[ Upstream commit 79498d5af8e458102242d1667cf44df1f1564e63 ]
The ice_vc_send_msg_to_vf function has logic to detect "failure"
responses being sent to a VF. If a VF is sent more than
ICE_DFLT_NUM_INVAL_MSGS_ALLOWED then the VF is marked as disabled.
Almost identical logic also existed in the i40e driver.
This logic was added to the ice driver in commit 1071a8358a ("ice:
Implement virtchnl commands for AVF support") which itself copied from
the i40e implementation in commit 5c3c48ac6b ("i40e: implement virtual
device interface").
Neither commit provides a proper explanation or justification of the
check. In fact, later commits to i40e changed the logic to allow
bypassing the check in some specific instances.
The "logic" for this seems to be that error responses somehow indicate a
malicious VF. This is not really true. The PF might be sending an error
for any number of reasons such as lack of resources, etc.
Additionally, this causes the PF to log an info message for every failed
VF response which may confuse users, and can spam the kernel log.
This behavior is not documented as part of any requirement for our
products and other operating system drivers such as the FreeBSD
implementation of our drivers do not include this type of check.
In fact, the change from dev_err to dev_info in i40e commit 18b7af57d9
("i40e: Lower some message levels") explains that these messages
typically don't actually indicate a real issue. It is quite likely that
a user who hits this in practice will be very confused as the VF will be
disabled without an obvious way to recover.
We already have robust malicious driver detection logic using actual
hardware detection mechanisms that detect and prevent invalid device
usage. Remove the logic since its not a documented requirement and the
behavior is not intuitive.

commit fadead80fe4c033b5e514fcbadd20b55c4494112 upstream.
Commit c503e63200c6 ("ice: Stop processing VF messages during teardown")
introduced a driver state flag, ICE_VF_DEINIT_IN_PROGRESS, which is
intended to prevent some issues with concurrently handling messages from
VFs while tearing down the VFs.
This change was motivated by crashes caused while tearing down and
bringing up VFs in rapid succession.
It turns out that the fix actually introduces issues with the VF driver
caused because the PF no longer responds to any messages sent by the VF
during its .remove routine. This results in the VF potentially removing
its DMA memory before the PF has shut down the device queues.
Additionally, the fix doesn't actually resolve concurrency issues within
the ice driver. It is possible for a VF to initiate a reset just prior
to the ice driver removing VFs. This can result in the remove task
concurrently operating while the VF is being reset. This results in
similar memory corruption and panics purportedly fixed by that commit.
Fix this concurrency at its root by protecting both the reset and
removal flows using the existing VF cfg_lock. This ensures that we
cannot remove the VF while any outstanding critical tasks such as a
virtchnl message or a reset are occurring.
This locking change also fixes the root cause originally fixed by commit
c503e63200c6 ("ice: Stop processing VF messages during teardown"), so we
can simply revert it.
Note that I kept these two changes together because simply reverting the
original commit alone would leave the driver vulnerable to worse race
conditions.

commit e6ba5273d4ede03d075d7a116b8edad1f6115f4d upstream.
The VF can be configured via the PF's ndo ops at the same time the PF is
receiving/handling virtchnl messages. This has many issues, with
one of them being the ndo op could be actively resetting a VF (i.e.
resetting it to the default state and deleting/re-adding the VF's VSI)
while a virtchnl message is being handled. The following error was seen
because a VF ndo op was used to change a VF's trust setting while the
VIRTCHNL_OP_CONFIG_VSI_QUEUES was ongoing:
[35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM
[35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5
[35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6
Fix this by making sure the virtchnl handling and VF ndo ops that
trigger VF resets cannot run concurrently. This is done by adding a
struct mutex cfg_lock to each VF structure. For VF ndo ops, the mutex
will be locked around the critical operations and VFR. Since the ndo ops
will trigger a VFR, the virtchnl thread will use mutex_trylock(). This
is done because if any other thread (i.e. VF ndo op) has the mutex, then
that means the current VF message being handled is no longer valid, so
just ignore it.
This issue can be seen using the following commands:
for i in {0..50}; do
rmmod ice
modprobe ice

The driver was avoiding offload for IPIP (at least) frames due to
parsing the inner header offsets incorrectly when trying to check
lengths.
This length check works for VXLAN frames but fails on IPIP frames
because skb_transport_offset points to the inner header in IPIP
frames, which meant the subtraction of transport_header from
inner_network_header returns a negative value (-20).
With the code before this patch, everything continued to work, but GSO
was being used to segment, causing throughputs of 1.5Gb/s per thread.
After this patch, throughput is more like 10Gb/s per thread for IPIP
traffic.

When a VF is removed and/or reset its Tx queues need to be
stopped from the PF. This is done by calling the ice_dis_vf_qs()
function, which calls ice_vsi_stop_lan_tx_rings(). Currently
ice_dis_vf_qs() is protected by the VF state bit ICE_VF_STATE_QS_ENA.
Unfortunately, this is causing the Tx queues to not be disabled in some
cases and when the VF tries to re-enable/reconfigure its Tx queues over
virtchnl the op is failing. This is because a VF can be reset and/or
removed before the ICE_VF_STATE_QS_ENA bit is set, but the Tx queues
were already configured via ice_vsi_cfg_single_txq() in the
VIRTCHNL_OP_CONFIG_VSI_QUEUES op. However, the ICE_VF_STATE_QS_ENA bit
is set on a successful VIRTCHNL_OP_ENABLE_QUEUES, which will always
happen after the VIRTCHNL_OP_CONFIG_VSI_QUEUES op.
This was causing the following error message when loading the ice
driver, creating VFs, and modifying VF trust in an endless loop:
[35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM
[35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5
[35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6
Fix this by always calling ice_dis_vf_qs() and silencing the error
message in ice_vsi_stop_tx_ring() since the calling code ignores the
return anyway. Also, all other places that call ice_vsi_stop_tx_ring()
catch the error, so this doesn't affect those flows since there was no
change to the values the function returns.
Other solutions were considered (i.e. tracking which VF queues had been
"started/configured" in VIRTCHNL_OP_CONFIG_VSI_QUEUES, but it seemed
more complicated than it was worth. This solution also brings in the
chance for other unexpected conditions due to invalid state bit checks.
So, the proposed solution seemed like the best option since there is no
harm in failing to stop Tx queues that were never started.
This issue can be seen using the following commands:
for i in {0..50}; do
rmmod ice
modprobe ice

