The following commit has been merged in the master branch: commit 59ae1d127ac0ae404baf414c434ba2651b793f46 Author: Johannes Berg <johannes.berg(a)intel.com> Date: Fri Jun 16 14:29:20 2017 +0200 networking: introduce and use skb_put_data() A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this. An spatch similar to the one for skb_put_zero() converts many of the places using it: @@ identifier p, p2; expression len, skb, data; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_data(skb, data, len); | -p = (t)skb_put(skb, len); +p = skb_put_data(skb, data, len); ) ( p2 = (t2)p; -memcpy(p2, data, len); | -memcpy(p, data, len); ) @@ type t, t2; identifier p, p2; expression skb, data; @@ t *p; ...

The following commit has been merged in the master branch: commit 4df864c1d9afb46e2461a9f808d9f11a42d31bad Author: Johannes Berg <johannes.berg(a)intel.com> Date: Fri Jun 16 14:29:21 2017 +0200 networking: make skb_put & friends return void pointers 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 (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: Johannes Berg <johannes.berg(a)intel.com> Signed-off-by: David S.

The following commit has been merged in the master branch: commit b080db585384b9f037e015c0c28d1ad33be41dfc Author: Johannes Berg <johannes.berg(a)intel.com> Date: Fri Jun 16 14:29:19 2017 +0200 networking: convert many more places to skb_put_zero() There were many places that my previous spatch didn't find, as pointed out by yuan linyu in various patches.
