From 1492623e837fe7ca6296f7f5411328307e242771 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 29 Dec 2018 17:42:22 +0100 Subject: octeontx2-af: Fix a resource leak in an error handling path in 'cgx_probe()' If an error occurs after the call to 'pci_alloc_irq_vectors()', we must call 'pci_free_irq_vectors()' in order to avoid a resource leak.

So allocating resources using devm_*() with these devices won't provide a cleanup path for these resources when the caller fails. This patch fixes them.

The flag phydev->supported is 0x6ff when hns modules is loaded, so will not change Fiber Port power(Reference to marvell.c), which is power on at default. Then the flag phydev->supported is changed to 0x6f, so Fiber Port power is off when removing hns modules. When hns modules installed again, the flag phydev->supported is default value 0x6ff, so will not change Fiber Port power(now is off), causing mac link not up problem.

The problem was in selecting MDIO_DEVICE instead of the preferred PHYLIB Kconfig option. The reason being that MDIO_DEVICE had a dependency on PHYLIB and would be compiled as a module when PHYLIB was a module, no matter whether ixgbe was compiled into the kernel.

The crash occurs because dma_alloc_coherent() returns one value in mlx4_alloc_icm_coherent(), but a different value is passed to dma_free_coherent() in mlx4_free_icm_coherent(). In turn this is because when allocated, that pointer is passed to sg_set_buf() to record it, then when freed it is re-calculated by calling lowmem_page_address(sg_page()) which returns a different value. Solve this by recording the value that dma_alloc_coherent() returns, and passing this to dma_free_coherent(). This patch is roughly equivalent to commit 378efe798ecf ("RDMA/hns: Get rid of page operation after dma_alloc_coherent").

This happens because the multicast router implementation in Spectrum-2 relies on ACLs. Taking the RTNL lock upon driver removal is useless since the driver first removes its ports and unregisters from notifiers so concurrent writes cannot happen at that time. The assertions were originally put as a reminder for future work involving ERP background optimization, but having these assertions only during addition serves this purpose as well. Therefore remove the ASSERT_RTNL() in both places related to ERP and Bloom filter removal.

Additionally, the driver does not properly check for and create a clause 45 MDIO command. Check the supplied MDIO register to determine if the request is a clause 45 operation (MII_ADDR_C45). For a clause 45 operation, extract the device address and register number from the supplied MDIO register and use them to set the MDIO command request device address and register number fields. For a clause 22 operation, the MDIO request device address is set to zero and the MDIO command request register number is set to the supplied MDIO register.

The device then tries to post a CQE (completion queue element) that contains various metadata (e.g., ingress port) about the packet to a CQ (completion queue). In case the device managed to consume a WQE, but did not manage to post the corresponding CQE, it will get stuck. This unlikely situation can be triggered due to the scheme the driver is currently using to process CQEs. The driver will consume up to 512 CQEs at a time and after processing each corresponding WQE it will ring the RDQ's doorbell, letting the device know that a new WQE was posted for it to consume. Only after processing all the CQEs (up to 512), the driver will ring the CQ's doorbell, letting the device know that new ones can be posted. Fix this by having the driver ring the CQ's doorbell for every processed CQE, but before ringing the RDQ's doorbell. This guarantees that whenever we post a new WQE, there is a corresponding CQE available. Copy the currently processed CQE to prevent the device from overwriting it with a new CQE after ringing the doorbell. Note that the driver still arms the CQ only after processing all the pending CQEs, so that interrupts for this CQ will only be delivered after the driver finished its processing. Before commit 8404f6f2e8ed ("mlxsw: pci: Allow to use CQEs of version 1 and version 2") the issue was virtually impossible to trigger since the number of CQEs was twice the number of WQEs and the number of CQEs processed at a time was equal to the number of available WQEs.

This implicit action sets a dummy FID to the packet and is used as part of a design for trapping unmatched flows in OVS. While this implicit FID setting action is supposed to be a NOP when a redirect action is added, in Spectrum-2 the FID record is consulted as the dummy FID index is an 802.1D FID index and the packet is dropped instead of being redirected. Set the dummy FID index value to be within 802.1Q range. This satisfies both Spectrum-1 which ignores the FID and Spectrum-2 which identifies it as an 802.1Q FID and will then follow the redirect action.

This worked fine if a single PF existed that registered one callback for the tunnel netdev of interest. However, if multiple PFs are in place then the 2nd PF tries to register with the same tunnel netdev identifier. This leads to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the rpriv pointer as the identifier for netdev indirect block cb registry, allowing each PF to register a unique callback per tunnel netdev. For block cb registry, the same PF may register multiple cbs to the same block if using TC shared blocks. Instead of the rpriv, use the pointer to the allocated indr_priv data as the identifier here. This means that there can be a unique block callback for each PF/tunnel netdev combo.

