# the (optional) BPF feature requires bpftool, libbpf, clang and llvm-strip to be available during build time.
# Only libbpf should be a runtime dependency.
# Note: llvmPackages is explicitly taken from buildPackages instead of relying
# on splicing. Splicing will evaluate the adjacent (pkgsHostTarget) llvmPackages
# which is sometimes problematic: llvmPackages.clang looks at targetPackages.stdenv.cc
# which, in the unfortunate case of pkgsCross.ghcjs, `throw`s. If we explicitly
# take buildPackages.llvmPackages, this is no problem because
# `buildPackages.targetPackages.stdenv.cc == stdenv.cc` relative to us. Working
# around this is important, because systemd is in the dependency closure of

# The following patches references to dynamic libraries to ensure that
# all the features that are implemented via dlopen(3) are available (or

# instead of relying on the linkers runtime lookup code.
#
# All of the shared library references have to be handled. When new ones
# are introduced by upstream (or one of our patches) they must be
# explicitly declared, otherwise the build will fail.
#
# As of systemd version 247 we've seen a few errors like `libpcre2.… not
# found` when using e.g. --grep with journalctl. Those errors should
# become less unexpected now.
#
# There are generally two classes of dlopen(3) calls. Those that we want to
# support and those that should be deactivated / unsupported. This change
# enforces that we handle all dlopen calls explicitly. Meaning: There is
# not a single dlopen call in the source code tree that we did not
# explicitly handle.
#
# In order to do this we introduced a list of attributes that maps from
# shared object name to the package that contains them. The package can be
# null meaning the reference should be nuked and the shared object will
# never be loadable during runtime (because it points at an invalid store
# path location).
#
# To get a list of dynamically loaded libraries issue something like
# `grep -ri '"lib[a-zA-Z0-9-]*\.so[\.0-9a-zA-z]*"'' $src` and update the below list.
