2023-04-24drm/dsc: fix drm_edp_dsc_sink_output_bpp() DPCD high byte usageJani Nikula
The operator precedence between << and & is wrong, leading to the high byte being completely ignored. For example, with the 6.4 format, 32 becomes 0 and 24 becomes 8. Fix it, and remove the slightly confusing and unnecessary DP_DSC_MAX_BITS_PER_PIXEL_HI_SHIFT macro while at it.

git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd Pull tpm updates from Jarkko Sakkinen: - The .machine keyring, used for Machine Owner Keys (MOK), acquired the ability to store only CA enforced keys, and put rest to the .platform keyring, thus separating the code signing keys from the keys that are used to sign certificates. This essentially unlocks the use of the .machine keyring as a trust anchor for IMA. It is an opt-in feature, meaning that the additional contraints won't brick anyone who does not care about them. - Enable interrupt based transactions with discrete TPM chips (tpm_tis). There was code for this existing but it never really worked so I consider this a new feature rather than a bug fix. Before the driver just fell back to the polling mode.

2023-04-24Merge tag 'lsm-pr-20230420' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm Pull lsm updates from Paul Moore: - Move the LSM hook comment blocks into security/security.c For many years the LSM hook comment blocks were located in a very odd place, include/linux/lsm_hooks.h, where they lived on their own, disconnected from both the function prototypes and definitions. In keeping with current kernel conventions, this moves all of these comment blocks to the top of the function definitions, transforming them into the kdoc format in the process. This should make it much easier to maintain these comments, which are the main source of LSM hook documentation. For the most part the comment contents were left as-is, although some glaring errors were corrected. Expect additional edits in the future as we slowly update and correct the comment blocks. This is the bulk of the diffstat. - Introduce LSM_ORDER_LAST Similar to how LSM_ORDER_FIRST is used to specify LSMs which should be ordered before "normal" LSMs, the LSM_ORDER_LAST is used to specify LSMs which should be ordered after "normal" LSMs. This is one of the prerequisites for transitioning IMA/EVM to a proper LSM. - Remove the security_old_inode_init_security() hook The security_old_inode_init_security() LSM hook only allows for a single xattr which is problematic both for LSM stacking and the IMA/EVM-as-a-LSM effort. This finishes the conversion over to the security_inode_init_security() hook and removes the single-xattr LSM hook. - Fix a reiserfs problem with security xattrs During the security_old_inode_init_security() removal work it became clear that reiserfs wasn't handling security xattrs properly so we fixed it. * tag 'lsm-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (32 commits) reiserfs: Add security prefix to xattr name in reiserfs_security_write() security: Remove security_old_inode_init_security() ocfs2: Switch to security_inode_init_security() reiserfs: Switch to security_inode_init_security() security: Remove integrity from the LSM list in Kconfig Revert "integrity: double check iint_cache was initialized" security: Introduce LSM_ORDER_LAST and set it for the integrity LSM device_cgroup: Fix typo in devcgroup_css_alloc description lsm: fix a badly named parameter in security_get_getsecurity() lsm: fix doc warnings in the LSM hook comments lsm: styling fixes to security/security.c lsm: move the remaining LSM hook comments to security/security.c lsm: move the io_uring hook comments to security/security.c lsm: move the perf hook comments to security/security.c lsm: move the bpf hook comments to security/security.c lsm: move the audit hook comments to security/security.c lsm: move the binder hook comments to security/security.c lsm: move the sysv hook comments to security/security.c lsm: move the key hook comments to security/security.c lsm: move the xfrm hook comments to security/security.c ...
2023-04-24Merge tag 'selinux-pr-20230420' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux Pull selinux updates from Paul Moore: - Stop passing the 'selinux_state' pointers as function arguments As discussed during the end of the last development cycle, passing a selinux_state pointer through the SELinux code has a noticeable impact on performance, and with the current code it is not strictly necessary. This simplifies things by referring directly to the single selinux_state global variable which should help improve SELinux performance. - Uninline the unlikely portions of avc_has_perm_noaudit() This change was also based on a discussion from the last development cycle, and is heavily based on an initial proof of concept patch from you. The core issue was that avc_has_perm_noaudit() was not able to be inlined, as intended, due to its size. We solved this issue by extracting the less frequently hit portions of avc_has_perm_noaudit() into a separate function, reducing the size of avc_has_perm_noaudit() to the point where the compiler began inlining the function. We also took the opportunity to clean up some ugly RCU locking in the code that became uglier with the change. - Remove the runtime disable functionality After several years of work by the userspace and distro folks, we are finally in a place where we feel comfortable removing the runtime disable functionality which we initially deprecated at the start of 2020. There is plenty of information in the kernel's deprecation (now removal) notice, but the main motivation was to be able to safely mark the LSM hook structures as '__ro_after_init'. LWN also wrote a good summary of the deprecation this morning which offers a more detailed history: https://lwn.net/SubscriberLink/927463/dcfa0d4ed2872f03 - Remove the checkreqprot functionality The original checkreqprot deprecation notice stated that the removal would happen no sooner than June 2021, which means this falls hard into the "better late than never" bucket. The Kconfig and deprecation notice has more detail on this setting, but the basic idea is that we want to ensure that the SELinux policy allows for the memory protections actually applied by the kernel, and not those requested by the process. While we haven't found anyone running a supported distro that is affected by this deprecation/removal, anyone who is affected would only need to update their policy to reflect the reality of their applications' mapping protections. - Minor Makefile improvements Some minor Makefile improvements to correct some dependency issues likely only ever seen by SELinux developers. I expect we will have at least one more tweak to the Makefile during the next merge window, but it didn't quite make the cutoff this time around. * tag 'selinux-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: ensure av_permissions.h is built when needed selinux: fix Makefile dependencies of flask.h selinux: stop returning node from avc_insert() selinux: clean up dead code after removing runtime disable selinux: update the file list in MAINTAINERS selinux: remove the runtime disable functionality selinux: remove the 'checkreqprot' functionality selinux: stop passing selinux_state pointers and their offspring selinux: uninline unlikely parts of avc_has_perm_noaudit()

