Use sendfile smarter

systemd: obey systemd.log_color config

core: look for instance when processing template name
|
|
We have a bunch of syscall wrapper definitions and it's easier to
see that they follow the same pattern if they are not interspersed
with other defines.
Change the wrappers to be uniform:
- if __NR_XXX is not defined, do not bother to call the syscall,
and return -1/ENOSYS immediately.
- do not check __NR_XXX defines if we detect the symbol as defined,
since we don't need them anyway
- reindent stuff for readability
New file basic/missing_syscall.h is included at the end of missing.h
because it might make use of some of the definitions in missing.h.

For btrfs, c_f_r() is like BTRFS_IOC_CLONE which we already used, but also
works when max_bytes is set. We do call copy_bytes in coredump code with
max_bytes set, and for large files, so we might see some benefit from using
c_f_r() on btrfs.
For other filesystems, c_f_r() falls back to do_splice_direct(), the same as
sendfile, which we already call, so there shouldn't be much difference.
Tested with test-copy and systemd-coredump on Linux 4.3 (w/o c_f_r)
and 4.5 (w/ c_f_r).

syscall numbers based on:

|
rules: allow users to access frame buffer devices
|
|
Clang warnings
|
|
units: run ldconfig.service after we have mounted all local file systems
|
|
Also drop ConditionNeedsUpdate=|/etc. Regardless if system is updated
online or offline, updating dynamic loader cache should always be
responsibility of packaging tools/scripts.

Fixes #2845.

For example it allows weston to be started unprivileged.

If first attempt to merge units failed and we are trying to do
merge the other way around and at the same time we are working with
template name, then other unit can't possibly be template, because it is
not possible to have template unit running, only instances of the
template. Thus we need to look for already active instance instead.

Reference correct `machinectl` command in 219 NEWS
|
|
NEWS for `219` references `machinectl list-images` to describe the introduced clone feature - this looks like a copy'n'paste problem.
Use `machinectl clone` instead.

The attribute was removed in commit c047507 in the clang repository as it
was never properly implemented anyway. Avoid using the attribute with
clang because it generates a ton of annoying warnings.

We called sendfile with 16kb (a.k.a. COPY_BUFFER_SIZE) as the maximum
number of bytes to copy. This seems rather inefficient, especially with
large files. Instead, call sendfile with a "large" maximum.
What "large" max means is a bit tricky: current file offset + max
must fit in loff_t. This means that as we call sendfile more than once,
we have to lower the max size.
With this patch, test-copy calls sendfile twice, e.g.:
sendfile(4, 3, NULL, 9223372036854775807) = 738760
sendfile(4, 3, NULL, 9223372036854037047) = 0
The second call is necessary to determine EOF.
|

I started looking into adding copy_file_range support, and discovered
that we can improve the way we call sendfile:
- sendfile(2) man page is missing an important bit: the number of bytes to
copy cannot be too big (SSIZE_MAX actually), and the description of EINVAL
return code does not mention this either,
- our implementation works but calls sendfile over and over with a small
size, which seems suboptimal.
First add a test which (under strace) can be used to see current behaviour.

It was added in 2.6.39, and causes an assertion to fail when running in mock
hosted on 2.6.23-based RHEL-6:
Assertion 'clock_gettime(map_clock_id(clock_id), &ts) == 0' failed at systemd/src/basic/time-util.c:70, function now(). Aborting.

include sys/sysmacros.h in more places
|
|
Since glibc is moving away from implicitly including sys/sysmacros.h
all the time via sys/types.h, include the header directly in more
places. This seems to cover most makedev/major/minor usage.

man: network - Fix misspelling of "router advertisement"

In some cases we do not have a udev device when setting up a unit
(certainly the code gracefully handles this). However, we do
then go on to compare the path via path_equal which will assert
if a null value is passed in.
See https://bugs.mageia.org/show_bug.cgi?id=17766
Not sure if this is the correct fix, but it avoids the crash

Simply avoid the trouble and use a void* if the define
is missing. We lose type safety, but who cares.
sigaction(2) says that siginfo_t requires _POSIX_C_SOURCE >= 199309L,
but we can be a bit more generous and use the same define
as /usr/include/signal.h.
