* malloc: Update comments about chunk layoutFlorian Weimer2016-10-281-10/+30
|
* sysmalloc: Initialize previous size field of mmaped chunksFlorian Weimer2016-10-281-0/+1
| | | | | With different encodings of the header, the previous zero initialization may be insufficient and produce an invalid encoding.
* malloc: Use accessors for chunk metadata accessFlorian Weimer2016-10-283-70/+91
| | | | | This change allows us to change the encoding of these struct members in a centralized fashion.
* Static inline functions for mallopt helpersSiddhesh Poyarekar2016-10-271-34/+93
| | | | | | | | | | | | | | | Make mallopt helper functions for each mallopt parameter so that it can be called consistently in other areas, like setting tunables. * malloc/malloc.c (do_set_mallopt_check): New function. (do_set_mmap_threshold): Likewise. (do_set_mmaps_max): Likewise. (do_set_top_pad): Likewise. (do_set_perturb_byte): Likewise. (do_set_trim_threshold): Likewise. (do_set_arena_max): Likewise. (do_set_arena_test): Likewise. (__libc_mallopt): Use them.
* malloc: Remove malloc_get_state, malloc_set_state [BZ #19473]Florian Weimer2016-10-265-100/+480
| | | | | | | | | | | | After the removal of __malloc_initialize_hook, newly compiled Emacs binaries are no longer able to use these interfaces. malloc_get_state is only used during the Emacs build process, so we provide a stub implementation only. Existing Emacs binaries will not call this stub function, but still reference the symbol. The rewritten tst-mallocstate test constructs a dumped heap which should approximates what existing Emacs binaries pass to glibc malloc.
* Remove redundant definitions of M_ARENA_* macrosSiddhesh Poyarekar2016-10-261-5/+0
| | | | | | | | | The M_ARENA_MAX and M_ARENA_TEST macros are defined in malloc.c as well as malloc.h, and the former is unnecessary. This patch removes the duplicate. Tested on x86_64 to verify that the generated code remains unchanged barring changed line numbers to __malloc_assert. * malloc/malloc.c (M_ARENA_TEST, M_ARENA_MAX): Remove.
* Document the M_ARENA_* mallopt parametersSiddhesh Poyarekar2016-10-261-1/+0
| | | | | | | | | | | The M_ARENA_* mallopt parameters are in wide use in production to control the number of arenas that a long lived process creates and hence there is no point in stating that this interface is non-public. Document this interface and remove the obsolete comment. * manual/memory.texi (M_ARENA_TEST): Add documentation. (M_ARENA_MAX): Likewise. * malloc/malloc.c: Remove obsolete comment.
* malloc: Manual part of conversion to __libc_lockFlorian Weimer2016-09-212-4/+4
| | | | | This removes the old mutex_t-related definitions from malloc-machine.h, too.
* Add tests-static to tests in malloc/MakefileSiddhesh Poyarekar2016-09-101-2/+1
| | | | | | | | | | This is a trivial change to add the static tests only to tests-static and then adding all of tests-static to the tests target to make it look consistent with some other Makefiles. This avoids having to duplicate the test names across the two make targets. * malloc/Makefile (tests): Remove individual static test names and just add all of tests-static.
* malloc: Automated part of conversion to __libc_lockFlorian Weimer2016-09-063-60/+60

