There is no guarantee that rmnet rx_handler is only fed with linear
skbs, but current rmnet implementation does not check that, leading
to crash in case of non linear skbs processed as linear ones.
Fix that by ensuring skb linearization before processing.

packets even if they are not forwarded to the networking stack
(XDP_PASS) but if they are redirected (XDP_REDIRECT), dropped (XDP_DROP)
or sent back using the same interface (XDP_TX). This patch allows the

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of a flexible-array member in
struct ice_res_tracker, instead of a one-element array and use the
struct_size() helper to calculate the size for the allocations.
Also, notice that the code below suggests that, currently, two too many
bytes are being allocated with devm_kzalloc(), as the total number of
entries (pf->irq_tracker->num_entries) for pf->irq_tracker->list[] is
_vectors_ and sizeof(*pf->irq_tracker) also includes the size of the
one-element array _list_ in struct ice_res_tracker.
drivers/net/ethernet/intel/ice/ice_main.c:3511:
3511 /* populate SW interrupts pool with number of OS granted IRQs. */
3512 pf->num_avail_sw_msix = (u16)vectors;
3513 pf->irq_tracker->num_entries = (u16)vectors;
3514 pf->irq_tracker->end = pf->irq_tracker->num_entries;
With this change, the right amount of dynamic memory is now allocated
because, contrary to one-element arrays which occupy at least as much
space as a single object of the type, flexible-array members don't
occupy such space in the containing structure.

Just as we recently added support for other stored firmware flash
versions, support display of the stored UNDI Option ROM version via
devlink info.
To do this, we need to introduce a new ice_get_inactive_orom_ver
function. This is a little trickier than with other flash versions. The
Option ROM version data was being read from a special "Boot
Configuration" block of the NVM Preserved Field Area. This block only
contains the *active* Option ROM version data. It is populated when the
device firmware finishes updating the Option ROM.
This method is ineffective at reading the stored Option ROM version
data. Instead of reading from this section of the flash, replace this
version extraction with one which locates the Combo Version information
from within the Option ROM binary.
This data is stored within the Option ROM at a 512 byte offset, in
a simple structured format. The structure uses a simple modulo 256
checksum for integrity verification. Scan through the Option ROM to
locate the CIVD data section, and extract the Combo Version.
Refactor ice_get_orom_ver_info so that it takes the bank select
enumeration parameter. Use this to implement ice_get_inactive_orom_ver.
Although all ice devices have a Boot Configuration block in the NVM PFA,
not all devices have a valid Option ROM. In this case, the old
ice_get_orom_ver_info would "succeed" but report a version of all
zeros. The new implementation would fail to locate the $CIV section in
the Option ROM and report an error. Thus, we must ensure that
ice_init_nvm does not fail if ice_get_orom_ver_info fails.
Use the new ice_get_inactive_orom_ver to allow reporting the Option ROM
versions for a pending update via devlink info.

Add a function to read the inactive netlist bank for version
information. To support this, refactor how we read the netlist version
data. Instead of using the firmware AQ interface with a module ID, read
from the flash as a flat NVM, using ice_read_flash_module.
This change requires a slight adjustment to the offset values used, as
reading from the flat NVM includes the type field (which was stripped by
firmware previously). Cleanup the macro names and move them to
ice_type.h. For clarity in how we calculate the offsets and so that
programmers can easily map the offset value to the data sheet, use
a wrapper macro to account for the offset adjustments.
Use the newly added ice_get_inactive_netlist_ver function to extract the
version data from the pending netlist module update. Add the stored
variants of "fw.netlist", and "fw.netlist.build" to the info version map
array.
With this change, we now report the "fw.netlist" and "fw.netlist.build"
versions into the stored section of the devlink info report. As with the
main NVM module versions, if there is no pending update, we report the
currently active values as stored.

