commit 534fc31d09b706a16d83533e16b5dc855caf7576 upstream.

It is possible that a guest can send a packet that contains a head + 18
slots and yet has a len &lt;= XEN_NETBACK_TX_COPY_LEN. This causes nr_slots
to underflow in xenvif_get_requests() which then causes the subsequent
loop's termination condition to be wrong, causing a buffer overrun of
queue-&gt;tx_map_ops.

Rework the code to account for the extra frag_overflow slots.

This is CVE-2023-34319 / XSA-432.

commit dfd739f182b00b02bd7470ed94d112684cc04fa2 upstream.

The qca8k switch doesn't support using 0 as VID and require a default
VID to be always set. MDB add/del function doesn't currently handle
this and are currently setting the default VID.

Fix this by correctly handling this corner case and internally use the
default VID for VID 0 case.

commit ae70dcb9d9ecaf7d9836d3e1b5bef654d7ef5680 upstream.

On deleting an MDB entry for a port, fdb_search_and_del is used.
An FDB entry can't be modified so it needs to be deleted and readded
again with the new portmap (and the port deleted as requested)

We use the SEARCH operator to search the entry to edit by vid and mac
address and then we check the aging if we actually found an entry.

Currently the code suffer from a bug where the searched fdb entry is
never read again with the found values (if found) resulting in the code
always returning -EINVAL as aging was always 0.

Fix this by correctly read the fdb entry after it was searched.

commit 80248d4160894d7e40b04111bdbaa4ff93fc4bd7 upstream.

On inserting a mdb entry, fdb_search_and_insert is used to add a port to
the qca8k target entry in the FDB db.

A FDB entry can't be modified so it needs to be removed and insert again
with the new values.

To detect if an entry already exist, the SEARCH operation is used and we
check the aging of the entry. If the entry is not 0, the entry exist and
we proceed to delete it.

Current code have 2 main problem:
- The condition to check if the FDB entry exist is wrong and should be
  the opposite.
- When a FDB entry doesn't exist, aging was never actually set to the
  STATIC value resulting in allocating an invalid entry.

Fix both problem by adding aging support to the function, calling the
function with STATIC as aging by default and finally by correct the
condition to check if the entry actually exist.

<content type='text'>
commit 2c39dd025da489cf87d26469d9f5ff19715324a0 upstream.

The qca8xxx switch supports 2 way to write reg values, a slow way using
mdio and a fast way by sending specially crafted mgmt packet to
read/write reg.

The fast way can support up to 32 bytes of data as eth packet are used
to send/receive.

This correctly works for almost the entire regmap of the switch but with
the use of some kernel selftests for dsa drivers it was found a funny
and interesting hw defect/limitation.

For some specific reg, bulk write won't work and will result in writing
only part of the requested regs resulting in half data written. This was
especially hard to track and discover due to the total strangeness of
the problem and also by the specific regs where this occurs.

This occurs in the specific regs of the ATU table, where multiple entry
needs to be written to compose the entire entry.
It was discovered that with a bulk write of 12 bytes on
QCA8K_REG_ATU_DATA0 only QCA8K_REG_ATU_DATA0 and QCA8K_REG_ATU_DATA2
were written, but QCA8K_REG_ATU_DATA1 was always zero.
Tcpdump was used to make sure the specially crafted packet was correct
and this was confirmed.

The problem was hard to track as the lack of QCA8K_REG_ATU_DATA1
resulted in an entry somehow possible as the first bytes of the mac
address are set in QCA8K_REG_ATU_DATA0 and the entry type is set in
QCA8K_REG_ATU_DATA2.

Funlly enough writing QCA8K_REG_ATU_DATA1 results in the same problem
with QCA8K_REG_ATU_DATA2 empty and QCA8K_REG_ATU_DATA1 and
QCA8K_REG_ATU_FUNC correctly written.
A speculation on the problem might be that there are some kind of
indirection internally when accessing these regs and they can't be
accessed all together, due to the fact that it's really a table mapped
somewhere in the switch SRAM.

Even more funny is the fact that every other reg was tested with all
kind of combination and they are not affected by this problem. Read
operation was also tested and always worked so it's not affected by this
problem.

The problem is not present if we limit writing a single reg at times.

To handle this hardware defect, enable use_single_write so that bulk
api can correctly split the write in multiple different operation
effectively reverting to a non-bulk write.

commit e11ec2b868af2b351c6c1e2e50eb711cc5423a10 upstream.

Last year, the code that manages GSI channel transactions switched
from using spinlock-protected linked lists to using indexes into the
ring buffer used for a channel.  Recently, Google reported seeing
transaction reference count underflows occasionally during shutdown.

Doug Anderson found a way to reproduce the issue reliably, and
bisected the issue to the commit that eliminated the linked lists
and the lock.  The root cause was ultimately determined to be
related to unused transactions being committed as part of the modem
shutdown cleanup activity.  Unused transactions are not normally
expected (except in error cases).

The modem uses some ranges of IPA-resident memory, and whenever it
shuts down we zero those ranges.  In ipa_filter_reset_table() a
transaction is allocated to zero modem filter table entries.  If
hashing is not supported, hashed table memory should not be zeroed.
But currently nothing prevents that, and the result is an unused
transaction.  Something similar occurs when we zero routing table
entries for the modem.

By preventing any attempt to clear hashed tables when hashing is not
supported, the reference count underflow is avoided in this case.

Note that there likely remains an issue with properly freeing unused
transactions (if they occur due to errors).  This patch addresses
only the underflows that Google originally reported.

A race were found where set_channels could be called after registering
but before virtnet_set_queues() in virtnet_probe(). Fixing this by
moving the virtnet_set_queues() before netdevice registering. While at
it, use _virtnet_set_queues() to avoid holding rtnl as the device is
not even registered at that time.

commit f8a2da6ec2417cca169fa85a8ab15817bccbb109 upstream.

After an initial link up the CAN device is in ERROR-ACTIVE mode. Due
to a missing CAN_STATE_STOPPED in gs_can_close() it doesn't change to
STOPPED after a link down:

| ip link set dev can0 up
| ip link set dev can0 down
| ip --details link show can0
| 13: can0: &lt;NOARP,ECHO&gt; mtu 16 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 10
|     link/can  promiscuity 0 allmulti 0 minmtu 0 maxmtu 0
|     can state ERROR-ACTIVE restart-ms 1000

Add missing assignment of CAN_STATE_STOPPED in gs_can_close().

[ Upstream commit 5c85f7065718a949902b238a6abd8fc907c5d3e0 ]

in be_lancer_xmit_workarounds(), it should go to label 'tx_drop'
if an unexpected value is returned by pskb_trim().

<title>net: fec: tx processing does not call XDP APIs if budget is 0</title>

[ Upstream commit 15cec633fc7bfe4cd69aa012c3b35b31acfc86f2 ]

According to the clarification [1] in the latest napi.rst, the tx
processing cannot call any XDP (or page pool) APIs if the "budget"
is 0. Because NAPI is called with the budget of 0 (such as netpoll)
indicates we may be in an IRQ context, however, we cannot use the
page pool from IRQ context.
