2013-12-23bus: when getting a kdbus connection into a container wait first for child, ↵Lennart Poettering
then read message There's no EOF generated for AF_UNIX/SOCK_DGRAM sockets, hence let's wait for the child first to see if it succeeded, only then read the socket.

instead

2013-12-23bus: switch kdbus bloom filter over to SipHash (from MurmurHash3)Lennart Poettering
Let's try to standardize on a single non-cryptographic hash algorithm, and for that SipHash appears to be the best answer. With this change there are two other hash functions left in systemd: an older version of MurmurHash embedded into libudev for the bloom filters in udev messages (which is hard to update, given that the we probably should stay compatible with older versions of the library). And lookup3 in the journal files (which we could replace for new files, but which is probably not worth the work).

Units from user services underneath user@.service would not be detected properly.
2013-12-22shared: switch our hash table implementation over to SipHashLennart Poettering
SipHash appears to be the new gold standard for hashing smaller strings for hashtables these days, so let's make use of it.

2013-12-21util: replace readdir_r with readdirFlorian Weimer
This fixes rm_rf_children_dangerous to detect errors during directory reading. Previously, it could dereference an uninitialized pointer.
2013-12-21install: replace readdir_r with readdirFlorian Weimer
The old code incorrectly assumed that readdir_r updates errno.

2013-12-20logging: reduce send timeout to something more sensibleZbigniew Jędrzejewski-Szmek
For a user, the timeout of 1 min per message seems equivalent to a hang. If journald cannot process a message from PID1 for 10 ms then something is significantly wrong. It's better to lose the message and continue.

2013-12-18Revert "ptyfwd: make master terminal attributes raw, too"Lennart Poettering
This reverts commit e7d43b3cc30764138c90eaaf95d3d8f49e448890. This broke the console terminal when booting up a container, so let's not do this.

2013-12-18log: don't reopen /dev/console each time we call log_open()Lennart Poettering
Instead, force reopen it only if we really really have to.
2013-12-18service: watch main pid even in final statesLennart Poettering
In some circumstances, for example when start-up times out we immediately jump into the final state, at which point we still should try to watch the main pid so that the SIGCHLD allows us to quickly move into dead state.
2013-12-18busctl: output a single sorted list of names, including activatable and ↵Lennart Poettering

2013-12-17_noreturn_ --> noreturn for C11 compatShawn Landden
also define noreturn w/o <stdnoreturn.h>
2013-12-17util: no need for in_initrd() cache to be thread-localShawn Landden
the process only has one working directory, and a race is harmless
2013-12-17__thread --> thread_local for C11 compatShawn Landden
Also make thread_local available w/o including <threads.h>. (as the latter hasn't been implemented, but this part is trivial)
2013-12-17libsystemd-bus: true/false instead of yes/no in msg dumpLukasz Skalski
Due to this patch, message dump (for message which includes boolean type) is more consistent with dbus-send (which display true/false instead of yes/no for boolean). It's only simple 'cosmetics change'. ** For dbus-send ** dbus-send --system --dest=org.freedesktop.DBus --type=method_call --print-reply / org.freedesktop.DBus.NameHasOwner string:org.freedesktop.login1 method return sender=org.freedesktop.DBus -> dest=:1.97 reply_serial=2 boolean true ** For libsystemd-bus (without this patch) ** ‣ Type=method_call Endian=l Flags=0 Version=2 Serial=8 Destination=org.freedesktop.DBus Path=/org/freedesktop/DBus Interface=org.freedesktop.DBus Member=NameHasOwner MESSAGE "s" { STRING "org.freedesktop.login1"; }; ‣ Type=method_return Endian=l Flags=1 Version=2 Serial=51 ReplySerial=8 Sender=:1.59 Destination=:1.67 UniqueName=:1.59 WellKnownNames={org.freedesktop.DBus} MESSAGE "b" { BOOLEAN yes; }; For me true/false seems to be better readable than yes/no for BOOLEAN.

2013-12-17bus: when entering an existing namespace to connect to a container's system ↵Lennart Poettering
bus also switch over PID namespace This is necessary to ensure that kdbus can collect creds of the destination namespace when connecting.
2013-12-16util: try harder to increase the send/recv buffers of socketsLennart Poettering
If we have the priviliges we will try SO_SNDBUFFORCE/SO_RCVBUFFORCE and only fall back to SO_SNDBUF/SO_RCVBUF if that fails.
2013-12-16core: refuse doing %h, %s, %U specifier resolving in PID 1Lennart Poettering
These specifiers require NSS lookups to work, and we really shouldn't do them from PID 1 hence. With this change they are now only supported for user systemd instance, or when the configured user for a unit is root.
2013-12-15Fix a few signed/unsigned format string issuesZbigniew Jędrzejewski-Szmek

the transition
2013-12-14bus: when connecting to a container's kdbus instance, enter namespace firstLennart Poettering
Previously we'd open the connection in the originating namespace, which meant most peers of the bus would not be able to make sense of the PID/UID/... identity of us since we didn't exist in the namespace they run in. However they require this identity for privilege decisions, hence disallowing access to anything from the host. Instead, when connecting to a container, create a temporary subprocess, make it join the container's namespace and then connect from there to the kdbus instance. This is similar to how we do it for socket conections already. THis also unifies the namespacing code used by machinectl and the bus APIs.

2013-12-11journal: add ability to browse journals of running OS containersLennart Poettering
This adds the new library call sd_journal_open_container() and a new "-M" switch to journalctl. Particular care is taken that journalctl's "-b" switch resolves to the current boot ID of the container, not the host.

2013-12-11ptyfwd: Don't set the output prop of stdin, nor the input props of stdout.Luke Shumaker
It was calling cfmakeraw(3) on the properties for STDIN_FILENO; cfmakeraw sets both input and output properties. If (and only if) stdin and stdout are the same device is this correct. Otherwise, we must change only the input properties of stdin, and only the output properties of stdout.

2013-12-06Get rid of our reimplementation of basenameZbigniew Jędrzejewski-Szmek
The only problem is that libgen.h #defines basename to point to it's own broken implementation instead of the GNU one. This can be fixed by #undefining basename.