The devlink info interface supports drivers reporting "stored" versions.
These versions indicate the version of an update that has been
downloaded to the device, but is not yet active.
The code for extracting the NVM version recently changed to enable
support for reading from either the active or the inactive bank. Use
this to implement ice_get_inactive_nvm_ver, which will read the NVM
version data from the inactive section of flash.
When reporting the versions via devlink info, first read the device
capabilities. Determine if there is a pending flash update, and if so,
extract relevant version information from the inactive flash. Store
these within the info context structure.
When reporting "stored" firmware versions, devlink documentation
indicates that we ought to always report a stored value, even if there
is no pending update. In this common case, the stored version should
match the running version. This means that each stored version should by
default fallback to the same value as reported by the running handler.
To support this, modify the version structure to have both a "getter"
and a "fallback". Modify the control loop so that it will use the
"fallback" function if the "getter" function does not report a version.
To report versions for which we can read the stored value, use a new
"stored()" macro. This macro will insert two entries into the version
list. The first entry is the traditional running version. The second is
the stored version, implemented with a fallback to the active version.
This is a little tricky, but reduces the overall duplication of elements
in the entry list, and ensures that running and stored values remain
consistent.
To avoid some duplication, add a combined() macro that will insert both
the running and stored versions into the version entry list.
Using this new support, add pending version reporter functions for
"fw.psid.api" and "fw.bundle_id". This enables reporting the stored
values for some of versions in the NVM module of the flash.
Reporting management versions is not implemented by this patch. The
active management version is reported to the driver via the AdminQ
mailbox during load. Although the version must be in the firmware binary
somewhere, accessing this from the inactive firmware is not trivial and
has not been implemented in this change.
Future changes will introduce support for reading the UNDI Option ROM
version and the version associated with the Netlist module.

When reading from the flash memory of the device, the ice driver has two
interfaces available to it. First, it can use a mediated interface via
firmware that allows specifying a module ID. This allows reading from
specific modules of the active flash bank.
The second interface available is to perform flat reads. This allows
complete access to the entire flash. However, using it requires the
software to handle calculating module location and interpret pointer
addresses.
While most data required is accessible through the convenient first
interface, certain flash contents are not. This includes the CSS header
information associated with the Option ROM and NVM banks, as well as any
access to the "inactive" banks used as scratch space for performing
flash updates.
In order to access all of the relevant flash contents, software must use
the flat reads. Rather than forcing all flows to perform flat read
calculations, introduce a new abstraction for reading from the flash:
ice_read_flash_module. This function provides an abstraction for reading
from either the active or inactive flash bank at the requested module.
This interface is very similar to the abstraction provided via firmware,
but allows access to additional modules, as well as providing
a mechanism to request access to both flash banks.
At first glance, it might make sense for this abstraction to allow
specifying precisely which bank (1st or 2nd) the caller wishes to read.
This is simpler to implement but more difficult to use. In practice,
most callers only know whether they want the active bank, or the
inactive bank. Rather than force callers to determine for themselves
which bank to read from, implement ice_read_flash_module in terms of
"active" vs "inactive". This significantly simplifies the implementation
at the caller level and is a more useful abstraction over the flash
contents.
Make use of this new interface to refactor reading of the main NVM
version information. Instead of using the firmware's mediated ShadowRAM
function, use the ice_read_flash_module abstraction.
To do this, notice that most reads of the NVM are going to be in 2-byte
word chunks. To simplify using ice_read_flash_module for this case,
ice_read_nvm_module is introduced. This is a simple wrapper around
ice_read_flash_module which takes the correct pointer address for the
NVM bank, and forces the 2-byte word format onto the caller.
When reading the NVM versions, some fields are read from the Shadow RAM.
The Shadow RAM is the first 64KB of flash memory, and is populated
during device load. Most fields are copied from a section within the
active NVM bank. In order to read this data from both the active and
inactive NVM banks, we need to read not from the first 64KB of flash,
but instead from the correct offset into the NVM bank. Introduce
ice_read_nvm_sr_copy for this purpose. This function wraps around
ice_read_nvm_module and has the same interface as the ice_read_sr_word,
with the exception of allowing the caller to specify whether to read the
active or inactive flash bank.
With this change, it is now trivial to refactor ice_get_nvm_ver_info to
read using the software mediated ice_read_flash_module interface instead
of relying on the firmware mediated interface. This will be used in the
following change to implement support for stored versions in the devlink
info report.
Additionally, the overall ice_read_flash_module interface will be used
and extended to support all three major flash banks, and additionally to
support reading the flash image security revision information.

