* | Narrow pointer bounds when appropriatePaul Eggert2017-12-121-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This typically occurs in a storage manager, where the caller is expected to access only the newly-allocated object, instead of using the returned value to access unrelated parts of the heap. * src/alloc.c (allocate_string, allocate_string_data) (compact_small_strings, find_string_data_in_pure) (sweep_strings, setup_on_free_list, allocate_vectorlike (pure_alloc): * src/bytecode.c (exec_byte_code): * src/callint.c (Fcall_interactively): * src/dispnew.c (scrolling): * src/editfns.c (styled_format): * src/frame.c (xrdb_get_resource, x_get_resource_string): * src/fringe.c (Fdefine_fringe_bitmap): * src/gmalloc.c (malloc, realloc, aligned_alloc): Narrow pointer bounds when appropriate. * src/alloc.c (SDATA_OF_STRING): * src/lisp.h (make_lisp_symbol) [__CHKP__]: Widen bounds here, though. * src/bytecode.c, src/callint.c, src/dispnew.c, src/editfns.c: * src/emacs.c, src/frame.c, src/fringe.c: Include ptr-bounds.h. * src/ptr-bounds.h (ptr_bounds_clip): New function.
* | Port to gcc -fcheck-pointer-boundsPaul Eggert2017-12-121-1/+5
|/ | | | | | | | | | | | | | | | | | | | | | This is a minimal port, just to get Emacs running; it does not attempt to make the pointer bounds at all tight. * src/ptr-bounds.h: New file. * src/alloc.c, src/gmalloc.c: Include it. * src/alloc.c (live_string_holding, live_cons_holding) (live_symbol_holding, live_misc_holding, garbage_collect_1) (sweep_conses, sweep_floats): * src/gmalloc.c (malloc_initialize_1, _free_internal_nolock) (_realloc_internal_nolock): Widen pointer bounds as necessary. We're in a memory allocator so this is OK. * src/lisp.h (lisp_h_XSYMBOL, make_lisp_symbol) [__CHKP__]: Do not convert from pointer to integer and back again, so that GCC does not lose track of pointer bounds. (XSYMBOL) [__CHKP__ && !USE_LSB_TAG]: Now a compile-time error. Although it's possible to support both -fcheck-pointer-bounds and --with-wide-int, it's more work; keep things simple for now. (DEFINE_LISP_SYMBOL) [__CHKP__]: Now a no-op, to avoid trouble with unbounded pointers.
* Use hybrid malloc for FreeBSD (Bug#28308)Noam Postavsky2017-11-041-5/+6
| | | | | | | | FreeBSD aarch64 does not provide sbrk, so gmalloc cannot be used; when using system malloc dumping does not work correctly (allocated data is invalid after dumping). * configure.ac: Set hybrid_malloc for freebsd. * src/gmalloc.c (gdefault_morecore) [!HAVE_SBRK]: Don't call sbrk.
* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-9/+9
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
* Remove malloc_find_address relicPaul Eggert2017-06-211-11/+1
| | | | | * src/gmalloc.c (register_heapinfo, _malloc_internal_nolock): Omit unnecessary initialization.
* Fix temacs hybrid_malloc core dumpPaul Eggert2017-06-211-30/+41
| | | | | | | | | | | | | | | | | | | | | | | Without this patch, ./temacs would dump core sometimes on Fedora 25 x86-64. The problem was that the hybrid allocator assumed that all pointers into bss_sbrk_buffer are allocated via gmalloc. This assumption is not true on Fedora, because the standard memory allocator calls gdefault_morecore, which means its blocks are interleaved with our blocks. Usually the code happened to work, because our data structures agreed with the glibc data structures, but this was merely luck due to a shared pedigree, and as glibc mutates our luck has run out. * src/gmalloc.c (ALLOCATED_BEFORE_DUMPING) [HYBRID_MALLOC]: Remove; no longer needed. (BLOCK): Use unsigned division, as that does the right thing near zero. (register_heapinfo, __malloc_internal_nolock, __free_internal_nolock) (_realloc_internal_nolock): Big blocks now have type -1, not 0, as 0 now means the block is not ours. (morecore_nolock): Omit now-unnecessary casts to size_t. (allocated_via_gmalloc) [HYBRID_MALLOC]: New function. (hybrid_free, hybrid_realloc) [HYBRID_MALLOC]: Use it, to avoid calling the wrong free or realloc function in some cases.

They were lost in a4817d8 but calloc is still (marginally) used in code statically liked with emacs, so hybrid_calloc is needed. Also, in the non-hybrid case, we can't get rid of calloc anyway as other libraries liked with emacs may need it. * src/conf_post.h: Restore redefinition of calloc to hybrid_calloc.
