[REGRESSION] 6.14.3 panic - kernel NULL pointer dereference in htb_dequeue

by Alan J. Wylie

#regzbot introduced: 6.14.2..6.14.3 Since 6.14.3 I have been seeing random panics, all in htb_dequeue. 6.14.2 was fine. One only happened 8 hours after the reboot, so bisecting would be prolonged, since I have no idea what is triggering the crash. I've captured three panics with netconsole. All are very similar. I've also included the script I use to initialise tc. As well as when the ppp over ethernet interface comes up, I also run this every 5 minutes as a cron job since my ADSL line can fluctuate between 22 and 30 Mb/s. However, from the timings of the last few lines in /var/log/messages before the crash, it doesn't seem that this is directly related. Finally, I've decoded the first panic. I'm more than happy to help with debugging, if necessary. The system is running up-to-date Gentoo.

[PATCH] f2fs: fix to do sanity check on sit_bitmap_size

by Chao Yu

w/ below testcase, resize will generate a corrupted image which contains inconsistent metadata, so when mounting such image, it will trigger kernel panic: touch img truncate -s $((512*1024*1024*1024)) img mkfs.f2fs -f img $((256*1024*1024)) resize.f2fs -s -i img -t $((1024*1024*1024)) mount img /mnt/f2fs ------------[ cut here ]------------ kernel BUG at fs/f2fs/segment.h:863!

[PATCH net V3] amd-xgbe: Fix to ensure dependent features are toggled with RX checksum offload

