That way, if the test directory does not exist we don't leave behind
temporary files (as in that case or on test failure the cleanup actions
don't run).

|
When trying to directly run a test executable in the build tree without
setting $TEST_DIR, some tests fail with a non-obvious error message.
Print an useful one instead.

A bug exists where the conflict counter is cleared
regardless of whether or not the next probe attempt leads to
a successful address acquisition. This causes 'bursts' of
MAX_CONFLICTS probes followed by a delay of
RATE_LIMIT_INTERVAL instead of a single probe each
RATE_LIMIT_INTERVAL when beyond MAX_CONFLICTS.
The conflict counter should only be cleared after an
address is successfully acquired. This commit achieves that
goal.
From RFC3927:
A host should maintain a counter of the number of address
conflicts it has experienced in the process of trying to
acquire an address, and if the number of conflicts exceeds
MAX_CONFLICTS then the host MUST limit the rate at which it
probes for new addresses to no more than one new address per
RATE_LIMIT_INTERVAL. This is to prevent catastrophic ARP
storms in pathological failure cases, such as a rogue host
that answers all ARP probes, causing legitimate hosts to go
into an infinite loop attempting to select a usable address.

The correct error code to report when a provided buffer is too small is
ERANGE. This is recognized by glibc, which will then try again with a
larger buffer. The old behaviour of reporting ENOMEM has no special
meaning for glibc. The error will simply be propagated to the
application, and a later retry will trigger the same error again.
Additionally, h_errnop must be set to NETDB_INTERNAL to have glibc look
at errnop for details.

This breaks again, this time for setups where Qemu is not reported via DMI for whatever
reason. So swap order of cpuid and dmi again, but properly detect oracle.
See issue #5318.

Embedding sd_id128_t's in constant strings was rather cumbersome. We had
SD_ID128_CONST_STR which returned a const char[], but it had two problems:
- it wasn't possible to statically concatanate this array with a normal string
- gcc wasn't really able to optimize this, and generated code to perform the
"conversion" at runtime.
Because of this, even our own code in coredumpctl wasn't using
SD_ID128_CONST_STR.
Add a new macro to generate a constant string: SD_ID128_MAKE_STR.
It is not as elegant as SD_ID128_CONST_STR, because it requires a repetition
of the numbers, but in practice it is more convenient to use, and allows gcc
to generate smarter code:
$ size .libs/systemd{,-logind,-journald}{.old,}
text data bss dec hex filename
1265204 149564 4808 1419576 15a938 .libs/systemd.old

146391 4984 34 151409 24f71 .libs/systemd-journald
It is also much easier to check if a certain binary uses a certain MESSAGE_ID:

The entry must be a single entry in the journal export format, including the
terminating double newline. The MESSAGE field is now generated on the sender
side.
The advantage is that the reporter can easily pass additional metadata.
Continuing with the example of the python excepthook:
COREDUMP_PYTHON_EXECUTABLE=/usr/bin/python3
COREDUMP_PYTHON_VERSION=3.5.2 (default, Sep 14 2016, 11:28:32)

One consideration is whether to use the Journal Export Format, or send packets
over a UNIX socket instead. The advantage of current solution is that although
parsing is more complicated on the receiver side, it is much easier to use on the
sender side. I hope this can be used by various languages for which writing
binary structures to a UNIX socket is harder and more likely to be done wrong
than piping of a simple textyish format.

Only one test case is added, but it is enough to check basic sanity of the
code (single-line and binary fields and trusted fields, allocation and freeing).
|

No functional change.

This is useful for example for Python progams. By installing a python
sys.execepthook we can store the backtrace in the journal. We gather the
backtrace in the python process, and call systemd-coredump to attach additional
fields (COREDUMP_COMM, COREDUMP_EXE, COREDUMP_UNIT, COREDUMP_USER_UNIT,
COREDUMP_OWNER_UID, COREDUMP_SLICE, COREDUMP_CMDLINE, COREDUMP_CGROUP,
COREDUMP_OPEN_FDS, COREDUMP_PROC_STATUS, COREDUMP_PROC_MAPS,
COREDUMP_PROC_LIMITS, COREDUMP_PROC_MOUNTINFO, COREDUMP_CWD, COREDUMP_ROOT,
COREDUMP_ENVIRON, COREDUMP_CONTAINER_CMDLINE). This could also be done in the
python process, but doing this in systemd-coredump saves quite a bit of
duplicate work and unifies the handling of various tricky fields like
COREDUMP_CONTAINER_CMDLINE in one place.
(Of course this applies to any other language which does not dump cores
but wants to log a traceback, e.g. ruby.)

Various stack allocations are changed to use the heap. This might be minimally
slower, but probably doesn't matter. The upside is that we will now properly
free all memory that is allocated.

