The descriptor list is a shared resource across all of the transmit queues, and
the locking mechanism used today only protects concurrency across a given
transmit queue between the transmit and reclaiming. This creates an opportunity
for the SYSTEMPORT hardware to work on corrupted descriptors if we have
multiple producers at once which is the case when using multiple transmit
queues.
This was particularly noticeable when using multiple flows/transmit queues and
it showed up in interesting ways in that UDP packets would get a correct UDP
header checksum being calculated over an incorrect packet length. Similarly TCP
packets would get an equally correct checksum computed by the hardware over an
incorrect packet length.
The SYSTEMPORT hardware maintains an internal descriptor list that it re-arranges
when the driver produces a new descriptor anytime it writes to the
WRITE_PORT_{HI,LO} registers, there is however some delay in the hardware to
re-organize its descriptors and it is possible that concurrent TX queues
eventually break this internal allocation scheme to the point where the
length/status part of the descriptor gets used for an incorrect data buffer.
The fix is to impose a global serialization for all TX queues in the short
section where we are writing to the WRITE_PORT_{HI,LO} registers which solves
the corruption even with multiple concurrent TX queues being used.

This issue dues to flush_work(), which is used to wait for
smc_connect_work() to finish in smc_release(). Once lots of
smc_connect_work() was pending or all executing work dangling,
smc_release() has to block until one worker comes to free, which
is equivalent to wait another smc_connnect_work() to finish.
In order to fix this, There are two changes:
1. For those idle smc_connect_work(), cancel it from the workqueue; for
executing smc_connect_work(), waiting for it to finish. For that
purpose, replace flush_work() with cancel_work_sync().
2. Since smc_connect() hold a reference for passive closing, if
smc_connect_work() has been cancelled, release the reference.

The prima driver facilitates the direct programming of beacon filter tables via
SMD commands.
The purpose of beacon filters is quote:
/* When beacon filtering is enabled, firmware will
* analyze the selected beacons received during BMPS,
* and monitor any changes in the IEs as listed below.
* The format of the table is:
* - EID
* - Check for IE presence
* - Byte offset
* - Byte value
* - Bit Mask
* - Byte reference
*/
The default filter table looks something like this:
tBeaconFilterIe gaBcnFilterTable[12] =
{
{ WLAN_EID_DS_PARAMS, 0u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_ERP_INFO, 0u, { 0u, 0u, 248u, 0u } },
{ WLAN_EID_EDCA_PARAM_SET, 0u, { 0u, 0u, 240u, 0u } },
{ WLAN_EID_QOS_CAPA, 0u, { 0u, 0u, 240u, 0u } },
{ WLAN_EID_CHANNEL_SWITCH, 1u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_QUIET, 1u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_HT_OPERATION, 0u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_HT_OPERATION, 0u, { 1u, 0u, 248u, 0u } },
{ WLAN_EID_HT_OPERATION, 0u, { 2u, 0u, 235u, 0u } },
{ WLAN_EID_HT_OPERATION, 0u, { 5u, 0u, 253u, 0u } },
{ WLAN_EID_PWR_CONSTRAINT, 0u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_OPMODE_NOTIF, 0u, { 0u, 0u, 0u, 0u } }
};
Add in an equivalent filter set as present in the prima Linux driver.
For now omit the beacon filter "rem" command as the driver does not have an
explicit call to that SMD command. The filter mask should only count when
we are inside BMPS anyway.
Replicating the ability to program the filter table gives us scope to add and
remove elements in future. For now though this patch makes the rote-copy of the
downstream Linux beacon filter table, which we can tweak as desired from now
on.

This series merges the different (largely identical) nla policies.
v2 also squashed the ->suppress() implementation, I've dropped this.
Problem is that it needs ugly ifdef'ry to avoid build breakage
with CONFIG_INET=n || IPV6=n.
Given that even microbenchmark doesn't show any noticeable improvement
when ->suppress is inlined (it uses INDIRECT_CALLABLE) i decided to toss
the patch instead of adding more ifdefs.

Add user template explicit support. At this moment, max
TCAM rule size is utilized for all rules, doesn't matter
which and how much flower matches are provided by user. It
means that some of TCAM space is wasted, which impacts
the number of filters that can be offloaded.
Introducing the template, allows to have more HW offloaded
filters by specifying the template explicitly.
Example:
tc qd add dev PORT clsact
tc chain add dev PORT ingress protocol ip \
flower dst_ip 0.0.0.0/16
tc filter add dev PORT ingress protocol ip \
flower skip_sw dst_ip 1.2.3.4/16 action drop
NOTE: chain 0 is the default chain id for "tc chain" & "tc filter"

Allow drivers to pass metadata along with packet data to the device.
Introduce a new metadata descriptor type
* GVE_TXD_MTD
This descriptor is optional. If present it immediate follows the
packet descriptor and precedes the segment descriptor.
This descriptor may be repeated. Multiple metadata descriptors may
follow. There are no immediate uses for this, this is for future
proofing. At present devices allow only 1 MTD descriptor.
The lower four bits of the type_flags field encode GVE_TXD_MTD.
The upper four bits of the type_flags field encodes a *sub*type.
Introduce one such metadata descriptor subtype
* GVE_MTD_SUBTYPE_PATH
This shares path information with the device for network failure
discovery and robust response:
Linux derives ipv6 flowlabel and ECMP multipath from sk->sk_txhash,
and updates this field on error with sk_rethink_txhash. Allow the host
stack to do the same. Pass the tx_hash value if set. Also communicate
whether the path hash is set, or more exactly, what its type is. Define
two common types
GVE_MTD_PATH_HASH_NONE
GVE_MTD_PATH_HASH_L4
Concrete examples of error conditions that are resolved are
mentioned in the commits that add sk_rethink_txhash calls. Such as
commit 7788174e87 ("tcp: change IPv6 flow-label upon receiving
spurious retransmission").
Experimental results mirror what the theory suggests: where IPv6
FlowLabel is included in path selection (e.g., LAG/ECMP), flowlabel
rotation on TCP timeout avoids the vast majority of TCP disconnects
that would otherwise have occurred during link failures in long-haul
backbones, when an alternative path is available.
Rotation can be applied to various bad connection signals, such as
timeouts and spurious retransmissions. In aggregate, such flow level
signals can help locate network issues. Define initial common states:
GVE_MTD_PATH_STATE_DEFAULT
GVE_MTD_PATH_STATE_TIMEOUT

