-# Contribution guidelines
-
-Thanks for taking the time to contribute to the [collectd
-project](https://collectd.org/)! This document tries to give some guidance to
-make the process of contributing to *collectd* as pleasant as possible.
-
-## Bug reports
-
-Please report bugs as [GitHub
-Issues](https://github.com/collectd/collectd/issues). Try to answer the
-following questions:
-
-* Which version of *collectd* are you using?
-* Which operating system (distribution) are you using at which version?
-* What is the expected behavior / output?
-* What is the actual (observed) behavior / output?
-* How can we reproduce the problem you're having?
-* If *collectd* crashes, try to get a
- [stack trace](https://collectd.org/wiki/index.php/Core_file).
-
-Please monitor your issue for a couple of days and reply to questions. To keep
-the project manageable, we have to do some housekeeping; meaning we will close
-issues that have become stale.
-
-## Code contributions
-
-Please open a [GitHub Pull Request](https://github.com/collectd/collectd/pulls)
-(PR) to contribute bug fixes, features, cleanups, new plugins, … Patches sent to
-the mailing list have a tendency to fall through the cracks.
-
-* *Focus:* Fix *one thing* in your PR. The smaller your change, the faster it
- will be reviewed and merged.
-* *Coding style:* Please run `clang-format -style=file -i $FILE` after editing
- `.c`, `.h` and `.proto` files. If you don't want to install *clang-format*
- locally or your version produces a different result than the formatting
- check on Github, use `contrib/format.sh` to format files using the same web
- service used by our check.
-* *Documentation:* New config options need to be documented in two places: the
- manpage (`src/collectd.conf.pod`) and the example config
- (`src/collectd.conf.in`). New plugins need to be added to the `README` file.
-* *Continuous integration:* Once your PR is created, our continuous
- integration environment will try to build it on a number of platforms. If
- this reports a failure, please investigate and fix the problem. We will at
- best do a very casual review for failing PRs.
-* *Don't rebase:* Rebasing your branch destroys the review history. If a review
- takes a long time, we may ask you to rebase on a more recent *master*, but
- please don't do it without being asked.
-* *types.db:* One of the most common mistakes made by new contributors is the
- addition of (many) new *types* in the file `src/types.db`. The majority of
- usecases can be met with one of the existing entries. If you plan to add new
- entries to `src/types.db`, you should talk to us early in the design
- process.

