Test negative size in memmove in order to verify whether it correctly get KASAN report. Casting negative numbers to size_t would indeed turn up as a large size_t, so it will have out-of-bounds bug and be detected by KASAN.

We lost something?In response to [1/2] Andrey said "So let's keep this code as this" and you said "I will send a new v5 patch tomorrow". So we're awaiting a v5 patchset?
Hi Andrew, The [1/2] patch discussion shows below. Thanks for Dimitry help to explain it. So that v4 patchset got Andrey's signature. Because I see Andrey said "But I see you point now. No objections to the patch in that case." @Andrey, if I have an incorrect understanding, please let me know. Thanks for your help. https://lkml.org/lkml/2019/11/21/1019 https://lkml.org/lkml/2019/11/21/1020 Walter _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
