git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux fix from Paul Moore:
"A relatively small SELinux patch to fix an issue with a
vfs/LSM/SELinux patch that went upstream during the recent merge
window.
The short version is that the original patch changed how we
initialized mount options to resolve a NFS issue and we inadvertently
broke a use case due to the changed behavior.
The fix restores this behavior for the cases that require it while
keeping the original NFS fix in place"

Marcus and Satya reported an issue where BTF_ID macro generates same
symbol in separate objects and that breaks final vmlinux link.
ld.lld: error: ld-temp.o <inline asm>:14577:1: symbol
'__BTF_ID__struct__cgroup__624' is already defined
This can be triggered under specific configs when __COUNTER__ happens to
be the same for the same symbol in two different translation units,
which is already quite unlikely to happen.
Add __LINE__ number suffix to make BTF_ID symbol more unique, which is
not a complete fix, but it would help for now and meanwhile we can work
on better solution as suggested by Andrii.

There is no fundamental reason, why multi-buffer XDP and XDP kfunc RX hints
cannot coexist in a single program.
Allow those features to be used together by modifying the flags condition
for dev-bound-only programs, segments are still prohibited for fully
offloaded programs, hence additional check.

Stanislav Fomichev says:
====================
Extend netdev netlink family to expose the bitmask with the
kfuncs that the device implements. The source of truth is the
device's xdp_metadata_ops. There is some amount of auto-generated
netlink boilerplate; the change itself is super minimal.

- print "xdp-features" and "xdp-rx-metadata-features" so it's clear

Add new xdp-rx-metadata-features member to netdev netlink
which exports a bitmask of supported kfuncs. Most of the patch
is autogenerated (headers), the only relevant part is netdev.yaml
and the changes in netdev-genl.c to marshal into netlink.
Example output on veth:
$ ip link add veth0 type veth peer name veth1 # ifndex == 12
$ ./tools/net/ynl/samples/netdev 12
Select ifc ($ifindex; or 0 = dump; or -2 ntf check): 12
veth1[12] xdp-features (23): basic redirect rx-sg xdp-rx-metadata-features (3): timestamp hash xdp-zc-max-segs=0

No functional changes.
Instead of having hand-crafted code in bpf_dev_bound_resolve_kfunc,
move kfunc <> xmo handler relationship into XDP_METADATA_KFUNC_xxx.
This way, any time new kfunc is added, we don't have to touch
bpf_dev_bound_resolve_kfunc.
Also document XDP_METADATA_KFUNC_xxx arguments since we now have
more than two and it might be confusing what is what.

Userspace applications indicate their multi-buffer capability to xsk
using XSK_USE_SG socket bind flag. For sockets using shared umem the
bind flag may contain XSK_USE_SG only for the first socket. For any
subsequent socket the only option supported is XDP_SHARED_UMEM.
Add option XDP_UMEM_SG_FLAG in umem config flags to store the
multi-buffer handling capability when indicated by XSK_USE_SG option in
bing flag by the first socket. Use this to derive multi-buffer capability
for subsequent sockets in xsk core.

bpf_nf testcase fails on s390x: bpf_skb_ct_lookup() cannot find the entry
that was added by bpf_ct_insert_entry() within the same BPF function.
The reason is that this entry is deleted by nf_ct_gc_expired().
The CT timeout starts ticking after the CT confirmation; therefore
nf_conn.timeout is initially set to the timeout value, and
__nf_conntrack_confirm() sets it to the deadline value.
bpf_ct_insert_entry() sets IPS_CONFIRMED_BIT, but does not adjust the
timeout, making its value meaningless and causing false positives.
Fix the problem by making bpf_ct_insert_entry() adjust the timeout,
like __nf_conntrack_confirm().

If port VLAN is configured on a VF then any other VLANs on top of this VF
are broken.
During i40e_ndo_set_vf_port_vlan() call the i40e driver reset the VF and
iavf driver asks PF (using VIRTCHNL_OP_GET_VF_RESOURCES) for VF capabilities
but this reset occurs too early, prior setting of vf->info.pvid field
and because this field can be zero during i40e_vc_get_vf_resources_msg()
then VIRTCHNL_VF_OFFLOAD_VLAN capability is reported to iavf driver.
This is wrong because iavf driver should not report VLAN offloading
capability when port VLAN is configured as i40e does not support QinQ
offloading.
Fix the issue by moving VF reset after setting of vf->port_vlan_id
field.

