2023-08-13net: phy: fix IRQ-based wake-on-lan over hibernate / power offRussell King (Oracle)
Uwe reports: "Most PHYs signal WoL using an interrupt. So disabling interrupts [at shutdown] breaks WoL at least on PHYs covered by the marvell driver." Discussing with Ioana, the problem which was trying to be solved was: "The board in question is a LS1021ATSN which has two AR8031 PHYs that share an interrupt line. In case only one of the PHYs is probed and there are pending interrupts on the PHY#2 an IRQ storm will happen since there is no entity to clear the interrupt from PHY#2's registers. PHY#1's driver will get stuck in .handle_interrupt() indefinitely." Further confirmation that "the two AR8031 PHYs are on the same MDIO bus." With WoL using interrupts to wake the system, in such a case, the system will begin booting with an asserted interrupt. Thus, we need to cope with an interrupt asserted during boot. Solve this instead by disabling interrupts during PHY probe. This will ensure in Ioana's situation that both PHYs of the same type sharing an interrupt line on a common MDIO bus will have their interrupt outputs disabled when the driver probes the device, but before we hook in any interrupt handlers - thus avoiding the interrupt storm. A better fix would be for platform firmware to disable the interrupting devices at source during boot, before control is handed to the kernel.

There is no need for two more variables in hso_serial_write(). Switch to min_t() and eliminate those. Furthermore, the 'if-goto' is superfluous as memcpy() of zero count is a nop.

2023-08-10tun: avoid high-order page allocation for packet headerTahsin Erdogan
When gso.hdr_len is zero and a packet is transmitted via write() or writev(), all payload is treated as header which requires a contiguous memory allocation. This allocation request is harder to satisfy, and may even fail if there is enough fragmentation. Note that sendmsg() code path limits the linear copy length, so this change makes write()/writev() and sendmsg() paths more consistent.

2023-08-10net: stmmac: dwmac-imx: pause the TXC clock in fixed-linkShenwei Wang
When using a fixed-link setup, certain devices like the SJA1105 require a small pause in the TXC clock line to enable their internal tunable delay line (TDL). To satisfy this requirement, this patch temporarily disables the TX clock, and restarts it after a required period. This provides the required silent interval on the clock line for SJA1105 to complete the frequency transition and enable the internal TDLs. This action occurs before the link is built up, so it does not impact a normal device too. There is no need to identify if the connected device is an SJA1105 alike or not during the implementation. So far we have only enabled this feature on the i.MX93 platform.

2023-08-10virtio-net: Zero max_tx_vq field for VIRTIO_NET_CTRL_MQ_HASH_CONFIG caseHawkins Jiawei
Kernel uses `struct virtio_net_ctrl_rss` to save command-specific-data for both the VIRTIO_NET_CTRL_MQ_HASH_CONFIG and VIRTIO_NET_CTRL_MQ_RSS_CONFIG commands. According to the VirtIO standard, "Field reserved MUST contain zeroes. It is defined to make the structure to match the layout of virtio_net_rss_config structure, defined in 5.1.6.5.7.". Yet for the VIRTIO_NET_CTRL_MQ_HASH_CONFIG command case, the `max_tx_vq` field in struct virtio_net_ctrl_rss, which corresponds to the `reserved` field in struct virtio_net_hash_config, is not zeroed, thereby violating the VirtIO standard. This patch solves this problem by zeroing this field in virtnet_init_default_rss().

2023-08-10ibmvnic: Ensure login failure recovery is safe from other resetsNick Child
If a login request fails, the recovery process should be protected against parallel resets. It is a known issue that freeing and registering CRQ's in quick succession can result in a failover CRQ from the VIOS. Processing a failover during login recovery is dangerous for two reasons: 1. This will result in two parallel initialization processes, this can cause serious issues during login. 2. It is possible that the failover CRQ is received but never executed. We get notified of a pending failover through a transport event CRQ. The reset is not performed until a INIT CRQ request is received. Previously, if CRQ init fails during login recovery, then the ibmvnic irq is freed and the login process returned error. If failover_pending is true (a transport event was received), then the ibmvnic device would never be able to process the reset since it cannot receive the CRQ_INIT request due to the irq being freed. This leaved the device in a inoperable state. Therefore, the login failure recovery process must be hardened against these possible issues. Possible failovers (due to quick CRQ free and init) must be avoided and any issues during re-initialization should be dealt with instead of being propagated up the stack. This logic is similar to that of ibmvnic_probe().

2023-08-10ibmvnic: Do partial reset on login failureNick Child
Perform a partial reset before sending a login request if any of the following are true: 1. If a previous request times out. This can be dangerous because the VIOS could still receive the old login request at any point after the timeout. Therefore, it is best to re-register the CRQ's and sub-CRQ's before retrying. 2. If the previous request returns an error that is not described in PAPR. PAPR provides procedures if the login returns with partial success or aborted return codes (section L.5.1) but other values do not have a defined procedure. Previously, these conditions just returned error from the login function rather than trying to resolve the issue. This can cause further issues since most callers of the login function are not prepared to handle an error when logging in. This improper cleanup can lead to the device being permanently DOWN'd. For example, if the VIOS believes that the device is already logged in then it will return INVALID_STATE (-7). If we never re-register CRQ's then it will always think that the device is already logged in. This leaves the device inoperable. The partial reset involves freeing the sub-CRQs, freeing the CRQ then registering and initializing a new CRQ and sub-CRQs. This essentially restarts all communication with VIOS to allow for a fresh login attempt that will be unhindered by any previous failed attempts.

2023-08-10ibmvnic: Handle DMA unmapping of login buffs in release functionsNick Child
Rather than leaving the DMA unmapping of the login buffers to the login response handler, move this work into the login release functions. Previously, these functions were only used for freeing the allocated buffers. This could lead to issues if there are more than one outstanding login buffer requests, which is possible if a login request times out. If a login request times out, then there is another call to send login. The send login function makes a call to the login buffer release function. In the past, this freed the buffers but did not DMA unmap. Therefore, the VIOS could still write to the old login (now freed) buffer. It is for this reason that it is a good idea to leave the DMA unmap call to the login buffers release function. Since the login buffer release functions now handle DMA unmapping, remove the duplicate DMA unmapping in handle_login_rsp().
