Moreover stop listing all i.MX platforms featuring a FEC, and use the platform's config symbol that selects registration of a fec device instead. This might make it easier to add new platforms.

由 David S. Miller 提交于
In commit aa942104 ("net: init ingress queue") we moved the allocation and lock initialization of the queues into alloc_netdev_mq() since register_netdevice() is way too late. The problem is that dev->type is not setup until the setup() callback is invoked by alloc_netdev_mq(), and the dev->type is what determines the lockdep class to use for the locks in the queues. Fix this by doing the queue allocation after the setup() callback runs. This is safe because the setup() callback is not allowed to make any state changes that need to be undone on error (memory allocations, etc.). It may, however, make state changes that are undone by free_netdev() (such as netif_napi_add(), which is done by the ipoib driver's setup routine). The previous code also leaked a reference to the &init_net namespace object on RX/TX queue allocation failures. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 David S. Miller 提交于
rtnl_link_ops->setup(), and the "setup" callback passed to alloc_netdev*(), cannot make state changes which need to be undone on failure. There is no cleanup mechanism available at this point. So we have to add the caif private instance to the global list once we are sure that register_netdev() has succedded in ->newlink(). Otherwise, if register_netdev() fails, the caller will invoke free_netdev() and we will have a reference to freed up memory on the chnl_net_list. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Currently the driver increments the tx_timeout counter (an error counter) when simply resetting the part with outstanding transmit work pending. This is an unnecessary count of an error, when all we should be doing is just resetting the part and discarding the transmits. With this change the only increment of tx_timeout is when the stack calls the watchdog reset function due to a true Tx timeout.

Originally x25_parse_facilities returned -1 for an error 0 meaning 0 length facilities >0 the length of the facilities parsed. 5ef41308 ("x25: Prevent crashing when parsing bad X.25 facilities") introduced more error checking in x25_parse_facilities however used 0 to indicate bad parsing a6331d6f ("memory corruption in X.25 facilities parsing") followed this further for DTE facilities, again using 0 for bad parsing. The meaning of 0 got confused in the callers. If the facilities are messed up we can't determine where the data starts. So patch makes all parsing errors return -1 and ensures callers close and don't use the skb further.

Using skb_header_cloned to check if it's safe to write to the skb is not enough - mac80211 also touches the tailroom of the skb. Initially this check was only used to increase a counter, however this commit changed the code to also skip skb data reallocation if no extra head/tailroom was needed: commit 4cd06a34 mac80211: skip unnecessary pskb_expand_head calls It added a regression at least with iwl3945, which is fixed by this patch.
