Issue ID: 10214
Summary: Reduce library dependencies
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: Linux
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal
Priority: ---
Component: slapd
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Currently, slapd links libsystemd to notify service state to systemd.
However, libsystemd link several unnecessary libraries, which increases
security risks.
The systemd documentation provides a method to send state notifications to
systemd using a simple protocol without the need to link against libsystemd.
https://www.freedesktop.org/software/systemd/man/devel/sd_notify.html
I propose removing libsystemd and its depended libraries, similar to the
approach taken by OpenSSH.
Applying this fix reduced the following ten dependencies in the RHEL 8
environment.
- libsystemd.so.0
- libblkid.so.1
- libcap.so.2
- libgcc_s.so.1
- libgcrypt.so.20
- libgpg-error.so.0
- liblz4.so.1
- liblzma.so.5
- libmount.so.1
- librt.so.1
