Date: Thu, 28 Jun 2018 16:09:04 +0900
Subject: [PATCH] meson: do not compare objects of different types
This fixes the following warning:
```
meson.build:1140: WARNING: Trying to compare values of different types (DependencyHolder, list) using !=.
The result of this is undefined and will become a hard error in a future Meson release.
```
Follow-up for f02582f69fe1e7663a87ba80bd4f90d5d23ee75f(#9410).
(cherry picked from commit 48f5da19b6e8f0d05f5217bc9856093d354ce5d0)

From: Frantisek Sumsal <frantisek@sumsal.cz>

Subject: [PATCH] ci: replace LGTM with CodeQL
As LGTM is going to be shut down by EOY, let's use CodeQL instead.
This is loosely based on upstream's CodeQL configs with some minor
tweaks to avoid backporting tons of unrelated commits.

Subject: [PATCH] sysctl: downgrade message when we have no permission
We need to run sysctl also in containers, because the network
subtree is namespaces and may legitimately be writable. But logging
all "errors" at notice level creates unwanted noise.
Also downgrade message about missing sysctls to log_info. This might also be
relatively common when configuration is targeted at different kernel
versions. With log_debug it'll still end up in the logs, but isn't really worth
of "notice" most of the time.

On socket creation respect the SELinuxContext= setting of the associated

future process accepting the connection (since w.r.t SELinux sockets
normally have the same label as the owning process).

Subject: [PATCH] manager: use target process context to set socket context
Use target process context to set socket context when using SELinuxContextFromNet
not systemd's context. Currently when using the SELinuxContextFromNet option for
a socket activated services, systemd calls getcon_raw which returns init_t and
uses the resulting context to compute the context to be passed to the
setsockcreatecon call. A socket of type init_t is created and listened on and
this means that SELinux policy cannot be written to control which processes
(SELinux types) can connect to the socket since the ref policy allows all
'types' to connect to sockets of the type init_t. When security accessors see
that any process can connect to a socket this raises serious concerns. I have
spoken with SELinux contributors in person and on the mailing list and the
consensus is that the best solution is to use the target executables context
when computing the sockets context in all cases.
[zjs review/comment:
This removes the branch that was added in 16115b0a7b7cdf08fb38084d857d572d8a9088dc.
16115b0a7b7cdf08fb38084d857d572d8a9088dc did two things: it had the branch here
in 'socket_determine_selinux_label()' and a code in 'exec_child()' to call
'label_get_child_mls_label(socket_fd, command->path, &label)'.
Before this patch, the flow was:
'''
mac_selinux_get_child_mls_label:
peercon = getpeercon_raw(socket_fd);
if (!exec_label)
exec_label = getfilecon_raw(exe);
socket_open_fds:
if (params->selinux_context_net) #
label = mac_selinux_get_our_label(); # this part is removed
else #
label = mac_selinux_get_create_label_from_exe(path);
socket_address_listen_in_cgroup(s, &p->address, label);
exec_child():
exec_context = mac_selinux_get_child_mls_label(fd, executable, context->selinux_context);
setexeccon(exec_context);
'''

Subject: [PATCH] virt: detect Amazon EC2 Nitro instance
Amazon EC2 Nitro hypervisor is technically based on KVM[1], which
systemd-detect-virt identify propely from CPUID. However the lack of
CPUID on aarch64 (A1, T4 instance type) prevents a correct
identification, impacting hostnamectl and systemd-random-seed. Instead
it's possible to identify virtualization from DMI vendor ID.
Prior to this commit:
# hostnamectl

Subject: [PATCH] fileio: introduce read_full_virtual_file() for reading
virtual files in sysfs, procfs
Virtual filesystems such as sysfs or procfs use kernfs, and kernfs can work
with two sorts of virtual files.
One sort uses "seq_file", and the results of the first read are buffered for
the second read. The other sort uses "raw" reads which always go direct to the
device.
In the later case, the content of the virtual file must be retrieved with a
single read otherwise subsequent read might get the new value instead of
finding EOF immediately. That's the reason why the usage of fread(3) is
prohibited in this case as it always performs a second call to read(2) looking
for EOF which is subject to the race described previously.
Fixes: #13585.

