This reverts commit
5e85eba6f50dc288c22083a7e213152bcc4b8208.
Thomas Witt reported that
5e85eba6f50d ("PCI/ASPM: Refactor L1 PM Substates
Control Register programming") broke suspend/resume on a Tuxedo
Infinitybook S 14 v5, which seems to use a Clevo L140CU Mainboard.
The main symptom is:
iwlwifi 0000:02:00.0: Unable to change power state from D3hot to D0, device inaccessible
nvme 0000:03:00.0: Unable to change power state from D3hot to D0, device inaccessible
and the machine is only partially usable after resume. It can't run dmesg
and can't do a clean reboot. This happens on every suspend/resume cycle.
Revert
5e85eba6f50d until we can figure out the root cause.

Revert "PCI/ASPM: Save L1 PM Substates Capability for suspend/resume"
This reverts commit
4ff116d0d5fd8a025604b0802d93a2d5f4e465d1.
Tasev Nikola and Mark Enriquez reported that resume from suspend was broken
in v6.1-rc1. Tasev bisected to
a47126ec29f5 ("PCI/PTM: Cache PTM
Capability offset"), but we can't figure out how that could be related.
Mark saw the same symptoms and bisected to
4ff116d0d5fd ("PCI/ASPM: Save L1
PM Substates Capability for suspend/resume"), which does have a connection:
it restores L1 Substates configuration while ASPM L1 may be enabled:
pci_restore_state
pci_restore_aspm_l1ss_state
aspm_program_l1ss
pci_write_config_dword(PCI_L1SS_CTL1, ctl1) # L1SS restore
pci_restore_pcie_state
pcie_capability_write_word(PCI_EXP_LNKCTL, cap[i++]) # L1 restore
which is a problem because PCIe r6.0, sec 5.5.4, requires that:
If setting either or both of the enable bits for ASPM L1 PM
Substates, both ports must be configured as described in this
section while ASPM L1 is disabled.
Separately, Thomas Witt reported that
5e85eba6f50d ("PCI/ASPM: Refactor L1
PM Substates Control Register programming") broke suspend/resume, and it
depends on
4ff116d0d5fd.
Revert
4ff116d0d5fd ("PCI/ASPM: Save L1 PM Substates Capability for
suspend/resume") to fix the resume issue and enable revert of
5e85eba6f50d
to fix the issue Thomas reported.
Note that reverting
4ff116d0d5fd means L1 Substates config may be lost on
suspend/resume. As far as we know the system will use more power but will
still *work* correctly.

The PGID_MCIPV6 is configured correctly to not flood to the CPU,

Furthermore, when I disable back PTP RX timestamping (ptp4l doesn't do
that when it exists), packets are RX filtered again as they should be:

So it's clear that something in the PTP RX trapping logic went wrong.
Looking a bit at the code, I can see that there are 4 typos, which
populate "ipv4" VCAP IS2 key filter fields for IPv6 keys.
VCAP IS2 keys of type OCELOT_VCAP_KEY_IPV4 and OCELOT_VCAP_KEY_IPV6 are
handled by is2_entry_set(). OCELOT_VCAP_KEY_IPV4 looks at
&filter->key.ipv4, and OCELOT_VCAP_KEY_IPV6 at &filter->key.ipv6.
Simply put, when we populate the wrong key field, &filter->key.ipv6
fields "proto.mask" and "proto.value" remain all zeroes (or "don't care").
So is2_entry_set() will enter the "else" of this "if" condition:
if (msk == 0xff && (val == IPPROTO_TCP || val == IPPROTO_UDP))
and proceed to ignore the "proto" field. The resulting rule will match
on all IPv6 traffic, trapping it to the CPU.
This is the reason why the local_termination.sh selftest sees it,
because control traps are stronger than the PGID_MCIPV6 used for
flooding (from the forwarding data path).
But the problem is in fact much deeper. We trap all IPv6 traffic to the
CPU, but if we're bridged, we set skb->offload_fwd_mark = 1, so software
forwarding will not take place and IPv6 traffic will never reach its
destination.
The fix is simple - correct the typos.
I was intentionally inaccurate in the commit message about the breakage
occurring when any PTP timestamping is enabled. In fact it only happens
when L4 timestamping is requested (HWTSTAMP_FILTER_PTP_V2_EVENT or
HWTSTAMP_FILTER_PTP_V2_L4_EVENT). But ptp4l requests a larger RX
timestamping filter than it needs for "-2": HWTSTAMP_FILTER_PTP_V2_EVENT.
I wanted people skimming through git logs to not think that the bug
doesn't affect them because they only use ptp4l in L2 mode.

