Therefore, when using\nor_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE),\nthe code is incorrectly searching for a bit in a 32-bit\nvariable that is expected to be 64 bits in size,\nleading to incorrect bit finding.\n\nSolution: Ensure that the size of the bits variable is correctly\nadjusted for each architecture.\n\n Call Trace:\n  ? show_regs+0x54/0x58\n  ? __warn+0x6b/0xd4\n  ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211]\n  ? report_bug+0x113/0x150\n  ? exc_overflow+0x30/0x30\n  ? handle_bug+0x27/0x44\n  ? exc_invalid_op+0x18/0x50\n  ? handle_exception+0xf6/0xf6\n  ? exc_overflow+0x30/0x30\n  ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211]\n  ? exc_overflow+0x30/0x30\n  ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211]\n  ? ieee80211_mesh_work+0xff/0x260 [mac80211]\n  ? cfg80211_wiphy_work+0x72/0x98 [cfg80211]\n  ? process_one_work+0xf1/0x1fc\n  ? worker_thread+0x2c0/0x3b4\n  ? kthread+0xc7/0xf0\n  ? mod_delayed_work_on+0x4c/0x4c\n  ? kthread_complete_and_exit+0x14/0x14\n  ? ret_from_fork+0x24/0x38\n  ? kthread_complete_and_exit+0x14/0x14\n  ? ret_from_fork_asm+0xf/0x14\n  ? entry_INT80_32+0xf0/0xf0\n\n[restore no-op path for no changes]\n\ud83d\udccf Published: 2025-01-15T13:05:50.701Z\n\ud83d\udccf Modified: 2025-01-15T13:05:50.701Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/86772872f9f5097cd03d0e1c6813238bd38c250b\n2. https://git.kernel.org/stable/c/36b739637d7042843f9df57212ecee6ed6e0d4b2\n3. https://git.kernel.org/stable/c/49dba1ded8dd5a6a12748631403240b2ab245c34", "creation_timestamp": "2025-01-15T14:21:29.000000Z"}
