(cherry picked from commit 2888f960d0)
To satisfy the FIPS 140-3 "service indicators" requirement, add a
function which checks whether the given algorithm is "approved" or not.
Note that this function is a bit different from the module's other APIs
in that it is an exported symbol rather than a registration-based API.
This avoids needing to make kernel/KMI changes, so I think we should do
it this way if possible, given that it's unlikely this function will be
used in practice outside of the lab test. Built-in code can still call
this function via symbol_get() if it really wants to.

The lab has confirmed that it is actually fine for users to keep using
non-FIPS code after the module has loaded if they were already using it
beforehand. So remove the code that tried to prevent this by updating
live algorithms in-place. Similarly, remove the call to
synchronize_rcu_tasks() which no longer has any purpose.
We still need to move the live algorithms to a private list, so keep
doing that. Keep appending "+orig" to cra_name as well, and start doing
the same for cra_driver_name too.

(cherry picked from commit 54aecb72db)
As per the new guidance from the lab, the module must block crypto
operations until the tests have completed. It's unclear what this means
exactly (given that technically this is impossible), but let's make some
changes that should be enough to comply with the requirement's intent.
First, register the library functions and update the live algorithms
after the tests rather than before the tests. This is a trivial change.
Much more problematic is the fact that the algorithms are registered
with the kernel's crypto framework before the tests run, as the tests
depend on the framework. Unfortunately, the lab believes that the
kernel isn't allowed to enforce the ordering here; the module itself
must. Moreover, trying to solve this by copying the crypto API
framework into the module proved to be heavily problematic.
Thus, implement an alternate solution: make the module override the tfm
initialization function of every algorithm it registers, so that it can
wait for the tests to complete before allowing the use of any algorithm.
This is sufficient if the user makes a supported sequence of API calls.

(cherry picked from commit 02e48f383b)
Instead of having a special case in the core kernel's module loader that
treats a module called 'fips140.ko' in a special way, use a host tool to
tweak the ELF metadata of this module so that the RELA data is preserved
and accessible to the module init code.
This is done in the following way:
- each RELA section that we care about (the ones for .text and .rodata
at the moment) is copied into a new section called .init.rela.<name>
with the SHF_ALLOC attribute, so that the module loader will copy it
into __init memory at load time;
- for each such section, an offset/count tuple is added as a global
variable to the module;
- the count field of those tuples is populated directly by the host tool
based on the actual size of the RELA section in question;
- the offset field is decorated with a place-relative relocation against
the start of the copied RELA section via a weak symbol reference,
which causes an entry to be emitted into the ELF symbol table;
- these ELF symbol table entries are updated by the host tool and turned
into STT_SECTION type symbols with STB_GLOBAL linkage, carrying the
correct section index.
With these changes in place, the unmodified module loader will load all
required information into memory in a way that permits the module init
code to locate the relocations, and apply them in reverse.

(cherry picked from commit 502af6e349)
We currently only emit directives for handling the .text section into
the module linker script if both LTO and CFI are enabled, while for
other sections, we do this even if CFI is not enabled. This is
inconsistent at best, but as it also interferes with the assumption in
the fips140.ko module that the .text._start and .text._end input
sections are placed at the very start and end of the .text section,
which currently can only be relied upon if CFI is enabled.
So rearrange the #ifdef so that it only covers the .text.__cfi_check
input section. Note that aligning to page size is likely to be redundant
in any case, given that the .text section is laid out first, and module
allocations are page aligned to begin with, so making that part
unconditional is unlikely to make an observeable difference in the
output.

Unfortunately, the AES-GCM implementations won't actually be able to be

(cherry picked from commit fa5a44b364)
Test all implementations of each algorithm rather than just the highest
priority implementation. This aligns with the revised guidance we have
received from the lab.
We can still skip some tests in some cases, as per the FIPS 140-2
Implementation Guidance document. See the comments for details.
To align with the new scope of the tests, the fips140.broken_alg module
parameter now must specify an implementation (e.g. "sha256-ce") rather
than an algorithm (e.g. "sha256").
No change to the DRBG tests is required, as it turns out the module only
includes HMAC_DRBG. However, clarify the comment about the DRBG tests.
On a Pixel device, this increases the running time of the fips140 tests
from 0.5ms to 3.1 ms (very roughly; there's a lot of variation). This
is still very fast, so it isn't expected to be a problem.

The __UNIQUE_ID() macro causes problems as it turns out to not be
deterministic across different compiler runs as it relies on the
__COUNTER__ macro which could have been used on other .h files previous
to this .h file being included.
This shows up specifically when building with "LTO=thin" vs. "LTO=full"
as different build paths seem to be triggered.
As the structure name isn't really needed at all here, we were just
including it for older compilers that could not handle anonymous
structures in a union, just drop the whole thing which resolves the abi
naming issue.

Commit f1a0a376ca ("sched/core: Initialize the idle task with

idle_thread_get(). This was the sole call-path on hotplug that resets
the Shadow Call Stack (scs) Stack Pointer (sp).
Not resetting the scs-sp leads to scs overflow after enough hotplug
cycles. Therefore add an explicit scs_task_reset() to the hotplug code
to make sure the scs-sp does get reset on hotplug.

Some functions may dynamically enable and disable their endpoints
regularly throughout their operation, particularly when Set Interface
is employed to switch between Alternate Settings. For instance the
UAC2 function has its respective endpoints for playback & capture
associated with AltSetting 1, in which case those endpoints would not
get enabled until the host activates the AltSetting. And they
conversely become disabled when the interfaces' AltSetting 0 is
chosen.
With the DWC3 FIFO resizing algorithm recently added, every
usb_ep_enable() call results in a call to resize that EP's TXFIFO,
but if the same endpoint is enabled again and again, this incorrectly
leads to FIFO RAM allocation exhaustion as the mechanism did not
account for the possibility that endpoints can be re-enabled many
times.

If so, bail out of dwc3_gadget_resize_tx_fifos() to avoid the

repeatedly. This flag is retained across multiple ep_disable() and
ep_enable() calls and is cleared when GTXFIFOSIZn is reset in
dwc3_gadget_clear_tx_fifos() upon receiving the next Set Config.
