Add three relibc patches (42 total) to close QtNetwork-critical socket gaps:
- P3-inet6-pton-ntop: AF_INET6 address parsing/formatting with RFC 5952
shorthand, IPv4-mapped suffix support
- P3-tcp-sockopt-forward: forward IPPROTO_TCP getsockopt/setsockopt to
scheme daemon instead of hitting todo_skip
- P3-dns-aaaa-getaddrinfo-ipv6: AAAA DNS record queries, lookup_host_v6,
dual-stack getaddrinfo with sockaddr_in6 entries
Also fix P3-tcp-nodelay to use sys_call_wo + from_raw_parts (const) in the
SOL_SOCKET setsockopt fallback — setsockopt sends data to the kernel, not
reads from it.
relibc select_epoll() forced timeout=0 when any FD doesn't support epoll
(e.g. TTY on Redox), causing busy-loop. Poll with 100ms interval instead.
Also add stdint.h to signal/cbindgen.toml sys_includes so signalfd_siginfo
struct types (uint32_t, int32_t) resolve without build errors.
Upstream relibc netdb DNS lookup has two bugs exposed by Rust 2024 edition
strict unsafe handling:
1. packet_data is moved into Box::via into_boxed_slice() but the retry
loop tries to call packet_data.as_ptr() on the moved value. Use the
already-created raw pointer packet_data_ptr instead.
2. close() is a safe function in relibc, so wrapping it in unsafe{}
triggers unused-unsafe (promoted to error by -D unused-unsafe). Remove
the unnecessary unsafe blocks around close() calls.
Patch carries in local/patches/relibc/P3-netdb-lookup-retry-fix.patch and
is applied via the relibc recipe patches list.
Consolidate the active desktop path around redbear-full while landing the greeter/session stack and the runtime fixes needed to keep Wayland and KWin bring-up moving forward.
Keep the relibc compatibility work in tracked local patch carriers and align the recipe with the full durable patch stack so clean reapply and rebuild paths stay reproducible.
Keep the relibc overlay consistent so the generated stdlib header preserves C linkage for strtold and the existing toolchain can still satisfy stale C++ callers while it is refreshed.
Derivative of Redox OS (https://www.redox-os.org) adding:
- AMD GPU driver (amdgpu) via LinuxKPI compat layer
- ext4 filesystem support (ext4d scheme daemon)
- ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG)
- Custom branding (hostname, os-release, boot identity)
Build system is full upstream Redox with RBOS overlay in local/.
Patches for kernel, base, and relibc are symlinked from local/patches/
and protected from make clean/distclean. Custom recipes live in
local/recipes/ with symlinks into the recipes/ search path.
Build: make all CONFIG_NAME=redbear-full
Sync: ./local/scripts/sync-upstream.sh
