hi,
might be some fail on my side, but I had to include bpf_experimental.h to
compile this.. ci seems ok
CLNG-BPF [test_progs-cpuv4] verifier_private_stack.bpf.o
progs/verifier_private_stack.c:174:2: error: call to undeclared function 'bpf_throw'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
174 | bpf_throw(0);
Yeah. Let's add bpf_experimental.h for folks like Jiri
who didn't upgrade their pahole for a long time :)
bpf_throw will be in vmlinux.h ;)
Okay, will do.
