A problem about modprobe ingenic-drm failed is triggered with the following
log given:
[ 303.561088] Error: Driver 'ingenic-ipu' is already registered, aborting...
modprobe: ERROR: could not insert 'ingenic_drm': Device or resource busy
The reason is that ingenic_drm_init() returns platform_driver_register()
directly without checking its return value, if platform_driver_register()
failed, it returns without unregistering ingenic_ipu_driver_ptr, resulting
the ingenic-drm can never be installed later.
A simple call graph is shown as below:

platform_driver_register()
driver_register()

# return without unregister ingenic_ipu_driver_ptr
Fixing this problem by checking the return value of
platform_driver_register() and do platform_unregister_drivers() if

The RTL8192CU and a version of RTL8723AU apparently don't have the
ability to adjust the oscillator, so this doesn't apply to them.
This also doesn't apply to the wifi + bluetooth combo chips (RTL8723AU

bluetooth is disabled, and determining that looked complicated.

The <linux/bcma/bcma_driver_chipcommon.h> is including the legacy
header <linux/gpio.h> to obtain struct gpio_chip. Instead, include
<linux/gpio/driver.h> where this struct is defined.
It turns out that the brcm80211 brcmsmac depends on this to
bring in the symbol gpio_is_valid().
The driver looks up the BCMA parent GPIO driver and checks that
this succeeds, but then it goes on to use the deprecated GPIO
call gpio_is_valid() to check the consistency of the .base
member of the BCMA GPIO struct. The whole check can be dropped
because the bcma_gpio is initialized in the declarations:
struct gpio_chip *bcma_gpio = &cc_drv->gpio;
And this can never be NULL.

This patch fixes a shift-out-of-bounds in brcmfmac that occurs in
BIT(chiprev) when a 'chiprev' provided by the device is too large.
It should also not be equal to or greater than BITS_PER_TYPE(u32)
as we do bitwise AND with a u32 variable and BIT(chiprev). The patch
adds a check that makes the function return NULL if that is the case.
Note that the NULL case is later handled by the bus-specific caller,
brcmf_usb_probe_cb() or brcmf_usb_reset_resume(), for example.
Found by a modified version of syzkaller.

macsec: offload-related fixes
I'm working on a dummy offload for macsec on netdevsim. It just has a
small SecY and RXSC table so I can trigger failures easily on the
ndo_* side. It has exposed a couple of issues.
The first patch is a revert of commit c850240b6c ("net: macsec:
report real_dev features when HW offloading is enabled"). That commit
tried to improve the performance of macsec offload by taking advantage
of some of the NIC's features, but in doing so, broke macsec offload
when the lower device supports both macsec and ipsec offload, as the
ipsec offload feature flags were copied from the real device. Since
the macsec device doesn't provide xdo_* ops, the XFRM core rejects the
registration of the new macsec device in xfrm_api_check.
I'm working on re-adding those feature flags when offload is
available, but I haven't fully solved that yet. I think it would be
safer to do that second part in net-next considering how complex
feature interactions tend to be.
v2:
- better describe the issue introduced by commit c850240b6c (Leon
Romanovsky)
- patch #3: drop unnecessary !! (Leon Romanovsky)
v3:

macsec_is_configured incorrectly uses secy->n_rx_sc to check if some
RXSCs exist. secy->n_rx_sc only counts the number of active RXSCs, but
there can also be inactive SCs as well, which may be stored in the
driver (in case we're disabling offloading), or would have to be
pushed to the device (in case we're trying to enable offloading).
As long as RXSCs active on creation and never turned off, the issue is
not visible.

secy->n_rx_sc is supposed to be the number of _active_ rxsc's within a
secy. This is then used by macsec_send_sci to help decide if we should
add the SCI to the header or not.
This logic is currently broken when we create a new RXSC and turn it
off at creation, as create_rx_sc always sets ->active to true (and
immediately uses that to increment n_rx_sc), and only later
macsec_add_rxsc sets rx_sc->active.

