This is a bug as the function that it is attaching to is not necessarily the one that the user wants to attach to. Instead of blindly picking a function to attach to what is ambiguous, error with EADDRNOTAVAIL to let the user know that this function is not unique, and that the user must use another unique function with an address offset to get to the function they want to attach to.

[PATCH 1/3] cpufreq: fix broken buffer overflow detection in trans_stats

by Christian Marangi

Commit 3c0897c180c6 ("cpufreq: Use scnprintf() for avoiding potential buffer overflow") switched from snprintf to the more secure scnprintf but never updated the exit condition for PAGE_SIZE. As the commit say and as scnprintf document, what scnprintf returns what is actually written not counting the '\0' end char. This results in the case of len exceeding the size, len set to PAGE_SIZE - 1, as it can be written at max PAGESIZE - 1 (as '\0' is not counted) Because of len is never set to PAGE_SIZE, the function never break early, never print the warning and never return -EFBIG. Fix this by fixing the condition to PAGE_SIZE -1 to correctly trigger the error condition.

[REGRESSION] Backport? RIP: 0010:throtl_trim_slice+0xc6/0x320 caused kernel panic

by Christian Theune

Hi, I hope i’m not jumping the gun, but I guess I’d be interested in a backport to said issue … ;) We’re running on 6.1.55/57 and this has started breaking for us after we updated from 6.1.51. The issue seems to be well-described and already fixed in https://lkml.kernel.org/linux-block/e1d7c106-ea6f-922f-971f-691e7e0faf9d@hu… but I can’t post to that thread easily and it seems backporting isn’t on the radar as of now.

[PATCH v1 net] net: ethtool: Fix documentation of ethtool_sprintf()

This function takes a pointer to a pointer, unlike sprintf() which is passed a plain pointer. Fix up the documentation to make this clear.
