2023-07-06net: mscc: ocelot: fix oversize frame dropping for preemptible TCsVladimir Oltean
This switch implements Hold/Release in a strange way, with no control from the user as required by IEEE 802.1Q-2018 through Set-And-Hold-MAC and Set-And-Release-MAC, but rather, it emits HOLD requests implicitly based on the schedule. Namely, when the gate of a preemptible TC is about to close (actually QSYS::PREEMPTION_CFG.HOLD_ADVANCE octet times in advance of this event), the QSYS seems to emit a HOLD request pulse towards the MAC which preempts the currently transmitted packet, and further packets are held back in the queue system. This allows large frames to be squeezed through small time slots, because HOLD requests initiated by the gate events result in the frame being segmented in multiple fragments, the bit time of which is equal to the size of the time slot. It has been reported that the vsc9959_tas_guard_bands_update() logic breaks this, because it doesn't take preemptible TCs into account, and enables oversized frame dropping when the time slot doesn't allow a full MTU to be sent, but it does allow 2*minFragSize to be sent (128B). Packets larger than 128B are dropped instead of being sent in multiple fragments. Confusingly, the manual says: | For guard band, SDU calculation of a traffic class of a port, if | preemption is enabled (through 'QSYS::PREEMPTION_CFG.P_QUEUES') then | QSYS::PREEMPTION_CFG.HOLD_ADVANCE is used, otherwise | QSYS::QMAXSDU_CFG_*.QMAXSDU_* is used. but this only refers to the static guard band durations, and the QMAXSDU_CFG_* registers have dual purpose - the other being oversized frame dropping, which takes place irrespective of whether frames are preemptible or express. So, to fix the problem, we need to call vsc9959_tas_guard_bands_update() from ocelot_port_update_active_preemptible_tcs(), and modify the guard band logic to consider a different (lower) oversize limit for preemptible traffic classes.

2023-07-06net: mscc: ocelot: extend ocelot->fwd_domain_lock to cover ocelot->tas_lockVladimir Oltean
In a future commit we will have to call vsc9959_tas_guard_bands_update() from ocelot_port_update_active_preemptible_tcs(), and that will be impossible due to the AB/BA locking dependencies between ocelot->tas_lock and ocelot->fwd_domain_lock. Just like we did in commit 3ff468ef987e ("net: mscc: ocelot: remove struct ocelot_mm_state :: lock"), the only solution is to expand the scope of ocelot->fwd_domain_lock for it to also serialize changes made to the Time-Aware Shaper, because those will have to result in a recalculation of cut-through TCs, which is something that depends on the forwarding domain.

2023-07-05igc: Handle PPS start time programming for past time valuesAravindhan Gunasekaran
I225/6 hardware can be programmed to start PPS output once the time in Target Time registers is reached. The time programmed in these registers should always be into future. Only then PPS output is triggered when SYSTIM register reaches the programmed value. There are two modes in i225/6 hardware to program PPS, pulse and clock mode. There were issues reported where PPS is not generated when start time is in past. Example 1, "echo 0 0 0 2 0 > /sys/class/ptp/ptp0/period" In the current implementation, a value of '0' is programmed into Target time registers and PPS output is in pulse mode. Eventually an interrupt which is triggered upon SYSTIM register reaching Target time is not fired. Thus no PPS output is generated. Example 2, "echo 0 0 0 1 0 > /sys/class/ptp/ptp0/period" Above case, a value of '0' is programmed into Target time registers and PPS output is in clock mode. Here, HW tries to catch-up the current time by incrementing Target Time register. This catch-up time seem to vary according to programmed PPS period time as per the HW design. In my experiments, the delay ranged between few tens of seconds to few minutes. The PPS output is only generated after the Target time register reaches current time. In my experiments, I also observed PPS stopped working with below test and could not recover until module is removed and loaded again. 1) echo 0 <future time> 0 1 0 > /sys/class/ptp/ptp1/period 2) echo 0 0 0 1 0 > /sys/class/ptp/ptp1/period 3) echo 0 0 0 1 0 > /sys/class/ptp/ptp1/period After this PPS did not work even if i re-program with proper values. I could only get this back working by reloading the driver. This patch takes care of calculating and programming appropriate future time value into Target Time registers.

