[PATCHv2 net] Bonding: Fix support for gso_partial_features

by Hangbin Liu

The fixed commit adds NETIF_F_GSO_ESP bit for bonding gso_partial_features. However, if we don't set the dev NETIF_F_GSO_PARTIAL bit, the later netdev_change_features() -> netdev_fix_features() will remove the NETIF_F_GSO_ESP bit from the dev features. This causes ethtool to show that the bond does not support tx-esp-segmentation. For example # ethtool -k bond0 | grep esp tx-esp-segmentation: off [requested on] esp-hw-offload: on esp-tx-csum-hw-offload: on Add the NETIF_F_GSO_PARTIAL bit to bond dev features when set gso_partial_features to fix this issue.

The issue is reported internally, so there is no Closes tag. BTW, I saw some drivers set NETIF_F_GSO_PARTIAL on dev->features. Some other drivers set NETIF_F_GSO_PARTIAL on dev->hw_enc_features.

[PATCH v5 0/3] selftests/lam: get_user additions and LAM enabled check

by Maciej Wieczor-Retman

Recent change in how get_user() handles pointers [1] has a specific case for LAM. It assigns a different bitmask that's later used to check whether a pointer comes from userland in get_user(). While currently commented out (until LASS [2] is merged into the kernel) it's worth making changes to the LAM selftest ahead of time. Modify cpu_has_la57() so it provides current paging level information instead of the cpuid one. Add test case to LAM that utilizes a ioctl (FIOASYNC) syscall which uses get_user() in its implementation. Execute the syscall with differently tagged pointers to verify that valid user pointers are passing through and invalid kernel/non-canonical pointers are not. Also to avoid unhelpful test failures add a check in main() to skip running tests if LAM was not compiled into the kernel. Code was tested on a Sierra Forest Xeon machine that's LAM capable. The test was ran without issues with both the LAM lines from [1] untouched and commented out. The test was also ran without issues with LAM_SUP both enabled and disabled. 4/5 level pagetables code paths were also successfully tested in Simics on a 5-level capable machine.

[PATCH net-next v2 0/5] netconsole: Add support for CPU population

by Breno Leitao

The current implementation of netconsole sends all log messages in parallel, which can lead to an intermixed and interleaved output on the receiving side. This makes it challenging to demultiplex the messages and attribute them to their originating CPUs. As a result, users and developers often struggle to effectively analyze and debug the parallel log output received through netconsole. Example of a message got from produciton hosts: ------------[ cut here ]------------ ------------[ cut here ]------------ refcount_t: saturated; leaking memory. WARNING: CPU: 2 PID: 1613668 at lib/refcount.c:22 refcount_warn_saturate+0x5e/0xe0 refcount_t: addition on 0; use-after-free. WARNING: CPU: 26 PID: 4139916 at lib/refcount.c:25 refcount_warn_saturate+0x7d/0xe0 Modules linked in: bpf_preload(E) vhost_net(E) tun(E) vhost(E) This series of patches introduces a new feature to the netconsole subsystem that allows the automatic population of the CPU number in the userdata field for each log message. This enhancement provides several benefits: * Improved demultiplexing of parallel log output: When multiple CPUs are sending messages concurrently, the added CPU number in the userdata makes it easier to differentiate and attribute the messages to their originating CPUs. * Better visibility into message sources: The CPU number information gives users and developers more insight into which specific CPU a particular log message came from, which can be valuable for debugging and analysis. The changes in this series are as follows: Patch 1: netconsole: Rename userdata to extradata ================================================= Create the a concept of extradata, which encompasses the concept of userdata and the upcoming sysdatao Sysdata is a new concept being added, which is basically fields that are populated by the kernel. At this time only the CPU#, but, there is a desire to add current task name, kernel release version, etc. Patch 2: netconsole: Helper to count number of used entries =========================================================== Create a simple helper to count number of entries in extradata. I am separating this in a function since it will need to count userdata and sysdata. For instance, when the user adds an extra userdata, we need to check if there is space, counting the previous data entries (from userdata and cpu data) Patch 3: netconsole: add support for sysdata and CPU population =============================================================== This is the core patch. Basically add a new option to enable automatic CPU number population in the netconsole userdata Provides a new "cpu_nr" sysfs attribute to control this feature Patch 4: "netconsole: selftest: test CPU number auto-population" ============================================================= Expands the existing netconsole selftest to verify the CPU number auto-population functionality Ensures the received netconsole messages contain the expected "cpu=<CPU>" entry in the message. Test different permutation with userdata Patch 5: "netconsole: docs: Add documentation for CPU number auto-population" ============================================================================= Updates the netconsole documentation to explain the new CPU number auto-population feature Provides instructions on how to enable and use the feature I believe these changes will be a valuable addition to the netconsole subsystem, enhancing its usefulness for kernel developers and users. Signed-off-by: Breno Leitao <leitao(a)debian.org> --- Changes in v2: - Create the concept of extradata and sysdata. This will make the design easier to understand, and the code easier to read. * Basically extradata encompasses userdata and the new sysdata.

