2025-02-14	selftests/bpf: Add selftest for may_goto	Jiayuan Chen
	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 ...

2023-12-02	bpf: simplify tnum output if a fully known constant	Andrii Nakryiko
	Emit tnum representation as just a constant if all bits are known. Use decimal-vs-hex logic to determine exact format of emitted constant value, just like it's done for register range values. For that move tnum_strn() to kernel/bpf/log.c to reuse decimal-vs-hex determination logic and constants.
