My reading > of man getcwd is that the call of nss is legit (as a glibc extension). > Maybe this is a glibc bug? Quoting man getcwd: As an extension to the POSIX.1-2001 standard, glibc's getcwd() allocates the buffer dynamically using malloc(3) if buf is NULL. In this case, the allocated buffer has the length size unless size is zero, when buf is allocated as big as necessary But that's from manpages-dev. The documentation from glibc itself says: The GNU C Library version of this function also permits you to specify a null pointer for the buffer argument. Then getcwd allocates a buffer automatically, as with malloc (see Unconstrained Allocation). If the size is greater than zero, then the buffer is that large; otherwise, the buffer is as large as necessary to hold the result. Which is essentially the same thing. The unistd.h header itself says: In GNU, if BUF is NULL, an array is allocated with `malloc'; the array is SIZE bytes long, unless SIZE == 0, in which case it is as big as necessary. This doesn't fit with the use of __attribute__((access(write_only(1, 2 IMO. Mike
