2022-08-31net: move from strlcpy with unused retval to strscpyWolfram Sang1-1/+1
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 Kicinski1-1/+1
Drivers should call the TSO setting helper, GSO is controllable by user space. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-04-06net: usb: aqc111: Fix out-of-bounds accesses in RX fixupMarcin Kozlowski1-2/+7
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 Kicinski1-1/+1
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 Russkikh1-4/+2
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 Neukum1-6/+17
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.

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.