Subject: [PATCH] Use BIOS characteristics to distinguish EC2 bare-metal from
VMs
DMI vendor information fields do not provide enough information for us to
distinguish between Amazon EC2 virtual machines and bare-metal instances.
SMBIOS provides a BIOS Information
table (https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.4.0.pdf
Ch. 7) that provides a field to indicate that the current machine is a virtual
machine. On EC2 virtual machine instances, this field is set, while bare-metal
instances leave this unset, so we inspect the field via the kernel's
/sys/firemware/dmi/entries interface.
Fixes #18929

Subject: [PATCH] manager: limit access to private dbus socket
For the system manager, /run/systemd/private is publicly accessible, because
/run/systemd is 0755, and /run/systemd/private is 0777. For the user manager,
/run/user/<uid> is 0700, and /run/user/<uid>/systemd/private is 0777. This
does not directly cause any security issue because we check the sender in
bus_check_peercred (ucred.uid != 0 && ucred.uid != geteuid()).
But it makes sense to limit access to the socket to avoid wasting time in PID1.
Somebody could send messages there that'd we'd reject anyway. It also makes
things more explicit.

Subject: [PATCH] pam: add a call to pam_namespace
A call to pam_namespace is required so that children of user@.service end up in
a namespace as expected. pam_namespace gets called as part of the stack that
creates a session (login, sshd, gdm, etc.) and those processes end up in a
namespace, but it also needs to be called from our stack which is parallel and
descends from pid1 itself.
The call to pam_namespace is similar to the call to pam_keyinit that was added
in ab79099d1684457d040ee7c28b2012e8c1ea9a4f. The pam stack for user@.service
creates a new session which is disconnected from the parent environment. Both
calls are not suitable for inclusion in the shared part of the stack (e.g.
@system-auth on Fedora/RHEL systems), because for example su/sudo/runuser
should not include them.

Subject: [PATCH] virt: Support detection for ARM64 Hyper-V guests
The detection of Microsoft Hyper-V VMs is done by cpuid currently,
however there is no cpuid on ARM64. And since ARM64 is now a supported
architecture for Microsoft Hyper-V guests[1], then use DMI tables to
detect a Hyper-V guest, which is more generic and works for ARM64.

Subject: [PATCH] systemctl: simplify halt_main()
The code at this point is not able to tell whether it was called as
halt/poweroff/reboot or shutdown with time "now".
The code also takes a shortcut to skip logind if called as root.
That however means asking shutdown for immediate action won't trigger a
wall message.
As per https://github.com/systemd/systemd/issues/8424#issuecomment-374677315
all commands should trigger a wall message.
That simplifies the code as we can try logind first always.

Currently, the legacy shutdown commands ignore inhibitors and reboot
immediately if run by root. Let's preserve that behavior in RHEL-8 by
default. The new behavior can be turned on by those who want it by
exporting SYSTEMD_NEW_SHUTDOWN=1 .

Subject: [PATCH] pam_systemd: suppress LOG_DEBUG log messages if debugging is
off
In the PAM module we need to suppress LOG_DEBUG messages manually, if
debug logging is not on, as PAM won't do this for us. We did this
correctly for most log messages already, but two were missing. Let's fix
those too.
Fixes: #10822

Subject: [PATCH] journald: add API to move logging from /var to /run again
We now have this nice little Varlink API, let's beef it up a bit.
[dtardon: This diverges from the upstream commit in two ways: One is
that the new action is bound to a signal, as varlink is not available.
The other is that this introduces a new "flag" file
/run/systemd/journal/relinquished, which is essentially the opposite of
/run/systemd/journal/flushed (hence at most one of them may exist at any
time).]
(cherry picked from commit b4e26d1d8e582d78e67ed766177f10e8e194404c)

Subject: [PATCH] journalctl: add new --relinquish and --smart-relinquish
options
The latter is identical to the former, but becomes a NOP if
/var/log/journal is on the same mount as /, and thus during shutdown
unmounting /var is not necessary and hence we can keep logging until the
very end.
[dtardon: The only divergence from the upstream commit is the impl. of
relinquish_var().]

