md: reintroduce md-linear

2025-02-17T09:05:04+00:00

commit 127186cfb184eaccdfe948e6da66940cfa03efc5 upstream. THe md-linear is removed by commit 849d18e27be9 ("md: Remove deprecated CONFIG_MD_LINEAR") because it has been marked as deprecated for a long time. However, md-linear is used widely for underlying disks with different size, sadly we didn't know this until now, and it's true useful to create partitions and assemble multiple raid and then append one to the other. People have to use dm-linear in this case now, however, they will prefer to minimize the number of involved modules.

dm verity: add support for signature verification with platform keyring

2024-07-03T19:41:11+00:00

Add a new configuration CONFIG_DM_VERITY_VERIFY_ROOTHASH_SIG_PLATFORM_KEYRING that enables verifying dm-verity signatures using the platform keyring, which is populated using the UEFI DB certificates. This is useful for self-enrolled systems that do not use MOK, as the secondary keyring which is already used for verification, if the relevant kconfig is enabled, is linked to the machine keyring, which gets its certificates loaded from MOK. On datacenter/virtual/cloud deployments it is more common to deploy one's own certificate chain directly in DB on first boot in unattended mode, rather than relying on MOK, as the latter typically requires interactive authentication to enroll, and is more suited for personal machines. Default to the same value as DM_VERITY_VERIFY_ROOTHASH_SIG_SECONDARY_KEYRING if not otherwise specified, as it is likely that if one wants to use MOK certificates to verify dm-verity volumes, DB certificates are going to be used too. Keys in DB are allowed to load a full kernel already anyway, so they are already highly privileged. Signed-off-by: Luca Boccassi Signed-off-by: Mikulas Patocka

dm vdo: use a proper Makefile for dm-vdo

2024-02-20T18:43:17+00:00

Requires moving dm-vdo-target.c into drivers/md/dm-vdo/ This change adds a proper drivers/md/dm-vdo/Makefile and eliminates the abnormal use of patsubst in drivers/md/Makefile -- which was the cause of at least one build failure that was reported by the upstream build bot. Also, split out VDO's drivers/md/dm-vdo/Kconfig and include it from drivers/md/Kconfig Signed-off-by: Mike Snitzer Signed-off-by: Matthew Sakai

dm vdo: enable configuration and building of dm-vdo

2024-02-20T18:43:16+00:00

dm-vdo targets are not supported for 32-bit configurations. A vdo target typically requires 1 to 1.5 GB of memory at any given time, which is likely a large fraction of the addressable memory of a 32-bit system. At the same time, the amount of addressable storage attached to a 32-bit system may not be large enough for deduplication to provide much benefit. Because of these concerns, 32-bit platforms are deemed unlikely to benefit from using a vdo target, so dm-vdo is targeted only at 64-bit platforms.

treewide: replace or remove redundant def_bool in Kconfig files

2024-02-20T11:47:45+00:00

'def_bool X' is a shorthand for 'bool' plus 'default X'. 'def_bool' is redundant where 'bool' is already present, so 'def_bool X' can be replaced with 'default X', or removed if X is 'n'. Signed-off-by: Masahiro Yamada
