Commitef01f4e25c("bpf: restore the ebpf program ID for BPF_AUDIT_UNLOAD and PERF_BPF_EVENT_PROG_UNLOAD") stopped removing program's id from idr when the offloaded/bound netdev goes away. I was supposed to take a look and check in [0], but apparently I did not. Martin points out it might be useful to keep it that way for observability sake, but we at least need to mark those programs as unusable. Mark those programs as 'orphaned' and keep printing the list when we encounter ENODEV. 0: unspec tag 0000000000000000 xlated 0B not jited memlock 4096B orphaned [0]: https://lore.kernel.org/all/CAKH8qBtyR20ZWAc11z1-6pGb3Hd47AQUTbE_cfoktG59TqaJ7Q@mail.gmail.com/ v3: * use two spaces for " orphaned" (Quentin) Cc: netdev@vger.kernel.org Fixes:ef01f4e25c("bpf: restore the ebpf program ID for BPF_AUDIT_UNLOAD and PERF_BPF_EVENT_PROG_UNLOAD") Signed-off-by: Stanislav Fomichev <sdf@google.com> Reviewed-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/r/20231127182057.1081138-1-sdf@google.com Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org>
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.
