2023-02-04ionic: missed doorbell workaroundAllen Hubbe6-4/+176
In one version of the HW there is a remote possibility that it will miss the doorbell ring. This adds a bit of protection to be sure we don't stall a queue from a missed doorbell.

2023-02-03net: phylink: move phy_device_free() to correctly release phy deviceClément Léger1-3/+2
After calling fwnode_phy_find_device(), the phy device refcount is incremented. Then, when the phy device is attached to a netdev with phy_attach_direct(), the refcount is also incremented but only decremented in the caller if phy_attach_direct() fails. Move phy_device_free() before the "if" to always release it correctly. Indeed, either phy_attach_direct() failed and we don't want to keep a reference to the phydev or it succeeded and a reference has been taken internally.

2023-02-03of/address: Return an error when no valid dma-ranges are foundMark Brown1-6/+15
Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range") converted the parsing of dma-range properties to use code shared with the PCI range parser. The intent was to introduce no functional changes however in the case where we fail to translate the first resource instead of returning -EINVAL the new code we return 0. Restore the previous behaviour by returning an error if we find no valid ranges, the original code only handled the first range but subsequently support for parsing all supplied ranges was added. This avoids confusing code using the parsed ranges which doesn't expect to successfully parse ranges but have only a list terminator returned, this fixes breakage with so far as I can tell all DMA for on SoC devices on the Socionext Synquacer platform which has a firmware supplied DT. A bisect identified the original conversion as triggering the issues there.

The reason is that a pointer to a string is passed to an inline assembly; this string however is located on the stack, while the instruction within the inline assembly expects a physicial address. Fix this by copying the string to a kmalloc'ed buffer. - The diag288_wdt watchdog module does not indicate that it accesses memory from an inline assembly, which it does. Add "memory" to the clobber list to prevent the compiler from optimizing code incorrectly away. - Pass size of the uncompressed kernel image to __decompress() call. Otherwise the kernel image decompressor may corrupt/overwrite an initrd. This was reported to happen on s390 after commit 2aa14b1ab2c4 ("zstd: import usptream v1.5.2"). * tag 's390-6.2-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/decompressor: specify __decompress() buf len to avoid overflow watchdog: diag288_wdt: fix __diag288() inline assembly watchdog: diag288_wdt: do not use stack buffers for hardware data

The code expect the PHY to be in power down which is only true after reset. Allow changes of the SGMII parameters more than once. Only power down when reconfiguring to avoid bouncing the link when there's no reason to - based on code from Russell King.

2023-02-02ata: libata: Fix sata_down_spd_limit() when no link speed is reportedDamien Le Moal1-1/+1
Commit 2dc0b46b5ea3 ("libata: sata_down_spd_limit should return if driver has not recorded sstatus speed") changed the behavior of sata_down_spd_limit() to return doing nothing if a drive does not report a current link speed, to avoid reducing the link speed to the lowest 1.5 Gbps speed. However, the change assumed that a speed was recorded before probing (e.g. before a suspend/resume) and set in link->sata_spd. This causes problems with adapters/drives combination failing to establish a link speed during probe autonegotiation. One example reported of this problem is an mvebu adapter with a 3Gbps port-multiplier box: autonegotiation fails, leaving no recorded link speed and no reported current link speed. Probe retries also fail as no action is taken by sata_set_spd() after each retry. Fix this by returning early in sata_down_spd_limit() only if we do have a recorded link speed, that is, if link->sata_spd is not 0. With this fix, a failed probe not leading to a recorded link speed is retried at the lower 1.5 Gbps speed, with the link speed potentially increased later on the second revalidate of the device if the device reports that it supports higher link speeds.

2023-02-02hv_netvsc: Fix missed pagebuf entries in netvsc_dma_map/unmap()Michael Kelley1-7/+2
netvsc_dma_map() and netvsc_dma_unmap() currently check the cp_partial flag and adjust the page_count so that pagebuf entries for the RNDIS portion of the message are skipped when it has already been copied into a send buffer. But this adjustment has already been made by code in netvsc_send(). The duplicate adjustment causes some pagebuf entries to not be mapped. In a normal VM, this doesn't break anything because the mapping doesn’t change the PFN. But in a Confidential VM, dma_map_single() does bounce buffering and provides a different PFN. Failing to do the mapping causes the wrong PFN to be passed to Hyper-V, and various errors ensue. Fix this by removing the duplicate adjustment in netvsc_dma_map() and netvsc_dma_unmap().
