* xprtrdma: Remove the RPCRDMA_REQ_F_PENDING flagChuck Lever2019-07-093-5/+1
| | | | | | | | | | | | Commit 9590d083c1bb ("xprtrdma: Use xprt_pin_rqst in rpcrdma_reply_handler") pins incoming RPC/RDMA replies so they can be left in the pending requests queue while they are being processed without introducing a race between ->buf_free and the transport's reply handler. Therefore RPCRDMA_REQ_F_PENDING is no longer necessary. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
* xprtrdma: Fix occasional transport deadlockChuck Lever2019-07-094-29/+20
| | | | | | | | | | | | | | | | | | | | | | | Under high I/O workloads, I've noticed that an RPC/RDMA transport occasionally deadlocks (IOPS goes to zero, and doesn't recover). Diagnosis shows that the sendctx queue is empty, but when sendctxs are returned to the queue, the xprt_write_space wake-up never occurs. The wake-up logic in rpcrdma_sendctx_put_locked is racy. I noticed that both EMPTY_SCQ and XPRT_WRITE_SPACE are implemented via an atomic bit. Just one of those is sufficient. Removing EMPTY_SCQ in favor of the generic bit mechanism makes the deadlock un-reproducible. Without EMPTY_SCQ, rpcrdma_buffer::rb_flags is no longer used and is therefore removed. Unfortunately this patch does not apply cleanly to stable. If needed, someone will have to port it and test it.

* xprtrdma: Replace use of xdr_stream_pos in rpcrdma_marshal_reqChuck Lever2019-07-091-3/+3
| | | | | | | | | | | | | | | | | | This is a latent bug. xdr_stream_pos works by subtracting xdr_stream::nwords from xdr_buf::len. But xdr_stream::nwords is not initialized by xdr_init_encode(). It works today only because all fields in rpcrdma_req::rl_stream are initialized to zero by rpcrdma_req_create, making the subtraction in xdr_stream_pos always a no-op. I found this issue via code inspection. It was introduced by commit 39f4cd9e9982 ("xprtrdma: Harden chunk list encoding against send buffer overflow"), but the code has changed enough since then that this fix can't be automatically applied to stable.

It is not expected to be a significant problem because it is in an error path that is almost never executed. Fixes: 7c8d9e7c8863 ("xprtrdma: Move Receive posting to ...

| * | pktgen: do not sleep with the thread lock held.Paolo Abeni2019-06-061-0/+11

The above can blocks indefinitely any other pktgen command and any (even unrelated) netdevice removal - as the pktgen netdev notifier acquires the same lock. The issue is demonstrated by the following script, reported by Matteo: ip -b - <<'EOF' link add type dummy link add type veth link set dummy0 up EOF modprobe pktgen echo reset >/proc/net/pktgen/pgctrl { echo rem_device_all echo add_device dummy0 } >/proc/net/pktgen/kpktgend_0 echo count 0 >/proc/net/pktgen/dummy0 echo start >/proc/net/pktgen/pgctrl & sleep 1 rmmod veth Fix the above releasing the thread lock around the sleep call. Additionally we must prevent racing with forcefull rmmod - as the thread lock no more protects from them. Instead, acquire a self-reference before waiting for any thread. As a side effect, running rmmod pktgen while some thread is running now fails with "module in use" error, before this patch such command hanged indefinitely. Note: the issue predates the commit reported in the fixes tag, but this fix can't be applied before the mentioned commit. v1 -> v2: - no need to check for thread existence after flipping the lock, pktgen threads are freed only at net exit time - Fixes: 6146e6a43b35 ("[PKTGEN]: Removes thread_{un,}lock() macros.")

A workaround is to use IPPROTO_RAW instead of IPPROTO_ICMPV6. The failure happens because 2 bytes are eaten from the msghdr by rawv6_probe_proto_opt() starting from commit 19e3c66b52ca ("ipv6 equivalent of "ipv4: Avoid reading user iov twice after raw_probe_proto_opt""), but at that time it was not a problem because IPV6_HDRINCL was not yet introduced.

There is no restriction about what the kernel drivers can or cannot do with the open ethtool_regs structure. They usually set regs->version and ignore regs->len or set it to the same size as ops->get_regs_len(). But if userspace allocates a smaller buffer for the registers dump, we would cause a userspace buffer overflow in the final copy_to_user() call, which uses the regs.len value potentially reset by the driver. To fix this, make this case obvious and store regs.len before calling ops->get_regs(), to only copy as much data as requested by userspace, up to the value returned by ops->get_regs_len(). While at it, remove the redundant check for non-null regbuf. Signed-off-by: Vivien Didelot <vivien.didelot@gmail.com> Reviewed-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

This patch updates the IPv4 UDP multicast logic to match the unicast VRF logic (in compute_score()), as well as the IPv6 mcast logic (in __udp_v6_is_mcast_sock()). The particular case I noticed was DHCP discover packets going to the 255.255.255.255 address, which are handled by __udp4_lib_mcast_deliver(). The previous code meant that running multiple different DHCP server or relay agent instances across VRFs did not work correctly - any server/relay agent in the default VRF received DHCP discover packets for all other VRFs.

| * | net/tls: replace the sleeping lock around RX resync with a bit lockJakub Kicinski2019-06-041-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 38030d7cb779 ("net/tls: avoid NULL-deref on resync during device removal") tried to fix a potential NULL-dereference by taking the context rwsem. Unfortunately the RX resync may get called from soft IRQ, so we can't use the rwsem to protect from the device disappearing. Because we are guaranteed there can be only one resync at a time (it's called from strparser) use a bit to indicate resync is busy and make device removal wait for the bit to get cleared. Note that there is a leftover "flags" field in struct tls_context already.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rollover used to use a complex RCU mechanism for assignment, which had a race condition. The below patch fixed the bug and greatly simplified the logic. The feature depends on fanout, but the state is private to the socket. Fanout_release returns f only when the last member leaves and the fanout struct is to be freed. Destroy rollover unconditionally, regardless of fanout state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to a confusion I thought that eth_type_trans() was called by the network stack whereas it can actually be called by network drivers to figure out the skb protocol and next packet_type handlers. In light of the above, it is not safe to store the frame type from the DSA tagger's .filter callback (first entry point on RX path), since GRO is yet to be invoked on the received traffic. Hence it is very likely that the skb->cb will actually get overwritten between eth_type_trans() and the actual DSA packet_type handler. Of course, what this patch fixes is the actual overwriting of the SJA1105_SKB_CB(skb)->type field from the GRO layer, which made all frames be seen as SJA1105_FRAME_TYPE_NORMAL (0).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The addition of rpc_check_timeout() to call_decode causes an Oops when the RPCSEC_GSS credential is rejected. The reason is that rpc_decode_header() will call xprt_release() in order to free task->tk_rqstp, which is needed by rpc_check_timeout() to check whether or not we should exit due to a soft timeout. The fix is to move the call to xprt_release() into call_decode() so we can perform it after rpc_check_timeout().

For example: struct foo { int stuff; struct boo entry[]; }; instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.
