Hi John, The first patch in this series fix a bad character used instead of a "(c)" UTF-8 symbol. The remaining ones fix several broken references to files under Documentation/, several due to DT schema conversions from .txt to .yaml.

[RFC PATCH v4 0/2] Introduce XSAVE/XRSTOR self-test

by Pengfei Xu

The XSAVE feature set supports the saving and restoring of state components, which is used for process context switching. The state components include x87 state for FPU execution environment, SSE state, AVX state and so on. In order to ensure that XSAVE works correctly, add XSAVE basic test for XSAVE architecture functionality. This patch set tests and verifies the basic functions of XSAVE/XRSTOR in user space; during and after signal processing on the x86 platform, the XSAVE contents of the process should not be changed. This series introduces only the most basic XSAVE tests. In the future, the intention is to continue expanding the scope of these selftests to include more kernel XSAVE-related functionality and XSAVE-managed features like AMX and shadow stacks. ======== - Change from v3 to v4: - Improve the comment in patch 1. - Change from v2 to v3: - Improve the description of patch 2 git log. - Change from v1 to v2: - Improve the cover-letter.

[PATCH] selftests: be sure to make khdr before other targets

by Li Zhijian

LKP/0Day reported some building errors about kvm, and errors message are not always same: - lib/x86_64/processor.c:1083:31: error: ‘KVM_CAP_NESTED_STATE’ undeclared (first use in this function); did you mean ‘KVM_CAP_PIT_STATE2’? - lib/test_util.c:189:30: error: ‘MAP_HUGE_16KB’ undeclared (first use in this function); did you mean ‘MAP_HUGE_16GB’? Although kvm relies on the khdr, they still be built in parallel when -j is specified. In this case, it will cause compiling errors. Here we mark target khdr as NOTPARALLEL to make it be always built first.

[RFC][PATCH 0/9] integrity: Introduce DIGLIM advanced features

by Roberto Sassu

Introduction ============ This patch set depends on: - support for the euid policy keyword for critical data (https://lore.kernel.org/linux-integrity/20210705115650.3373599-1-roberto.sa…) - basic DIGLIM (https://lore.kernel.org/linux-integrity/20210914163401.864635-1-roberto.sas…) Introduce the remaining features necessary to upload to the kernel reference values from RPM headers or digest lists in other formats. Loader: it will automatically uploads digest lists from a directory specified in the kernel configuration and will execute a user space uploader to upload digest lists in a format that is not recognized by the kernel; LSM: it identifies digest list parsers and monitor their activity for integrity evaluation; it protects digest list parsers from other user space processes considered as untrusted; Digest list generators: user space tools to generate digest lists from files (in the compact format) or from the RPM DB; Digest list uploader and parsers: user space tools responsible to upload to the kernel digest lists not in the compact format (e.g. those derived from the RPM DB); Administration guide: it describes the steps necessary to upload to the kernel all the digests of an RPM-based Linux distribution, using a custom kernel with the DIGLIM patches applied. With these changes, DIGLIM is ready to be used by IMA for measurement and appraisal (this functionality will be added with a future patch set). DIGLIM already supports appended signatures, but at the moment they cannot be interpreted by IMA (unsupported ID PKEY_ID_PGP). Another patch set is necessary to load the PGP keys from the Linux distribution to the system keyring and to verify the PGP signatures of the RPM headers. With the patch sets above and the execution policies for IMA proposed some time ago, it will be possible to generate a measurement list with digest lists and unknown files, and enable IMA appraisal in enforcing mode. The kernel command line would be: ima_template=ima-modsig ima_policy="exec_tcb|tmpfs|digest_lists|appraise_exec_tcb|appraise_tmpfs|appraise_digest_lists" The effort required for Linux distribution vendors will be to generate and sign the digest lists for the digest list uploader and the RPM parser. This could be done for example in the kernel-tools package (or in a separate package). Existing package signatures are sufficient for remaining files. Issues/Questions ================ Lockdep (patch 2/9) ------------------- I'm using iterate_dir() and file_open_root() to iterate and open files in a directory. Unfortunately, I get the following warning: ============================================ WARNING: possible recursive locking detected 5.15.0-rc1-dont-use-00049-ga5a881519991 #134 Not tainted -------------------------------------------- swapper/1 is trying to acquire lock: 0000000066812898 (&sb->s_type->i_mutex_key#7){++++}-{4:4}, at: path_openat+0x75d/0xd20 but task is already holding lock: 0000000066812898 (&sb->s_type->i_mutex_key#7){++++}-{4:4}, at: iterate_dir+0x65/0x250 other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&sb->s_type->i_mutex_key#7); lock(&sb->s_type->i_mutex_key#7); *** DEADLOCK *** due to the fact that path_openat() might be trying to lock the directory already locked by iterate_dir(). What it would be a good way to avoid it? Inode availability in security_file_free() (patch 3/9) ------------------------------------------------------ It seems that this hook is called when the last reference to a file is released. After enabling debugging, sometimes the kernel reported that the inode I was trying to access was already freed. To avoid this situation, I'm grabbing an additional reference of the inode in the security_file_open() hook, to ensure that the inode does not disappear, and I'm releasing it in the security_file_free() hook. Is this solution acceptable?

Introduce a simple test for Platform Firmware Runtime Update and Telemetry drivers. It is based on ioctl to either update firmware driver or code injection, and read corresponding PFRU Telemetry log into user space.
