From 79df4db3fd122f5040bdf2225c3047375de3b0d2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] build-sys: Detect whether struct statx is defined in
sys/stat.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Starting with glibc 2.27.9000-36.fc29, include file sys/stat.h will have a
definition for struct statx, in which case include file linux/stat.h should be
avoided, in order to prevent a duplicate definition.
In file included from ../src/basic/missing.h:18,
from ../src/basic/util.h:28,
from ../src/basic/hashmap.h:10,
from ../src/shared/bus-util.h:12,
from ../src/libsystemd/sd-bus/bus-creds.c:11:
/usr/include/linux/stat.h:99:8: error: redefinition of ‘struct statx’
struct statx {
^~~~~

from ../src/basic/util.h:19,
from ../src/basic/hashmap.h:10,
from ../src/shared/bus-util.h:12,
from ../src/libsystemd/sd-bus/bus-creds.c:11:
/usr/include/bits/statx.h:36:8: note: originally defined here
struct statx
^~~~~
Extend our meson.build to look for struct statx when only sys/stat.h is
included and, in that case, do not include linux/stat.h anymore.
Tested that systemd builds correctly when using a glibc version that includes a
definition for struct statx.

Subject: [PATCH] bus: move BUS_DONT_DESTROY calls after asserts
It's not useful to bump the reference count before checking if the object is
NULL. Thanks to d40f5cc498 we can do this ;).
Related to https://bugzilla.redhat.com/show_bug.cgi?id=1576084,
https://bugzilla.redhat.com/show_bug.cgi?id=1575340,
https://bugzilla.redhat.com/show_bug.cgi?id=1575350. I'm not sure why those two
people hit this code path, while most people don't. At least we won't abort.
(cherry picked from commit 7ae8edcd03f74da123298330b76c3fc5425042ef)
Resolves: #1610397

Subject: [PATCH] bus-message: do not crash on message with a string of zero
length
We'd calculate the "real" length of the string as 'item_size - 1', which does
not work out well when item_size == 0.

Subject: [PATCH] Introduce free_and_strndup and use it in bus-message.c
v2: fix error in free_and_strndup()
When the orignal and copied message were the same, but shorter than specified
length l, memory read past the end of the buffer would be performed. A test
case is included: a string that had an embedded NUL ("q\0") is used to replace
"q".
v3: Fix one more bug in free_and_strndup and add tests.
v4: Some style fixed based on review, one more use of free_and_replace, and
make the tests more comprehensive.
(cherry picked from commit 7f546026abbdc56c453a577e52d57159458c3e9c)

Subject: [PATCH] resolved: create /etc/resolv.conf symlink at runtime
If the symlink doesn't exists, and we are being started, let's
create it to provie name resolution.
If it exists, do nothing. In particular, if it is a broken symlink,
we cannot really know if the administator configured it to point to
a location used by some service that hasn't started yet, so we
don't touch it in that case either.

Subject: [PATCH] proc-cmdline: introduce PROC_CMDLINE_RD_STRICT
Our current set of flags allows an option to be either
use just in initrd or both in initrd and normal system.
This new flag is intended to be used in the case where
you want apply some settings just in initrd or just
in normal system.

Subject: [PATCH] chown-recursive: let's rework the recursive logic to use
O_PATH
That way we can pin a specific inode and analyze it and manipulate it
without it being swapped out beneath our hands.
Fixes a vulnerability originally found by Jann Horn from Google.

Subject: [PATCH] Revert "sysctl.d: request ECN on both in and outgoing
connections"
Turning on ECN still causes slow or broken network on linux. Our tcp
is not yet ready for wide spread use of ECN.
This reverts commit 919472741dba6ad0a3f6c2b76d390a02d0e2fdc3.

Subject: [PATCH] detect-virt: do not try to read all of /proc/cpuinfo
Quoting https://github.com/systemd/systemd/issues/10074:
> detect_vm_uml() reads /proc/cpuinfo with read_full_file()
> read_full_file() has a file max limit size of READ_FULL_BYTES_MAX=(4U*1024U*1024U)
> Unfortunately, the size of my /proc/cpuinfo is bigger, approximately:
> echo $(( 4* $(cat /proc/cpuinfo | wc -c)))
> 9918072
> This causes read_full_file() to fail and the Condition test fallout.
Let's just read line by line until we find an intersting line. This also
helps if not running under UML, because we avoid reading as much data.

Subject: [PATCH] sd-bus: properly initialize containers
Fixes a SIGSEGV introduced by commit 38a5315a3a6fab745d8c86ff9e486faaf50b28d1.
The same problem doesn't exist upstream, as the container structure
there is initialized using a compound literal, which is zeroed out by
default.

