The ioctl is invoked 444445fffbSMatthew Ahrens * from userland by lzc_ioctl(). 454445fffbSMatthew Ahrens * 464445fffbSMatthew Ahrens * The registration arguments are as follows: 474445fffbSMatthew Ahrens * 484445fffbSMatthew Ahrens * const char *name 494445fffbSMatthew Ahrens * The name of the ioctl. This is used for history logging. If the 504445fffbSMatthew Ahrens * ioctl returns successfully (the callback returns 0), and allow_log 514445fffbSMatthew Ahrens * is true, then a history log entry will be recorded with the input & 524445fffbSMatthew Ahrens * output nvlists. The log entry can be printed with "zpool history -i". 534445fffbSMatthew Ahrens * 544445fffbSMatthew Ahrens * zfs_ioc_t ioc 554445fffbSMatthew Ahrens * The ioctl request number, which userland will pass to ioctl(2). 564445fffbSMatthew Ahrens * The ioctl numbers can change from release to release, because 574445fffbSMatthew Ahrens * the caller (libzfs) must be matched to the kernel. 584445fffbSMatthew Ahrens * 594445fffbSMatthew Ahrens * zfs_secpolicy_func_t *secpolicy 604445fffbSMatthew Ahrens * This function will be called before the zfs_ioc_func_t, to 614445fffbSMatthew Ahrens * determine if this operation is permitted. It should return EPERM 624445fffbSMatthew Ahrens * on failure, and 0 on success. Checks include determining if the 634445fffbSMatthew Ahrens * dataset is visible in this zone, and if the user has either all 644445fffbSMatthew Ahrens * zfs privileges in the zone (SYS_MOUNT), or has been granted permission 654445fffbSMatthew Ahrens * to do this operation on this dataset with "zfs allow". 664445fffbSMatthew Ahrens * 674445fffbSMatthew Ahrens * zfs_ioc_namecheck_t namecheck 684445fffbSMatthew Ahrens * This specifies what to expect in the zfs_cmd_t:zc_name -- a pool 694445fffbSMatthew Ahrens * name, a dataset name, or nothing. If the name is not well-formed, 704445fffbSMatthew Ahrens * the ioctl will fail and the callback will not be called. 714445fffbSMatthew Ahrens * Therefore, the callback can assume that the name is well-formed 724445fffbSMatthew Ahrens * (e.g. is null-terminated, doesn't have more than one '@' character, 734445fffbSMatthew Ahrens * doesn't have invalid characters). 744445fffbSMatthew Ahrens * 754445fffbSMatthew Ahrens * zfs_ioc_poolcheck_t pool_check 764445fffbSMatthew Ahrens * This specifies requirements on the pool state. If the pool does 774445fffbSMatthew Ahrens * not meet them (is suspended or is readonly), the ioctl will fail 784445fffbSMatthew Ahrens * and the callback will not be called. If any checks are specified 794445fffbSMatthew Ahrens * (i.e. it is not POOL_CHECK_NONE), namecheck must not be NO_NAME. 804445fffbSMatthew Ahrens * Multiple checks can be or-ed together (e.g. POOL_CHECK_SUSPENDED | 814445fffbSMatthew Ahrens * POOL_CHECK_READONLY). 824445fffbSMatthew Ahrens * 834445fffbSMatthew Ahrens * boolean_t smush_outnvlist 844445fffbSMatthew Ahrens * If smush_outnvlist is true, then the output is presumed to be a 854445fffbSMatthew Ahrens * list of errors, and it will be "smushed" down to fit into the 864445fffbSMatthew Ahrens * caller's buffer, by removing some entries and replacing them with a 874445fffbSMatthew Ahrens * single "N_MORE_ERRORS" entry indicating how many were removed. See 884445fffbSMatthew Ahrens * nvlist_smush() for details. If smush_outnvlist is false, and the 894445fffbSMatthew Ahrens * outnvlist does not fit into the userland-provided buffer, then the 904445fffbSMatthew Ahrens * ioctl will fail with ENOMEM. 914445fffbSMatthew Ahrens * 924445fffbSMatthew Ahrens * zfs_ioc_func_t *func 934445fffbSMatthew Ahrens * The callback function that will perform the operation. 944445fffbSMatthew Ahrens * 954445fffbSMatthew Ahrens * The callback should return 0 on success, or an error number on 964445fffbSMatthew Ahrens * failure. If the function fails, the userland ioctl will return -1, 974445fffbSMatthew Ahrens * and errno will be set to the callback's return value. The callback 984445fffbSMatthew Ahrens * will be called with the following arguments: 994445fffbSMatthew Ahrens * 1004445fffbSMatthew Ahrens * const char *name 1014445fffbSMatthew Ahrens * The name of the pool or dataset to operate on, from 1024445fffbSMatthew Ahrens * zfs_cmd_t:zc_name. The 'namecheck' argument specifies the 1034445fffbSMatthew Ahrens * expected type (pool, dataset, or none). 