net: convert sock.sk_wmem_alloc from atomic_t to refcount_t

2017-07-01T14:39:08Z

refcount_t type and corresponding API should be used instead of atomic_t when the variable is used as a reference counter. This allows to avoid accidental refcounter overflows that might lead to use-after-free situations.

caif: Add sockaddr length check before accessing sa_family in connect handler

2017-06-13T20:16:11Z

Verify that the caller-provided sockaddr structure is large enough to contain the sa_family field, before accessing it in the connect() handler of the AF_CAIF socket. Since the syscall doesn't enforce a minimum size of the corresponding memory region, very short sockaddrs (zero or one byte long) result in operating on uninitialized memory while referencing sa_family.

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:29Z

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

net: caif: remove ineffective check

2016-12-05T19:48:48Z

The check of the return value of sock_register() is ineffective. "if(!err)" seems to be a typo. It is better to propagate the error code to the callers of caif_sktinit_module(). This patch removes the check statment and directly returns the result of sock_register(). Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=188751 Signed-off-by: Pan Bian Signed-off-by: David S.

net: rename SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATA

2015-12-01T20:45:05Z

This patch is a cleanup to make following patch easier to review. Goal is to move SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATA from (struct socket)->flags to a (struct socket_wq)->flags to benefit from RCU protection in sock_wake_async() To ease backports, we rename both constants. Two new helpers, sk_set_bit(int nr, struct sock *sk) and sk_clear_bit(int net, struct sock *sk) are added so that following patch can change their implementation.

caif: fix leaks and race in caif_queue_rcv_skb()

2015-07-21T07:02:44Z

1) If sk_filter() is applied, skb was leaked (not freed) 2) Testing SOCK_DEAD twice is racy : packet could be freed while already queued. 3) Remove obsolete comment about caching skb->len Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
