From cf9610f9116d55c5a66ef9f1faecacabd93a9322 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 24 Aug 2026 08:46:03 -0700 Subject: Merge tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Core changes: - Use the non-blocking mux_state_try_select() in the generic MUX pin control back-end - Free pin maps on pinctrl_generic_to_map() failure in the core helpers New hardware pin control: - Qualcomm Maili TLMM SoC, PMG1110 PMIC, and Eliza LPASS LPI TLMM SoC (this is for the low power audio, LPASS = Low Power Audio SubSystem portions) - Upboard support on top of the Intel pin controller - Apple T6030 and T6031 support (just compatible strings) - Samsung Exynos 8855 SoC - Mediatek MT6858 SoC - Rockchip RK3308B and RV1106 SoCs - Airoha EN7523 and AN7563 SoCs Improvements: - Qualcomm TLMM GPIOs are unconditionally marked as wakeup capable - Qualcomm improvements on top of the Qualcomm PDC (power domain controller) irqchip improvements from tglx:s tree - Qualcomm IPQ806x and IPQ9650 non-urgent pin grop fixups - The NPCM8xx driver has been put into shape fixing many pin and group definitions - Some non-urgent Tegra 264 pin assignments are fixed up - Some non-urgent fixups to Airoha AN7581 and AN7583 registers and pin assignments, missing features etc" * tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (130 commits) dt-bindings: pinctrl: Convert TI DA850 pupd to DT schema pinctrl: meson: sync some modify from A4 pinctrl: meson: a4: Add input enable pin configuration pinctrl: realtek: rtd1625: remove unused group name spdif_sel pinctrl: realtek: rtd1625: fix base_bit for VE4 GPIO 13 dt-bindings: pinctrl: microchip,pic32mzda-pinctrl: Convert to DT schema Revert "Merge branch 'ib-rsk7204' into devel" pinctrl: rockchip: Add RV1106 pinctrl support dt-bindings: pinctrl: rockchip: Add RV1106 compatible pinctrl: rockchip: Decode drive strength in the get function pinctrl: fix PINCTRL_GENERIC_MUX not always being selectable pinctrl: airoha: add support of an7563 SoC dt-bindings: pinctrl: airoha: add support of an7563 pin controller pinctrl: airoha: try to find chip scu node by phandle first pinctrl: airoha: add support of en7523 SoC dt-bindings: pinctrl: airoha: add support of en7523 pin controller pinctrl: airoha: an7583: add support for olt pinmux pinctrl: airoha: an7583: add support for pon_alt pinmux pinctrl: airoha: an7583: add support for npu_uart pinmux dt-bindings: pinctrl: airoha: an7583: add missed features ... --- net/mac80211/key.h | 175 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 175 insertions(+) create mode 100644 net/mac80211/key.h (limited to 'net/mac80211/key.h') diff --git a/net/mac80211/key.h b/net/mac80211/key.h new file mode 100644 index 000000000..826e4e938 --- /dev/null +++ b/net/mac80211/key.h @@ -0,0 +1,175 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +/* + * Copyright 2002-2004, Instant802 Networks, Inc. + * Copyright 2005, Devicescape Software, Inc. + * Copyright (C) 2019, 2022-2023 Intel Corporation + */ + +#ifndef IEEE80211_KEY_H +#define IEEE80211_KEY_H + +#include +#include +#include +#include +#include +#include +#include + +#define NUM_DEFAULT_KEYS 4 +#define NUM_DEFAULT_MGMT_KEYS 2 +#define NUM_DEFAULT_BEACON_KEYS 2 +#define INVALID_PTK_KEYIDX 2 /* Keyidx always pointing to a NULL key for PTK */ + +struct ieee80211_local; +struct ieee80211_sub_if_data; +struct ieee80211_link_data; +struct sta_info; + +/** + * enum ieee80211_internal_key_flags - internal key flags + * + * @KEY_FLAG_UPLOADED_TO_HARDWARE: Indicates that this key is present + * in the hardware for TX crypto hardware acceleration. + * @KEY_FLAG_TAINTED: Key is tainted and packets should be dropped. + */ +enum ieee80211_internal_key_flags { + KEY_FLAG_UPLOADED_TO_HARDWARE = BIT(0), + KEY_FLAG_TAINTED = BIT(1), +}; + +enum ieee80211_internal_tkip_state { + TKIP_STATE_NOT_INIT, + TKIP_STATE_PHASE1_DONE, + TKIP_STATE_PHASE1_HW_UPLOADED, +}; + +struct tkip_ctx { + u16 p1k[5]; /* p1k cache */ + u32 p1k_iv32; /* iv32 for which p1k computed */ + enum ieee80211_internal_tkip_state state; +}; + +struct tkip_ctx_rx { + struct tkip_ctx ctx; + u32 iv32; /* current iv32 */ + u16 iv16; /* current iv16 */ +}; + +struct ieee80211_key { + struct ieee80211_local *local; + struct ieee80211_sub_if_data *sdata; + struct sta_info *sta; + + /* for sdata list */ + struct list_head list; + + /* protected by key mutex */ + unsigned int flags; + + union { + struct { + /* protects tx context */ + spinlock_t txlock; + + /* last used TSC */ + struct tkip_ctx tx; + + /* last received RSC */ + struct tkip_ctx_rx rx[IEEE80211_NUM_TIDS]; + + /* number of mic failures */ + u32 mic_failures; + } tkip; + struct { + /* + * Last received packet number.
