In order to solve the above-mentioned technical problem, the embodiment of the present application provides following solution.
As shown in figure 5, Fig. 5 is a kind of flow diagram of difference upgrade method provided by the embodiments of the present application.The application
Step in embodiment includes at least:
S501 obtains the difference packet for difference upgrading when detecting to the progress differencing check failure of multiple data blocks,
The difference packet includes differential data, determines the cryptographic Hash of each data block in the multiple data block in electronic equipment, with
And each data block of the multiple data block of original version is obtained from the Hash tree at the difference packet or mirror image end
Cryptographic Hash.
Wherein, multiple data blocks can be the file in the data block or file system in memory device.The difference
Data are the variance data between the data for the version that currently data of more new version and electronic equipment currently save.It is the multiple
Data block is variance data block, that is, the data block for needing to upgrade, difference includes not needing the data of the data block of upgrading.Institute
The subregion mirror image that mirror image is the multiple data blocks upgraded to difference is stated, memory device may include embedded multi-media card
(embedded multi media card, EMMC), unix filesystem (unix file system, UFS) etc., every number
Size according to block includes but is not limited to 4k.
Specifically, can from server obtain for difference upgrade difference packet, difference upgrading start after, first into
Row differencing check calculates a hash value of all data in electronic equipment in multiple variance data blocks, the difference packet
A hash value of multiple variance data blocks of original version is included, if two hash values are identical, differencing check success can be with
Directly carry out difference upgrading.If two hash are not identical, difference verification failure illustrates the original version in electronic equipment
Changed for some reason, the abnormal data block required to look up out in multiple variance data blocks carries out error correction, so
Difference upgrading can be just carried out afterwards.
Optionally, before carrying out difference upgrading to multiple data blocks, difference packet can be generated.As shown in fig. 6, Fig. 6 is
A kind of flow diagram of difference packet generation method provided by the embodiments of the present application.It include: currently to be saved to electronic equipment first
The data of version A and the data of current more new version B be compared, determine differential data, and differential data is packaged and is generated
Difference packet.The difference packet can also include the corresponding hash value of multiple data blocks, which is according in multiple data blocks
What all data of original version were calculated.
Wherein, for the system (such as part Android version) with hash data and error correcting code, hash value and error correction
Code is placed on mirror image end, and difference packet can only include differential data.Alternatively, can be by the value range of the data block of each file
It is recorded in difference packet, the value range of the data block is used for when carrying out difference upgrading to the file in file system from mirror image end
The hash value of corresponding data block is searched in the Hash tree of tail.For no hash data and error correcting code system (such as other one
A little systems), difference packet can also include the hash value and error correcting code of multiple data blocks, the corresponding hash value of data block and
One error correcting code, the hash value are to be calculated according to the data of the original version in each data block.
For example, including 1000 data blocks in the memory device of electronic equipment, currently the data of more new version are set with electronics
The data of the standby version currently saved are compared, and determination only needs to be updated 100 data blocks in memory device, and another
900 outer data blocks do not need to update, and differential data is the data of 100 data blocks.In the difference packet ultimately generated
May include the data of 100 data blocks, difference packet also may include 100 data blocks 100 data blocks of data and 100
Hash value, a corresponding hash value of data block and an error correcting code.
For the system with hash data and error correcting code, when carrying out difference upgrading to the data block in memory device,
If multiple data block differencing check failures, can search original version from the Hash tree (hash tree) at mirror image end
Each data block hash value.When carrying out difference upgrading to the file in file system, if file differencing check fails,
The value range that the data block of this document is then read from difference packet is searched from the Hash tree at mirror image end according to the value range
To the hash to each data block.For the system (such as some other system) of no hash data and error correcting code, making
The hash value of each data block of differential data and error correcting code have been saved in difference packet when difference packet.To data block
When carrying out difference upgrading, if multiple data block differencing checks fail, each data block can be obtained from difference packet
Hash value.
S502, determine the first data block in the multiple data block that the difference packet is included the first cryptographic Hash,
It is whether identical as the second cryptographic Hash of the first data block in the multiple data block in the electronic equipment.Wherein, first
Cryptographic Hash is to be calculated according to the data of the original version in the first data block, and the second cryptographic Hash is that electronic equipment is currently protected
What the data in the first data block deposited were calculated, if not identical, S503 is executed, if they are the same, then executes S504.
