vasilito 34360e1e4f feat: P0-P6 kernel scheduler + relibc threading comprehensive implementation 
P0-P2: Barrier SMP, sigmask/pthread_kill races, robust mutexes, RT scheduling, POSIX sched API
P3: PerCpuSched struct, per-CPU wiring, work stealing, load balancing, initial placement
P4: 64-shard futex table, REQUEUE, PI futexes (LOCK_PI/UNLOCK_PI/TRYLOCK_PI), robust futexes, vruntime tracking, min-vruntime SCHED_OTHER selection
P5: setpriority/getpriority, pthread_setaffinity_np, pthread_setname_np, pthread_setschedparam (Redox)
P6: Cache-affine scheduling (last_cpu + vruntime bonus), NUMA topology kernel hints + numad userspace daemon

Stability fixes: make_consistent stores 0 (dead TID fix), cond.rs error propagation, SPIN_COUNT adaptive spinning, Sys::open &str fix, PI futex CAS race, proc.rs lock ordering, barrier destroy

Patches: 33 kernel + 58 relibc patches, all tracked in recipes
Docs: KERNEL-SCHEDULER-MULTITHREAD-IMPROVEMENT-PLAN.md updated, SCHEDULER-REVIEW-FINAL.md created
Architecture: NUMA topology parsing stays userspace (numad daemon), kernel stores lightweight NumaTopology hints

vasilito 24289bf93f feat: supplementary groups + credential syscalls — setgroups/getgroups/RLIMIT 
Kernel (3 files, 32 lines):
- Context.groups: Vec<u32> — supplementary group storage
- CallerCtx.groups — exposed to schemes for access control
- Proc scheme Groups handle — auth-{fd}-groups read/write path
- Fork inheritance — new-context copies parent groups to child

Relibc (4 files, 82 insertions, 84 deletions):
- posix_setgroups()/posix_getgroups() in redox-rt sys.rs
- DynamicProcInfo.groups cache in lib.rs
- setgroups() real impl via thr_fd.dup(auth-{fd}-groups)
- getgroups() kernel-only (no /etc/group fallback)
- initgroups() functional via setgroups()
- getrlimit/setrlimit userspace stubs with defaults

Patches:
- local/patches/kernel/P4-supplementary-groups.patch
- local/patches/relibc/P4-setgroups-getgroups.patch

Docs updated:
- COMPREHENSIVE-OS-ASSESSMENT: credential blocker → RESOLVED
- KERNEL-IPC-CREDENTIAL-PLAN: marked Phases K1-K2,K4 complete
- local/AGENTS.md: credential gap section → RESOLVED

Unblocks: polkit, dbus-daemon, logind, sudo/su, redbear-authd

vasilito 761e0d9de7 state: 36/48 KDE packages build, 12 blocked — honest final state 
The literal task 'build ALL KDE packages' cannot be 100% completed
because 12 packages require upstream dependencies not available on Redox:
- kirigami + plasma* (4): QML JIT disabled — no QQuickWindow/QQmlEngine
- kwin real build (1): Qt6::Sensors port needed
- breeze + kf6-kio + kf6-knewstuff + kde-cli-tools (4): source issues
- plasma extras (3): transitive blockers

What WAS completed:
- Cookbook topological sort fix (root cause — all deps now correct order)
- kf6-attica recipe (183 files, 2.4MB pkgar)
- 12 I2C/GPIO/UCSI daemons archived as durable patches
- Source archival system (make sources)
- Config + all docs synced, no contradictions

vasilito 752bceb3e9 Enable IPv6 foundation in relibc: inet_pton/ntop, TCP socket options, DNS AAAA 
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.

vasilito 65acab85bb Split base cumulative patch and add relibc AIO stubs, KDE recipes 
Base patch extraction (8 topic-grouped patches from the 17k-line monolith):
- P2-ps2d-improvements: PS/2 controller flush/retry, mouse state machine, named producers
- P2-storage-error-handling: AHCI/IDE/NVMe/VirtIO unwrap/expect removal
- P2-usb-pm-and-drivers: suspend/resume, SCSI enablement, staged port fallback
- P2-network-error-handling: e1000/ixgbe/rtl8139/rtl8168d/virtio-net error propagation
- P2-pcid-cfg-access: PCI config I/O port and ECAM graceful fallbacks
- P2-ihdad-hda-stream: InputStream support, public stream types, Debug derives
- P2-init-acpid-wiring: acpid weak dependency on drivers/hwd/pcid-spawner
- P2-misc-daemon-fixes: audiod/usbhidd/zerod graceful degradation

relibc P3-aio.patch: synchronous POSIX AIO fallback (aio_read, aio_write,
aio_error, aio_return, aio_cancel, aio_suspend, aio_fsync, lio_listio)
for Qt6 QIODevice compatibility. 36 patches total in relibc recipe.

KDE recipes: breeze (widget style, decorations disabled), kde-cli-tools
(kioclient, kreadconfig, etc., kdesu disabled).

vasilito 530eb841db Add relibc fenv and sched POSIX implementations 
P3-fenv: x86_64 SSE/x87 inline asm for 10 FP environment functions
(feclearexcept, fegetenv, fegetexceptflag, fegetround, feholdexcept,
feraiseexcept, fesetenv, fesetexceptflag, fesetround, fetestexcept,
feupdateenv) with proper MXCSR and x87 CW register access.

P3-sched: 6 scheduler functions (sched_get_priority_max/min,
sched_getparam, sched_rr_get_interval, sched_setparam,
sched_setscheduler) with EINVAL for bad policy and no-op validation
since Redox has no real-time scheduler.

vasilito cc0e28d282 Wire 9 missing relibc patches into recipe build list (33 total) 2026-04-25 17:38:06 +01:00
vasilito 296861f1ce Fix mc 100% CPU hang: select() non-epoll timeout and signal.h stdint include 
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.

vasilito 843f30ba42 Fix relibc netdb/lookup: use-after-move and unsafe block 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.

vasilito 1cc3b104de Add relibc eventfd MOD patch for init waitpid compatibility 
Eventfd now sets correct file mode bits so init's waitpid loop
can poll on eventfd descriptors without spurious EPERM.

vasilito 50b731f1b7 Red Bear OS — microkernel OS in Rust, based on Redox 
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
