Currently socket_address_listen() calls mac_selinux_bind() to bind a UNIX
socket and checks its return value and errno for EADDRINUSE. This is not
correct. When there's an SELinux context change made for the new socket,
bind() is not the last function called in mac_selinux_bind(). In that
case the last call is setfscreatecon() from libselinux which can change
errno as it uses access() to check if /proc/thread-self is available.
It fails on kernels before 3.17 and errno is set to ENOENT.
It's safe to check only the return value at it's set to -errno.

Selinux loading fix and warning cleanups
|
|
It seems that it is signed both on i386 and arm.
Avoids a stupid gcc warning on arm:
src/udev/udevadm-monitor.c: In function ‘print_device’:
src/udev/udevadm-monitor.c:44:16: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 3 has type ‘__time_t {aka long int}’ [-Wformat=]
printf("%-6s[%"PRI_TIME".%06ld] %-8s %s (%s)\n",

As described in the documentation:
When O_PATH is specified in flags, flag bits other than O_CLOEXEC,
O_DIRECTORY, and O_NOFOLLOW are ignored.
So, we can remove unnecessary flags in a case when O_PATH is passed
to the open() or openat().

shorten hostname before checking for trailing dot
|
|
core: avoid compiler warning when compiling with -fexceptions
|
|
Shortening can lead to a hostname that has a trailing dot.
Therefore it should be done before checking from trailing dots.
|
|
Initialize auto variables with cleanup attribute, otherwise we
get a compiler warning with -fexceptions.
./configure CFLAGS='-Wmaybe-uninitialized -fexceptions -O2'

As we default to "hardware clock is in UTC" if /etc/adjtime is not present, it
also makes sense to have that default if /etc/adjtime contains only one or two
lines.
Drop the "gibberish" test case, as this was just EIO because of not containing
three lines, which is already contained in other tests. clock_is_localtime()
never actually validated the format of the first two lines, and there is little
point in doing that.
This addresses the reading half of issue #2638.
|
|
Add path argument to clock_is_localtime() and default to "/etc/adjtime" if it's
NULL. This makes the function testable.
Add test-clock: initial test cases for some scenarios, using a temporary file.
This also checks the behaviour with a NULL (i. e. the system's /etc/adjtime)
file.

tree-wide: minor formatting inconsistency cleanups

Bugfix set virt=none when running on XEN Dom0
|
|
When running in XEN Dom0 the virtualization check:
1) detect_xen returns HYPERVISOR_NONE so next checks are executed
2) /proc/sys/hypervisor detects a XEN hypervisor
it is lacking the special Dom0 detection as in detect_xen
With this patch, at the end of all virtualization checks we double-check if running in XEN Dom0 or DomU.
|
|
print out every single detection executed and its result.

Remove systemd-bootchart

Networkctl prettification

|
|
|
|

This was only needed for bootchart, so it can go now.

tree-wide: make ++/-- usage consistent WRT spacing
|
|
Throughout the tree there's spurious use of spaces separating ++ and --
operators from their respective operands. Make ++ and -- operator
consistent with the majority of existing uses; discard the spaces.

When a transaction is complete, and we notify its owners, make sure we deal
correctly with the requesters removing themselves from the list of owners while
we continue iterating.
This was previously already dealt with with transactions that require other
transactions for DNSSEC purposes, fix this for other possibly transaction
owners too now.
Since iterating through "Set" objects is not safe regarding removal of entries
from it, rework the logic to use two Sets, and move each entry we notified from
one set to the other set before we dispatch the notification. This move operation
requires no additional memory, and enables us to ensure that we don't notify
any object twice.
Fixes: #2676

As suggested by CODING_STYLE we should use "void*" as type for generic memory,
and uint8_t* for generic bytes. Hence use that instead of "char*", which should
really be used only for strings these days.

We have this ids, hence let's use them universally.
|
|
After all, it is pretty generic, has no external deps besides libc, and is very
similar to virt.[ch] which is also in basic/

calendarspec: fix find_next skipping times

missing.h: Explicitly check for IFLA_BRPORT_PROXYARP
|
|
reset usec when bumping hours/minutes
|
|
RHEL explicitly disables IFLA_BRPORT_PROXYARP by renaming the enum value.
In order to support unpatched builds, we have two options:
a) redefine the enum value through missing.h and ignore the fact that it
is really unsupported, or
b) omit that enum value on rtnl_prot_info_bridge_port_types[]
As we are not actually using this netlink type anywhere, and because it
is only hooked up for the sake of completeness, this patch opts for the
former.

A fix for #2678
|
|
Make sure we propagate errors properly.
|
|
normalization success
After all, we verify that every calendar part is not out of bounds later on,
and it's fully OK if the normalization has no effect.
|
|
Let's add some minimalistic LLDP sender support. The idea is that this is
either on or off, and all fields determined automatically rather than
configured explicitly.

Let's not get confused should we be connected to some bridge that mirrors back
our packets.

CID #1320855.
|
|
Usually, we place the #pragma once before the copyright blurb in header files,
but in a few cases we didn't. Move those around, so that we do the same thing
everywhere.
|
|
After all, most ETHERTYPE variables are defined in the system headers, hence
define these where we defined all other fill-ins for system headers.

Coverity fixes

This is a cosmetic best-effort thing anyway.

Include and internal struct member fixes.
