commit ed7f2afdd0 upstream.
The cited commit missed to check against the validity of the frame length
in the tap_get_user_xdp() path, which could cause a corrupted skb to be
sent downstack. Even before the skb is transmitted, the
tap_get_user_xdp()-->skb_set_network_header() may assume the size is more
than ETH_HLEN. Once transmitted, this could either cause out-of-bound
access beyond the actual length, or confuse the underlayer with incorrect
or inconsistent header length in the skb metadata.
In the alternative path, tap_get_user() already prohibits short frame which
has the length less than Ethernet header size from being transmitted.
This is to drop any frame shorter than the Ethernet header size just like
how tap_get_user() does.

commit 66063033f7 upstream.
On some platforms, `char` is unsigned, but this driver, for the most
part, assumed it was signed. In other places, it uses `char` to mean an
unsigned number, but only in cases when the values are small. And in
still other places, `char` is used as a boolean. Put an end to this
confusion by declaring explicit types, depending on the context.

commit 7a99afef17 upstream.
The amount of TX space in the hardware buffer is tracked in the tx_space
variable. The initial value is currently only set during driver probing.
After closing the interface and reopening it the tx_space variable has
the last value it had before close. If it is smaller than the size of
the first send packet after reopeing the interface the queue will be
stopped. The queue is woken up after receiving a TX interrupt but this
will never happen since we did not send anything.
This commit moves the initialization of the tx_space variable to the
ks8851_net_open function right before starting the TX queue. Also query
the value from the hardware instead of using a hard coded value.
Only the SPI chip variant is affected by this issue because only this
driver variant actually depends on the tx_space variable in the xmit
function.

commit 134061163e upstream.
Fix UBSAN warnings that occur when using a system with 32 physical
cpu cores or more, or when the user defines a number of Ethernet
queues greater than or equal to FP_SB_MAX_E1x using the num_queues
module parameter.
Currently there is a read/write out of bounds that occurs on the array
"struct stats_query_entry query" present inside the "bnx2x_fw_stats_req"
struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h".
Looking at the definition of the "struct stats_query_entry query" array:
struct stats_query_entry query[FP_SB_MAX_E1x+
BNX2X_FIRST_QUEUE_QUERY_IDX];
FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts and
has a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3
meaning the array has a total size of 19.
Since accesses to "struct stats_query_entry query" are offset-ted by
BNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernet
queues should not exceed FP_SB_MAX_E1x (16). However one of these queues
is reserved for FCOE and thus the number of Ethernet queues should be set
to [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) if
it is not.
This is also described in a comment in the source code in
drivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definition
of FP_SB_MAX_E1x. Below is the part of this explanation that it important
for this patch
/*
* The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
* control by the number of fast-path status blocks supported by the
* device (HW/FW). Each fast-path status block (FP-SB) aka non-default
* status block represents an independent interrupts context that can
* serve a regular L2 networking queue. However special L2 queues such
* as the FCoE queue do not require a FP-SB and other components like
* the CNIC may consume FP-SB reducing the number of possible L2 queues
*
* If the maximum number of FP-SB available is X then:
* a. If CNIC is supported it consumes 1 FP-SB thus the max number of
* regular L2 queues is Y=X-1
* b. In MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
* c. If the FCoE L2 queue is supported the actual number of L2 queues
* is Y+1
* d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
* slow-path interrupts) or Y+2 if CNIC is supported (one additional
* FP interrupt context for the CNIC).
* e. The number of HW context (CID count) is always X or X+1 if FCoE
* L2 queue is supported. The cid for the FCoE L2 queue is always X.
*/
However this driver also supports NICs that use the E2 controller which can
handle more queues due to having more FP-SB represented by FP_SB_MAX_E2.
Looking at the commits when the E2 support was added, it was originally
using the E1x parameters: commit f2e0899f0f ("bnx2x: Add 57712 support").
Back then FP_SB_MAX_E2 was set to 16 the same as E1x. However the driver
was later updated to take full advantage of the E2 instead of having it be
limited to the capabilities of the E1x. But as far as we can tell, the
array "stats_query_entry query" was still limited to using the FP-SB
available to the E1x cards as part of an oversignt when the driver was
updated to take full advantage of the E2, and now with the driver being
aware of the greater queue size supported by E2 NICs, it causes the UBSAN
warnings seen in the stack traces below.
This patch increases the size of the "stats_query_entry query" array by
replacing FP_SB_MAX_E1x with FP_SB_MAX_E2 to be large enough to handle
both types of NICs.

