Hi, I'm using the `bpf_asm` tool to do some syscall filtering, and found out the hard way that its error checking isn't very strict. In particular, it issues a warning (not an error) when a jump offset overflows the instruction's field. It really seems like this *ought* to be a hard error, but I see from the commit message in 7e22077d0c73a68ff3fd8b3d2f6564fcbcf8cb23 that this was left as a warning due to backwards compatibility concerns. I'm skeptical of this trade-off, but would people at least be open to adding a -Werror flag or the like, if changing it to a hard error unconditionally is off the table? Relatedly, while looking through the code I noticed there are several places where an error occurs that does cause to tool to exit without generating code, but it exits with 0 (success) status code. It seems like this ought to report a failure to the caller? -Ian
