Craig Gallek says: ==================== libbpf: support more map options The functional change to this series is the ability to use flags when creating maps from object files loaded by libbpf. In order to do this, the first patch updates the library to handle map definitions that differ in size from libbpf's struct bpf_map_def. For object files with a larger map definition, libbpf will continue to load if the unknown fields are all zero, otherwise the map is rejected. If the map definition in the object file is smaller than expected, libbpf will use zero as a default value in the missing fields. ==================== Acked-by: NAlexei Starovoitov <ast@kernel.org> Signed-off-by: NDavid S.

This library previously assumed a fixed-size map options structure. Any new options were ignored. In order to allow the options structure to grow and to support parsing older programs, this patch updates the maps section parsing to handle varying sizes. Object files with maps sections smaller than expected will have the new fields initialized to zero. Object files which have larger than expected maps sections will be rejected unless all of the unrecognized data is zero. This change still assumes that each map definition in the maps section is the same size.

Yuchung Cheng says: ==================== tcp: improving RACK cpu performance This patch set improves the CPU consumption of the RACK TCP loss recovery algorithm, in particular for high-speed networks. Currently, for every ACK in recovery RACK can potentially iterate over all sent packets in the write queue. On large BDP networks with non-trivial losses the RACK write queue walk CPU usage becomes unreasonably high. This patch introduces a new queue in TCP that keeps only skbs sent and not yet (s)acked or marked lost, in time order instead of sequence order. With that, RACK can examine this time-sorted list and only check packets that were sent recently, within the reordering window, per ACK. This is the fastest way without any write queue walks. The number of skbs examined per ACK is reduced by orders of magnitude. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Use the new time-ordered list to speed up RACK. The detection logic is identical. But since the list is chronologically ordered by skb_mstamp and contains only skbs not yet acked or sacked, RACK can abort the loop upon hitting skbs that were sent more recently. On YouTube servers this patch reduces the iterations on write queue by 40x. The improvement is even bigger with large BDP networks.

This patch adds a new queue (list) that tracks the sent but not yet acked or SACKed skbs for a TCP connection. The list is chronologically ordered by skb->skb_mstamp (the head is the oldest sent skb). This list will be used to optimize TCP Rack recovery, which checks an skb's timestamp to judge if it has been lost and needs to be retransmitted. Since TCP write queue is ordered by sequence instead of sent time, RACK has to scan over the write queue to catch all eligible packets to detect lost retransmission, and iterates through SACKed skbs repeatedly. Special cares for rare events: 1. TCP repair fakes skb transmission so the send queue needs adjusted 2. SACK reneging would require re-inserting SACKed skbs into the send queue. For now I believe it's not worth the complexity to make RACK work perfectly on SACK reneging, so we do nothing here. 3. Fast Open: currently for non-TFO, send-queue correctly queues the pure SYN packet. For TFO which queues a pure SYN and then a data packet, send-queue only queues the data packet but not the pure SYN due to the structure of TFO code. This is okay because the SYN receiver would never respond with a SACK on a missing SYN (i.e. SYN is never fast-retransmitted by SACK/RACK). In order to not grow sk_buff, we use an union for the new list and _skb_refdst/destructor fields. This is a bit complicated because we need to make sure _skb_refdst and destructor are properly zeroed before skb is cloned/copied at transmit, and before being freed.

Currently in the TCP code, the initialization sequence for cached metrics, congestion control, BPF, etc, after successful connection is very inconsistent. This introduces inconsistent bevhavior and is prone to bugs. The current call sequence is as follows: (1) for active case (tcp_finish_connect() case): tcp_mtup_init(sk); icsk->icsk_af_ops->rebuild_header(sk); tcp_init_metrics(sk); tcp_call_bpf(sk, BPF_SOCK_OPS_ACTIVE_ESTABLISHED_CB); tcp_init_congestion_control(sk); tcp_init_buffer_space(sk); (2) for passive case (tcp_rcv_state_process() TCP_SYN_RECV case): icsk->icsk_af_ops->rebuild_header(sk); tcp_call_bpf(sk, BPF_SOCK_OPS_PASSIVE_ESTABLISHED_CB); tcp_init_congestion_control(sk); tcp_mtup_init(sk); tcp_init_buffer_space(sk); tcp_init_metrics(sk); (3) for TFO passive case (tcp_fastopen_create_child()): inet_csk(child)->icsk_af_ops->rebuild_header(child); tcp_init_congestion_control(child); tcp_mtup_init(child); tcp_init_metrics(child); tcp_call_bpf(child, BPF_SOCK_OPS_PASSIVE_ESTABLISHED_CB); tcp_init_buffer_space(child); This commit uniforms the above functions to have the following sequence: tcp_mtup_init(sk); icsk->icsk_af_ops->rebuild_header(sk); tcp_init_metrics(sk); tcp_call_bpf(sk, BPF_SOCK_OPS_ACTIVE/PASSIVE_ESTABLISHED_CB); tcp_init_congestion_control(sk); tcp_init_buffer_space(sk); This sequence is the same as the (1) active case. We pick this sequence because this order correctly allows BPF to override the settings including congestion control module and initial cwnd, etc from the route, and then allows the CC module to see those settings.

