vasilito	702ec7efac	feat: relibc S1 — sem_open refcounting + glibc cross-reference assessment ... Phase S1 (Critical Correctness): - sem_open/sem_close: global refcounting via BTreeMap + AtomicUsize - sem_close: decrements refcount, munmaps only at zero - sem_open: reuses existing mapping, O_EXCL returns EEXIST - sem_unlink: marks entry for removal before shm_unlink - va_list parsing: reads mode_t and value from stack after oflag - All 11 sem_* functions verified in libc.so T Phase S2-S4 (Designed, documented): - eventfd() function, signalfd read path, EINTR handling - name canonicalization, cancellation safety - Full plan in local/docs/RELIBC-AGAINST-GLIBC-ASSESSMENT.md Reference: glibc 2.41 cloned to local/reference/glibc/ Boot verified: greeter ready on VT 3 with refcounted semaphores	2026-05-05 21:12:08 +01:00
vasilito	f31522130f	fix: comprehensive boot warnings and exceptions — fixable silenced, unfixable diagnosed ... Build system (5 gaps hardened): - COOKBOOK_OFFLINE defaults to true (fork-mode) - normalize_patch handles diff -ruN format - New 'repo validate-patches' command (25/25 relibc patches) - 14 patched Qt/Wayland/display recipes added to protected list - relibc archive regenerated with current patch chain Boot fixes (fixable): - Full ISO EFI partition: 16 MiB → 1 MiB (matches mini, BIOS hardcoded 2 MiB offset) - D-Bus system bus: absolute /usr/bin/dbus-daemon path (was skipped) - redbear-sessiond: absolute /usr/bin/redbear-sessiond path (was skipped) - daemon framework: silenced spurious INIT_NOTIFY warnings for oneshot_async services (P0-daemon-silence-init-notify.patch) - udev-shim: demoted INIT_NOTIFY warning to INFO (expected for oneshot_async) - relibc: comprehensive named semaphores (sem_open/close/unlink) replacing upstream todo!() stubs - greeterd: Wayland socket timeout 15s → 30s (compositor DRM wait) - greeter-ui: built and linked (header guard unification, sem_compat stubs removed) - mc: un-ignored in both configs, fixed glib/libiconv/pcre2 transitive deps - greeter config: removed stale keymapd dependency from display/greeter services - prefix toolchain: relibc headers synced, _RELIBC_STDLIB_H guard unified Unfixable (diagnosed, upstream): - i2c-hidd: abort on no-I2C-hardware (QEMU) — process::exit → relibc abort - kded6/greeter-ui: page fault 0x8 — Qt library null deref - Thread panics fd != -1 — Rust std library on Redox - DHCP timeout / eth0 MAC — QEMU user-mode networking - hwrngd/thermald — no hardware RNG/thermal in VM - live preload allocation — BIOS memory fragmentation, continues on demand	2026-05-05 20:20:37 +01:00
