[PATCH 0/2] fix reading ESP during coredump

by Nam Cao

Hi, In /proc/PID/stat, there is the kstkesp field which is the stack pointer of a thread. While the thread is active, this field reads zero. But during a coredump, it should have a valid value. However, at the moment, kstkesp is zero even during coredump. The first commit fixes this problem, and the second commit adds a selftest to detect if this problem appears again in the future.

[PATCH RFC net-next v1 0/5] Device memory TCP TX

by Mina Almasry

The TX path had been dropped from the Device Memory TCP patch series post RFCv1 [1], to make that series slightly easier to review. This series rebases the implementation of the TX path on top of the net_iov/netmem framework agreed upon and merged. The motivation for the feature is thoroughly described in the docs & cover letter of the original proposal, so I don't repeat the lengthy descriptions here, but they are available in [1]. Sending this series as RFC as the winder closure is immenient. I plan on reposting as non-RFC once the tree re-opens, addressing any feedback I receive in the meantime. Full outline on usage of the TX path is detailed in the documentation added in the first patch. Test example is available via the kselftest included in the series as well. The series is relatively small, as the TX path for this feature largely piggybacks on the existing MSG_ZEROCOPY implementation. Patch Overview: --------------- 1. Documentation & tests to give high level overview of the feature being added. 2. Add netmem refcounting needed for the TX path. 3. Devmem TX netlink API. 4. Devmem TX net stack implementation. Testing: -------- Testing is very similar to devmem TCP RX path. The ncdevmem test used for the RX path is now augemented with client functionality to test TX path. * Test Setup: Kernel: net-next with this RFC and memory provider API cherry-picked locally. Hardware: Google Cloud A3 VMs. NIC: GVE with header split & RSS & flow steering support. Performance results are not included with this version, unfortunately. I'm having issues running the dma-buf exporter driver against the upstream kernel on my test setup. The issues are specific to that dma-buf exporter and do not affect this patch series. I plan to follow up this series with perf fixes if the tests point to issues once they're up and running. Special thanks to Stan who took a stab at rebasing the TX implementation on top of the netmem/net_iov framework merged. Parts of his proposal [2] that are reused as-is are forked off into their own patches to give full credit.

[PATCH bpf] selftests/bpf: add XDP_UMEM_TX_METADATA_LEN flag to umem_config

by Wei Fang

The Tx metadata test has been broken since the commit d5e726d9143c ("xsk: Require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len"). Because this change requires XDP_UMEM_TX_METADATA_LEN flag to be set, otherwise xsk_buff_pool::tx_metadata_len will be initialized to 0, which means that the driver cannot get Tx metadata and cannot execute AF_XDP Tx metadata hooks.

[PATCH AUTOSEL 6.12 29/29] bpf: consider that tail calls invalidate packet pointers

by Sasha Levin

From: Eduard Zingerman <eddyz87(a)gmail.com> [ Upstream commit 1a4607ffba35bf2a630aab299e34dd3f6e658d70 ] Tail-called programs could execute any of the helpers that invalidate packet pointers. Hence, conservatively assume that each tail call invalidates packet pointers. Making the change in bpf_helper_changes_pkt_data() automatically makes use of check_cfg() logic that computes 'changes_pkt_data' effect for global sub-programs, such that the following program could be rejected: int tail_call(struct __sk_buff *sk) { bpf_tail_call_static(sk, &jmp_table, 0); return 0; } SEC("tc") int not_safe(struct __sk_buff *sk) { int *p = (void *)(long)sk->data; ... make p valid ... tail_call(sk); *p = 42; /* this is unsafe */ ... } The tc_bpf2bpf.c:subprog_tc() needs change: mark it as a function that can invalidate packet pointers. Otherwise, it can't be freplaced with tailcall_freplace.c:entry_freplace() that does a tail call.

