0xffffffff00000000ULL mask does not take into consideration signed 32 bit integers and as result 2147483648 will be stored as -2147483648. Another mask should be used to correct the issue: 0xffffffff80000000ULL. It processes correctly the case of integers that are greater than 2147483647. There are several gdb tests below: (gdb) p ((unsigned long long)2147483648 & 0xffffffff80000000ULL) $1= 2147483648 (gdb) p ((unsigned long long)2147483647 & 0xffffffff80000000ULL) $2 = 0 (gdb) p ((unsigned long long)2147483646 & 0xffffffff80000000ULL) $3 = 0 (gdb) p ((unsigned long long)4147483646 & 0xffffffff80000000ULL) $4 = 2147483648 <!-- Kamailio Pull Request Template --> <!-- IMPORTANT: - for detailed contributing guidelines, read: https://github.com/kamailio/kamailio/blob/master/.github/CONTRIBUTING.md - pull requests must be done to master branch, unless they are backports of fixes from master branch to a stable branch - backports to stable branches must be done with 'git cherry-pick -x ...' - code is contributed under BSD for core and main components (tm, sl, auth, tls) - code is contributed GPLv2 or a compatible license for the other components - GPL code is contributed with OpenSSL licensing exception --> #### Pre-Submission Checklist <!-- Go over all points below, and after creating the PR, tick all the checkboxes that apply --> <!-- All points should be verified, otherwise, read the CONTRIBUTING guidelines from above--> <!-- If you're unsure about any of these, don't hesitate to ask on sr-dev mailing list --> - [ ] Commit message has the format required by CONTRIBUTING guide - [ ] Commits are split per component (core, individual modules, libs, utils, ...) - [ ] Each component has a single commit (if not, squash them into one commit) - [ ] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [ ] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist: <!-- Go over all points below, and after creating the PR, tick the checkboxes that apply --> - [ ] PR should be backported to stable branches - [ ] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description <!-- Describe your changes in detail --> You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/2106 -- Commit Summary -- * lib: big integers should not be treated as negative ones -- File Changes -- M src/lib/srdb1/db_ut.c (2) -- Patch Links -- https://github.com/kamailio/kamailio/pull/2106.patch https://github.com/kamailio/kamailio/pull/2106.diff -- You are receiving this because you are subscribed to this thread.