Subject: [PATCH] pstore: Tool to archive contents of pstore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch introduces the systemd pstore service which will archive the
contents of the Linux persistent storage filesystem, pstore, to other storage,
thus preserving the existing information contained in the pstore, and clearing
pstore storage for future error events.
Linux provides a persistent storage file system, pstore[1], that can store
error records when the kernel dies (or reboots or powers-off). These records in
turn can be referenced to debug kernel problems (currently the kernel stuffs
the tail of the dmesg, which also contains a stack backtrace, into pstore).
The pstore file system supports a variety of backends that map onto persistent
storage, such as the ACPI ERST[2, Section 18.5 Error Serialization] and UEFI
variables[3 Appendix N Common Platform Error Record]. The pstore backends
typically offer a relatively small amount of persistent storage, e.g. 64KiB,
which can quickly fill up and thus prevent subsequent kernel crashes from
recording errors. Thus there is a need to monitor and extract the pstore
contents so that future kernel problems can also record information in the
pstore.
The pstore service is independent of the kdump service. In cloud environments
specifically, host and guest filesystems are on remote filesystems (eg. iSCSI
or NFS), thus kdump relies [implicitly and/or explicitly] upon proper operation
of networking software *and* hardware *and* infrastructure. Thus it may not be
possible to capture a kernel coredump to a file since writes over the network
may not be possible.
The pstore backend, on the other hand, is completely local and provides a path
to store error records which will survive a reboot and aid in post-mortem
debugging.
Usage Notes:
This tool moves files from /sys/fs/pstore into /var/lib/systemd/pstore.
To enable kernel recording of error records into pstore, one must either pass
crash_kexec_post_notifiers[4] to the kernel command line or enable via 'echo Y
> /sys/module/kernel/parameters/crash_kexec_post_notifiers'. This option
invokes the recording of errors into pstore *before* an attempt to kexec/kdump
on a kernel crash.
Optionally, to record reboots and shutdowns in the pstore, one can either pass
the printk.always_kmsg_dump[4] to the kernel command line or enable via 'echo Y >
/sys/module/printk/parameters/always_kmsg_dump'. This option enables code on the
shutdown path to record information via pstore.
This pstore service is a oneshot service. When run, the service invokes
systemd-pstore which is a tool that performs the following:
- reads the pstore.conf configuration file
- collects the lists of files in the pstore (eg. /sys/fs/pstore)
- for certain file types (eg. dmesg) a handler is invoked
- for all other files, the file is moved from pstore
- In the case of dmesg handler, final processing occurs as such:
- files processed in reverse lexigraphical order to faciliate
reconstruction of original dmesg
- the filename is examined to determine which dmesg it is a part
- the file is appended to the reconstructed dmesg
For example, the following pstore contents:
root@vm356:~# ls -al /sys/fs/pstore

Configuration file:
The pstore.conf configuration file has four settings, described below.
- Storage : one of "none", "external", or "journal". With "none", this
tool leaves the contents of pstore untouched. With "external", the
contents of the pstore are moved into the /var/lib/systemd/pstore,
as well as logged into the journal. With "journal", the contents of
the pstore are recorded only in the systemd journal. The default is
"external".
- Unlink : is a boolean. When "true", the default, then files in the
pstore are removed once processed. When "false", processing of the
pstore occurs normally, but the pstore files remain.

+ <title>Description</title>
+ <para><filename>systemd-pstore.service</filename> is a system service that archives the
+ contents of the Linux persistent storage filesystem, pstore, to other storage,
+ thus preserving the existing information contained in the pstore, and clearing
+ pstore storage for future error events.</para>
+
+ <para>Linux provides a persistent storage file system, pstore, that can store
+ error records when the kernel dies (or reboots or powers-off). These records in
+ turn can be referenced to debug kernel problems (currently the kernel stuffs
+ the tail of the dmesg, which also contains a stack backtrace, into pstore).</para>
+
+ <para>The pstore file system supports a variety of backends that map onto persistent
+ storage, such as the ACPI ERST and UEFI variables. The pstore backends
+ typically offer a relatively small amount of persistent storage, e.g. 64KiB,
+ which can quickly fill up and thus prevent subsequent kernel crashes from
+ recording errors. Thus there is a need to monitor and extract the pstore
+ contents so that future kernel problems can also record information in the
+ pstore.</para>
+
+ <para>The pstore service is independent of the kdump service. In cloud environments
+ specifically, host and guest filesystems are on remote filesystems (eg. iSCSI
+ or NFS), thus kdump relies [implicitly and/or explicitly] upon proper operation
+ of networking software *and* hardware *and* infrastructure. Thus it may not be
+ possible to capture a kernel coredump to a file since writes over the network
+ may not be possible.</para>
+
+ <para>The pstore backend, on the other hand, is completely local and provides a path
+ to store error records which will survive a reboot and aid in post-mortem
+ debugging.</para>
+
+ <para>The <command>systemd-pstore</command> executable does the actual work. Upon starting,
+ the <filename>pstore.conf</filename> is read to obtain options, then the /sys/fs/pstore
+ directory contents are processed according to the options. Pstore files are written to the
+ journal, and optionally saved into /var/lib/systemd/pstore.</para>

