net: pch_gbe: Remove obsolete 32-bit DMA mask fallback

2026-09-08T23:46:27+00:00

The DMA API guarantees support for masks of 32 bits or wider and explicitly identifies retrying a 32-bit mask after a 64-bit request as incorrect: https://docs.kernel.org/core-api/dma-api-howto.html#dma-addressing-capabilities Remove the obsolete fallback while retaining the error check so that a genuine DMA setup failure is still reported and aborts initialization.

net: pch_gbe: handle TX skb allocation failure

2026-06-19T01:00:35+00:00

pch_gbe_alloc_tx_buffers() allocates an skb for each TX descriptor and then passes the returned pointer to skb_reserve(). If netdev_alloc_skb() fails, skb_reserve() dereferences NULL. Make pch_gbe_alloc_tx_buffers() return an error when an skb allocation fails. On failure, let pch_gbe_alloc_tx_buffers() clean the partially allocated TX ring before returning the error. While bringing the device up, release the RX buffer pool through a shared cleanup helper before unwinding the IRQ setup.

net: pch_gbe: convert to use ndo_hwtstamp callbacks

2025-11-05T01:43:52+00:00

The driver implemented SIOCSHWTSTAMP ioctl command only, but it stores configuration in the private data, so it is possible to report it back to users. Implement both ndo_hwtstamp_set and ndo_hwtstamp_get callbacks. To properly report RX filter type, store it in hwts_rx_en instead of using this field as a simple flag. The logic didn't change because receive path used this field as boolean flag.

net: annotate writes on dev->mtu from ndo_change_mtu()

2024-05-07T23:19:14+00:00

Simon reported that ndo_change_mtu() methods were never updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted in commit 501a90c94510 ("inet: protect against too small mtu values.") We read dev->mtu without holding RTNL in many places, with READ_ONCE() annotations. It is time to take care of ndo_change_mtu() methods to use corresponding WRITE_ONCE() Signed-off-by: Eric Dumazet Reported-by: Simon Horman Closes: https://lore.kernel.org/netdev/20240505144608.GB67882@kernel.org/ Reviewed-by: Jacob Keller Reviewed-by: Sabrina Dubroca Reviewed-by: Simon Horman Acked-by: Shannon Nelson Link: https://lore.kernel.org/r/20240506102812.3025432-1-edumazet@google.com Signed-off-by: Jakub Kicinski

net: pch_gbe: Allow build on MIPS_GENERIC kernel

2023-06-09T02:18:32+00:00

MIPS Boston board, which is using MIPS_GENERIC kernel is using EG20T PCH and thus need this driver. Dependency of PCH_GBE, PTP_1588_CLOCK_PCH is also fixed for MIPS_GENERIC. Note that CONFIG_PCH_GBE is selected in arch/mips/configs/generic/ board-boston.config for a while, some how it's never wired up in Kconfig.

net: pch_gbe: fix pci device refcount leak while module exiting

2022-11-19T03:40:14+00:00

As comment of pci_get_domain_bus_and_slot() says, it returns a pci device with refcount increment, when finish using it, the caller must decrement the reference count by calling pci_dev_put(). In pch_gbe_probe(), pci_get_domain_bus_and_slot() is called, so in error path in probe() and remove() function, pci_dev_put() should be called to avoid refcount leak. Compile tested only.

net: pch_gbe: fix potential memleak in pch_gbe_tx_queue()

2022-11-18T13:00:36+00:00

In pch_gbe_xmit_frame(), NETDEV_TX_OK will be returned whether pch_gbe_tx_queue() sends data successfully or not, so pch_gbe_tx_queue() needs to free skb before returning. But pch_gbe_tx_queue() returns without freeing skb in case of dma_map_single() fails. Add dev_kfree_skb_any() to fix it.
