commit 6cf87e5edd9944e1d3b6efd966ea401effc304ee upstream.
There exist many FT2232-based JTAG+UART adapter designs in which
FT2232 Channel A is used for JTAG and Channel B is used for UART.
The best way to handle them in Linux is to have the ftdi_sio driver
create a ttyUSB device only for Channel B and not for Channel A:
a ttyUSB device for Channel A would be bogus and will disappear as
soon as the user runs OpenOCD or other applications that access
Channel A for JTAG from userspace, causing undesirable noise for
users. The ftdi_sio driver already has a dedicated quirk for such
JTAG+UART FT2232 adapters, and it requires assigning custom USB IDs
to such adapters and adding these IDs to the driver with the
ftdi_jtag_quirk applied.
Boutique hardware manufacturer Falconia Partners LLC has created a
couple of JTAG+UART adapter designs (one buffered, one unbuffered)
as part of FreeCalypso project, and this hardware is specifically made
to be used with Linux hosts, with the intent that Channel A will be
accessed only from userspace via appropriate applications, and that
Channel B will be supported by the ftdi_sio kernel driver, presenting
a standard ttyUSB device to userspace. Toward this end the hardware
manufacturer will be programming FT2232 EEPROMs with custom USB IDs,
specifically with the intent that these IDs will be recognized by
the ftdi_sio driver with the ftdi_jtag_quirk applied.

commit e1f13c879a7c21bd207dc6242455e8e3a1e88b40 upstream.
While finding usb endpoints in vmk80xx_find_usb_endpoints(), check if
wMaxPacketSize = 0 for the endpoints found.
Some devices have isochronous endpoints that have wMaxPacketSize = 0
(as required by the USB-2 spec).
However, since this doesn't apply here, wMaxPacketSize = 0 can be
considered to be invalid.

The setkey function for GCM/CCM algorithms didn't verify the key
length before copying the key and subtracting the salt length.
This patch delays the copying of the key til after the verification
has been done. It also adds checks on the key length to ensure
that it's at least as long as the salt.

commit f45a4248ea4cc13ed50618ff066849f9587226b2 upstream.
When get_registers() fails in set_ethernet_addr(),the uninitialized
value of node_id gets copied over as the address.
So, check the return value of get_registers().
If get_registers() executed successfully (i.e., it returns
sizeof(node_id)), copy over the MAC address using ether_addr_copy()
(instead of using memcpy()).
Else, if get_registers() failed instead, a randomly generated MAC
address is set as the MAC address instead.

commit 44c413d9a51752056d606bf6f312003ac1740fab upstream.
The tty TIOCL_SETSEL ioctl allocates a memory buffer big enough for text
selection area. The maximum allowed console size is
VC_RESIZE_MAXCOL * VC_RESIZE_MAXROW == 32767*32767 == ~1GB and typical
MAX_ORDER is set to allow allocations lot less than than (circa 16MB).
So it is quite possible to trigger huge allocation (and syzkaller just
did that) which is going to fail (which is fine) with a backtrace in
mm/page_alloc.c at WARN_ON_ONCE(!(gfp_mask & __GFP_NOWARN)) and
this may trigger panic (if panic_on_warn is enabled) and
leak kernel addresses to dmesg.
This passes __GFP_NOWARN to kmalloc_array to avoid unnecessary user-
triggered WARN_ON. Note that the error is not ignored and
the warning is still printed.

complain from __blkdev_issue_discard() for the improper value of discard
granularity.
This issue is exposed after commit b35fd7422c2f ("block: check queue's

[ Upstream commit 601e984f23abcaa7cf3eb078c13de4db3cf6a4f0 ]
Tail dropping is enabled for a port when:
1. A source port consumes more packet buffers than the watermark encoded
in SYS:PORT:ATOP_CFG.ATOP.
AND
2. Total memory use exceeds the consumption watermark encoded in
SYS:PAUSE_CFG:ATOP_TOT_CFG.
The unit of these watermarks is a 60 byte memory cell. That unit is
programmed properly into ATOP_TOT_CFG, but not into ATOP. Actually when
written into ATOP, it would get truncated and wrap around.

Pinned pages are not properly accounted particularly when
mapping error occurs on IOTLB update. Clean up dangling
pinned pages for the error path. As the inflight pinned
pages, specifically for memory region that strides across
multiple chunks, would need more than one free page for
book keeping and accounting. For simplicity, pin pages
for all memory in the IOVA range in one go rather than
have multiple pin_user_pages calls to make up the entire
region. This way it's easier to track and account the
pages already mapped, particularly for clean-up in the
error path.

