selftests/bpf: Remove entries from config.{arch} already present in config

2025-08-26T11:47:03Z

`config.{arch}` had entries already present in `config`. When generating the config used by vmtest, concatenate the `config` file with the `config.{arch}` one, making those entries duplicated, so remove those duplications. Use the following command to get the differences: $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.x86_64) <(sort tools/testing/selftests/bpf/config) $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.aarch64) <(sort tools/testing/selftests/bpf/config) $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.riscv64) <(sort tools/testing/selftests/bpf/config) $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.ppc64el) <(sort tools/testing/selftests/bpf/config) $ comm -1 -2 <(sort tools/testing/selftests/bpf/config.s390x) <(sort tools/testing/selftests/bpf/config) This is similar with commit 7a42af4b94f1 ("selftests/bpf: Remove entries from config.s390x already present in config").

fs: remove uselib() system call

2025-04-21T08:27:59Z

This system call has been deprecated for quite a while now. Let's try and remove it from the kernel completely. Link: https://lore.kernel.org/20250415-kanufahren-besten-02ac00e6becd@brauner Acked-by: Kees Cook Signed-off-by: Christian Brauner

bpfilter: remove bpfilter

2024-01-04T18:23:10Z

bpfilter was supposed to convert iptables filtering rules into BPF programs on the fly, from the kernel, through a usermode helper. The base code for the UMH was introduced in 2018, and couple of attempts (2, 3) tried to introduce the BPF program generate features but were abandoned. bpfilter now sits in a kernel tree unused and unusable, occasionally causing confusion amongst Linux users (4, 5). As bpfilter is now developed in a dedicated repository on GitHub (6), it was suggested a couple of times this year (LSFMM/BPF 2023, LPC 2023) to remove the deprecated kernel part of the project. This is the purpose of this patch.

selftests/bpf: Disable CONFIG_DEBUG_INFO_REDUCED in config.aarch64

2023-11-10T03:07:38Z

Building an arm64 kernel and seftests/bpf with defconfig + selftests/bpf/config and selftests/bpf/config.aarch64 the fragment CONFIG_DEBUG_INFO_REDUCED is enabled in arm64's defconfig, it should be disabled in file sefltests/bpf/config.aarch64 since if its not disabled CONFIG_DEBUG_INFO_BTF wont be enabled.

selftests/bpf: Consolidate VIRTIO/9P configs in config.vm file

2023-11-10T03:07:38Z

Those configs are needed to be able to run VM somewhat consistently. For instance, ATM, s390x is missing the `CONFIG_VIRTIO_CONSOLE` which prevents s390x kernels built in CI to leverage qemu-guest-agent. By moving them to `config,vm`, we should have selftest kernels which are equal in term of VM functionalities when they include this file. The set of config unabled were picked using grep -h -E '(_9P|_VIRTIO)' config.x86_64 config | sort | uniq added to `config.vm` and then grep -vE '(_9P|_VIRTIO)' config.{x86_64,aarch64,s390x} as a side-effect, some config may have disappeared to the aarch64 and s390x kernels, but they should not be needed. CI will tell. Signed-off-by: Manu Bretelle Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20231031212717.4037892-1-chantr4@gmail.com Signed-off-by: Alexei Starovoitov
