Mitch Walker 7f891e5db7 add_key.2: Empty payloads are not allowed in user-defined keys 
iBoth add_key and the utility "keyctl add" return EINVAL when
attempting to add a user key with an empty or NULL payload.

The manpage implies that this should be valid.

From my reading of the kernel source, this has not been possible
since at least linux kernel commit 1da177e4 (2.6.12-rc2 on
2005-04-16).

Until kernel commit cf7f601c,
security/keys/user_defined.c:user_instantiate returned -EINVAL
if datalen <= 0.  That commit only moved this behavior to a new
user_preparse function, where it remains today in b562e44f
(4.5.0 on 2016-03-13).

README 

This package contains Linux man pages for sections
2, 3, 4, 5, and 7. Some more information is given in the
`Announce' file.

Install by copying to your favourite location.
"make install" will just copy them to /usr/share/man/man[1-8].
To install to a path different from /usr use
"make install prefix=/install/path".
"make" will move the pages from this package that are older than
the already installed ones to a subdirectory `not_installed',
then remove old versions (compressed or not),
compress the pages, and copy them to /usr/share/man/man[1-8].


Note that you may have to remove preformatted pages.

Note that sometimes these pages are duplicates of pages
also distributed in other packages. This has been reported
about dlclose.3, dlerror.3, dlopen.3, dlsym.3 (found in ld.so),
about resolver.3, resolv.conf.5 (found in bind-utils),
and about passwd.5, and mailaddr.7. Be careful not to
overwrite more up-to-date versions.
Reports on further duplicates are welcome.
Formerly present and now removed duplicates:
 exports.5 (found in nfs-server-2.2*),
 fstab.5, nfs.5 (found in util-linux-2.12*),
 lilo.8, lilo.conf.5 (found in lilo-21.6*).

Copyrights: These man pages come under various copyrights.
All pages are freely distributable when the nroff source is included.
