[Bug 2052813] Re: [MIR] bpfcc

[Robie Basak]

The main user story being implemented here is the one specified by
Brendan Gregg in his literature, including his book "Systems
Performance, 2nd Edition". In that book he specifies "Linux crisis tool
packages" [Table 4.1], which specifies bpfcc-tools and a bunch of
binaries provided by that.

Looking at the difference between libbpf-tools and bpfcc-tools, the
former is only a subset and doesn't include all the tools specified in
the book. For example, the book covers trace and argdist in section
15.1.6. These have -bpfcc versions provided by bpfcc-tools, but I don't
see any equivalents in libbpf-tools.

The intention is that we install by default what the book covers.
Therefore, I'd like to request (at least initially) that we have bpfcc-
tools in main. If that's not possible then libbpf-tools will be better
than nothing, but will add to the caveats in this entire effort.

Please could you consider the MIR request to be for the bpfcc-tools
binary package?

Title:
  [MIR] bpfcc

Status in bpfcc package in Ubuntu:
  Incomplete

Bug description:
  [Availability]
  - The package bpfcc is already in Ubuntu universe.
  - The package bpfcc build for the architectures it is designed to work on.
  - It currently builds and works for architectures: any
  - Link to package https://launchpad.net/ubuntu/+source/bpfcc

  [Rationale]
  - The package bpfcc is required in Ubuntu main as a runtime dependency of
    bpftrace.
  - There is no other/better way to solve this that is already in main or
    should go universe->main instead of this.
  - The package bpftrace is required in Ubuntu main as part of the Noble Numbat
    realease, and hence should be promoted to main before NN feature freeze.

  [Security]
  - No CVEs/security issues in this software in the past
  - no `suid` or `sgid` binaries
  - Binaries *-bpfcc in sbin are no problem because they are part of the
    expected functionality of the package
  - Package does not install services, timers or recurring jobs
  - Security has been kept in mind and common isolation/risk-mitigation
    patterns are in place utilizing the following features:
    the package is a debugging tool, and cannot be fully isolated.
  - Packages does not open privileged ports (ports < 1024).
  - Package does not expose any external endpoints
  - Packages does not contain extensions to security-sensitive software
    (filters, scanners, plugins, UI skins, ...)

  [Quality assurance - function/usage]
  - The package works well right after install

  [Quality assurance - maintenance]
  - The package is maintained well in Debian/Ubuntu/Upstream and does
    not have too many, long-term & critical, open bugs
    - Ubuntu https://bugs.launchpad.net/ubuntu/+source/bpfcc/+bug
    - Debian https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=bpfcc
    - Upstream's bug tracker, e.g., GitHub Issues
      https://github.com/iovisor/bcc/issues
  - The package has important open bugs, listing them:
     https://bugs.launchpad.net/ubuntu/+source/bpfcc/+bug/1969626
  - The package does not deal with exotic hardware we cannot support

  [Quality assurance - testing]
  - The package does not run a test at build time
    (Potential issue?)
  - The package does not run an autopkgtest
    (Potential issue?)
  - The package does have not failing autopkgtests right now

  [Quality assurance - packaging]
  - debian/watch is present and works
  - debian/control defines a correct Maintainer field
  - This package does not yield massive lintian Warnings, Errors
  - Please link to a recent build log of the package
    https://launchpadlibrarian.net/703777424/buildlog_ubuntu-noble-amd64.bpfcc_0.29.1+ds-1ubuntu2_BUILDING.txt.gz
  - Please attach the full output you have got from `lintian --pedantic` as an
    extra post to this bug:
    ```
    E: bpfcc changes: bad-distribution-in-changes-file noble
    W: bpfcc source: no-nmu-in-changelog [debian/changelog:1]
    W: bpfcc source: source-nmu-has-incorrect-version-number 0.29.1+ds-1ubuntu2 [debian/changelog:1]
    P: bpfcc source: trailing-whitespace [debian/changelog:41]
    ```
  - Lintian overrides are present, they disable warnings about the lack of manpages
    (Potential issue?)
  - This package does not rely on obsolete or about to be demoted packages.
  - This package has no python2 or GTK2 dependencies
  - The package will not be installed by default
  - Packaging and build is easy, link to debian/rules
    https://git.launchpad.net/ubuntu/+source/bpfcc/tree/debian/rules?h=ubuntu/noble

  [UI standards]
  - Application is not end-user facing (does not need translation)

  [Dependencies]
  - No further depends or recommends dependencies that are not yet in main

  [Standards compliance]
  - This package correctly follows FHS and Debian Policy

  [Maintenance/Owner]
  - The owning team will be Foundations and I have their acknowledgement for
    that commitment
  - The future owning team is not yet subscribed, but will subscribe to
    the package before promotion
  - This does not use static builds
  - This does not use vendored code
  - This package is not rust based
  - The package successfully built during the most recent test rebuild

  [Background information]
  - The Package description explains the package well
  - Upstream Name is bcc
  - Link to upstream project bcc: https://github.com/iovisor/bcc
