5 years agobus-message: introduce two kinds of references to bus messages
Lennart Poettering [Thu, 17 Jan 2019 17:18:54 +0000 (18:18 +0100)]
bus-message: introduce two kinds of references to bus messages

Before this commit bus messages had a single reference count: when it
reached zero the message would be freed. This simple approach meant a
cyclic dependency was typically seen: a message that was enqueued in a
bus connection object would reference the bus connection object but also
itself be referenced by the bus connection object. So far out strategy
to avoid cases like this was: make sure to process the bus connection
regularly so that messages don#t stay queued, and at exit flush/close
the connection so that the message queued would be emptied, and thus the
cyclic dependencies resolved. Im many cases this isn't done properly
however.

With this change, let's address the issue more systematically: let's
break the reference cycle. Specifically, there are now two types of
references to a bus message:

1. A regular one, which keeps both the message and the bus object it is
   associated with pinned.

2. A "queue" reference, which is weaker: it pins the message, but not
   the bus object it is associated with.

The idea is then that regular user handling uses regular references, but
when a message is enqueued on its connection, then this takes a "queue"
reference instead. This then means that a queued message doesn't imply
the connection itself remains pinned, only regular references to the
connection or a message associated with it do. Thus, if we end up in the
situation where a user allocates a bus and a message and enqueues the
latter in the former and drops all refs to both, then this will detect
this case and free both.

Note that this scheme isn't perfect, it only covers references between
messages and the busses they are associated with. If OTOH a bus message
is enqueued on a different bus than it is associated with cyclic deps
cannot be recognized with this simple algorithm, and thus if you enqueue
a message associated with a bus A on a bus B, and another message
associated with bus B on a bus A, a cyclic ref will be in effect and not
be discovered. However, given that this is an exotic case (though one
that happens, consider systemd-bus-stdio-bridge), it should be OK not to
cover with this, and people have to explicit flush all queues on exit in
that case.

Note that this commit only establishes the separate reference counters
per message. A follow-up commit will start making use of this from the
bus connection object.

copy: don't synthesize a 'user.crtime_usec' xattr on copy unless explicitly requested

Previously, when we'd copy an individual file we'd synthesize a
user.crtime_usec xattr with the source's creation time if we can
determine it. As the creation/birth time was until recently not
queriable form userspace this effectively just propagated the same xattr
on the source to the same xattr on the destination. However, current
kernels now allow to query the birthtime using statx() and we do make
use of that now. Which means that suddenly we started synthesizing these
xattrs much more regularly.

Doing this actually does make sense, but only in very few cases:
not for the typical regular files we copy, but certainly when dealing
with disk images. Hence, let's keep this kind of propagation, but let's
make it a flag and default to off. Then turn it on whenever we deal with
disk images, and leave it off otherwise.

This is particularly relevant as overlayfs combining a real fs, and a
tmpfs on top will result in EOPNOTSUPP when it is attempted to open a
file with xattrs for writing, as tmpfs does not support xattrs, and
hence the copy-up cannot work. Hence, let's avoid synthesizing this
needlessly, to increase compat with overlayfs.

Previously, we'd mount the ESP to /efi if that existed and was empty,
falling back to /boot if that existed and was empty.

With this change, the XBOOTLDR partition is mounted to /boot
unconditionally. And the EFI is mounted to /efi if that exists (but it
doesn't have to be empty — after all the name is very indicative of what
this is supposed to be), and to /boot as a fallback but only if it
exists and is empty (we insist on emptiness for that, since it might be
used differently than what we assume).

The net effect is that $BOOT should be reliably found under /boot, and
the ESP is either /efi or /boot.
