We can reproduce this issue by using the test_sockmap_with_close_on_write()

Current wrapper function create_pair() is used to create a pair of
connected links and returns two fds, but it does not support unix sockets.
Here we introduce socketpair() into create_pair(), which supports creating
a pair of unix sockets, since the semantics of the two are the same.

Hi Everyone,
This patch series fixes handling of module_kobject creation.
A driver expect module_kset list populated with its corresponding
module_kobject to create its /sys/module//drivers
directory.
Since,
[1] commit 96a1a2412acb ("kernel/params.c: defer most of param_sysfs_init() to
late_init
module_add_driver() relies on module_kset list for
/sys/module//drivers directory creation.
Since,
commit 96a1a2412acba ("kernel/params.c: defer most of param_sysfs_init() to
late_initcall time")
drivers which are initialized from subsys_initcall() or any other
higher precedence initcall couldn't
The locate_module_kobject() function looks up an existing
module_kobject for a given module name. If it cannot find the
corresponding module_kobject, it creates one for the given name.
This commit renames locate_module_kobject() to
lookup_or_create_module_kobject() to better describe its operation
In the unlikely event of the allocation failing, it is better to let
the machine boot with a not fully populated sysfs than to kill it with
this BUG_ON(). All callers are already prepared for
lookup_or_create_module_kobject() returning NULL.
This is also preparation for calling this function from

Welcome to v5. Patches 1, 2, and 4 have no functional changes only

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.

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 h

The `Index` implementation on `BStr` was lost when we switched `BStr` from
a type alias of `[u8]` to a newtype. Add back `Index` by implementing
`Index` for `BStr` when `Index` would be implemented for `[u8]`.

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
Extend the `module!` macro with support module parameters. Also add some string
to integer parsing functions and updates `BStr` with a method to strip a string
prefix.
Based on code by Adam Bratschi-Kaye lifted from the original `rust` branch [1].

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.
