* MACROS:
config: add CFG_DEFAULT_RUN_TIME for config options with runtime defaults Previously, we declared a default value as undefined ("NULL") for settings which require runtime context to be set first (e.g. settings for paths that rely on SYSTEM_DIR environment variable or they depend on any other setting in some way). If we want to output default values as they are really used in runtime, we should make it possible to define a default value as function which is evaluated, not just providing a firm constant value as it was before. This patch defines simple prototypes for such functions. Also, there's new helper macros "cfg_runtime" and "cfg_array_runtime" - they provide exactly the same functionality as the original "cfg" and "cfg_array" macros when defining the configuration settings in config_settings.h, but they don't set the constant default value. Instead, they automatically link the configuration setting definition with one of these functions: typedef int (*t_fn_CFG_TYPE_BOOL) (struct cmd_context *cmd, struct profile *profile); typedef int (*t_fn_CFG_TYPE_INT) (struct cmd_context *cmd, struct profile *profile); typedef float (*t_fn_CFG_TYPE_FLOAT) (struct cmd_context *cmd, struct profile *profile); typedef const char* (*t_fn_CFG_TYPE_STRING) (struct cmd_context *cmd, struct profile *profile); typedef const char* (*t_fn_CFG_TYPE_ARRAY) (struct cmd_context *cmd, struct profile *profile); (The new macros actually set the CFG_DEFAULT_RUNTIME flag properly and set the default value link to the function accordingly). Then such configuration setting requires a function of selected type to be defined. This function has a predefined name: get_default_<id> ...where the <id> is the id of the setting as defined in config_settings.h. For example "backup_archive_dir_CFG" if defined as a setting with default value evaluated in runtime with "cfg_runtime" will automatically have "get_default_backup_archive_dir_CFG" function linked to this setting to get the default value.

*
* - define a configuration array of one or more types:

*
* If default value can't be assigned statically because it depends on some
* run-time checks or if it depends on other settings already defined,
* the configuration setting or array can be defined with the
* "{cfg|cfg_array}_runtime" macro. In this case the default value
* is evaluated by automatically calling "get_default_<id>" function.

config: add validation for configuration profiles Besides the classical configuration checks (type checking and checking whether the item is recognized by lvm tools) for profiles, do an extra check whether the configuration setting is customizable by a profile at all. Give a warning message if not.

dumpconfig: comment out config lines without default values defined To make "lvm dumpconfig --type default" output to be usable like any other config, we need to comment out lines that have no default value defined. Otherwise, we'd have the output with config options with blank or zero values which is not the same as when the value is not defined! And such configuration can't be feed into lvm again without further edits. So let's fix this.

config: use config checks and add support for creating trees from config definition (config_def_create_tree fn) Configuration checking is initiated during config load/processing (_process_config fn) which is part of the command context creation/refresh. This patch also defines 5 types of trees that could be created from the configuration definition (config_settings.h), the cfg_def_tree_t: - CFG_DEF_TREE_CURRENT that denotes a tree of all the configuration nodes that are explicitly defined in lvm.conf/--config - CFG_DEF_TREE_MISSING that denotes a tree of all missing configuration nodes for which default valus are used since they're not explicitly used in lvm.conf/--config - CFG_DEF_TREE_DEFAULT that denotes a tree of all possible configuration nodes with default values assigned, no matter what the actual lvm.conf/--config is - CFG_DEF_TREE_NEW that denotes a tree of all new configuration nodes that appeared in given version - CFG_DEF_TREE_COMPLETE that denotes a tree of the whole configuration tree that is used in LVM2 (a combination of CFG_DEF_TREE_CURRENT + CFG_DEF_TREE_MISSING). This is not implemented yet, it will be added later... The function that creates the definition tree of given type: struct dm_config_tree *config_def_create_tree(struct config_def_tree_spec *spec); Where the "spec" specifies the tree type to be created: struct config_def_tree_spec { cfg_def_tree_t type; /* tree type */ uint16_t version; /* tree at this LVM2 version */ int ignoreadvanced; /* do not include advanced configs */ int ignoreunsupported; /* do not include unsupported configs */ }; This tree can be passed to already existing functions that write the tree on output (like we already do with cmd->cft). There is a new lvm.conf section called "config" with two new options: - config/checks which enables/disables checking (enabled by default) - config/abort_on_errors which enables/disables aborts on any type of mismatch found in the config (disabled by default)

Also, the lvm dumpconfig can show proper and exact information about this setting then (the variant that shows default values).

Mirror: Fix hangs and lock-ups caused by attempting label reads of mirrors There is a problem with the way mirrors have been designed to handle failures that is resulting in stuck LVM processes and hung I/O. When mirrors encounter a write failure, they block I/O and notify userspace to reconfigure the mirror to remove failed devices. This process is open to a couple races: 1) Any LVM process other than the one that is meant to deal with the mirror failure can attempt to read the mirror, fail, and block other LVM commands (including the repair command) from proceeding due to holding a lock on the volume group. 2) If there are multiple mirrors that suffer a failure in the same volume group, a repair can block while attempting to read the LVM label from one mirror while trying to repair the other. Mitigation of these races has been attempted by disallowing label reading of mirrors that are either suspended or are indicated as blocking by the kernel. While this has closed the window of opportunity for hitting the above problems considerably, it hasn't closed it completely. This is because it is still possible to start an LVM command, read the status of the mirror as healthy, and then perform the read for the label at the moment after a the failure is discovered by the kernel. I can see two solutions to this problem: 1) Allow users to configure whether mirrors can be candidates for LVM labels (i.e. whether PVs can be created on mirror LVs). If the user chooses to allow label scanning of mirror LVs, it will be at the expense of a possible hang in I/O or LVM processes. 2) Instrument a way to allow asynchronous label reading - allowing blocked label reads to be ignored while continuing to process the LVM command. This would action would allow LVM commands to continue even though they would have otherwise blocked trying to read a mirror. They can then release their lock and allow a repair command to commence. In the event of #2 above, the repair command already in progress can continue and repair the failed mirror. This patch brings solution #1. If solution #2 is developed later on, the configuration option created in #1 can be negated - allowing mirrors to be scanned for labels by default once again.

dumpconfig: comment out config lines without default values defined To make "lvm dumpconfig --type default" output to be usable like any other config, we need to comment out lines that have no default value defined. Otherwise, we'd have the output with config options with blank or zero values which is not the same as when the value is not defined!

dumpconfig: comment out config lines without default values defined To make "lvm dumpconfig --type default" output to be usable like any other config, we need to comment out lines that have no default value defined. Otherwise, we'd have the output with config options with blank or zero values which is not the same as when the value is not defined! And such configuration can't be feed into lvm again without further edits. So let's fix this.

fix: apply profile and then get the config path + auto_set_activation not profilable cfg_def_get_path uses a global static var to store the result (for efficiency). So we need to apply the profile first and then get the path for the config item when calling find_config_tree_* fns. Also activation/auto_set_activation is not profilable (at least not now, maybe later if we need that).

config: fix metadata/disk_areas config setting registration The metadata/disk_areas setting was incorrectly registered as "string" configuration option but it's a section where each area is defined in its own subsection with "start_sector", "size" and "id" setting. This setting is not officialy supported, it's undocumented and it's used solely for debugging. Note: At this moment, it does not seem to be working with lvmetad!
