63 | | |
64 | | The resulting executables will still run without Valgrind, just a |
65 | | little bit more slowly than they otherwise would, but otherwise |
66 | | unchanged. When not running on valgrind, each client request |
67 | | consumes very few (eg. 7) instructions, so the resulting performance |
68 | | loss is negligible unless you plan to execute client requests |
69 | | millions of times per second. Nevertheless, if that is still a |
70 | | problem, you can compile with the NVALGRIND symbol defined (gcc |
71 | | -DNVALGRIND) so that client requests are not even compiled in. */ |

237 | | |
238 | | The assembly code sequences for all architectures is in this one |
239 | | file. This is because this file must be stand-alone, and we don't |
240 | | want to have multiple files. |
241 | | |
242 | | For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default |
243 | | value gets put in the return slot, so that everything works when |
244 | | this is executed not under Valgrind. Args are passed in a memory |
245 | | block, and so there's no intrinsic limit to the number that could |
246 | | be passed, but it's currently five. |
247 | | |
248 | | The macro args are: |
249 | | _zzq_rlval result lvalue |
250 | | _zzq_default default value (result returned when running on real CPU) |
251 | | _zzq_request request code |
252 | | _zzq_arg1..5 request params |
253 | | |
254 | | The other two macros are used to support function wrapping, and are |
255 | | a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the |
256 | | guest's NRADDR pseudo-register and whatever other information is |
257 | | needed to safely run the call original from the wrapper: on |
258 | | ppc64-linux, the R2 value at the divert point is also needed. This |
259 | | information is abstracted into a user-visible type, OrigFn. |
260 | | |
261 | | VALGRIND_CALL_NOREDIR_* behaves the same as the following on the |
262 | | guest, but guarantees that the branch instruction will not be |
263 | | redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64: |
264 | | branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a |
265 | | complete inline asm, since it needs to be combined with more magic |
266 | | inline asm stuff to be useful. |

1226 | | /* This section defines magic (a.k.a appalling-hack) macros for doing |
1227 | | guaranteed-no-redirection macros, so as to get from function |
1228 | | wrappers to the functions they are wrapping. The whole point is to |
1229 | | construct standard call sequences, but to do the call itself with a |
1230 | | special no-redirect call pseudo-instruction that the JIT |
1231 | | understands and handles specially. This section is long and |
1232 | | repetitious, and I can't see a way to make it shorter. |
1233 | | |
1234 | | The naming scheme is as follows: |
1235 | | |
1236 | | CALL_FN_{W,v}_{v,W,WW,WWW,WWWW,5W,6W,7W,etc} |
1237 | | |
1238 | | 'W' stands for "word" and 'v' for "void". Hence there are |
1239 | | different macros for calling arity 0, 1, 2, 3, 4, etc, functions, |
1240 | | and for each, the possibility of returning a word-typed result, or |
1241 | | no result. |

1756 | | /* This is all pretty complex. It's so as to make stack unwinding |
1757 | | work reliably. See bug 243270. The basic problem is the sub and |
1758 | | add of 128 of %rsp in all of the following macros. If gcc believes |
1759 | | the CFA is in %rsp, then unwinding may fail, because what's at the |
1760 | | CFA is not what gcc "expected" when it constructs the CFIs for the |
1761 | | places where the macros are instantiated. |
1762 | | |
1763 | | But we can't just add a CFI annotation to increase the CFA offset |
1764 | | by 128, to match the sub of 128 from %rsp, because we don't know |
1765 | | whether gcc has chosen %rsp as the CFA at that point, or whether it |
1766 | | has chosen some other register (eg, %rbp). In the latter case, |
1767 | | adding a CFI annotation to change the CFA offset is simply wrong. |
1768 | | |
1769 | | So the solution is to get hold of the CFA using |
1770 | | __builtin_dwarf_cfa(), put it in a known register, and add a |
1771 | | CFI annotation to say what the register is. We choose %rbp for |
1772 | | this (perhaps perversely), because: |
1773 | | |
1774 | | (1) %rbp is already subject to unwinding. If a new register was |
1775 | | chosen then the unwinder would have to unwind it in all stack |
1776 | | traces, which is expensive, and |
1777 | | |
1778 | | (2) %rbp is already subject to precise exception updates in the |
1779 | | JIT. If a new register was chosen, we'd have to have precise |
1780 | | exceptions for it too, which reduces performance of the |
1781 | | generated code. |
1782 | | |
1783 | | However .. one extra complication. We can't just whack the result |
1784 | | of __builtin_dwarf_cfa() into %rbp and then add %rbp to the |
1785 | | list of trashed registers at the end of the inline assembly |
1786 | | fragments; gcc won't allow %rbp to appear in that list. Hence |
1787 | | instead we need to stash %rbp in %r15 for the duration of the asm, |
1788 | | and say that %r15 is trashed instead. gcc seems happy to go with |
1789 | | that. |
1790 | | |
1791 | | Oh .. and this all needs to be conditionalised so that it is |
1792 | | unchanged from before this commit, when compiled with older gccs |
1793 | | that don't support __builtin_dwarf_cfa. Furthermore, since |
1794 | | this header file is freestanding, it has to be independent of |
1795 | | config.h, and so the following conditionalisation cannot depend on |
1796 | | configure time checks. |
1797 | | |
1798 | | Although it's not clear from |
1799 | | 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)', |
1800 | | this expression excludes Darwin. |
1801 | | .cfi directives in Darwin assembly appear to be completely |
1802 | | different and I haven't investigated how they work. |
1803 | | |
1804 | | For even more entertainment value, note we have to use the |
1805 | | completely undocumented __builtin_dwarf_cfa(), which appears to |
1806 | | really compute the CFA, whereas __builtin_frame_address(0) claims |
1807 | | to but actually doesn't. See |

