This makes path_is_mount_point() consistent with fd_is_mount_point() wrt.
flags.
|
|
Commits 27cc6f166 and f25afeb broke path_is_mount_point() for files (such as
/etc/machine-id → /run/machine-id bind mounts) as with the factorization of
fd_is_mount_point() we lost the parent directory. We cannot determine that from
an fd only as openat(fd, "..") only works for directory fds.
Change fd_is_mount_point() to behave like openat(): It now takes a file
descriptor of the containing directory, a file name in it, and flags (which can
be 0 or AT_SYMLINK_FOLLOW). Unlike name_to_handle_at() or openat(), fstatat()
only accepts the inverse flag AT_SYMLINK_NOFOLLOW and complains with EINVAL
about AT_SYMLINK_FOLLOW; so we need to transform the flags for that fallback.
Adjust rm_rf_children() accordingly (only other caller of fd_is_mount_point()
aside from path_is_mount_point()).
Add test cases for files, links, and file bind mounts (the latter will only
work when running as root). Split out a new test_path_is_mount_point() test
case function as it got significantly larger now.

If there is both a SysV init.d script and a systemd unit for a given name, we
want to do the same enable/disable operation for both, instead of just on the
systemd unit. This keeps the enablement status in sync so that switching init
systems behaves as expected.

Introduce /usr/lib/systemd/systemd-sysv-install [--root=] <action> <name>
abstraction, replacing the direct calling of chkconfig. This allows
distributions to call their specific tools like update-rc.d without patching
systemd.
Ship systemd-sysv-install.SKELETON as an example for packagers how to implement
this.
Drop the --enable-chkconfig configure option.
Document this in README and point to it in NEWS.

This was a regression that broke

A NULL pointer was inserted as the first element of the strv.
This had the effect of always passing the empty environment to processes
spawned by udev.

Make Coverity happy and tell it we're not interested in the return

When a scheduled is cancelled, make sure to remove /run/nologin.
This is a regression from the recent shutdownd removal and logind rework.

udevd: worker - fully clean up unnecessary fds
The inotify-fd _is_ used in the workers, so don't close it! Have a look at
udev-watch.c, which keeps track of the inotify-fd as a global variable
(ugh!).

Fixes CID CID 1299638 (use after free).

This was a typo, swapping prefix_root() in place of prefix_roota().
Fixes CID 1299640.

Simplify the code a bit, at the cost of potentially duplicating some
memory unneccessarily.
Fixes CID 1299641.

These have no effect.
Fixes CID 1299643.

A malformed manifest could in principle cause a NULL pointer dereference of. Check
for this and fail early.
Fixes CID 1299642.

Rather than checking the return of asprintf() we are checking if buf gets allocated,
make it clear that it is ok to ignore the return value.
Fixes CID 1299644.

Passing ipv6 options (even when they should be noops) caused IFF_UP to fail when
ipv6 was supported.

This patch simplify swapon usage in systemd. The command swapon(8)
since util-linux v2.26 supports "-o <list>". The idea is exactly the
same like for mount(8). The -o specifies options in fstab-compatible
way. For systemd it means that it does not have to care about things
like "discard" or another swapon specific options.
swapon -o <options-from-fstab>
For backward compatibility the code cares about "Priority:" swap unit
field (for a case when Priority: is set, but pri= in the Options: is
missing).

In generated systemd-fsck-root.service. This would break if rootprefix
is not /usr/lib/systemd.

Allowed interface name is relatively small. Lets not make
users go in to the source code to figure out what happened.

We would enforce that events could only be added to the queue from the
main process, but that brake in daemonized mode. Relax the restriction
to only allow one process to add events to the queue.

Initialize structs when declaring rather than using memzero().

These are only ever used in the parent process, so close them early in the worker.

The original code used fread(), which on some libc implementions
(ie glibc 2.17) would pre-read a full 4K (PAGE_SIZE) of the
PCI config space, when only 64 bytes were requested.
I have recently come across PCIe hardware which responds with
Completion Timeouts when accesses above 256 bytes are attempted.
This can cause server systems with GHES/AEPI support to cause
and immediate kernel panic due to the failed PCI transaction.
This change replaces the buffered fread() with an explict
unbuffered read() of 64 bytes, which corrects this issue by
only reading the guaranteed first 64 bytes of PCIe config space.

With the v221 release these APIs should be public, stable APIs, hence
let's install their headers by default now, and add their symbols to the
.sym file.

The parser used for MTU and Speed expects them to be size_t, not unsigned int.
This caused a corruption in the rest of the structure.

Do not print garbage on non-EFI installations.

Use strjoina to avoid error handling, and openat to simplify things.
Some fixes on the way:
- ferror does not set errno, so the return value was wrong in some cases
- errors are propagated in more cases
- EFI/systemd was created, but EFI/systemd-boot was deleted
- something is always printed on error
- when checking the version, comparison was done against "systemd-bo" for some reason
- return value was converted from negative to EXIT_SUCCESS/EXIT_FAILURE twice,
resulting in EXIT_SUCCESS all the time
