2020-06-26docs: hugetlbpage.rst: fix some warningsMauro Carvalho Chehab1-6/+17
Some new command line parameters were added at hugetlbpage.rst.

2020-06-26selftests/vm/keys: fix a broken reference at protection_keys.cMauro Carvalho Chehab1-1/+1
Changeset 1eecbcdca2bd ("docs: move protection-keys.rst to the core-api book") from Jun 7, 2019 converted protection-keys.txt file to ReST. A recent change at protection_keys.c partially reverted such changeset, causing it to point to a non-existing file: - * Tests x86 Memory Protection Keys (see Documentation/core-api/protection-keys.rst) + * Tests Memory Protection Keys (see Documentation/vm/protection-keys.txt) It sounds to me that the changeset that introduced such change 4645e3563673 ("selftests/vm/pkeys: rename all references to pkru to a generic name") could also have other side effects, as it sounds that it was not generated against uptream code, but, instead, against a version older than Jun 7, 2019.

2020-06-26kcsan: fix a kernel-doc warningMauro Carvalho Chehab1-4/+6
One of the kernel-doc markups there have two "note" sections: ./include/linux/kcsan-checks.h:346: warning: duplicate section name 'Note' While this is not the case here, duplicated sections can cause build issues on Sphinx. So, let's change the notes section to use, instead, a list for those 2 notes at the same function.

Commit ed318a6cc0b6 ("fscrypt: support test_dummy_encryption=v2") added an entry to the massive option table in Documentation/filesystems/f2fs.txt.

The sphinx-pre-install script will put out a verbose message recommending an upgrade for anybody running less than 2.4.4 - which was only released in March. So *everybody* will see that warning at this point. Let's only warn if the user is below our generally recommended version (1.7.9 currently). It might be good to put out a warning if people are explicitly making PDF files, but would need to be done in a different place and relatively few people do that.

The work to do that is not yet complete, so probably won't make it in for v5.8, but we are looking to get this simple patch in for v5.8 since we have it ready. We are planning on the rest of the work for extending the SafeSetID LSM being merged during the v5.9 merge window" * tag 'LSM-add-setgid-hook-5.8-author-fix' of git://github.com/micah-morton/linux: security: Add LSM hooks to set*gid syscalls
2020-06-14security: Add LSM hooks to set*gid syscallsThomas Cedeno5-1/+40
The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot.
