Subject: [PATCH] sources/files: do not pass floats to --max-time
curl uses strtod from the C standard library to convert the --max-time's value
from string to double. However, this is what strtod expects:
nonempty sequence of decimal digits optionally containing decimal-point
character (as determined by the current C locale)
Yeah, unfortunately, the decimal-point character is determined by the current
C locale. For example, Czech and German locale uses a comma as the
decimal-point character.
For reasons I don't fully understand, Python thinks it's running on en_US
locale, even though LC_NUMERIC is set to cs_CZ, so it uses a full stop as the
decimal-point character when converting float to string. However, as written
before, curl fails to parse this because it expects comma.
The fix I chose is simple: Use math.ceil, so only an integer can be passed to
curl. Why ceil? Because --max-time == 0 sounds fishy. math.ceil should return
an integer (and it does in Python 3.8) but the documentation is not 100% clear
on this topic, so let's be paranoid and also convert it to int after the
ceiling.

Subject: [PATCH] selinux: allow nnp and nosuid transitions
Allow osbuild_t to no_new_privs (nnp) and nosuid domain transition
into setfiles_mac_t and install_t. nnp is a inheritable per-thread
flag (PR_SET_NO_NEW_PRIVS, see prctl(2)), whereby a promise is made
by execve(2) to not grant any new privileges that could not have
been done without the execv call. This is on contrast to what can
be done via SELinux rules, i.e. in our case `setfiles_mac_t` and
`install_t` can set arbitrary SELinux labels, but `osbuild_t`
itself can not; but `osbuild_t` enables the transitioning of
`setfiles_mac_t` for the `setfiles` binary via execve(2) from a
process with `osbuild_t`. Related, the nosuid mount flag, prevents
the suid, sgid bits to be interpreted and thus are in the same
spirit as nnp, i.e. no new privs during execve(2).
Thus SELinux domain transitions stand in contrast with nnp and
nosuid transitions, and have therefore been de-coupled. See also
the corresponding kernel patch at [1] for more information.
bubblewrap (bwrap) in contrast to `systemd-nspawn` always sets the
nnp flag, as well as the nosuid option for all bind-mounts. Since
we no use bwrap to contain processes we need to allow the nnp and
nosuid transitions from `osbuild_t` to `setfiles_mac_t` and
`install_t`.
