* net: annotate lockless accesses to sk->sk_max_ack_backlogEric Dumazet2019-11-069-10/+10
| | | | | | | | | | | sk->sk_max_ack_backlog can be read without any lock being held at least in TCP/DCCP cases. We need to use READ_ONCE()/WRITE_ONCE() to avoid load/store tearing and/or potential KCSAN warnings. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

| | | | | | | | | | | | | | There are common instances of the following construct : if (n->confirmed != now) n->confirmed = now; A C compiler could legally remove the conditional.

* gianfar: Maximize Rx buffer sizeClaudiu Manoil2019-11-061-4/+4
| | | | | | | | | | | | | | | | | | Until now the size of a Rx buffer was artificially limited to 1536B (which happens to be the default, after reset, hardware value for a Rx buffer). This approach however leaves unused memory space for Rx packets, since the driver uses a paged allocation scheme that reserves half a page for each Rx skb. There's also the inconvenience that frames around 1536 bytes can get scattered if the limit is slightly exceeded. This limit can be exceeded even for standard MTU of 1500B traffic, for common cases like stacked VLANs, or DSA tags. To address these issues, let's just compute the buffer size starting from the upper limit of 2KB (half a page) and subtract the skb overhead and alignment restrictions.

* net: forcedeth: add xmit_more supportZhu Yanjun2019-11-061-10/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds support for xmit_more based on the igb commit 6f19e12f6230 ("igb: flush when in xmit_more mode and under descriptor pressure") and commit 6b16f9ee89b8 ("net: move skb->xmit_more hint to softnet data") that were made to igb to support this feature. The function netif_xmit_stopped is called to check whether transmit queue on device is currently unable to send to determine whether we must write the tail because we can add no further buffers. When normal packets and/or xmit_more packets fill up tx_desc, it is necessary to trigger NIC tx reg. Following the advice from David Miller and Jakub Kicinski, after the xmit_more feature is added, the following scenario will occur. | xmit_more packets | DMA_MAPPING | DMA_MAPPING error check | xmit_more packets already in HW xmit queue | In the above scenario, if DMA_MAPPING error occurrs, the xmit_more packets already in HW xmit queue will also be dropped. This is different from the behavior before xmit_more feature. So it is necessary to trigger NIC HW tx reg in the above scenario. To the non-xmit_more packets, the above scenario will not occur.

| * netdevsim: drop code duplicated by a mergeJakub Kicinski2019-11-061-39/+8
|/ | | | | | | | | | | | | | | | | | | | Looks like the port adding loop makes a re-appearance on net-next after net was merged back into it (even though it doesn't feature in the merge diff). The ports are already added in nsim_dev_create() so when we try to add them again get EEXIST, and see: netdevsim: probe of netdevsim0 failed with error -17 in the logs. When we remove the loop again the nsim_dev_probe() and nsim_dev_remove() become a wrapper of nsim_dev_create() and nsim_dev_destroy(). Remove this layer of indirection.
