As we work towards promoting IMA/EVM to a "proper LSM" instead of the special case that it is now, we need to better support the case of multiple LSMs each adding xattrs to an inode and after several attempts we now appear to have something that is working well. It is worth noting that in the process of making this change we uncovered a problem with Smack's SMACK64TRANSMUTE xattr which is also fixed in this pull request. - Additional LSM hook constification Two patches to constify parameters to security_capget() and security_binder_transfer_file(). While I generally don't make a special note of who submitted these patches, these were the work of an Outreachy intern, Khadija Kamran, and that makes me happy; hopefully it does the same for all of you reading this. - LSM hook comment header fixes One patch to add a missing hook comment header, one to fix a minor typo. - Remove an old, unused credential function declaration It wasn't clear to me who should pick this up, but it was trivial, obviously correct, and arguably the LSM layer has a vested interest in credentials so I merged it. Sadly I'm now noticing that despite my subject line cleanup I didn't cleanup the "unsued" misspelling, sigh * tag 'lsm-pr-20230829' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: lsm: constify the 'file' parameter in security_binder_transfer_file() lsm: constify the 'target' parameter in security_capget() lsm: add comment block for security_sk_classify_flow LSM hook security: Fix ret values doc for security_inode_init_security() cred: remove unsued extern declaration change_create_files_as() evm: Support multiple LSMs providing an xattr evm: Align evm_inode_init_security() definition with LSM infrastructure smack: Set the SMACK64TRANSMUTE xattr in smack_inode_init_security() security: Allow all LSMs to provide xattrs for inode_init_security hook lsm: fix typo in security_file_lock() comment header
