subids: support nsswitch Closes #154 When starting any operation to do with subuid delegation, check nsswitch for a module to use. If none is specified, then use the traditional /etc/subuid and /etc/subgid files. Currently only one module is supported, and there is no fallback to the files on errors. Several possibilities could be considered: 1. in case of connection error, fall back to files 2. in case of unknown user, also fall back to files etc... When non-files nss module is used, functions to edit the range are not supported. It may make sense to support it, but it also may make sense to require another tool to be used. libsubordinateio also uses the nss_ helpers. This is how for instance lxc could easily be converted to supporting nsswitch. Add a set of test cases, including a dummy libsubid_zzz module. This hardcodes values such that: 'ubuntu' gets 200000 - 300000 'user1' gets 100000 - 165536 'error' emulates an nss module error 'unknown' emulates a user unknown to the nss module 'conn' emulates a connection error ot the nss module Changes to libsubid: Change the list_owner_ranges api: return a count instead of making the array null terminated. This is a breaking change, so bump the libsubid abi major number. Rename free_subuid_range and free_subgid_range to ungrant_subuid_range, because otherwise it's confusing with free_subid_ranges which frees memory. Run libsubid tests in jenkins Switch argument order in find_subid_owners Move the db locking into subordinateio.c Signed-off-by: Serge Hallyn <serge@hallyn.com>

Flush sssd caches in addition to nscd caches Some distributions, notably Fedora, have the following order of nsswitch modules by default: passwd: sss files group: sss files The advantage of serving local users through SSSD is that the nss_sss module has a fast mmapped-cache that speeds up NSS lookups compared to accessing the disk an opening the files on each NSS request. Traditionally, this has been done with the help of nscd, but using nscd in parallel with sssd is cumbersome, as both SSSD and nscd use their own independent caching, so using nscd in setups where sssd is also serving users from some remote domain (LDAP, AD, ...) can result in a bit of unpredictability. More details about why Fedora chose to use sss before files can be found on e.g.: https://fedoraproject.org//wiki/Changes/SSSDCacheForLocalUsers or: https://docs.pagure.org/SSSD.sssd/design_pages/files_provider.html Now, even though sssd watches the passwd and group files with the help of inotify, there can still be a small window where someone requests a user or a group, finds that it doesn't exist, adds the entry and checks again. Without some support in shadow-utils that would explicitly drop the sssd caches, the inotify watch can fire a little late, so a combination of commands like this: getent passwd user || useradd user; getent passwd user can result in the second getent passwd not finding the newly added user as the racy behaviour might still return the cached negative hit from the first getent passwd. This patch more or less copies the already existing support that shadow-utils had for dropping nscd caches, except using the "sss_cache" tool that sssd ships.