2023-07-05igc: Include the length/type field and VLAN tag in queueMaxSDUTan Tee Min
IEEE 802.1Q does not have clear definitions of what constitutes an SDU (Service Data Unit), but IEEE Std 802.3 clause 3.1.2 does define the MAC service primitives and clause 3.2.7 does define the MAC Client Data for Q-tagged frames. It shows that the mac_service_data_unit (MSDU) does NOT contain the preamble, destination and source address, or FCS. The MSDU does contain the length/type field, MAC client data, VLAN tag and any padding data (prior to the FCS). Thus, the maximum 802.3 frame size that is allowed to be transmitted should be QueueMaxSDU (MSDU) + 16 (6 byte SA + 6 byte DA + 4 byte FCS).

2023-07-05net/mlx5e: RX, Fix page_pool page fragment tracking for XDPDragos Tatulea
Currently mlx5e releases pages directly to the page_pool for XDP_TX and does page fragment counting for XDP_REDIRECT. RX pages from the page_pool are leaking on XDP_REDIRECT because the xdp core will release only one fragment out of MLX5E_PAGECNT_BIAS_MAX and subsequently the page is marked as "skip release" which avoids the driver release. A fix would be to take an extra fragment for XDP_REDIRECT and not set the "skip release" bit so that the release on the driver side can handle the remaining bias fragments. But this would be a shortsighted solution. Instead, this patch converges the two XDP paths (XDP_TX and XDP_REDIRECT) to always do fragment tracking. The "skip release" bit is no longer necessary for XDP.

2023-07-05net/mlx5e: Check for NOT_READY flag state after lockingVlad Buslov
Currently the check for NOT_READY flag is performed before obtaining the necessary lock.

2023-07-05igc: Fix TX Hang issue when QBV Gate is closedMuhammad Husaini Zulkifli
If a user schedules a Gate Control List (GCL) to close one of the QBV gates while also transmitting a packet to that closed gate, TX Hang will be happen. HW would not drop any packet when the gate is closed and keep queuing up in HW TX FIFO until the gate is re-opened. This patch implements the solution to drop the packet for the closed gate. This patch will also reset the adapter to perform SW initialization for each 1st Gate Control List (GCL) to avoid hang. This is due to the HW design, where changing to TSN transmit mode requires SW initialization. Intel Discrete I225/6 transmit mode cannot be changed when in dynamic mode according to Software User Manual Section 7.5.2.1. Subsequent Gate Control List (GCL) operations will proceed without a reset, as they already are in TSN Mode. Step to reproduce: DUT: 1) Configure GCL List with certain gate close. BASE=$(date +%s%N) tc qdisc replace dev $IFACE parent root handle 100 taprio \ num_tc 4 \ map 0 1 2 3 3 3 3 3 3 3 3 3 3 3 3 3 \ queues 1@0 1@1 1@2 1@3 \ base-time $BASE \ sched-entry S 0x8 500000 \ sched-entry S 0x4 500000 \ flags 0x2 2) Transmit the packet to closed gate.

2023-07-04net: dsa: sja1105: always enable the send_meta optionsVladimir Oltean
incl_srcpt has the limitation, mentioned in commit b4638af8885a ("net: dsa: sja1105: always enable the INCL_SRCPT option"), that frames with a MAC DA of 01:80:c2:xx:yy:zz will be received as 01:80:c2:00:00:zz unless PTP RX timestamping is enabled. The incl_srcpt option was initially unconditionally enabled, then that changed with commit 42824463d38d ("net: dsa: sja1105: Limit use of incl_srcpt to bridge+vlan mode"), then again with b4638af8885a ("net: dsa: sja1105: always enable the INCL_SRCPT option"). Bottom line is that it now needs to be always enabled, otherwise the driver does not have a reliable source of information regarding source_port and switch_id for link-local traffic (tag_8021q VLANs may be imprecise since now they identify an entire bridging domain when ports are not standalone). If we accept that PTP RX timestamping (and therefore, meta frame generation) is always enabled in hardware, then that limitation could be avoided and packets with any MAC DA can be properly received, because meta frames do contain the original bytes from the MAC DA of their associated link-local packet. This change enables meta frame generation unconditionally, which also has the nice side effects of simplifying the switch control path (a switch reset is no longer required on hwtstamping settings change) and the tagger data path (it no longer needs to be informed whether to expect meta frames or not - it always does).

