RaimoNiskanen/raimo/getifaddrs-netns/ERIERL-189/OTP-15121 Implement {netns,NS} option for inet:getifaddrs/1 and friends
2018-10-11Add nopush TCP socket optionIgor Slepchin
This translates to TCP_CORK on Linux and TCP_NOPUSH on BSD. In effect, this acts as super-Nagle: no partial TCP segments are sent out until this option is turned off. Once turned off, all accumulated unsent data is sent out immediately. The latter is *not* the case on OSX, hence the implementation ignores "nopush" on OSX to reduce confusion.
2018-10-03[logger] Add handler callback filter_config/1Siri Hansen
This function is called when a logger API function for fetching handler configuration is called. The point is to allow the handler to remove internal data fields that it might have stored in the configuration database, before returning the handler configuration to the caller. An example of such internal data are the 'handler_pid' and 'mode_tab' fields that logger_std_h and logger_disk_log_h store in their configuration maps.
2018-10-03[logger] Start using handler callback changing_config/3 in built-in handlersSiri Hansen
The new parameter to this function, SetOrUpdate, indicates how unspecified configuration data fields shall be set. The rule is that if SetOrUpdate equals set, then default values shall be used, and if SetOrUpdate equals update, then existing configuration values shall be used. Consequently, these examples now apply to logger_std_h and logger_disk_log_h: set_handler_config(default, config, #{sync_mode_qlen => 20}) sets the value of sync_mode_qlen to 20, and resets all other (writable) fields in the config map to their default values. update_handler_config(default, config, #{sync_mode_qlen => 20}) sets the value of sync_mode_qlen to 20, and leaves all other fields in the config map unchanged.
2018-10-03[logger] Add update_handler_config/3Siri Hansen
This function is similar to set_handler_config/3, but calls the handler callback changing_config/3 with the first parameter SetOrUpdate=update.
2018-10-02Implement {netns,NS} option for inet:getifaddrs/1Raimo Niskanen
Also implement the same option for the legacy undocumented functions inet:getif/1,getiflist/1,ifget/2,ifset/2. The arity 1 functions had before this change got signatures that took a socket port that was used to do the needed syscall, so now the signature was extended to also take an option list with the only supported option {netns,Namespace}. The Socket argument variant remains unsupported. For inet:getifaddrs/1 the documentation file was changed to old style function name definition so be able to hide the Socket argument variant that is visible in the type spec. The arity 2 functions had got an option list as second argument. This list had to be partitioned into one list for the namespace option(s) and the other for the rest. The namespace option list was then fed to the already existing namespace support for socket opening, which places the socket in a namespace and hence made all these functions that in inet_drv.c used getsockopt() work without change. The functions that used getifaddrs() in inet_drv.c had to be changed in inet_drv.c to swap namespaces around the getifaddrs() syscall. This functionality was separated into a new function call_getifaddrs().

2018-09-20[logger] Add SetOrUpdate parameter to handler callback changing_configSiri Hansen
Since logger has now knowledge of the handler specific data ('config' field in the handler configuration map), it can not merge this data structure with default or old values upon configuration change. Instead, the handler callback changing_config must do this. Earlier, this callback did not reflect if the configuration change was initiated by a call to set_handler_config or update_handler_config, so the handler did not know if unspecified fields should get default values or the values from the existing configuration. To overcome this problem, the new parameter SetOrUpdate is added to this callback. If SetOrUpdate equals set, then default values should be used. If SetOrUpdate equals update, then existing configuration values should be used.

2018-09-12[logger] Include single_line option to report_cbSiri Hansen
If the report callback function has two arguments, the second argument is a map with options to limit the size of the log event. To even allow a better formatting when the event shall be printed on a single line, the new option single_line is now included in this argument.

