firewire: fix "kobject_add failed for fw* with -EEXIST" There is a race between shutdown and creation of devices: fw-core may attempt to add a device with the same name of an already existing device. http://bugzilla.kernel.org/show_bug.cgi?id=9828 Impact of the bug: Happens rarely (when shutdown of a device coincides with creation of another), forces the user to unplug and replug the new device to get it working. The fix is obvious: Free the minor number *after* instead of *before* device_unregister(). This requires to take an additional reference of the fw_device as long as the IDR tree points to it. And while we are at it, we fix an additional race condition: fw_device_op_open() took its reference of the fw_device a little bit too late, hence was in danger to access an already invalid fw_device.

firewire: prevent userspace from accessing shut down devices If userspace ignores the POLLERR bit from poll(), and only attempts to read() the device when POLLIN is set, it can still make ioctl() calls on a device that has been removed from the system. The node_id and generation returned by GET_INFO will be outdated, but INITIATE_BUS_RESET would still cause a bus reset, and GET_CYCLE_TIMER will return data. And if you guess the correct generation to use, you can send requests to a different device on the bus, and get responses back. This patch prevents open, ioctl, compat_ioctl, and mmap against shutdown devices. Signed-off-by: Jay Fenlason <fenlason@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

firewire: fill_bus_reset_event needs lock protection Callers of fill_bus_reset_event() have to take card->lock. Otherwise access to node data may oops if node removal is in progress. A lockless alternative would be - event->local_node_id = card->local_node->node_id; + tmp = fw_node_get(card->local_node); + event->local_node_id = tmp->node_id; + fw_node_put(tmp); and ditto with the other node pointers which fill_bus_reset_event() accesses. But I went the locked route because one of the two callers already holds the lock. As a bonus, we don't need the memory barrier anymore because device->generation and device->node_id are written in a card->lock protected section.

firewire: reread config ROM when device reset the bus When a device changes its configuration ROM, it announces this with a bus reset. firewire-core has to check which node initiated a bus reset and whether any unit directories went away or were added on this node. Tested with an IOI FWB-IDE01AB which has its link-on bit set if bus power is available but does not respond to ROM read requests if self power is off. This implements - recognition of the units if self power is switched on after fw-core gave up the initial attempt to read the config ROM, - shutdown of the units when self power is switched off. Also tested with a second PC running Linux/ieee1394. When the eth1394 driver is inserted and removed on that node, fw-core now notices the addition and removal of the IPv4 unit on the ieee1394 node.

firewire: support S100B...S400B and link slower than PHY Use a speed probe to determine the speed over 1394b buses and of nodes which report a link speed less than their PHY speed. Log the effective maximum speed of newly created nodes in dmesg. Also, read the config ROM (except bus info block) at the maximum speed rather than S100. This isn't a real optimization though because we still only use quadlet read requests for the entire ROM. The patch also adds support for S1600 and S3200, although such hardware does not exist yet.

This patch replaces the bitfields with a __u32 'control' word and provides access macros to set the bits.