net: ipa: support more endpoints
This series adds support for more than 32 IPA endpoints. To do
this, five registers whose bits represent endpoint state are
replicated as needed to represent endpoints beyond 32. For existing
platforms, the number of endpoints is never greater than 32, so
there is just one of each register. IPA v5.0+ supports more than
that though; these changes prepare the code for that.
Beyond that, the IPA fields that represent endpoints in a 32-bit
bitmask are updated to support an arbitrary number of these endpoint
registers. (There is one exception, explained in patch 7.)
The first two patches are some sort of unrelated cleanups, making
use of a helper function introduced recently.
The third and fourth use parameterized functions to determine the
register offset for registers that represent endpoints.
The last five convert fields representing endpoints to allow more
than 32 endpoints to be represented.
Since v1, I have implemented Jakub's suggestions:
- Don't print a message on (bitmap) memory allocation failure
- Do not do "mass null checks" when allocating bitmaps
- Rework some code to ensure error path is sane

Prior to IPA v5.0, there could be no more than 32 endpoints.
A filter table begins with a bitmap indicating which endpoints have
a filter defined. That bitmap is currently assumed to fit in a
32-bit value.
Starting with IPA v5.0, more than 32 endpoints are supported, so
it's conceivable that a TX endpoint has an ID that exceeds 32.
Increase the size of the field representing endpoints that support
filtering to 64 bits. Rename the bitmap field "filtered".
Unlike other similar fields, we do not use an (arbitrarily long)
Linux bitmap for this purpose. The reason is that if a filter table
ever *did* need to support more than 64 TX endpoints, its format
would change in ways we can't anticipate.
Have ipa_endpoint_init() return a negative errno rather than a mask
that indicates which endpoints support filtering, and have that
function assign the "filtered" field directly.

IPA v5.0 supports more than 32 endpoints, so we will be unable to
represent endpoints defined in the configuration data with a 32-bit
value. To prepare for that, convert the field in the IPA structure
representing defined endpoints to be a Linux bitmap.
Convert loops based on that field into for_each_set_bit() calls over
the new bitmap. Note that the loop in ipa_endpoint_config() still
assumes there are 32 or fewer endpoints (when comparing against the
available endpoint bit mask); that assumption goes away in the next
patch.

Starting with IPA v5.0, a single IPA instance can have more than 32
endpoints defined. To handle this, each register that holds a
bitmap of IPA endpoints is replicated as needed to represent the
available endpoints.
To prepare for this, registers that represent endpoint IDs in a bit
mask will be defined to have a parameter, with a stride value of 4
bytes. The first 32 endpoints are represented in the first 32-bit
register, then the next (up to) 32 endpoints at an offset 4 bytes
higher. When accessing such a register, the endpoint ID divided
by 32 determines the offset, and the endpoint ID modulo 32 defines
the endpoint's bit position within the register.
The first two registers we'll update for this are STATE_AGGR_ACTIVE
and AGGR_FORCE_CLOSE.
Until more than 32 endpoints are supported, this change has no
practical effect.

Similar to the previous commit, pass flags rather than a memory
region ID to ipa_table_reset_add(), and there use ipa_table_mem() to
look up the memory region affected based on those flags.
Currently all eight of these table memory regions are assumed to
exist, because they all have canaries within them. Stop assuming
that will always be the case, and in ipa_table_reset_add() allow
these memory regions to be non-existent.

Recently ipa_table_mem() was added as a way to look up one of 8
possible memory regions by indicating whether it was a filter or
route table, hashed or not, and IPv6 or not.
We can simplify the interface to ipa_table_init_add() by passing two
flags to it instead of the opcode and both hashed and non-hashed
memory region IDs. The "filter" and "ipv6" flags are sufficient to
determine the opcode to use, and with ipa_table_mem() can look up
the correct memory region as well.
It's possible to not have hashed tables, but we already verify the
number of entries in a filter or routing table is nonzero. Stop
assuming a hashed table entry exists in ipa_table_init_add().

In some conditions, background processes in udpgro don't have enough
time to set up the sockets. When foreground processes start, this
results in the test failing with "./udpgso_bench_tx: sendmsg: Connection
refused". For instance, this happens from time to time on a Qualcomm
SA8540P SoC running CentOS Stream 9.
To fix this, increase the time given to background processes to
complete the startup before foreground processes start.

implementation of the Crypto Extension acceleration of the SM4 algorithm:
Extract the macro optimized by SM4 Crypto Extension for reuse in the
subsequent optimization of CCM/GCM modes.
Encryption in CBC and CFB modes processes four blocks at a time instead of
one, allowing the ld1 instruction to load 64 bytes of data at a time, which
will reduces unnecessary memory accesses.
CBC/CFB/CTR makes full use of free registers to reduce redundant memory
accesses, and rearranges some instructions to improve out-of-order execution
capabilities.