1842 | | macros. In order not to trash the stack redzone, we need to drop |
1843 | | %rsp by 128 before the hidden call, and restore afterwards. The |
1844 | | nastyness is that it is only by luck that the stack still appears |
1845 | | to be unwindable during the hidden call - since then the behaviour |
1846 | | of any routine using this macro does not match what the CFI data |
1847 | | says. Sigh. |
1848 | | |
1849 | | Why is this important? Imagine that a wrapper has a stack |
1850 | | allocated local, and passes to the hidden call, a pointer to it. |
1851 | | Because gcc does not know about the hidden call, it may allocate |
1852 | | that local in the redzone. Unfortunately the hidden call may then |
1853 | | trash it before it comes to use it. So we must step clear of the |
1854 | | redzone, for the duration of the hidden call, to make it safe. |
1855 | | |
1856 | | Probably the same problem afflicts the other redzone-style ABIs too |
1857 | | (ppc64-linux); but for those, the stack is |
1858 | | self describing (none of this CFI nonsense) so at least messing |

7422 | | /* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing |
7423 | | when heap blocks are allocated in order to give accurate results. This |
7424 | | happens automatically for the standard allocator functions such as |
7425 | | malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, |
7426 | | delete[], etc. |
7427 | | |
7428 | | But if your program uses a custom allocator, this doesn't automatically |
7429 | | happen, and Valgrind will not do as well. For example, if you allocate |
7430 | | superblocks with mmap() and then allocates chunks of the superblocks, all |
7431 | | Valgrind's observations will be at the mmap() level and it won't know that |
7432 | | the chunks should be considered separate entities. In Memcheck's case, |
7433 | | that means you probably won't get heap block overrun detection (because |
7434 | | there won't be redzones marked as unaddressable) and you definitely won't |
7435 | | get any leak detection. |
7436 | | |
7437 | | The following client requests allow a custom allocator to be annotated so |
7438 | | that it can be handled accurately by Valgrind. |
7439 | | |
7440 | | VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated |
7441 | | by a malloc()-like function. For Memcheck (an illustrative case), this |
7442 | | does two things: |
7443 | | |
7444 | | - It records that the block has been allocated. This means any addresses |
7445 | | within the block mentioned in error messages will be |
7446 | | identified as belonging to the block. It also means that if the block |
7447 | | isn't freed it will be detected by the leak checker. |
7448 | | |
7449 | | - It marks the block as being addressable and undefined (if 'is_zeroed' is |
7450 | | not set), or addressable and defined (if 'is_zeroed' is set). This |
7451 | | controls how accesses to the block by the program are handled. |
7452 | | |
7453 | | 'addr' is the start of the usable block (ie. after any |
7454 | | redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator |
7455 | | can apply redzones -- these are blocks of padding at the start and end of |
7456 | | each block. Adding redzones is recommended as it makes it much more likely |
7457 | | Valgrind will spot block overruns. `is_zeroed' indicates if the memory is |
7458 | | zeroed (or filled with another predictable value), as is the case for |
7459 | | calloc(). |
7460 | | |
7461 | | VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a |
7462 | | heap block -- that will be used by the client program -- is allocated. |
7463 | | It's best to put it at the outermost level of the allocator if possible; |
7464 | | for example, if you have a function my_alloc() which calls |
7465 | | internal_alloc(), and the client request is put inside internal_alloc(), |
7466 | | stack traces relating to the heap block will contain entries for both |
7467 | | my_alloc() and internal_alloc(), which is probably not what you want. |
7468 | | |
7469 | | For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out |
7470 | | custom blocks from within a heap block, B, that has been allocated with |
7471 | | malloc/calloc/new/etc, then block B will be *ignored* during leak-checking |