2023-07-04pptp: Fix fib lookup calls.Guillaume Nault
PPTP uses pppox sockets (struct pppox_sock). These sockets don't embed an inet_sock structure, so it's invalid to call inet_sk() on them. Therefore, the ip_route_output_ports() call in pptp_connect() has two problems: * The tos variable is set with RT_CONN_FLAGS(sk), which calls inet_sk() on the pppox socket. * ip_route_output_ports() tries to retrieve routing flags using inet_sk_flowi_flags(), which is also going to call inet_sk() on the pppox socket. While PPTP doesn't use inet sockets, it's actually really layered on top of IP and therefore needs a proper way to do fib lookups. So let's define pptp_route_output() to get a struct rtable from a pptp socket. Let's also replace the ip_route_output_ports() call of pptp_xmit() for consistency. In practice, this means that: * pptp_connect() sets ->flowi4_tos and ->flowi4_flags to zero instead of using bits of unrelated struct pppox_sock fields. * pptp_xmit() now respects ->sk_mark and ->sk_uid. * pptp_xmit() now calls the security_sk_classify_flow() security hook, thus allowing to set ->flowic_secid. * pptp_xmit() now passes the pppox socket to xfrm_lookup_route().

2023-07-03wireguard: netlink: send staged packets when setting initial private keyJason A. Donenfeld
Packets bound for peers can queue up prior to the device private key being set. For example, if persistent keepalive is set, a packet is queued up to be sent as soon as the device comes up. However, if the private key hasn't been set yet, the handshake message never sends, and no timer is armed to retry, since that would be pointless. But, if a user later sets a private key, the expectation is that those queued packets, such as a persistent keepalive, are actually sent. So adjust the configuration logic to account for this edge case, and add a test case to make sure this works. Maxim noticed this with a wg-quick(8) config to the tune of: [Interface] PostUp = wg set %i private-key somefile [Peer] PublicKey = ... Endpoint = ... PersistentKeepalive = 25 Here, the private key gets set after the device comes up using a PostUp script, triggering the bug.

2023-06-29ibmvnic: Do not reset dql stats on NON_FATAL errNick Child
All ibmvnic resets, make a call to netdev_tx_reset_queue() when re-opening the device. netdev_tx_reset_queue() resets the num_queued and num_completed byte counters. These stats are used in Byte Queue Limit (BQL) algorithms. The difference between these two stats tracks the number of bytes currently sitting on the physical NIC. ibmvnic increases the number of queued bytes though calls to netdev_tx_sent_queue() in the drivers xmit function. When, VIOS reports that it is done transmitting bytes, the ibmvnic device increases the number of completed bytes through calls to netdev_tx_completed_queue(). It is important to note that the driver batches its transmit calls and num_queued is increased every time that an skb is added to the next batch, not necessarily when the batch is sent to VIOS for transmission. Unlike other reset types, a NON FATAL reset will not flush the sub crq tx buffers. Therefore, it is possible for the batched skb array to be partially full. So if there is call to netdev_tx_reset_queue() when re-opening the device, the value of num_queued (0) would not account for the skb's that are currently batched. Eventually, when the batch is sent to VIOS, the call to netdev_tx_completed_queue() would increase num_completed to a value greater than the num_queued. This causes a BUG_ON crash: ibmvnic 30000002: Firmware reports error, cause: adapter problem.
