Fix issue where IN6_ADDR_GEN_MODE_STABLE_PRIVACY is undefined but
IFLA_INET6_ADDR_GEN_MODE is defined and thus the former does not get
fixed in missing.h. This occurs with kernel headers new enough to have
the IFLA_INET6_ADDR_GEN_MODE but old enough to not yet have
IN6_ADDR_GEN_MODE_STABLE_PRIVACY (e.g. 3.18).

This reworks "systemctl status" and "systemctl show" a bit. It removes the
definition of the `property_info` structure, because we can simply reuse the
existing UnitStatusInfo type for that.
The "could not be found" message is now printed by show_one() itself (and not
its caller), so that it is shown regardless by who the function is called.
(This makes it necessary to pass the unit name to the function.)
This also adds all properties found to a set, and then checks if any of the
properties passed via "--property=" is mising in it, if so, a proper error is
generated.
Support for checking the PID file of a unit is removed, as this cannot be done
reasonably client side (since the systemd instance we are talking to might sit
on another host)

Syscall filter fixes, tighter nspawn seccomp sandbox by default
|
|
Typing `rd.rescue` is easier than `rd.systemd.unit=rescue.target`.
|
|
More verbose logging in localed, unit tests, and a few tweaks to keymap conversions
|
|
Let's block access to the kernel keyring and a number of obsolete system calls.
Also, update list of syscalls that may alter the system clock, and do raw IO
access. Filter ptrace() if CAP_SYS_PTRACE is not passed to the container and
acct() if CAP_SYS_PACCT is not passed.
This also changes things so that kexec(), some profiling calls, the swap calls
and quotactl() is never available to containers, not even if CAP_SYS_ADMIN is
passed. After all we currently permit CAP_SYS_ADMIN to containers by default,
but these calls should not be available, even then.

This adds three new seccomp syscall groups: @keyring for kernel keyring access,
@cpu-emulation for CPU emulation features, for exampe vm86() for dosemu and
suchlike, and @debug for ptrace() and related calls.
Also, the @clock group is updated with more syscalls that alter the system
clock. capset() is added to @privileged, and pciconfig_iobase() is added to
@raw-io.
Finally, @obsolete is a cleaned up. A number of syscalls that never existed on
Linux and have no number assigned on any architecture are removed, as they only
exist in the man pages and other operating sytems, but not in code at all.
create_module() is moved from @module to @obsolete, as it is an obsolete system
call. mem_getpolicy() is removed from the @obsolete list, as it is not
obsolete, but simply a NUMA API.

safe_atou32 (#3522)

Move the merger of environment variables before setting up the PAM
session and pass the aggregate environment to PAM setup. This allows
control over the PAM session hooks through environment variables.
PAM session initiation may update the environment. On successful
initiation of a PAM session, we adopt the environment of the
PAM context.
|
|
... as well as halt/poweroff/kexec/suspend/hibernate/hybrid-sleep.
Running those commands will fail in user mode, but we try to set the wall
message first, which might even succeed for privileged users. Best to nip
the whole sequence in the bud.

Our functions that query /proc/pid/ support using pid==0 to mean
self. get_process_id also seemed to support that, but it was not implemented
correctly: the result should be in *uid, not returned, and also it gave
completely bogus result when called from get_process_gid(). But afaict,
get_process_{uid,gid} were never called with pid==0, so it's not an actual
bug. Remove the broken code to avoid confusion.
|
|
This makes it easy to test the query code on "ssh localhost"
and similar.
|
|
This fixes a bunch of copy&paste errors in the output.
|
|
If max_length is equal or greater than cmdline length all trailing non-printable
characters are dropped. If max_length is 0 it should do the same.
This should also fix cmdline truncation if the last character is not '\0'.
Fixes #3469.