When the iavf driver wants to reconfigure the VLAN filters
(iavf_add_vlan, iavf_del_vlan), it sets a flag in
aq_required:
adapter->aq_required |= IAVF_FLAG_AQ_ADD_VLAN_FILTER;
or:
adapter->aq_required |= IAVF_FLAG_AQ_DEL_VLAN_FILTER;
This is later processed by the watchdog_task, but it runs periodically
every 2 seconds, so it can be a long time before it processes the request.
In the worst case, the interface is unable to receive traffic for more
than 2 seconds for no objective reason.

Currently, if the OPEN compound experiencing an error and needs to
get the file attributes separately, it will send a stand alone
GETATTR but it would use the filehandle from the results of
the OPEN compound. In case of the CLAIM_FH OPEN, nfs_openres's fh
is zero value. That generate a GETATTR that's sent with a zero
value filehandle, and results in the server returning an error.
Instead, for the CLAIM_FH OPEN, take the filehandle that was used
in the PUTFH of the OPEN compound.

netfilter pull request 23-09-13
====================
The following patchset contains Netfilter fixes for net:
1) Do not permit to remove rules from chain binding, otherwise
double rule release is possible, triggering UaF. This rule
deletion support does not make sense and userspace does not use
this. Problem exists since the introduction of chain binding support.
2) rbtree GC worker only collects the elements that have expired.
This operation is not destructive, therefore, turn write into
read spinlock to avoid datapath contention due to GC worker run.
This was not fixed in the recent GC fix batch in the 6.5 cycle.
3) pipapo set backend performs sync GC, therefore, catchall elements
must use sync GC queue variant. This bug was introduced in the
6.5 cycle with the recent GC fixes.
4) Stop GC run if memory allocation fails in pipapo set backend,
otherwise access to NULL pointer to GC transaction object might
occur. This bug was introduced in the 6.5 cycle with the recent
GC fixes.
5) rhash GC run uses an iterator that might hit EAGAIN to rewind,
triggering double-collection of the same element. This bug was
introduced in the 6.5 cycle with the recent GC fixes.
6) Do not permit to remove elements in anonymous sets, this type of
sets are populated once and then bound to rules. This fix is
similar to the chain binding patch coming first in this batch.
API permits since the very beginning but it has no use case from
userspace.

net: Add Half Duplex support for ICSSG Driver
This series adds support for half duplex operation for ICSSG driver.
In order to support half-duplex operation at 10M and 100M link speeds, the
PHY collision detection signal (COL) should be routed to ICSSG GPIO pin
(PRGx_PRU0/1_GPI10) so that firmware can detect collision signal and apply
the CSMA/CD algorithm applicable for half duplex operation. A DT property,
"ti,half-duplex-capable" is introduced for this purpose in the first patch
of the series. If board has PHY COL pin conencted to PRGx_PRU1_GPIO10,
this DT property can be added to eth node of ICSSG, MII port to support
half duplex operation at that port.
Second patch of the series configures driver to support half-duplex
operation if the DT property "ti,half-duplex-capable" is enabled.
This series addresses comments on [v2]. This series is based on the latest
net-next/main. This series has no dependency.
Changes from v1 to v2:
*) Changed the description of "ti,half-duplex-capable" property as asked
by Rob and Andrew to avoid confusion between capable and enable.
Changes from v1 to v2:
*) Dropped the RFC tag.
*) Added RB tags of Andrew and Roger.

This patch adds support for half duplex operation at 10M and 100M link
speeds for AM654x/AM64x devices.
- Driver configures rand_seed, a random number, in DMEM HD_RAND_SEED_OFFSET
field, which will be used by firmware for Back off time calculation.
- Driver informs FW about half duplex link operation in DMEM
PORT_LINK_SPEED_OFFSET field by setting bit 7 for 10/100M HD.
Hence, the half duplex operation depends on board design the
"ti,half-duplex-capable" property has to be enabled for ICSS-G ports if HW
is capable to perform half duplex.

Alex reported that running ssh over IPv6 does not work with
Thunderbolt/USB4 networking driver. The reason for that is that driver
should call skb_is_gso() before calling skb_is_gso_v6(), and it should
not return false after calculates the checksum successfully. This probably
was a copy paste error from the original driver where it was done properly.

add_control_with_pfx() constructs a mixer name element with the fixed
size, and it got compile warnings with -Wformat-truncation.
Although the size overflow is very unlikely, let's have a sanity check
of the string size and returns the error if it really doesn't fit
instead of silent truncation.

Alex reported that after rebooting the other host the peer-to-peer link
does not come up anymore. The reason for this is that the host that was
not rebooted tries to send the UUID request only 10 times according to
the USB4 Inter-Domain spec and gives up if it does not get reply. Then
when the other side is actually ready it cannot get the link established
anymore. The USB4 Inter-Domain spec requires that the discovery protocol
is restarted in that case so implement this now.
