Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header. 2020-01-18 09:38:21 +01:00			`/*`

Kernel: Add a LoopbackAdapter for talking to yourself via 127.0.0.1. Choosing adapter for transmit is done by adapter_for_route_to(IPv4Address). This is just hard-coded logic right now but can be expanded to support a proper routing table. Also start moving kernel networking code into Kernel/Net/. 2019-04-02 15:46:44 +02:00			`#pragma once`

Kernel: Introduce the NetworkingManagement singleton Instead of initializing network adapters in init.cpp, let's move that logic into a separate class to handle this. Also, it seems like a good idea to shift responsiblity on enumeration of network adapters after the boot process, so this singleton will take care of finding the appropriate network adapter when asked to with an IPv4 address or interface name. With this change being merged, we simplify the creation logic of NetworkAdapter derived classes, so we enumerate the PCI bus only once, searching for driver candidates when doing so, and we let each driver to test if it is resposible for the specified PCI device. 2021-06-04 07:43:16 +03:00

Kernel: Switch singletons to use new Singleton class MemoryManager cannot use the Singleton class because MemoryManager::initialize is called before the global constructors are run. That caused the Singleton to be re-initialized, causing it to create another MemoryManager instance. Fixes #3226 2020-08-24 19:35:19 -06:00			`LoopbackAdapter();`
AK: Revert Eternal<T> for now since it doesn't work as intended. 2019-04-05 05:10:18 +02:00
