2014-03-28sd-rtnl: message - don't reference associated rtnl objectTom Gundersen
The object is not currently used, so just drop the refenence. If/when we end up using the object in the future, we must make sure to deal with possible mutual references between rtnl busses and their queued messages; as is done in sd-bus.
2014-03-25sd-rtnl: add support for tunnel attributesSusant Sahani
Added support for tunneling netlink attrributes (ipip, gre, sit). These works with kernel module ipip, gre and sit . The test cases are moved to a separate file and manual test as well because they require respective kernel modules as well.
2014-03-25sd-rtnl: message - don't try to enter unsupported containersTom Gundersen
Currently we only support containers in RTM_*LINK messages. Reported-by: "Thomas H.P. Andersen <phomes@gmail.com>"
2014-03-24networkd: fix a couple of memory leaksLennart Poettering
2014-03-24sd-rtnl: tests - drop redundant testsTom Gundersen
These tests were both broken and redundant, so let's drop them.
2014-03-24sd-rtnl: message parsing - log when ignoring message attributesTom Gundersen
2014-03-24sd-rtnl: add sd_rtnl_message_enter_container()Tom Gundersen
Extend rta_offset_tb into a stack of offset tables, one for each parent of the current container, and make sd_rtnl_message_{enter,exit}_container() pop/push to this stack. Also make sd_rtnl_message_rewind() parse the top-level container, and use this when reading a message from the socket. This changes the API by dropping the now redundant sd_rtnl_message_read() method.
2014-03-24sd-event: rework API to support CLOCK_REALTIME_ALARM and ↵Lennart Poettering
CLOCK_BOOTTIME_ALARM, too
2014-03-23sd-rtnl: message - protect against SEGFAULT when reading messagesTom Gundersen
Make sure the returned data fits the datatype we requested. Otherwise return -EIO. Also fix a broken test that this exposed.
2014-03-23sd-rtnl: message - don't skip parts of message when parsingTom Gundersen
If a message type occurs repeatedly let the last one win. Also, don't skip type == MAX. Based on patch from: Susant Sahani <susant@redhat.com>
2014-03-22sd-rtnl: fix self-reference leaksDavid Herrmann
Like sd-bus, sd-rtnl can have self-references through queued messages. In particular, each queued message has the following self-ref loop: rtnl->wqueue[i]->rtnl == rtnl Same is true for "rqueue". When sd_rtnl_unref() gets called, we must therefore make sure we correctly consider each self-reference when deciding to destroy the object. For each queued message, there _might_ be one ref. However, rtnl-messages can be created _without_ a bus-reference, therefore we need to verify the actually required ref-count. Once we know exactly how many self-refs exist, and we verified none of the queued messages has external references, we can destruct the object. We must immediately drop our own reference, then flush all queues and destroy the bus object. Otherwise, each sd_rtnl_message_unref() call would recurse into the same destruction logic as they enter with the same rtnl-refcnt. Note: We really should verify _all_ queued messages have m->rtnl set to the bus they're queued on. If that's given, we can change: if (REFCNT_GET(rtnl->n_ref) <= refs) to if (REFCNT_GET(rtnl->n_ref) == refs) and thus avoid recalculating the required refs for each message we remove from the queue during destruction.
2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.
2014-03-16sd-rtnl: never treat broadcasts as repliesTom Gundersen
Otherwise the sequence number of a broadcast may match the sequence number of a pending unicast message and cause confusion.
2014-03-15sd-rtnl: make RTM_NEWLINK report EEXIST by defaultTom Gundersen
Use RTM_SETLINK to update an existing link.
2014-03-08sd-rtnl: increase default timeout to match sd-busTom Gundersen
2014-03-07sd-rtnl: introduce read ether and ip address functionsSusant Sahani
This patch introduces reading ethernet address and IPV4/IPv6 as well which is based on table based look up. [tomegun: rename read_ether() to read_ether_addr() to match the append function.]
2014-03-06sd-rtnl/networkd: use new rtnl_message_read() API and drop helperTom Gundersen
With the new sd_rtnl_message_read_string(), there is no longer a need for rtnl_message_get_ifname().
2014-03-06sd-rtnl:introduce table-based lookup and typesafe read() functionsSusant Sahani
This patch introduces new netlink attribute parsing logic which is table based lookup and sd_rtnl_message_read_* methods for reading attributes. By doing this user does not have to loop for the attribute values . Only providing the attribute type it gets the attribute values which is optimized and sd_rtnl_message_read_* methods are simplified.
2014-03-05sd-rtnl: do not blindly enter containers in message_read()Tom Gundersen
We need a separate container_enter() function, which will be part of a largerg API change. For now, just fix message_read().
