net: Remove the obsolte u64_stats_fetch_*_irq() users (drivers).

2022-10-29T03:13:54Z

Now that the 32bit UP oddity is gone and 32bit uses always a sequence count, there is no need for the fetch_irq() variants anymore. Convert to the regular interface.

net: ethernet: rmnet: Replace zero-length array with DECLARE_FLEX_ARRAY() helper

2022-09-28T08:40:31Z

Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length arrays declarations in anonymous union with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members in unions.

net: add per-cpu storage and net->core_stats

2022-03-12T07:17:24Z

Before adding yet another possibly contended atomic_long_t, it is time to add per-cpu storage for existing ones: dev->tx_dropped, dev->rx_dropped, and dev->rx_nohandler Because many devices do not have to increment such counters, allocate the per-cpu storage on demand, so that dev_get_stats() does not have to spend considerable time folding zero counters. Note that some drivers have abused these counters which were supposed to be only used by core networking stack. v4: should use per_cpu_ptr() in dev_get_stats() (Jakub) v3: added a READ_ONCE() in netdev_core_stats_alloc() (Paolo) v2: add a missing include (reported by kernel test robot ) Change in netdev_core_stats_alloc() (Jakub) Signed-off-by: Eric Dumazet Cc: jeffreyji Reviewed-by: Brian Vazquez Reviewed-by: Jakub Kicinski Acked-by: Paolo Abeni Link: https://lore.kernel.org/r/20220311051420.2608812-1-eric.dumazet@gmail.com Signed-off-by: Jakub Kicinski

net: qualcomm: rmnet: Use skb_put_zero() to simplify code

2022-02-21T11:58:48Z

Use skb_put_zero() instead of hand-writing it. This saves a few lines of code and is more readable. Signed-off-by: Christophe JAILLET Signed-off-by: David S. Miller

ethernet: make use of eth_hw_addr_random() where appropriate

2021-10-14T16:22:15Z

Number of drivers use eth_random_addr(netdev->dev_addr) thus writing to netdev->dev_addr directly, and not setting the address type. Switch them to eth_hw_addr_random(). @@ expression netdev; @@ - eth_random_addr(netdev->dev_addr); + eth_hw_addr_random(netdev); Reviewed-by: Linus Walleij Signed-off-by: Jakub Kicinski

net: qualcomm: rmnet: fix two pointer math bugs

2021-06-21T19:19:19Z

We recently changed these two pointers from void pointers to struct pointers and it breaks the pointer math so now the "txphdr" points beyond the end of the buffer.

net: qualcomm: rmnet: Allow partial updates of IFLA_FLAGS

2021-06-16T19:16:22Z

The idiomatic way to handle the changelink flags/mask pair seems to be allow partial updates of the driver's link flags. In contrast the rmnet driver masks the incoming flags and then use that as the new flags. Change the rmnet driver to follow the common scheme, before the introduction of IFLA_RMNET_FLAGS handling in iproute2 et al.

net: qualcomm: rmnet: always expose a few functions

2021-06-14T19:43:45Z

A recent change tidied up some conditional code, avoiding the use of some #ifdefs. Unfortunately, if CONFIG_IPV6 was not enabled, it meant that two functions were referenced but never defined. The easiest fix is to just define stubs for these functions if CONFIG_IPV6 is not defined. This will soon be simplified further by some other development in the works...
