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			`/*`

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt * 2021-04-22 01:24:48 -07:00			`* SPDX-License-Identifier: BSD-2-Clause`

Kernel+LibC+Userland: Start working on an IPv4 socket backend. The first userland networking program will be "ping" :^) 2019-03-12 15:51:42 +01:00			`#pragma once`

LibC: Add most of the "header may make visible" dependencies from POSIX 2023-07-15 15:22:45 +02:00			`// Includes essentially mandated by POSIX:`

LibC: Include additional headers in <arpa/inet.h> According to the Single UNIX Specification, Version 2 the <arpa/inet.h> header may optionally include <netinet/in.h> and <inttypes.h>. This helps with porting software like c-ray that expects this to be the case. 2021-04-10 14:33:18 +02:00			`#include <inttypes.h>`

LibC: Add INET_ADDRSTRLEN define 2019-05-16 09:50:13 +02:00			`#define INET_ADDRSTRLEN 16`
LibC: Add a definition for `INET6_ADDRSTRLEN` Although serenity doesn't implement IPv6 yet, applications will often declare buffers to be of size `INET6_ADDRSTRLEN` so it's guaranteed to work in both IPv4 / IPv6 environments. This is needed specifically for a port of Flexible IO Tester https://fio.readthedocs.io This is standardized here: https://pubs.opengroup.org/onlinepubs/009695399/basedefs/netinet/in.h.html 2021-04-19 22:24:56 -07:00			`#define INET6_ADDRSTRLEN 46`