Subject: [PATCH] pstore: allow specifying src and dst dirs are arguments
This makes it much easier to debug the program as a normal user, since we
don't need to set up fake input under /sys/fs/pstore/.
Also, let's make the debug output a bit nicer.

Let's use a more standard pattern: allocate memory using greedy_realloc, and
instead of freeing it when we wrote out a chunk, let's just move the cursor
back to the beginning and reuse the memory we allocated previously.
If we fail to allocate the memory for dmesg contents, don't write the dmesg
entry, but let's still process the files to move them out of pstore.

Subject: [PATCH] pstore: fixes for dmesg.txt reconstruction
This patch fixes problems with the re-assembly of the dmesg
from the records stored in pstore.
The current code simply ignores the last 6 characters of the
file name to form a base record id, which then groups any
pstore files with this base id into the reconstructed dmesg.txt.
This approach fails when the following oops generated the
following in pstore:

The above is a interleaved mess of three dmesg dumps.
This patch fixes the above problems, and simplifies the dmesg
reconstruction process. The code now distinguishes between
records on EFI vs ERST, which have differently formatted
record identifiers. Using knowledge of the format of the
record ids allows vastly improved reconstruction process.
With this change in place, the above pstore records now
result in the following:

Effectively this doesn't mean much, either way our unit is part of the

Subject: [PATCH] units: drop dependency on systemd-remount-fs.service from
systemd-pstore.service
This dependency is now generated automatically given we use
StateDirectory=. Moreover the combination of Wants= and After= was too
strong anway, as whether remount-fs is pulled in or not should not be up
to systemd-pstore.service, and in fact is part of the initial
transaction anyway.
[dtardon: This only removes Wants=, not After=, because I haven't
backported the auto-generation code the description talks about. The
code is simple, but it's just an optimisation allowing for slightly
shorter unit files, hence I don't think we really need it.]

Subject: [PATCH] pstore: Run after modules are loaded
The systemd-pstore service takes pstore files on boot and transfers them
to disk. It only does it once on boot and only if it finds any. The typical
location of the pstore on modern systems is the UEFI variable store.
Most distributions ship with CONFIG_EFI_VARS_PSTORE=m. That means, the
UEFI variable store is only available on boot after the respective module
is loaded.
In most situations, the pstore service gets loaded before the UEFI pstore,
so we don't get to transfer logs. Instead, they accumulate, filling up the
pstore over time, potentially breaking the UEFI variable store.
Let's add a service dependency on any kernel module that can provide a
pstore to ensure we only scan for pstate after we can actually see pstate.
I have seen live occurences of systems breaking because we did not erase
the pstates and ran out of UEFI nvram space.
Fixes https://github.com/systemd/systemd/issues/18540

Subject: [PATCH] pstore: do not try to load all known pstore modules
Commit 70e74a5997 ("pstore: Run after modules are loaded") added After=
and Wants= entries for all known kernel modules providing a pstore.
While adding these dependencies on systems where one of the modules is
not present, or not configured, should not have a real affect on the
system, it can produce annoying error messages in the kernel log. E.g.
"mtd device must be supplied (device name is empty)" when the mtdpstore
module is not configured correctly.
Since dependencies cannot be removed with drop-ins, if a distro wants to
remove some of these modules from systemd-pstore.service, they need to
patch units/systemd-pstore.service.in. On the other hand, if they want
to append to the dependencies this can be done by shipping a drop-in.
Since the original intent of the previous commit was to fix [1], which
only requires the efi_pstore module, remove all other kernel module
dependencies from systemd-pstore.service, and let distros ship drop-ins
to add dependencies if needed.

Subject: [PATCH] journald: Increase stdout buffer size sooner, when almost
full
If the previous received buffer length is almost equal to the allocated
buffer size, before this change the next read can only receive a couple
of bytes (in the worst case only 1 byte), which is not efficient.
