From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yann E. MORIN Date: Fri, 8 Feb 2013 23:06:48 +0100 Subject: [Buildroot] [pull request v6] Pull request for branch yem-package-create-user Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Hello All! Here is a series that allows packages to create users. Packages that install daemons may well want to run those daemons as non-root users to avoid security issues. Currently, there are two users of choice to run 'generic' daemons: root or daemon (although there are a few dedicated users to run a few services: mail, sshd, ftp...). This series builds upon both the package infrastrucutre to define the user(s) a package may want to create, and the filesystem infrastructure to actually generate these users, and chown their ${HOME}s. Documentation is updated accordingly. As a proof of concept, the package tvheadend has been updated to use a dedicated user to run its daemon as (call me stubborn! ;-] ). Changes v5 -> v6: (All after suggestions by Arnout) - clean up awk invocations - ensure users with an explicit uid are created before users with a computed uid - ditto for groups/gid - cleanup group-addign function - fix password encoding method - cleanup /etc/shadow fields - fix typos Changes v4 -> v5: - rebased ontop master after Developer's Day comments and upstreaming Changes v3 -> v4: - use the configured password encryption scheme - some tweaks and typo-fixes to the documentation Changes v2 -> v3: - clarify password prefixes (Samuel) - move makeuser syntax doc to its own file (Samuel) - use awk instead of sed to parse /etc/passwd et al. (Cam, Thomas) - sanitise use of grep (Cam) - enhancements and fixes to makuser syntax doc (Cam) Changes v1 -> v2: - drop the gshadow patch (Thomas, Peter) - tvheadend user is now part of the video secondary group The following changes since commit 5ff6989445eac9ce59a5041c656bcb0319dce0eb: libgpg-error: use _CONFIG_SCRIPTS (2013-02-08 22:41:40 +0100) are available in the git repository at: git://gitorious.org/buildroot/buildroot.git yem-package-create-user Yann E.