2018-09-12[logger] Update doc about file options in logger_std_hSiri Hansen
2018-09-12[logger] Remove encoding option from logger_formatterSiri Hansen
The encoding option was introduced in commit 270d909696a753af022df72a404c73f2895b4a02, to allow report callbacks to format according to a given encoding. There was, however, no connection between this encoding option, and the encoding of the device to which the logger handler was writing. Since a formatter is defined to return unicode:chardata(), and in order to avoid mismatch with the encoding of the device, the encoding option is now removed from the formatter. The handler itself must make sure that it does not write illegal data to its device.

2018-09-04Implement socket option recvtos and friendsRaimo Niskanen
Implement socket options recvtclass, recvtos, recvttl and pktoptions. Document the implemented socket options, new types and message formats. The options recvtclass, recvtos and recvttl are boolean options that when activated (true) for a socket will cause ancillary data to be received through recvmsg(). That is for packet oriented sockets (UDP and SCTP). The required options for this feature were recvtclass and recvtos, and recvttl was only added to test that the ancillary data parsing handled multiple data items in one message correctly. These options does not work on Windows since ancillary data is not handled by the Winsock2 API. For stream sockets (TCP) there is no clear connection between a received packet and what is returned when reading data from the socket, so recvmsg() is not useful. It is possible to get the same ancillary data through a getsockopt() call with the IPv6 socket option IPV6_PKTOPTIONS, on Linux named IPV6_2292PKTOPTIONS after the now obsoleted RFC where it originated. (unfortunately RFC 3542 that obsoletes it explicitly undefines this way to get packet ancillary data from a stream socket) Linux also has got a way to get packet ancillary data for IPv4 TCP sockets through a getsockopt() call with IP_PKTOPTIONS, which appears to be Linux specific. This implementation uses a flag field in the inet_drv.c socket internal data that records if any setsockopt() call with recvtclass, recvtos or recvttl (IPV6_RECVTCLASS, IP_RECVTOS or IP_RECVTTL) has been activated. If so recvmsg() is used instead of recvfrom(). Ancillary data is delivered to the application by a new return tuple format from gen_udp:recv/2,3 containing a list of ancillary data tuples [{tclass,TCLASS} | {tos,TOS} | {ttl,TTL}], as returned by recvmsg(). For a socket in active mode a new message format, containing the ancillary data list, delivers the data in the same way. For gen_sctp the ancillary data is delivered in the same way, except that the gen_sctp return tuple format already contained an ancillary data list so there are just more possible elements when using these socket options. Note that the active mode message format has got an extra tuple level for the ancillary data compared to what is now implemented gen_udp. The gen_sctp active mode format was considered to be the odd one - now all tuples containing ancillary data are flat, except for gen_sctp active mode. Note that testing has not shown that Linux SCTP sockets deliver any ancillary data for these socket options, so it is probably not implemented yet. Remains to be seen what FreeBSD does... For gen_tcp inet:getopts([pktoptions]) will deliver the latest received ancillary data for any activated socket option recvtclass, recvtos or recvttl, on platforms where IP_PKTOPTIONS is defined for an IPv4 socket, or where IPV6_PKTOPTIONS or IPV6_2292PKTOPTIONS is defined for an IPv6 socket. It will be delivered as a list of ancillary data items in the same way as for gen_udp (and gen_sctp). On some platforms, e.g the BSD:s, when you activate IP_RECVTOS you get ancillary data tagged IP_RECVTOS with the TOS value, but on Linux you get ancillary data tagged IP_TOS with the TOS value. Linux follows the style of RFC 2292, and the BSD:s use an older notion. For RFC 2292 that defines the IP_PKTOPTIONS socket option it is more logical to tag the items with the tag that is the item's, than with the tag that defines that you want the item. Therefore this implementation translates all BSD style ancillary data tags to the corresponding Linux style data tags, so the application will only see the tags 'tclass', 'tos' and 'ttl' on all platforms.

If the report callback is a fun of arity 2, then the second argument is a map with the keys 'encoding', 'depth' and 'chars_limit', and the fun must return a string which is size limited according to the given depth and chars_limit. If the report callback is a fun of arity 1, then it must return a tuple containing a format string and a list of arguments. The formatter will produce the string, and limit it's size.
