Crypto library updates for 6.17
This is the main crypto library pull request for 6.17. The main focus
this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
and establishing conventions for lib/crypto/ going forward:
- Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
most of the SHA-512 code) into lib/crypto/. This includes both the
generic and architecture-optimized code. Greatly simplify how the
architecture-optimized code is integrated. Add an easy-to-use
library API for each SHA variant, including HMAC support. Finally,
reimplement the crypto_shash support on top of the library API.
- Apply the same reorganization to the SHA-256 code (and also SHA-224
which shares most of the SHA-256 code). This is a somewhat smaller
change, due to my earlier work on SHA-256. But this brings in all
the same additional improvements that I made for SHA-1 and SHA-512.
There are also some smaller changes:
- Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
these algorithms it's just a move, not a full reorganization yet.
- Fix the MIPS chacha-core.S to build with the clang assembler.
- Fix the Poly1305 functions to work in all contexts.
- Fix a performance regression in the x86_64 Poly1305 code.
- Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.
Note that since the new organization of the SHA code is much simpler,
the diffstat of this pull request is negative, despite the addition of
new fully-documented library APIs for multiple SHA and HMAC-SHA
variants. These APIs will allow further simplifications across the
kernel as users start using them instead of the old-school crypto API.
(I've already written a lot of such conversion patches, removing over
1000 more lines of code. But most of those will target 6.18 or later.)

securityfs cleanups and fixes:
* one extra reference is enough to pin a dentry down; no need
for two. Switch to regular scheme, similar to shmem, debugfs,
etc. - that fixes securityfs_recursive_remove() dentry leak,
among other things.
* we need to have the filesystem pinned to prevent the contents
disappearing; what we do not need is pinning it for each file.
Doing that only for files and directories in the root is enough.
* the previous two changes allow to get rid of the racy kludges
in efi_secret_unlink(), where we can use simple_unlink() instead
of securityfs_remove(). Which does not require unlocking and
relocking the parent, with all deadlocks that invites.
* Make securityfs_remove() take the entire subtree out, turning
securityfs_recursive_remove() into its alias. Makes a lot more
sense for callers and fixes a mount leak, while we are at it.
* Making securityfs_remove() remove the entire subtree allows for
much simpler life in most of the users - efi_secret, ima_fs,
evm, ipe, tmp get cleaner. I hadn't touched apparmor use of
securityfs, but I suspect that it would be useful there as well.

tpm_crb_ffa: handle tpm busy return code
Platforms supporting direct message request v2 [1] can support secure partitions that support multiple services. For CRB over FF-A interface, if the firmware TPM or TPM service [1] shares its Secure Partition (SP) with another service, message requests may fail with a -EBUSY error. To handle this, replace the single check and call with a retry loop that attempts the TPM message send operation until it succeeds or a configurable timeout is reached. Implement a _try_send_receive function to do a single send/receive and modify the existing send_receive to add this retry loop. The retry mechanism introduces a module parameter (`busy_timeout_ms`, default: 2000ms) to control how long to keep retrying on -EBUSY responses. Between retries, the code waits briefly (50-100 microseconds) to avoid busy-waiting and handling TPM BUSY conditions more gracefully. The parameter can be modified at run-time as such: echo 3000 | tee /sys/module/tpm_crb_ffa/parameters/busy_timeout_ms This changes the timeout from the default 2000ms to 3000ms.

tpm: Check for completion after timeout
The current implementation of timeout detection works in the following way: 1. Read completion status. If completed, return the data 2. Sleep for some time (usleep_range) 3. Check for timeout using current jiffies value. Return an error if timed out 4. Goto 1 usleep_range doesn't guarantee it's always going to wake up strictly in (min, max) range, so such a situation is possible: 1. Driver reads completion status. No completion yet 2. Process sleeps indefinitely. In the meantime, TPM responds 3. We check for timeout without checking for the completion again. Result is lost. Such a situation also happens for the guest VMs: if vCPU goes to sleep and doesn't get scheduled for some time, the guest TPM driver will timeout instantly after waking up without checking for the completion (which may already be in place). Perform the completion check once again after exiting the busy loop in order to give the device the last chance to send us some data. Since now we check for completion in two places, extract this check into a separate function.

