Since commit a18e6521a7d9 ("net: phylink: handle NA interface mode in
phylink_fwnode_phy_connect()"), phylib defaults to GMII when no phy-mode
or phy-connection-type property is specified in a DSA port node of the
device tree. The same commit caused a regression in rtl8365mb whereby
phylink would fail to connect, because the driver did not advertise
support for GMII for ports with internal PHY.
It should be noted that the aforementioned regression is not because the
blamed commit was incorrect: on the contrary, the blamed commit is
correcting the previous behaviour whereby unspecified phy-mode would
cause the internal interface mode to be PHY_INTERFACE_MODE_NA. The
rtl8365mb driver only worked by accident before because it _did_
advertise support for PHY_INTERFACE_MODE_NA, despite NA being reserved
for internal use by phylink. With one mistake fixed, the other was
exposed.
Commit a5dba0f207e5 ("net: dsa: rtl8365mb: add GMII as user port mode")
then introduced implicit support for GMII mode on ports with internal
PHY to allow a PHY connection for device trees where the phy-mode is not
explicitly set to "internal". At this point everything was working OK
again.
Subsequently, commit 6ff6064605e9 ("net: dsa: realtek: convert to
phylink_generic_validate()") broke this behaviour again by discarding
the usage of rtl8365mb_phy_mode_supported() - where this GMII support
was indicated - while switching to the new .phylink_get_caps API.
With the new API, rtl8365mb_phy_mode_supported() is no longer needed.
Remove it altogether and add back the GMII capability - this time to
rtl8365mb_phylink_get_caps() - so that the above default behaviour works
for ports with internal PHY again.

Commit ede359d8843a ("net: dsa: mv88e6xxx: Link in pcs_get_state() if AN
is bypassed") added the ability to link if AN was bypassed, and added
filling of state->an_complete field, but set it to true if AN was
enabled in BMCR, not when AN was reported complete in BMSR.
This was done because for some reason, when I wanted to use BMSR value
to infer an_complete, I was looking at BMSR_ANEGCAPABLE bit (which was
always 1), instead of BMSR_ANEGCOMPLETE bit.
Use BMSR_ANEGCOMPLETE for filling state->an_complete.

If packet headers changed, the cached nfct is no longer relevant
for the packet and attempt to re-use it leads to the incorrect packet
classification.
This issue is causing broken connectivity in OpenStack deployments
with OVS/OVN due to hairpin traffic being unexpectedly dropped.
The setup has datapath flows with several conntrack actions and tuple
changes between them:
actions:ct(commit,zone=8,mark=0/0x1,nat(src)),
set(eth(src=00:00:00:00:00:01,dst=00:00:00:00:00:06)),
set(ipv4(src=172.18.2.10,dst=192.168.100.6,ttl=62)),
ct(zone=8),recirc(0x4)
After the first ct() action the packet headers are almost fully
re-written. The next ct() tries to re-use the existing nfct entry
and marks the packet as invalid, so it gets dropped later in the
pipeline.
Clearing the cached conntrack entry whenever packet tuple is changed
to avoid the issue.
The flow key should not be cleared though, because we should still
be able to match on the ct_state if the recirculation happens after
the tuple change but before the next ct() action.

GRE with TUNNEL_CSUM will apply local checksum offload on
CHECKSUM_PARTIAL packets.
ipgre_xmit must validate csum_start after an optional skb_pull,
else lco_csum may trigger an overflow. The original check was
if (csum && skb_checksum_start(skb) < skb->data)
return -EINVAL;
This had false positives when skb_checksum_start is undefined:
when ip_summed is not CHECKSUM_PARTIAL. A discussed refinement
was straightforward
if (csum && skb->ip_summed == CHECKSUM_PARTIAL &&
skb_checksum_start(skb) < skb->data)
return -EINVAL;
But was eventually revised more thoroughly:
- restrict the check to the only branch where needed, in an
uncommon GRE path that uses header_ops and calls skb_pull.
- test skb_transport_header, which is set along with csum_start
in skb_partial_csum_set in the normal header_ops datapath.
Turns out skbs can arrive in this branch without the transport
header set, e.g., through BPF redirection.
Revise the check back to check csum_start directly, and only if
CHECKSUM_PARTIAL. Do leave the check in the updated location.
Check field regardless of whether TUNNEL_CSUM is configured.