+# Contribution guidelines
+
+Thanks for taking the time to contribute to the [collectd
+project](https://collectd.org/)! This document tries to give some guidance to
+make the process of contributing to *collectd* as pleasant as possible.
+
+## Bug reports
+
+Please report bugs as [GitHub
+Issues](https://github.com/collectd/collectd/issues). Try to answer the
+following questions:
+
+* Which version of *collectd* are you using?
+* Which operating system (distribution) are you using at which version?
+* What is the expected behavior / output?
+* What is the actual (observed) behavior / output?
+* How can we reproduce the problem you're having?
+* If *collectd* crashes, try to get a
+ [stack trace](https://collectd.org/wiki/index.php/Core_file).
+
+Please monitor your issue for a couple of days and reply to questions. To keep
+the project manageable, we have to do some housekeeping; meaning we will close
+issues that have become stale.
+
+## Code contributions
+
+Please open a [GitHub Pull Request](https://github.com/collectd/collectd/pulls)
+(PR) to contribute bug fixes, features, cleanups, new plugins, … Patches sent to
+the mailing list have a tendency to fall through the cracks.
+
+* *Focus:* Fix *one thing* in your PR. The smaller your change, the faster it
+ will be reviewed and merged.
+* *Coding style:* Please run `clang-format -style=file -i $FILE` after editing
+ `.c`, `.h` and `.proto` files. If you don't want to install *clang-format*
+ locally or your version produces a different result than the formatting
+ check on Github, use `contrib/format.sh` to format files using the same web
+ service used by our check.
+* *Documentation:* New config options need to be documented in two places: the
+ manpage (`src/collectd.conf.pod`) and the example config
+ (`src/collectd.conf.in`). New plugins need to be added to the `README` file.
+* *Continuous integration:* Once your PR is created, our continuous
+ integration environment will try to build it on a number of platforms. If
+ this reports a failure, please investigate and fix the problem. We will at
+ best do a very casual review for failing PRs.
+* *Don't rebase:* Rebasing your branch destroys the review history. If a
+ review takes a long time, we may ask you to rebase on a more recent
+ *master*, but please don't do that without being asked.
+* *types.db:* One of the most common mistakes made by new contributors is the
+ addition of (many) new *types* in the file `src/types.db`. The majority of
+ usecases can be met with one of the existing entries. If you plan to add new
+ entries to `src/types.db`, you should talk to us early in the design
+ process.
+
+### ChangeLog
+
+PRs need to have a one-line summary in the *PR description*. This information
+is used to automatically generate release notes. If you got here after creating
+the PR, you need to go to the *PR description* (shown as the first "comment" on
+the PR, made by yourself) and *edit* that description. Editing a PR will
+trigger the "ChangeLog" status to be updated.
+
+For the summary itself, follow this style:
+
+```
+ChangeLog: Foo plugin: A specific issue people had has been fixed.
+```
+
+The summary must be on a line of its own, with a "ChangeLog:" prefix at the
+beginning of the line. The text should start with "Foo plugin" to give the
+reader context for the information. Other common contexts are "collectd" for
+the core daemon, "Build system", and "Documentation". Use past tense and
+passive voice the for remainder, e.g. "a bug has been fixed", "a feature has
+been added".
+
+Some PRs should be excluded from the release notes, e.g. changes to project
+internal documentation (such as this file). Those changes are not interesting
+for external users of the project and would reduce the value of the release
+notes. Maintainers may use the `Unlisted Change` label to mark those PRs.

-Because querying a host via SNMP may produce a timeout multiple threads are
-used to query hosts in parallel. Depending on the number of hosts between one
-and ten threads are used.
+Because querying a host via SNMP may produce a timeout the "complex reads"
+polling method is used. The ReadThreads parameter in the main configuration
+influences the number of parallel polling jobs which can be undertaken. If
+you expect timeouts or some polling to take a long time, you should increase
+this parameter. Note that other plugins also use the same threads.

B<Note:> By default global interval is used to retrieve statistics on monitored
For Modbus/RTU, specifies the baud rate of the serial device.
Note, connections currently support only 8/N/1.
+=item B<UARTType> I<UARTType>
+
+For Modbus/RTU, specifies the type of the serial device.
+RS232, RS422 and RS485 are supported. Defaults to RS232.
+Available only on Linux systems with libmodbus>=2.9.4.
+
=item B<Interval> I<Interval>
Sets the interval (in seconds) in which the values will be collected from this
namely octets, packets, and errors. These statistics are collected by
the C<interface> plugin, too, so using both at the same time is no benefit.
-When configured with B<VerboseInterface> all counters B<except> the basic ones,
-so that no data needs to be collected twice if you use the C<interface> plugin.
+When configured with B<VerboseInterface> all counters B<except> the basic ones
+will be collected, so that no data needs to be collected twice if you use the
+C<interface> plugin.
This includes dropped packets, received multicast packets, collisions and a
whole zoo of differentiated RX and TX errors. You can try the following command
to get an idea of what awaits you:
Address "127.0.0.1"
Socket "/var/run/openvswitch/db.sock"
Bridges "br0" "br_ext"
+ InterfaceStats false
</Plugin>
The plugin provides the following configuration options:
Default: empty (monitor all bridges)
+=item B<InterfaceStats> B<false>|B<true>
+
+Indicates that the plugin should gather statistics for individual interfaces
+in addition to ports. This can be useful when monitoring an OVS setup with
+bond ports, where you might wish to know individual statistics for the
+interfaces included in the bonds. Defaults to B<false>.

