2020-09-07sfc: simplify DMA mask settingEdward Cree1-11/+1
Christoph says[1] that dma_set_mask_and_coherent() is smart enough to truncate the mask itself if it's too long. So we can get rid of our "lop off one bit and retry" loop in efx_init_io().

If the reported PHY capabilities do not include a given FEC mode, don't attempt to select that FEC mode anyway. If the user tries to set a mode through ethtool that is not supported, return an error.

2020-09-07sfc: remove phy_op indirectionEdward Cree9-712/+601
Originally there were several implementations of PHY operations for the several different PHYs used on Falcon boards. But Falcon is now in a separate driver, and all sfc NICs since then have had MCDI-managed PHYs. Thus, there is no need to indirect through function pointers in efx->phy_op; we can simply call the efx_mcdi_phy_* functions directly. This also hooks up these functions for EF100, which was previously using the dummy_phy_ops. Signed-off-by: Edward Cree <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
2020-09-07sfc: don't double-down() filters in ef100_reset()Edward Cree1-12/+0
dev_close(), by way of ef100_net_stop(), already brings down the filter table, so there's no need to do it again (which just causes lots of WARN_ONs). Similarly, don't bring it up ourselves, as dev_open() -> ef100_net_open() will do it, and will fail if it's already been brought up.

2020-09-07bnxt_en: Fix NULL ptr dereference crash in bnxt_fw_reset_task()Vasundhara Volam1-3/+4
bnxt_fw_reset_task() which runs from a workqueue can race with bnxt_remove_one(). For example, if firmware reset and VF FLR are happening at about the same time. bnxt_remove_one() already cancels the workqueue and waits for it to finish, but we need to do this earlier before the devlink reporters are destroyed. This will guarantee that the devlink reporters will always be valid when bnxt_fw_reset_task() is still running. Fixes: b148bb238c02 ("bnxt_en: Fix possible crash in bnxt_fw_reset_task().")

2020-09-07bnxt_en: Avoid sending firmware messages when AER error is detected.Vasundhara Volam2-3/+7
When the driver goes through PCIe AER reset in error state, all firmware messages will timeout because the PCIe bus is no longer accessible. This can lead to AER reset taking many minutes to complete as each firmware command takes time to timeout. Define a new macro BNXT_NO_FW_ACCESS() to skip these firmware messages when either firmware is in fatal error state or when pci_channel_offline() is true. It now takes a more reasonable 20 to 30 seconds to complete AER recovery. Fixes: b4fff2079d10 ("bnxt_en: Do not send firmware messages if firmware is in error state.")

2020-09-06enic: switch from 'pci_' to 'dma_' APIChristophe JAILLET2-70/+72
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'vnic_dev_classifier()', 'vnic_dev_fw_info()', 'vnic_dev_notify_set()' and 'vnic_dev_stats_dump()' (vnic_dev.c) GFP_ATOMIC must be used because its callers take a spinlock before calling these functions. When memory is allocated in '__enic_set_rsskey()' and 'enic_set_rsscpu()' GFP_ATOMIC must be used because they can be called with a spinlock. The call chain is: enic_reset <-- takes 'enic->enic_api_lock' --> enic_set_rss_nic_cfg --> enic_set_rsskey --> __enic_set_rsskey <-- uses dma_alloc_coherent --> enic_set_rsscpu <-- uses dma_alloc_coherent When memory is allocated in 'vnic_dev_init_prov2()' GFP_ATOMIC must be used because a spinlock is hidden in the ENIC_DEVCMD_PROXY_BY_INDEX macro, when this function is called in 'enic_set_port_profile()'. When memory is allocated in 'vnic_dev_alloc_desc_ring()' GFP_KERNEL can be used because it is only called from 5 functions ('vnic_dev_init_devcmd2()', 'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()' and 'enic_wq_devcmd2_alloc()'. 'vnic_dev_init_devcmd2()': already uses GFP_KERNEL and no lock is taken in the between. 'enic_wq_devcmd2_alloc()': is called from ' vnic_dev_init_devcmd2()' which already uses GFP_KERNEL and no lock is taken in the between. 'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()': are called from 'enic_alloc_vnic_resources()' 'enic_alloc_vnic_resources()' has only 2 call chains: 1) enic_probe --> enic_dev_init --> enic_alloc_vnic_resources 'enic_probe()' is a probe function and no lock is taken in the between 2) enic_set_ringparam --> enic_alloc_vnic_resources 'enic_set_ringparam()' is a .set_ringparam function (see struct ethtool_ops). It seems to only take a mutex and no spinlock. So all paths are safe to use GFP_KERNEL. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>

When memory is allocated in 'epic_init_one()', GFP_KERNEL can be used because it is a probe function and no lock is acquired. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <[email protected]> Signed-off-by: David S.

We disable clocks shortly after probing the device to save as much power as possible in case the interface is never used.

2020-09-03chelsio/chtls: CHELSIO_INLINE_CRYPTO should depend on CHELSIO_T4Geert Uytterhoeven1-2/+1
While CHELSIO_INLINE_CRYPTO is a guard symbol, and just enabling it does not cause any additional code to be compiled in, all configuration options protected by it depend on CONFIG_CHELSIO_T4. Hence it doesn't make much sense to bother the user with the guard symbol question when CONFIG_CHELSIO_T4 is disabled. Fix this by moving the dependency from the individual config options to the guard symbol.

2020-09-03tg3: Fix soft lockup when tg3_reset_task() fails.Michael Chan1-4/+13
If tg3_reset_task() fails, the device state is left in an inconsistent state with IFF_RUNNING still set but NAPI state not enabled. A subsequent operation, such as ifdown or AER error can cause it to soft lock up when it tries to disable NAPI state. Fix it by bringing down the device to !IFF_RUNNING state when tg3_reset_task() fails. tg3_reset_task() running from workqueue will now call tg3_close() when the reset fails. We need to modify tg3_reset_task_cancel() slightly to avoid tg3_close() calling cancel_work_sync() to cancel tg3_reset_task(). Otherwise cancel_work_sync() will wait forever for tg3_reset_task() to finish.
