[PATCH v10 0/13] MR1074: Draft: ntdll: Improve Valgrind and GDB integration.
Valgrind support requires a fork, which I've published to https://gitlab.winehq.org/rbernon/valgrind. The fork implements loading DWARF debug info from PE files, instead of the old and broken upstream PDB support. I've tried to upstream these changes a long time ago but didn't receive any feedback. I think we could maybe consider keeping a fork, which I'm happy to maintain, as the changes aren't too large. We may want to investigate adding 32-on-64 support, which may require a bit more changes (to VEX specifically, because its amd64 guest doesn't support segment register manipulation). The changes here are not all related to Valgrind, and I'll create separate MR for those which may make sense independently from Valgrind / GDB. Also included is a suppression file to silent some annoying false positives, many of which are coming from the cross-stack accesses during syscalls, which are confusing Valgrind's stack heuristics. One can try this out with something like: `WINELOADERNOEXEC=1 valgrind --suppressions=tools/valgrind.supp wine64/loader/wine64 wine64/programs/winecfg/winecfg.exe` -- v10: ntdll: Avoid writing to invalid memory in i386 unix dispatcher. ntdll: Fix incorrect i386 call_user_mode_callback CFI. ntdll: Avoid marking freed block header as undefined for valgrind. ntdll: Force HEAP_TAIL_CHECKING_ENABLED flag with valgrind. ntdll: Fix valgrind notifications from ntdll.so. ntdll: Import valgrind headers for PE side ntdll. loader: Implement SystemTap RTLD probes. configure.ac: Check for systemtap sys/sdt.h header. gitlab: Install systemtap-sdt-dev packages. ntdll: Maintain a PE module link map and expose it to GDB. ntdll: Pass a UNICODE_STRING to load_builtin and virtual_map_image. loader: Expose a shadow copy of ld.so link map to GDB. ntdll: Add .cfi_signal_frame to __wine_syscall_dispatcher. https://gitlab.winehq.org/wine/wine/-/merge_requests/1074

If gcc believes + the CFA is in %rsp, then unwinding may fail, because what's at the + CFA is not what gcc "expected" when it constructs the CFIs for the + places where the macros are instantiated. + + But we can't just add a CFI annotation to increase the CFA offset + by 128, to match the sub of 128 from %rsp, because we don't know + whether gcc has chosen %rsp as the CFA at that point, or whether it + has chosen some other register (eg, %rbp). In the latter case, + adding a CFI annotation to change the CFA offset is simply wrong. + + So the solution is to get hold of the CFA using + __builtin_dwarf_cfa(), put it in a known register, and add a + CFI annotation to say what the register is. We choose %rbp for + this (perhaps perversely), because: + + (1) %rbp is already subject to unwinding. If a new register was + chosen then the unwinder would have to unwind it in all stack + traces, which is expensive, and + + (2) %rbp is already subject to precise exception updates in the + JIT. If a new register was chosen, we'd have to have precise + exceptions for it too, which reduces performance of the + generated code. + + However .. one extra complication. We can't just whack the result + of __builtin_dwarf_cfa() into %rbp and then add %rbp to the + list of trashed registers at the end of the inline assembly + fragments; gcc won't allow %rbp to appear in that list. Hence + instead we need to stash %rbp in %r15 for the duration of the asm, + and say that %r15 is trashed instead. gcc seems happy to go with + that. + + Oh .. and this all needs to be conditionalised so that it is + unchanged from before this commit, when compiled with older gccs + that don't support __builtin_dwarf_cfa. Furthermore, since + this header file is freestanding, it has to be independent of + config.h, and so the following conditionalisation cannot depend on + configure time checks. + + Although it's not clear from + 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)', + this expression excludes Darwin. + .cfi directives in Darwin assembly appear to be completely + different and I haven't investigated how they work. + + For even more entertainment value, note we have to use the + completely undocumented __builtin_dwarf_cfa(), which appears to + really compute the CFA, whereas __builtin_frame_address(0) claims + to but actually doesn't.

