Ilya Leoshkevich says: ==================== v2: https://lore.kernel.org/bpf/20230128000650.1516334-1-iii@linux.ibm.com/#t v2 -> v3: - Make __arch_prepare_bpf_trampoline static. (Reported-by: kernel test robot <lkp@intel.com>) - Support both old- and new- style map definitions in sk_assign. (Alexei) - Trim DENYLIST.s390x. (Alexei) - Adjust s390x vmlinux path in vmtest.sh. - Drop merged fixes. v1: https://lore.kernel.org/bpf/20230125213817.1424447-1-iii@linux.ibm.com/#t v1 -> v2: - Fix core_read_macros, sk_assign, test_profiler, test_bpffs (24/31; I'm not quite happy with the fix, but don't have better ideas), and xdp_synproxy. (Andrii) - Prettify liburandom_read and verify_pkcs7_sig fixes. (Andrii) - Fix bpf_usdt_arg using barrier_var(); prettify barrier_var(). (Andrii) - Change BPF_MAX_TRAMP_LINKS to enum and query it using BTF. (Andrii) - Improve bpf_jit_supports_kfunc_call() description. (Alexei) - Always check sign_extend() return value. - Cc: Alexander Gordeev. Hi, This series implements poke, trampoline, kfunc, and mixing subprogs and tailcalls on s390x. The following failures still remain: #82 get_stack_raw_tp:FAIL get_stack_print_output:FAIL:user_stack corrupted user stack Known issue: We cannot reliably unwind userspace on s390x without DWARF. #101 ksyms_module:FAIL address of kernel function bpf_testmod_test_mod_kfunc is out of range Known issue: Kernel and modules are too far away from each other on s390x. #190 stacktrace_build_id:FAIL Known issue: We cannot reliably unwind userspace on s390x without DWARF. #281 xdp_metadata:FAIL See patch 6. None of these seem to be due to the new changes. Best regards, Ilya ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
