Hello !

The following patchset adds the user namespace and a new syscall execns.

The user namespace will allow a process to unshare its user_struct table,
resetting at the same time its own user_struct and all the associated
accounting.

The purpose of execns is to make sure that a process unsharing a namespace
is free from any reference in the previous namespace. the execve() semantic
seems to be the best candidate as it already flushes the previous process
context.

Thanks for reviewing, sharing, flaming !


I would like give a strong objection to the naming. The -ve() suffix in execve() isn't jettisonable; it indicates its position within a family of functions (only one of which is a true system call.)

execven() would be better name (the -n argument coming after then -e argument). The library could then provide execlen(), execlpn() etc as appropriate.
