установить сопоставление gid пространства имен пользователя (set the gid mapping of a user namespace)
Имя (Name)
newgidmap - set the gid mapping of a user namespace
Синопсис (Synopsis)
newgidmap
pid gid lowergid count [gid lowergid count [ ... ]]
Описание (Description)
The newgidmap
sets /proc/[pid]/gid_map based on its command line
arguments and the gids allowed. Subgid delegation can either be
managed via /etc/subgid or through the configured NSS subid
module. These options are mutually exclusive.
Note that the root group is not exempted from the requirement for
a valid /etc/subgid entry.
After the pid argument, newgidmap
expects sets of 3 integers:
gid
Beginning of the range of GIDs inside the user namespace.
lowergid
Beginning of the range of GIDs outside the user namespace.
count
Length of the ranges (both inside and outside the user
namespace).
newgidmap
verifies that the caller is the owner of the process
indicated by pid
and that for each of the above sets, each of the
GIDs in the range [lowergid, lowergid+count) is allowed to the
caller according to /etc/subgid before setting
/proc/[pid]/gid_map.
Note that newgidmap may be used only once for a given process.
Параметры (Options)
