We can replace system includes with git-compat-util.h or cache.h (and should make sure it is included first in all C files). And we can drop includes from headers entirely, as every C file should include git-compat-util.h itself. We will add in new include guards around the header files, though (otherwise you get into trouble including both sha1dc/sha1.h and cache.h). And finally, we'll use the full "sha1dc/" path for including related files. This isn't strictly necessary, but makes the expected resolution more obvious.

// sha1_dvs contains a list of SHA-1 Disturbance Vectors (DV) to check
|
|
// dvType, dvK and dvB define the DV: I(K,B) or II(K,B) (see the paper)
|
|
// dm[80] is the expanded message block XOR-difference defined by the DV
|
|
// testt is the step to do the recompression from for collision detection
|
|
// maski and maskb define the bit to check for each DV in the dvmask returned by ubc_check
|
|
//
|
|
// ubc_check takes as input an expanded message block and verifies the unavoidable bitconditions for all listed DVs
|
|
// it returns a dvmask where each bit belonging to a DV is set if all unavoidable bitconditions for that DV have been met
|
|
// thus one needs to do the recompression check for each DV that has its bit set
