media: dvb_net: fix dvb_net_tx()'s return type

2018-05-05T14:21:40Z

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, but the implementation in this driver returns an 'int'. Fix this by returning 'netdev_tx_t' in this driver too. Signed-off-by: Luc Van Oostenryck Signed-off-by: Mauro Carvalho Chehab

media: dvb: update buffer mmaped flags and frame counter

media: move dvb kAPI headers to include/media

media: dvb_net: let dynamic debug enable some DVB net handling

pr_debug() and netdev_dbg() can be enabled/disabled dynamically via sysfs. So, stop hidding them under ULE_DEBUG config macro. Signed-off-by: Mauro Carvalho Chehab

media: dvb-core: allow users to enable DVB net ULE debug

2017-12-19T11:29:27Z

This debug option is there for a long time, but it is only enabled by editing the source code. Due to that, a breakage inside its code was only noticed years after a change at the ULE handling logic. Make it a Kconfig parameter, as it makes easier for advanced users to enable, and allow test if the compilation won't be broken in the future. Signed-off-by: Mauro Carvalho Chehab

media: dvb_net: ensure that dvb_net_ule_handle is fully initialized

2017-12-19T11:28:42Z

commit efb9ab67255f ("[media] dvb_net: prepare to split a very complex function") changed the ULE handling logic, simplifying it. However, it forgot to keep the initialization for .priv and to zero .ule_hist fields. The lack of .priv cause crashes if dvb_net_ule() is called, as the function assuems that .priv field to be initialized. With regards to .ule_hist, the current logic is broken and don't even compile if ULE_DEBUG. Fix it by making the debug vars static again, and be sure to pass iov parameter to dvb_net_ule_check_crc().

networking: make skb_put & friends return void pointers

2017-06-16T15:48:39Z

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 Signed-off-by: David S. Miller

networking: introduce and use skb_put_data()

2017-06-16T15:48:37Z

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; ... ( -p = skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); | -p = (t *)skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); ) ( p2 = (t2)p; -memcpy(p2, data, sizeof(*p)); | -memcpy(p, data, sizeof(*p)); ) @@ expression skb, len, data; @@ -memcpy(skb_put(skb, len), data, len); +skb_put_data(skb, data, len); (again, manually post-processed to retain some comments) Reviewed-by: Stephen Hemminger Signed-off-by: Johannes Berg Signed-off-by: David S.
