Revision efa916af13206eb15916e102c45c99a13ea78f33 authored by Linus Torvalds on 31 August 2021, 21:55:09 UTC, committed by Linus Torvalds on 31 August 2021, 21:55:09 UTC
Pull device mapper updates from Mike Snitzer: - Add DM infrastructure for IMA-based remote attestion. These changes are the basis for deploying DM-based storage in a "cloud" that must validate configurations end-users run to maintain trust. These DM changes allow supported DM targets' configurations to be measured via IMA. But the policy and enforcement (of which configurations are valid) is managed by something outside the kernel (e.g. Keylime). - Fix DM crypt scalability regression on systems with many cpus due to percpu_counter spinlock contention in crypt_page_alloc(). - Use in_hardirq() instead of deprecated in_irq() in DM crypt. - Add event counters to DM writecache to allow users to further assess how the writecache is performing. - Various code cleanup in DM writecache's main IO mapping function. * tag 'for-5.15/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm crypt: use in_hardirq() instead of deprecated in_irq() dm ima: update dm documentation for ima measurement support dm ima: update dm target attributes for ima measurements dm ima: add a warning in dm_init if duplicate ima events are not measured dm ima: prefix ima event name related to device mapper with dm_ dm ima: add version info to dm related events in ima log dm ima: prefix dm table hashes in ima log with hash algorithm dm crypt: Avoid percpu_counter spinlock contention in crypt_page_alloc() dm: add documentation for IMA measurement support dm: update target status functions to support IMA measurement dm ima: measure data on device rename dm ima: measure data on table clear dm ima: measure data on device remove dm ima: measure data on device resume dm ima: measure data on table load dm writecache: add event counters dm writecache: report invalid return from writecache_map helpers dm writecache: further writecache_map() cleanup dm writecache: factor out writecache_map_remap_origin() dm writecache: split up writecache_map() to improve code readability
