2014-06-19stop complaining about unknown kernel cmdline optionsLennart Poettering
Also stop warning about unknown kernel cmdline options in the various tools, not just in PID 1
2014-06-19man: add new kernel command line switches to kernel-command-line(7)Lennart Poettering

2014-06-19main: don't show help text anymore when we detect an unknown kernel cmdline ↵Lennart Poettering
value starting with "systemd." As generators and other components started to maintain their own kernel command line options this help text needed more and more exceptions and wasn't complete anyway. Fixing that would leak more information about specific generators into PID 1, which we should avoid. Given that kernel cmdline handling traditionally doesn't generate errors or show help texts, let's just remove the logic for it for systemd too.

debug-generator can mask specific units if they are specified on the kernel command line with systemd.mask=. debug-generator can pull in debug-shell.service is systemd.debug-shell is passed on the kernel command line.
2014-06-19sd-dhcp6-client: Initialize fd to -1 and rename functionZbigniew Jędrzejewski-Szmek
client_initialize name is misleading, since the function is actually useful at the *end*, to reinitialize the object. But reset is shorter, so rename it to client_reset.

2014-06-19networkd: Add initial DHCPv6 supportPatrik Flykt
Enable DHCPv6 support by creating a DHCPv6 boolean in the Network section. Add necessary DHCPv6 structures and initial function calls.
2014-06-19sd-dhcp6-client: Add reply sending for testPatrik Flykt
Enhance the test case by generating a Reply. With a properly formed Reply the callback function will be called and the additional earlier event loop exit can now be removed.
2014-06-19sd-dhcp6-client: Receive and parse a reply and set T1 and T2 timersPatrik Flykt
Receive and parse a Reply from the server. Set up T1 and T2 timers and notify the library user of an acquired DHCPv6 lease.
2014-06-19sd-dhcp6-client: Add Advertise sending for test casePatrik Flykt
Enhance the test case by replying with an Advertise message to the client. Copy the transaction id, IAID and DUID from the Solicit message. Verify the Request message created by the DHCPv6 client implementation and move the main loop exit to the end of the Request message verification.
2014-06-19sd-dhcp6-client: Add Request message sendingPatrik Flykt
As described in RFC 3315, Section 17.1.2, a client has to wait until the first timeout has elapsed before it is allowed to request IPv6 addresses from the DHCPv6 server. This is indicated by a non-NULL lease and a non-zero resend count. Should the Advertisement contain a preference value of 255 or be received after the first timeout, IPv6 address requesting is started immediately. In response to these events, create a Request message and set up proper resend timers to send the message to the server.
2014-06-19sd-dhcp6-client: Update start function to take a statePatrik Flykt
Update the start function so that the client state can be conveniently changed with the previous message resend timers cleared. On initial startup also create and bind to the UDP socket.
2014-06-19sd-dhcp6-client: Add test case for Advertise message parsingPatrik Flykt
Add a basic test case excersising once more option parsing function in addition to lease handling. Check that the address iteration functions return the correct IPv6 address and lifetimes and that only one address is returned. Also verify that the server ID and preference values are read correctly.
2014-06-19sd-dhcp6-lease: Add functions for accessing lease and addressesPatrik Flykt
Add support functions for accessing the current client lease as well as iterating over the addresses and get their preferred and valid lifetimes.
2014-06-19sd-dhcp6-client: Receive and parse Advertise messagesPatrik Flykt
When receiving DHCPv6 messages, discard the ones that are not meant for DHCPv6 clients and verify the transaction id. Once that is done, process the Advertise message and select the Advertise with the highest preference. Create a separate function for lease information parsing so that it can be reused in other parts of the protocol. Verify both DUID and IAID in the received message and store other necessary information with the lease structure.
2014-06-19sd-dhcp6-client: Add IA Address option parsingPatrik Flykt
Add functionality to parse DHCPv6 Identity Association for Non-temporary (IA_NA) and Temporary Addresses (IA_TA) options. Both of them contain one or more IA Address (IAADDR) options and optinally a status code option. Only the IA_NA option contains lease lifetimes. See RFC 3315, sections 22.4., 22.5., 22.6., 22.13. and appendix B. for details. If the lease timeouts are not set, use the ones recommended for servers in section 22.4. Factor out common code in the form of an option header parsing helper function.
2014-06-19sd-dhcp6-lease: Add DHCPv6 lease handlingPatrik Flykt
Create a structure describing a DHCPv6 lease. Add internal functions for creating a new lease and accessing the server ID, preference and IAID. Provide functions for clearing addresses and associated timers. External users are initially given only the capabilities of referencing and unreferencing the lease structure.
2014-06-19sd-dhcp6-client: Add DHCPv6 Solicit test casePatrik Flykt
Verify the Solicit message created by the DHCPv6 client code. Provide local variants for detect_vm(), detect_container() and detect_virtualization() defined in virt.h. This makes the DHCPv6 library believe it is run in a container and does not try to request interface information from udev for the non-existing interface index used by the test case code.
2014-06-19sd-dhcp6-client: Add DHCPv6 Solicit message creation and sendingPatrik Flykt
Implement the initial functionality used for creating a DHCPv6 Solicit message containing the needed options and send it to the DHCPv6 broadcast address. Increase the sent message count and ensure that the Solicit Initial Retransmission Time is strictly greater than the Solicitation IRT as described in RFC 3315, section 17.1.2.
2014-06-19sd-dhcp6-client: Add functions to bind to DHCPv6 UDP socketPatrik Flykt
Add a function that creates a UDP socket bound to the given interface and optionally to an IPv6 address. Add another function that will send the DHCPv6 UDP packet to its destination. Using IPV6_PKTINFO in setsockopt to bind the IPv6 socket to an interface is documented in section 4. of RFC 3542, "Advanced Sockets Application Program Interface (API) for IPv6" Add a define for DHCPv6 Relay Agents and Servers multicast address as its not available elsewhere.
2014-06-19sd-dhcp6-client: Add basic DHCPv6 option handlingPatrik Flykt
Add option appending and parsing. DHCPv6 options are not aligned, thus the option handling code must be able to handle options starting at any byte boundary. Add a test case for the basic option handling.
2014-06-19sd-dhcp6-client: Add DHCPv6 client Solicitation timeout handlingPatrik Flykt
Add the core of DHCPv6 client message retransmission and upper bound timer and message count handling according to RFC 3315 Secions 7.1.2 and 14. Omit the DHCPv6 initial delay; for now it is assumed that systemd-networkd will provide decent startup randomization that will desynchronize the clients. When reinitializing the client, clear all timers.
2014-06-19sd-dhcp6-client: Add basic DHCPv6 test casesPatrik Flykt
Add test cases for basic DHCPv6 client handling, e.g. setting interface index, mac address and attaching event loop.
2014-06-19sd-dhcp6-client: Add DHCPv6 IAID functionalityPatrik Flykt
Create structures describing Identity Association IDentifiers and IPv6 lease addresses. [tomegun: initialize the IAID when client is started. Base this off of the predictable udev names, if available, as these satisfy the requirement of the IAID, and base it off the mac addres otherwise, as that is the best we have.]
2014-06-19network-internal: split out net_get_name()Tom Gundersen
2014-06-19sd-dhcp6-client: Initialize DUIDTom Gundersen
Initialize DHCP Unique Identifier when creating the client. The DUID is generated based on the machine-id, which satisfies all the requirements of what an DUID should be. The DUID type is DUID-EN. Based on patch by Patrik Flykt.
2014-06-19sd-icmp6-nd: Add initial Router Advertisement test casePatrik Flykt
Feed a Router Advertisement to the code and expect proper events each time. The sending part is ignored, as all of it is static code in the real dhcp_network_icmp6_send_rs() function.
2014-06-19sd-icmp6-nd: Add Router Solicitation and Advertisement supportPatrik Flykt
Provide functions to bind the ICMPv6 socket to the approriate interface and set multicast sending and receiving according to RFC 3493, section 5.2. and RFC 3542, sections 3. and 3.3. Filter out all ICMPv6 messages except Router Advertisements for the socket in question according to RFC 3542, section 3.2. Send Router Solicitations to the all routers multicast group as described in RFC 4861, section 6. and act on the received Router Advertisments according to section 6.3.7. Implement a similar API for ICMPv6 handling as is done for DHCPv4 and DHCPv6.
2014-06-19sd-dhcp6-client: Add initial DHCPv6 client filesPatrik Flykt
Add initial structure definition and functions for setting index, MAC address, callback and event loop. Define protocol values and states.