* malloc: Simplify static malloc interposition [BZ #20432]Florian Weimer2016-08-2610-1/+648
| | | | | | | | Existing interposed mallocs do not define the glibc-internal fork callbacks (and they should not), so statically interposed mallocs lead to link failures because the strong reference from fork pulls in glibc's malloc, resulting in multiple definitions of malloc-related symbols.
* elf: dl-minimal malloc needs to respect fundamental alignmentFlorian Weimer2016-08-032-63/+53
| | | | | | | | | | | | | | The dynamic linker currently uses __libc_memalign for TLS-related allocations. The goal is to switch to malloc instead. If the minimal malloc follows the ABI fundamental alignment, we can assume that malloc provides this alignment, and thus skip explicit alignment in a few cases as an optimization. It was requested on libc-alpha that MALLOC_ALIGNMENT should be used, although this results in wasted space if MALLOC_ALIGNMENT is larger than the fundamental alignment. (The dynamic linker cannot assume that the non-minimal malloc will provide an alignment of MALLOC_ALIGNMENT; the ABI provides _Alignof (max_align_t) only.)
* malloc: Run tests without calling mallopt [BZ #19469]Florian Weimer2016-08-021-0/+4
| | | | | | The compiled tests no longer refer to the mallopt symbol from their main functions. (Some tests still call mallopt explicitly, which is fine.)
* malloc: Preserve arena free list/thread count invariant [BZ #20370]Florian Weimer2016-08-021-5/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | It is necessary to preserve the invariant that if an arena is on the free list, it has thread attach count zero. Otherwise, when arena_thread_freeres sees the zero attach count, it will add it, and without the invariant, an arena could get pushed to the list twice, resulting in a cycle. One possible execution trace looks like this: Thread 1 examines free list and observes it as empty. Thread 2 exits and adds its arena to the free list, with attached_threads == 0). Thread 1 selects this arena in reused_arena (not from the free list). Thread 1 increments attached_threads and attaches itself. (The arena remains on the free list.) Thread 1 exits, decrements attached_threads, and adds the arena to the free list. The final step creates a cycle in the usual way (by overwriting the next_free member with the former list head, while there is another list item pointing to the arena structure). tst-malloc-thread-exit exhibits this issue, but it was only visible with a debugger because the incorrect fix in bug 19243 removed the assert from get_free_list.
* Bump up tst-malloc-thread-fail timeout from 20 to 30sChris Metcalf2016-07-051-1/+1
| | | | | | Right now tilegx is right on the verge of timeout when it runs, so adding a bit of headroom seems like the right thing; we see failures when running tests in parallel.
* test-skeleton.c: Add write_message functionFlorian Weimer2016-06-231-11/+3
|
* malloc: Avoid premature fallback to mmap [BZ #20284]Florian Weimer2016-06-211-6/+4
| | | | | | | Before this change, the while loop in reused_arena which avoids returning a corrupt arena would never execute its body if the selected arena were not corrupt. As a result, result == begin after the loop, and the function returns NULL, triggering fallback to mmap.
* Revert __malloc_initialize_hook symbol poisoningFlorian Weimer2016-06-205-23/+6
| | | | | | It turns out the Emacs-internal malloc implementation uses __malloc_* symbols. If glibc poisons them in <stdc-pre.h>, Emacs will no longer compile.
* malloc_usable_size: Use correct size for dumped fake mapped chunksFlorian Weimer2016-06-111-1/+6
| | | | | | The adjustment for the size computation in commit 1e8a8875d69e36d2890b223ffe8853a8ff0c9512 is needed in malloc_usable_size, too.
* malloc: Remove __malloc_initialize_hook from the API [BZ #19564]Florian Weimer2016-06-106-8/+60
| | | | | | | __malloc_initialize_hook is interposed by application code, so the usual approach to define a compatibility symbol does not work. This commit adds a new mechanism based on #pragma GCC poison in <stdc-predef.h>.
* malloc: Correct size computation in realloc for dumped fake mmapped chunksFlorian Weimer2016-06-081-4/+8
| | | | | | | | For regular mmapped chunks there are two size fields (hence a reduction by 2 * SIZE_SZ bytes), but for fake chunks, we only have one size field, so we need to subtract SIZE_SZ bytes. This was initially reported as Emacs bug 23726.
* malloc: Correct malloc alignment on 32-bit architectures [BZ #6527]Florian Weimer2016-05-242-15/+3
| | | | | | | | | | | | | | | | After the heap rewriting added in commit 4cf6c72fd2a482e7499c29162349810029632c3f (malloc: Rewrite dumped heap for compatibility in __malloc_set_state), we can change malloc alignment for new allocations because the alignment of old allocations no longer matters. We need to increase the malloc state version number, so that binaries containing dumped heaps of the new layout will not try to run on previous versions of glibc, resulting in obscure crashes. This commit addresses a failure of tst-malloc-thread-fail on the affected architectures (32-bit ppc and mips) because the test checks pointer alignment.
* tst-mallocfork2: Fix race condition, use fewer resourcesFlorian Weimer2016-05-131-1/+7
| | | | | | | | | | | | | | | | The first SIGUSR1 signal could arrive when sigusr1_sender_pid was still 0. As a result, kill would send SIGSTOP to the entire process group. This would cause the test to hang before printing any output. This commit also adds a sched_yield to the signal source, so that it does not flood the parent process with signals it has never a chance to handle. Even with these changes, tst-mallocfork2 still fails reliably after the fix in commit commit 56290d6e762c1194547e73ff0b948cd79d3a1e03 (Increase fork signal safety for single-threaded processes) is backed out.
* malloc: Rewrite dumped heap for compatibility in __malloc_set_stateFlorian Weimer2016-05-132-109/+96
| | | | | | | | | | | | | | | | | This will allow us to change many aspects of the malloc implementation while preserving compatibility with existing Emacs binaries. As a result, existing Emacs binaries will have a larger RSS, and Emacs needs a few more milliseconds to start. This overhead is specific to Emacs (and will go away once Emacs switches to its internal malloc). The new checks to make free and realloc compatible with the dumped heap are confined to the mmap paths, which are already quite slow due to the munmap overhead. This commit weakens some security checks, but only for heap pointers in the dumped main arena. By default, this area is empty, so those checks are as effective as before.
* Increase fork signal safety for single-threaded processes [BZ #19703]Florian Weimer2016-05-122-1/+214
| | | | | | | | | This provides a band-aid and addresses the scenario where fork is called from a signal handler while the process is in the malloc subsystem (or has acquired the libio list lock). It does not address the general issue of async-signal-safety of fork; multi-threaded processes are not covered, and some glibc subsystems have fork handlers which are not async-signal-safe.
* malloc: Adjust header file guard in malloc-internal.hFlorian Weimer2016-05-041-3/+3