=item B<GaugeAverage>
-Calculate the average.
+Calculate the average of all values matched during the interval.
=item B<GaugeMin>
-Use the smallest number only.
+Report the smallest value matched during the interval.
=item B<GaugeMax>
-Use the greatest number only.
+Report the greatest value matched during the interval.
=item B<GaugeLast>
-Use the last number found.
+Report the last value matched during the interval.
=item B<GaugePersist>
-Use the last number found. The number is not reset at the end of an interval.
-It is continously reported until another number is matched. This is intended
-for cases in which only state changes are reported, for example a thermometer
-that only reports the temperature when it changes.
+Report the last matching value. The metric is I<not> reset to C<NaN> at the end
+of an interval. It is continuously reported until another value is matched.
+This is intended for cases in which only state changes are reported, for
+example a thermometer that only reports the temperature when it changes.
=item B<CounterSet>
not use the matched subexpression, but simply count the number of matched
lines. Thus, you may use a regular expression without submatch in this case.
+B<GaugeInc> is reset to I<zero> after every read, unlike other B<Gauge*>
+metrics which are reset to C<NaN>.
+
=item B<Distribution>
Type to do calculations based on the distribution of values, primarily
point number, using L<strtod(3)>. The B<Counter*> and B<AbsoluteSet> types
interpret the submatch as an unsigned integer using L<strtoull(3)>. The
B<Derive*> types interpret the submatch as a signed integer using
-L<strtoll(3)>. B<CounterInc> and B<DeriveInc> do not use the submatch at all
-and it may be omitted in this case.
+L<strtoll(3)>. B<CounterInc>, B<DeriveInc> and B<GaugeInc> do not use the
+submatch at all and it may be omitted in this case.
+
+The B<Gauge*> types, unless noted otherwise, are reset to C<NaN> after being
+reported. In other words, B<GaugeAverage> reports the average of all values
+matched since the last metric was reported (or C<NaN> if there was no match).
=item B<Type> I<Type>
The default is to collect statistics for all domains and all their devices.
-Example:
+B<Note:> B<BlockDevice> and B<InterfaceDevice> options are related to
+corresponding B<*Format> options. Specifically, B<BlockDevice> filtering depends
+on B<BlockDeviceFormat> setting - if user wants to filter block devices by
+'target' name then B<BlockDeviceFormat> option has to be set to 'target' and
+B<BlockDevice> option must be set to a valid block device target
+name("/:hdb/"). Mixing formats and filter values from different worlds (i.e.,
+using 'target' name as B<BlockDevice> value with B<BlockDeviceFormat> set to
+'source') may lead to unexpected results (all devices filtered out or all
+visible, depending on the value of B<IgnoreSelected> option).
+Similarly, option B<InterfaceDevice> is related to B<InterfaceFormat> setting
+(i.e., when user wants to use MAC address as a filter then B<InterfaceFormat>
+has to be set to 'address' - using wrong type here may filter out all of the
+interfaces).
+
+B<Example 1:>
+
+Ignore all I<hdb> devices on any domain, but other block devices (eg. I<hda>)
+will be collected:
BlockDevice "/:hdb/"
IgnoreSelected "true"
+ BlockDeviceFormat "target"
-Ignore all I<hdb> devices on any domain, but other block devices (eg. I<hda>)
-will be collected.
+B<Example 2:>
+
+Collect metrics only for block device on 'baremetal0' domain when its
+'source' matches given path:
+
+ BlockDevice "baremetal0:/var/lib/libvirt/images/baremetal0.qcow2"
+ BlockDeviceFormat source
+
+As you can see it is possible to filter devices/interfaces using
+various formats - for block devices 'target' or 'source' name can be
+used. Interfaces can be filtered using 'name', 'address' or 'number'.
+
+B<Example 3:>
+
+Collect metrics only for domains 'baremetal0' and 'baremetal1' and
+ignore any other domain:
+
+ Domain "baremetal0"
+ Domain "baremetal1"
+
+It is possible to filter multiple block devices/domains/interfaces by
+adding multiple filtering entries in separate lines.
=item B<BlockDeviceFormat> B<target>|B<source>
Setting C<BlockDeviceFormat source> will cause the I<type instance> to be set
to C<var_lib_libvirt_images_image1.qcow2>.
+B<Note:> this option determines also what field will be used for
+filtering over block devices (filter value in B<BlockDevice>
+will be applied to target or source). More info about filtering
+block devices can be found in the description of B<BlockDevice>.
+
=item B<BlockDeviceFormatBasename> B<false>|B<true>
The B<BlockDeviceFormatBasename> controls whether the full path or the
Setting C<BlockDeviceFormatBasename true> will cause the I<type instance> to be
set to C<image1.qcow2>.
-=item B<HostnameFormat> B<name|uuid|hostname|...>
+=item B<HostnameFormat> B<name|uuid|hostname|metadata...>
When the virt plugin logs data, it sets the hostname of the collected data
according to this setting. The default is to use the guest name as provided by
