* ipmr, ip6mr: add RTNH_F_UNRESOLVED flag to unresolved cache entriesNikolay Aleksandrov2017-01-031-0/+1
| | | | | | | | | | | | | While working with ipmr, we noticed that it is impossible to determine if an entry is actually unresolved or its IIF interface has disappeared (e.g. virtual interface got deleted). These entries look almost identical to user-space when dumping or receiving notifications. So in order to recognize them add a new RTNH_F_UNRESOLVED flag which is set when sending an unresolved cache entry to user-space.

It needs some more work to fully support old/new tools matrix. - Addressed Dave's comment about bool usage in patch "RDS: IB: track and log active side..." v1->v2: Re-aligned indentation in patch 'RDS: mark few internal functions..." Series consist of: - RDMA transport fixes for map failure, listen sequence, handler panic and composite message notification. - Couple of sparse fixes. - Message logging improvements for bind failure, use once mr semantics and connection remote address, active end point. - Performance improvement for RDMA transport by reducing the post send pressure on the queue and spreading the CQ vectors. - Useful statistics for socket send/recv usage and receive cache usage. - Additional RDS CMSG used by application to track the RDS message stages for certain type of traffic to find out latency spots. Can be enabled/disabled per socket. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| * RDS: add receive message trace used by applicationSantosh Shilimkar2017-01-021-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | Socket option to tap receive path latency in various stages in nano seconds. It can be enabled on selective sockets using using SO_RDS_MSG_RXPATH_LATENCY socket option. RDS will return the data to application with RDS_CMSG_RXPATH_LATENCY in defined format. Scope is left to add more trace points for future without need of change in the interface.

| | | | | | | | | | | | | | | | | For core revision 3.x Address-Aligned Beats is available in two registers.

The DT property snps,axi_all was created for AXI_AAL in the AXI bus mode register, which is a read only bit that reflects the value of AAL in the DMA bus register. Since the value of snps,axi_all is never used in the driver, and since the property was created for a bit that is read only, it should be safe to remove the property.

* net: dev_weight: TX/RX orthogonalityMatthias Tafelmeier2016-12-291-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Oftenly, introducing side effects on packet processing on the other half of the stack by adjusting one of TX/RX via sysctl is not desirable. There are cases of demand for asymmetric, orthogonal configurability. This holds true especially for nodes where RPS for RFS usage on top is configured and therefore use the 'old dev_weight'. This is quite a common base configuration setup nowadays, even with NICs of superior processing support (e.g. aRFS). A good example use case are nodes acting as noSQL data bases with a large number of tiny requests and rather fewer but large packets as responses. It's affordable to have large budget and rx dev_weights for the requests. But as a side effect having this large a number on TX processed in one run can overwhelm drivers. This patch therefore introduces an independent configurability via sysctl to userland. Signed-off-by: Matthias Tafelmeier <matthias.tafelmeier@gmx.net> Signed-off-by: David S.

The most important is to not assume the packet is RX just because the destination address matches that of the device. Such an assumption causes problems when an interface is put into loopback mode. 2) If we retry when creating a new tc entry (because we dropped the RTNL mutex in order to load a module, for example) we end up with -EAGAIN and then loop trying to replay the request. But we didn't reset some state when looping back to the top like this, and if another thread meanwhile inserted the same tc entry we were trying to, we re-link it creating an enless loop in the tc chain. Fix from Daniel Borkmann. 3) There are two different WRITE bits in the MDIO address register for the stmmac chip, depending upon the chip variant. Due to a bug we could set them both, fix from Hock Leong Kweh. 4) Fix mlx4 bug in XDP_TX handling, from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net: stmmac: fix incorrect bit set in gmac4 mdio addr register r8169: add support for RTL8168 series add-on card. net: xdp: remove unused bfp_warn_invalid_xdp_buffer() openvswitch: upcall: Fix vlan handling. ipv4: Namespaceify tcp_tw_reuse knob net: korina: Fix NAPI versus resources freeing net, sched: fix soft lockup in tc_classify net/mlx4_en: Fix user prio field in XDP forward tipc: don't send FIN message from connectionless socket ipvlan: fix multicast processing ipvlan: fix various issues in ipvlan_process_multicast()

This can be tested rather than testing waitqueue_active which requires another cacheline load. This bit is always set when the page has tasks on page_waitqueue(page), and is set and cleared under the waitqueue lock. It may be set when there are no tasks on the waitqueue, which will cause a harmless extra wakeup check that will clears the bit. The generic bit-waitqueue infrastructure is no longer used for pages. Instead, waitqueues are used directly with a custom key type. The generic code was not flexible enough to have PageWaiters manipulation under the waitqueue lock (which simplifies concurrency). This improves the performance of page lock intensive microbenchmarks by 2-3%. Putting two bits in the same word opens the opportunity to remove the memory barrier between clearing the lock bit and testing the waiters bit, after some work on the arch primitives (e.g., ensuring memory operand widths match and cover both bits).
