The global sequence counter is an -- * unsigned 64-bit integer and we assume it never overflows. The @sqnum -- * (sequence number) is used to distinguish between older and newer versions of -- * logical eraseblocks. -- * -- * There are 2 situations when there may be more then one physical eraseblock -- * corresponding to the same logical eraseblock, i.e., having the same @vol_id -- * and @lnum values in the volume identifier header. Suppose we have a logical -- * eraseblock L and it is mapped to the physical eraseblock P. -- * -- * 1. Because UBI may erase physical eraseblocks asynchronously, the following -- * situation is possible: L is asynchronously erased, so P is scheduled for -- * erasure, then L is written to,i.e. mapped to another physical eraseblock P1, -- * so P1 is written to, then an unclean reboot happens. Result - there are 2 -- * physical eraseblocks P and P1 corresponding to the same logical eraseblock -- * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the -- * flash. -- * -- * 2. From time to time UBI moves logical eraseblocks to other physical -- * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P -- * to P1, and an unclean reboot happens before P is physically erased, there -- * are two physical eraseblocks P and P1 corresponding to L and UBI has to -- * select one of them when the flash is attached. The @sqnum field says which -- * PEB is the original (obviously P will have lower @sqnum) and the copy. But -- * it is not enough to select the physical eraseblock with the higher sequence -- * number, because the unclean reboot could have happen in the middle of the -- * copying process, so the data in P is corrupted. It is also not enough to -- * just select the physical eraseblock with lower sequence number, because the -- * data there may be old (consider a case if more data was added to P1 after -- * the copying). Moreover, the unclean reboot may happen when the erasure of P -- * was just started, so it result in unstable P, which is "mostly" OK, but -- * still has unstable bits. -- * -- * UBI uses the @copy_flag field to indicate that this logical eraseblock is a -- * copy. UBI also calculates data CRC when the data is moved and stores it at -- * the @data_crc field of the copy (P1). So when UBI needs to pick one physical -- * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is -- * examined. If it is cleared, the situation* is simple and the newer one is -- * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC -- * checksum is correct, this physical eraseblock is selected (P1). Otherwise -- * the older one (P) is selected. -- * -- * Note, there is an obsolete @leb_ver field which was used instead of @sqnum -- * in the past. But it is not used anymore and we keep it in order to be able -- * to deal with old UBI images. It will be removed at some point. -- * -- * There are 2 sorts of volumes in UBI: user volumes and internal volumes. -- * Internal volumes are not seen from outside and are used for various internal -- * UBI purposes. In this implementation there is only one internal volume - the -- * layout volume. Internal volumes are the main mechanism of UBI extensions. -- * For example, in future one may introduce a journal internal volume. Internal -- * volumes have their own reserved range of IDs. -- * -- * The @compat field is only used for internal volumes and contains the "degree -- * of their compatibility". It is always zero for user volumes. This field -- * provides a mechanism to introduce UBI extensions and to be still compatible -- * with older UBI binaries. For example, if someone introduced a journal in -- * future, he would probably use %UBI_COMPAT_DELETE compatibility for the -- * journal volume. And in this case, older UBI binaries, which know nothing -- * about the journal volume, would just delete this volume and work perfectly -- * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image -- * - it just ignores the Ext3fs journal. -- * -- * The @data_crc field contains the CRC checksum of the contents of the logical -- * eraseblock if this is a static volume. In case of dynamic volumes, it does -- * not contain the CRC checksum as a rule. The only exception is when the -- * data of the physical eraseblock was moved by the wear-leveling unit, then -- * the wear-leveling unit calculates the data CRC and stores it in the -- * @data_crc field. And of course, the @copy_flag is %in this case. -- * -- * The @data_size field is used only for static volumes because UBI has to know -- * how many bytes of data are stored in this eraseblock. For dynamic volumes, -- * this field usually contains zero. The only exception is when the data of the -- * physical eraseblock was moved to another physical eraseblock for -- * wear-leveling reasons. In this case, UBI calculates CRC checksum of the -- * contents and uses both @data_crc and @data_size fields. In this case, the -- * @data_size field contains data size. -- * -- * The @used_ebs field is used only for static volumes and indicates how many -- * eraseblocks the data of the volume takes. For dynamic volumes this field is -- * not used and always contains zero. -- * -- * The @data_pad is calculated when volumes are created using the alignment -- * parameter. So, effectively, the @data_pad field reduces the size of logical -- * eraseblocks of this volume. This is very handy when one uses block-oriented -- * software (say, cramfs) on top of the UBI volume. -- */ --struct ubi_vid_hdr { -- __be32 magic; -- __u8 version; -- __u8 vol_type; -- __u8 copy_flag; -- __u8 compat; -- __be32 vol_id; -- __be32 lnum; -- __be32 leb_ver; /* obsolete, to be removed, don't use */ -- __be32 data_size; -- __be32 used_ebs; -- __be32 data_pad; -- __be32 data_crc; -- __u8 padding1[4]; -- __be64 sqnum; -- __u8 padding2[12]; -- __be32 hdr_crc; --} __attribute__ ((packed)); -- --/* Internal UBI volumes count */ --#define UBI_INT_VOL_COUNT 1 -- --/* -- * Starting ID of internal volumes.
