Added test cases to ensure that programs with stack sizes exceeding 512 bytes are restricted in non-JITed mode, and can be executed normally in JITed mode, even with stack sizes exceeding 512 bytes due to the presence of may_goto instructions. Test result: echo "0" > /proc/sys/net/core/bpf_jit_enable ./test_progs -t verifier_stack_ptr ... stack size 512 with may_goto with jit:SKIP stack size 512 with may_goto without jit:OK ... Summary: 1/27 PASSED, 25 SKIPPED, 0 FAILED echo "1" > /proc/sys/net/core/bpf_jit_enable ./test_progs -t verifier_stack_ptr ... stack size 512 with may_goto with jit:OK stack size 512 with may_goto without jit:SKIP ... Summary: 1/27 PASSED, 25 SKIPPED, 0 FAILED Signed-off-by: Jiayuan Chen <mrpre@163.com> Link: https://lore.kernel.org/r/20250214091823.46042-4-mrpre@163.com 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 reStructuredText 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.