[ Upstream commit 388e201d41fa1ed8f2dce0f0567f56f8e919ffb0 ]
Ethtool manual stated that the tx-timer is the "the amount of time the
device should stay in idle mode prior to asserting its Tx LPI". The
previous implementation for "ethtool --set-eee tx-timer" sets the LPI TW
timer duration which is not correct. Hence, this patch fixes the
"ethtool --set-eee tx-timer" to configure the EEE LPI timer.
The LPI TW Timer will be using the defined default value instead of
"ethtool --set-eee tx-timer" which follows the EEE LS timer implementation.
Changelog V2
*Not removing/modifying the eee_timer.
*EEE LPI timer can be configured through ethtool and also the eee_timer
module param.
*EEE TW Timer will be configured with default value only, not able to be

[ Upstream commit 1253935ad801485270194d5651acab04abc97b36 ]
Current neigh update event handler implementation takes reference to
neighbour structure, assigns it to nhe->n, tries to schedule workqueue task
and releases the reference if task was already enqueued. This results
potentially overwriting existing nhe->n pointer with another neighbour
instance, which causes double release of the instance (once in neigh update
handler that failed to enqueue to workqueue and another one in neigh update
workqueue task that processes updated nhe->n pointer instead of original
one):

When interface is attached while in promiscuous mode and with VLAN
filtering turned off, both configurations are not respected and VLAN
filtering is performed.
There are 2 flows which add the any-vid rules during interface attach:
VLAN creation table and set rx mode. Each is relaying on the other to
add any-vid rules, eventually non of them does.
Fix this by adding any-vid rules on VLAN creation regardless of
promiscuous mode.

[ Upstream commit 8c7353b6f716436ad0bfda2b5c5524ab2dde5894 ]
Prior to this patch unloading an interface in promiscuous mode with RX
VLAN filtering feature turned off - resulted in a warning. This is due
to a wrong condition in the VLAN rules cleanup flow, which left the
any-vid rules in the VLAN steering table. These rules prevented
destroying the flow group and the flow table.
The any-vid rules are removed in 2 flows, but none of them remove it in
case both promiscuous is set and VLAN filtering is off. Fix the issue by
changing the condition of the VLAN table cleanup flow to clean also in
case of promiscuous mode.

[ Upstream commit c3c9402373fe20e2d08c04f437ce4dcd252cffb2 ]
Prior to this fix, in Striding RQ mode the driver was vulnerable when
receiving packets in the range (stride size - headroom, stride size].
Where stride size is calculated by mtu+headroom+tailroom aligned to the
closest power of 2.
Usually, this filtering is performed by the HW, except for a few cases:
- Between 2 VFs over the same PF with different MTUs
- On bluefield, when the host physical function sets a larger MTU than
the ARM has configured on its representor and uplink representor.
When the HW filtering is not present, packets that are larger than MTU
might be harmful for the RQ's integrity, in the following impacts:
1) Overflow from one WQE to the next, causing a memory corruption that
in most cases is unharmful: as the write happens to the headroom of next
packet, which will be overwritten by build_skb(). In very rare cases,
high stress/load, this is harmful. When the next WQE is not yet reposted
and points to existing SKB head.
2) Each oversize packet overflows to the headroom of the next WQE. On
the last WQE of the WQ, where addresses wrap-around, the address of the
remainder headroom does not belong to the next WQE, but it is out of the
memory region range. This results in a HW CQE error that moves the RQ
into an error state.
Solution:
Add a page buffer at the end of each WQE to absorb the leak. Actually
the maximal overflow size is headroom but since all memory units must be
of the same size, we use page size to comply with UMR WQEs. The increase
in memory consumption is of a single page per RQ. Initialize the mkey
with all MTTs pointing to a default page. When the channels are
activated, UMR WQEs will redirect the RX WQEs to the actual memory from
the RQ's pool, while the overflow MTTs remain mapped to the default page.

[ Upstream commit 1d5558b1f0de81f54ddee05f3793acc5260d107f ]
Once driver detects a command interface command timeout, it warns the
user and returns timeout error to the caller. In such case, the entry of
the command is not evacuated (because only real event interrupt is allowed
to clear command interface entry). If the HW event interrupt
of this entry will never arrive, this entry will be left unused forever.
Command interface entries are limited and eventually we can end up without
the ability to post a new command.
In addition, if driver will not consume the EQE of the lost interrupt and
rearm the EQ, no new interrupts will arrive for other commands.
Add a resiliency mechanism for manually polling the command EQ in case of
a command timeout. In case resiliency mechanism will find non-handled EQE,
it will consume it, and the command interface will be fully functional
again. Once the resiliency flow finished, wait another 5 seconds for the
command interface to complete for this command entry.
Define mlx5_cmd_eq_recover() to manage the cmd EQ polling resiliency flow.
Add an async EQ spinlock to avoid races between resiliency flows and real
interrupts that might run simultaneously.