Commit 205c50306a ("wifi: wilc1000: fix RCU usage in connect path")
made sure that the IEs data was manipulated under the relevant RCU section.
Unfortunately, while doing so, the commit brought a faulty implicit cast
from int to u8 on the ies_len variable, making the parsing fail to be
performed correctly if the IEs block is larger than 255 bytes. This failure
can be observed with Access Points appending a lot of IEs TLVs in their
beacon frames (reproduced with a Pixel phone acting as an Access Point,
which brough 273 bytes of IE data in my testing environment).
Fix IEs parsing by removing this undesired implicit cast.

[ Upstream commit c93a6f62cb ]
On vPro systems, the configuration of the I219-LM to achieve power
gating and S0ix residency is split between the driver and the CSME FW.
It was discovered that in some scenarios, where the network cable is
connected and then disconnected, S0ix residency is not always reached.
This was root-caused to a subset of I219-LM register writes that are not
performed by the CSME FW. Therefore, the driver should perform these
register writes on corporate setups, regardless of the CSME FW state.
This was discovered on Meteor Lake systems; however it is likely to
appear on other platforms as well.

During successful probe, igc logs this:

The reason is that igc_ptp_init() is called very early, even before
register_netdev() has been called. So the netdev_info() call works
on a partially uninitialized netdev.
Fix this by calling igc_ptp_init() after register_netdev(), right

just as in igb.

Instead, use list_first_entry_or_null() which does return NULL if the

[ Upstream commit 49bbeb5719 ]
There are 2 types of outstanding tx skb's:
Type 1: Packets that are sitting in the drivers ind_buff that are
waiting to be batch sent to the NIC. During a device reset, these are
freed with a call to ibmvnic_tx_scrq_clean_buffer()
Type 2: Packets that have been sent to the NIC and are awaiting a TX
completion IRQ. These are free'd during a reset with a call to
clean_tx_pools()
During any reset which requires us to free the tx irq, ensure that the
Type 2 skb references are freed. Since the irq is released, it is
impossible for the NIC to inform of any completions.
Furthermore, later in the reset process is a call to init_tx_pools()
which marks every entry in the tx pool as free (ie not outstanding).
So if the driver is to make a call to init_tx_pools(), it must first
be sure that the tx pool is empty of skb references.
This issue was discovered by observing the following in the logs during
EEH testing:
TX free map points to untracked skb (tso_pool 0 idx=4)
TX free map points to untracked skb (tso_pool 0 idx=5)
TX free map points to untracked skb (tso_pool 1 idx=36)

The very first flush in any port will flush all learned addresses in all
ports. This can be observed by unplugging the cable from one port while
additional ports are connected and dumping the fdb entries.
This problem is caused by the initially wrong value programmed to the
REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and
SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when
ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit
takes effect and flushes all learned entries. After that call both bits
are reset and so the next port flush will not cause such problem again.

[ Upstream commit 604141c036 ]
In virtio spec 0.95, VIRTIO_NET_F_GUEST_CSUM was designed to handle
partially checksummed packets, and the validation of fully checksummed
packets by the device is independent of VIRTIO_NET_F_GUEST_CSUM
negotiation. However, the specification erroneously stated:
"If VIRTIO_NET_F_GUEST_CSUM is not negotiated, the device MUST set flags
to zero and SHOULD supply a fully checksummed packet to the driver."
This statement is inaccurate because even without VIRTIO_NET_F_GUEST_CSUM
negotiation, the device can still set the VIRTIO_NET_HDR_F_DATA_VALID flag.
Essentially, the device can facilitate the validation of these packets'
checksums - a process known as RX checksum offloading - removing the need
for the driver to do so.
This scenario is currently not implemented in the driver and requires
correction. The necessary specification correction[1] has been made and
approved in the virtio TC vote.
