Chris Packham says: ==================== net: dsa: mv88e6xxx: serdes link without phy This small series gets my hardware into a working state. The key points are to make sure we don't force the link and that we ask the MAC for the link status. I also have updated my dts to say `phy-mode = "1000base-x";` and `managed = "in-band-status";` I've dropped the patch for the 88E6123 as it's a distraction and I lack hardware to do any proper testing with it. Earlier versions are on the mailing list if anyone wants to pick it up in the future. I notice there's a series for mv88e6393x circulating on the netdev mailing list. As patch #1 is adding a new device specific op either this series will need updating to cover the mv88e6393x or the mv88e6393x series will need updating for the new op depenting on which lands first. ==================== Link: https://lore.kernel.org/r/20201124043440.28400-1-chris.packham@alliedtelesis.co.nzSigned-off-by:

If the underlying read operation failed we would end up writing stale data to the supplied buffer. This would end up with the last successfully read value repeating. Fix this by only writing the data when we know the read was good. This will mean that failed values will return 0xffff. Signed-off-by:

The MV88E6097 presents the serdes interrupts for ports 8 and 9 via the Switch Global 2 registers. There is no additional layer of enablinh/disabling the serdes interrupts like other mv88e6xxx switches. Even though most of the serdes behaviour is the same as the MV88E6185 that chip does not provide interrupts for serdes events so unlike earlier commits the functions added here are specific to the MV88E6097.

When a port is configured with 'managed = "in-band-status"' switch chips like the 88E6390 need to propagate the SERDES link state to the MAC because the link state is not correctly detected. This causes problems on the 88E6185/88E6097 where the link partner won't see link state changes because we're forcing the link. To address this introduce a new device specific op port_sync_link() and push the logic from mv88e6xxx_mac_link_up() into that. Provide an implementation for the 88E6185 like devices which doesn't force the link. Signed-off-by:

Use napi_consume_skb() to assert the case when it is not called in a atomic softirq context. Signed-off-by:
Yunsheng Lin <linyunsheng@huawei.com> Signed-off-by:
-
Yunsheng Lin authored
The current semantic for napi_consume_skb() is that caller need to provide non-zero budget when calling from NAPI context, and breaking this semantic will cause hard to debug problem, because _kfree_skb_defer() need to run in atomic context in order to push the skb to the particular cpu' napi_alloc_cache atomically. So add the lockdep_assert_in_softirq() to assert when the running context is not in_softirq, in_softirq means softirq is serving or BH is disabled, which has a ambiguous semantics due to the BH disabled confusion, so add a comment to emphasize that. And the softirq context can be interrupted by hard IRQ or NMI context, lockdep_assert_in_softirq() need to assert about hard IRQ or NMI context too. Suggested-by:

Extend MRP to support LC mode(link check) for the interconnect port. This applies only to the interconnect ring. Opposite to RC mode(ring check) the LC mode is using CFM frames to detect when the link goes up or down and based on that the userspace will need to react. One advantage of the LC mode over RC mode is that there will be fewer frames in the normal rings. Because RC mode generates InTest on all ports while LC mode sends CFM frame only on the interconnect port. All 4 nodes part of the interconnect ring needs to have the same mode. And it is not possible to have running LC and RC mode at the same time on a node. Whenever the MIM starts it needs to detect the status of the other 3 nodes in the interconnect ring so it would send a frame called InLinkStatus, on which the clients needs to reply with their link status. This patch adds InLinkStatus frame type and extends existing rules on how to forward this frame. Acked-by:

On close this timer might be scheduled. mptcp uses sk_reset_timer for this, so the a reference on the mptcp socket is taken. This causes a refcount leak which can for example be reproduced with 'mp_join_server_v4.pkt' from the mptcp-packetdrill repo. The leak has nothing to do with join requests, v1_mp_capable_bind_no_cs.pkt works too when replacing the last ack mpcapable to v1 instead of v0. unreferenced object 0xffff888109bba040 (size 2744): comm "packetdrill", [..] backtrace: [..] sk_prot_alloc.isra.0+0x2b/0xc0 [..] sk_clone_lock+0x2f/0x740 [..] mptcp_sk_clone+0x33/0x1a0 [..] subflow_syn_recv_sock+0x2b1/0x690 [..] Fixes: e16163b6 ("mptcp: refactor shutdown and close") Cc: Davide Caratti <dcaratti@redhat.com> Signed-off-by:Florian Westphal <fw@strlen.de> Acked-by:

