caif: fix a potential NULL dereference

2011-09-16T21:40:34+00:00

Commit bd30ce4bc0b7 (caif: Use RCU instead of spin-lock in caif_dev.c)
added a potential NULL dereference in case alloc_percpu() fails.

caif_device_alloc() can also use GFP_KERNEL instead of GFP_ATOMIC.

Remove redundant linux/version.h includes from net/

2011-06-21T23:03:17+00:00

It was suggested by "make versioncheck" that the follwing includes of
linux/version.h are redundant:

  /home/jj/src/linux-2.6/net/caif/caif_dev.c: 14 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/caif/chnl_net.c: 10 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/ipv4/gre.c: 19 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/netfilter/ipset/ip_set_core.c: 20 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/netfilter/xt_set.c: 16 linux/version.h not needed.

and it seems that it is right.

Beyond manually inspecting the source files I also did a few build
tests with various configs to confirm that including the header in
those files is indeed not needed.

Here's a patch to remove the pointless includes.

caif: Bugfix - XOFF removed channel from caif-mux

2011-06-17T03:59:09+00:00

XOFF was mixed up with DOWN indication, causing causing CAIF channel to be
removed from mux and all incoming traffic to be lost after receiving flow-off.
Fix this by replacing FLOW_OFF with DOWN notification.

caif: Plug memory leak for checksum error

2011-05-23T00:11:49+00:00

In case of checksum error, the framing layer returns -EILSEQ, but
does not free the packet. Plug this hole by freeing the packet if
-EILSEQ is returned.

caif: Fixes freeze on Link layer removal.

2011-05-23T00:11:47+00:00

CAIF Socket layer - caif_socket.c:
- Plug mem-leak at reconnect.
- Always call disconnect to cleanup CAIF stack.
- Disconnect will always report success.

CAIF configuration layer - cfcnfg.c
- Disconnect must dismantle the caif stack correctly
- Protect against faulty removals (check on id zero)

CAIF mux layer - cfmuxl.c
- When inserting new service layer in the MUX remove
  any old entries with the same ID.
- When removing CAIF Link layer, remove the associated
  service layers before notifying service layers.
