string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.

- Rely everywhere that we use abs() on the error code passed in anyway,
thus don't need to explicitly negate what we pass in
- Never attach synthetic error number information to log messages. Only
log about errors we *receive* with the error number we got there,
don't log any synthetic error, that don#t even propagate, but just eat
up.
- Be more careful with attaching exactly the error we get, instead of
errno or unrelated errors randomly.
- Fix one occasion where the error number and line number got swapped.
- Make sure we never tape over OOM issues, or inability to resolve
specifiers

NSS plugins might create additional threads. Remove the limit, we cannot
really make any assumptions here.

This fully synchronizes the content of a "make dist" and a "git archive"

This ports a lot of manual code over to sigprocmask_many() and friends.
Also, we now consistly check for sigprocmask() failures with
assert_se(), since the call cannot realistically fail unless there's a
programming error.
Also encloses a few sd_event_add_signal() calls with (void) when we
ignore the return values for it knowingly.

It's only marginally shorter then the usual for() loop, but certainly
more readable.

No functional changes.

For daemons which have a main configuration file, there's
little reason for the administrator to use configuration snippets.
They are useful for packagers which need to override settings, but
we shouldn't advertise that as the main way of configuring those
services.

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

This reverts commit d6d810fbf8071f8510450dbacd1d083f37603656.
It's apparently not OK to pass MSG_CMSG_CLOEXEC to recvmsg() of raw
sockets.

Let's make timesyncd less chatty.

Let's downgrade the statistics output from LOG_INFO to LOG_DEBUG.

This way timesyncd cannot be used to fork().
Note that it generally is not safe to use RLIMIT_NPROC, since it breaks
running the same daemon in multiple containers if they do not use user
namespacing. However, timesyncd is excepted from running in a container
anyway, hence it is safe in this case.

If the received NTP message from server didn't fit to our buffer, either
it is doing something nasty or we don't know the protocol. Consider the
packet as invalid.

In any case, the compiler generates the same code inline and never
actually calls the library function.

If the format string contains %m, clearly errno must have a meaningful
value, so we might as well use log_*_errno to have ERRNO= logged.
Using:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/'
Plus some whitespace, linewrap, and indent adjustments.

|
Using:
find . -name '*.[ch]' | while read f; do perl -i.mmm -e \
'local $/;
local $_=<>;
s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg;
print;'
$f
done
And a couple of manual whitespace fixups.

It corrrectly handles both positive and negative errno values.
|

As a followup to 086891e5c1 "log: add an "error" parameter to all
low-level logging calls and intrdouce log_error_errno() as log calls
that take error numbers", use sed to convert the simple cases to use
the new macros:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/'
Multi-line log_*() invocations are not covered.
And we also should add log_unit_*_errno().

This also makes the source port less predicatable.

Original patch from: Miroslav Lichvar <mlichvar@redhat.com>
|
|
After receiving a reply from the server, allow two missed replies before
switching to another server to avoid unnecessary clock hopping when
packets are getting lost in the network.
|
|
|
|
When all servers are exhausted, wait for one poll interval before trying
to connect again to the first server in the list. Also, keep increasing
the polling interval to make sure a client not getting any valid replies
will not send requests to any server more frequently than is allowed by
the maximum polling interval.

NTPv4 servers don't reply with unsynchronized status when they lost
synchronization, they only keep increasing the root dispersion and it's
up to the client to decide at which point they no longer consider it
synchronized.
Ignore replies with root distance over 5 seconds.
|
|
|
|
The kernel timestamp (recv_time) is made earlier than current time
(now_ts), use the timestamp captured before sending packet directly.

The source file got much too large, hence split up the sources into
multiple per-object files, similar in style to resolved.

are online
This should provide better compatibility with systems that lack networkd
|
|
After all we want to compare a monotonically increasing clock with the
remote clock, hence we shouldn't ignore system suspend periods.