Similar to the handling of play_deferred in commit 19cfe912c37b
("Bluetooth: btusb: Fix memory leak in play_deferred"), we thought
a patch might be needed here as well.
Currently usb_submit_urb is called directly to submit deferred tx
urbs after unanchor them.
So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb
and cause memory leak.
Put those urbs in tx_anchor to avoid the leak, and also fix the error
handling.

The transaction buffer is allocated by using the size of the packet buf,
and subtracting two which seem intended to remove the two tags which are
not present in the target structure. This calculation leads to under
counting memory because of differences between the packet contents and the
target structure. The aid_len field is a u8 in the packet, but a u32 in
the structure, resulting in at least 3 bytes always being under counted.
Further, the aid data is a variable length field in the packet, but fixed
in the structure, so if this field is less than the max, the difference is
added to the under counting.
The last validation check for transaction->params_len is also incorrect
since it employs the same accounting error.
To fix, perform validation checks progressively to safely reach the
next field, to determine the size of both buffers and verify both tags.
Once all validation checks pass, allocate the buffer and copy the data.
This eliminates freeing memory on the error path, as those checks are
moved ahead of memory allocation.

The first validation check for EVT_TRANSACTION has two different checks
tied together with logical AND. One is a check for minimum packet length,
and the other is for a valid aid_tag. If either condition is true (fails),
then an error should be triggered. The fix is to change && to ||.

EXPORT_SYMBOL and __init is a bad combination because the .init.text

xdpxceiver run on a AF_XDP ZC enabled driver revealed a problem with XSK
Tx batching API. There is a test that checks how invalid Tx descriptors
are handled by AF_XDP. Each valid descriptor is followed by invalid one
on Tx side whereas the Rx side expects only to receive a set of valid
descriptors.
In current xsk_tx_peek_release_desc_batch() function, the amount of
available descriptors is hidden inside xskq_cons_peek_desc_batch(). This
can be problematic in cases where invalid descriptors are present due to
the fact that xskq_cons_peek_desc_batch() returns only a count of valid
descriptors. This means that it is impossible to properly update XSK
ring state when calling xskq_cons_release_n().
To address this issue, pull out the contents of
xskq_cons_peek_desc_batch() so that callers (currently only
xsk_tx_peek_release_desc_batch()) will always be able to update the
state of ring properly, as total count of entries is now available and
use this value as an argument in xskq_cons_release_n(). By
doing so, xskq_cons_peek_desc_batch() can be dropped altogether.

When the promiscuous mode is enabled on a VF, the IXGBE_VMOLR_VPE
bit (VLAN Promiscuous Enable) is set. This means that the VF will
receive packets whose VLAN is not the same than the VLAN of the VF.
For instance, in this situation:
┌────────┐ ┌────────┐ ┌────────┐
│ │ │ │ │ │
│ │ │ │ │ │
│ VF0├────┤VF1 VF2├────┤VF3 │
│ │ │ │ │ │
└────────┘ └────────┘ └────────┘
VM1 VM2 VM3
vf 0: vlan 1000
vf 1: vlan 1000
vf 2: vlan 1001
vf 3: vlan 1001
If we tcpdump on VF3, we see all the packets, even those transmitted
on vlan 1000.
This behavior prevents to bridge VF1 and VF2 in VM2, because it will
create a loop: packets transmitted on VF1 will be received by VF2 and
vice-versa, and bridged again through the software bridge.
This patch remove the activation of VLAN Promiscuous when a VF enables
the promiscuous mode. However, the IXGBE_VMOLR_UPE bit (Unicast
Promiscuous) is kept, so that a VF receives all packets that has the
same VLAN, whatever the destination MAC address.

The verifier allows programs to call global functions as long as their
argument types match, using BTF to check the function arguments. One of the
allowed argument types to such global functions is PTR_TO_CTX; however the
check for this fails on BPF_PROG_TYPE_EXT functions because the verifier
uses the wrong type to fetch the vmlinux BTF ID for the program context
type. This failure is seen when an XDP program is loaded using
libxdp (which loads it as BPF_PROG_TYPE_EXT and attaches it to a global XDP
type program).
Fix the issue by passing in the target program type instead of the
BPF_PROG_TYPE_EXT type to bpf_prog_get_ctx() when checking function
argument compatibility.
The first Fixes tag refers to the latest commit that touched the code in
question, while the second one points to the code that first introduced
the global function call verification.

