2011-07-08(memalign_check): No need to use checked_request2size.Ulrich Drepper1-3/+1
2011-06-28Fix quoting in some installed shell scriptsUlrich Drepper1-1/+1
2011-06-28Remove the --experimental-malloc optionUlrich Drepper1-3/+1
It's well tested, make it the default.
2011-05-29Mark malloc hook variables as deprecatedUlrich Drepper1-6/+14
2011-05-29Perhaps the real definition of __MALLOC_HOOK_VOLATILE should be addedUlrich Drepper1-1/+1
2011-05-29Missed one malloc hook variableUlrich Drepper1-1/+1
2011-05-29Declare malloc hook variables as volatile.Ulrich Drepper1-38/+45
2011-05-28Unify messagesUlrich Drepper1-2/+2
Some shell scripts unnecessarily used different formats for some messages. Unify them to reduce the work of translators.
2011-05-16Avoid potential deadlock in mtraceUlrich Drepper1-23/+41
The _dl_addr function might have to call malloc which would lead to a deadlock. Avoid by calling _dl_addr early.
2011-05-16Remove USE_MTRACE_FILE support from mtraceUlrich Drepper1-17/+2
2011-04-22Remove doubled words.Jim Meyering1-2/+2
2011-01-17Update copyright year.Ulrich Drepper2-4/+4
2010-12-25Use fastbin macro everywhere.Ulrich Drepper1-1/+1
2010-10-24Fix perturbing in malloc on free.Ulrich Drepper1-2/+2
2010-10-03Handle large requests.Ulrich Drepper1-1/+21
2010-08-16Replace divide and multiply with mask in sYSTRImAnton Blanchard2-6/+6
2010-05-06Fix race in free sanity check.Ulrich Drepper1-6/+9
2010-04-14Remove unintended change.Ulrich Drepper1-4/+0
2010-04-14Optimie x86-64 SSE4 memcmp for unaligned data.H.J. Lu1-0/+4
2010-04-08Fix possibly uninitilized variable handling.Ulrich Drepper1-0/+1
If malloc errors are ignored (which say aren't by default and never should be) malloc in the old, slow form might use an uninitialized variable.
2010-04-03One more sanity check in free.Ulrich Drepper1-1/+14
2010-04-03Fix set_max_fast in malloc.Ulrich Drepper1-1/+2

2010-02-24Fix typos I added in malloc.cUlrich Drepper1-2/+2
2010-02-24Fix assertion in palloc and pvalloc as well.Petr Baudis1-7/+9
2010-02-10Undo unintended maloc change.Ulrich Drepper1-15/+2
2010-02-09Avoid PLT call to fegetenv on s390Andreas Schwab1-2/+15
2010-01-14Fix malloc_info without prioor allocations.Ulrich Drepper1-17/+24
2009-11-06Fix spelling in memusagestat.cHolger Hans Peter Freyther1-1/+1
2009-11-01Restore locking in free_check.Ulrich Drepper1-17/+20
This code is only used when MALLOC_CHECK_ is used. Then some bogus crashes and/or assert could result from the locking changes. The code ain't fast.
2009-10-29Fix typos in format strings of malloc_info.John Sullivan1-2/+2
2009-10-29Fix repairing of memusage trace files.Ulrich Drepper1-13/+19
2009-10-29Fix wrap-around in memusage.Andreas Schwab1-4/+5
2009-08-31Add local assert function to avoid problems with memory allocation inUlrich Drepper1-439/+461
the real one.
2009-07-31Fix obstack* on i?86Jakub Jelinek1-0/+1
obstack calls several callbacks, so on i?86 it'd better be compiled without -mpreferred-stack-boundary=2, otherwise the callbacks are called with misaligned stack.
2009-07-16Fix race in corruption check.Ulrich Drepper1-2/+23
With atomic fastbins the checks performed can race with concurrent modifications of the arena. If we detect a problem re-do the test after getting the lock.
2009-07-16Use rel semantics of cas instead of acq semantics with full barrier before ↵Jakub Jelinek1-2/+1
it in _int_free The following patch fixes catomic_compare_and_exchange_*_rel definitions (which were never used and weren't correct) and uses catomic_compare_and_exchange_val_rel in _int_free. Comparing to the pre-2009-07-02 --enable-experimental-malloc state the generated code should be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use lwsync instead of isync barrier.
2009-07-02Fix possible race when freeing object in fast bin list.Ulrich Drepper1-0/+1
2009-06-18Add some more tests to malloc to detect corruptions.Ulrich Drepper1-2/+27
