vfs: Return -ENXIO for negative SEEK_HOLE / SEEK_DATA offsets

2017-10-05T07:41:45Z

commit fc46820b27a2d9a46f7e90c9ceb4a64a1bc5fab8 upstream. In generic_file_llseek_size, return -ENXIO for negative offsets as well as offsets beyond EOF. This affects filesystems which don't implement SEEK_HOLE / SEEK_DATA internally, possibly because they don't support holes. Fixes xfstest generic/448.

new_sync_write(): discard ->ki_pos unless the return value is positive

2015-04-12T02:29:46Z

That allows ->write_iter() instances much more convenient life wrt iocb->ki_pos (and fixes several filesystems with borderline POSIX violations when zero-length write succeeds and changes the current position). Signed-off-by: Al Viro

->aio_read and ->aio_write removed

kill do_sync_read/do_sync_write

2015-04-12T02:29:42Z

all remaining instances of aio_{read,write} (all 4 of them) have explicit ->read and ->write resp.; do_sync_read/do_sync_write is never called by __vfs_read/__vfs_write anymore and no other users had been left. Signed-off-by: Al Viro

make new_sync_{read,write}() static

2015-04-12T02:29:40Z

All places outside of core VFS that checked ->read and ->write for being NULL or called the methods directly are gone now, so NULL {read,write} with non-NULL {read,write}_iter will do the right thing in all cases. Signed-off-by: Al Viro

switch {compat_,}do_readv_writev() to {compat_,}import_iovec()

Signed-off-by: Al Viro

lift iov_iter into {compat_,}do_readv_writev()

2015-04-12T02:26:45Z

get it closer to matching {compat_,}rw_copy_check_uvector(). Signed-off-by: Al Viro

fs: move struct kiocb to fs.h

2015-03-26T00:28:11Z

struct kiocb now is a generic I/O container, so move it to fs.h. Also do a #include diet for aio.h while we're at it. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro
