2016-01-10order of special checks mattersWaldemar Brodkorb
The order of special checks seems critical for some applications. Xorg 1.18.0 fails to start with XNFreallocarray error. Took me some time to run with MALLOC_DEBUG=2 to find out. MALLOC_STANDARD is not affected.
2016-01-06pthread_atfork handlers not removed during dlcloseWaldemar Brodkorb
Invoke pthread_atfork handler cleanup when removing the associated DSO... If a program loads a DSO (dlopen) that sets up a pthread_atfork handler(s), and then subsequently closes the DSO, the handler(s) are left in place. If fork() is subsequently called, the handlers are invoked even though the DSO has been removed causing crashes or unpredictable code execution. This is because the code in __cxa_finalize(atexit.c)to invoke the unregister_atfork() routine is ifdef'd out with the comment that it hasn't been "looked into this yet...".

2015-12-17libc/stdlib: canonicalize_file_name() memory leakWojciech Nizinski
Uclibc's canonicalize_file_name() is allocating temprary buffer of 4kB (PATH_MAX), and passing it to realpath() as second argument. Function is not checking if realpath() fails and memory is lost.

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.

2014-12-15mkostemp: fix implementationAnthony G. Basile
mkostemp(char *template, int flags) generates a unique temporary filename from a template. The flags parameter accepts three of the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The current implementation of mkostemp(3) does not respect the flags and in fact confuses the flags with the file mode which should always be S_IRUSR | S_IWUSR. This patch corrects this issue.

2012-11-18drop support for pre ISO-C compilersMike Frysinger
This drops __signed, __volatile, and __const. Only the latter was used in the code base, and for uClibc, not consistently. Much of the code used plain "const" which meant "__const" was useless.

Change uint32_t to u_int32_t and uint8_t to u_int8_t, removing completely the dependency on stdint.h. Based on patch by Timo Teraes <timo.teras@iki.fi>. His comment: This also fixes a major bug that stdlib.h includes stdint.h. Things might go very wrong because stdint.h has conditional defines and if stdlib.h is included before #define's for stdint.h we end up missing things and breaking builds (e.g. openjdk).
