Currently only the drivers that implement shaper or queue APIs
are grabbing instance lock. Add an explicit opt-in for the
drivers that want to grab the lock without implementing the above
APIs.

Lockdep reports possible circular dependency in [0]. Instead of
fixing the ordering, replace global dev_addr_sem with netdev
instance lock. Most of the paths that set/get mac are RTNL
protected. Two places where it's not, convert to explicit
locking:
- sysfs address_show
- dev_get_mac_address via dev_ioctl

Protect all ethtool callbacks and PHY related state with the netdev
instance lock, for drivers which want / need to have their ops
instance-locked. Basically take the lock everywhere we take rtnl_lock.
It was tempting to take the lock in ethnl_ops_begin(), but turns
out we actually nest those calls (when generating notifications).

To preserve the atomicity, hold the lock while applying multiple
attributes. The major issue with a full conversion to the instance
lock are software nesting devices (bonding/team/vrf/etc). Those
devices call into the core stack for their lower (potentially
real hw) devices. To avoid explicitly wrapping all those places
into instance lock/unlock, introduce new API boundaries:
- (some) existing dev_xxx calls are now considered "external"
(to drivers) APIs and they transparently grab the instance
lock if needed (dev_api.c)
- new netif_xxx calls are internal core stack API (naming is
sketchy, I've tried netdev_xxx_locked per Jakub's suggestion,
but it feels a bit verbose; but happy to get back to this
naming scheme if this is the preference)
This avoids touching most of the existing ioctl/sysfs/drivers paths.
Note the special handling of ndo_xxx_slave operations: I exploit
the fact that none of the drivers that call these functions
need/use instance lock. At the same time, they use dev_xxx
APIs, so the lower device has to be unlocked.
Changes in unregister_netdevice_many_notify (to protect dev->state
with instance lock) trigger lockdep - the loop over close_list
(mostly from cleanup_net) introduces spurious ordering issues.
netdev_lock_cmp_fn has a justification on why it's ok to suppress
for now.

For the drivers that use queue management API, switch to the mode where
core stack holds the netdev instance lock. This affects the following
drivers:
- bnxt
- gve
- netdevsim
Originally I locked only start/stop, but switched to holding the
lock over all iterations to make them look atomic to the device
(feels like it should be easier to reason about).

For the drivers that use shaper API, switch to the mode where
core stack holds the netdev lock. This affects two drivers:
* iavf - already grabs netdev lock in ndo_open/ndo_stop, so mostly
remove these
* netdevsim - switch to _locked APIs to avoid deadlock
iavf_close diff is a bit confusing, the existing call looks like this:
iavf_close() {
netdev_lock()
..
netdev_unlock()
wait_event_timeout(down_waitqueue)
}
I change it to the following:
netdev_lock()
iavf_close() {
..
netdev_unlock()
wait_event_timeout(down_waitqueue)
netdev_lock() // reusing this lock call
}
netdev_unlock()
Since I'm reusing existing netdev_lock call, so it looks like I only
add netdev_unlock.

Marcus Wichelmann says:
====================
XDP metadata support for tun driver
Hi all,
this v5 of the patch series is very similar to v4, but rebased onto the
bpf-next/net branch instead of bpf-next/master.
Because the commit c047e0e0e435 ("selftests/bpf: Optionally open a
dedicated namespace to run test in it") is not yet included in this branch,
I changed the xdp_context_tuntap test to manually create a namespace to run
the test in.
Not so successful pipeline: https://github.com/kernel-patches/bpf/actions/runs/13682405154
The CI pipeline failed because of veristat changes in seemingly unrelated
eBPF programs. I don't think this has to do with the changes from this
patch series, but if it does, please let me know what I may have to do
different to make the CI pass.

The open_tuntap helper function uses open() to get a file descriptor for
/dev/net/tun.
The open(2) manpage writes this about its return value:
On success, open(), openat(), and creat() return the new file
descriptor (a nonnegative integer). On error, -1 is returned and
errno is set to indicate the error.
This means that the fd > 0 assertion in the open_tuntap helper is
incorrect and should rather check for fd >= 0.
When running the BPF selftests locally, this incorrect assertion was not
an issue, but the BPF kernel-patches CI failed because of this:
open_tuntap:FAIL:open(/dev/net/tun) unexpected open(/dev/net/tun):
actual 0 <= expected 0

Add a selftest that creates a tap device, attaches XDP and TC programs,
writes a packet with a test payload into the tap device and checks the
test result. This test ensures that the XDP metadata support in the tun
driver is enabled and that the metadata size is correctly passed to the
skb.
See the previous commit ("selftests/bpf: refactor xdp_context_functional
test and bpf program") for details about the test design.
The test runs in its own network namespace. This provides some extra
safety against conflicting interface names.

The existing XDP metadata test works by creating a veth pair and
attaching XDP & TC programs that drop the packet when the condition of
the test isn't fulfilled. The test then pings through the veth pair and
succeeds when the ping comes through.
While this test works great for a veth pair, it is hard to replicate for
tap devices to test the XDP metadata support of them. A similar test for
the tun driver would either involve logic to reply to the ping request,
or would have to capture the packet to check if it was dropped or not.
To make the testing of other drivers easier while still maximizing code
reuse, this commit refactors the existing xdp_context_functional test to
use a test_result map. Instead of conditionally passing or dropping the
packet, the TC program is changed to copy the received metadata into the
value of that single-entry array map. Tests can then verify that the map
value matches the expectation.
This testing logic is easy to adapt to other network drivers as the only
remaining requirement is that there is some way to send a custom
Ethernet packet through it that triggers the XDP & TC programs.
The Ethernet header of that custom packet is all-zero, because it is not
required to be valid for the test to work. The zero ethertype also helps
to filter out packets that are not related to the test and would
otherwise interfere with it.
The payload of the Ethernet packet is used as the test data that is
expected to be passed as metadata from the XDP to the TC program and
written to the map. It has a fixed size of 32 bytes which is a
reasonable size that should be supported by both drivers. Additional
packet headers are not necessary for the test and were therefore skipped
to keep the testing code short.
This new testing methodology no longer requires the veth interfaces to
have IP addresses assigned, therefore these were removed.

