2021-10-28net: virtio: use eth_hw_addr_set()Jakub Kicinski1-3/+7
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it go through appropriate helpers. Even though the current code uses dev->addr_len the we can switch to eth_hw_addr_set() instead of dev_addr_set(). The netdev is always allocated by alloc_etherdev_mq() and there are at least two places which assume Ethernet address: - the line below calling eth_hw_addr_random() - virtnet_set_mac_address() -> eth_commit_mac_addr_change() Acked-by: Michael S.

2021-10-28octeontx2-af: cn10k: debugfs for dumping LMTST map tableHarman Kalra1-0/+94
CN10k SoCs use atomic stores of up to 128 bytes to submit packets/instructions into co-processor cores. The enqueueing is performed using Large Memory Transaction Store (LMTST) operations. They allow for lockless enqueue operations - i.e., two different CPU cores can submit instructions to the same queue without needing to lock the queue or synchronize their accesses. This patch implements a new debugfs entry for dumping LMTST map table present on CN10K, as this might be very useful to debug any issue in case of shared LMTST region among multiple pci functions.

2021-10-28octeontx2-af: Display all enabled PF VF rsrc_alloc entries.Rakesh Babu1-32/+106
Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size. Fixes: f7884097141b ("octeontx2-af: Formatting debugfs entry rsrc_alloc.")

2021-10-28net: ipconfig: Release the rtnl_lock while waiting for carrierMaxime Chevallier1-2/+10
While waiting for a carrier to come on one of the netdevices, some devices will require to take the rtnl lock at some point to fully initialize all parts of the link. That's the case for SFP, where the rtnl is taken when a module gets detected. This prevents mounting an NFS rootfs over an SFP link. This means that while ipconfig waits for carriers to be detected, no SFP modules can be detected in the meantime, it's only detected after ipconfig times out. This commit releases the rtnl_lock while waiting for the carrier to come up, and re-takes it to check the for the init device and carrier status.

2021-10-28ipv6: enable net.ipv6.route.max_size sysctl in network namespaceAlexander Kuznetsov1-12/+12
We want to increase route cache size in network namespace created with user namespace. Currently ipv6 route settings are disabled for non-initial network namespaces. We can allow this sysctl and it will be safe since commit <6126891c6d4f> because route cache account to kmem, that is why users from user namespace can not DOS system.

2021-10-28mpt fusion: use dev_addr_set()Jakub Kicinski1-1/+1
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it go through appropriate helpers. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Martin K.

2021-10-28firewire: don't write directly to netdev->dev_addrJakub Kicinski1-7/+7
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it go through appropriate helpers. Prepare fwnet_hwaddr on the stack and use dev_addr_set() to copy it to netdev->dev_addr. We no longer need to worry about alignment. union fwnet_hwaddr does not have any padding and we set all fields so we don't need to zero it upfront.

Eric Dumazet says: ==================== tcp: tx side cleanups We no longer need to set skb->reserved_tailroom because TCP sendmsg() do not put payload in skb->head anymore. Also do some cleanups around skb->ip_summed/csum, and CP_SKB_CB(skb)->sacked for fresh skbs. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
