2017-03-21tcp: mark skbs with SCM_TIMESTAMPING_OPT_STATSSoheil Hassas Yeganeh3-7/+14
SOF_TIMESTAMPING_OPT_STATS can be enabled and disabled while packets are collected on the error queue. So, checking SOF_TIMESTAMPING_OPT_STATS in sk->sk_tsflags is not enough to safely assume that the skb contains OPT_STATS data. Add a bit in sock_exterr_skb to indicate whether the skb contains opt_stats data.

2017-03-21tcp: fix SCM_TIMESTAMPING_OPT_STATS for normal skbsSoheil Hassas Yeganeh2-1/+22
__sock_recv_timestamp can be called for both normal skbs (for receive timestamps) and for skbs on the error queue (for transmit timestamps). Commit 1c885808e456 (tcp: SOF_TIMESTAMPING_OPT_STATS option for SO_TIMESTAMPING) assumes any skb passed to __sock_recv_timestamp are from the error queue, containing OPT_STATS in the content of the skb. This results in accessing invalid memory or generating junk data. To fix this, set skb->pkt_type to PACKET_OUTGOING for packets on the error queue. This is safe because on the receive path on local sockets skb->pkt_type is never set to PACKET_OUTGOING. With that, copy OPT_STATS from a packet, only if its pkt_type is PACKET_OUTGOING.

2017-03-21net: vrf: Reset rt6i_idev in local dst after putDavid Ahern1-1/+3
The VRF driver takes a reference to the inet6_dev on the VRF device for its rt6_local dst when handling local traffic through the VRF device as a loopback. When the device is deleted the driver does a put on the idev but does not reset rt6i_idev in the rt6_info struct. When the dst is destroyed, dst_destroy calls ip6_dst_destroy which does a second put for what is essentially the same reference causing it to be prematurely freed. Reset rt6i_idev after the put in the vrf driver.

2017-03-21net: unix: properly re-increment inflight counter of GC discarded candidatesAndrey Ulanov1-8/+9
Dmitry has reported that a BUG_ON() condition in unix_notinflight() may be triggered by a simple code that forwards unix socket in an SCM_RIGHTS message. That is caused by incorrect unix socket GC implementation in unix_gc(). The GC first collects list of candidates, then (a) decrements their "children's" inflight counter, (b) checks which inflight counters are now 0, and then (c) increments all inflight counters back. (a) and (c) are done by calling scan_children() with inc_inflight or dec_inflight as the second argument. Commit 6209344f5a37 ("net: unix: fix inflight counting bug in garbage collector") changed scan_children() such that it no longer considers sockets that do not have UNIX_GC_CANDIDATE flag. It also added a block of code that that unsets this flag _before_ invoking scan_children(, dec_iflight, ). This may lead to incorrect inflight counters for some sockets. This change fixes this bug by changing order of operations: UNIX_GC_CANDIDATE is now unset only after all inflight counters are restored to the original state. kernel BUG at net/unix/garbage.c:149!

2017-03-16rxrpc: Ignore BUSY packets on old callsDavid Howells1-0/+4
If we receive a BUSY packet for a call we think we've just completed, the packet is handed off to the connection processor to deal with - but the connection processor doesn't expect a BUSY packet and so flags a protocol error. Fix this by simply ignoring the BUSY packet for the moment. The symptom of this may appear as a system call failing with EPROTO. This may be triggered by pressing ctrl-C under some circumstances. This comes about we abort calls due to interruption by a signal (which we shouldn't do, but that's going to be a large fix and mostly in fs/afs/). What happens is that we abort the call and may also abort follow up calls too (this needs offloading somehoe). So we see a transmission of something like the following sequence of packets: DATA for call N ABORT call N DATA for call N+1 ABORT call N+1 in very quick succession on the same channel. However, the peer may have deferred the processing of the ABORT from the call N to a background thread and thus sees the DATA message from the call N+1 coming in before it has cleared the channel. Thus it sends a BUSY packet[*]. [*] Note that some implementations (OpenAFS, for example) mark the BUSY packet with one plus the callNumber of the call prior to call N. Ordinarily, this would be call N, but there's no requirement for the calls on a channel to be numbered strictly sequentially (the number is required to increase). This is wrong and means that the callNumber in the BUSY packet should be ignored (it really ought to be N+1 since that's what it's in response to).

2017-03-16net/mlx4_core: Avoid delays during VF driver device shutdownJack Morgenstein3-0/+23
Some Hypervisors detach VFs from VMs by instantly causing an FLR event to be generated for a VF. In the mlx4 case, this will cause that VF's comm channel to be disabled before the VM has an opportunity to invoke the VF device's "shutdown" method. For such Hypervisors, there is a race condition between the VF's shutdown method and its internal-error detection/reset thread. The internal-error detection/reset thread (which runs every 5 seconds) also detects a disabled comm channel. If the internal-error detection/reset flow wins the race, we still get delays (while that flow tries repeatedly to detect comm-channel recovery). The cited commit fixed the command timeout problem when the internal-error detection/reset flow loses the race. This commit avoids the unneeded delays when the internal-error detection/reset flow wins.

Newer hardware does not provide a cumulative payload length when multiple descriptors are needed to handle the data. Once the MTU increases beyond the size that can be handled by a single descriptor, the SKB does not get built properly by the driver. The driver will now calculate the size of the data buffers used by the hardware. The first buffer of the first descriptor is for packet headers or packet headers and data when the headers can't be split. Subsequent descriptors in a multi-descriptor chain will not use the first buffer. The second buffer is used by all the descriptors in the chain for payload data. Based on whether the driver is processing the first, intermediate, or last descriptor it can calculate the buffer usage and build the SKB properly. Tested and verified on both old and new hardware.

2017-03-15fjes: Fix wrong netdevice feature flagsTaku Izumi1-1/+1
This patch fixes netdev->features for Extended Socket network device. Currently Extended Socket network device's netdev->feature claims NETIF_F_HW_CSUM, however this is completely wrong. There's no feature of checksum offloading. That causes invalid TCP/UDP checksum and packet rejection when IP forwarding from Extended Socket network device to other network device. NETIF_F_HW_CSUM should be omitted. Signed-off-by: Taku Izumi <izumi.taku@jp.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Commit 88ffbf3e03 switches to using rhashtables for glocks, hashing over the entire struct lm_lockname instead of its individual fields. On some architectures, struct lm_lockname contains a hole of uninitialized memory due to alignment rules, which now leads to incorrect hash values. Get rid of that hole.

Yuval Mintz says: ==================== qed: Fixes series This address several different issues in qed. The more significant portions: Patch #1 would cause timeout when qedr utilizes the highest CIDs availble for it [or when future qede adapters would utilize queues in some constellations]. Patch #4 fixes a leak of mapped addresses; When iommu is enabled, offloaded storage protocols might eventually run out of resources and fail to map additional buffers. Patches #6,#7 were missing in the initial iSCSI infrastructure submissions, and would hamper qedi's stability when it reaches out-of-order scenarios. ==================== Signed-off-by: David S.
