In the Linux kernel, the following vulnerability has been resolved:
bpf: Avoid splat in pskbpullreason
syzkaller builds (CONFIGDEBUGNET=y) frequently trigger a debug hint in pskbmaypull.
We'd like to retain this debug check because it might hint at integer overflows and other issues (kernel code should pull headers, not huge value).
In bpf case, this splat isn't interesting at all: such (nonsensical) bpf programs are typically generated by a fuzzer anyway.
Do what Eric suggested and suppress such warning.
For CONFIGDEBUGNET=n we don't need the extra check because pskbmaypull will do the right thing: return an error without the WARN() backtrace.