useful on its own because all guests will appear to have the same name. This is
useful in conjunction with B<PluginInstanceFormat> though.
+B<metadata> means use information from guest's metadata. Use
+B<HostnameMetadataNS> and B<HostnameMetadataXPath> to localize this information.
+
You can also specify combinations of these fields. For example B<name uuid>
means to concatenate the guest name and UUID (with a literal colon character
between, thus I<"foo:1234-1234-1234-1234">).
characters. In case when combination of fields exceeds 62 characters,
hostname will be truncated without a warning.
-=item B<InterfaceFormat> B<name>|B<address>
+=item B<InterfaceFormat> B<name>|B<address>|B<number>
When the virt plugin logs interface data, it sets the name of the collected
data according to this setting. The default is to use the path as provided by
B<address> means use the interface's mac address. This is useful since the
interface path might change between reboots of a guest or across migrations.
-=item B<PluginInstanceFormat> B<name|uuid|none>
+B<number> means use the interface's number in guest.
+
+B<Note:> this option determines also what field will be used for
+filtering over interface device (filter value in B<InterfaceDevice>
+will be applied to name, address or number). More info about filtering
+interfaces can be found in the description of B<InterfaceDevice>.
+
+=item B<PluginInstanceFormat> B<name|uuid|metadata|none>
When the virt plugin logs data, it sets the plugin_instance of the collected
data according to this setting. The default is to not set the plugin_instance.
B<name> means use the guest's name as provided by the hypervisor.
B<uuid> means use the guest's UUID.
+B<metadata> means use information from guest's metadata.
You can also specify combinations of the B<name> and B<uuid> fields.
For example B<name uuid> means to concatenate the guest name and UUID
(with a literal colon character between, thus I<"foo:1234-1234-1234-1234">).
-=item B<Instances> B<integer>
+=item B<HostnameMetadataNS> B<string>
-How many read instances you want to use for this plugin. The default is one,
-and the sensible setting is a multiple of the B<ReadThreads> value.
-If you are not sure, just use the default setting.
+When B<metadata> is used in B<HostnameFormat> or B<PluginInstanceFormat>, this
+selects in which metadata namespace we will pick the hostname. The default is
+I<http://openstack.org/xmlns/libvirt/nova/1.0>.
+
+=item B<HostnameMetadataXPath> B<string>
+
+When B<metadata> is used in B<HostnameFormat> or B<PluginInstanceFormat>, this
+describes where the hostname is located in the libvirt metadata. The default is
+I</instance/name/text()>.
+
+=item B<ReportBlockDevices> B<true>|B<false>
+
+Enabled by default. Allows to disable stats reporting of block devices for
+whole plugin.
+
+=item B<ReportNetworkInterfaces> B<true>|B<false>
+
+Enabled by default. Allows to disable stats reporting of network interfaces for
+whole plugin.
=item B<ExtraStats> B<string>
=item B<vcpupin>: report pinning of domain VCPUs to host physical CPUs.
+=item B<disk_physical>: report 'disk_physical' statistic for disk device.
+B<Note>: This statistic is only reported for disk devices with 'source'
+property available.
+
+=item B<disk_allocation>: report 'disk_allocation' statistic for disk device.
+B<Note>: This statistic is only reported for disk devices with 'source'
+property available.
+
+=item B<disk_capacity>: report 'disk_capacity' statistic for disk device.
+B<Note>: This statistic is only reported for disk devices with 'source'
+property available.
+
=back
=item B<PersistentNotification> B<true>|B<false>
+
Override default configuration to only send notifications when there is a change
in the lifecycle state of a domain. When set to true notifications will be sent
for every read cycle. Default is false. Does not affect the stats being
dispatched.
+=item B<Instances> B<integer>
+
+How many read instances you want to use for this plugin. The default is one,
+and the sensible setting is a multiple of the B<ReadThreads> value.
+
+This option is only useful when domains are specially tagged.
+If you are not sure, just use the default setting.
+
+The reader instance will only query the domains with attached matching tag.
+Tags should have the form of 'virt-X' where X is the reader instance number,
+starting from 0.
+
+The special-purpose reader instance #0, guaranteed to be always present,
+will query all the domains with missing or unrecognized tag, so no domain will
+ever be left out.
+
+Domain tagging is done with a custom attribute in the libvirt domain metadata
+section. Value is selected by an XPath I</domain/metadata/ovirtmap/tag/text()>
+expression in the I<http://ovirt.org/ovirtmap/tag/1.0> namespace.
+(XPath and namespace values are not configurable yet).
+
+Tagging could be used by management applications to evenly spread the
+load among the reader threads, or to pin on the same threads all
+the libvirt domains which use the same shared storage, to minimize
+the disruption in presence of storage outages.