2014-03-03sd-network: IPv4 link-local support [v2]Umut Tezduyar Lindskog
Implements IPv4LL with respect to RFC 3927 (http://tools.ietf.org/rfc/rfc3927.txt) and integrates it with networkd. Majority of the IPv4LL state machine is taken from avahi (http://avahi.org/) project's autoip. IPv4LL can be enabled by IPv4LL=yes under [Network] section of .network file. IPv4LL works independent of DHCP but if DHCP lease is aquired, then LL address will be dropped. [tomegun: removed a trailing newline and a compiler warning]
2014-02-25nspawn: add new switch --network-macvlan= to add a macvlan device to the ↵Lennart Poettering
container
2014-02-24Remove dead lines in various placesZbigniew Jędrzejewski-Szmek
As pointed-out by clang -Wunreachable-code. No behaviour changes.
2014-02-22test: always use assert_se in testsTom Gundersen
2014-02-20api: in constructor function calls, always put the returned object pointer ↵Lennart Poettering
first (or second) Previously the returned object of constructor functions where sometimes returned as last, sometimes as first and sometimes as second parameter. Let's clean this up a bit. Here are the new rules: 1. The object the new object is derived from is put first, if there is any 2. The object we are creating will be returned in the next arguments 3. This is followed by any additional arguments Rationale: For functions that operate on an object we always put that object first. Constructors should probably not be too different in this regard. Also, if the additional parameters might want to use varargs which suggests to put them last. Note that this new scheme only applies to constructor functions, not to all other functions. We do give a lot of freedom for those. Note that this commit only changes the order of the new functions we added, for old ones we accept the wrong order and leave it like that.
2014-02-19sd-rtnl: test - include missing.h to build on old kernelsTom Gundersen
2014-02-19missing.h: add some IFLA_* constantsTom Gundersen
These were added to the kernel between 3.5 and 3.9, let's not require such recent kernels (yet).
2014-02-18sd-rtnl-message: store reference to the bus in the messageTom Gundersen
This mimics the sd-bus api, as we may need it in the future.
2014-02-16sd-rtnl: do not require ifindex to be set for SETLINK messagesTom Gundersen
The kernel will then look up the ifindex itself based on the name. This should be used very carefully as it is racey. [This was a left-over hunk from my previous nspawn patch.]
2014-02-15sd-rtnl: always include linux/rtnetlink.hTom Gundersen
2014-02-15sd-rtnl: message_open_container - don't take a 'size' argumentTom Gundersen
We can always know the size based on the type, so let's do this inside the library.
2014-02-15sd-rtnl: link flags - don't allow change = 0Tom Gundersen
The kernel will happily treat 0x0 as 0xffffffff, but it is for backwards compatibility only, so let's not perpetuate this.
2014-02-13rtnl: support adding VETH_INFO_PEER containers into rtnl messagesLennart Poettering
2014-02-13rtnl: rename constructors from the form sd_rtnl_xxx_yyy_new() to ↵Lennart Poettering
sd_rtnl_xxx_new_yyy() So far we followed the rule to always indicate the "flavour" of constructors after the "_new_" or "_open_" in the function name, so let's keep things in sync here for rtnl and do the same.
2014-02-13rtnl: drop "sd_" prefix from cleanup macrosLennart Poettering
The "sd_" prefix is supposed to be used on exported symbols only, and not in the middle of names. Let's drop it from the cleanup macros hence, to make things simpler. The bus cleanup macros don't carry the "sd_" either, so this brings the APIs a bit nearer.
2014-02-10sd-rtnl: added support for a few more attributesSusant Sahani
2014-02-10sd-rtnl: test - improve test of MTU a bitTom Gundersen
We are more likely to catch errors if we don't use '0' as test value.
2014-02-10sd-rtnl: add test cases for linkSusant Sahani
2014-02-05Added attribute support for sd-rtnlSusant Sahani
Added sd_rtnl_message_append_u8 and few attribute support in sd_rtnl_message_append_u32 IFLA_GROUP, IFLA_TXQLEN, IFLA_NUM_TX_QUEUES, IFLA_NUM_RX_QUEUES
2014-01-30sd-rtnl: beef up rtnl-util a bitTom Gundersen
2014-01-25sd-rtnl: extend tests a bitTom Gundersen
2014-01-24sd-rtnl: add support for reading containersTom Gundersen
Also insist on messages being sealed before reading them. In other words we don't allow interleaving of reading and appending to messages.
2014-01-24sd-rtnl: add support for nested containersTom Gundersen
2014-01-22sd-rtnl: simplify sd_rtnl_message_addr_new()Tom Gundersen
Split out into sd_rtnl_message_addr_set_{prefixlen,flags,scope}().
2014-01-22sd-rtnl: add sd_rtnl_message_append_u16()Tom Gundersen
2014-01-22sd-rtnl: link - allow setting the change maskTom Gundersen
2014-01-21libsystemd: split up into subdirsTom Gundersen
We still only produce on .so, but let's keep the sources separate to make things a bit less messy.