7472 | | -- the custom blocks will take precedence. |
7473 | | |
7474 | | VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For |
7475 | | Memcheck, it does two things: |
7476 | | |
7477 | | - It records that the block has been deallocated. This assumes that the |
7478 | | block was annotated as having been allocated via |
7479 | | VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. |
7480 | | |
7481 | | - It marks the block as being unaddressable. |
7482 | | |
7483 | | VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a |
7484 | | heap block is deallocated. |
7485 | | |
7486 | | VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For |
7487 | | Memcheck, it does four things: |
7488 | | |
7489 | | - It records that the size of a block has been changed. This assumes that |
7490 | | the block was annotated as having been allocated via |
7491 | | VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. |
7492 | | |
7493 | | - If the block shrunk, it marks the freed memory as being unaddressable. |
7494 | | |
7495 | | - If the block grew, it marks the new area as undefined and defines a red |
7496 | | zone past the end of the new block. |
7497 | | |
7498 | | - The V-bits of the overlap between the old and the new block are preserved. |
7499 | | |
7500 | | VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block |
7501 | | and before deallocation of the old block. |
7502 | | |
7503 | | In many cases, these three client requests will not be enough to get your |
7504 | | allocator working well with Memcheck. More specifically, if your allocator |
7505 | | writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call |
7506 | | will be necessary to mark the memory as addressable just before the zeroing |
7507 | | occurs, otherwise you'll get a lot of invalid write errors. For example, |
7508 | | you'll need to do this if your allocator recycles freed blocks, but it |
7509 | | zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). |
7510 | | Alternatively, if your allocator reuses freed blocks for allocator-internal |
7511 | | data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. |
7512 | | |
7513 | | Really, what's happening is a blurring of the lines between the client |
7514 | | program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the |
7515 | | memory should be considered unaddressable to the client program, but the |
7516 | | allocator knows more than the rest of the client program and so may be able |
7517 | | to safely access it. Extra client requests are necessary for Valgrind to |
7518 | | understand the distinction between the allocator and the rest of the |
7519 | | program. |

7549 | | The flag VALGRIND_MEMPOOL_METAPOOL specifies that the pieces of memory |
7550 | | associated with the pool using VALGRIND_MEMPOOL_ALLOC will be used |
7551 | | by the application as superblocks to dole out MALLOC_LIKE blocks using |
7552 | | VALGRIND_MALLOCLIKE_BLOCK. In other words, a meta pool is a "2 levels" |
7553 | | pool : first level is the blocks described by VALGRIND_MEMPOOL_ALLOC. |
7554 | | The second level blocks are described using VALGRIND_MALLOCLIKE_BLOCK. |
7555 | | Note that the association between the pool and the second level blocks |
7556 | | is implicit : second level blocks will be located inside first level |
7557 | | blocks. It is necessary to use the VALGRIND_MEMPOOL_METAPOOL flag |
7558 | | for such 2 levels pools, as otherwise valgrind will detect overlapping |
7559 | | memory blocks, and will abort execution (e.g. during leak search). |
7560 | | |
7561 | | Such a meta pool can also be marked as an 'auto free' pool using the flag |
7562 | | VALGRIND_MEMPOOL_AUTO_FREE, which must be OR-ed together with the |
7563 | | VALGRIND_MEMPOOL_METAPOOL. For an 'auto free' pool, VALGRIND_MEMPOOL_FREE |
7564 | | will automatically free the second level blocks that are contained |
7565 | | inside the first level block freed with VALGRIND_MEMPOOL_FREE. |
7566 | | In other words, calling VALGRIND_MEMPOOL_FREE will cause implicit calls |
7567 | | to VALGRIND_FREELIKE_BLOCK for all the second level blocks included |
7568 | | in the first level block. |
7569 | | Note: it is an error to use the VALGRIND_MEMPOOL_AUTO_FREE flag |
7570 | | without the VALGRIND_MEMPOOL_METAPOOL flag. |
