2019-06-03net: ena: add support for changing max_header_size in LLQ modeSameeh Jubran1-6/+4
Up until now the driver always used a single setting for the sizes of the different parts of the llq entry - 128 for entry size, 2 for descriptors before header and 96 for maximum header size. The current code makes sure that the parts of the llq entry are compatible with each other and with the initial llq entry size given by the device.

2019-06-03net: ena: replace free_tx/rx_ids union with single free_ids field in ena_ringSameeh Jubran2-31/+28
struct ena_ring holds a union of free_rx_ids and free_tx_ids. Both of the above fields mean the exact same thing and are used exactly the same way. Furthermore, these fields are always used with a prefix of the type of ring. So for tx it will be tx_ring->free_tx_ids, and for rx it will be rx_ring->free_rx_ids, which shows how redundant the "_tx" and "_rx" parts are. Furthermore still, this may lead to confusing code like where tx_ring->free_rx_ids which works correctly but looks like a mess. This commit removes the aforementioned redundancy by replacing the free_rx/tx_ids union with a single free_ids field. It also changes a single goto label name from err_free_tx_ids: to err_tx_free_ids: for consistency with the above new notation.

2019-06-03net: ena: add handling of llq max tx burst sizeSameeh Jubran6-17/+85
There is a maximum TX burst size that the ENA device can handle. It is exposed by the device to the driver and the driver needs to comply with it to avoid bugs. In this commit we: 1. Add ena_com_is_doorbell_needed(), which calculates the number of llq entries that will be used to hold a packet, and will return true if they exceed the number of allowed entries in a burst. If the function returns true, a doorbell needs to be invoked to send this packet in the next burst. 2. Follow the available entries in the current burst: - Every doorbell a new burst begins - With each write of an llq entry, the available entries in the current burst are decreased by 1.

2019-06-02devinet: use in_dev_for_each_ifa_rcu in more placesFlorian Westphal1-8/+19
This also replaces spots that used for_primary_ifa(). for_primary_ifa() aborts the loop on the first secondary address seen. Replace it with either the rcu or rtnl variant of in_dev_for_each_ifa(), but two places will now also consider secondary addresses too: inet_addr_onlink() and inet_ifa_byprefix(). I do not understand why they should ignore secondary addresses. Why would a secondary address not be considered 'on link'? When matching a prefix, why ignore a matching secondary address? Other places get converted as well, but gain "->flags & SECONDARY" check. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-06-02net: inetdevice: provide replacement iterators for in_ifaddr walkFlorian Westphal2-16/+25

This adds two iterators as replacement, a later patch in the series will update them with the needed rcu/rtnl_dereference calls. Its not done in this patch yet to avoid sparse warnings -- the fields lack the proper __rcu annotation. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.

2019-06-02afs: do not send list of client addressesFlorian Westphal4-87/+1
David Howells says: I'm told that there's not really any point populating the list. Current OpenAFS ignores it, as does AuriStor - and IBM AFS 3.6 will do the right thing. The list is actually useless as it's the client's view of the world, not the servers, so if there's any NAT in the way its contents are invalid. Further, it doesn't support IPv6 addresses. On that basis, feel free to make it an empty list and remove all the interface enumeration. V1 of this patch reworked the function to use a new helper for the ifa_list iteration to avoid sparse warnings once the proper __rcu annotations get added in struct in_device later. But, in light of the above, just remove afs_get_ipv4_interfaces. Compile tested only.