The legacy raw addressing device option was processed before the
new RDA queue format option. This caused the supported features mask,
which is provided only on the RDA queue format option, not to be set.
This disabled jumbo-frame support when using raw adressing.

net: phylink: add PCS validation
This series allows phylink to include the PCS in its validation step.
There are two reasons to make this change:
1. Some of the network drivers that are making use of the split PCS
support are already manually calling into their PCS drivers to
perform validation. E.g. stmmac with xpcs.
2. Logically, some network drivers such as mvneta and mvpp2, the
restriction we impose in the validate() callback is a property of
the "PCS" block that we provide rather than the MAC.
This series:
1. Gives phylink a mechanism to query the MAC driver which PCS is
wishes to use for the PHY interface mode. This is necessary to allow
the PCS to be involved in the validation step without making changes
to the configuration.
2. Provide a pcs_validate() method that PCS can implement. This follows
a similar model to the MAC's validate() callback, but with some minor
differences due to observations from the various implementations.
E.g. returning an error code for not-supported and the way the
advertising bitmap is masked.
3. Convert mvpp2 and mvneta to this as examples of its use. Further
Conversions are in the pipeline, including for stmmac+xpcs, as well
as some DSA drivers. Note that DSA conversion to this is conditional
upon all DSA drivers populating their supported_interfaces bitmap,
since this is required before mac_select_pcs() can be used.
Existing drivers that set a PCS in mac_prepare() or mac_config(), or
shortly after phylink_create() will continue to work. However, it should
be noted that mac_select_pcs() will be called during phylink_create(),
and thus any PCS returned by mac_select_pcs() must be available by this
time - or we drop the check in phylink_create().

Convert mvneta to validate the autoneg state for 1000base-X in the
pcs_validate() operation, rather than the MAC validate() operation.
This allows us to switch the MAC validate() to use
phylink_generic_validate().

Add a hook for PCS to validate the link parameters. This avoids MAC

mac_select_pcs() allows us to have an explicit point to query which
PCS the MAC wishes to use for a particular PHY interface mode, thereby
allowing us to add support to validate the link settings with the PCS.
Phylink will also use this to select the PCS to be used during a major
configuration event without the MAC driver needing to call
phylink_set_pcs().
Note that if mac_select_pcs() is present, the supported_interfaces
bitmap must be filled in; this avoids mac_select_pcs() being called
with PHY_INTERFACE_MODE_NA when we want to get support for all
interface types. Phylink will return an error in phylink_create()
unless this condition is satisfied.

100GbE Intel Wired LAN Driver Updates 2021-12-15
This series contains updates to ice driver only.
Jake makes changes to flash update. This includes the following:
* a new shadow-ram region similar to NVM region but for the device shadow
RAM contents. This is distinct from NVM region because shadow RAM is
built up during device init and may be different from the raw NVM flash
data.
* refactoring of the ice_flash_pldm_image to become the main flash update
entry point. This is simpler than having both an
ice_devlink_flash_update and an ice_flash_pldm_image. It will make
additions like dry-run easier in the future.
* reducing time to read Option ROM version information.
* adding support for firmware activation via devlink reload, when
possible.
The major new work is the reload support, which allows activating firmware
immediately without a reboot when possible. Reload support only supports
firmware activation.
Jesse improves transmit code: utilizing newer netif_tx* API, adding some
prefetch calls, correcting expected conditions when calling ice_vsi_down(),
and utilizing __netdev_tx_sent_queue() call.

The wakeup and sleep commands need to be sent to the WILC chip only
when it is in power save mode (PSM, as controlled by "iw dev wlan0 set
power_save on/off"). The commands are relatively costly, so it pays
to skip them when possible.

This fix is similar to commit 77c91295ea ("wil6210: specify max. IE
length"). Without the max IE length set, wpa_supplicant cannot operate
using the nl80211 interface.
This patch is a workaround - the number 512 is taken from the wlcore
driver, but note that per Paul Fertser:
there's no correct number because the driver will ignore the data
passed in extra IEs.

Packet sockets may switch ring versions. Avoid misinterpreting state
between versions, whose fields share a union. rx_owner_map is only
allocated with a packet ring (pg_vec) and both are swapped together.
If pg_vec is NULL, meaning no packet ring was allocated, then neither
was rx_owner_map. And the field may be old state from a tpacket_v3.

Zero-initialize memory for new map's value in function nsim_bpf_map_alloc
since it may cause a potential kernel information leak issue, as follows:
1. nsim_bpf_map_alloc calls nsim_map_alloc_elem to allocate elements for
a new map.
2. nsim_map_alloc_elem uses kmalloc to allocate map's value, but doesn't
zero it.
3. A user application can use IOCTL BPF_MAP_LOOKUP_ELEM to get specific
element's information in the map.
4. The kernel function map_lookup_elem will call bpf_map_copy_value to get
the information allocated at step-2, then use copy_to_user to copy to the
user buffer.
This can only leak information for an array map.