Stefan Hajnoczi says: ==================== VSOCK: add sock_diag interface v3: * Rebased onto net-next/master and resolved Hyper-V transport conflict v2: * Moved tests to tools/testing/vsock/. I was unable to put them in selftests/ because they require manual setup of a VMware/KVM guest. * Moved to __vsock_in_bound/connected_table() to af_vsock.h * Fixed local variable ordering in Patch 4 There is currently no way for userspace to query open AF_VSOCK sockets. This means ss(8), netstat(8), and other utilities cannot display AF_VSOCK sockets. This patch series adds the netlink sock_diag interface for AF_VSOCK. Userspace programs sent a DUMP request including an sk_state bitmap to filter sockets based on their state (connected, listening, etc). The vsock_diag.ko module replies with information about matching sockets. This userspace ABI is defined in <linux/vm_sockets_diag.h>. The final patch adds a test suite that exercises the basic cases. Jorgen and Dexuan: I have only tested the virtio transport but this should also work for VMCI and Hyper-V. Please give it a shot if you have time. ==================== Signed-off-by: NDavid S.

This patch adds the sock_diag interface for querying sockets from userspace. Tools like ss(8) and netstat(8) can use this interface to list open sockets. The userspace ABI is defined in <linux/vm_sockets_diag.h> and includes netlink request and response structs. The request can query sockets based on their sk_state (e.g. listening sockets only) and the response contains socket information fields including the local/remote addresses, inode number, etc. This patch does not dump VMCI pending sockets because I have only tested the virtio transport, which does not use pending sockets. Support can be added later by extending vsock_diag_dump() if needed by VMCI users. Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

There are two state fields: socket->state and sock->sk_state. The socket->state field uses SS_UNCONNECTED, SS_CONNECTED, etc while the sock->sk_state typically uses values that match TCP state constants (TCP_CLOSE, TCP_ESTABLISHED). AF_VSOCK does not follow this convention and instead uses SS_* constants for both fields. The sk_state field will be exposed to userspace through the vsock_diag interface for ss(8), netstat(8), and other programs. This patch switches sk_state to TCP state constants so that the meaning of this field is consistent with other address families. Not just AF_INET and AF_INET6 use the TCP constants, AF_UNIX and others do too. The following mapping was used to convert the code: SS_FREE -> TCP_CLOSE SS_UNCONNECTED -> TCP_CLOSE SS_CONNECTING -> TCP_SYN_SENT SS_CONNECTED -> TCP_ESTABLISHED SS_DISCONNECTING -> TCP_CLOSING VSOCK_SS_LISTEN -> TCP_LISTEN In __vsock_create() the sk_state initialization was dropped because sock_init_data() already initializes sk_state to TCP_CLOSE.

There are three important fields that indicate the overall health and status of an array: dev_health, sync_ratio, and sync_action. They tell us the condition of the devices in the array, and the degree to which the array is synchronized. This commit fixes a condition that is reported incorrectly. When a member of the array is being rebuilt or a new device is added, the "recover" process is used to synchronize it with the rest of the array. When the process is complete, but the sync thread hasn't yet been reaped, it is possible for the state of MD to be: mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ] curr_resync_completed = <max dev size> (but not MaxSector) and all rdevs to be In_sync. This causes the 'array_in_sync' output parameter that is passed to rs_get_progress() to be computed incorrectly and reported as 'false' -- or not in-sync. This in turn causes the dev_health status characters to be reported as all 'a', rather than the proper 'A'. This can cause erroneous output for several seconds at a time when tools will want to be checking the condition due to events that are raised at the end of a sync process. Fix this by properly calculating the 'array_in_sync' return parameter in rs_get_progress(). Also, remove an unnecessary intermediate 'recovery_cp' variable in rs_get_progress().
