wifi: move from strlcpy with unused retval to strscpy

2022-09-02T08:47:22Z

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.

intersil: Use struct_group() for memcpy() region

2021-11-29T10:45:17Z

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Use struct_group() in struct hfa384x_tx_frame around members frame_control, duration_id, addr1, addr2, addr3, and seq_ctrl, so they can be referenced together. This will allow memcpy() and sizeof() to more easily reason about sizes, improve readability, and avoid future warnings about writing beyond the end of frame_control. "pahole" shows no size nor member offset changes to struct hfa384x_tx_frame. "objdump -d" shows no object code changes.

hostap: use eth_hw_addr_set()

2021-10-20T09:39:46Z

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.

hostap: use ndo_siocdevprivate

2021-07-27T19:11:43Z

hostap has a combination of iwpriv ioctls that do not work at all, and two SIOCDEVPRIVATE commands that work natively but lack a compat conversion handler. For the moment, move them over to the new ndo_siocdevprivate interface and return an error for compat mode. Cc: Jouni Malinen Cc: Kalle Valo Signed-off-by: Arnd Bergmann Signed-off-by: David S.

proc: mandate ->proc_lseek in "struct proc_ops"

2021-05-07T02:24:11Z

Now that proc_ops are separate from file_operations and other operations it easy to check all instances to have ->proc_lseek hook and remove check in main code. Note: nonseekable_open() files naturally don't require ->proc_lseek. Garbage collect pde_lseek() function.

module: remove never implemented MODULE_SUPPORTED_DEVICE

2021-03-17T20:16:18Z

MODULE_SUPPORTED_DEVICE was added in pre-git era and never was implemented. We can safely remove it, because the kernel has grown to have many more reliable mechanisms to determine if device is supported or not. Signed-off-by: Leon Romanovsky Signed-off-by: Linus Torvalds

hostap: Remove in_atomic() check.

2020-11-07T15:52:22Z

hostap_get_wireless_stats() is the iw_handler_if::get_wireless_stats() callback of this driver. This callback was not allowed to sleep until commit a160ee69c6a46 ("wext: let get_wireless_stats() sleep") in v2.6.32. Remove the therefore pointless in_atomic() check.