drm/amdgpu/fence: Fix oops due to non-matching drm_sched init/fini
Currently amdgpu calls drm_sched_fini() from the fence driver sw fini
routine - such function is expected to be called only after the
respective init function - drm_sched_init() - was executed successfully.
Happens that we faced a driver probe failure in the Steam Deck
recently, and the function drm_sched_fini() was called even without
its counter-part had been previously called, causing the following oops:

To prevent that, check if the drm_sched was properly initialized for a
given ring before calling its fini counter-part.
Notice ideally we'd use sched.ready for that; such field is set as the latest
thing on drm_sched_init(). But amdgpu seems to "override" the meaning of such
field - in the above oops for example, it was a GFX ring causing the crash, and
the sched.ready field was set to true in the ring init routine, regardless of
the state of the DRM scheduler. Hence, we ended-up using sched.ops as per
Christian's suggestion [0], and also removed the no_scheduler check [1].

mptcp: be careful on subflow status propagation on errors
Currently the subflow error report callback unconditionally
propagates the fallback subflow status to the owning msk.
If the msk is already orphaned, the above prevents the code
from correctly tracking the msk moving to the TCP_CLOSE state
and doing the appropriate cleanup.
All the above causes increasing memory usage over time and
sporadic self-tests failures.
There is a great deal of infrastructure trying to propagate
correctly the fallback subflow status to the owning mptcp socket,
e.g. via mptcp_subflow_eof() and subflow_sched_work_if_closed():

net: ethernet: mtk_eth_soc: fix DSA TX tag hwaccel for switch port 0
Arınç reports that on his MT7621AT Unielec U7621-06 board and MT7623NI
Bananapi BPI-R2, packets received by the CPU over mt7530 switch port 0
(of which this driver acts as the DSA master) are not processed
correctly by software. More precisely, they arrive without a DSA tag
(in packet or in the hwaccel area - skb_metadata_dst()), so DSA cannot
demux them towards the switch's interface for port 0. Traffic from other
ports receives a skb_metadata_dst() with the correct port and is demuxed
properly.
Looking at mtk_poll_rx(), it becomes apparent that this driver uses the
skb vlan hwaccel area:
union {
u32 vlan_all;
struct {
__be16 vlan_proto;
__u16 vlan_tci;
};
};
as a temporary storage for the VLAN hwaccel tag, or the DSA hwaccel tag.
If this is a DSA master it's a DSA hwaccel tag, and finally clears up
the skb VLAN hwaccel header.
I'm guessing that the problem is the (mis)use of API.
skb_vlan_tag_present() looks like this:
#define skb_vlan_tag_present(__skb) (!!(__skb)->vlan_all)
So if both vlan_proto and vlan_tci are zeroes, skb_vlan_tag_present()
returns precisely false. I don't know for sure what is the format of the
DSA hwaccel tag, but I surely know that lowermost 3 bits of vlan_proto
are 0 when receiving from port 0:
unsigned int port = vlan_proto & GENMASK(2, 0);
If the RX descriptor has no other bits set to non-zero values in
RX_DMA_VTAG, then the call to __vlan_hwaccel_put_tag() will not, in
fact, make the subsequent skb_vlan_tag_present() return true, because
it's implemented like this:
static inline void __vlan_hwaccel_put_tag(struct sk_buff *skb,
__be16 vlan_proto, u16 vlan_tci)
{
skb->vlan_proto = vlan_proto;
skb->vlan_tci = vlan_tci;
}
What we need to do to fix this problem (assuming this is the problem) is
to stop using skb->vlan_all as temporary storage for driver affairs, and
just create some local variables that serve the same purpose, but
hopefully better. Instead of calling skb_vlan_tag_present(), let's look
at a boolean has_hwaccel_tag which we set to true when the RX DMA
descriptors have something. Disambiguate based on netdev_uses_dsa()
whether this is a VLAN or DSA hwaccel tag, and only call
__vlan_hwaccel_put_tag() if we're certain it's a VLAN tag.
Arınç confirms that the treatment works, so this validates the
assumption.

