dlm: keep listening connection alive with sctp mode

2014-06-12T15:26:14+00:00

The connection struct with nodeid 0 is the listening socket,
not a connection to another node.  The sctp resend function
was not checking that the nodeid was valid (non-zero), so it
would mistakenly get and resend on the listening connection
when nodeid was zero.

net: Fix use after free by removing length arg from sk_data_ready callbacks.

2014-04-11T20:15:36+00:00

Several spots in the kernel perform a sequence like:

	skb_queue_tail(&sk->s_receive_queue, skb);
	sk->sk_data_ready(sk, skb->len);

But at the moment we place the SKB onto the socket receive queue it
can be consumed and freed up.  So this skb->len access is potentially
to freed up memory.

Furthermore, the skb->len can be modified by the consumer so it is
possible that the value isn't accurate.

And finally, no actual implementation of this callback actually uses
the length argument.  And since nobody actually cared about it's
value, lots of call sites pass arbitrary values in such as '0' and
even '1'.

So just remove the length argument from the callback, that way there
is no confusion whatsoever and all of these use-after-free cases get
fixed as a side effect.

Based upon a patch by Eric Dumazet and his suggestion to audit this
issue tree-wide.

dlm: use INFO for recovery messages

2014-02-14T17:54:44+00:00

The log messages relating to the progress of recovery
are minimal and very often useful.  Change these to
the KERN_INFO level so they are always available.

fs: Include appropriate header file in dlm/ast.c

2014-02-12T21:44:19+00:00

Include appropriate header file fs/dlm/ast.h in fs/dlm/ast.c because it
contains function prototypes of some functions defined in fs/dlm/ast.c.

This also eliminates the following warning in fs/dlm/ast:
fs/dlm/ast.c:52:5: warning: no previous prototype for ‘dlm_add_lkb_callback’ [-Wmissing-prototypes]
fs/dlm/ast.c:113:5: warning: no previous prototype for ‘dlm_rem_lkb_callback’ [-Wmissing-prototypes]
