2022-01-31crypto: memneq - avoid implicit unaligned accessesArd Biesheuvel1-7/+15
The C standard does not support dereferencing pointers that are not aligned with respect to the pointed-to type, and doing so is technically undefined behavior, even if the underlying hardware supports it. This means that conditionally dereferencing such pointers based on whether CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y is not the right thing to do, and actually results in alignment faults on ARM, which are fixed up on a slow path. Instead, we should use the unaligned accessors in such cases: on architectures that don't care about alignment, they will result in identical codegen whereas, e.g., codegen on ARM will avoid doubleword loads and stores but use ordinary ones, which are able to tolerate misalignment.

2022-01-31crypto: rsa-pkcs1pad - restore signature length checkEric Biggers1-1/+1
RSA PKCS#1 v1.5 signatures are required to be the same length as the RSA key size. RFC8017 specifically requires the verifier to check this (https://datatracker.ietf.org/doc/html/rfc8017#section-8.2.2). Commit a49de377e051 ("crypto: Add hash param to pkcs1pad") changed the kernel to allow longer signatures, but didn't explain this part of the change; it seems to be unrelated to the rest of the commit. Revert this change, since it doesn't appear to be correct. We can be pretty sure that no one is relying on overly-long signatures (which would have to be front-padded with zeroes) being supported, given that they would have been broken since commit c7381b012872 ("crypto: akcipher - new verify API for public key algorithms").

2022-01-31crypto: rsa-pkcs1pad - correctly get hash from source scatterlistEric Biggers1-1/+1
Commit c7381b012872 ("crypto: akcipher - new verify API for public key algorithms") changed akcipher_alg::verify to take in both the signature and the actual hash and do the signature verification, rather than just return the hash expected by the signature as was the case before. To do this, it implemented a hack where the signature and hash are concatenated with each other in one scatterlist. Obviously, for this to work correctly, akcipher_alg::verify needs to correctly extract the two items from the scatterlist it is given. Unfortunately, it doesn't correctly extract the hash in the case where the signature is longer than the RSA key size, as it assumes that the signature's length is equal to the RSA key size. This causes a prefix of the hash, or even the entire hash, to be taken from the *signature*. (Note, the case of a signature longer than the RSA key size should not be allowed in the first place; a separate patch will fix that.) It is unclear whether the resulting scheme has any useful security properties. Fix this by correctly extracting the hash from the scatterlist.

2022-01-31crypto: qat - fix access to PFVF interrupt registers for GEN4Giovanni Cabiddu1-33/+9
The logic that detects, enables and disables pfvf interrupts was expecting a single CSR per VF. Instead, the source and mask register are two registers with a bit per VF. Due to this, the driver is reading and setting reserved CSRs and not masking the correct source of interrupts. Fix the access to the source and mask register for QAT GEN4 devices by removing the outer loop in adf_gen4_get_vf2pf_sources(), adf_gen4_enable_vf2pf_interrupts() and adf_gen4_disable_vf2pf_interrupts() and changing the helper macros ADF_4XXX_VM2PF_SOU and ADF_4XXX_VM2PF_MSK.

As testmgr is part of cryptomgr which was designed to be unloadable as a module, it shouldn't export any symbols for other crypto modules to use as that would prevent it from being unloaded. All its functionality is meant to be accessed through notifiers. The symbol crypto_simd_disabled_for_test was added to testmgr which caused it to be pinned as a module if its users were also loaded. This patch moves it out of testmgr and into crypto/algapi.c so cryptomgr can again be unloaded and replaced on demand.

2022-01-30video: fbdev: fbcvt.c: fix printing in fb_cvt_print_name()Dan Carpenter1-31/+20
This code has two bugs: 1) "cnt" is 255 but the size of the buffer is 256 so the last byte is not used. 2) If we try to print more than 255 characters then "cnt" will be negative and that will trigger a WARN() in snprintf(). The fix for this is to use scnprintf() instead of snprintf(). We can re-write this code to be cleaner: 1) Rename "offset" to "off" because that's shorter. 2) Get rid of the "cnt" variable and just use "size - off" directly. 3) Get rid of the "read" variable and just increment "off" directly.

2022-01-30fs: Remove FIXME comment in generic_write_checks()Tal Zussman1-1/+0
This patch removes an unnecessary comment that had to do with block special files from `generic_write_checks()`. The comment, originally added in Linux v2.4.14.9, was to clarify that we only set `pos` to the file size when the file was opened with `O_APPEND` if the file wasn't a block special file. Prior to Linux v2.4, block special files had a different `write()` function which was unified into a generic `write()` function in Linux v2.4. This generic `write()` function called `generic_write_checks()`. For more details, see this earlier conversation: https://lore.kernel.org/linux-fsdevel/Yc4Czk5A+p5p2Y4W@mit.edu/ Currently, block special devices have their own `write_iter()` function and no longer share the same `generic_write_checks()`, therefore rendering the comment irrelevant.

x86 boards may use ACPI HID "TXNW1010" for the hdc100x device. TI told us "The ACPI ID for TI is: https://uefi.org/node/1028 (TXNW), therefore it would most likely be appropriate to use TXNW1010."

2022-01-30Revert "fs/9p: search open fids first"Dominique Martinet1-5/+4
This reverts commit 478ba09edc1f2f2ee27180a06150cb2d1a686f9c. That commit was meant as a fix for setattrs with by fd (e.g. ftruncate) to use an open fid instead of the first fid it found on lookup. The proper fix for that is to use the fid associated with the open file struct, available in iattr->ia_file for such operations, and was actually done just before in 66246641609b ("9p: retrieve fid from file when file instance exist.") As such, this commit is no longer required. Furthermore, changing lookup to return open fids first had unwanted side effects, as it turns out the protocol forbids the use of open fids for further walks (e.g. clone_fid) and we broke mounts for some servers enforcing this rule. Note this only reverts to the old working behaviour, but it's still possible for lookup to return open fids if dentry->d_fsdata is not set, so more work is needed to make sure we respect this rule in the future, for example by adding a flag to the lookup functions to only match certain fid open modes depending on caller requirements.
