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 ... --- security/landlock/cred.c | 69 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 security/landlock/cred.c (limited to 'security/landlock/cred.c') diff --git a/security/landlock/cred.c b/security/landlock/cred.c new file mode 100644 index 000000000..03449c262 --- /dev/null +++ b/security/landlock/cred.c @@ -0,0 +1,69 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * Landlock - Credential hooks + * + * Copyright © 2017-2020 Mickaël Salaün + * Copyright © 2018-2020 ANSSI + * Copyright © 2024-2025 Microsoft Corporation + */ + +#include +#include +#include + +#include "common.h" +#include "cred.h" +#include "ruleset.h" +#include "setup.h" + +static void hook_cred_transfer(struct cred *const new, + const struct cred *const old) +{ + const struct landlock_cred_security *const old_llcred = + landlock_cred(old); + + landlock_get_domain(old_llcred->domain); + *landlock_cred(new) = *old_llcred; +} + +static int hook_cred_prepare(struct cred *const new, + const struct cred *const old, const gfp_t gfp) +{ + hook_cred_transfer(new, old); + return 0; +} + +static void hook_cred_free(struct cred *const cred) +{ + struct landlock_domain *const dom = landlock_cred(cred)->domain; + + if (dom) + landlock_put_domain_deferred(dom); +} + +#ifdef CONFIG_SECURITY_LANDLOCK_LOG + +static int hook_bprm_creds_for_exec(struct linux_binprm *const bprm) +{ + /* Resets for each execution. */ + landlock_cred(bprm->cred)->domain_exec = 0; + return 0; +} + +#endif /* CONFIG_SECURITY_LANDLOCK_LOG */ + +static struct security_hook_list landlock_hooks[] __ro_after_init = { + LSM_HOOK_INIT(cred_prepare, hook_cred_prepare), + LSM_HOOK_INIT(cred_transfer, hook_cred_transfer), + LSM_HOOK_INIT(cred_free, hook_cred_free), + +#ifdef CONFIG_SECURITY_LANDLOCK_LOG + LSM_HOOK_INIT(bprm_creds_for_exec, hook_bprm_creds_for_exec), +#endif /* CONFIG_SECURITY_LANDLOCK_LOG */ +}; + +__init void landlock_add_cred_hooks(void) +{ + security_add_hooks(landlock_hooks, ARRAY_SIZE(landlock_hooks), + &landlock_lsmid); +} -- cgit v1.3.1
