• 20dd3850b   can: Speed up CAN frame receiption by using ml_priv ... Browse Code »

  this patch removes the hlist that contains the CAN receiver filter lists.
  It uses the 'midlayer private' pointer ml_priv and links the filters directly
  to the CAN netdevice, which allows to omit the walk through the complete CAN
  devices hlist for each received CAN frame.

  This patch is tested and does not remove any locking.

• 99b762338   proc 2/2: remove struct proc_dir_entry::owner ... Browse Code »

  Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
  as correctly noted at bug #12454. Someone can lookup entry with NULL
  ->owner, thus not pinning enything, and release it later resulting
  in module refcount underflow.

  We can keep ->owner and supply it at registration time like ->proc_fops
  and ->data.

  But this leaves ->owner as easy-manipulative field (just one C assignment)
  and somebody will forget to unpin previous/pin current module when
  switching ->owner. ->proc_fops is declared as "const" which should give
  some thoughts.

  ->read_proc/->write_proc were just fixed to not require ->owner for
  protection.

  rmmod'ed directories will be empty and return "." and ".." -- no harm.
  And directories with tricky enough readdir and lookup shouldn't be modular.
  We definitely don't want such modular code.

  Removing ->owner will also make PDE smaller.

  So, let's nuke it.

  Kudos to Jeff Layton for reminding about this, let's say, oversight.

• 0d66548a1   [CAN]: Add PF_CAN core module ... Browse Code »

  This patch adds the CAN core functionality but no protocols or drivers.
  No protocol implementations are included here. They come as separate
  patches. Protocol numbers are already in include/linux/can.h.
