Pacific: RadosGW crashing on multipart uploads.

29 Jun 2021

      Hi, I'm running into an issue with RadosGW where multipart uploads crash, but only on buckets with a hyphen, period or underscore in the bucket name and with a bucket policy applied. We've tested this in pacific 16.2.3 and pacific 16.2.4.

Anyone run into this before?

ubuntu@ubuntu:~/ubuntu$ aws --endpoint http://placeholder.com:7480 s3 cp ubuntu.iso s3://bucket.test

upload failed: ./ubuntu.iso to s3://bucket.test/ubuntu.iso Connection was closed before we received a valid response from endpoint URL: "http://placeholder.com:7480/bucket.test/ubuntu.iso?uploads".

Here is the crash log.
