vm_map nentries/name adjustments were gated to explicit 6/7.0x/8.x cases, so
7.5x (7.20-7.61) and 9.x+ got no adjustment. That broke locating the inject
target on install and left PROC_INFO/PROC_LIST/PROC_MAPS names empty/truncated.
Switch all three sites (installer proc_elf, debugger proc_elf, scan) to a
>= 6.x threshold.
- find_pid: locate SceShellCore via sysctl KERN_PROC_PID/ki_comm
(firmware-agnostic) instead of a per-FW struct proc name offset.
- install_kernel_patch: skip the write when the jailbreak already set the
bits, preventing a kernel panic on 7.61.
- proc_field_offsets: switch to threshold offsets (corrects 7.5x and adds
10/11/12.x).
Features
- Option E: CMD_PROC_MAPS now augments the vm_map list with Sony-aux regions
(SceGnm/SceAgc/JIT/DMEM) that bypass vm_map, discovered via a kernel-side
x86-64 page-table walk over the DMAP. FW-agnostic (runtime pmap-offset
discovery + ground-truth validation); falls back to the plain vm_map result
on any failure.
- Hybrid memory-read path: reads route DMAP-direct for vm_map-absent (aux)
regions and mdbg otherwise (and as fallback), making aux scans ~4x faster on
both the CMD_PROC_READ and server-side scan paths. No protocol change;
byte-identical results.
Fixes
- SW breakpoint wait4-race: eliminate the multi-threaded epilogue-BP SIGSEGV
storm (stale TRAP_TRACE/TRAP_BRKPT absorbers, PT_LWPINFO-gated sibling
rewind, RIP-only fast caches, authid bump around rearm, SIGSEGV-storm guard).
- AOB-multi scan: unique-mode now exits only on invalidated >= pat_count
(matches the original), fixing wrongly-reported-unique / truncated scans.
Performance / robustness
- BP-event latency: select timeout 1000->100 us, poll 100->50 us.
- Per-command debug-state locking (0xBDBB) to prevent BP-slot-table corruption
under concurrent clients.
- Installer: double-load guard (loopback 744 probe), relocation pre-apply plus
batched ptrace_io for faster injection, wait4 instead of a fixed sleep.
Refactor
- Firmware detection rewritten to a direct switch(fw & 0xffff0000) with
per-case version annotations; behavior-preserving (verified equivalent).
Version 1.2.3 -> 1.2.4.
PS5 debugger payload, inspired by Ctn's ps5debug 1.0b5 and
wire-compatible with it. Runs the wire-protocol server inside
SceShellCore via an umtx-loaded installer that injects the embedded
debugger ELF.
Features: process scan/RPC/ELF-inject, on-console scan, full
debugger (breakpoints, watchpoints, single-step, regs/FP/DR access),
kernel R/W, server-side Zydis disassembly, on-console Keystone
assembler (0xBDAA0024), foreground-app metadata (0xBDDD0006),
server-side RBP stack walk (CMD_PROC_READ_STACK), klog forwarder
(TCP 3232), rest-mode survival and a lot more.
Supports FW families 3.x / 4.0 / 4.x (incl. 4.51) / 5.x / 6.x /
7.x / 7.5x / 8.x via the kpatch routine in installer/source/main.c.
GPL-3.0-only.
