Alexei Starovoitov 548f1191d8 bpf: Unbreak BPF_PROG_TYPE_KPROBE when kprobe is called via do_int3 The commit `0d00449c7a` ("x86: Replace ist_enter() with nmi_enter()") converted do_int3 handler to be "NMI-like". That made old if (in_nmi()) check abort execution of bpf programs attached to kprobe when kprobe is firing via int3 (For example when kprobe is placed in the middle of the function). Remove the check to restore user visible behavior.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
