May I ask in what case
consider C program represented in eBPF:
int filter(int arg)
{
int a, b, c, *ptr;
if (arg == 1)
ptr =
else if (arg == 2)
ptr =
else
ptr =
*ptr = 0;
return 0;
}
eBPF verifier has to follow all possible paths through the program
to recognize that
add 4 extra tests to cover jump verification better

Hi All,
patch #1 commit log explains why eBPF verifier has to examine some
instructions multiple times and describes the search pruning optimization
that improves verification speed for branchy programs and allows more
complex programs to be verified successfully.
This patch completes the core
Constify dump_page so that we could dump_page const pages, there is no
functional change here.

Currently we're seeing a few issues which are unexplainable by looking at the
data we see and are most likely caused by a memory corruption caused
elsewhere.
This is wasting time for folks who are trying to figure out an issue provided
a stack trace that can't really point out the real issue.
