"New features:
- Cr50 I2C TPM driver
- sysfs exports of PCR registers in TPM 2.0 chips
Bug fixes:
- bug fixes for tpm_tis driver, which had a racy wait for hardware
state change to be ready to send a command to the TPM chip. The bug
has existed already since 2006, but has only made itself known in
recent past. This is the same as the "last time" :-)
- Otherwise there's bunch of fixes for not as alarming regressions. I
think the list is about the same as last time, except I added fixes
for some disjoint bugs in trusted keys that I found some time ago"

KEYS: trusted: Reserve TPM for seal and unseal operations
When TPM 2.0 trusted keys code was moved to the trusted keys subsystem,
the operations were unwrapped from tpm_try_get_ops() and tpm_put_ops(),
which are used to take temporarily the ownership of the TPM chip. The
ownership is only taken inside tpm_send(), but this is not sufficient,
as in the key load TPM2_CC_LOAD, TPM2_CC_UNSEAL and TPM2_FLUSH_CONTEXT
need to be done as a one single atom.
Take the TPM chip ownership before sending anything with
tpm_try_get_ops() and tpm_put_ops(), and use tpm_transmit_cmd() to send
TPM commands instead of tpm_send(), reverting back to the old behaviour.

tpm: add sysfs exports for all banks of PCR registers
Create sysfs per hash groups with 24 PCR files in them one group, named pcr-<hash>, for each agile hash of the TPM. The files are plugged in to a PCR read function which is TPM version agnostic, so this works also for TPM 1.2 but the hash is only sha1 in that case. Note: the macros used to create the hashes emit spurious checkpatch warnings. Do not try to "fix" them as checkpatch recommends, otherwise they'll break.

char: tpm: add i2c driver for cr50
Add TPM 2.0 compatible I2C interface for chips with cr50 firmware. The firmware running on the currently supported H1 MCU requires a special driver to handle its specific protocol, and this makes it unsuitable to use tpm_tis_core_* and instead it must implement the underlying TPM protocol similar to the other I2C TPM drivers. - All 4 bytes of status register must be read/written at once. - FIFO and burst count is limited to 63 and must be drained by AP. - Provides an interrupt to indicate when read response data is ready and when the TPM is finished processing write data. This driver is based on the existing infineon I2C TPM driver, which most closely matches the cr50 i2c protocol behavior.

tpm_tis: Clean up locality release
The current release locality code seems to be based on the
misunderstanding that the TPM interrupts when a locality is released:
it doesn't, only when the locality is acquired.
Furthermore, there seems to be no point in waiting for the locality to
be released. All it does is penalize the last TPM user. However, if
there's no next TPM user, this is a pointless wait and if there is a
next TPM user, they'll pay the penalty waiting for the new locality
(or possibly not if it's the same as the old locality).
Fix the code by making release_locality as simple write to release
with no waiting for completion.

tpm_tis: Fix check_locality for correct locality acquisition
The TPM TIS specification says the TPM signals the acquisition of locality
when the TMP_ACCESS_REQUEST_USE bit goes to one *and* the
TPM_ACCESS_REQUEST_USE bit goes to zero. Currently we only check the
former not the latter, so check both. Adding the check on
TPM_ACCESS_REQUEST_USE should fix the case where the locality is
re-requested before the TPM has released it. In this case the locality may
get released briefly before it is reacquired, which causes all sorts of
problems. However, with the added check, TPM_ACCESS_REQUEST_USE should
remain 1 until the second request for the locality is granted.

random: avoid arch_get_random_seed_long() when collecting IRQ randomness
When reseeding the CRNG periodically, arch_get_random_seed_long() is called to obtain entropy from an architecture specific source if one is implemented. In most cases, these are special instructions, but in some cases, such as on ARM, we may want to back this using firmware calls, which are considerably more expensive. Another call to arch_get_random_seed_long() exists in the CRNG driver, in add_interrupt_randomness(), which collects entropy by capturing inter-interrupt timing and relying on interrupt jitter to provide random bits. This is done by keeping a per-CPU state, and mixing in the IRQ number, the cycle counter and the return address every time an interrupt is taken, and mixing this per-CPU state into the entropy pool every 64 invocations, or at least once per second. The entropy that is gathered this way is credited as 1 bit of entropy. Every time this happens, arch_get_random_seed_long() is invoked, and the result is mixed in as well, and also credited with 1 bit of entropy. This means that arch_get_random_seed_long() is called at least once per second on every CPU, which seems excessive, and doesn't really scale, especially in a virtualization scenario where CPUs may be oversubscribed: in cases where arch_get_random_seed_long() is backed by an instruction that actually goes back to a shared hardware entropy source (such as RNDRRS on ARM), we will end up hitting it hundreds of times per second. So let's drop the call to arch_get_random_seed_long() from add_interrupt_randomness(), and instead, rely on crng_reseed() to call the arch hook to get random seed material from the platform.