net: mana: Fix accessing freed irq affinity_hint
After calling irq_set_affinity_and_hint(), the cpumask pointer is
saved in desc->affinity_hint, and will be used later when reading

persistent. Otherwise, we are accessing freed memory when reading
the affinity_hint file.
Also, need to clear affinity_hint before free_irq(), otherwise there
is a one-time warning and stack trace during module unloading:

net/mlx5e: Update rx ring hw mtu upon each rx-fcs flag change
rq->hw_mtu is used in function en_rx.c/mlx5e_skb_from_cqe_mpwrq_linear()

packet then the check should be updated accordingly.
Rx rings initialization (mlx5e_init_rxq_rq()) invoked for every new set
of channels, as part of mlx5e_safe_switch_params(), unknowingly if it
runs with default configuration or not. Current rq->hw_mtu
initialization assumes default configuration and ignores

Fix this, by accounting for params->scatter_fcs_en flag state during

In addition, updating rq->hw_mtu value during ingress traffic might
lead to packets drop and oversize_pkts_sw_drop counter increase with no
good reason. Hence we remove this optimization and switch the set of

d) No CF shall begin, or resume, transmission on the network until 250
ms after it has successfully claimed an address except when
responding to a request for address-claimed.
But "Figure 6" and "Figure 7" in "4.5.4.2 - Address-claim
prioritization" show that the CF begins the transmission after 250 ms
from the first AC (address-claimed) message even if it sends another AC
message during that time window to resolve the address contention with
another CF.
As stated in "4.4.2.3 - Address-claimed message":
In order to successfully claim an address, the CF sending an address
claimed message shall not receive a contending claim from another CF
for at least 250 ms.
As stated in "4.4.3.2 - NAME management (NM) message":
1) A commanding CF can
d) request that a CF with a specified NAME transmit the address-
claimed message with its current NAME.
2) A target CF shall
d) send an address-claimed message in response to a request for a

Taking the above arguments into account, the 250 ms wait is requested
only during network initialization.
Do not restart the timer on AC message if both the NAME and the address
match and so if the address has already been claimed (timer has expired)
or the AC message has been sent to resolve the contention with another

