2015-10-05libc: fix setting return value and errno in fallocate()Yuriy Kolerov
fallocate system call must return 0 on success. On error, -1 is returned and errno is set to indicate the error. However there is an error in fallocate which is fixed by this patch - it does not set errno and returns invalid value on error (it returns error code instead of -1). This error is detected in LTP's test kernel/syscalls/fallocate02: ----------->8---------- fallocate(..., 1, 0, 1024) failed, expected errno:9: TEST_ERRNO=0 fallocate(..., 1, -1024, 1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 1024, -1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 12288, 0) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 12288, -1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, -24576, 1024) failed, expected errno:22: TEST_ERRNO=0 ----------->8---------- Signed-off-by: Yuriy Kolerov <yuriy.kolerov@synopsys.com>
2014-09-09libc: add fallocate() and fallocate64()Anthony G. Basile
We add the Linux-specific function fallocate() which allows the user to directly manipulate allocate space for a file. fallocate() can operate in different modes, but the default mode is equivalent to posix_fallocate() which is specified in POSIX.1. Recent releases of e2fsprogs 1.42.11 and above expect fallocate64() to be available. Signed-off-by: Anthony G.