The key usage extension defines the purpose of the key contained in the certificate. id-ce-keyUsage OBJECT IDENTIFIER ::= { id-ce 15 } KeyUsage ::= BIT STRING { digitalSignature (0), contentCommitment (1), keyEncipherment (2), dataEncipherment (3), keyAgreement (4), keyCertSign (5), cRLSign (6), encipherOnly (7), decipherOnly (8) } If the keyCertSign or digitalSignature is set, store it in the public_key structure. Having the purpose of the key being stored during parsing, allows enforcement on the usage field in the future. This will be used in a follow on patch that requires knowing the certificate key usage type.

2023-04-23Bluetooth: Add support for hci devcoredumpAbhishek Pandit-Subedi
Add devcoredump APIs to hci core so that drivers only have to provide the dump skbs instead of managing the synchronization and timeouts. The devcoredump APIs should be used in the following manner: - hci_devcoredump_init is called to allocate the dump. - hci_devcoredump_append is called to append any skbs with dump data OR hci_devcoredump_append_pattern is called to insert a pattern. - hci_devcoredump_complete is called when all dump packets have been sent OR hci_devcoredump_abort is called to indicate an error and cancel an ongoing dump collection. The high level APIs just prepare some skbs with the appropriate data and queue it for the dump to process. Packets part of the crashdump can be intercepted in the driver in interrupt context and forwarded directly to the devcoredump APIs. Internally, there are 5 states for the dump: idle, active, complete, abort and timeout. A devcoredump will only be in active state after it has been initialized. Once active, it accepts data to be appended, patterns to be inserted (i.e. memset) and a completion event or an abort event to generate a devcoredump. The timeout is initialized at the same time the dump is initialized (defaulting to 10s) and will be cleared either when the timeout occurs or the dump is complete or aborted.

2023-04-23net: dsa: tag_ocelot: call only the relevant portion of __skb_vlan_pop() on TXVladimir Oltean
ocelot_xmit_get_vlan_info() calls __skb_vlan_pop() as the most appropriate helper I could find which strips away a VLAN header. That's all I need it to do, but __skb_vlan_pop() has more logic, which will become incompatible with the future revert of commit 6d1ccff62780 ("net: reset mac header in dev_start_xmit()"). Namely, it performs a sanity check on skb_mac_header(), which will stop being set after the above revert, so it will return an error instead of removing the VLAN tag. ocelot_xmit_get_vlan_info() gets called in 2 circumstances: (1) the port is under a VLAN-aware bridge and the bridge sends VLAN-tagged packets (2) the port is under a VLAN-aware bridge and somebody else (an 8021q upper) sends VLAN-tagged packets (using a VID that isn't in the bridge vlan tables) In case (1), there is actually no bug to defend against, because br_dev_xmit() calls skb_reset_mac_header() and things continue to work. However, in case (2), illustrated using the commands below, it can be seen that our intervention is needed, since __skb_vlan_pop() complains: $ ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up $ ip link set $eth master br0 && ip link set $eth up $ ip link add link $eth name $eth.100 type vlan id 100 && ip link set $eth.100 up $ ip addr add 192.168.100.1/24 dev $eth.100 I could fend off the checks in __skb_vlan_pop() with some skb_mac_header_was_set() calls, but seeing how few callers of __skb_vlan_pop() there are from TX paths, that seems rather unproductive. As an alternative solution, extract the bare minimum logic to strip a VLAN header, and move it to a new helper named vlan_remove_tag(), close to the definition of vlan_insert_tag(). Document it appropriately and make ocelot_xmit_get_vlan_info() call this smaller helper instead. Seeing that it doesn't appear illegal to test skb->protocol in the TX path, I guess it would be a good for vlan_remove_tag() to also absorb the vlan_set_encap_proto() function call.
