Let's introduce a common function that makes relative paths absolute and
warns about any errors while doing so.
|
|
get_current_dir_name() can return a variety of errors, not just ENOMEM,
hence don't blindly turn its errors to ENOMEM, but return correct errors
in path_make_absolute_cwd().
This trickles down into a couple of other functions, some of which
receive unrelated minor fixes too with this commit.

|
No functional change. Just a simplification. A || (!A && B) is
the same as A || B
Introduced in 78a92a5a2306709e4587e332728a76901323ade9

This allows us to set up the quota group hierarchy in a reasonable way
on btrfs file systems.
|
|
This also allows us to drop build.h from a ton of files, hence do so.
Since we touched the #includes of those files, let's order them properly
according to CODING_STYLE.
|
|
This adds an EXTRACT_QUOTES option to allow the previous behaviour, of
not interpreting any character inside ' or " quotes as separators.
|
|
It now takes a separators argument, which defaults to WHITESPACE if NULL
is passed.

This downgrades errors from setting file attributes via tmpfiles to
warnings and makes them non-fatal.
Also, as a special case, if a file system does not support file
attributes at all, then the message is downgraded to debug, so that it
is not seen at all.
With this change reiserfs should not see any messages at all anymore
(since it apparently does not implement file attributes at all), but XFS
will still get a warning but no failure. The warning is something the
XFS kernel folks should fix though, by adjusting their file attributes
behaviour to be identical to ext234's.
Fixes #560.

So far a number of utilities implemented their own calls for this, unify
them in prefix_root() and prefix_roota(). The former uses heap memory,
the latter allocates from the stack via alloca().
Port over most users of a --root= logic.

|
On read-only filesystems trying to create the target will not fail with
EEXIST but with EROFS. Handle EROFS by checking if the target already
exists, and if empty when truncating.
This avoids reporting errors if tmpfiles doesn't actually needs to do
anything.
[zj: revert condition to whitelist rather then blacklisting, and add goto
to avoid stat'ting twice.]

We should try to execute them in the same order they appear in the
configuration files, as it is documented. Hence move to an ordered
hashmap.
(Note though, that this still doesn't execute them completely in order:
we will still apply non-glob lines before glob-lines, and reorder lines
prefixing each other and that apply to the same paths).

Clang is not happy about using the cleanup attribute in switches
|
|
|
|
Always create files first, and then adjust their ACLs, xattrs, file
attributes, never the opposite. Previously the order was not
deterministic, thus possibly first adjusting ACLs/xattrs/file
attributes before actually creating the items.

Add a comment why returning a positive error is OK and intended in this
case.
(It's still a nasty hack to do this though!)

- Stick to one type for the flags field: unsigned. This appears to be
what the kernel uses, and there's no point in using something else.
- compress the flags array by avoiding sparse entries
- extend some error messages to not use abbreviated words
- avoid TTOCTTOU issues by invoking fstat() after open() when applying
file flags
- add explanation why we need to check the file type with fstat().
- don't needlessly abbreviate "attribute" as "attrib", in particually as
"chattr" abbreviates it as "attr" rather than "attrib".

Change cunescape() to return a normal error code, so that we can
distuingish OOM errors from parse errors.
This also adds a flags parameter to control whether "relaxed" or normal
parsing shall be done. If set no parse failures are generated, and the
only reason why cunescape() can fail is OOM.
|
|
- Move to its own file rm-rf.c
- Change parameters into a single flags parameter
- Remove "honour sticky" logic, it's unused these days
|
|
When parsing words from input files, optionally automatically unescape
the passed strings, controllable via a new flags parameter.
Make use of this in tmpfiles, and port everything else over, too.
This improves parsing quite a bit, since we no longer have to process the
same string multiple times with different calls, where an earlier call
might corrupt the input for a later call.

Otherwise this will go wrong for 'v'.

Allow systemd-tmpfiles to set the file/directory attributes, like
chattr(1) does. Two more commands are added: 'H' and 'h' to set the
attributes, recursively and not.

Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.

Commit 3f93da987 accidentally dropped the "return 0" after detection of a
duplicate line. Put it back, to get back the documented and intended "first
match wins" behaviour.

A warning is printed if ACLs cannot be retrieved for any reason other
than -ENOSYS. For -ENOSYS, debug log is printed.

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

parse_acl() returns the error instead of setting errno.
