2024-12-20Fix GC compaction crash when using local variables in evalPeter Zhu
If we have local variables outside of the eval, the local variables names are IDs. We convert these IDs to char * using rb_id2name. However, these char * are actually Ruby strings, which may be embedded. This means that it is not safe to rb_id2name and call any potential GC entrypoints because if a GC compaction runs, the embedded string may move and the pointer will change. For example, if you compile with `-DRGENGC_CHECK_MODE=1`, then the following script will crash: GC.auto_compact = :empty GC.stress = true o = Object.new eval("def o.m(k: 0) k end") The crash message is: test.rb:6: [BUG] Local with constant_id 1 does not exist ruby 3.4.0dev (2024-12-17T18:34:57Z prism-local-compac.. 434346726c) +PRISM [arm64-darwin24] -- C level backtrace information ------------------------------------------- miniruby(rb_print_backtrace+0x24) [0x10312fec4] vm_dump.c:823 miniruby(rb_print_backtrace) (null):0 miniruby(rb_vm_bugreport+0x2d4) [0x1031301b8] vm_dump.c:1155 miniruby(rb_bug_without_die_internal+0xa8) [0x102dd6a94] error.c:1097 miniruby(rb_bug+0x28) [0x102dd6b00] error.c:1115 miniruby(pm_lookup_local_index+0xec) [0x102d61e4c] prism_compile.c:1237 miniruby(pm_compile_node+0x45d0) [0x102d252f4] prism_compile.c:9334 miniruby(pm_compile_node+0x1864) [0x102d22588] prism_compile.c:8650 miniruby(pm_compile_node+0x65ec) [0x102d27310] prism_compile.c:9897 miniruby(pm_compile_scope_node+0x3008) [0x102d77bcc] prism_compile.c:6584 miniruby(pm_compile_node+0x5ec4) [0x102d26be8] prism_compile.c:9768 miniruby(pm_iseq_compile_node+0xac) [0x102d20bf0] prism_compile.c:10069 miniruby(pm_iseq_new_with_opt_try+0x2c) [0x102e7d088] iseq.c:1029 miniruby(rb_protect+0x108) [0x102dea9bc] eval.c:1033 miniruby(pm_iseq_new_with_opt+0x264) [0x102e7c444] iseq.c:1082 miniruby(pm_iseq_new_eval+0xec) [0x102e7c8e0] iseq.c:961 miniruby(pm_eval_make_iseq+0x594) [0x1031209cc] vm_eval.c:1770 miniruby(eval_make_iseq+0x54) [0x103120068] vm_eval.c:1799 Notes: Merged: https://github.com/ruby/ruby/pull/12374

2024-12-13Fix use-after-free in ep in Proc#dup for ifunc procsPeter Zhu
[Bug #20950] ifunc proc has the ep allocated in the cfunc_proc_t which is the data of the TypedData object. If an ifunc proc is duplicated, the ep points to the ep of the source object. If the source object is freed, then the ep of the duplicated object now points to a freed memory region. If we try to use the ep we could crash. For example, the following script crashes: p = { a: 1 }.to_proc 100.times do p = p.dup GC.start p.call rescue ArgumentError end This commit changes ifunc proc to also duplicate the ep when it is duplicated.

2024-11-29[Bug #20915] Fix SEGV with `TracePoint#parameters` and aliased C methodviralpraxis
The following snippet results with a SEGV: ```ruby C = Class.new do alias_method :new_to_s, :to_s end TracePoint.new(:c_call, &:parameters).enable { C.new.new_to_s } ``` at MRI 3.3.6 and ruby 3.4.0dev The root cause of the issue lies in the `rb_tracearg_parameters` function within the `RUBY_EVENT_C_RETURN` branch. Specifically, when the invoked method is an alias for a C function, `rb_method_entry_without_refinements(..., trace_arg->called_id, ...)` may return NULL. In that case we can fallback to `trace_arg->id`. Notes: Merged: https://github.com/ruby/ruby/pull/12186

This avoids the allocation / array copy for things like `[:a, :b].include?(x)`. This adds a BOP for include? and tracks redefinition for it on Array.
