2015-01-07	setenv fix memory leak when setting large, duplicate string (BZ #17658)	Eric Biggers
	glibc maintains a binary tree of environment strings it malloc()ed itself. However, it's possible for it to malloc() a string, then find that an identical string is already in the tree. In this case, the memory is leaked and is not freed if the application later calls __libc_freeres(). Fix this by freeing 'new_value' when it's unneeded. Test case: #include <stdlib.h> #include <string.h> int main() { char *p = calloc(100000, 1); memset(p, 'A', 99999); setenv("TESTVAR", p, 1); setenv("TESTVAR", p, 1); free(p); } Leak that was reported by valgrind: 100,008 bytes in 1 blocks are definitely lost in loss record 1 of 1 at 0x4C29F90: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) by 0x4E6B3D4: __add_to_environ (setenv.c:176) by 0x4C31B8F: setenv (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) by 0x400642: main (in /mnt/tmpfs/a.out)
