2014-12-08net: mvneta: fix Tx interrupt delaywilly tarreau
The mvneta driver sets the amount of Tx coalesce packets to 16 by default. Normally that does not cause any trouble since the driver uses a much larger Tx ring size (532 packets). But some sockets might run with very small buffers, much smaller than the equivalent of 16 packets. This is what ping is doing for example, by setting SNDBUF to 324 bytes rounded up to 2kB by the kernel. The problem is that there is no documented method to force a specific packet to emit an interrupt (eg: the last of the ring) nor is it possible to make the NIC emit an interrupt after a given delay. In this case, it causes trouble, because when ping sends packets over its raw socket, the few first packets leave the system, and the first 15 packets will be emitted without an IRQ being generated, so without the skbs being freed. And since the socket's buffer is small, there's no way to reach that amount of packets, and the ping ends up with "send: no buffer available" after sending 6 packets. Running with 3 instances of ping in parallel is enough to hide the problem, because with 6 packets per instance, that's 18 packets total, which is enough to grant a Tx interrupt before all are sent. The original driver in the LSP kernel worked around this design flaw by using a software timer to clean up the Tx descriptors. This timer was slow and caused terrible network performance on some Tx-bound workloads (such as routing) but was enough to make tools like ping work correctly. Instead here, we simply set the packet counts before interrupt to 1. This ensures that each packet sent will produce an interrupt. NAPI takes care of coalescing interrupts since the interrupt is disabled once generated. No measurable performance impact nor CPU usage were observed on small nor large packets, including when saturating the link on Tx, and this fixes tools like ping which rely on too small a send buffer. If one wants to increase this value for certain workloads where it is safe to do so, "ethtool -C $dev tx-frames" will override this default setting. This fix needs to be applied to stable kernels starting with 3.10. Tested-By: Maggie Mae Roxas <maggie.mae.roxas@gmail.com> Signed-off-by: Willy Tarreau <w@1wt.eu> Signed-off-by: David S.

2014-12-08tipc: simplify relationship between name table lock and node lockYing Xue
When tipc name sequence is published, name table lock is released before name sequence buffer is delivered to remote nodes through its underlying unicast links. However, when name sequence is withdrawn, the name table lock is held until the transmission of the removal message of name sequence is finished. During the process, node lock is nested in name table lock. To prevent node lock from being nested in name table lock, while withdrawing name, we should adopt the same locking policy of publishing name sequence: name table lock should be released before message is sent.

2014-12-08tipc: ensure all name sequences are properly protected with its lockYing Xue
TIPC internally created a name table which is used to store name sequences. Now there is a read-write lock - tipc_nametbl_lock to protect the table, and each name sequence saved in the table is protected with its private lock. When a name sequence is inserted or removed to or from the table, its members might need to change. Therefore, in normal case, the two locks must be held while TIPC operates the table. However, there are still several places where we only hold tipc_nametbl_lock without proprerly obtaining name sequence lock, which might cause the corruption of name sequence.

2014-12-08net-timestamp: allow reading recv cmsg on errqueue with origin tstampWillem de Bruijn
Allow reading of timestamps and cmsg at the same time on all relevant socket families. One use is to correlate timestamps with egress device, by asking for cmsg IP_PKTINFO. on AF_INET sockets, call the relevant function (ip_cmsg_recv). To avoid changing legacy expectations, only do so if the caller sets a new timestamping flag SOF_TIMESTAMPING_OPT_CMSG. on AF_INET6 sockets, IPV6_PKTINFO and all other recv cmsg are already returned for all origins. only change is to set ifindex, which is not initialized for all error origins. In both cases, only generate the pktinfo message if an ifindex is known. This is not the case for ACK timestamps. The difference between the protocol families is probably a historical accident as a result of the different conditions for generating cmsg in the relevant ip(v6)_recv_error function: ipv4: if (serr->ee.ee_origin == SO_EE_ORIGIN_ICMP) { ipv6: if (serr->ee.ee_origin != SO_EE_ORIGIN_LOCAL) { At one time, this was the same test bar for the ICMP/ICMP6 distinction. This is no longer true. Signed-off-by: Willem de Bruijn <willemb@google.com> ---- Changes v1 -> v2 large rewrite - integrate with existing pktinfo cmsg generation code - on ipv4: only send with new flag, to maintain legacy behavior - on ipv6: send at most a single pktinfo cmsg - on ipv6: initialize fields if not yet initialized The recv cmsg interfaces are also relevant to the discussion of whether looping packet headers is problematic. For v6, cmsgs that identify many headers are already returned. This patch expands that to v4. If it sounds reasonable, I will follow with patches 1. request timestamps without payload with SOF_TIMESTAMPING_OPT_TSONLY (http://patchwork.ozlabs.org/patch/366967/) 2. sysctl to conditionally drop all timestamps that have payload or cmsg from users without CAP_NET_RAW.
