selftests/bpf: Fix flaky cgroup_iter_sleepable subtest

Occasionally, with './test_progs -j' on my vm, I will hit the
following failure:

test_cgrp_local_storage:PASS:join_cgroup /cgrp_local_storage 0 nsec
test_cgroup_iter_sleepable:PASS:skel_open 0 nsec
test_cgroup_iter_sleepable:PASS:skel_load 0 nsec
test_cgroup_iter_sleepable:PASS:attach_iter 0 nsec

test_cgroup_iter_sleepable:FAIL:cgroup_id unexpected cgroup_id: actual 1 != expected 2812
#48/5 cgrp_local_storage/cgroup_iter_sleepable:FAIL
#48 cgrp_local_storage:FAIL

Finally, I decided to do some investigation since the test is introduced
by myself. It turns out the reason is due to cgroup_fd with value 0.
In cgroup_iter, a cgroup_fd of value 0 means the root cgroup.

/* from cgroup_iter.c */
if (fd)
cgrp = cgroup_v1v2_get_from_fd(fd);
else if (id)
cgrp = cgroup_get_from_id(id);
else /* walk the entire hierarchy by default. */
cgrp = cgroup_get_from_path("/");

That is why we got cgroup_id 1 instead of expected 2812.

Why we got a cgroup_fd 0? Nobody should really touch 'stdin' (fd 0) in
test_progs. I traced 'close' syscall with stack trace and found the root
cause, which is a bug in bpf_obj_pinning.c. Basically, the code closed
fd 0 although it should not. Fixing the bug in bpf_obj_pinning.c also
resolved the above cgroup_iter_sleepable subtest failure.

Merge tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking changes from Jakub Kicinski:
"WiFi 7 and sendpage changes are the biggest pieces of work for this
release. The latter will definitely require fixes but I think that we
got it to a reasonable point.

Core:

- Rework the sendpage & splice implementations

Instead of feeding data into sockets page by page extend sendmsg
handlers to support taking a reference on the data, controlled by a
new flag called MSG_SPLICE_PAGES

Rework the handling of unexpected-end-of-file to invoke an
additional callback instead of trying to predict what the right
combination of MORE/NOTLAST flags is

Remove the MSG_SENDPAGE_NOTLAST flag completely

- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid

- Enable socket busy polling with CONFIG_RT

- Improve reliability and efficiency of reporting for ref_tracker

- Auto-generate a user space C library for various Netlink families

Protocols:

- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2]

- Use per-VMA locking for "page-flipping" TCP receive zerocopy

- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags

- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative

- Create a new MPTCP getsockopt to retrieve all info
(MPTCP_FULL_INFO)

- Avoid waking up applications using TLS sockets until we have a full
record

- Allow using kernel memory for protocol ioctl callbacks, paving the
way to issuing ioctls over io_uring

- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address

- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch

- PPPoE: make number of hash bits configurable

- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig)

- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge)

- Support matching on Connectivity Fault Management (CFM) packets

- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug

- HSR: don't enable promiscuous mode if device offloads the proto

- Support active scanning in IEEE 802.15.4

- Continue work on Multi-Link Operation for WiFi 7

BPF:

- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used, or
in fact passing the verifier at all for complex programs,
especially those using open-coded iterators

- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what the
output buffer *should* be, without writing anything

- Accept dynptr memory as memory arguments passed to helpers

- Add routing table ID to bpf_fib_lookup BPF helper

- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands

- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only)

- Show target_{obj,btf}_id in tracing link fdinfo

- Addition of several new kfuncs (most of the names are
self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs

Netfilter:

- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value

- Increase ip_vs_conn_tab_bits range for 64BIT builds

- Allow updating size of a set

- Improve NAT tuple selection when connection is closing

Driver API:

- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out)

- Support configuring rate selection pins of SFP modules

- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines

- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer

- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio)

- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message

- Split devlink instance and devlink port operations

selftests/bpf: Add path_fd-based BPF_OBJ_PIN and BPF_OBJ_GET tests

Add a selftest demonstrating using detach-mounted BPF FS using new mount
APIs, and pinning and getting BPF map using such mount. This
demonstrates how something like container manager could setup BPF FS,
pin and adjust all the necessary objects in it, all before exposing BPF
FS to a particular mount namespace.

Also add a few subtests validating all meaningful combinations of
path_fd and pathname. We use mounted /sys/fs/bpf location for these.
