Bart Van Assche 420405ecde configfs: fix the read and write iterators ... Commit 7fe1e79b59 ("configfs: implement the .read_iter and .write_iter methods") changed the simple_read_from_buffer() calls into copy_to_iter() calls and the simple_write_to_buffer() calls into copy_from_iter() calls. The simple*buffer() methods update the file offset (*ppos) but the read and write iterators not yet. Make the read and write iterators update the file offset (iocb->ki_pos). This patch has been tested as follows: # modprobe target_core_user # dd if=/sys/kernel/config/target/dbroot bs=1 /var/target 12+0 records in 12+0 records out 12 bytes copied, 9.5539e-05 s, 126 kB/s # cd /sys/kernel/config/acpi/table # mkdir test # cd test # dmesg -c >/dev/null; printf 'SSDT\x8\0\0\0abcdefghijklmnopqrstuvwxyz' | dd of=aml bs=1; dmesg -c 34+0 records in 34+0 records out 34 bytes copied, 0.010627 s, 3.2 kB/s [ 261.056551] ACPI configfs: invalid table length Reported-by: Yanko Kaneti <yaneti@declera.com> Cc: Yanko Kaneti <yaneti@declera.com> Fixes: 7fe1e79b59 ("configfs: implement the .read_iter and .write_iter methods") Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Christoph Hellwig <hch@lst.de>		2021-07-13 20:56:24 +02:00