net: mscc: ocelot: fix VCAP filters not matching on MAC with "protocol 802.1Q"
Alternative short title: don't instruct the hardware to match on
EtherType with "protocol 802.1Q" flower filters. It doesn't work for the
reasons detailed below.
With a command such as the following:
tc filter add dev $swp1 ingress chain $(IS1 2) pref 3 \
protocol 802.1Q flower skip_sw vlan_id 200 src_mac $h1_mac \
action vlan modify id 300 \
action goto chain $(IS2 0 0)
the created filter is set by ocelot_flower_parse_key() to be of type
OCELOT_VCAP_KEY_ETYPE, and etype is set to {value=0x8100, mask=0xffff}.
This gets propagated all the way to is1_entry_set() which commits it to
hardware (the VCAP_IS1_HK_ETYPE field of the key). Compare this to the
case where src_mac isn't specified - the key type is OCELOT_VCAP_KEY_ANY,
and is1_entry_set() doesn't populate VCAP_IS1_HK_ETYPE.
The problem is that for VLAN-tagged frames, the hardware interprets the
ETYPE field as holding the encapsulated VLAN protocol. So the above
filter will only match those packets which have an encapsulated protocol
of 0x8100, rather than all packets with VLAN ID 200 and the given src_mac.
The reason why this is allowed to occur is because, although we have a
block of code in ocelot_flower_parse_key() which sets "match_protocol"
to false when VLAN keys are present, that code executes too late.
There is another block of code, which executes for Ethernet addresses,
and has a "goto finished_key_parsing" and skips the VLAN header parsing.
By skipping it, "match_protocol" remains with the value it was
initialized with, i.e. "true", and "proto" is set to f->common.protocol,
or 0x8100.
The concept of ignoring some keys rather than erroring out when they are
present but can't be offloaded is dubious in itself, but is present
since the initial commit
fe3490e6107e ("net: mscc: ocelot: Hardware
ofload for tc flower filter"), and it's outside of the scope of this
patch to change that.
The problem was introduced when the driver started to interpret the
flower filter's protocol, and populate the VCAP filter's ETYPE field
based on it.
To fix this, it is sufficient to move the code that parses the VLAN keys
earlier than the "goto finished_key_parsing" instruction. This will
ensure that if we have a flower filter with both VLAN and Ethernet
address keys, it won't match on ETYPE 0x8100, because the VLAN key
parsing sets "match_protocol = false".

net: dsa: mt7530: don't change PVC_EG_TAG when CPU port becomes VLAN-aware
Frank reports that in a mt7530 setup where some ports are standalone and
some are in a VLAN-aware bridge, 8021q uppers of the standalone ports
lose their VLAN tag on xmit, as seen by the link partner.
This seems to occur because once the other ports join the VLAN-aware
bridge, mt7530_port_vlan_filtering() also calls
mt7530_port_set_vlan_aware(ds, cpu_dp->index), and this affects the way
that the switch processes the traffic of the standalone port.
Relevant is the PVC_EG_TAG bit. The MT7530 documentation says about it:
EG_TAG: Incoming Port Egress Tag VLAN Attribution
0: disabled (system default)
1: consistent (keep the original ingress tag attribute)
My interpretation is that this setting applies on the ingress port, and
"disabled" is basically the normal behavior, where the egress tag format
of the packet (tagged or untagged) is decided by the VLAN table
(MT7530_VLAN_EGRESS_UNTAG or MT7530_VLAN_EGRESS_TAG).
But there is also an option of overriding the system default behavior,
and for the egress tagging format of packets to be decided not by the
VLAN table, but simply by copying the ingress tag format (if ingress was
tagged, egress is tagged; if ingress was untagged, egress is untagged;
aka "consistent). This is useful in 2 scenarios:
- VLAN-unaware bridge ports will always encounter a miss in the VLAN
table. They should forward a packet as-is, though. So we use
"consistent" there. See commit
e045124e9399 ("net: dsa: mt7530: fix
tagged frames pass-through in VLAN-unaware mode").
- Traffic injected from the CPU port. The operating system is in god
mode; if it wants a packet to exit as VLAN-tagged, it sends it as
VLAN-tagged. Otherwise it sends it as VLAN-untagged*.
*This is true only if we don't consider the bridge TX forwarding offload
feature, which mt7530 doesn't support.
So for now, make the CPU port always stay in "consistent" mode to allow
software VLANs to be forwarded to their egress ports with the VLAN tag
intact, and not stripped.

drm/client: fix circular reference counting issue
We reference dump buffers both by their handle as well as their
object. The problem is now that when anybody iterates over the DRM
framebuffers and exports the underlying GEM objects through DMA-buf
we run into a circular reference count situation.
The result is that the fbdev handling holds the GEM handle preventing
the DMA-buf in the GEM object to be released. This DMA-buf in turn
holds a reference to the driver module which on unload would release
the fbdev.
Break that loop by releasing the handle as soon as the DRM
framebuffer object is created. The DRM framebuffer and the DRM client
buffer structure still hold a reference to the underlying GEM object
preventing its destruction.