* malloc: Add missing internal_function attributes on function definitionsFlorian Weimer2016-04-141-0/+3
| | | | Fixes build on i386 after commit 29d794863cd6e03115d3670707cc873a9965ba92.
* malloc: Remove malloc hooks from fork handlerFlorian Weimer2016-04-142-119/+8
| | | | | | | The fork handler now runs so late that there is no risk anymore that other fork handlers in the same thread use malloc, so it is no longer necessary to install malloc hooks which made a subset of malloc functionality available to the thread that called fork.
* malloc: Run fork handler as late as possible [BZ #19431]Florian Weimer2016-04-145-42/+272
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, a thread M invoking fork would acquire locks in this order: (M1) malloc arena locks (in the registered fork handler) (M2) libio list lock A thread F invoking flush (NULL) would acquire locks in this order: (F1) libio list lock (F2) individual _IO_FILE locks A thread G running getdelim would use this order: (G1) _IO_FILE lock (G2) malloc arena lock After executing (M1), (F1), (G1), none of the threads can make progress. This commit changes the fork lock order to: (M'1) libio list lock (M'2) malloc arena locks It explicitly encodes the lock order in the implementations of fork, and does not rely on the registration order, thus avoiding the deadlock.

* malloc: Test various special cases related to allocation failuresFlorian Weimer2015-12-292-1/+446
| | | | | | | | | | | | | | | | This test case exercises unusual code paths in allocation functions, related to allocation failures. Specifically, the test can reveal the following bugs: (a) calloc returns non-zero memory on fallback to sysmalloc. (b) calloc can self-deadlock because it fails to release the arena lock on certain allocation failures. (c) pvalloc can dereference a NULL arena pointer. (a) and (b) appear specific to a faulty downstream backport. (c) was fixed as part of commit 10ad46bc6526edc5c7afcc57112da96917ff3629. The test for (a) was inspired by a reproducer supplied by Jeff Layton.

* malloc: Fix attached thread reference count handling [BZ #19243]Florian Weimer2015-12-163-5/+228
| | | | | | | | | | | | | | | | reused_arena can increase the attached thread count of arenas on the free list. This means that the assertion that the reference count is zero is incorrect. In this case, the reference count initialization is incorrect as well and could cause arenas to be put on the free list too early (while they still have attached threads). * malloc/arena.c (get_free_list): Remove assert and adjust reference count handling.

* Convert a few more function definitions to prototype style.Joseph Myers2015-10-211-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts a few more function definitions in glibc from old-style K&R to prototype style. This is sufficient to build and test on x86_64 and x86 with -Wold-style-definition (I'll test on some more architectures before proposing the actual addition of -Wold-style-definition). Tested for x86_64 and x86 with -Wold-style-definition in use (testsuite - this patch affects files containing assertions). * io/fts.c (fts_open): Convert to prototype-style function definition. * malloc/mcheck.c (mcheck): Likewise.

* Convert 113 more function definitions to prototype style (files with ↵Joseph Myers2015-10-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | assertions). This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.
