support for signing modules using elliptic curve keys because there's
a new series for that that fixes a few confising things - Linus ]
* tag 'tpmdd-next-v5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd:
tpm: Replace WARN_ONCE() with dev_err_once() in tpm_tis_status()
tpm_tis: Use DEFINE_RES_MEM() to simplify code
tpm: fix some doc warnings in tpm1-cmd.c
tpm_tis_spi: add missing SPI device ID entries

char: tpm: move to use request_irq by IRQF_NO_AUTOEN flag
tpm_tis_spi: set default probe function if device id not match

Mostly a restructure of the kcs_bmc driver to make it easier to
use with different types of devices, and just to clean things up and
improve things.
Also some bug fixes for the kcs_bmc driver.
One fix to the IPMI watchdog to stop the timer when the action is none.

Instead, introduce TPM_TIS_INVALID_STATUS bitflag and use it to trigger
once the error reporting per chip. In addition, print out the value of
TPM_STS for improved forensics.

The SPI core always reports a "MODALIAS=spi:<foo>", even if the device was

for example has a node with a compatible "infineon,slb9670" string.
In that case kmod will expect a "MODALIAS=of:N*T*Cinfineon,slb9670" uevent

While running a TPM2_CC_VERIFY_SIGNATURE operation with RSA 3072-bit
keys the TPM driver fails with the following error:
"kernel: [ 2416.187522] tpm tpm0: Operation Timed out"
Since the TPM PC Client specification does not specify a number for
verify signature operation timeout, and the duration of
TPM2_CC_VERIFY_SIGNATURE with RSA 3072-bit keys exceeds the current timeout
of TPM_LONG (2 seconds), it is preferable to pick the longest timeout
possible.
Therefore, set the duration for TPM2_CC_VERIFY_SIGNATUE to TPM_LONG_LONG
(5 minutes).

Some Aspeed KCS devices can derive the status register address from the
address of the data register. As such, the address of the status
register can be implicit in the configuration if desired. On the other
hand, sometimes address schemes might be requested that are incompatible
with the default addressing scheme. Allow these requests where possible
if the devicetree specifies the status register address.

Add a mechanism for controlling whether the client associated with a
KCS device will receive Input Buffer Full (IBF) and Output Buffer Empty
(OBE) events. This enables an abstract implementation of poll() for KCS
devices.
A wart in the implementation is that the ASPEED KCS devices don't
support an OBE interrupt for the BMC. Instead we pretend it has one by
polling the status register waiting for the Output Buffer Full (OBF) bit
to clear, and generating an event when OBE is observed.

Move all client-private data out of `struct kcs_bmc` into the KCS client
implementation.
With this change the KCS BMC core code now only concerns itself with
abstract `struct kcs_bmc` and `struct kcs_bmc_client` types, achieving
expected separation of concerns. Further, the change clears the path for
implementation of alternative userspace interfaces.
The chardev data-structures are rearranged in the same manner applied to
the KCS device driver data-structures in an earlier patch - `struct
kcs_bmc_client` is embedded in the client's private data and we exploit
container_of() to translate as required.
Finally, now that it is free of client data, `struct kcs_bmc` is renamed
to `struct kcs_bmc_device` to contrast `struct kcs_bmc_client`.

Make the KCS device drivers responsible for allocating their own memory.
Until now the private data for the device driver was allocated internal
to the private data for the chardev interface. This coupling required
the slightly awkward API of passing through the struct size for the
driver private data to the chardev constructor, and then retrieving a
pointer to the driver private data from the allocated chardev memory.
In addition to being awkward, the arrangement prevents the
implementation of alternative userspace interfaces as the device driver
private data is not independent.
Peel a layer off the onion and turn the data-structures inside out by
exploiting container_of() and embedding `struct kcs_device` in the
driver private data.