However, re-programming the FW doesn't work, unless a power cycle of the WiFi-chip is made in-between the programmings. To conform to this requirement and to fix the regression in a simple way, let's start by allowing that the SDIO card (WiFi-chip) may stay powered on (runtime resumed) when wl12xx_sdio_power_off() returns. The intent with the current code is to treat this scenario as an error, but unfortunate this doesn't work as expected, so let's fix this. The other part is to guarantee that a power cycle of the SDIO card has been completed when wl12xx_sdio_power_on() returns, as to allow the FW programming to succeed. However, relying solely on runtime PM to deal with this isn't sufficient. For example, userspace may prevent runtime suspend via sysfs for the device that represents the SDIO card, leading to that the mmc core also keeps it powered on. For this reason, let's instead do a brute force power cycle in wl12xx_sdio_power_on().

In order to allow this checksum to be received by the host descriptor data needs to be enlarged by 2 bytes to accommodate the checksum. In the case of MTU-sized packets without a VLAN tag the checksum were already accommodated by virtue of the space reserved for the VLAN tag. However, a packet of MTU-size with a VLAN tag consumed all packet data space provided by a descriptor leaving no space for the trailing checksum. This was not detected by the driver which incorrectly used the last two bytes of packet data as the checksum and truncate the packet by two bytes. This resulted all such packets being dropped. A work around is to disable RX checksum offload # ethtool -K eth0 rx off This patch resolves this problem by increasing the size available for packet data in RX descriptors by two bytes. Tested on R-Car E3 (r8a77990) ES1.0 based Ebisu-4D board v2 * Use sizeof(__sum16) directly rather than adding a driver-local #define for the size of the checksum provided by the hw (2 bytes).

Thus, a non-zero return should be treated as a -EFAULT error (as is done elsewhere in the kernel). However, mlx4_init_user_cqes() error handling simply returns the number of bytes not copied (instead of -EFAULT). Note, though, that this is a harmless bug: procedure mlx4_alloc_cq() (which is the only caller of mlx4_init_user_cqes()) treats any non-zero return as an error, but that returned error value is processed internally, and not passed further up the call stack.

But VF interfaces being in promiscuous mode should have caused adapter to accept all the unknown ucast packets. Later, it was found that driver doesn't really configure tx promiscuous mode settings to accept all unknown unicast macs. This patch fixes tx promiscuous mode settings to accept all unknown/unmatched unicast macs and works out the scenario. Signed-off-by: Manish Chopra Signed-off-by: Ariel Elior Signed-off-by: David S.

This is bogus since the queue has xdp_frames, not sk_buffs, thus mangled device tx bytes counters because skb->len is meaningless value, and even triggered oops due to general protection fault on freeing them. Since xdp send queues do not aquire locks, old xdp_frames should be freed only in virtnet_xdp_xmit(), so just skip free_old_xmit_skbs() for xdp send queues. Similarly virtnet_poll_tx() called free_old_xmit_skbs(). This NAPI handler is called even without calling start_xmit() because cb for tx is by default enabled. Once the handler is called, it enabled the cb again, and then the handler would be called again. We don't need this handler for XDP, so don't enable cb as well as not calling free_old_xmit_skbs(). Also, we need to disable tx NAPI when disabling XDP, so virtnet_poll_tx() can safely access curr_queue_pairs and xdp_queue_pairs, which are not atomically updated while disabling XDP.

Thus we need to handle both forms (xdp_frames and sk_buffs) regardless of XDP setting. One way to trigger this problem is to disable XDP when napi_tx is enabled. In that case, virtnet_xdp_set() calls virtnet_napi_enable() which kicks NAPI. The NAPI handler will call virtnet_poll_cleantx() which invokes free_old_xmit_skbs() for queues which have been used by XDP.

