dm: add clone target Add the dm-clone target, which allows cloning of arbitrary block devices. dm-clone produces a one-to-one copy of an existing, read-only source device into a writable destination device: It presents a virtual block device which makes all data appear immediately, and redirects reads and writes accordingly. The main use case of dm-clone is to clone a potentially remote, high-latency, read-only, archival-type block device into a writable, fast, primary-type device for fast, low-latency I/O. The cloned device is visible/mountable immediately and the copy of the source device to the destination device happens in the background, in parallel with user I/O. When the cloning completes, the dm-clone table can be removed altogether and be replaced, e.g., by a linear table, mapping directly to the destination device. For further information and examples of how to use dm-clone, please read Documentation/admin-guide/device-mapper/dm-clone.rst Suggested-by: Vangelis Koukis <vkoukis@arrikto.com> Co-developed-by: Ilias Tsitsimpis <iliastsi@arrikto.com> Signed-off-by: Ilias Tsitsimpis <iliastsi@arrikto.com> Signed-off-by: Nikos Tsironis <ntsironis@arrikto.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> | 6 年前 | |
dm crypt: support using trusted keys Commit 27f5411a718c ("dm crypt: support using encrypted keys") extended dm-crypt to allow use of "encrypted" keys along with "user" and "logon". Along the same lines, teach dm-crypt to support "trusted" keys as well. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Mike Snitzer <snitzer@redhat.com> | 5 年前 | |

dm ima: update dm documentation for ima measurement support The ima documentation for measuring DM targets (dm-ima.rst) is missing the attribute information for the targets - 'cache', 'integrity', 'multipath', and 'snapshot'. It is also missing the grammar for various DM events and targets, which can help the attestation servers to determine what data to expect for a given DM device. Further, the documentation needs to be updated to incorporate code changes made to DM ima events and targets as part of this patch series. For instance, prefixing the event names with "dm_", adding the DM version to events, prefixing the table hashes in the ima log with the hash algorithm etc. There are warnings reported by 'make htmldocs' on dm-ima.rst, which need to be fixed. And lastly, the expected behavior needs to be documented when the configuration CONFIG_IMA_DISABLE_HTABLE is disabled. Update the documentation to add examples for 'cache', 'integrity', 'multipath', and 'snapshot' targets. Add the grammar for various DM events and targets in Backus Naur form, so that the attestation servers can interpret and act on the ima measurements for DM target. Fix htmldocs warnings in dm-ima.rst. Update the documentation to be consistent with the code changes that are part of this patch series.

dm init: add dm-mod.waitfor to wait for asynchronously probed block devices Just calling wait_for_device_probe() is not enough to ensure that asynchronously probed block devices are available (E.G. mmc, usb), so add a "dm-mod.waitfor=<device1>[,..,<deviceN>]" parameter to get dm-init to explicitly wait for specific block devices before initializing the tables with logic similar to the rootwait logic that was introduced with commit cc1ed7542c8c ("init: wait for asynchronously scanned block devices").