When an IPMI watchdog timer is being stopped in ipmi_close() or
ipmi_ioctl(WDIOS_DISABLECARD), the current watchdog action is updated to
WDOG_TIMEOUT_NONE and _ipmi_set_timeout(IPMI_SET_TIMEOUT_NO_HB) is called
to install this action. The latter function ends up invoking
__ipmi_set_timeout() which makes the actual 'Set Watchdog Timer' IPMI
request.
For IPMI 1.0, this operation results in fully stopping the watchdog timer.
For IPMI >= 1.5, function __ipmi_set_timeout() always specifies the "don't
stop" flag in the prepared 'Set Watchdog Timer' IPMI request. This causes
that the watchdog timer has its action correctly updated to 'none' but the
timer continues to run. A problem is that IPMI firmware can then still log
an expiration event when the configured timeout is reached, which is
unexpected because the watchdog timer was requested to be stopped.
The patch fixes this problem by not setting the "don't stop" flag in
__ipmi_set_timeout() when the current action is WDOG_TIMEOUT_NONE which
results in stopping the watchdog timer. This makes the behaviour for
IPMI >= 1.5 consistent with IPMI 1.0. It also matches the logic in
__ipmi_heartbeat() which does not allow to reset the watchdog if the
current action is WDOG_TIMEOUT_NONE as that would start the timer.

The function hpet_resources() calls ioremap() two times, but in both
cases it does not check if ioremap() returned a null pointer. Fix this
by adding null pointer checks and returning an appropriate error.

This reverts commit 13bd14a41ce3105d5b1f3cd8b4d1e249d17b6d9b.
Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.
Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.
While this is technically correct, it is only fixing ONE of these errors
in this function, so the patch is not fully correct. I'll leave this
revert and provide a fix for this later that resolves this same
"problem" everywhere in this function.

If the total number of commands queried through TPM2_CAP_COMMANDS is
different from that queried through TPM2_CC_GET_CAPABILITY, it indicates
an unknown error. In this case, an appropriate error code -EFAULT should
be returned. However, we currently do not explicitly assign this error
code to 'rc'. As a result, 0 was incorrectly returned.

Patch series "drivers/char: remove /dev/kmem for good".
Exploring /dev/kmem and /dev/mem in the context of memory hot(un)plug and
memory ballooning, I started questioning the existence of /dev/kmem.
Comparing it with the /proc/kcore implementation, it does not seem to be
able to deal with things like
a) Pages unmapped from the direct mapping (e.g., to be used by secretmem)
-> kern_addr_valid(). virt_addr_valid() is not sufficient.
b) Special cases like gart aperture memory that is not to be touched
-> mem_pfn_is_ram()
Unless I am missing something, it's at least broken in some cases and might
fault/crash the machine.
Looks like its existence has been questioned before in 2005 and 2010 [1],
after ~11 additional years, it might make sense to revive the discussion.
CONFIG_DEVKMEM is only enabled in a single defconfig (on purpose or by
mistake?). All distributions disable it: in Ubuntu it has been disabled
for more than 10 years, in Debian since 2.6.31, in Fedora at least
starting with FC3, in RHEL starting with RHEL4, in SUSE starting from
15sp2, and OpenSUSE has it disabled as well.
1) /dev/kmem was popular for rootkits [2] before it got disabled
basically everywhere. Ubuntu documents [3] "There is no modern user of
/dev/kmem any more beyond attackers using it to load kernel rootkits.".
RHEL documents in a BZ [5] "it served no practical purpose other than to
serve as a potential security problem or to enable binary module drivers
to access structures/functions they shouldn't be touching"
2) /proc/kcore is a decent interface to have a controlled way to read
kernel memory for debugging puposes. (will need some extensions to
deal with memory offlining/unplug, memory ballooning, and poisoned
pages, though)
3) It might be useful for corner case debugging [1]. KDB/KGDB might be a
better fit, especially, to write random memory; harder to shoot
yourself into the foot.
4) "Kernel Memory Editor" [4] hasn't seen any updates since 2000 and seems
to be incompatible with 64bit [1]. For educational purposes,
/proc/kcore might be used to monitor value updates -- or older
kernels can be used.
5) It's broken on arm64, and therefore, completely disabled there.
Looks like it's essentially unused and has been replaced by better
suited interfaces for individual tasks (/proc/kcore, KDB/KGDB). Let's
just remove it.

Here is the big set of tty and serial driver updates for 5.13-rc1.
Actually busy this release, with a number of cleanups happening:
- much needed core tty cleanups by Jiri Slaby
- removal of unused and orphaned old-style serial drivers. If
anyone shows up with this hardware, it is trivial to restore
these but we really do not think they are in use anymore.
- fixes and cleanups from Johan Hovold on a number of termios
setting corner cases that loads of drivers got wrong as well
as removing unneeded code due to tty core changes from long
ago that were never propagated out to the drivers
- loads of platform-specific serial port driver updates and
fixes
- coding style cleanups and other small fixes and updates all
over the tty/serial tree.
All of these have been in linux-next for a while now with no reported
issues.
