From: Matan Shachnai
Date: Sat Dec 14 2024 - 14:04:34 EST
Hi All,
This patch-set aims to improve precision of BPF_MUL and add testcases
to illustrate precision gains using signed and unsigned bounds.
Thanks for taking the time to review and specifically for Eduard's feedback!
Best,
Matan
Changes from v1:
- Fixed typo made in patch
Changes from v2:
- Added signed multiplication to BPF_MUL
- Added test cases to exercise BPF_MUL
- Reordered patches in the series.
