chdir("/")); unshare(CLONE_NEWNS); mount("", "/", NULL, MS_REC|MS_PRIVATE, NULL); umount2("/a", MNT_DETACH); -- 2.43.0