This + happens automatically for the standard allocator functions such as + malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, + delete[], etc. + + But if your program uses a custom allocator, this doesn't automatically + happen, and Valgrind will not do as well. For example, if you allocate + superblocks with mmap() and then allocates chunks of the superblocks, all + Valgrind's observations will be at the mmap() level and it won't know that + the chunks should be considered separate entities. In Memcheck's case, + that means you probably won't get heap block overrun detection (because + there won't be redzones marked as unaddressable) and you definitely won't + get any leak detection. + + The following client requests allow a custom allocator to be annotated so + that it can be handled accurately by Valgrind. + + VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated + by a malloc()-like function. For Memcheck (an illustrative case), this + does two things: + + - It records that the block has been allocated. This means any addresses + within the block mentioned in error messages will be + identified as belonging to the block. It also means that if the block + isn't freed it will be detected by the leak checker. + + - It marks the block as being addressable and undefined (if 'is_zeroed' is + not set), or addressable and defined (if 'is_zeroed' is set). This + controls how accesses to the block by the program are handled. + + 'addr' is the start of the usable block (ie. after any + redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator + can apply redzones -- these are blocks of padding at the start and end of + each block. Adding redzones is recommended as it makes it much more likely + Valgrind will spot block overruns. `is_zeroed' indicates if the memory is + zeroed (or filled with another predictable value), as is the case for + calloc(). + + VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a + heap block -- that will be used by the client program -- is allocated. + It's best to put it at the outermost level of the allocator if possible; + for example, if you have a function my_alloc() which calls + internal_alloc(), and the client request is put inside internal_alloc(), + stack traces relating to the heap block will contain entries for both + my_alloc() and internal_alloc(), which is probably not what you want. + + For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out + custom blocks from within a heap block, B, that has been allocated with + malloc/calloc/new/etc, then block B will be *ignored* during leak-checking + -- the custom blocks will take precedence. + + VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For + Memcheck, it does two things: + + - It records that the block has been deallocated. This assumes that the + block was annotated as having been allocated via + VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. + + - It marks the block as being unaddressable. + + VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a + heap block is deallocated. + + VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For + Memcheck, it does four things: + + - It records that the size of a block has been changed. This assumes that + the block was annotated as having been allocated via + VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. + + - If the block shrunk, it marks the freed memory as being unaddressable. + + - If the block grew, it marks the new area as undefined and defines a red + zone past the end of the new block. + + - The V-bits of the overlap between the old and the new block are preserved. + + VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block + and before deallocation of the old block. + + In many cases, these three client requests will not be enough to get your + allocator working well with Memcheck. More specifically, if your allocator + writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call + will be necessary to mark the memory as addressable just before the zeroing + occurs, otherwise you'll get a lot of invalid write errors. For example, + you'll need to do this if your allocator recycles freed blocks, but it + zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). + Alternatively, if your allocator reuses freed blocks for allocator-internal + data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. + + Really, what's happening is a blurring of the lines between the client + program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the + memory should be considered unaddressable to the client program, but the + allocator knows more than the rest of the client program and so may be able + to safely access it.

Since the change to build the preloader as PIE, the GDB integration was broken: 1) the executable has a DT_DEBUG dynamic entry and GDB prefers it over the _r_debug static symbol. Fixed this by writing the _r_debug address to DT_DEBUG in the preloader. 2) the _dl_debug_state breakpoint hook is not working anymore. The symbol is still required to be present for GDB to be happy, and with DT_DEBUG fixed, GDB correctly reloads the solib list, but it doesn't load their symbols dynamically (still does after a `sharedlib` command). I suspect that its _dl_debug_state breakpoint gets ovewritten somehow. So I'm now using SystemTap RTLD probes (as described in https://sourceware.org/git/?p=glibc.git;a=blob;f=elf/rtld-debugger-interface...) to notify the debugger of link_map changes instead. This requires some additional packages to be installed. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1074#note_43318