tpm: tpm_crb_ffa: try to probe tpm_crb_ffa when it's built-in
To generate the boot_aggregate log in the IMA subsystem using TPM PCR values, the TPM driver must be built as built-in and must be probed before the IMA subsystem is initialized. However, when the TPM device operates over the FF-A protocol using the CRB interface, probing fails and returns -EPROBE_DEFER if the tpm_crb_ffa device — an FF-A device that provides the communication interface to the tpm_crb driver — has not yet been probed. This issue occurs because both crb_acpi_driver_init() and tpm_crb_ffa_driver_init() are registered with device_initcall. As a result, crb_acpi_driver_init() may be invoked before tpm_crb_ffa_driver_init(), which is responsible for probing the tpm_crb_ffa device. When this happens, IMA fails to detect the TPM device and logs the following message: | ima: No TPM chip found, activating TPM-bypass! Consequently, it cannot generate the boot_aggregate log with the PCR values provided by the TPM. To resolve this issue, the tpm_crb_ffa_init() function explicitly attempts to probe the tpm_crb_ffa by register tpm_crb_ffa driver so that when tpm_crb_ffa device is created before tpm_crb_ffa_init(), probe the tpm_crb_ffa device in tpm_crb_ffa_init() to finish probe the TPM device completely. This ensures that the TPM device using CRB over FF-A can be successfully probed, even if crb_acpi_driver_init() is called first.

tpm/tpm_svsm: support TPM_CHIP_FLAG_SYNC
This driver does not support interrupts, and receiving the response is synchronous with sending the command. Enable synchronous send() with TPM_CHIP_FLAG_SYNC, which implies that ->send() already fills the provided buffer with a response, and ->recv() is not implemented. Keep using the same pre-allocated buffer to avoid having to allocate it for each command. We need the buffer to have the header required by the SVSM protocol and the command contiguous in memory.

tpm: support devices with synchronous send()
Some devices do not support interrupts and provide a single synchronous operation to send the command and receive the response on the same buffer. Currently, these types of drivers must use an internal buffer where they temporarily store the response between .send() and .recv() calls. Introduce a new flag (TPM_CHIP_FLAG_SYNC) to support synchronous send(). If that flag is set by the driver, tpm_try_transmit() will use the send() callback to send the command and receive the response on the same buffer synchronously. In that case send() return the number of bytes of the response on success, or -errno on failure.

tpm: add bufsiz parameter in the .send callback
Add a new `bufsiz` parameter to the `.send` callback in `tpm_class_ops`. This parameter will allow drivers to differentiate between the actual command length to send and the total buffer size. Currently `bufsiz` is not used, but it will be used to implement devices with synchronous send() to send the command and receive the response on the same buffer. Also rename the previous parameter `len` to `cmd_len` in the declaration to make it clear that it contains the length in bytes of the command stored in the buffer. The semantics don't change and it can be used as before by drivers. This is an optimization since the drivers could get it from the header, but let's avoid duplicating code. While we are here, resolve a checkpatch warning: WARNING: Unnecessary space before function pointer arguments #66: FILE: include/linux/tpm.h:90: + int (*send) (struct tpm_chip *chip, u8 *buf, size_t bufsiz, Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Suggested-by: Jarkko Sakkinen <jarkko@kernel.org> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org> |

ipmi: Use dev_warn_ratelimited() for incorrect message warnings
During BMC firmware upgrades on live systems, the ipmi_msghandler generates excessive "BMC returned incorrect response" warnings while the BMC is temporarily offline.

lib/crypto: sha256: Make library API use strongly-typed contexts
Currently the SHA-224 and SHA-256 library functions can be mixed arbitrarily, even in ways that are incorrect, for example using sha224_init() and sha256_final(). This is because they operate on the same structure, sha256_state. Introduce stronger typing, as I did for SHA-384 and SHA-512. Also as I did for SHA-384 and SHA-512, use the names *_ctx instead of *_state. The *_ctx names have the following small benefits: - They're shorter. - They avoid an ambiguity with the compression function state. - They're consistent with the well-known OpenSSL API. - Users usually name the variable 'sctx' anyway, which suggests that *_ctx would be the more natural name for the actual struct. Therefore: update the SHA-224 and SHA-256 APIs, implementation, and calling code accordingly. In the new structs, also strongly-type the compression function state.

Restructure the IPMI driver for 6.16

char: tpm: tpm-buf: Add sanity check fallback in read helpers
Fix Smatch-detected issue: drivers/char/tpm/tpm-buf.c:208 tpm_buf_read_u8() error: uninitialized symbol 'value'. drivers/char/tpm/tpm-buf.c:225 tpm_buf_read_u16() error: uninitialized symbol 'value'. drivers/char/tpm/tpm-buf.c:242 tpm_buf_read_u32() error: uninitialized symbol 'value'. Zero-initialize the return values in tpm_buf_read_u8(), tpm_buf_read_u16(), and tpm_buf_read_u32() to guard against uninitialized data in case of a boundary overflow. Add defensive initialization ensures the return values are always defined, preventing undefined behavior if the unexpected happens.

tpm2_start_auth_session() does not mask TPM RC correctly from the callers:
[ 28.766528] tpm tpm0: A TPM error (2307) occurred start auth session
Process TPM RCs inside tpm2_start_auth_session(), and map them to POSIX
error codes.
