2013-02-20fstatfs64: Prefer fstatfs64 system call instead of __libc_fstatfsMarkos Chandras
Using __libc_fstatfs for fstatfs64 adds a small delay as it needs to use a 32-bit data structure to get the file info and them pass them to the 64-bit data structure which was given as a fstatfs64 argument. Using the system call directly should make the entire process much faster. Also fix the arguments for fstatfs64. It takes three arguments (see fs/fstatfs.c in Linux kernel sources) so despite what the manpage says, the size of the buffer needs to be passed as the second argument Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2013-02-20fstatfs: Add __libc_fstatfs wrapperMarkos Chandras
New architectures don't have fstatfs anymore, so we use a wrapper for __libc_fstatfs which will use fstatfs64 internally. The interface however needs to remain the same (i.e accepting a struct statfs as a second argument) for backwards compatibility Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2013-02-20libc/statfs64: Skip conversion code for new architecturesMarkos Chandras
Fixes the following tests in LTP statfs02_64 ( test case #5 ) The purpose of this test is to pass an invalid pointer to the statfs64 syscall and check if the kernel returns EFAULT or not. However, uClibc creates a new statfs struct which is then passed to the kernel. As a result of which, the kernel returns 0 because the newly created statfs structure is valid. But, when copying the contens of the new pointer to the old userspace one, the uClibc segfauls because the old pointer is invalid. Old architectures are doomed to suffer by this problem but new architectures can use the statfs64 syscall directly so that the userspace pointer is passed directly to the kernel and get the correct errno at the end.
