Changes to the FireWire kernel drivers in Linux 3.14 and 3.15

[Stefan R. <st...@s5...>]

Hi all,

somewhat late, here are IEEE 1394 subsystem release notes for the last two
kernel releases:

*Linux 3.14, released on March 30*

firewire-net
  - Fix a use-after-free bug which could occur after transmission
    failures. 

firewire-ohci
  - The new module parameter "remote_dma" (default = N, enable unfiltered
    remote DMA = Y) replaces the former build-time option
    CONFIG_FIREWIRE_OHCI_REMOTE_DMA.  (This kernel configuration option was
    located in the "Kernel hacking" menu, item "Remote debugging over
    FireWire with firewire-ohci".)  It is therefore now possible to switch
    on RDMA at runtime on all kernels with firewire-ohci loaded or
    built-in, for example for remote debugging, without the need for a
    custom build option.
  - Fix initialization failure with Agere FW323 and some other Agere/LSI
    controllers. These failures were a regression since Linux v3.10
    inclusive. Also fixed in v3.13.7, v3.12.15, v3.11.10.7, v3.10.41. 

*Linux 3.15, released on June 8*

firewire-core, firewire-ohci
  - A feature was added in v3.14 to enable remote DMA from and to memory
    outside the 32 bit range of physical addresses, which is possible at
    least with LSI FW643 controllers.  This feature clashed with at least
    one vendor-specific device control protocol and was therefore reverted
    in v3.15 and v3.14.7.