[PATCH v2 00/10] x86/module: rework ROX cache to avoid writable copy

by Mike Rapoport

From: "Mike Rapoport (Microsoft)" <rppt(a)kernel.org> Hi, Following Peter's comments [1] these patches rework handling of ROX caches for module text allocations. Instead of using a writable copy that really complicates alternatives patching, temporarily remap parts of a large ROX page as RW for the time of module formation and then restore it's ROX protections when the module is ready. To keep the ROX memory mapped with large pages, make set_memory_rox() capable of restoring large pages (more details are in patch 3). Since this is really about x86, I believe this should go in via tip tree. The patches also available in git https://git.kernel.org/rppt/h/execmem/x86-rox/v9 v2 changes: * only collapse large mappings in set_memory_rox() * simplify RW <-> ROX remapping * don't remove ROX cache pages from the direct map (patch 4) v1: https://lore.kernel.org/all/20241227072825.1288491-1-rppt@kernel.org [1] https://lore.kernel.org/all/20241209083818.GK8562@noisy.programming.kicks-a… Kirill A.

[PATCH net v2] bonding: Correctly support GSO ESP offload

by Cosmin Ratiu

The referenced fix is incomplete. It correctly computes bond_dev->gso_partial_features across slaves, but unfortunately netdev_fix_features discards gso_partial_features from the feature set if NETIF_F_GSO_PARTIAL isn't set in bond_dev->features. This is visible with ethtool -k bond0 | grep esp: tx-esp-segmentation: off [requested on] esp-hw-offload: on esp-tx-csum-hw-offload: on This patch reworks the bonding GSO offload support by: - making aggregating gso_partial_features across slaves similar to the other feature sets (this part is a no-op). - advertising the default partial gso features on empty bond devs, same as with other feature sets (also a no-op). - adding NETIF_F_GSO_PARTIAL to hw_enc_features filtered across slaves. - adding NETIF_F_GSO_PARTIAL to features in bond_setup() With all of these, 'ethtool -k bond0 | grep esp' now reports: tx-esp-segmentation: on esp-hw-offload: on esp-tx-csum-hw-offload: on Fixes: 4861333b4217 ("bonding: add ESP offload features when slaves support") Signed-off-by: Cosmin Ratiu <cratiu(a)nvidia.com> --- drivers/net/bonding/bond_main.c | 19 ++++++++++--------- 1 file changed, 10 insertions(+), 9 deletions(-) diff --git a/drivers/net/bonding/bond_main.c b/drivers/net/bonding/bond_main.c index 7b78c2bada81..e45bba240cbc 100644 --- a/drivers/net/bonding/bond_main.c +++ b/drivers/net/bonding/bond_main.c @@ -1538,17 +1538,20 @@ static netdev_features_t bond_fix_features(struct net_device *dev, NETIF_F_HIGHDMA | NETIF_F_LRO) #define BOND_ENC_FEATURES (NETIF_F_HW_CSUM | NETIF_F_SG | \ - NETIF_F_RXCSUM | NETIF_F_GSO_SOFTWARE) + NETIF_F_RXCSUM | NETIF_F_GSO_SOFTWARE | \ + NETIF_F_GSO_PARTIAL) #define BOND_MPLS_FEATURES (NETIF_F_HW_CSUM | NETIF_F_SG | \ NETIF_F_GSO_SOFTWARE) +#define BOND_GSO_PARTIAL_FEATURES (NETIF_F_GSO_ESP) + static void bond_compute_features(struct bonding *bond) { + netdev_features_t gso_partial_features = BOND_GSO_PARTIAL_FEATURES; unsigned int dst_release_flag = IFF_XMIT_DST_RELEASE | IFF_XMIT_DST_RELEASE_PERM; - netdev_features_t gso_partial_features = NETIF_F_GSO_ESP; netdev_features_t vlan_features = BOND_VLAN_FEATURES; netdev_features_t enc_features = BOND_ENC_FEATURES; #ifdef CONFIG_XFRM_OFFLOAD @@ -1582,8 +1585,9 @@ static void bond_compute_features(struct bonding *bond) BOND_XFRM_FEATURES); #endif /* CONFIG_XFRM_OFFLOAD */ - if (slave->dev->hw_enc_features & NETIF_F_GSO_PARTIAL) - gso_partial_features &= slave->dev->gso_partial_features; + gso_partial_features = netdev_increment_features(gso_partial_features, + slave->dev->gso_partial_features, + BOND_GSO_PARTIAL_FEATURES); mpls_features = netdev_increment_features(mpls_features, slave->dev->mpls_features, @@ -1598,12 +1602,8 @@ static void bond_compute_features(struct bonding *bond) } bond_dev->hard_header_len = max_hard_header_len; - if (gso_partial_features & NETIF_F_GSO_ESP) - bond_dev->gso_partial_features |= NETIF_F_GSO_ESP; - else - bond_dev->gso_partial_features &= ~NETIF_F_GSO_ESP; - done: + bond_dev->gso_partial_features = gso_partial_features; bond_dev->vlan_features = vlan_features; bond_dev->hw_enc_features = enc_features | NETIF_F_GSO_ENCAP_ALL | NETIF_F_HW_VLAN_CTAG_TX | @@ -6046,6 +6046,7 @@ void bond_setup(struct net_device *bond_dev) bond_dev->hw_features |= NETIF_F_GSO_ENCAP_ALL; bond_dev->features |= bond_dev->hw_features; bond_dev->features |= NETIF_F_HW_VLAN_CTAG_TX | NETIF_F_HW_VLAN_STAG_TX; + bond_dev->features |= NETIF_F_GSO_PARTIAL; #ifdef CONFIG_XFRM_OFFLOAD bond_dev->hw_features |= BOND_XFRM_FEATURES; /* Only enable XFRM features if this is an active-backup config */ -- 2.45.0

