Subject: [bpf PATCH 0/3] verifier fix for assigning 32bit reg to 64bit reg
Date: Fri, 29 May 2020 10:28:21 -0700	[thread overview]
Message-ID: <159077324869.6014.6516130782021506562.stgit@john-Precision-5820-Tower> (raw)

These add a fix for 32 bit to 64 bit assignment introduced with
latest alu32 bounds tracking. The initial fix was proposed by
Yonghong and then I updated it slightly and added a test fix.

@Yonghong feel free to add your signed-off-by back if you want
or at minimal a ACK would be good.
