x86: warning: kernel stack regs has bad 'bp' value

[Andrey Konovalov]

Hi,

I've got the following error report while fuzzing the kernel with syzkaller.

On commit 89c9fea3c8034cdb2fd745f551cde0b507fd6893 (4.11.0+).

A reproducer and .config are attached.

The reproducer open SCTP sockets and sends data to it in a loop.
I'm not sure whether this is an issue with SCTP or with something else.