able to see any bounds checking so an integer overflow seems like a
realistic concern.

syzbot reported an illegal copy_to_user() attempt
from bpf_prog_get_info_by_fd() [1]
There was no repro yet on this bug, but I think
that commit 0aef499f3172 ("mm/usercopy: Detect vmalloc overruns")
is exposing a prior bug in bpf arm64.
bpf_prog_get_info_by_fd() looks at prog->jited_len
to determine if the JIT image can be copied out to user space.
My theory is that syzbot managed to get a prog where prog->jited_len
has been set to 43, while prog->bpf_func has ben cleared.
It is not clear why copy_to_user(uinsns, NULL, ulen) is triggering
this particular warning.
I thought find_vma_area(NULL) would not find a vm_struct.
As we do not hold vmap_area_lock spinlock, it might be possible
that the found vm_struct was garbage.

When amt interface receives amt message, it tries to obtain amt private
data from sock.
If there is no amt private data, it frees an skb immediately.
After kfree_skb(), it increases the rx_dropped stats.
But in order to use rx_dropped, amt private data is needed.
So, it makes amt_rcv() to do not increase rx_dropped stats when it can
not obtain amt private data.

There is a limitation in TI DP83867 PHY device where SGMII AN is only
triggered once after the device is booted up. Even after the PHY TPI is
down and up again, SGMII AN is not triggered and hence no new in-band
message from PHY to MAC side SGMII.
This could cause an issue during power up, when PHY is up prior to MAC.
At this condition, once MAC side SGMII is up, MAC side SGMII wouldn`t
receive new in-band message from TI PHY with correct link status, speed
and duplex info.
As suggested by TI, implemented a SW solution here to retrigger SGMII
Auto-Neg whenever there is a link change.

Commit cfc1d277891e ("module: Move all into module/") changed the prefix
of the module param by moving/renaming files. A later commit also moves
the module_param() into a different file, thereby changing the prefix
yet again.
This would break kernel cmdline compatibility and also userspace
compatibility at /sys/module/module/parameters/sig_enforce.
So, set the prefix back to "module.".

GSO assumes skb->head contains link layer headers.

regardless of VLAN being used or not.
After blamed commit, we can end up setting a network
header offset of 18+, we better pull the missing
bytes to avoid a posible crash in GSO.

I have a board where these two lines are always printed during boot:
imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed
It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.
Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.
While here, add the missing \n to one of the format strings.

Global `-Warray-bounds` enablement revealed some problems, one of
which is the way we define and use AQC rules messages.
In fact, they have a shared header, followed by the actual message,
which can be of one of several different formats. So it is
straightforward enough to define that header as a separate struct
and then embed it into message structures as needed, but currently
all the formats reside in one union coupled with the header. Then,
the code allocates only the memory needed for a particular message
format, leaving the union potentially incomplete.
There are no actual reads or writes beyond the end of an allocated
chunk, but at the same time, the whole implementation is fragile and
backed by an equilibrium rather than strong type and memory checks.
Define the structures the other way around: one for the common
header and the rest for the actual formats with the header embedded.
There are no places where several union members would be used at the
same time anyway. This allows to use proper struct_size() and let
the compiler know what is going to be done.
Finally, unsilence `-Warray-bounds` back for ice_switch.c.
Other little things worth mentioning:
* &ice_sw_rule_vsi_list_query is not used anywhere, remove it. It's
weird anyway to talk to hardware with purely kernel types
(bitmaps);
* expand the ICE_SW_RULE_*_SIZE() macros to pass a structure
variable name to struct_size() to let it do strict typechecking;
* rename ice_sw_rule_lkup_rx_tx::hdr to ::hdr_data to keep ::hdr
for the header structure to have the same name for it constistenly
everywhere;
* drop the duplicate of %ICE_SW_RULE_RX_TX_NO_HDR_SIZE residing in
ice_switch.h.

NFDK firmware supports 48-bit dma addressing and
parses 16 high bits of dma addresses.
In nfp_nfdk_tx_desc, dma related structure and tso
related structure are union. When "mss" be filled
with nonzero value due to enable tso, the memory used
by "padding" may be also filled. Then, firmware may
parse wrong dma addresses which causes TX watchdog
timeout problem.
This patch removes padding and unifies the dma_addr_hi
bits with the one in firmware. nfp_nfdk_tx_desc_set_dma_addr
is also added to match this change.
