Request for -stable inclusion (xt_TCPMSS)

Hi David, Please queue 2638fd0f92d4 ("netfilter: xt_TCPMSS: add more sanity tests on tcph->doff") for -stable. It fixes hard to debug crashes in production, that can be triggered by remote peers. Regards, Guillaume

[PATCH 02/11] dma-mapping: replace dmam_alloc_noncoherent with dmam_alloc_attrs

remove dma_alloc_noncoherent

For many years we've had the dma_alloc_attrs API that is more flexible than dma_alloc_noncoherent. This series moves the remaining users over to the attrs API.

[PATCH 1/5] networking: convert many more places to skb_put_zero()

From: Johannes Berg There were many places that my previous spatch didn't find, as pointed out by yuan linyu in various patches. The following spatch found many more and also removes the now unnecessary casts: @@ identifier p, p2; expression len; expression skb; type t, t2;

[PATCH 0/5] skb data accessors cleanup

Hi, Over night, Fengguang's bot told me that it compiled all of its many various configurations successfully, and I had done allyesconfig on x86_64 myself yesterday to iron out the things I missed. So now I think I'm happy with it. My tree was based on your commit 3715c47bcda8bb56f7e2be2727

[PATCH 5/5] networking: make skb_push & __skb_push return void pointers

From: Johannes Berg It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer w

[PATCH net] net: 8021q: Fix one possible panic caused by BUG_ON in free_netdev

From: Gao Feng The register_vlan_device would invoke free_netdev directly, when register_vlan_dev failed. It would trigger the BUG_ON in free_netdev if the dev was already registered. In this case, the netdev would be freed in netdev_run_todo later. So add one condition check now. Only when dev
