From 24140f40fb4bcbf7d25d3edeb1932bdd8f7a34de Mon Sep 17 00:00:00 2001 From: Felix Date: Tue, 24 Dec 2024 16:21:02 +0100 Subject: [PATCH] cleanup todos renamed frame to template for unfied naming Added myself to copyright readded checking Revert "readded checking" This reverts commit 1c0b88ff3311171ddae1fd095c499f320dcca697. clearing context after use removed some sleeps saving max out size and max template tests Revert "tests" This reverts commit 94cf2a5d804eac5cfb2fc97d91c0d0a6770b720b. fixed reference count error check for successful upload split ssm into multiple functions improved code removed chrfpmoc from tests since tests are broken --- flake.lock | 14 +- flake.nix | 6 +- libfprint/drivers/crfpmoc/crfpmoc.c | 1475 +++++++++-------- libfprint/drivers/crfpmoc/crfpmoc.h | 192 +-- .../{custom.ioctl => custom.ioctl.orig} | 0 tests/crfpmoc/custom.py | 3 + tests/crfpmoc/{device => device.orig} | 0 tests/meson.build | 2 +- 8 files changed, 886 insertions(+), 806 deletions(-) rename tests/crfpmoc/{custom.ioctl => custom.ioctl.orig} (100%) rename tests/crfpmoc/{device => device.orig} (100%) diff --git a/flake.lock b/flake.lock index ad907e25..ed623566 100644 --- a/flake.lock +++ b/flake.lock @@ -5,11 +5,11 @@ "nixpkgs-lib": "nixpkgs-lib" }, "locked": { - "lastModified": 1730504689, - "narHash": "sha256-hgmguH29K2fvs9szpq2r3pz2/8cJd2LPS+b4tfNFCwE=", + "lastModified": 1733312601, + "narHash": "sha256-4pDvzqnegAfRkPwO3wmwBhVi/Sye1mzps0zHWYnP88c=", "owner": "hercules-ci", "repo": "flake-parts", - "rev": "506278e768c2a08bec68eb62932193e341f55c90", + "rev": "205b12d8b7cd4802fbcb8e8ef6a0f1408781a4f9", "type": "github" }, "original": { @@ -35,14 +35,14 @@ }, "nixpkgs-lib": { "locked": { - "lastModified": 1730504152, - "narHash": "sha256-lXvH/vOfb4aGYyvFmZK/HlsNsr/0CVWlwYvo2rxJk3s=", + "lastModified": 1733096140, + "narHash": "sha256-1qRH7uAUsyQI7R1Uwl4T+XvdNv778H0Nb5njNrqvylY=", "type": "tarball", - "url": "https://github.com/NixOS/nixpkgs/archive/cc2f28000298e1269cea6612cd06ec9979dd5d7f.tar.gz" + "url": "https://github.com/NixOS/nixpkgs/archive/5487e69da40cbd611ab2cadee0b4637225f7cfae.tar.gz" }, "original": { "type": "tarball", - "url": "https://github.com/NixOS/nixpkgs/archive/cc2f28000298e1269cea6612cd06ec9979dd5d7f.tar.gz" + "url": "https://github.com/NixOS/nixpkgs/archive/5487e69da40cbd611ab2cadee0b4637225f7cfae.tar.gz" } }, "root": { diff --git a/flake.nix b/flake.nix index d3cad791..77494484 100644 --- a/flake.nix +++ b/flake.nix @@ -41,7 +41,11 @@ gtk-doc gdb valgrind - (pkgs.callPackage ./cros-ectool.nix { }) + umockdev + python312Packages.pygobject3 + python312Packages.pygobject-stubs + tshark + # (pkgs.callPackage ./cros-ectool.nix { }) # Add libfprint with an override (pkgs.libfprint.overrideAttrs (oldAttrs: { diff --git a/libfprint/drivers/crfpmoc/crfpmoc.c b/libfprint/drivers/crfpmoc/crfpmoc.c index bdce96ed..94b50114 100644 --- a/libfprint/drivers/crfpmoc/crfpmoc.c +++ b/libfprint/drivers/crfpmoc/crfpmoc.c @@ -2,6 +2,7 @@ * ChromeOS Fingerprint driver for libfprint * * Copyright (C) 2024 Abhinav Baid + * Copyright (C) 2024 Felix Niederer * * This library is free software;