B<Ignorelists> are a generic framework to either ignore some metrics or report
-specific metircs only. Plugins usually provide one or more options to specify
+specific metrics only. Plugins usually provide one or more options to specify

- * `value'. Entries are not returned in any particular order. This function
- * is intended for cache-flushes that don't care about the order but simply
- * want to remove all elements, one at a time.
- *
- * PARAMETERS
- * `t' AVL-tree to get the value from.
- * `key' Pointer to a pointer in which to store the key.
- * `value' Pointer to a pointer in which to store the value.
- *
- * RETURN VALUE
- * Zero upon success or non-zero if the tree is empty or key or value is
- * NULL.

+ * COPYRIGHT (C) 1986 Gary S. Brown. You may use this program, or
+ * code or tables extracted from it, as desired without restriction.
+ *
+ * First, the polynomial itself and its table of feedback terms. The
+ * polynomial is
+ * X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ * Note that we take it "backwards" and put the highest-order term in
+ * the lowest-order bit. The X^32 term is "implied"; the LSB is the
+ * X^31 term, etc. The X^0 term (usually shown as "+1") results in
+ * the MSB being 1
+ *
+ * Note that the usual hardware shift register implementation, which
+ * is what we're using (we're merely optimizing it by doing eight-bit
+ * chunks at a time) shifts bits into the lowest-order term. In our
+ * implementation, that means shifting towards the right. Why do we
+ * do it this way? Because the calculated CRC must be transmitted in
+ * order from highest-order term to lowest-order term. UARTs transmit
+ * characters in order from LSB to MSB. By storing the CRC this way
+ * we hand it to the UART in the order low-byte to high-byte; the UART
+ * sends each low-bit to hight-bit; and the result is transmission bit
+ * by bit from highest- to lowest-order term without requiring any bit
+ * shuffling on our part. Reception works similarly
+ *
+ * The feedback terms table consists of 256, 32-bit entries. Notes
+ *
+ * The table can be generated at runtime if desired; code to do so
+ * is shown later. It might not be obvious, but the feedback
+ * terms simply represent the results of eight shift/xor opera
+ * tions for all combinations of data and CRC register values
+ *
+ * The values must be right-shifted by eight bits by the "updcrc
+ * logic; the shift must be unsigned (bring in zeroes). On some
+ * hardware you could probably optimize the shift in assembler by
+ * using byte-swap instructions

+ * matches, the callback passed in `callback' will be called along with the
+ * pointer `user_pointer'.
+ * The string that's passed to the callback depends on the regular expression:
+ * If the regular expression includes a sub-match, i. e. something like
+ * "value=([0-9][0-9]*)"
+ * then only the submatch (the part in the parenthesis) will be passed to the
+ * callback. If there is no submatch, then the entire string is passed to the
+ * callback.
+ * The optional `excluderegex' allows to exclude the line from the match, if
+ * the excluderegex matches.
+ * When `match_destroy' is called the `user_data' pointer is freed using
+ * the `free_user_data' callback - if it is not NULL.

