The kernel component implements the API defined * in dm-dirty-log.h. Its purpose is simply to pass the parameters and * return values of those API functions between kernel and user-space. * * Below are defined the 'request_types' - DM_ULOG_CTR, DM_ULOG_DTR, etc. * These request types represent the different functions in the device-mapper * dirty log API. Each of these is described in more detail below. * * The user-space program must listen for requests from the kernel (representing * the various API functions) and process them. * * User-space begins by setting up the communication link (error checking * removed for clarity): * fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR); * addr.nl_family = AF_NETLINK; * addr.nl_groups = CN_IDX_DM; * addr.nl_pid = 0; * r = bind(fd, (struct sockaddr *) &addr, sizeof(addr)); * opt = addr.nl_groups; * setsockopt(fd, SOL_NETLINK, NETLINK_ADD_MEMBERSHIP, &opt, sizeof(opt)); * * User-space will then wait to receive requests form the kernel, which it * will process as described below. The requests are received in the form, * ((struct dm_ulog_request) + (additional data)). Depending on the request * type, there may or may not be 'additional data'. In the descriptions below, * you will see 'Payload-to-userspace' and 'Payload-to-kernel'. The * 'Payload-to-userspace' is what the kernel sends in 'additional data' as * necessary parameters to complete the request. The 'Payload-to-kernel' is * the 'additional data' returned to the kernel that contains the necessary * results of the request. The 'data_size' field in the dm_ulog_request * structure denotes the availability and amount of payload data. */ /* * DM_ULOG_CTR corresponds to (found in dm-dirty-log.h): * int (*ctr)(struct dm_dirty_log *log, struct dm_target *ti, * unsigned argc, char **argv); * * Payload-to-userspace: * A single string containing all the argv arguments separated by ' 's * Payload-to-kernel: * A NUL-terminated string that is the name of the device that is used * as the backing store for the log data.

If there is no device needed * for log data, 'data_size' in the dm_ulog_request struct should be 0. * * The UUID contained in the dm_ulog_request structure is the reference that * will be used by all request types to a specific log.