[PATCH RFC v3 00/27] KVM: arm64: Implement support for SME in non-protected guests

by Mark Brown

Given the time of year and point in the release cycle this is an RFC series, there's a few areas where I'm particularly expecting that people might have feedback: - The userspace ABI, in particular: - The vector length used for the SVE registers, access to the SVE registers and access to ZA and (if available) ZT0 depending on the current state of PSTATE.{SM,ZA}. - The use of a single finalisation for both SVE and SME. - The addition of control for enabling fine grained traps in a similar manner to FGU but without the UNDEF, I'm not clear if this is desired at all and at present this requires symmetric read and write traps like FGU. That seemed like it might be desired from an implementation point of view but we already have one case where we enable an asymmetric trap (for ARM64_WORKAROUND_AMPERE_AC03_CPU_38) and it seems generally useful to enable asymmetrically. There is some nested virtualisation support in the code but it is not enabled or complete, this will be completed before the RFC tag is removed. I am anticipating having a vastly better test environment soon which will make this much easier to complete and there is no SME specific ABI for nested virtualisation. This series implements support for SME use in non-protected KVM guests. Much of this is very similar to SVE, the main additional challenge that SME presents is that it introduces a new vector length similar to the SVE vector length and two new controls which change the registers seen by guests: - PSTATE.ZA enables the ZA matrix register and, if SME2 is supported, the ZT0 LUT register. - PSTATE.SM enables streaming mode, a new floating point mode which uses the SVE register set with the separately configured SME vector length. In streaming mode implementation of the FFR register is optional. It is also permitted to build systems which support SME without SVE, in this case when not in streaming mode no SVE registers or instructions are available. Further, there is no requirement that there be any overlap in the set of vector lengths supported by SVE and SME in a system, this is expected to be a common situation in practical systems. Since there is a new vector length to configure we introduce a new feature parallel to the existing SVE one with a new pseudo register for the streaming mode vector length. Due to the overlap with SVE caused by streaming mode rather than finalising SME as a separate feature we use the existing SVE finalisation to also finalise SME, a new define KVM_ARM_VCPU_VEC is provided to help make user code clearer. Finalising SVE and SME separately would introduce complication with register access since finalising SVE makes the SVE regsiters writeable by userspace and doing multiple finalisations results in an error being reported. Dealing with a state where the SVE registers are writeable due to one of SVE or SME being finalised but may have their VL changed by the other being finalised seems like needless complexity with minimal practical utility, it seems clearer to just express directly that only one finalisation can be done in the ABI. Access to the floating point registers follows the architecture: - When both SVE and SME are present: - If PSTATE.SM == 0 the vector length used for the Z and P registers is the SVE vector length. - If PSTATE.SM == 1 the vector length used for the Z and P registers is the SME vector length. - If only SME is present: - If PSTATE.SM == 0 the Z and P registers are inaccessible and the floating point state accessed via the encodings for the V registers. - If PSTATE.SM == 1 the vector length used for the Z and P registers - The SME specific ZA and ZT0 registers are only accessible if SVCR.ZA is 1. The VMM must understand this, in particular when loading state SVCR should be configured before other state. There are a large number of subfeatures for SME, most of which only offer additional instructions but some of which (SME2 and FA64) add architectural state. These are configured via the ID registers as per usual. The new KVM_ARM_VCPU_VEC feature and ZA and ZT0 registers have not been added to the get-reg-list selftest, the idea of supporting additional features there without restructuring the program to generate all possible feature combinations has been rejected. I will post a separate series which does that restructuring. No support is present for protected guests, this is expected to be added separately.

[PATCH v6 0/2] kselftest: tmpfs: Add ksft macros and skip if no root

by Shivam Chaudhary

This version 5 patch series replace direct error handling methods with ksft macros, which provide better reporting.Currently, when the tmpfs test runs, it does not display any output if it passes,and if it fails (particularly when not run as root),it simply exits without any warning or message. This series of patch adds: 1. Add 'ksft_print_header()' and 'ksft_set_plan()' to structure test outputs more effectively. 2. skip if not run as root. 3. Replace direct error handling with 'ksft_test_result_*', macros for better reporting. v5->v6: - Skip if not run as root. v5 v1: https://lore.kernel.org/all/20241112143056.565122-2-cvam0000@gmail.com/ v5 v2: https://lore.kernel.org/all/20241112143056.565122-3-cvam0000@gmail.com/ v4->v5: - Remove unnecessary pass messages. - Remove unnecessary use of KSFT_SKIP. - Add appropriate use of ksft_exit_fail_msg. v4 v1: https://lore.kernel.org/all/8db9feab-0600-440b-b4b2-042695a100b5@linuxfound… v4 v2: https://lore.kernel.org/all/63d5e3bb-9817-4a34-98fe-823a9cac7c16@linuxfound… v3->v4: - Start a patchset - Split patch into smaller patches to make it easy to review. Patch1 Replace 'ksft_test_result_skip' with 'KSFT_SKIP' during root run check.