+ DESCRIPTION
+ The cu_mount_checkoption() function is a replacement of
+ char *hasmntopt(const struct mntent *mnt, const char *opt).
+ In fact hasmntopt() just looks for the first occurrence of the
+ characters at opt in mnt->mnt_opts. cu_mount_checkoption()
+ checks for the *option* keyword in line, starting at the
+ first character of line or after a ','.
+
+ If full is not 0 then also the end of keyword has to match
+ either the end of line or a ',' after keyword.
+
+ RETURN VALUE
+ The cu_mount_checkoption() function returns a pointer into
+ string line if a match of keyword is found. If no match is
+ found cu_mount_checkoption() returns NULL.
+
+ NOTES
+ Do *not* try to free() the pointer which is returned! It is
+ just part of the string line.
+
+ full should be set to 0 when matching options like: rw, quota,
+ noatime. Set full to 1 when matching options like: loop=,
+ gid=, commit=.
+
+ EXAMPLES
+ If line is "rw,usrquota,grpquota", keyword is "quota", NULL
+ will be returned (independend of full).
+
+ If line is "rw,usrquota,grpquota", keyword is "usrquota",
+ a pointer to "usrquota,grpquota" is returned (independend
+ of full).
+
+ If line is "rw,loop=/dev/loop1,quota", keyword is "loop="
+ and full is 0, then a pointer to "loop=/dev/loop1,quota"
+ is returned. If full is not 0 then NULL is returned. But
+ maybe you might want to try cu_mount_getoptionvalue()...
+*/
+
+char *cu_mount_getoptionvalue(char *line, const char *keyword);
+/*
+ DESCRIPTION
+ The cu_mount_getoptionvalue() function can be used to grab
+ a VALUE out of a mount option (line) like:
+ loop=VALUE
+ whereas "loop=" is the keyword.
+
+ RETURN VALUE
+ If the cu_mount_getoptionvalue() function can find the option
+ keyword in line, then memory is allocated for the value of
+ that option and a pointer to that value is returned.
+
+ If the option keyword is not found, cu_mount_getoptionvalue()
+ returns NULL;
+
+ NOTES
+ Internally it calls cu_mount_checkoption(), then it
+ allocates memory for VALUE and returns a pointer to that
+ string. So *do not forget* to free() the memory returned
+ after use!!!

+ * * Recovery mechanism in case of OVS DB connection lost;
+ * * Subscription mechanism to OVS DB table update events
+ * (insert/modify/delete);
+ * * Send custom JSON request to OVS DB (poll table data, etc.)
+ * * Handling of echo request from OVS DB server to verify the
+ * liveness of the connection.
+ * - Provides YAJL helpers functions.
+ *
+ * OVS DB API User Guide:
+ * All OVS DB function/structure names begins from 'ovs_db_*' prefix. To
+ * start using OVS DB API, client (plugin) should initialize the OVS DB
+ * object (`ovs_db_t') by calling `ovs_db_init' function. It initializes
+ * internal data and creates two main workers (threads). The result of the
+ * function is a pointer to new OVS DB object which can be used by other
+ * OVS DB API later and must be released by `ovs_db_destroy' function if
+ * the object isn't needed anymore.
+ * Once OVS DB API is initialized, the `init_cb' callback is called if
+ * the connection to OVS DB has been established. This callback is called
+ * every time the OVS DB is reconnected. So, if the client registers table
+ * update event callbacks or does any other OVS DB setup that can be lost
+ * after OVS DB reconnecting, it should be done in `init_cb' callback.
+ * The `ovs_db_table_cb_register` function is used to register OVS DB
+ * table update event callback and receive the table update notification
+ * when requested event occurs (registered callback is called). See
+ * function API for more info.
+ * To send custom JSON-RPC request to OVS DB, the `ovs_db_send_request'
+ * function is used. Please note, that connection to OVS DB should be
+ * established otherwise the function will return error.
+ * To verify the liveness of established connection, the OVS DB server
+ * sends echo request to the client with a given interval. The OVS utils
+ * takes care about this request and handles it properly.

