rtnetlink: remove redundant checks for nlattr IFLA_BRIDGE_MODE

2023-08-08T22:10:37+00:00

The commit d73ef2d69c0d ("rtnetlink: let rtnl_bridge_setlink checks
IFLA_BRIDGE_MODE length") added the nla_len check in rtnl_bridge_setlink,
which is the only caller for ndo_bridge_setlink handlers defined in
low-level driver codes. Hence, this patch cleanups the redundant checks in
each ndo_bridge_setlink handler function.

in be_lancer_xmit_workarounds(), it should go to label 'tx_drop'
if an unexpected value is returned by pskb_trim().

be2net: Extend xmit workaround to BE3 chip

2023-06-20T19:18:01+00:00

We have seen a bug where the NIC incorrectly changes the length in the
IP header of a padded packet to include the padding bytes. The driver
already has a workaround for this so do the workaround for this NIC too.
This resolves the issue.

The NIC in question identifies itself as follows:

[    8.828494] be2net 0000:02:00.0: FW version is 10.7.110.31
[    8.834759] be2net 0000:02:00.0: Emulex OneConnect(be3): PF FLEX10 port 1

02:00.0 Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 01)

net: introduce and use skb_frag_fill_page_desc()

2023-05-13T18:47:56+00:00

Most users use __skb_frag_set_page()/skb_frag_off_set()/
skb_frag_size_set() to fill the page desc for a skb frag.

Introduce skb_frag_fill_page_desc() to do that.

net/bpf/test_run.c does not call skb_frag_off_set() to
set the offset, "copy_from_user(page_address(page), ...)"
and 'shinfo' being part of the 'data' kzalloced in
bpf_test_init() suggest that it is assuming offset to be
initialized as zero, so call skb_frag_fill_page_desc()
with offset being zero for this case.

Also, skb_frag_set_page() is not used anymore, so remove
it.

net: vlan: introduce skb_vlan_eth_hdr()

2023-04-23T13:16:44+00:00

Similar to skb_eth_hdr() introduced in commit 96cc4b69581d ("macvlan: do
not assume mac_header is set in macvlan_broadcast()"), let's introduce a
skb_vlan_eth_hdr() helper which can be used in TX-only code paths to get
to the VLAN header based on skb->data rather than based on the
skb_mac_header(skb).

We also consolidate the drivers that dereference skb->data to go through
this helper.

be2net: Drop redundant pci_enable_pcie_error_reporting()

2023-03-09T07:34:38+00:00

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration,  so the
driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14+00:00

We tell driver developers to always pass NAPI_POLL_WEIGHT
as the weight to netif_napi_add(). This may be confusing
to newcomers, drop the weight argument, those who really
need to tweak the weight can use netif_napi_add_weight().
