Accompanying drawing explanation
Fig. 1 is the method flow diagram of the image upgrade method of a kind of switch of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate specific embodiments of the invention.
As shown in Figure 1, be a kind of embodiment being applicable to the image upgrade method of the switch of linux operating system, the method comprises:
Step 1, generation linux kernel mirror image file vmlinuxz.
The kernel of step 1.1, compiling linux operating system.First specify compiling path, select the parameter that some will compile, use the kernel of make order to linux operating system to compile.
Step 1.2, by compiling after kernel carry out being compressed into kernel mirror image file vmlinuxz.
Step 1.3, first being upgraded by kernel mirror image file vmlinuxz is loaded into flash subarea.
Step 2, sdk(Software Development Kit, Software tool kit) and hsl(Hardware System Layer, hardware system layer) compiling generate suffix be .ko(kernel object, kernel objects) first object file, i.e. .ko file.
Those .ko files are Dynamic link library files that linux2.6 kernel uses, and this .ko file is some drivers of exchange chip, for the normal work of driving chip, load kernel module when linux system starts.
Current ko file has: hsl_bcm.ko(compiles the ko that hsl generates), the ko of linux-bcm-diag.ko (ko of debugging module), linux-kernel-bde.ko(kernel), the ko of linux-bcm-core.ko (ko of driver), linux-uk-proxy.ko(agency) etc.
Step 3, the first operating system compile out the second file destination, and this second file destination is the module of some application layers.
In the present embodiment, the first operating system adopts FOS(feixun operating system) striking news operating system, this FOS function class is like Zebos operating system.
A lot of executable files can be generated after compiling FOS, these executable files are exactly the module of some concrete application layers of hereinafter mentioned generation, be respectively: the application protocol module of the application layers such as authd, imi, lacpd, mstpd, nldpd, nsm, ospfd, pdmd, pimd, ripd, webserver, these modules are that switch normally works the agreement of required operation, the loading success only having these modules normally complete, switch could realize corresponding function.
Wherein, the driver of sdk mainly exchange chip.
Hsl connects the middle layer of FOS and sdk, when that is the application program module on upper strata needs the relative program calling bottom sdk, all can carry out transfer by hsl layer, but it is also belong to kernel module.
The difference that the first object file that sdk and hsl compiling generates and FOS compile the second file destination generated is, is in the different levels of switch, but is all that switch normally runs necessary file destination.What Sdk and hsl compiling generated is. ko file, is in bottom, and FOS compiling generation is some executable application program modules, is in upper strata, namely application layer.
The first object file that step 4, sdk, hsl and FOS compiling generate and the second file destination generate the file system mirror file of keystone.jffs2 by name by the compression of automatically packing of the script of a compression of carrying out packing.
Here, first object file and the second file destination are carried out the script compressed of packing, specifically use tar-cjvf tfile sfile order, carry out packing compression.Wherein cjvf indicates to want pack compression and the file type after compressing, and Tfile is exactly the filename generated after packing compression, and sfile is exactly source file destination, i.e. those file destinations that are packaged and compression.
Step 5, kernel mirror image file vmlinuxz and file system mirror file keystone.jffs2 are automatically packed by the script that compresses of carrying out packing and compress, and generate the image file that can be used for the direct image upgrade of switch that a suffix is .gz.
Here, script in the script that kernel mirror image file vmlinuxz and file system mirror file keystone.jffs2 being carried out packs compresses and step 4 is the same, be all adopt tar order to compress, just source file destination sfile is different with the filename Tfile generated after packing compression.
The feature that can be used for the image file of the direct image upgrade of switch is exactly, it is the new Jffs2 file system kernel mirror image file of above-mentioned a lot of module and .KO file composition and file system mirror file packing compression generated, can save us so progressively to the application module on upper strata and the flash of write one by one of those ko file hands, save time cost.
Step 6, by tftp file transfer conveyance, by can be used for the flash subarea of the burned switch of image file that switch mirror image is directly upgraded, complete the upgrading of switch.
The present invention also discloses a kind of switch of linux operating system, and the switch of this linux operating system is applicable to the image upgrade method of above-mentioned switch.
The present invention also discloses a kind of linux operating system, and this linux operating system includes switch, and this switch is applicable to the image upgrade method of above-mentioned switch.