1044445fffbSMatthew Ahrens * 1054445fffbSMatthew Ahrens * nvlist_t *innvl 1064445fffbSMatthew Ahrens * The input nvlist, deserialized from zfs_cmd_t:zc_nvlist_src. Or 1074445fffbSMatthew Ahrens * NULL if no input nvlist was provided. Changes to this nvlist are 1084445fffbSMatthew Ahrens * ignored. If the input nvlist could not be deserialized, the 1094445fffbSMatthew Ahrens * ioctl will fail and the callback will not be called. 1104445fffbSMatthew Ahrens * 1114445fffbSMatthew Ahrens * nvlist_t *outnvl 1124445fffbSMatthew Ahrens * The output nvlist, initially empty. The callback can fill it in, 1134445fffbSMatthew Ahrens * and it will be returned to userland by serializing it into 1144445fffbSMatthew Ahrens * zfs_cmd_t:zc_nvlist_dst. If it is non-empty, and serialization 1154445fffbSMatthew Ahrens * fails (e.g. because the caller didn't supply a large enough 1164445fffbSMatthew Ahrens * buffer), then the overall ioctl will fail. See the 1174445fffbSMatthew Ahrens * 'smush_nvlist' argument above for additional behaviors. 1184445fffbSMatthew Ahrens * 1194445fffbSMatthew Ahrens * There are two typical uses of the output nvlist: 1204445fffbSMatthew Ahrens * - To return state, e.g. property values. In this case, 1214445fffbSMatthew Ahrens * smush_outnvlist should be false. If the buffer was not large 1224445fffbSMatthew Ahrens * enough, the caller will reallocate a larger buffer and try 1234445fffbSMatthew Ahrens * the ioctl again. 1244445fffbSMatthew Ahrens * 1254445fffbSMatthew Ahrens * - To return multiple errors from an ioctl which makes on-disk 1264445fffbSMatthew Ahrens * changes. In this case, smush_outnvlist should be true. 1274445fffbSMatthew Ahrens * Ioctls which make on-disk modifications should generally not 1284445fffbSMatthew Ahrens * use the outnvl if they succeed, because the caller can not 1294445fffbSMatthew Ahrens * distinguish between the operation failing, and 1304445fffbSMatthew Ahrens * deserialization failing. 131e9103aaeSGarrett D'Amore */ 132fa9e4066Sahrens 133fa9e4066Sahrens #include <sys/types.h> 134fa9e4066Sahrens #include <sys/param.h> 135fa9e4066Sahrens #include <sys/errno.h> 136fa9e4066Sahrens #include <sys/uio.h> 137fa9e4066Sahrens #include <sys/buf.h> 138fa9e4066Sahrens #include <sys/modctl.h> 139fa9e4066Sahrens #include <sys/open.h> 140fa9e4066Sahrens #include <sys/file.h> 141fa9e4066Sahrens #include <sys/kmem.h> 142fa9e4066Sahrens #include <sys/conf.h> 143fa9e4066Sahrens #include <sys/cmn_err.h> 144fa9e4066Sahrens #include <sys/stat.h> 145fa9e4066Sahrens #include <sys/zfs_ioctl.h> 1464201a95eSRic Aleshire #include <sys/zfs_vfsops.h> 147da6c28aaSamw #include <sys/zfs_znode.h> 148fa9e4066Sahrens #include <sys/zap.h> 149fa9e4066Sahrens #include <sys/spa.h> 150b1b8ab34Slling #include <sys/spa_impl.h> 151fa9e4066Sahrens #include <sys/vdev.h> 1524201a95eSRic Aleshire #include <sys/priv_impl.h> 153fa9e4066Sahrens #include <sys/dmu.h> 154fa9e4066Sahrens #include <sys/dsl_dir.h> 155fa9e4066Sahrens #include <sys/dsl_dataset.h> 156fa9e4066Sahrens #include <sys/dsl_prop.h> 157ecd6cf80Smarks #include <sys/dsl_deleg.h> 158ecd6cf80Smarks #include <sys/dmu_objset.h> 1594e3c9f44SBill Pijewski #include <sys/dmu_impl.h> 1603b2aab18SMatthew Ahrens #include <sys/dmu_tx.h> 161fa9e4066Sahrens #include <sys/ddi.h> 162fa9e4066Sahrens #include <sys/sunddi.h> 163fa9e4066Sahrens #include <sys/sunldi.h> 164fa9e4066Sahrens #include <sys/policy.h> 165fa9e4066Sahrens #include <sys/zone.h> 166fa9e4066Sahrens #include <sys/nvpair.h> 167fa9e4066Sahrens #include <sys/pathname.h> 168fa9e4066Sahrens #include <sys/mount.h> 169fa9e4066Sahrens #include <sys/sdt.h> 170fa9e4066Sahrens #include <sys/fs/zfs.h> 171fa9e4066Sahrens #include <sys/zfs_ctldir.h> 172da6c28aaSamw #include <sys/zfs_dir.h> 173c99e4bdcSChris Kirby #include <sys/zfs_onexit.h> 174a2eea2e1Sahrens #include <sys/zvol.h> 1753f9d6ad7SLin Ling #include <sys/dsl_scan.h> 176ecd6cf80Smarks #include <sharefs/share.h> 177f18faf3fSek #include <sys/dmu_objset.h> 1783b2aab18SMatthew Ahrens #include <sys/dmu_send.h> 1793b2aab18SMatthew Ahrens #include <sys/dsl_destroy.h> 1803b2aab18SMatthew Ahrens #include <sys/dsl_userhold.h> 181a6f561b4SSašo Kiselkov #include <sys/zfeature.h> 182fa9e4066Sahrens 183fa9e4066Sahrens #include "zfs_namecheck.h" 184e9dbad6fSeschrock #include "zfs_prop.h" 185ecd6cf80Smarks #include "zfs_deleg.h" 1860a586ceaSMark Shellenbaum #include "zfs_comutil.h" 187fa9e4066Sahrens 188fa9e4066Sahrens extern struct modlfs zfs_modlfs;
