[SSSD] [sssd PR#455][opened] mmap_cache: make checks independent of input size

URL: https://github.com/SSSD/sssd/pull/455 Author: sumit-bose Title: #455: mmap_cache: make checks independent of input size Action: opened PR body: """ Currently the consistency checks for the mmap_cache payload data on the client and the responder side include the length of the input string of the current request. Since there might be hash collisions which other much longer or much shorter names those checks might fail although there is no data corruption. This patch removes the checks using the length of the input and adds a check if the name found in the payload is zero-terminated inside of the payload data. Resolves https://pagure.io/SSSD/sssd/issue/3571 """ To pull the PR as Git branch: git remote add ghsssd https://github.com/SSSD/sssd git fetch ghsssd pull/455/head:pr455 git checkout pr455
