Description of problem: When a customer has a bcc revision older than bcc-0.11.0-2.el8.x86_64.rpm, a libbpf library is present in the /usr/lib64/ directory as the following: # rpm -qlp bcc-0.8.0-4.el8.x86_64.rpm | grep bpf /usr/lib64/libbpf.so.0 /usr/lib64/libbpf.so.0.8.0 This conflicts with the libbpf component introduced in the 8.2.0 release. # rpm -qlp libbpf-0.0.4-5.el8.x86_64.rpm | grep bpf /usr/lib64/libbpf.so.0 /usr/lib64/libbpf.so.0.0.4 As a result, customers using "yum update --security" encounter failures. Version-Release number of selected component (if applicable): bcc-0.11.0-2.el8 How reproducible: Easily Steps to Reproduce: 1. Install bcc-0.8.0-4.el8 or bcc-0.7.0-5.el8 # yum install bcc-0.8.0-4.el8 2. Install perf-4.18.0-147.5.1.el8_1.x86_64 # yum install perf-4.18.0-147.5.1.el8_1.x86_64 3. Use the security modifier for yum update # yum update --security Actual results: # yum update --security Updating Subscription Management repositories.

Additional info: In the above, perf has a security errata notice and gets pulled into the transaction. The libbpf component gets added as a dependency of the new perf revision, but it then conflicts with the already installed older bcc revision. The simplest workaround is to just update bcc prior to issuing the above update. # yum update bcc -y That will avoid the condition by updating to a revision of bcc that already has the libbcc_bpf rename in place. # rpm -qlp bcc-0.11.0-2.el8.x86_64.rpm | grep bpf /usr/lib64/libbcc_bpf.so.0 /usr/lib64/libbcc_bpf.so.0.11.0
