net: usb: catc: enable basic endpoint checking

2026-02-26T22:59:39Z

[ Upstream commit 9e7021d2aeae57c323a6f722ed7915686cdcc123 ] catc_probe() fills three URBs with hardcoded endpoint pipes without verifying the endpoint descriptors: - usb_sndbulkpipe(usbdev, 1) and usb_rcvbulkpipe(usbdev, 1) for TX/RX - usb_rcvintpipe(usbdev, 2) for interrupt status A malformed USB device can present these endpoints with transfer types that differ from what the driver assumes. Add a catc_usb_ep enum for endpoint numbers, replacing magic constants throughout. Add usb_check_bulk_endpoints() and usb_check_int_endpoints() calls after usb_set_interface() to verify endpoint types before use, rejecting devices with mismatched descriptors at probe time. Similar to - commit 90b7f2961798 ("net: usb: rtl8150: enable basic endpoint checking") which fixed the issue in rtl8150.

treewide, timers: Rename from_timer() to timer_container_of()

2025-06-08T07:07:37Z

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

net: move from strlcpy with unused retval to strscpy

2022-08-31T21:11:07Z

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.

usbb: catc: use correct API for MAC addresses

2021-10-25T14:34:02Z

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. In the case of catc we need a new temporary buffer to conform to the rules for DMA coherency. That in turn necessitates a reworking of error handling in probe().

ethernet: constify references to netdev->dev_addr in drivers

2021-10-14T16:22:11Z

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.
