2018-01-31malloc: add malloc_usable_size()Waldemar Brodkorb
2017-11-03malloc-standard/malloc.h: use getpagesizeYitai Schwartz
sysconf creates a lot of code dependencies. getpagesize dosen't. staticly linked code that calls malloc is now much smaller. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>
2016-12-20remove __MALLOC_GLIBC_COMPAT__ optionWaldemar Brodkorb
This option is enabled for a long time and I see no useful case where we should be incompatible to glibc here.
2016-11-27add aligned_alloc required for latest gcc libstdc++Waldemar Brodkorb
2016-05-18remove linuxthreads.new, rename linuxthreads.oldWaldemar Brodkorb
Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT. LINUXTHREADS_OLD -> UCLIBC_HAS_LINUXTHREADS

This fix commit 76dfc7ce8c "Some requested additional malloc entry points" from 2004's Signed-off-by: Leonid Lisovskiy <lly.dev@gmail.com> Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

Closes bugzilla #4586 Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2015-03-18malloc: checked_request2size failure deadlocksZhiqiang Zhang
For some rarely cases(almost App bugs), calling malloc with a very largre size, checked_request2size check will fail,set ENOMEM, and return 0 to caller. But this will let __malloc_lock futex locked and owned by the caller. In multithread circumstance, other thread calling malloc/calloc will NOT succeed and get locked.

2013-02-05mman: rename MAP_UNINITIALIZE to MAP_UNINITIALIZEDBernhard Reutner-Fischer
The name was changed to include a trailing 'D' when it went into the kernel. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2009-11-23nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger
Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use it to get real uninitialized memory on no-mmu systems. This avoids a lot of normally useless overhead involved in zeroing out all of the memory (sometimes multiple times). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.
