| H A D | firewire.c | diff 249291 Mon Apr 08 21:26:09 MDT 2013 will FireWire: Don't allow a tlabel to reference an xfer after free. sys/dev/firewire/firewire.c: - fw_xfer_unload(): Since we are about to free this xfer, call fw_tl_free() to remove the xfer from its tlabel's list, if it has a tlabel. - In every occasion when a xfer is removed from a tlabel's list, reset xfer->tl to -1 while holding fc->tlabel_lock, so that the xfer isn't mis-identified as belonging to a tlabel. This doesn't fix all the use-after-free problems for M_FWMEM, but is an incremental towards that goal. Reviewed by: kan, sbruno Sponsored by: Spectra Logic |