The ipvlan master device sits on top of a bond device and hostns traffic to kube-apiserver (also running in hostns) is DNATed from 10.152.183.1:443 to 139.178.29.207:37573 where the latter is the address of the bond0. While in l3 mode, a curl to https://10.152.183.1:443 or to https://139.178.29.207:37573 works fine from hostns, neither of them do in case of l3s. In the latter only a curl to https://127.0.0.1:37573 appeared to work where for local addresses of bond0 I saw kernel suddenly starting to emit ARP requests to query HW address of bond0 which remained unanswered and neighbor entries in INCOMPLETE state. These ARP requests only happen while in l3s. Debugging this further, I found the issue is that l3s mode is piggy- backing on l3 master device, and in this case local routes are using l3mdev_master_dev_rcu(dev) instead of net->loopback_dev as per commit f5a0aab84b74 ("net: ipv4: dst for local input routes should use l3mdev if relevant") and 5f02ce24c269 ("net: l3mdev: Allow the l3mdev to be a loopback"). I found that reverting them back into using the net->loopback_dev fixed ipvlan l3s connectivity and got everything working for the CNI. Now judging from 4fbae7d83c98 ("ipvlan: Introduce l3s mode") and the l3mdev paper in [0] the only sole reason why ipvlan l3s is relying on l3 master device is to get the l3mdev_ip_rcv() receive hook for setting the dst entry of the input route without adding its own ipvlan specific hacks into the receive path, however, any l3 domain semantics beyond just that are breaking l3s operation. Note that ipvlan also has the ability to dynamically switch its internal operation from l3 to l3s for all ports via ipvlan_set_port_mode() at runtime. In any case, l3 vs l3s soley distinguishes itself by 'de-confusing' netfilter through switching skb->dev to ipvlan slave device late in NF_INET_LOCAL_IN before handing the skb to L4. Minimal fix taken here is to add a IFF_L3MDEV_RX_HANDLER flag which, if set from ipvlan setup, gets us only the wanted l3mdev_l3_rcv() hook without any additional l3mdev semantics on top. This should also have minimal impact since dev->priv_flags is already hot in cache. With this set, l3s mode is working fine and I also get things like masquerading pod traffic on the ipvlan master properly working.

After the NIC sends this packet, the PHY will reply with a timestamp for that TX packet. If the cable is pulled at the right time I don't see that packet. It might gets flushed as part of queue shutdown on NIC's side. Once the link is up again then after the next sendmsg() we enqueue another skb in dp83640_txtstamp() and have two on the list. Then the PHY will send a reply and decode_txts() attaches it to the first skb on the list. No crash occurs since refcounting works but we are one packet behind. linuxptp/ptp4l usually closes the socket and opens a new one (in such a timeout case) so those "stale" replies never get there. However it does not resume normal operation anymore. Purge old skbs in decode_txts(). Fixes: cb646e2b02b2 ("ptp: Added a clock driver for the National Semiconductor PHYTER.")

However, when the upstream device is delayed, we currently may end up probing the module before the upstream device is available, and lose the module_insert() call. Avoid this by holding off probing the module until the SFP bus is properly connected to both the SFP socket driver and the upstream driver. Signed-off-by: Russell King Signed-off-by: David S.

At device dismantle phase, core networking clears IFF_UP and flush_all_backlogs() is called after rcu grace period to make sure no incoming packet might be in a cpu backlog and still referencing the device. Most drivers call netif_rx() from their interrupt handler, and since the interrupts are disabled at device dismantle, netif_rx() does not have to check dev->flags & IFF_UP Virtual drivers do not have this guarantee, and must therefore make the check themselves.

Fortunately the padding octets are usually zero's, which don't affect checksum. However, it is not guaranteed. For example, switches might choose to make other use of these octets. This repeatedly causes kernel hardware checksum fault. Prior to the cited commit below, skb checksum was forced to be CHECKSUM_NONE when padding is detected. After it, we need to keep skb->csum updated. However, fixing up CHECKSUM_COMPLETE requires to verify and parse IP headers, it does not worth the effort as the packets are so small that CHECKSUM_COMPLETE has no significant advantage. Future work: when reporting checksum complete is not an option for IP non-TCP/UDP packets, we can actually fallback to report checksum unnecessary, by looking at cqe IPOK bit.

Then, the indirection table should be built according to the new number of channels. Currently, such build is preformed independently of whether the channels opening is successful, and is not reverted on failure. The bug is caused due to removal of rss params from channels struct and moving it to priv struct. That change cause to independency between channels and rss params. This causes a crash on a later point, when accessing rqn of a non existing channel. This patch fixes it by moving the indirection table build right before switching the priv channels to new channels struct, after the new set of channels was successfully opened.

If one enables the use of hardware interrupts in the device tree for the 88E6341, it is possible to miss an edge. When this happens, the INTn pin on the Marvell switch is stuck low and no further interrupts occur. I found after adding debug statements to mv88e6xxx_g1_irq_thread_work() that there is a race in handling device interrupts (e.g. PHY link interrupts). Some interrupts are directly cleared by reading the Global 1 status register. However, the device interrupt flag, for example, is not cleared until all the unmasked SERDES and PHY ports are serviced. This is done by reading the relevant SERDES and PHY status register. The code only services interrupts whose status bit is set at the time of reading its status register. If an interrupt event occurs after its status is read and before all interrupts are serviced, then this event will not be serviced and the INTn output pin will remain low. This is not a problem with polling or level interrupts since the handler will be called again to process the event. However, it's a big problem when using level interrupts. The fix presented here is to add a loop around the code servicing switch interrupts. If any pending interrupts remain after the current set has been handled, we loop and process the new set. If there are no pending interrupts after servicing, we are sure that INTn has gone high and we will get an edge when a new event occurs. Tested on espressobin board.

The ds->ports[] array is used inside the dsa_is_user_port() and dsa_is_cpu_port() functions.