The ice flash contains two copies of each of the NVM, Option ROM, and
Netlist modules. Each bank has a pointer word and a size word. In order
to correctly read from the active flash bank, the driver must calculate
the offset manually.
During NVM initialization, read the Shadow RAM control word and
determine which bank is active for each NVM module. Additionally, cache
the size and pointer values for use in calculating the correct offset.

The ice driver uses an array of structures which link an info name with
a function that formats the associated version data into a string.
All existing format functions simply format already captured static data
from the driver hw structure. Future changes will introduce format
functions for reporting the versions of flash sections stored but not
yet applied. This type of version data is not stored as a member of the
hw structure. This is because (a) it might not yet exist in the case
there is no pending flash update, and (b) even if it does, it might
change such as if an update is canceled or replaced by a new update
before finalizing.
We could simply have each format function gather its own data upon being
called. However, in some cases the raw binary version data is
a combination of multiple different reported fields. Additionally, the
current interface doesn't have a way for the function to indicate that
the version doesn't exist.
Refactor this function interface to take a new ice_info_ctx structure
instead of the buffer pointer and length. This context structure allows
for future extensions to pre-gather version data that is stored within
the context struct instead of the hw struct.
Allocate this context structure initially at the start of
ice_devlink_info_get. We use dynamic allocation instead of a local stack
variable in order to avoid using too much kernel stack once we extend it
with additional data structures.
Modify the main loop that drives the info reporting so that the version
buffer string is always cleared between each format. Explicitly check
that the format function actually filled in a version string of non-zero
length. If the string is not provided, simply skip this version without
reporting an error. This allows for introducing format functions of
versions which may or may not be present, such as the version of
a pending update that has not yet been activated.

The ice_nvm_info structure has become somewhat of a dumping ground for
all of the fields related to flash version. It holds the NVM version and
EETRACK id, the OptionROM info structure, the flash size, the ShadowRAM
size, and more.
A future change is going to add the ability to read the NVM version and
EETRACK ID from the inactive NVM bank. To make this simpler, it is
useful to have these NVM version info fields extracted to their own
structure.
Rename ice_nvm_info into ice_flash_info, and create a separate
ice_nvm_info structure that will contain the eetrack and NVM map
version. Move the netlist_ver structure into ice_flash_info and rename it
ice_netlist_info for consistency.
Modify the static ice_get_orom_ver_info to take the option rom structure
as a pointer. This makes it more obvious what portion of the hw struct
is being modified. Do the same for ice_get_netlist_ver_info.
Introduce a new ice_get_nvm_ver_info function, which will be similar to
ice_get_orom_ver_info and ice_get_netlist_ver_info, used to keep the NVM
version extraction code co-located.

We were starting the early time-point too late in non-unified
firmwares. Unlike with unified firmwares, we were starting it only
after reading the NVM, so errors in the NVM read phase were not
logged.
Solve this by moving the time-point to the same place as we do with
unified firmwares, i.e. just before we go into the wait-alive code.

In struct iwl_tx_cmd, there's no risk (as Arnd implied) that we
might access this as an array, as it's really not an array and
cannot be - there's only a single 802.11 header per frame. The
only reason for this member is for being able to access it a
bit more nicely.
On the other hand, this structure is used as a sub-struct in a
few places, and then some compilers (e.g. clang with certain
options) complain as you shouldn't have structs with variable-
length fields embedded in other structs.

If the firmware has support, then advertise it to the stack and
send the key down. Since we re-check the protection in the host
anyway, we don't really need to do anything on RX except that we
should drop frames that the firmware _knows_ are replay errors,
since beacon filtering might otherwise result in replays being
possible.

When we check the length, we only check that the advertised
data length fits into the data we have, but currently not
that it actually matches correctly.
This should be harmless, but if the first two bytes are zero,
then the iwl_rx_packet_payload_len() ends up negative, and
that might later cause issues if unsigned variables are used,
as this is not something that's normally expected.
Change the validation here to precisely validate the lengths
match, to avoid such issues.

In roaming flows and during reassociation, its possible that data frames
such as EAPOLs for 4 way handshake/ 802.1x authentication are initially set
to higher MCS rate. Though these are pruned down to a lower legacy rate
before sending to the FW, driver also emits a kernel warning - intended for
non-data frames. Add checks to avoid such warnings for data frames, while
also enhancing the debug data printed.
