2022-06-10fscrypt: Add HCTR2 support for filename encryptionNathan Huckleberry
HCTR2 is a tweakable, length-preserving encryption mode that is intended for use on CPUs with dedicated crypto instructions. HCTR2 has the property that a bitflip in the plaintext changes the entire ciphertext. This property fixes a known weakness with filename encryption: when two filenames in the same directory share a prefix of >= 16 bytes, with AES-CTS-CBC their encrypted filenames share a common substring, leaking information. HCTR2 does not have this problem.

2022-06-10crypto: arm64/polyval - Add PMULL accelerated implementation of POLYVALNathan Huckleberry
Add hardware accelerated version of POLYVAL for ARM64 CPUs with Crypto Extensions support. This implementation is accelerated using PMULL instructions to perform the finite field computations. For added efficiency, 8 blocks of the message are processed simultaneously by precomputing the first 8 powers of the key. Karatsuba multiplication is used instead of Schoolbook multiplication because it was found to be slightly faster on ARM64 CPUs. Montgomery reduction must be used instead of Barrett reduction due to the difference in modulus between POLYVAL's field and other finite fields.

2022-06-10crypto: hctr2 - Add HCTR2 supportNathan Huckleberry
Add support for HCTR2 as a template. HCTR2 is a length-preserving encryption mode that is efficient on processors with instructions to accelerate AES and carryless multiplication, e.g. x86 processors with AES-NI and CLMUL, and ARM processors with the ARMv8 Crypto Extensions. As a length-preserving encryption mode, HCTR2 is suitable for applications such as storage encryption where ciphertext expansion is not possible, and thus authenticated encryption cannot be used. Currently, such applications usually use XTS, or in some cases Adiantum. XTS has the disadvantage that it is a narrow-block mode: a bitflip will only change 16 bytes in the resulting ciphertext or plaintext. This reveals more information to an attacker than necessary. HCTR2 is a wide-block mode, so it provides a stronger security property: a bitflip will change the entire message. HCTR2 is somewhat similar to Adiantum, which is also a wide-block mode. However, HCTR2 is designed to take advantage of existing crypto instructions, while Adiantum targets devices without such hardware support. Adiantum is also designed with longer messages in mind, while HCTR2 is designed to be efficient even on short messages. HCTR2 requires POLYVAL and XCTR as components.

2022-06-10crypto: polyval - Add POLYVAL supportNathan Huckleberry
Add support for POLYVAL, an ε-Δ-universal hash function similar to GHASH. This patch only uses POLYVAL as a component to implement HCTR2 mode. It should be noted that POLYVAL was originally specified for use in AES-GCM-SIV (RFC 8452), but the kernel does not currently support this mode. POLYVAL is implemented as an shash algorithm. The implementation is modified from ghash-generic.c.

2022-06-10crypto: xctr - Add XCTR supportNathan Huckleberry
Add a generic implementation of XCTR mode as a template. XCTR is a blockcipher mode similar to CTR mode. XCTR uses XORs and little-endian addition rather than big-endian arithmetic which has two advantages: It is slightly faster on little-endian CPUs and it is less likely to be implemented incorrect since integer overflows are not possible on practical input sizes. XCTR is used as a component to implement HCTR2.

2022-06-10crypto: atmel-ecc - Remove duplicated error reporting in .remove()Uwe Kleine-König
Returning an error value in an i2c remove callback results in an error message being emitted by the i2c core, but otherwise it doesn't make a difference. The device goes away anyhow and the devm cleanups are called. As atmel_ecc_remove() already emits an error message on failure and the additional error message by the i2c core doesn't add any useful information, change the return value to zero to suppress this message. Also make the error message a bit more drastical because when the device is still busy on remove, it's likely that it will access freed memory soon. This patch is a preparation for making i2c remove callbacks return void.

2022-06-10crypto: ccp - Use kzalloc for sev ioctl interfaces to prevent kernel memory leakJohn Allen
For some sev ioctl interfaces, input may be passed that is less than or equal to SEV_FW_BLOB_MAX_SIZE, but larger than the data that PSP firmware returns. In this case, kmalloc will allocate memory that is the size of the input rather than the size of the data. Since PSP firmware doesn't fully overwrite the buffer, the sev ioctl interfaces with the issue may return uninitialized slab memory. Currently, all of the ioctl interfaces in the ccp driver are safe, but to prevent future problems, change all ioctl interfaces that allocate memory with kmalloc to use kzalloc and memset the data buffer to zero in sev_ioctl_do_platform_status.

2022-06-05bluetooth: don't use bitmaps for random flag accessesLinus Torvalds
The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953fd221 ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

The infrastructure provided allows for drivers to register as hardware timestamp providers, while consumers will be able to request events that they are interested in (such as GPIOs and IRQs) to be timestamped by the hardware providers. Note that this currently supports only one provider, but there seems to be enough interest in this functionality and we expect to see more drivers added once this is merged" [ Linus Walleij mentions the Intel PMC in the Elkhart and Tiger Lake platforms as another future timestamp provider ] * tag 'hte/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: dt-bindings: timestamp: Correct id path dt-bindings: Renamed hte directory to timestamp hte: Uninitialized variable in hte_ts_get() hte: Fix off by one in hte_push_ts_ns() hte: Fix possible use-after-free in tegra_hte_test_remove() hte: Remove unused including <linux/version.h> MAINTAINERS: Add HTE Subsystem hte: Add Tegra HTE test driver tools: gpio: Add new hardware clock type gpiolib: cdev: Add hardware timestamp clock type gpio: tegra186: Add HTE support gpiolib: Add HTE support dt-bindings: Add HTE bindings hte: Add Tegra194 HTE kernel provider drivers: Add hardware timestamp engine (HTE) subsystem Documentation: Add HTE subsystem guide

2022-06-05modpost: simplify mod->name allocationMasahiro Yamada
mod->name is set to the ELF filename with the suffix ".o" stripped. The current code calls strdup() and free() to manipulate the string, but a simpler approach is to pass new_module() with the name length subtracted by 2. Also, check if the passed filename ends with ".o" before stripping it. The current code blindly chops the suffix: tmp[strlen(tmp) - 2] = '\0' It will cause buffer under-run if strlen(tmp) < 2; Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com>
2022-06-05kbuild: factor out the common objtool argumentsMasahiro Yamada
scripts/Makefile.build and scripts/link-vmlinux.sh have similar setups for the objtool arguments. It was difficult to factor out them because all the vmlinux build rules were written in a shell script. It is somewhat tedious to touch the two files every time a new objtool option is supported. To reduce the code duplication, move the objtool for vmlinux.o into scripts/Makefile.vmlinux_o. Then, move the common macros to Makefile.lib so they are shared between Makefile.build and Makefile.vmlinux_o.

Rename the record directory of objdiff, .tmp_objdiff to .objdiff to avoid the removal by "make clean".
