This patch supports the following interrupts. - One interrupt for multiple (timestamp, error, gPTP) - One interrupt for emac - Four interrupts for dma queue (best effort rx/tx, network control rx/tx) This patch improve efficiency of the interrupt handler by adding the interrupt handler corresponding to each interrupt source described above. Additionally, it reduces the number of times of the access to EthernetAVB IF. Also this patch prevent this driver depends on the whim of a boot loader.

Soheil Hassas Yeganeh says: ==================== add TX timestamping via cmsg This patch series aim at enabling TX timestamping via cmsg. Currently, to occasionally sample TX timestamping on a socket, applications need to call setsockopt twice: first for enabling timestamps and then for disabling them. This is an unnecessary overhead. With cmsg, in contrast, applications can sample TX timestamps per sendmsg(). This patch series adds the code for processing SO_TIMESTAMPING for cmsg's of the SOL_SOCKET level, and adds the glue code for TCP, UDP, and RAW for both IPv4 and IPv6. This implementation supports overriding timestamp generation flags (i.e., SOF_TIMESTAMPING_TX_*) but not timestamp reporting flags. Applications must still enable timestamp reporting via setsockopt to receive timestamps. This series does not change existing timestamping behavior for applications that are using socket options. I will follow up with another patch to enable timestamping for active TFO (client-side TCP Fast Open) and also setting packet mark via cmsgs. Thanks! Changes in v2: - Replace u32 with __u32 in the documentation. Changes in v3: - Fix the broken build for L2TP (due to changes in IPv6). ==================== Signed-off-by: NDavid S.

Currently, SOL_TIMESTAMPING can only be enabled using setsockopt. This is very costly when users want to sample writes to gather tx timestamps. Add support for enabling SO_TIMESTAMPING via control messages by using tsflags added in `struct sockcm_cookie` (added in the previous patches in this series) to set the tx_flags of the last skb created in a sendmsg. With this patch, the timestamp recording bits in tx_flags of the skbuff is overridden if SO_TIMESTAMPING is passed in a cmsg. Please note that this is only effective for overriding the recording timestamps flags. Users should enable timestamp reporting (e.g., SOF_TIMESTAMPING_SOFTWARE | SOF_TIMESTAMPING_OPT_ID) using socket options and then should ask for SOF_TIMESTAMPING_TX_* using control messages per sendmsg to sample timestamps for each write.

Process socket-level control messages by invoking __sock_cmsg_send in ip6_datagram_send_ctl for control messages on the SOL_SOCKET layer. This makes sure whenever ip6_datagram_send_ctl is called for udp and raw, we also process socket-level control messages. This is a bit uglier than IPv4, since IPv6 does not have something like ipcm_cookie. Perhaps we can later create a control message cookie for IPv6? Note that this commit interprets new control messages that were ignored before. As such, this commit does not change the behavior of IPv6 control messages.

Accept SO_TIMESTAMPING in control messages of the SOL_SOCKET level as a basis to accept timestamping requests per write. This implementation only accepts TX recording flags (i.e., SOF_TIMESTAMPING_TX_HARDWARE, SOF_TIMESTAMPING_TX_SOFTWARE, SOF_TIMESTAMPING_TX_SCHED, and SOF_TIMESTAMPING_TX_ACK) in control messages. Users need to set reporting flags (e.g., SOF_TIMESTAMPING_OPT_ID) per socket via socket options. This commit adds a tsflags field in sockcm_cookie which is set in __sock_cmsg_send. It only override the SOF_TIMESTAMPING_TX_* bits in sockcm_cookie.tsflags allowing the control message to override the recording behavior per write, yet maintaining the value of other flags. This patch implements validating the control message and setting tsflags in struct sockcm_cookie. Next commits in this series will actually implement timestamping per write for different protocols.

Currently, to avoid a cache line miss for accessing skb_shinfo, tcp_ack_tstamp skips socket that do not have SOF_TIMESTAMPING_TX_ACK bit set in sk_tsflags. This is implemented based on an implicit assumption that the SOF_TIMESTAMPING_TX_ACK is set via socket options for the duration that ACK timestamps are needed. To implement per-write timestamps, this check should be removed and replaced with a per-packet alternative that quickly skips packets missing ACK timestamps marks without a cache-line miss. To enable per-packet marking without a cache line miss, use one bit in TCP_SKB_CB to mark a whether a SKB might need a ack tx timestamp or not. Further checks in tcp_ack_tstamp are not modified and work as before.