[ Upstream commit 50b2412b7e7862c5af0cbf4b10d93bc5c712d021 ]
Upon command completion timeout, driver simulates a forced command
completion. In a rare case where real interrupt for that command arrives
simultaneously, it might release the command entry while the forced
handler might still access it.
Fix that by adding an entry refcount, to track current amount of allowed
handlers. Command entry to be released only when this refcount is
decremented to zero.
Command refcount is always initialized to one. For callback commands,
command completion handler is the symmetric flow to decrement it. For
non-callback commands, it is wait_func().
Before ringing the doorbell, increment the refcount for the real completion
handler. Once the real completion handler is called, it will decrement it.
For callback commands, once the delayed work is scheduled, increment the
refcount. Upon callback command completion handler, we will try to cancel
the timeout callback. In case of success, we need to decrement the callback
refcount as it will never run.
In addition, gather the entry index free and the entry free into a one
flow for all command types release.

As part of driver unload, it destroys the commands EQ (via FW command).
As the commands EQ is destroyed, FW will not generate EQEs for any command
that driver sends afterwards. Driver should poll for later commands status.
Driver commands mode metadata is updated before the commands EQ is
actually destroyed. This can lead for double completion handle by the
driver (polling and interrupt), if a command is executed and completed by
FW after the mode was changed, but before the EQ was destroyed.

[ Upstream commit 66a5209b53418111757716d71e52727b782eabd4 ]
Mbox implementation in octeontx2 driver has three states
alloc, send and reset in mbox response. VF allocate and
sends message to PF for processing, PF ACKs them back and
reset the mbox memory. In some case we see synchronization
issue where after msgs_acked is incremented and before
mbox_reset API is called, if current execution is scheduled
out and a different thread is scheduled in which checks for
msgs_acked. Since the new thread sees msgs_acked == msgs_sent
it will try to allocate a new message and to send a new mbox
message to PF.Now if mbox_reset is scheduled in, PF will see
'0' in msgs_send.
This patch fixes the issue by calling mbox_reset before
incrementing msgs_acked flag for last processing message and
checks for valid message size.

interfaces so that broadcast packets are sent
to all interfaces present in the list. It is
driver job to add and delete a PF/VF interface
to/from the list when the interface is brought
up and down. This patch fixes the
npc_enadis_default_entries function to handle
broadcast replication properly if packet replication
feature is present.

[ Upstream commit bbc4d71d63549bcd003a430de18a72a742d8c91e ]
There are two chip pins named TXDLY and RXDLY which actually adds the 2ns
delays to TXC and RXC for TXD/RXD latching. These two pins can config via
4.7k-ohm resistor to 3.3V hw setting, but also config via software setting
(extension page 0xa4 register 0x1c bit13 12 and 11).
The configuration register definitions from table 13 official PHY datasheet:
PHYAD[2:0] = PHY Address
AN[1:0] = Auto-Negotiation
Mode = Interface Mode Select
RX Delay = RX Delay
TX Delay = TX Delay
SELRGV = RGMII/GMII Selection
This table describes how to config these hw pins via external pull-high or pull-
low resistor.
It is a misunderstanding that mapping it as register bits below:
8:6 = PHY Address
5:4 = Auto-Negotiation
3 = Interface Mode Select
2 = RX Delay
1 = TX Delay
0 = SELRGV
So I removed these descriptions above and add related settings as below:
14 = reserved
13 = force Tx RX Delay controlled by bit12 bit11
12 = Tx Delay
11 = Rx Delay
10:0 = Test && debug settings reserved by realtek
Test && debug settings are not recommend to modify by default.

Open vSwitch and Linux bridge will disable LRO of the interface
when this interface added to them. Now when disable the LRO, the
virtio-net csum is disable too. That drops the forwarding performance.

If mlxsw_sp_acl_tcam_group_id_get() fails, the mutex initialized earlier
is not destroyed.
Fix this by initializing the mutex after calling the function. This is
symmetric to mlxsw_sp_acl_tcam_group_del().

[ Upstream commit f32f19339596b214c208c0dba716f4b6cc4f6958 ]
syzbot managed to crash a host by creating a bond
with a GRE device.
For non Ethernet device, bonding calls bond_setup_by_slave()
instead of ether_setup(), and unfortunately dev->needed_headroom
was not copied from the new added member.

To start also "phy state machine", with UP state as it should be,
the phy_start() has to be used, in another case machine even is not
triggered. After this change negotiation is supposed to be triggered
by SM workqueue.
It's not correct usage, but it appears after the following patch,
so add it as a fix.