powerpc updates for 5.11
- Switch to the generic C VDSO, as well as some cleanups of our VDSO
setup/handling code.
- Support for KUAP (Kernel User Access Prevention) on systems using the hashed
page table MMU, using memory protection keys.
- Better handling of PowerVM SMT8 systems where all threads of a core do not
share an L2, allowing the scheduler to make better scheduling decisions.
- Further improvements to our machine check handling.
- Show registers when unwinding interrupt frames during stack traces.
- Improvements to our pseries (PowerVM) partition migration code.
- Several series from Christophe refactoring and cleaning up various parts of
the 32-bit code.
- Other smaller features, fixes & cleanups.

um: random: Register random as hwrng-core device
The UML random driver creates a dummy device under the guest,
/dev/hw_random. When this file is read from the guest, the driver
reads from the host machine's /dev/random, in-turn reading from
the host kernel's entropy pool. This entropy pool could have been
filled by a hardware random number generator or just the host
kernel's internal software entropy generator.
Currently the driver does not fill the guests kernel entropy pool,
this requires a userspace tool running inside the guest (like
rng-tools) to read from the dummy device provided by this driver,
which then would fill the guest's internal entropy pool.
This all seems quite pointless when we are already reading from an
entropy pool, so this patch aims to register the device as a hwrng
device using the hwrng-core framework. This not only improves and
cleans up the driver, but also fills the guest's entropy pool
without having to resort to using extra userspace tools in the guest.
This is typically a nuisance when booting a guest: the random pool
takes a long time (~200s) to build up enough entropy since the dummy
hwrng is not used to fill the guest's pool.
This port was originally attempted by Alexander Neville "dark" (in CC,
discussion in Link), but the conversation there stalled since the
handling of -EAGAIN errors were no removed and longer handled by the
driver. This patch attempts to use the existing method of error
handling but utilises the new hwrng core.
The issue can be noticed when booting a UML guest:
[ 2.560000] random: fast init done
[ 214.000000] random: crng init done
With the patch applied, filling the pool becomes a lot quicker:
[ 2.560000] random: fast init done
[ 12.000000] random: crng init done

powerpc/ps3: make system bus's remove and shutdown callbacks return void
The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. For the shutdown callback it's ps3_system_bus_shutdown() which ignores the return value. To simplify the quest to make struct device_driver::remove return void, let struct ps3_system_bus_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

hwrng: hisi - remove HiSilicon TRNG driver
Driver of HiSilicon true random number generator(TRNG) is removed from 'drivers/char/hw_random'. Both 'Kunpeng 920' and 'Kunpeng 930' chips have TRNG, however, PRNG is only supported by 'Kunpeng 930'. So, this driver is moved to 'drivers/crypto/hisilicon/trng/' in the next to enable the two's TRNG better.

crypto: sha - split sha.h into sha1.h and sha2.h
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

char/agp: Disable frontend without CONFIG_DRM_LEGACY
It's probably full of bugs ready for exploiting by userspace. And there's not going to be any userspace for this without any of the drm legacy drivers enabled too. So just couple it together. Note that the frontend is only the /dev/agp ioctl interface, which per Adam is only used by the i810 userspace drivers. All other drivers go through the drm bufmap agp handling abstraction apparently. v2: Augment commit message a bit from m-l feedback.

s390/trng: set quality to 1024
The s390-trng does provide 100% entropy. The quality value is supported to be between 1 and 1024 and not 1..1000. Use 1024 to make this driver the preferred one. If we ever have a better driver that has the same quality but is faster we can change this again when merging the new driver. No need to be conservative. This makes sure that the hw variant is preferred over things like virtio-rng, where the hypervisor has a potential to be misconfigured and thus should have a slightly lower confidence.

tpm: efi: Don't create binary_bios_measurements file for an empty log
Mimic the pre-existing ACPI and Device Tree event log behavior by not

In this situation, the bios_event_log pointer in the tpm_bios_log struct
was not NULL but was equal to the ZERO_SIZE_PTR (0x10) value. This was
due to the following kmemdup() in tpm_read_log_efi():
int tpm_read_log_efi(struct tpm_chip *chip)
{
...
/* malloc EventLog space */
log->bios_event_log = kmemdup(log_tbl->log, log_size, GFP_KERNEL);
if (!log->bios_event_log) {
ret = -ENOMEM;
goto out;
}
...
}
When log_size is zero, due to an empty event log from firmware,
ZERO_SIZE_PTR is returned from kmemdup(). Upon a read of the
binary_bios_measurements file, the tpm2_bios_measurements_start()
function does not perform a ZERO_OR_NULL_PTR() check on the
bios_event_log pointer before dereferencing it.
Rather than add a ZERO_OR_NULL_PTR() check in functions that make use of
the bios_event_log pointer, simply avoid creating the
binary_bios_measurements_file as is done in other event log retrieval
backends.
Explicitly ignore all of the events in the final event log when the main
event log is empty. The list of events in the final event log cannot be
accurately parsed without referring to the first event in the main event
log (the event log header) so the final event log is useless in such a
situation.

