Hi,

This patch set fixes two bugs of splice_write in the virtio-console driver.

[BUG1] Although pipe->nrbufs is empty, the driver tries to do splice_write.
        => This induces oops in sg_init_table().

[BUG2] No lock for competition of splice_write.
        => This induces oops in splice_from_pipe_feed() by bug of any user
           application.

These reports are written in each patch.

Changes in V2:
- Fix a locking problem for error

Thanks!

Thank you for reviewing this patch set.

For the patches to be picked up in the stable trees, you need to
include CC: [off-list ref] in the sign-off area of the
patches, just cc'ing in the patch posting doesn't help.  See
Documentation/stable_kernel_rules.txt.

Can you submit a v3 with that change, and also add my reviewed-by
line?

Sure. I'll add stable@ line, your reviewed-by line, and Masami's
reviewed-by line in sign-off area for each patch.

Thanks,
Yoshihiro YUNOMAE