The rtl8211f supports downshift and before commit 5502b218 ("net: phy: use phy_resolve_aneg_linkmode in genphy_read_status") the read-back of register MII_CTRL1000 was used to detect the negotiated link speed. The code added in commit d445dff2 ("net: phy: realtek: read actual speed to detect downshift") is working fine also for this phy and it's trivial re-using it to restore the downshift detection on rtl8211f. Add the phy specific read_status() pointing to the existing function rtlgen_read_status(). Signed-off-by:

Ioana Ciornei says: ==================== net: phy: add support for shared interrupts (part 3) This patch set aims to actually add support for shared interrupts in phylib and not only for multi-PHY devices. While we are at it, streamline the interrupt handling in phylib. For a bit of context, at the moment, there are multiple phy_driver ops that deal with this subject: - .config_intr() - Enable/disable the interrupt line. - .ack_interrupt() - Should quiesce any interrupts that may have been fired. It's also used by phylib in conjunction with .config_intr() to clear any pending interrupts after the line was disabled, and before it is going to be enabled. - .did_interrupt() - Intended for multi-PHY devices with a shared IRQ line and used by phylib to discern which PHY from the package was the one that actually fired the interrupt. - .handle_interrupt() - Completely overrides the default interrupt handling logic from phylib. The PHY driver is responsible for checking if any interrupt was fired by the respective PHY and choose accordingly if it's the one that should trigger the link state machine. From my point of view, the interrupt handling in phylib has become somewhat confusing with all these callbacks that actually read the same PHY register - the interrupt status. A more streamlined approach would be to just move the responsibility to write an interrupt handler to the driver (as any other device driver does) and make .handle_interrupt() the only way to deal with interrupts. Another advantage with this approach would be that phylib would gain support for shared IRQs between different PHY (not just multi-PHY devices), something which at the moment would require extending every PHY driver anyway in order to implement their .did_interrupt() callback and duplicate the same logic as in .ack_interrupt(). The disadvantage of making .did_interrupt() mandatory would be that we are slightly changing the semantics of the phylib API and that would increase confusion instead of reducing it. What I am proposing is the following: - As a first step, make the .ack_interrupt() callback optional so that we do not break any PHY driver amid the transition. - Every PHY driver gains a .handle_interrupt() implementation that, for the most part, would look like below: irq_status = phy_read(phydev, INTR_STATUS); if (irq_status < 0) { phy_error(phydev); return IRQ_NONE; } if (!(irq_status & irq_mask)) return IRQ_NONE; phy_trigger_machine(phydev); return IRQ_HANDLED; - Remove each PHY driver's implementation of the .ack_interrupt() by actually taking care of quiescing any pending interrupts before enabling/after disabling the interrupt line. - Finally, after all drivers have been ported, remove the .ack_interrupt() and .did_interrupt() callbacks from phy_driver. This patch set is part 3 (and final) of the entire change set and it addresses the remaining PHY drivers that have not been migrated previosly. Also, it finally removed the .did_interrupt() and .ack_interrupt() callbacks since they are of no use anymore. I do not have access to most of these PHY's, therefore I Cc-ed the latest contributors to the individual PHY drivers in order to have access, hopefully, to more regression testing. ==================== Link: https://lore.kernel.org/r/20201123153817.1616814-1-ciorneiioana@gmail.comSigned-off-by: -

Now that all the PHY drivers have been migrated to directly implement the generic .handle_interrupt() callback for a seamless support of shared IRQs and all the .config_inter() implementations clear any pending interrupts, we can safely remove the two callbacks. With this patch, phylib has a proper support for shared IRQs (and not just for multi-PHY devices. A PHY driver must implement both the .handle_interrupt() and .config_intr() callbacks for the IRQs to be actually used. Signed-off-by:

In preparation of removing the .ack_interrupt() callback, we must replace its occurrences (aka phy_clear_interrupt), from the 2 places where it is called from (phy_enable_interrupts and phy_disable_interrupts), with equivalent functionality. This means that clearing interrupts now becomes something that the PHY driver is responsible of doing, before enabling interrupts and after clearing them. Make this driver follow the new contract. Also, add a comment describing the multiple step interrupt acknoledgement process. Signed-off-by:
