Currently 32 bit application gets ENOTTY when it calls compat_ioctl with NVME_IOCTL_SUBMIT_IO in 64 bit kernel. The cause is that the results of sizeof(struct nvme_user_io), which is used to define NVME_IOCTL_SUBMIT_IO, are not same between 32 bit compiler and 64 bit compiler. * 32 bit: the result of sizeof nvme_user_io is 44. * 64 bit: the result of sizeof nvme_user_io is 48. 64 bit compiler seems to add 32 bit padding for multiple of 8 bytes. This patch adds a compat_ioctl handler. The handler replaces NVME_IOCTL_SUBMIT_IO32 with NVME_IOCTL_SUBMIT_IO in case 32 bit application calls compat_ioctl for submit in 64 bit kernel. Then, it calls nvme_ioctl as usual. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Masahiro Yamada (KIOXIA) <masahiro31.yamada@kioxia.com> Signed-off-by: Keith Busch <kbusch@kernel.org> |