[PATCH bpf-next v2 00/10] selftests/bpf: Migrate test_xdp_redirect_multi.sh to test_progs

by Bastien Curutchet (eBPF Foundation)

Hi all, This patch series continues the work to migrate the *.sh tests into prog_tests framework. test_xdp_redirect_multi.sh tests the XDP redirections done through bpf_redirect_map(). This is already partly covered by test_xdp_veth.c that already tests map redirections at XDP level. What isn't covered yet by test_xdp_veth is the use of the broadcast flags (BPF_F_BROADCAST or BPF_F_EXCLUDE_INGRESS) and XDP egress programs. Hence, this patch series add test cases to test_xdp_veth.c to get rid of the test_xdp_redirect_multi.sh: - PATCH 1 to 5 rework test_xdp_veth to make it more generic and allow to configure different test cases - PATCH 6 adds test cases for 'classic' bpf_redirect_map() - PATCH 7 & 8 covers the broadcast flags - PATCH 9 covers the XDP egress programs - PATCH 10 removes test_xdp_redirect_multi.sh Signed-off-by: Bastien Curutchet (eBPF Foundation) <bastien.curutchet(a)bootlin.com> --- Changes in v2: - Use serial_test_* to avoid conflict between tests - Link to v1: https://lore.kernel.org/r/20250121-redirect-multi-v1-0-b215e35ff505@bootlin… --- Bastien Curutchet (eBPF Foundation) (10): selftests/bpf: test_xdp_veth: Split network configuration selftests/bpf: Remove unused argument selftests/bpf: test_xdp_veth: Rename config[] selftests/bpf: test_xdp_veth: Add prog_config[] table selftests/bpf: test_xdp_veth: Add XDP flags to prog_configuration selftests/bpf: test_xdp_veth: Add new test cases for XDP flags selftests/bpf: Optionally select broadcasting flags selftests/bpf: test_xdp_veth: Add XDP broadcast redirection tests selftests/bpf: test_xdp_veth: Add XDP program on egress test selftests/bpf: Remove test_xdp_redirect_multi.sh tools/testing/selftests/bpf/Makefile | 2 - .../selftests/bpf/prog_tests/test_xdp_veth.c | 534 +++++++++++++++++---- .../testing/selftests/bpf/progs/xdp_redirect_map.c | 89 ++++ .../selftests/bpf/progs/xdp_redirect_multi_kern.c | 41 +- .../selftests/bpf/test_xdp_redirect_multi.sh | 214 --------- tools/testing/selftests/bpf/xdp_redirect_multi.c | 226 --------- 6 files changed, 553 insertions(+), 553 deletions(-) --- base-commit: 349e0551b929b4712b4d6127f67dfa41ed48d5a2 change-id: 20250103-redirect-multi-245d6eafb5d1 Best regards, -- Bastien Curutchet (eBPF Foundation) <bastien.curutchet(a)bootlin.com>