tpm_tis: Disable interrupts on ThinkPad T490s
There is a misconfiguration in the bios of the gpio pin used for the interrupt in the T490s. When interrupts are enabled in the tpm_tis driver code this results in an interrupt storm. This was initially reported when we attempted to enable the interrupt code in the tpm_tis driver, which previously wasn't setting a flag to enable it. Due to the reports of the interrupt storm that code was reverted and we went back to polling instead of using interrupts. Now that we know the T490s problem is a firmware issue, add code to check if the system is a T490s and disable interrupts if that is the case. This will allow us to enable interrupts for everyone else. If the user has a fixed bios they can force the enabling of interrupts with tpm_tis.interrupts=1 on the kernel command line.

random32: make prandom_u32() output unpredictable
Non-cryptographic PRNGs may have great statistical properties, but are usually trivially predictable to someone who knows the algorithm, given a small sample of their output. An LFSR like prandom_u32() is particularly simple, even if the sample is widely scattered bits. It turns out the network stack uses prandom_u32() for some things like random port numbers which it would prefer are *not* trivially predictable. Predictability led to a practical DNS spoofing attack. Oops. This patch replaces the LFSR with a homebrew cryptographic PRNG based on the SipHash round function, which is in turn seeded with 128 bits of strong random key. (The authors of SipHash have *not* been consulted about this abuse of their algorithm.) Speed is prioritized over security; attacks are rare, while performance is always wanted. Replacing all callers of prandom_u32() is the quick fix. Whether to reinstate a weaker PRNG for uses which can tolerate it is an open question. Commit |

"Not a major amount of change, the i915 trees got split into display
and gt trees to better facilitate higher level review, and there's a
major refactoring of i915 GEM locking to use more core kernel concepts
(like ww-mutexes). msm gets per-process pagetables, older AMD SI cards
get DC support, nouveau got a bump in displayport support with common
code extraction from i915.
Outside of drm this contains a couple of patches for hexint
moduleparams which you've acked, and a virtio common code tree that
you should also get via it's regular path.

Bug fix pull for IPMI for 5.10
Some minor bug fixes, return values, cleanups of prints, conversion of tasklets to the new API. The biggest change is retrying the initial information fetch from the management controller. If that fails, the iterface is not operational, and one group was having trouble with the management controller not being ready when the OS started up. So a retry was added. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE/Q1c5nzg9ZpmiCaGYfOMkJGb/4EFAl+Fzb0ACgkQYfOMkJGb /4F84w//RX/gaI1LkhkMKjrvtepNOElijAePFdPdCNYHvE+c50cADNHLstiQVaGk 3URa/F1ba9LNlYsof9Y2L4PT5m6UUhmzWbJ3i0CZRJoqZUB4cZAzwrzHAG4oDqdG C8bO4mSHsglE5uTeZ7WPquzqfF7Jjq53tmVHRUYAc9MhAFph2x+8uW+zpyU/Y47a QMVdn3cE69B80IuZPa6puAlRKhF6M4RpfGCFgKzBXz4Hbf+3V290hI5ulwU60PV7 MLrnsHbQzNybdKRN78nnBVB0bXIZDxz92Nk4HYjYIJhZYleVdZVH6BiFOa2ZpkxP F2rrsztjhaKV1fSXfxGivFATsrmcZ9zw7crYSmZBMoRQcr4gjG4LqPI+feBFZ3oy V8LtNcLQHM7v62iOfGIP83mOezhgF9S0I/HuCliB0V5GXRJv7MfrMKmmgCzCchuK koFgcWBGFzTDPRhjUeK1YyMxyM/F1JjRs8fK7qaG9e4hmqtGyE6nlg0W15VlPCt6 jBGjy4Vn4WMNSdn/XBd/i4UEL1yOCaHbUrLexZc2+q3dlpWOcQ19JwQTkSLY95bM IrIKjLy7Rbnnnji1tAYgzqV2RzY3g35/Vv4T7XI9HDPplasCWUV/7+BDMNy2A8ec kq/bvwl3aoPiXKXDe512SyPR1R0b/SJWkdzLdznMGtOIqNnjjac= =t7Qa -----END PGP SIGNATURE----- Merge tag 'for-linus-5.10-1' of git://github.com/cminyard/linux-ipmi Pull IPMI updates from Corey Minyard: "Some minor bug fixes, return values, cleanups of prints, conversion of tasklets to the new API.