Subject: [PATCH] cryptsetup-generator: introduce basic keydev support
Dracut has a support for unlocking encrypted drives with keyfile stored
on the external drive. This support is included in the generated initrd
only if systemd module is not included.
When systemd is used in initrd then attachment of encrypted drives is
handled by systemd-cryptsetup tools. Our generator has support for
keyfile, however, it didn't support keyfile on the external block
device (keydev).
This commit introduces basic keydev support. Keydev can be specified per
luks.uuid on the kernel command line. Keydev is automatically mounted
during boot and we look for keyfile in the keydev
mountpoint (i.e. keyfile path is prefixed with the keydev mount point
path). After crypt device is attached we automatically unmount
where keyfile resides.
Example:
rd.luks.key=70bc876b-f627-4038-9049-3080d79d2165=/key:LABEL=KEYDEV
(cherry-picked from commit 70f5f48eb891b12e969577b464de61e15a2593da)
Resolves: #1656869

+ <para>It is also possible to specify an external device which

+ systemd-cryptsetup will use password file stored on that

Subject: [PATCH] cryptsetup: don't use %m if there's no error to show
We are not the ones receiving an error here, but the ones generating it,
hence we shouldn't show it with %m, that's just confusing, as it
suggests we received an error from some other call.

Subject: [PATCH] sysctl.d: switch net.ipv4.conf.all.rp_filter from 1 to 2
This switches the RFC3704 Reverse Path filtering from Strict mode to Loose
mode. The Strict mode breaks some pretty common and reasonable use cases,
such as keeping connections via one default route alive after another one
appears (e.g. plugging an Ethernet cable when connected via Wi-Fi).
The strict filter also makes it impossible for NetworkManager to do
connectivity check on a newly arriving default route (it starts with a
higher metric and is bumped lower if there's connectivity).
Kernel's default is 0 (no filter), but a Loose filter is good enough. The
few use cases where a Strict mode could make sense can easily override
this.
The distributions that don't care about the client use cases and prefer a
strict filter could just ship a custom configuration in
/usr/lib/sysctl.d/ to override this.

Date: Mon, 16 Jul 2018 11:27:44 +0200
Subject: [PATCH] test: Drop SKIP_INITRD for QEMU-based tests
Not all distros support booting without an initrd. E.g. the Debian
kernel builds ext4 as a module and so relies on an initrd to
successfully start the QEMU-based images.

This should be much better than fgets(), as we can read substantially
longer lines and overly long lines result in proper errors.

Subject: [PATCH] coredump: remove duplicate MESSAGE= prefix from message
systemd-coredump[9982]: MESSAGE=Process 771 (systemd-journal) of user 0 dumped core.
systemd-coredump[9982]: Coredump diverted to /var/lib/systemd/coredump/core...
log_dispatch() calls log_dispatch_internal() which calls write_to_journal()
which appends MESSAGE= on its own.

Subject: [PATCH] journald: do not store the iovec entry for process
commandline on stack
This fixes a crash where we would read the commandline, whose length is under
control of the sending program, and then crash when trying to create a stack
allocation for it.
CVE-2018-16864
https://bugzilla.redhat.com/show_bug.cgi?id=1653855
The message actually doesn't get written to disk, because
journal_file_append_entry() returns -E2BIG.
(cherry-picked from commit 084eeb865ca63887098e0945fb4e93c852b91b0f)

2MB might be hard for some clients to use meaningfully, but OTOH, it is
important to log the full commandline sometimes. For example, when the program
is crashing, the exact argument list is useful.

Subject: [PATCH] procfs-util: expose functionality to query total memory
procfs_memory_get_current is renamed to procfs_memory_get_used, because
"current" can mean anything, including total memory, used memory, and free
memory, as long as the value is up to date.
No functional change.

Subject: [PATCH] journal: limit the number of entries in the cache based on
available memory
This is far from perfect, but should give mostly reasonable values. My
assumption is that if somebody has a few hundred MB of memory, they are
unlikely to have thousands of processes logging. A hundred would already be a
lot. So let's scale the cache size propritionally to the total memory size,
with clamping on both ends.
The formula gives 64 cache entries for each GB of RAM.

Subject: [PATCH] journald: periodically drop cache for all dead PIDs
In normal use, this allow us to drop dead entries from the cache and reduces
the cache size so that we don't evict entries unnecessarily. The time limit is
there mostly to serve as a guard against malicious logging from many different
PIDs.

Subject: [PATCH] journald: set a limit on the number of fields (1k)
We allocate a iovec entry for each field, so with many short entries,
our memory usage and processing time can be large, even with a relatively
small message size. Let's refuse overly long entries.
CVE-2018-16865
https://bugzilla.redhat.com/show_bug.cgi?id=1653861
What from I can see, the problem is not from an alloca, despite what the CVE
description says, but from the attack multiplication that comes from creating
many very small iovecs: (void* + size_t) for each three bytes of input message.

