libcap-2.52

[Bruce Dubbs]

New minor version.

Release notes for 2.52 -- 2021-08-01 17:49:56 -0700

• Revived -std=c89 compilation for make all etc.

• The shared library objects: pam_cap.so, libcap.so and libpsx.so, are all now runnable as standalone binaries!

• The support is used to display some description information.
• To activate it, these binaries need to be installed executable (chmod +x ...)
• We also provided a write-up of how to enable this sort of feature in other .so files here.

• The module pam_cap.so now contains support for a default=<IAB> module argument.

• Enhanced capsh --suggest to also compare against the capability value names and not just their descriptions.

• Added capsh --current support.

• Minor documentation updates.

• Added a contrib/sucap/su.c pure-capabilities PAM implementation of su.
  • This is primarily to demonstrate that such a thing is possible, and to validate that the pam_cap.so module is capable of adding any IAB tuple of inheritables per group or user.
  • At this time, it relies on features only present in this version of libcap and HEAD of the Linux-PAM sources for the pam_unix.so module.