In some circumstances, such as with bridging, it's possible that the
stack will add the device's own MAC address to its unicast address list.
If, later, the stack deletes this address, the driver will receive a
request to remove this address.
The driver stores its current MAC address as part of the VSI MAC filter
list instead of separately. So, this causes a problem when the device's
MAC address is deleted unexpectedly, which results in traffic failure in
some cases.
The following configuration steps will reproduce the previously
mentioned problem:
> ip link set eth0 up
> ip link add dev br0 type bridge
> ip link set br0 up
> ip addr flush dev eth0
> ip link set eth0 master br0
> echo 1 > /sys/class/net/br0/bridge/vlan_filtering
> modprobe -r veth
> modprobe -r bridge
> ip addr add 192.168.1.100/24 dev eth0
The following ping command fails due to the netdev->dev_addr being
deleted when removing the bridge module.
> ping <link partner>
Fix this by making sure to not delete the netdev->dev_addr during MAC
address sync. After fixing this issue it was noticed that the
netdev_warn() in .set_mac was overly verbose, so make it at
netdev_dbg().
Also, there is a possibility of a race condition between .set_mac and
.set_rx_mode. Fix this by calling netif_addr_lock_bh() and
netif_addr_unlock_bh() on the device's netdev when the netdev->dev_addr
is going to be updated in .set_mac.

Currently in the ice driver, the check whether to
allow a LLDP packet to egress the interface from the
PF_VSI is being based on the SKB's priority field.
It checks to see if the packets priority is equal to
TC_PRIO_CONTROL. Injected LLDP packets do not always
meet this condition.
SCAPY defaults to a sk_buff->protocol value of ETH_P_ALL
(0x0003) and does not set the priority field. There will
be other injection methods (even ones used by end users)
that will not correctly configure the socket so that
SKB fields are correctly populated.
Then ethernet header has to have to correct value for
the protocol though.
Add a check to also allow packets whose ethhdr->h_proto
matches ETH_P_LLDP (0x88CC).

a u32 cmp_dcbcfg->numapp to check for the end of the loop. If
cmp_dcbcfg->numapp is larger than 255 then the counter j will wrap
around to zero and hence an infinite loop occurs. Fix this by making

implementation, the ice_aqc_opc_get_cee_dcb_cfg (0x0A07) AQ command
doesn't provide a way to communicate the protocol port number to the

commit 1831da7ea5bdf5531d78bcf81f526faa4c4375fa upstream.
In ice_suspend(), ice_clear_interrupt_scheme() is called, and then
irq_free_descs() will be eventually called to free irq and its descriptor.
In ice_resume(), ice_init_interrupt_scheme() is called to allocate new
irqs. However, in ice_rebuild_arfs(), struct irq_glue and struct cpu_rmap
maybe cannot be freed, if the irqs that released in ice_suspend() were
reassigned to other devices, which makes irq descriptor's affinity_notify
lost.
So call ice_free_cpu_rx_rmap() before ice_clear_interrupt_scheme(), which
can make sure all irq_glue and cpu_rmap can be correctly released before
corresponding irq and descriptor are released.
Fix the following memory leak.

commit 741b7b743bbcb5a3848e4e55982064214f900d2f upstream.
The original purpose of the ICE_DCBNL_DEVRESET was to protect
the driver during DCBNL device resets. But, the flow for
DCBNL device resets now consists of only calls up the stack
such as dev_close() and dev_open() that will result in NDO calls
to the driver. These will be handled with state changes from the
stack. Also, there is a problem of the dev_close and dev_open
being blocked by checks for reset in progress also using the
ICE_DCBNL_DEVRESET bit.
Since the ICE_DCBNL_DEVRESET bit is not necessary for protecting
the driver from DCBNL device resets and it is actually blocking
changes coming from the DCBNL interface, remove the bit from the
PF state and don't block driver function based on DCBNL reset in
progress.

commit e95fc8573e07c5e4825df4650fd8b8c93fad27a7 upstream.
There is a possibility of race between ice_open or ice_stop calls
performed by OS and reset handling routine both trying to modify VSI
resources. Observed scenarios:
- reset handler deallocates memory in ice_vsi_free_arrays and ice_open
tries to access it in ice_vsi_cfg_txq leading to driver crash
- reset handler deallocates memory in ice_vsi_free_arrays and ice_close
tries to access it in ice_down leading to driver crash
- reset handler clears port scheduler topology and sets port state to
ICE_SCHED_PORT_STATE_INIT leading to ice_ena_vsi_txq fail in ice_open
To prevent this additional checks in ice_open and ice_stop are
introduced to make sure that OS is not allowed to alter VSI config while
reset is in progress.
