We want newer versions of libzfs_core to run against an existing
zfs kernel module (i.e. a deferred reboot or module reload after
an update).
Programmatically document, via a zfs_ioc_key_t, the valid arguments
for the ioc commands that rely on nvpair input arguments (i.e. non
legacy commands from libzfs_core). Automatically verify the expected
pairs before dispatching a command.
This initial phase focuses on the non-legacy ioctls. A follow-on
change can address the legacy ioctl input from the zfs_cmd_t.
The zfs_ioc_key_t for zfs_keys_channel_program looks like:
static const zfs_ioc_key_t zfs_keys_channel_program[] = {
{"program", DATA_TYPE_STRING, 0},
{"arg", DATA_TYPE_UNKNOWN, 0},
{"sync", DATA_TYPE_BOOLEAN_VALUE, ZK_OPTIONAL},
{"instrlimit", DATA_TYPE_UINT64, ZK_OPTIONAL},
{"memlimit", DATA_TYPE_UINT64, ZK_OPTIONAL},
};
Introduce four input errors to identify specific input failures
(in addition to generic argument value errors like EINVAL, ERANGE,
EBADF, and E2BIG).
ZFS_ERR_IOC_CMD_UNAVAIL the ioctl number is not supported by kernel
ZFS_ERR_IOC_ARG_UNAVAIL an input argument is not supported by kernel
ZFS_ERR_IOC_ARG_REQUIRED a required input argument is missing
ZFS_ERR_IOC_ARG_BADTYPE an input argument has an invalid type