SOF_TIMESTAMPING_OPT_ID is set to get data-independent IDs to associate timestamps with send calls. For TCP connections, tp->snd_una is used as the starting point to calculate relative IDs. This socket option will fail if set before the handshake on a passive TCP fast open connection with data in SYN or SYN/ACK, since setsockopt requires the connection to be in the ESTABLISHED state. To address these, instead of limiting the option to the ESTABLISHED state, accept the SOF_TIMESTAMPING_OPT_ID option as long as the connection is not in LISTEN or CLOSE states.

To process cmsg's of the SOL_SOCKET level in addition to cmsgs of another level, protocols can call sock_cmsg_send(). This causes a double walk on the cmsghdr list, one for SOL_SOCKET and one for the other level.

Alexandre TORGUE says: ==================== Enhance stmmac driver to support GMAC4.x IP This is a subset of patch to enhance current stmmac driver to support new GMAC4.x chips. New set of callbacks is defined to support this new family: descriptors, dma, core. One of main changes of GMAC 4.xx IP is descriptors management. -descriptors are only used in ring mode. -A descriptor is composed of 4 32bits registers (no more extended descriptors) -descriptor mechanism (Tx for example, but it is exactly the same for RX): -useful registers: -DMA_CH#_TxDesc_Ring_Len: length of transmit descriptor ring -DMA_CH#_TxDesc_List_Address: start address of the ring -DMA_CH#_TxDesc_Tail_Pointer: address of the last descriptor to send + 1. -DMA_CH#_TxDesc_Current_App_TxDesc: address of the current descriptor -The descriptor Tail Pointer register contains the pointer to the descriptor address (N). The base address and the current descriptor decide the address of the current descriptor that the DMA can process. The descriptors up to one location less than the one indicated by the descriptor tail pointer (N-1) are owned by the DMA. The DMA continues to process the descriptors until the following condition occurs: "current descriptor pointer == Descriptor Tail pointer" Then the DMA goes into suspend mode. The application must perform a write to descriptor tail pointer register and update the tail pointer to have the following condition and to start a new transfer: "current descriptor pointer < Descriptor tail pointer" The DMA automatically wraps around the base address when the end of ring is reached. New features are available on IP: -TSO (TCP Segmentation Offload) for TX only -Split header: to have header and payload in 2 different buffers (not yet implemented) Below some throughput figures obtained on some boxes: iperf (mbps) -------------------------------------- tcp udp tx rx tx rx ----------------- GMAC4.x 935 930 750 800 Note: There is a change in 4.10a databook on bitfield mapping of DMA_CHANx_INTR_ENA register.

For non-SACK connections, cwnd is lowered to inflight plus 3 packets when the recovery ends. This is an optional feature in the NewReno RFC 2582 to reduce the potential burst when cwnd is "re-opened" after recovery and inflight is low. This feature is questionably effective because of PRR: when the recovery ends (i.e., snd_una == high_seq) NewReno holds the CA_Recovery state for another round trip to prevent false fast retransmits. But if the inflight is low, PRR will overwrite the moderated cwnd in tcp_cwnd_reduction() later regardlessly. So if a receiver responds bogus ACKs (i.e., acking future data) to speed up transfer after recovery, it can only induce a burst up to a window worth of data packets by acking up to SND.NXT. A restart from (short) idle or receiving streched ACKs can both cause such bursts as well. On the other hand, if the recovery ends because the sender detects the losses were spurious (e.g., reordering). This feature unconditionally lowers a reverted cwnd even though nothing was lost. By principle loss recovery module should not update cwnd. Further pacing is much more effective to reduce burst. Hence this patch removes the cwnd moderation feature. v2 changes: revised commit message on bogus ACKs and burst, and missing signature Signed-off-by: NMatt Mathis <mattmathis@google.com> Signed-off-by: NNeal Cardwell <ncardwell@google.com> Signed-off-by: NSoheil Hassas Yeganeh <soheil@google.com> Signed-off-by: NYuchung Cheng <ycheng@google.com> Signed-off-by: NDavid S.

The problem is that something (systemd) in dracut depends on CONFIG_FHANDLE, which adds open by file handle syscalls. While it is set in defconfigs it is very easy to miss when updating older configs because it is not default y. Make it default y and also depend on EXPERT, as dracut use is likely widespread.

Commit bb29902a ("oom, oom_reaper: protect oom_reaper_list using simpler way") has simplified the check for tasks already enqueued for the oom reaper by checking tsk->oom_reaper_list != NULL. This check is not sufficient because the tsk might be the head of the queue without any other tasks queued and then we would simply lockup looping on the same task. Fix the condition by checking for the head as well.
