2015-12-02tests: turn check if manager cannot be intialized into macroZbigniew Jędrzejewski-Szmek
We need to check the same thing in multiple tests. Use a shared macro to make it easier to update the list of errnos. Change the errno code for "unitialized cgroup fs" for ENOMEDIUM. Exec format error looks like something more serious. This fixes test-execute invocation in mock.

2015-11-28acl-util: only set the mask if not presentZbigniew Jędrzejewski-Szmek
When we have non-owner user or group entries, we need the mask for the acl to be valid. But acl_calc_mask() calculates the mask to include all permissions, even those that were masked before. Apparently this happens when we inherit *:r-x permissions from a parent directory — the kernel sets *:r-x, mask:r--, effectively masking the executable bit. acl_calc_mask() would set the mask:r-x, effectively enabling the bit. To avoid this, be more conservative when to add the mask entry: first iterate over all entries, and do nothing if a mask. This returns the code closer to J.A.Steffens' original version in v204-90-g23ad4dd884. Should fix https://github.com/systemd/systemd/issues/1977.
2015-11-28test-acl-util: add new testZbigniew Jędrzejewski-Szmek
For now, only add_acls_for_user is tested. When run under root, it actually sets the acls. When run under non-root, it sets the acls for the user, which does nothing, but at least calls the functions.
2015-11-27journal: move the gist of server_fix_perms to acl-util.[hc]Zbigniew Jędrzejewski-Szmek
Most of the function is moved to acl-util.c to make it possible to add tests in subsequent commit. Setting of the mode in server_fix_perms is removed: - we either just created the file ourselves, and the permission be better right, - or the file was already there, and we should not modify the permissions. server_fix_perms is renamed to server_fix_acls to better reflect new meaning, and made static because it is only used in one file.
2015-11-27libsystemd: make sure we prefix even the dirty secrets in our API with "_sd_"Lennart Poettering
This renames __useless_struct_to_allow_trailing_semicolon__ everywhere to _sd_useless_struct_to_allow_trailing_semicolon_, to follow our usual rule of prefixing stuff from public headers that should be considered internal with "_sd_". While we are at it, also to be safe: when the struct is used in the C++ protector macros make sure to use two different names depending on whether it appears in the C++ or C side of things. After all, there might be compilers that don't consider C++ and C structs the same. See https://github.com/systemd/systemd/pull/2052#discussion_r46067059
2015-11-27selinux: split up mac_selinux_have() from mac_selinux_use()Lennart Poettering
Let's distuingish the cases where our code takes an active role in selinux management, or just passively reports whatever selinux properties are set. mac_selinux_have() now checks whether selinux is around for the passive stuff, and mac_selinux_use() for the active stuff. The latter checks the former, plus also checks UID == 0, under the assumption that only when we run priviliged selinux management really makes sense. Fixes: #1941

2015-11-27util-lib: move nss-util.h from shared/ to basic/Lennart Poettering
The header file defines some helpers for GLIBC NSS and doesn't include anything else but glibc headers, hence there's little reason to keep it in shared/. See: #2008
2015-11-27tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easyLennart Poettering
GLIB has recently started to officially support the gcc cleanup attribute in its public API, hence let's do the same for our APIs. With this patch we'll define an xyz_unrefp() call for each public xyz_unref() call, to make it easy to use inside a __attribute__((cleanup())) expression. Then, all code is ported over to make use of this. The new calls are also documented in the man pages, with examples how to use them (well, I only added docs where the _unref() call itself already had docs, and the examples, only cover sd_bus_unrefp() and sd_event_unrefp()). This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we tend to call our destructors these days. Note that this defines no public macro that wraps gcc's attribute and makes it easier to use. While I think it's our duty in the library to make our stuff easy to use, I figure it's not our duty to make gcc's own features easy to use on its own. Most likely, client code which wants to make use of this should define its own: #define _cleanup_(function) __attribute__((cleanup(function))) Or similar, to make the gcc feature easier to use. Making this logic public has the benefit that we can remove three header files whose only purpose was to define these functions internally. See #2008.

If pid < 0 after fork(), 0 is always returned because r = exec_context_load_environment() has exited successfully. This will make the caller of exec_spawn() not able to handle the fork() error case and make systemd abort assert() possibly.

2015-11-27resolved: announce support for large UDP packetsTom Gundersen
This is often needed for proper DNSSEC support, and even to handle AAAA records without falling back to TCP. If the path between the client and server is fully compliant, this should always work, however, that is not the case, and overlarge packets will get mysteriously lost in some cases. For that reason, we use a similar fallback mechanism as we do for palin EDNS0, EDNS0+DO, etc.: The large UDP size feature is different from the other supported feature, as we cannot simply verify that it works based on receiving a reply (as the server will usually send us much smaller packets than what we claim to support, so simply receiving a reply does not mean much). For that reason, we keep track of the largest UDP packet we ever received, as this is the smallest known good size (defaulting to the standard 512 bytes). If announcing the default large size of 4096 fails (in the same way as the other features), we fall back to the known good size. The same logic of retrying after a grace-period applies.
2015-11-27resolved: set the DNSSEC OK (DO) flagTom Gundersen
This indicates that we can handle DNSSEC records (per RFC3225), even if all we do is silently drop them. This feature requires EDNS0 support. As we do not yet support larger UDP packets, this feature increases the risk of getting truncated packets. Similarly to how we fall back to plain UDP if EDNS0 fails, we will fall back to plain EDNS0 if EDNS0+DO fails (with the same logic of remembering success and retrying after a grace period after failure).
2015-11-27resolved: implement minimal EDNS0 supportTom Gundersen
This is a minimal implementation of RFC6891. Only default values are used, so in reality this will be a noop. EDNS0 support is dependent on the current server's feature level, so appending the OPT pseudo RR is done when the packet is emitted, rather than when it is assembled. To handle different feature levels on retransmission, we strip off the OPT RR again after sending the packet. Similarly, to how we fall back to TCP if UDP fails, we fall back to plain UDP if EDNS0 fails (but if EDNS0 ever succeeded we never fall back again, and after a timeout we will retry EDNS0).
2015-11-27resolved: rr - add OPT pseudo-rr supportTom Gundersen
Needed for EDNS0.
2015-11-27resolved: degrade the feature level on explicit failureTom Gundersen
Previously, we would only degrade on packet loss, but when adding EDNS0 support, we also have to handle the case where the server replies with an explicit error.