- * COPYRIGHT (C) 1986 Gary S. Brown. You may use this program, or
- * code or tables extracted from it, as desired without restriction.
- *
- * First, the polynomial itself and its table of feedback terms. The
- * polynomial is
- * X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
- *
- * Note that we take it "backwards" and put the highest-order term in
- * the lowest-order bit. The X^32 term is "implied"; the LSB is the
- * X^31 term, etc. The X^0 term (usually shown as "+1") results in
- * the MSB being 1
- *
- * Note that the usual hardware shift register implementation, which
- * is what we're using (we're merely optimizing it by doing eight-bit
- * chunks at a time) shifts bits into the lowest-order term. In our
- * implementation, that means shifting towards the right. Why do we
- * do it this way? Because the calculated CRC must be transmitted in
- * order from highest-order term to lowest-order term. UARTs transmit
- * characters in order from LSB to MSB. By storing the CRC this way
- * we hand it to the UART in the order low-byte to high-byte; the UART
- * sends each low-bit to hight-bit; and the result is transmission bit
- * by bit from highest- to lowest-order term without requiring any bit
- * shuffling on our part. Reception works similarly
- *
- * The feedback terms table consists of 256, 32-bit entries. Notes
- *
- * The table can be generated at runtime if desired; code to do so
- * is shown later. It might not be obvious, but the feedback
- * terms simply represent the results of eight shift/xor opera
- * tions for all combinations of data and CRC register values
- *
- * The values must be right-shifted by eight bits by the "updcrc
- * logic; the shift must be unsigned (bring in zeroes). On some
- * hardware you could probably optimize the shift in assembler by
- * using byte-swap instructions

- * Define plugin's global pointer variable of type ignorelist_t:

- * If you know the state of the global ignore (IgnoreSelected),
- * allocate the variable with:
- * myconfig_ignore = ignorelist_create (YourKnownIgnore);
- * If you do not know the state of the global ignore,
- * initialize the global variable and set the ignore flag later:
- * myconfig_ignore = ignorelist_init ();
- * Append single entries in your cf_register'ed callback function:
- * ignorelist_add (myconfig_ignore, newentry);
- * When you hit the IgnoreSelected config option,
- * offer it to the list:
- * ignorelist_ignore (myconfig_ignore, instantly_got_value_of_ignore);
- * That is all for the ignorelist initialization.
- * Later during read and write (plugin's registered functions) get
- * the information whether this entry would be collected or not:
- * if (ignorelist_match (myconfig_ignore, thisentry))
- * return;

- *
- * DESCRIPTION
- * Creates a new `cu_match_t' object which will use the regular expression
- * `regex' to match lines, see the `match_apply' method below. If the line
- * matches, the callback passed in `callback' will be called along with the
- * pointer `user_pointer'.
- * The string that's passed to the callback depends on the regular expression:
- * If the regular expression includes a sub-match, i. e. something like
- * "value=([0-9][0-9]*)"
- * then only the submatch (the part in the parenthesis) will be passed to the
- * callback. If there is no submatch, then the entire string is passed to the
- * callback.
- * The optional `excluderegex' allows to exclude the line from the match, if
- * the excluderegex matches.
- * When `match_destroy' is called the `user_data' pointer is freed using
- * the `free_user_data' callback - if it is not NULL.