by Vishal Badole

According to the XGMAC specification, enabling features such as Layer 3 and Layer 4 Packet Filtering, Split Header and Virtualized Network support automatically selects the IPC Full Checksum Offload Engine on the receive side. When RX checksum offload is disabled, these dependent features must also be disabled to prevent abnormal behavior caused by mismatched feature dependencies. Ensure that toggling RX checksum offload (disabling or enabling) properly disables or enables all dependent features, maintaining consistent and expected behavior in the network device. v2->v3: ------- - Removed RSS feature toggling as checksum offloading functions correctly without it v1->v2: ------- - Combine 2 patches into a single patch - Update the "Fix: tag" - Add necessary changes to support earlier versions of the hardware as well Cc: stable(a)vger.kernel.org Fixes: 1a510ccf5869 ("amd-xgbe: Add support for VXLAN offload capabilities") Signed-off-by: Vishal Badole <Vishal.Badole(a)amd.com> --- drivers/net/ethernet/amd/xgbe/xgbe-desc.c | 9 +++++++-- drivers/net/ethernet/amd/xgbe/xgbe-dev.c | 24 +++++++++++++++++++++-- drivers/net/ethernet/amd/xgbe/xgbe-drv.c | 11 +++++++++-- drivers/net/ethernet/amd/xgbe/xgbe.h | 4 ++++ 4 files changed, 42 insertions(+), 6 deletions(-) diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-desc.c b/drivers/net/ethernet/amd/xgbe/xgbe-desc.c index 230726d7b74f..d41b58fad37b 100644 --- a/drivers/net/ethernet/amd/xgbe/xgbe-desc.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-desc.c @@ -373,8 +373,13 @@ static int xgbe_map_rx_buffer(struct xgbe_prv_data *pdata, } /* Set up the header page info */ - xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, - XGBE_SKB_ALLOC_SIZE); + if (pdata->netdev->features & NETIF_F_RXCSUM) { + xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, + XGBE_SKB_ALLOC_SIZE); + } else { + xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, + pdata->rx_buf_size); + } /* Set up the buffer page info */ xgbe_set_buffer_data(&rdata->rx.buf, &ring->rx_buf_pa, diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-dev.c b/drivers/net/ethernet/amd/xgbe/xgbe-dev.c index 7a923b6e83df..d0a35aab7355 100644 --- a/drivers/net/ethernet/amd/xgbe/xgbe-dev.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-dev.c @@ -321,6 +321,18 @@ static void xgbe_config_sph_mode(struct xgbe_prv_data *pdata) XGMAC_IOWRITE_BITS(pdata, MAC_RCR, HDSMS, XGBE_SPH_HDSMS_SIZE); } +static void xgbe_disable_sph_mode(struct xgbe_prv_data *pdata) +{ + unsigned int i; + + for (i = 0; i < pdata->channel_count; i++) { + if (!pdata->channel[i]->rx_ring) + break; + + XGMAC_DMA_IOWRITE_BITS(pdata->channel[i], DMA_CH_CR, SPH, 0); + } +} + static int xgbe_write_rss_reg(struct xgbe_prv_data *pdata, unsigned int type, unsigned int index, unsigned int val) { @@ -3750,8 +3762,12 @@ static int xgbe_init(struct xgbe_prv_data *pdata) xgbe_config_tx_coalesce(pdata); xgbe_config_rx_buffer_size(pdata); xgbe_config_tso_mode(pdata); - xgbe_config_sph_mode(pdata); - xgbe_config_rss(pdata); + + if (pdata->netdev->features & NETIF_F_RXCSUM) { + xgbe_config_sph_mode(pdata); + xgbe_config_rss(pdata); + } + desc_if->wrapper_tx_desc_init(pdata); desc_if->wrapper_rx_desc_init(pdata); xgbe_enable_dma_interrupts(pdata); @@ -3910,5 +3926,9 @@ void xgbe_init_function_ptrs_dev(struct xgbe_hw_if *hw_if) hw_if->disable_vxlan = xgbe_disable_vxlan; hw_if->set_vxlan_id = xgbe_set_vxlan_id; + /* For Split Header*/ + hw_if->enable_sph = xgbe_config_sph_mode; + hw_if->disable_sph = xgbe_disable_sph_mode; + DBGPR("<--xgbe_init_function_ptrs\n"); } diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-drv.c b/drivers/net/ethernet/amd/xgbe/xgbe-drv.c index f249f89fec38..51b4adb8a404 100755 --- a/drivers/net/ethernet/amd/xgbe/xgbe-drv.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-drv.c @@ -2290,10 +2290,17 @@ static int xgbe_set_features(struct net_device *netdev, if (ret) return ret; - if ((features & NETIF_F_RXCSUM) && !rxcsum) + if ((features & NETIF_F_RXCSUM) && !rxcsum) { + hw_if->enable_sph(pdata); + hw_if->enable_vxlan(pdata); hw_if->enable_rx_csum(pdata); - else if (!(features & NETIF_F_RXCSUM) && rxcsum) + schedule_work(&pdata->restart_work); + } else if (!(features & NETIF_F_RXCSUM) && rxcsum) { + hw_if->disable_sph(pdata); + hw_if->disable_vxlan(pdata); hw_if->disable_rx_csum(pdata); + schedule_work(&pdata->restart_work); + } if ((features & NETIF_F_HW_VLAN_CTAG_RX) && !rxvlan) hw_if->enable_rx_vlan_stripping(pdata); diff --git a/drivers/net/ethernet/amd/xgbe/xgbe.h b/drivers/net/ethernet/amd/xgbe/xgbe.h index db73c8f8b139..92b61a318f66 100755 --- a/drivers/net/ethernet/amd/xgbe/xgbe.h +++ b/drivers/net/ethernet/amd/xgbe/xgbe.h @@ -902,6 +902,10 @@ struct xgbe_hw_if { void (*enable_vxlan)(struct xgbe_prv_data *); void (*disable_vxlan)(struct xgbe_prv_data *); void (*set_vxlan_id)(struct xgbe_prv_data *); + + /* For Split Header */ + void (*enable_sph)(struct xgbe_prv_data *pdata); + void (*disable_sph)(struct xgbe_prv_data *pdata); }; /* This structure represents implementation specific routines for an -- 2.34.1
