Allow resilient nexthop groups to be programmed and account their occupancy according to their number of buckets. The nexthop group itself as well as its buckets are marked with hardware flags (i.e., 'RTNH_F_TRAP'). Replacement of a single nexthop bucket can fail using the following debugfs knob: # cat /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_nexthop_bucket_replace N # echo 1 > /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_nexthop_bucket_replace # cat /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_nexthop_bucket_replace Y Replacement of a resilient nexthop group can fail using the following debugfs knob: # cat /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_res_nexthop_group_replace N # echo 1 > /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_res_nexthop_group_replace # cat /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_res_nexthop_group_replace Y This enables testing of various error paths.

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.
