vserver 0.5
Change log
The new vserver package relies on new ability found in the kernel
patch ftp://ftp.solucorp.qc.ca/pub/vserver/diffctx-2.4.11-3. This
patch works with 2.4.12 as well. I have not released pre-compiled ker-
nel for now.
1. Enhancements
1.1. chcontext and reducecap command line option
The two utilities support the new --flag command line option. This is
used to set some flags in the security context. For new the two flags
are:
+ lock
Once set, a security context is locked. It can't request another
security context.
+ sched
This changes the way priority is calculated for processes in a
vserver. The priority is kind of aglomerated. A vserver running 50
active processes will have a same impact on the server as if it was
running a single process (roughly).
All those flags are one-shot. You can set them, you can't unset
them.
1.2. vserver command: S_FLAGS support<
The vserver command supports the new --flag command line option of the
chcontext utility. You encode the flags (lock and sched) in the
vserver configuration (/etc/vservers/confname.conf) like this
S_FLAGS="lock sched"
By default, all new vserver are created with S_FLAGS="lock".
