2022-08-31net: move from strlcpy with unused retval to strscpyWolfram Sang
Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

2022-05-06net: make drivers set the TSO limit not the GSO limitJakub Kicinski

2022-04-06net: usb: aqc111: Fix out-of-bounds accesses in RX fixupMarcin Kozlowski
aqc111_rx_fixup() contains several out-of-bounds accesses that can be triggered by a malicious (or defective) USB device, in particular: - The metadata array (desc_offset..desc_offset+2*pkt_count) can be out of bounds, causing OOB reads and (on big-endian systems) OOB endianness flips. - A packet can overlap the metadata array, causing a later OOB endianness flip to corrupt data used by a cloned SKB that has already been handed off into the network stack. - A packet SKB can be constructed whose tail is far beyond its end, causing out-of-bounds heap data to be considered part of the SKB's data. Found doing variant analysis. Tested it with another driver (ax88179_178a), since I don't have a aqc111 device to test it, but the code looks very similar.

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski
This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. 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 got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

2019-05-16aqc111: cleanup mtu related logicIgor Russkikh
Original fix b8b277525e9d was done under impression that invalid data could be written for mtu configuration higher that 16334. But the high limit will anyway be rejected my max_mtu check in caller. Thus, make the code cleaner and allow it doing the configuration without checking for maximum mtu value.

2019-05-09aqc111: fix writing to the phy on BEOliver Neukum
When writing to the phy on BE architectures an internal data structure was directly given, leading to it being byte swapped in the wrong way for the CPU in 50% of all cases.

2019-05-09aqc111: fix endianness issue in aqc111_change_mtuOliver Neukum
If the MTU is large enough, the first write to the device is just repeated. On BE architectures, however, the first word of the command will be swapped a second time and garbage will be written.
