Since implementing VLAN filtering in commit 05cc5a39 ("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while the interface is down: # ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10 RTNETLINK answers: Bad address and in dmesg (with bnx2x.debug=0x20): bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN configuration the interface is down Other drivers have no problem with this. Fix this peculiar behavior in the following way: - Accept requests to add/kill VID regardless of the device state. Maintain the requested list of VIDs in the bp->vlan_reg list. - If the device is up, try to configure the VID list into the hardware. If we run out of VLAN credits or encounter a failure configuring an entry, fall back to accepting all VLANs. If we successfully configure all entries from the list, turn the fallback off. - Use the same code for reconfiguring VLANs during NIC load. Signed-off-by:

John Crispin says: ==================== net-next: mediatek: improve phy support The current driver did not handle the RGMII delay modes and asymmetric flow control properly. The mii_bus is not freed properly. Also add support for fixed-phy allowing the driver to work on SoCs that have an internal gigabit switch. ==================== Signed-off-by:

If an external Gigabit PHY is connected to either of the MACs we need to be able to tell the PHY to use a delay. Not doing so will result in heavy packet loss and/or data corruption when using PHYs such as the IC+ IP1001. We tell the PHY which MII delay mode to use via the devictree. The ethernet driver needs to be adapted to handle all 3 rgmii-*id modes in the same way as normal rgmii when setting up the MAC. Reviewed-by:

The MT7623 SoC has a builtin gigabit switch. If we want to use it, GMAC1 needs to be configured using a fixed link speed and flow control settings. The easiest way to do this is to used the fixed-phy driver, allowing us to reuse the existing mdio polling code to setup the MAC. Reviewed-by:

The rx-usecs shouldn't be changed while interface down/up. Currently, for instance, if it's set to 100us, after interface down/up it's 500us. It's a hidden bug that can lead to lavish interrupt pacing time increasing while "down/up" up to max value. Steps to reproduce: - set rx-usecs to be 100us - down/up interface - read new unexpected rx-usecs Signed-off-by:

A regression was introduced in commit 9c349892 ("brcmfmac: revise handling events in receive path") which moves eth_type_trans() call to brcmf_rx_frame(). Msgbuf layer doesn't use brcmf_rx_frame() but invokes brcmf_netif_rx() directly. In such case the Ethernet header was not stripped out resulting in null pointer dereference in the networking stack.

Paul Moore tracked a regression caused by a recent commit, which mistakenly assumed that sk_filter() could be avoided if socket had no current BPF filter. The intent was to avoid udp_lib_checksum_complete() overhead. But sk_filter() also checks skb_pfmemalloc() and security_sock_rcv_skb(), so better call it.

stmmac_mdio_reset() has been updated to use msleep rather udelay (as some PHY requires a one second delay there). It called from stmmac_resume() within the spin_lock_irqsave block atomic context triggering 'scheduling while atomic'. The stmmac_priv lock usage is not fully documented, but it seems to protect the access to the MAC registers / DMA structures rather than the MDIO bus or the PHY (which have separate locking), so we can push the spin_lock after the stmmac_mdio_reset call.

gcc warns about qed_fill_link possibly accessing uninitialized data: drivers/net/ethernet/qlogic/qed/qed_main.c: In function 'qed_fill_link': drivers/net/ethernet/qlogic/qed/qed_main.c:1170:35: error: 'link_caps' may be used uninitialized in this function [-Werror=maybe-uninitialized] While this warning is only about the specific case of CONFIG_QED_SRIOV being disabled but the function getting called for a VF (which should never happen), another possibility is that qed_mcp_get_*() fails without returning data. This rearranges the code so we bail out in either of the two cases and print a warning instead of accessing the uninitialized data. The qed_link_output structure remains untouched in this case, but all callers first call memset() on it, so at least we are not leaking stack data then. As discussed, we also use a compile-time check to ensure we never use any of the VF code if CONFIG_QED_SRIOV is disabled, and the PCI device table is updated to no longer bind to virtual functions in that configuration.

The Kconfig options I added to work around broken compilation ended up screwing up things more, as I used the wrong symbol to control compilation of the file, resulting in IPv6 fou support to never be built into the kernel. Changing CONFIG_NET_FOU_IPV6_TUNNELS to CONFIG_IPV6_FOU fixes that problem, I had renamed the symbol in one location but not the other, and as the file is never being used by other kernel code, this did not lead to a build failure that I would have caught. After that fix, another issue with the same patch becomes obvious, as we 'select INET6_TUNNEL', which is related to IPV6_TUNNEL, but not the same, and this can still cause the original build failure when IPV6_TUNNEL is not built-in but IPV6_FOU is. The fix is equally trivial, we just need to select the right symbol. I have successfully build 350 randconfig kernels with this patch and verified that the driver is now being built. Signed-off-by:

Now we cannot distinguish that one sk is a udp or sctp style when we use ss to dump sctp_info. it's necessary to dump it as well. For sctp_diag, ss support is not officially available, thus there are no official users of this yet, so we can add this field in the middle of sctp_info without breaking user API. v1->v2: - move 'sctpi_s_type' field to the end of struct sctp_info, so that it won't cause incompatibility with applications already built. - add __reserved3 in sctp_info to make sure sctp_info is 8-byte alignment.

The MAC address of the physical interface is only copied to the VLAN when it is first created, resulting in an inconsistency after MAC address changes of only newly created VLANs having an up-to-date MAC. The VLANs should continue inheriting the MAC address of the physical interface until the VLAN MAC address is explicitly set to any value. This allows IPv6 EUI64 addresses for the VLAN to reflect any changes to the MAC of the physical interface and thus for DAD to behave as expected. Signed-off-by:

The iadev->rx_open[] array holds "iadev->num_vc" pointers (this code assumes that pointers are 32 bits). So the > here should be >= or else we could end up reading a garbage pointer from one element beyond the end of the array. Signed-off-by:

This bug was there when the driver was first added in back in year 2000. It causes a Smatch warning: drivers/atm/firestream.c:849 process_incoming() error: buffer overflow 'res_strings' 60 <= 63 There are supposed to be 64 entries in this array and the missing strings are clearly in the 30 40 range. I added them as reserved 37 to reserved 40. It's possible that strings are really supposed to be added in the middle instead of at the end, but this approach is safe, in that it fixes the bug and doesn't break anything that wasn't already broken.

When create a new vxlan link, example: ip link add vtap mtu 1440 type vxlan vni 1 dev eth0 The argument "mtu" has no effect, because it is not set to conf->mtu. The default value is used in vxlan_dev_configure function. This problem was introduced by commit 0dfbdf41 (vxlan: Factor out device configuration).

hrtimer_init_on_stack() needs a matching call to destroy_hrtimer_on_stack(), so both need to be exported. Signed-off-by:
