2009-06-16firewire: core: fix iso context shutdown on card removalStefan Richter
If isochronous contexts existed when firewire-ohci was unloaded, the core iso shutdown functions crashed with NULL dereferences, and buffers etc. weren't released. How the fix works: We first copy the card driver's iso shutdown hooks into the dummy driver, then fw_destroy_nodes notifies upper layers of devices going away, these should shut down (including their iso contexts), wait_for_completion(&card->done) will be triggered after upper layers gave up all fw_device references, after which the card driver's shutdown proceeds.

2009-06-14firewire: net: allow for unordered unit discoveryStefan Richter
Decouple the creation and destruction of the net_device from the order of discovery and removal of nodes with RFC 2734 unit directories since there is no reliable order. The net_device is now created when the first RFC 2734 unit on a card is discovered, and destroyed when the last RFC 2734 unit on a card went away. This includes all remote units as well as the local unit, which is therefore tracked as a peer now too. Also, locking around the list of peers is slightly extended to guard against peer removal. As a side effect, fwnet_peer.pdg_lock has become superfluous and is deleted. Peer data (max_rec, speed, node ID, generation) are updated more carefully.

2009-06-14firewire: net: style changesStefan Richter
Change names of types, variables, functions. Omit debug code. Use get_unaligned*, put_unaligned*. Annotate big endian data. Handle errors in __init. Change whitespace. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2009-06-14firewire: add IPv4 supportJay Fenlason
Implement IPv4 over IEEE 1394 as per RFC 2734 for the newer firewire stack. This feature has only been present in the older ieee1394 stack via the eth1394 driver. Still to do: - fix ipv4_priv and ipv4_node lifetime logic - fix determination of speeds and max payloads - fix bus reset handling - fix unaligned memory accesses - fix coding style - further testing/ improvement of fragment reassembly - perhaps multicast support Signed-off-by: Jay Fenlason <fenlason@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (rebased, copyright note, changelog)
2009-06-06firewire: core: prepare for non-core children of card devicesStefan Richter
The IP-over-1394 driver will add child devices beneath card devices which are not of type fw_device. Hence firewire-core's callbacks in device_for_each_child() and device_find_child() need to check for the device type now. Initial version written by Jay Fenlason.

2009-06-05firewire: rename source filesStefan Richter
The source files of firewire-core, firewire-ohci, firewire-sbp2, i.e. "drivers/firewire/fw-*.c" are renamed to "drivers/firewire/core-*.c", "drivers/firewire/ohci.c", "drivers/firewire/sbp2.c". The old fw- prefix was redundant to the directory name. The new core- prefix distinguishes the files according to which driver they belong to. This change comes a little late, but still before further firewire drivers are added as anticipated RSN. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
