Change-Id: I3755e1c75771220c74fe8ae5de1a7d90f2376635 Signed-off-by: Giacomo Leidi <goodoldpaul@autistici.org> Signed-off-by: Ludovic Courtès <ludo@gnu.org> Giacomo Leidi 2024-12-18accounts: Add /etc/subid and /etc/subgid allocation logic....This commit adds allocation logic for subid ranges. Subid ranges are ranges of contiguous subids that are mapped to a user in the host system. This patch implements a flexible allocation algorithm allowing users that do not want (or need) to specify details of the subid ranges that they are requesting to avoid doing so, while upholding requests of users that need to have specific ranges. * gnu/build/accounts.scm (%subordinate-id-min): New variable; (%subordinate-id-max): new variable; (%subordinate-id-count): new variable; (subordinate-id?): new variable; (&subordinate-id-error): new variable; (&subordinate-id-overflow-error): new variable; (&illegal-subid-range-error): new variable; (&specific-subid-range-expected-error): new variable; (&generic-subid-range-expected-error): new variable; (within-interval?): new variable; (allocate-unused-range): new variable; (allocate-generic-range): new variable; (allocate-specific-range): new variable; (reserve-subids): new variable; (range->entry): new variable; (entry->range): new variable; (allocate-subids): new variable; (subuid+subgid-databases): new variable. * gnu/system/accounts.scm (subid-range-end): New variable; (subid-range-has-start?): new variable; (subid-range-less): new variable. * test/accounts.scm: Test them. Change-Id: I8de1fd7cfe508b9c76408064d6f498471da0752d Co-Authored-By: Ludovic Courtès <ludo@gnu.org> Signed-off-by: Giacomo Leidi <goodoldpaul@autistici.org> Signed-off-by: Ludovic Courtès <ludo@gnu.org> Giacomo Leidi 2024-12-18accounts: Add /etc/subuid and /etc/subgid support....This commit adds a new record type, <subid-entry> and serializers and deserializers for it in (gnu build accounts). Each instance of this record represents one line in either /etc/subuid or /etc/subgid. Since Shadow uses the same representation for both files, it should be ok if we do it as well. This commit adds also <subid-range>, a user facing representation of <subid-entry>. It is supposed to be usable directly in OS configurations. * gnu/build/accounts.scm (subid-entry): New record; (write-subgid): add serializer for subgids; (write-subuid): add serializer for subuids; (read-subgid): add serializer for subgids; (read-subuid): add serializer for subuids. * gnu/system/accounts.scm (subid-range): New record. * test/accounts.scm: Test them.