To test the XDP metadata functionality of the tun driver, it's necessary
to create a new tap device first. A helper function for this already
exists in lwt_helpers.h. Move it to the common network helpers header,
so it can be reused in other tests.

When the XDP metadata area was used, it is expected that the same
metadata can also be accessed from TC, as can be read in the description
of the bpf_xdp_adjust_meta helper function. In the tun driver, this was
not yet implemented.
To make this work, the skb that is being built on XDP_PASS should know
of the current size of the metadata area. This is ensured by adding
calls to skb_metadata_set. For the tun_xdp_one code path, an additional
check is necessary to handle the case where the externally initialized
xdp_buff has no metadata support (xdp->data_meta == xdp->data + 1).
More information about this feature can be found in the commit message
of commit de8f3a83b0a0 ("bpf: add meta pointer for direct access").

Enable the support for the bpf_xdp_adjust_meta helper function for XDP
buffers initialized by the tun driver. This allows to reserve a metadata
area that is useful to pass any information from one XDP program to
another one, for example when using tail-calls.
Whether this helper function can be used in an XDP program depends on
how the xdp_buff was initialized. Most net drivers initialize the
xdp_buff in a way, that allows bpf_xdp_adjust_meta to be used. In case
of the tun driver, this is currently not the case.
There are two code paths in the tun driver that lead to a
bpf_prog_run_xdp and where metadata support should be enabled:
1. tun_build_skb, which is called by tun_get_user and is used when
writing packets from userspace into the device. In this case, the
xdp_buff created in tun_build_skb has no support for
bpf_xdp_adjust_meta and calls of that helper function result in
ENOTSUPP.
For this code path, it's sufficient to set the meta_valid argument of
the xdp_prepare_buff call. The reserved headroom is large enough
already.
2. tun_xdp_one, which is called by tun_sendmsg which again is called by
other drivers (e.g. vhost_net). When the TUN_MSG_PTR mode is used,
another driver may pass a batch of xdp_buffs to the tun driver. In
this case, that other driver is the one initializing the xdp_buff.
See commit 043d222f93ab ("tuntap: accept an array of XDP buffs
through sendmsg()") for details.
For now, the vhost_net driver is the only one using TUN_MSG_PTR and
it already initializes the xdp_buffs with metadata support and
sufficient headroom. But the tun driver disables it again, so the
xdp_set_data_meta_invalid call has to be removed.

This was another case that Rasmus pointed out where the direct access to
the pipe head and tail pointers broke on 32-bit configurations due to
the type changes.
As with the pipe FIONREAD case, fix it by using the appropriate helper
functions that deal with the right pipe index sizing.

Rasmus points out that we do indeed have other cases of breakage from
the type changes that were introduced on 32-bit targets in order to read
the pipe head and tail values atomically (commit 3d252160b818: "fs/pipe:
Read pipe->{head,tail} atomically outside pipe->mutex").
Fix it up by using the proper helper functions that now deal with the
pipe buffer index types properly. This makes the code simpler and more
obvious.
The compiler does the CSE and loop hoisting of the pipe ring size
masking that we used to do manually, so open-coding this was never a
good idea.

That's what 'pipe_full()' does, so it's more consistent. But more
importantly it gets the type limits right when the pipe head and tail
are no longer necessarily 'unsigned int'.

The call to flush_work before tearing down a table from the netlink
notifier was supposed to make sure that all earlier updates (e.g. rule
add) that might reference that table have been processed.
Unfortunately, flush_work() waits for the last queued instance.
This could be an instance that is different from the one that we must
wait for.
This is because transactions are protected with a pernet mutex, but the
work item is global, so holding the transaction mutex doesn't prevent
another netns from queueing more work.
Make the work item pernet so that flush_work() will wait for all
transactions queued from this netns.
A welcome side effect is that we no longer need to wait for transaction
objects from foreign netns.
The gc work queue is still global. This seems to be ok because nft_set
structures are reference counted and each container structure owns a
reference on the net namespace.
The destroy_list is still protected by a global spinlock rather than
pernet one but the hold time is very short anyway.
v2: call cancel_work_sync before reaping the remaining tables (Pablo).
Fixes: 9f6958ba2e90 ("netfilter: nf_tables: unconditionally flush pending work before notifier")

Since commit 5f73e7d0386d ("kbuild: refactor cross-compiling
linux-headers package"), the linux-headers pacman package fails
to build when "O=" is set. The build system complains:
/mnt/chroot/linux/scripts/Makefile.build:41: mnt/chroots/linux-mainline/pacman/linux-upstream/pkg/linux-upstream-headers/usr//lib/modules/6.14.0-rc3-00350-g771dba31fffc/build/scripts/Makefile: No such file or directory
This is because the "srcroot" variable is set to "." and the
"build" variable is set to the absolute path. This makes the
"src" variables point to wrong directory.
Change the "build" variable to a relative path to "." to
fix build.