For example, difference packet include 100 data blocks (data block 1, data block 2 ... ..., data block 100) data and
100 hash values, the corresponding hash value of a data block, can be respectively by the original hash value of data block each in difference packet
The hash value of the corresponding data block currently saved with electronic equipment is compared, if it is determined that the hash value of data block 1 not phase
With and data block 2 hash value it is also not identical, then illustrate that the data in data block 1 and data block 2 are changed, Wu Fajin
The upgrading of row difference, therefore only need to carry out error correction to the data in data block 1 and data block 2.If the hash of other data blocks
Be worth it is identical, then do not need carry out error correction.
It should be noted that in the case where multiple data blocks corresponding hash value, as long as one in multiple data blocks
Data in data block change, then the hash value being calculated is with regard to different.Hash value included in subpackage of being on duty with
Electronic equipment be calculated multiple data blocks of original version hash value it is not identical when, then need in all multiple data blocks
Data carry out error correction.And in the embodiment of the present application, the corresponding hash value of a data block, if it is determined that some data block
Hash it is not identical, then only need in the data block data carry out error correction, to improve data-handling efficiency.
S503 calls the Forward Error Correction FEC functional interface of User space, carries out to the abnormal data in first data block
Error correction, and first data block is written into the correct data after error correction.
Specifically, Forward Error Correction FEC functional interface can be encapsulated under User space in advance.It is carried out under recovery mode
Difference upgrade when, the Forward Error Correction FEC functional interface of User space can be called, to the abnormal data in first data block into
Row error correction, and first data block is written into the correct data after error correction.
It is former from being searched in the Hash tree (hash tree) at mirror image end for the system with hash data and error correcting code
The hash value of multiple data blocks of beginning version, then with the multiple data blocks for the current version being calculated in electronic equipment
Hash value is compared, and finds out the data block of difference, then carries out error correction using the error correcting code that mirror image end saves.If to text
File in part system carries out difference upgrading.The value range that the data block of this document is read from difference packet, according to the value range,
The hash that corresponding data block is found from the Hash tree at mirror image end, with the current version that is calculated in electronic equipment
Hash is compared, and finds out the data block of difference, then carries out error correction using the error correcting code that mirror image end saves.
It, will be poor when making the difference subpackage for the system (such as some other system) of no hash data and error correcting code
The hash value and error correcting code of each data block of divided data have been saved in difference packet.Every number can be obtained from difference packet
According to the hash value of block, it is compared, finds out with the hash value of the multiple data blocks for the current version being calculated in electronic equipment
Then the data block of difference carries out error correction using the error correcting code saved in difference packet.
For example, having verified that the mirror image of starting (Android verified boot, AVB) verification for non-Android, i.e.,
The hash tree of mirror image data is not saved in mirror image end, such as kernel mirror image, boot ramdisk mirror image etc., it can
When generating difference packet, the hash value and error correcting code of variance data block to be stored in difference packet.If the number in difference packet
The hash value of the data block 1 currently saved saved according to hash value and the electronic equipment of block 1 is not identical, then illustrates that the electronics is set
The data of the standby data block 1 currently saved are abnormal data, and the error correcting code for the data block 1 for including in difference packet can be used at this time
Error correction is carried out to the abnormal data, and by the correct data writing data blocks 1 after error correction.
Optionally, after carrying out error correction to the data in the first data block, the hash value of the data after error correction is calculated again,
And be compared the hash value for the first data block that the hash value and the Hash tree of difference packet or mirror image end include, if phase
Together, then the data after error correction are correct data, which are written the first data block, if it is not the same, then after error correction
Data are wrong data, need further to carry out error correction to the data.
S504 verifies other data blocks in the multiple data block.It can be according to above-mentioned identical method pair
Other data blocks are verified, until multiple data block complete verifications finish.
S505, when the success of the multiple data block complete verification, using the differential data to the multiple data block
Upgraded.Specifically, hash value and difference packet or the mirror image end of each data block being calculated in the electronic equipment
When the hash value for the corresponding data block that Hash tree includes is all identical, then the error correction of specification exception data block finishes, and starts to carry out
Difference upgrading.
In the embodiment of the present application, by encapsulating the FEC interface of User space, when differencing check failure, pass through calling pair
The FEC interface of User space corrects the data in data block, and the data block is written in the correct data after correction, thus
It realizes self-repair function when difference upgrading failure, improves the efficiency and success rate of difference upgrading.
