Add basic zfs ioc input nvpair validation 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 Reviewed-by: Matthew Ahrens <mahrens@delphix.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Don Brady <don.brady@delphix.com> Closes #7780 2018-09-02 22:14:01 +03:00			`include $(top_srcdir)/config/Rules.am`

Check for strlcat and strlcpy This partially reverts commit 8005ca4 by moving the strlcat() and strlcpy() compatibility implementations back to their original location. In addition, these two functions were added to the AC_CHECK_FUNCS macro. When these functions are available from the C library, HAVE_STRLCAT and HAVE_STRLCPY will be defined and library version used. Otherwise the compatibility version is built.