Subject: [PATCH] journald: when processing a native message, bail more quickly
on overbig messages
We'd first parse all or most of the message, and only then consider if it
is not too large. Also, when encountering a single field over the limit,
we'd still process the preceding part of the message. Let's be stricter,
and check size limits early, and let's refuse the whole message if it fails
any of the size limits.

We immediately read the whole contents into memory, making thigs much more
expensive. Sealed fds should be used instead since they are more efficient
on our side.

Subject: [PATCH] journal-remote: verify entry length from header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Calling mhd_respond(), which ulimately calls MHD_queue_response() is
ineffective at point, becuase MHD_queue_response() immediately returns
MHD_NO signifying an error, because the connection is in state
MHD_CONNECTION_CONTINUE_SENT.
As Christian Grothoff kindly explained:
> You are likely calling MHD_queue_repsonse() too late: once you are
> receiving upload_data, HTTP forces you to process it all. At this time,
> MHD has already sent "100 continue" and cannot take it back (hence you
> get MHD_NO!).
>
> In your request handler, the first time when you are called for a
> connection (and when hence *upload_data_size == 0 and upload_data ==
> NULL) you must check the content-length header and react (with
> MHD_queue_response) based on this (to prevent MHD from automatically
> generating 100 continue).
If we ever encounter this kind of error, print a warning and immediately
abort the connection. (The alternative would be to keep reading the data,
but ignore it, and return an error after we get to the end of data.
That is possible, but of course puts additional load on both the
sender and reciever, and doesn't seem important enough just to return
a good error message.)
Note that sending of the error does not work (the connection is always aborted
when MHD_queue_response is used with MHD_RESPMEM_MUST_FREE, as in this case)
with libµhttpd 0.59, but works with 0.61:

Subject: [PATCH] journal-remote: set a limit on the number of fields in a
message
Existing use of E2BIG is replaced with ENOBUFS (entry too long), and E2BIG is
reused for the new error condition (too many fields).
This matches the change done for systemd-journald, hence forming the second
part of the fix for CVE-2018-16865
(https://bugzilla.redhat.com/show_bug.cgi?id=1653861).
(cherry-picked from commit ef4d6abe7c7fab6cbff975b32e76b09feee56074)
Resolves: #1664977

Subject: [PATCH] journald: correctly attribute log messages also with
cgroupsv1
With cgroupsv1 a zombie process is migrated to root cgroup in all
hierarchies. This was changed for unified hierarchy and /proc/PID/cgroup
reports cgroup to which process belonged before it exited.
Be more suspicious about cgroup path reported by the kernel and use
unit_id provided by the log client if the kernel reports that process is
running in the root cgroup.
Users tend to care the most about 'log->unit_id' mapping so systemctl
status can correctly report last log lines. Also we wouldn't be able to
infer anything useful from "/" path anyway.
See: https://github.com/torvalds/linux/commit/2e91fa7f6d451e3ea9fec999065d2fd199691f9d

Subject: [PATCH] test: replace echo with socat
The original version of the test used netcat along with a standard
AF_UNIX socket, which caused issues across different netcat
implementations. The AF_UNIX socket was then replaced by a FIFO with a
simple echo, which, however, suffers from the same issue (some echo
implementations don't check if the write() was successful).
Let's revert back to the AF_UNIX socket, but replace netcat with socat,
which, hopefully, resolves the main issue.

Subject: [PATCH] rules: implement new memory hotplug policy
Our new policy is based on following motivations (assumptions),
* we want to allow the system to use hotplugged memory
* we want memory ballon inflation to work as expected in VMs (going for small
to big in terms of memory footprint)
* we want to allow memory hotplug and memory hot-unplug on high-end
enterprise server (we assume that node0 will have sufficient memory
resources and marking all memory as movable shouldn't be a problem)
Policy:
* nevert online memory on s390 (on both physical and z/VM)
* mark memory as "online_movable" on physical machines
* mark memory as "online" in VMs
If you have the feeling that all this is very wrong and we shouldn't
encode complex policies in udev rules you are absolutely right. However,
for now, we don't have any better place where to put it. In ideal world
we would have a user-space daemon that would be able to configure the
system wrt. to currently present HW and user-defined policy.

Subject: [PATCH] lgtm: add a custom query for catching the use of fgets
As everybody knows, nodoby really reads CODING_STYLE (especially

use of fgets.
(cherry picked from commit f86c1da28340f2a2afd34d72c9f416a2a94219a8)
