Generic XDP and driver XDP cannot be enabled at the same time. However,
they don't share any state; let's fix that. Here, dev->xdp_prog, is
used for both driver and generic mode. This removes the need for the
XDP_QUERY_PROG command to ndo_bpf.

Hmm, please correct me if I'm wrong, but from reading this patch (with following
generic XDP as a simple example), it means: above we inc ref on prog, fetch old
prog, assign new prog to dev->xdp_prog, call generic_xdp_install(). If one would
fail there, we drop the ref of the prog that is currently attached to dev->xdp_prog
(effectively a use-after-free?), and assign the old prog back. So basically we
would shortly flake wrt prog assignment. I don't think this is a good design, the
update should only really happen once everything else succeeded and there is nothing
that can fail anymore. The existing code is doing exactly the latter, why diverge
from this practice?! (Also, why special casing XDP_FLAGS_HW_MODE? Feels a bit like
a hack tbh.)

Really late reply. :-(
Yeah, I need to rework this one. My loose plan was to add the XDP
program to the netdevice (skb/native being mutual exclusive), and
later the per-queue program into the netdev_rx_queue structure. I left
HW programs out, keeping the old query mechanism. It probably makes
sense to add the offloaded program to the netdevice (and later to the
netdev_rx_queue) as well. IOW, two XDP-programs: skb/native and
offloaded in the netdev structure.
The update flow was: 1. update the netdev structures, and 2. call the
ndo (if applicable). 3. revert if fail.
I'll update this patch to follow the existing pattern: 1. try changing
the program via the ndos (if applicable) 2. update the netdevice on
success.

An XDP program can redirect packets between interfaces using either the
xdp_redirect() helper or the xdp_redirect_map() helper. Apart from the
flexibility of updating maps from userspace, the redirect_map() helper also
uses the map structure to batch packets, which results in a significant
(around 50%) performance boost. However, the xdp_redirect() API is simpler
if one just wants to redirect to another interface, which means people tend
to use this interface and then wonder why they getter worse performance
than expected.
This patch seeks to close this performance difference between the two APIs.
It achieves this by changing xdp_redirect() to use a hidden devmap for
looking up destination interfaces, thus gaining the batching benefit with
no visible difference from the user API point of view.
A hidden per-namespace map is allocated when an XDP program that uses the
non-map xdp_redirect() helper is first loaded. This map is populated with
all available interfaces in its namespace, and kept up to date as
interfaces come and go. Once allocated, the map is kept around until the
namespace is removed.
The hidden map uses the ifindex as map key, which means they are limited to
ifindexes smaller than the map size of 64. A later patch introduces a new
map type to lift this restriction.
Performance numbers:
Before patch:
xdp_redirect: 5426035 pkt/s
xdp_redirect_map: 8412754 pkt/s
After patch:
xdp_redirect: 8314702 pkt/s
xdp_redirect_map: 8411854 pkt/s
This corresponds to a 53% increase in xdp_redirect performance, or a
reduction in per-packet processing time by 64 nanoseconds.

A common pattern when using xdp_redirect_map() is to create a device map
where the lookup key is simply ifindex. Because device maps are arrays,
this leaves holes in the map, and the map has to be sized to fit the
largest ifindex, regardless of how many devices actually are actually
needed in the map.
This patch adds a second type of device map where the key is interpreted as
an ifindex and looked up using a hashmap, instead of being used as an array
index. This leads to maps being densely packed, so they can be smaller.
The default maps used by xdp_redirect() are changed to use the new map
type, which means that xdp_redirect() is no longer limited to ifindex < 64,
but instead to 64 total simultaneous interfaces per network namespace. This
also provides an easy way to compare the performance of devmap and
devmap_idx:
xdp_redirect_map (devmap): 8394560 pkt/s
xdp_redirect (devmap_idx): 8179480 pkt/s
Difference: 215080 pkt/s or 3.1 nanoseconds per packet.

The subsequent commits introducing default maps and a hash-based ifindex
devmap require a bit of refactoring of the devmap code. Perform this first
so the subsequent commits become easier to read.
Also split out the final freeing and flushing of devmaps into a workqueue,
to make it easier to queue up the freeing of maps in the subsequent
patches.
Finally, change the spin lock into a mutex, as subsequent patches add code
that needs to be able to sleep while holding the lock.

With the previous patch, we no longer need the XDP_QUERY_PROG operation, so
remove the handling of that from all drivers.

This adds a new selftest checking the allocation and de-allocation of
default maps in different network namespaces. It loads the two different
kinds of programs that need allocation (programs using tail calls, and
programs using redirect), and moves interfaces around between namespaces to
make sure the default map is correctly allocated and de-allocated in each
of the namespaces.