In commit 050e65a we swapped order of detect_vm_{cpuid,dmi}(). That
fixed Virtualbox but broke qemu with kvm, which is expected to return
'kvm'. So check for qemu/kvm first, then DMI, CPUID last.
This fixes #5318.

start operation of a unit
Let's make sure we verify that all BindsTo= are in order before we actually go
and dispatch a start operation to a unit. Normally the job queue should already
have made sure all deps are in order, but this might not have been sufficient
in two cases: a) when the user changes deps during runtime and reloads the
daemon, and b) when the user placed BindsTo= dependencies without matching
After= dependencies, so that we don't actually wait for the bound to unit to be
up before upping also the binding unit.
See: #4725

This restores behaviour of 53fda2bb933694c9bdb1bbf1f5583e39673b74b2: for
mDNS (and mDNS only) we'll match replies to transactions honouring ANY
matches.

The array doesn't grow dynamically, hence pick the right size at the
moment of allocation. Let's simply multiply the number of addresses of
this link by 2, as that's how many RRs we maintain for it.

test: make unit tests relocatable and add an "install-tests" make target
|
|
Commit ae3251851 changed the fprintf() format argument into a variable
which triggers a gcc 6.3 warning/error:
src/fstab-generator/fstab-generator.c:243:17: error: format not a string literal,
argument types not checked [-Werror=format-nonliteral]
fprintf(f, format, res);
This is a false positive, as the function is only being called with
constant (not user-definable) arguments which are valid format strings.

It is useful to package test-* binaries and run them as root under
autopkgtest or manually on particular machines. They currently have a
built-in hardcoded absolute path to their test data, which does not work
when running the test programs from any other path than the original
build directory.
By default, make the tests look for their data in
<test_exe_directory>/testdata/ so that they can be called from any
directory (provided that the corresponding test data is installed
correctly). As we don't have a fixed static path in the build tree (as
build and source tree are independent), set $TEST_DIR with "make check"
to point to <srcdir>/test/, as we previously did with an automake
variable.
|
|
Moe test-resolve's test data from src/resolve/test-data to
test/test-resolve/ to be consistent with test/test-{execute,path}/. This
will make it easier to make the tests relocatable.

Currently fstab entries with 'nofail' option are mounted
asynchronously and there is no way how to specify dependencies
between such fstab entry and another units. It means that
users are forced to write additional dependency units manually.
The patch introduces new systemd fstab options:
x-systemd.before=<PATH>
x-systemd.after=<PATH>
- to specify another mount dependency (PATH is translated to unit name)
x-systemd.before=<UNIT>
x-systemd.after=<UNIT>
- to specify arbitrary UNIT dependency
For example mount where A should be mounted before local-fs.target unit:
/dev/sdb1 /mnt/test/A none nofail,x-systemd.before=local-fs.target

We don't actually make use of the return value for now, but it matches
our coding style elsewhere, and it actually shortens our code quite a
bit.
Also, add a missing OOM check after dns_answer_new().
|
|
This becomes handy later on. Moreover, we keep track of similar counters
for other objects like this too, hence adding this here too is obvious.
|
|
This reverts a part of 53fda2bb933694c9bdb1bbf1f5583e39673b74b2:
On classic DNS and LLMNR ANY requests may be replied to with any kind of
RR, and the reply does not have to be comprehensive: these protocols
simply define that if there's an RRset that can answer the question,
then at least one should be sent as reply, but not necessarily all. This
means it's not safe to "merge" transactions for arbitrary RR types into
ANY requests, as the reply might not answer the specific question.
As the merging is primarily an optimization, let's undo this for now.
This logic may be readded later, in a way that only applies to mDNS.
Also, there's an OOM problem with this chunk: dns_resource_key_new()
might fail due to OOM and this is not handled. (This is easily removed
though, by using DNS_RESOURCE_KEY_CONST()).

src/core/dbus.c: In function 'find_unit':

At -O3, this was printed a hundred times for various callers of
manager_add_job_by_name(). AFAICT, there is no error and `unit` is always
intialized. Nevertheless, add explicit initialization to silence the noise.
src/core/manager.c: In function 'manager_start_target':
src/core/manager.c:1413:16: warning: 'unit' may be used uninitialized in this function [-Wmaybe-uninitialized]

We were inconsistent, manager_load_unit_prepare() would crash if _ret was ever NULL.
But none of the callers use NULL. So simplify things and require it to be non-NULL.

PermissionsStartOnly= (#5309)
ReadOnlyPaths=, ProtectHome=, InaccessiblePaths= and ProtectSystem= are
about restricting access and little more, hence they should be disabled
if PermissionsStartOnly= is used or ExecStart= lines are prefixed with a
"+". Do that.
(Note that we will still create namespaces and stuff, since that's about
a lot more than just permissions. We'll simply disable the effect of
the four options mentioned above, but nothing else mount related.)
This also adds a test for this, to ensure this works as intended.
No documentation updates, as the documentation are already vague enough
to support the new behaviour ("If true, the permission-related execution
options…"). We could clarify this further, but I think we might want to
extend the switches' behaviour a bit more in future, hence leave it at
this for now.
