2012-09-04staging: gdm72xx: use kzalloc to allocate usb_tx structureDevendra Naga2-6/+2
the code under alloc_tx_struct does the allocation of usb_tx structure using kmalloc, and memsets the allocated pointer, instead we can directly use kzalloc so that the allocated memory is set with zeros Signed-off-by: Devendra Naga <devendra.aaru@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Pull second vfs pile from Al Viro: "The stuff in there: fsfreeze deadlock fixes by Jan (essentially, the deadlock reproduced by xfstests 068), symlink and hardlink restriction patches, plus assorted cleanups and fixes. Note that another fsfreeze deadlock (emergency thaw one) is *not* dealt with - the series by Fernando conflicts a lot with Jan's, breaks userland ABI (FIFREEZE semantics gets changed) and trades the deadlock for massive vfsmount leak; this is going to be handled next cycle.

All of these have gotten acks from the various subsystem maintainers to be included in this tree.

2012-06-29netlink: add netlink_kernel_cfg parameter to netlink_kernel_createPablo Neira Ayuso1-2/+4
This patch adds the following structure: struct netlink_kernel_cfg { unsigned int groups; void (*input)(struct sk_buff *skb); struct mutex *cb_mutex; }; That can be passed to netlink_kernel_create to set optional configurations for netlink kernel sockets. I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

2012-06-26staging: gdm72xx: fix an skb memory leakJavier Martinez Canillas1-3/+7
The NLMSG_PUT() macro contains a hidden goto that jumps to the nlmsg_failure label. Since the sk_buff was allocated before the macro, jumping to the nlmsg_failure label leaks the memory allocated for it. Calling kfree() before returning would fix it, but is better to avoid using this error prone macro and use nlmsg_put() instead. Also, use nlmsg_data() instead of NLMSG_DATA() to check type.
