35 | * ZFS ioctls. | |
36 | * | |
37 | * This file handles the ioctls to /dev/zfs, used for configuring ZFS storage | |
38 | * pools and filesystems, e.g. with /sbin/zfs and /sbin/zpool. | |
39 | * | |
40 | * There are two ways that we handle ioctls: the legacy way where almost | |
41 | * all of the logic is in the ioctl callback, and the new way where most | |
42 | * of the marshalling is handled in the common entry point, zfsdev_ioctl(). | |
43 | * | |
44 | * Non-legacy ioctls should be registered by calling | |
45 | * zfs_ioctl_register() from zfs_ioctl_init(). The ioctl is invoked | |
46 | * from userland by lzc_ioctl(). | |
47 | * | |
48 | * The registration arguments are as follows: | |
49 | * | |
50 | * const char *name | |
51 | * The name of the ioctl. This is used for history logging. If the | |
52 | * ioctl returns successfully (the callback returns 0), and allow_log | |
53 | * is true, then a history log entry will be recorded with the input & | |
54 | * output nvlists. The log entry can be printed with "zpool history -i". | |
55 | * | |
56 | * zfs_ioc_t ioc | |
57 | * The ioctl request number, which userland will pass to ioctl(2). | |
58 | * The ioctl numbers can change from release to release, because | |
59 | * the caller (libzfs) must be matched to the kernel. | |
60 | * | |
61 | * zfs_secpolicy_func_t *secpolicy | |
62 | * This function will be called before the zfs_ioc_func_t, to | |
63 | * determine if this operation is permitted. It should return EPERM | |
64 | * on failure, and 0 on success. Checks include determining if the | |
65 | * dataset is visible in this zone, and if the user has either all | |
66 | * zfs privileges in the zone (SYS_MOUNT), or has been granted permission | |
67 | * to do this operation on this dataset with "zfs allow". | |
68 | * | |
69 | * zfs_ioc_namecheck_t namecheck | |
70 | * This specifies what to expect in the zfs_cmd_t:zc_name -- a pool | |
71 | * name, a dataset name, or nothing. If the name is not well-formed, | |
72 | * the ioctl will fail and the callback will not be called. | |
73 | * Therefore, the callback can assume that the name is well-formed | |
74 | * (e.g. is null-terminated, doesn't have more than one '@' character, | |
75 | * doesn't have invalid characters). | |
76 | * | |
77 | * zfs_ioc_poolcheck_t pool_check | |
78 | * This specifies requirements on the pool state. If the pool does | |
79 | * not meet them (is suspended or is readonly), the ioctl will fail | |
80 | * and the callback will not be called. If any checks are specified | |
81 | * (i.e. it is not POOL_CHECK_NONE), namecheck must not be NO_NAME. | |
82 | * Multiple checks can be or-ed together (e.g. POOL_CHECK_SUSPENDED | | |
83 | * POOL_CHECK_READONLY). | |
84 | * | |
85 | * boolean_t smush_outnvlist | |
86 | * If smush_outnvlist is true, then the output is presumed to be a | |
87 | * list of errors, and it will be "smushed" down to fit into the | |
88 | * caller's buffer, by removing some entries and replacing them with a | |
89 | * single "N_MORE_ERRORS" entry indicating how many were removed. See | |
90 | * nvlist_smush() for details. If smush_outnvlist is false, and the | |
91 | * outnvlist does not fit into the userland-provided buffer, then the | |
92 | * ioctl will fail with ENOMEM. | |
93 | * | |
94 | * zfs_ioc_func_t *func | |
95 | * The callback function that will perform the operation. | |
96 | * | |
97 | * The callback should return 0 on success, or an error number on | |
98 | * failure. If the function fails, the userland ioctl will return -1, | |
99 | * and errno will be set to the callback's return value. The callback | |
100 | * will be called with the following arguments: | |
101 | * | |
102 | * const char *name | |
103 | * The name of the pool or dataset to operate on, from | |
104 | * zfs_cmd_t:zc_name. The 'namecheck' argument specifies the | |
105 | * expected type (pool, dataset, or none). | |
106 | * | |
107 | * nvlist_t *innvl | |
108 | * The input nvlist, deserialized from zfs_cmd_t:zc_nvlist_src. Or | |
109 | * NULL if no input nvlist was provided. Changes to this nvlist are | |
110 | * ignored. If the input nvlist could not be deserialized, the | |
111 | * ioctl will fail and the callback will not be called. | |
112 | * | |
113 | * nvlist_t *outnvl | |
114 | * The output nvlist, initially empty. The callback can fill it in, | |
115 | * and it will be returned to userland by serializing it into | |
116 | * zfs_cmd_t:zc_nvlist_dst. If it is non-empty, and serialization | |
117 | * fails (e.g. because the caller didn't supply a large enough | |
118 | * buffer), then the overall ioctl will fail. See the | |
119 | * 'smush_nvlist' argument above for additional behaviors. | |
120 | * | |
121 | * There are two typical uses of the output nvlist: | |
122 | * - To return state, e.g. property values. In this case, | |
123 | * smush_outnvlist should be false. If the buffer was not large | |
124 | * enough, the caller will reallocate a larger buffer and try | |
125 | * the ioctl again. | |
126 | * | |
127 | * - To return multiple errors from an ioctl which makes on-disk | |
128 | * changes. In this case, smush_outnvlist should be true. | |
129 | * Ioctls which make on-disk modifications should generally not | |
130 | * use the outnvl if they succeed, because the caller can not | |
131 | * distinguish between the operation failing, and | |
132 | * deserialization failing. | |