2014-06-19journald: make SplitMode=uid the defaultLennart Poettering
Now that we actually can distuingish system and normal users there's no point in taking session information into account anymore when splitting up logs. This has the beenfit with that coredump information will actually end up in each user's own journal.

2014-06-19coredumpctl: introduce new -1 switch for showing a single, most recent entry ↵Lennart Poettering
only "coredumpctl info -1" is now incredibly useful for showing the most recent stacktrace.
2014-06-19coredump: simplify how we apply extended attributes to coredumpsLennart Poettering
2014-06-19coredump: include stacktrace of coredumps in the log messageLennart Poettering
elfutils' libdw is maintained, can read DWARF debug data and appears to be the library of choice for generating backtraces today.
2014-06-19bootchart: add assertThomas Hindoe Paaboel Andersen
since 376cd3b89c62f580a6f576cecfbbb28d3944118f LIST_FIND_TAIL accepts an empty list. That removed an assert in LIST_FIND_TAIL and we now theoretically risk a null pointer deref. This adds the assert directly to protect against that.
2014-06-19coredump: add 3 more metadata fields to coredump entriesLennart Poettering

2014-06-19coredump: optionally store coredumps on disk, not in the journalLennart Poettering
Introduce a new configuration file /etc/systemd/coredump.conf to configure when to place coredumps in the journal and when on disk. Since the coredumps are quite large, default to storing them only on disk.