- * Creates a new `cu_match_t' with a default callback. The user data for that

-

-/*
- DESCRIPTION
- The cu_mount_checkoption() function is a replacement of
- char *hasmntopt(const struct mntent *mnt, const char *opt).
- In fact hasmntopt() just looks for the first occurrence of the
- characters at opt in mnt->mnt_opts. cu_mount_checkoption()
- checks for the *option* keyword in line, starting at the
- first character of line or after a ','.
-
- If full is not 0 then also the end of keyword has to match
- either the end of line or a ',' after keyword.
-
- RETURN VALUE
- The cu_mount_checkoption() function returns a pointer into
- string line if a match of keyword is found. If no match is
- found cu_mount_checkoption() returns NULL.
-
- NOTES
- Do *not* try to free() the pointer which is returned! It is
- just part of the string line.
-
- full should be set to 0 when matching options like: rw, quota,
- noatime. Set full to 1 when matching options like: loop=,
- gid=, commit=.
-
- EXAMPLES
- If line is "rw,usrquota,grpquota", keyword is "quota", NULL
- will be returned (independend of full).
-
- If line is "rw,usrquota,grpquota", keyword is "usrquota",
- a pointer to "usrquota,grpquota" is returned (independend
- of full).
-
- If line is "rw,loop=/dev/loop1,quota", keyword is "loop="
- and full is 0, then a pointer to "loop=/dev/loop1,quota"
- is returned. If full is not 0 then NULL is returned. But
- maybe you might want to try cu_mount_getoptionvalue()...
-*/
-
-char *cu_mount_getoptionvalue(char *line, const char *keyword);
-/*
- DESCRIPTION
- The cu_mount_getoptionvalue() function can be used to grab
- a VALUE out of a mount option (line) like:
- loop=VALUE
- whereas "loop=" is the keyword.
-
- RETURN VALUE
- If the cu_mount_getoptionvalue() function can find the option
- keyword in line, then memory is allocated for the value of
- that option and a pointer to that value is returned.
-
- If the option keyword is not found, cu_mount_getoptionvalue()
- returns NULL;
-
- NOTES
- Internally it calls cu_mount_checkoption(), then it
- allocates memory for VALUE and returns a pointer to that
- string. So *do not forget* to free() the memory returned
- after use!!!

- * Description:
- * The OVS util module provides the following features:
- * - Implements the OVS DB communication transport specified
- * by RFC7047:
- * * Connect/disconnect to OVS DB;
- * * Recovery mechanism in case of OVS DB connection lost;
- * * Subscription mechanism to OVS DB table update events
- * (insert/modify/delete);
- * * Send custom JSON request to OVS DB (poll table data, etc.)
- * * Handling of echo request from OVS DB server to verify the
- * liveness of the connection.
- * - Provides YAJL helpers functions.
- *
- * OVS DB API User Guide:
- * All OVS DB function/structure names begins from 'ovs_db_*' prefix. To
- * start using OVS DB API, client (plugin) should initialize the OVS DB
- * object (`ovs_db_t') by calling `ovs_db_init' function. It initializes
- * internal data and creates two main workers (threads). The result of the
- * function is a pointer to new OVS DB object which can be used by other
- * OVS DB API later and must be released by `ovs_db_destroy' function if
- * the object isn't needed anymore.
- * Once OVS DB API is initialized, the `init_cb' callback is called if
- * the connection to OVS DB has been established. This callback is called
- * every time the OVS DB is reconnected. So, if the client registers table
- * update event callbacks or does any other OVS DB setup that can be lost
- * after OVS DB reconnecting, it should be done in `init_cb' callback.
- * The `ovs_db_table_cb_register` function is used to register OVS DB
- * table update event callback and receive the table update notification
- * when requested event occurs (registered callback is called). See
- * function API for more info.
- * To send custom JSON-RPC request to OVS DB, the `ovs_db_send_request'
- * function is used. Please note, that connection to OVS DB should be
- * established otherwise the function will return error.
- * To verify the liveness of established connection, the OVS DB server
- * sends echo request to the client with a given interval. The OVS utils
- * takes care about this request and handles it properly.
