I checked the kdbus-dev branch linked to by the kdbus Google Code page: https://review.tizen.org/git/?p=platform/upstream/dbus.git;a=shortlog;h=refs /heads/kdbus-dev But it hasn't been updated in over a year, and in that time kdbus has changed almost completely (i.e. now is kdbusfs...). As you stated kdbus has changed quite fast. That's the main reason why kdbus support development in libdbus was halted. Now, when kdbus is stabilizing we plan to restart the efforts with libdbus. Kdbus in glib is more mature, if you'd like to see it, you'll find it in official repo: https://git.gnome.org/browse/glib/log/?h=wip/kdbus-junk We will discuss it with dbus upstream. cheers, -- Maciej Wereski Samsung RD Institute Poland Samsung Electronics m.were...@partner.samsung.com ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel

Please use strv_consume() or strv_push() here, to make the additional

unquote_first_workd() fails due to parse errors.

Hmm, ths would mean we resolve the globbing twice. Once for
item_set_perms() and once for item_set_xattr(). I think it would be
better to do this in one call.
I've removed this completely. item_set_perms already calls label_fix,
which calls SMACK function.

[systemd-devel] [RFC] Mounting $XGD_RUNTIME_DIR with units instead of logind code.
Hello, Lately I've been working on updating systemd (currently 208) in Tizen. One of problems we've stumbled upon was with user@.service failing. Problem was on SMACK-enabled system, caused by 1c231f5 (logind: make $XDG_RUNTIME_DIR a per-user tmpfs). When $XDG_RUNTIME_DIR is mounted it inherits logind label, which in turn forbid users to access theirs directories. One solution would be to add if (use_smack()) mount(...smackfsroot=*...) in logind-user.c, but it would also require to add CAP_MAC_ADMIN to systemd-logind.service. Another solution would be to remove mounting logic from logind-user.c completely and add run-user@.mount. user@.service would gain following lines: Requires=run-user@%I.mount After=run-user@%I.mount Unfortunately, currently it's not possible. First problem is that unit isn't named after path, so that requirement needs to be removed first. Second - we don't have gid, but it doesn't seem to be an issue, as mode is set to 0700. Then, in Tizen we could just add smackfsroot to options. Alternatively SmackLabel= option could be added for mount units, which would automatically append smackfsroot to options, when SMACK is enabled. How should we solve this issue? regards, -- Maciej Wereski Samsung RD Institute Poland Samsung Electronics m.were...@partner.samsung.com ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel

Sounds like a job for the STRV_FOREACH() macro. Since you don't
actually
need the strv as strv here it sounds like you actually really want to
use FOREACH_WORD_QUOTED() for this, which will also do the unquoting
for
you.
Well, FOREACH_WORD_QUOTED() won't work properly, because quotation marks
aren't first chars in strings (e.g. user.name=John Smith). Maybe
better
idea would be to introduce mandatory separator (e.g. semicolon) instead
of
quotation marks.
Yeah, FOREACH_WORD_QUOTED() is quite badly designed. We should fix it to
do somewhat sane quoting and escaping. I'll look into it.
There is one problem with using it in this patch. In my case quotation
mark isn't first char of the string, so using pointer and length won't get
rid of it. String needs to be modified.

[systemd-devel] [PATCHv5] tmpfiles, man: Add xattr support to tmpfiles
This patch makes it possible to set extended attributes on files created by tmpfiles. This can be especially used to set SMACK security labels on volatile files and directories. It is done by adding new line of type t. Such line should contain attributes in Argument field, using following format: name=value All other fields are ignored. If value contains spaces, then it must be surrounded by quotation marks. User can also put quotation mark in value by escaping it with backslash. Example: D /var/run/cups - - - - t /var/run/cups - - - - security.SMACK64=printing --- I'm sorry for late reply, but there were some unexpected events which excluded me from life for a while. v5: * fixes for HAVE_XATTR undefined * use cunescape() instead of strreplace() * cache result of strv_length() * fix typo in manpage v4: * grammar fix in man * style fix v3: * may be used instead of should be used in manpage * use strv_isempty() instead of != NULL * rework item_set_xattrs() with split_pair() * remove copy_item_contents() * use hashmap_replace() instead of removed copy_item_contents() * use strv_extend() instead of strv_append() * cleanup --- man/tmpfiles.d.xml | 26 +- src/tmpfiles/tmpfiles.c | 216 +--- 2 files changed, 225 insertions(+), 17 deletions(-) diff --git a/man/tmpfiles.d.xml b/man/tmpfiles.d.xml index 1c079f6..676eded 100644 --- a/man/tmpfiles.d.xml +++ b/man/tmpfiles.d.xml @@ -248,6 +248,21 @@ L/tmp/foobar ---- /dev/null/programlisting place of normal path names./para/listitem /varlistentry + +varlistentry +termvarnamet/varname/term +listitemparaSet extended +attributes on item.

[systemd-devel] [PATCHv4] tmpfiles, man: Add xattr support to tmpfiles
This patch makes it possible to set extended attributes on files created
by tmpfiles. This can be especially used to set SMACK security labels on
volatile files and directories.
It is done by adding new line of type t. Such line should contain
attributes in Argument field, using following format:
name=value
All other fields are ignored.
If value contains spaces, then it must be surrounded by quotation marks.
User can also put quotation mark in value by escaping it with backslash.
Example:
D /var/run/cups - - - -
t /var/run/cups - - - - security.SMACK64=printing
---
v4:
* grammar fix in man
* style fix
v3:
* may be used instead of should be used in manpage
* use strv_isempty() instead of != NULL
* rework item_set_xattrs() with split_pair()
* remove copy_item_contents()
* use hashmap_replace() instead of removed copy_item_contents()
* use strv_extend() instead of strv_append()
* cleanup

I'd really prefer if we didn't corrupt the string here. Maybe use
strv_split_quoted() here? That handles all the values for you anyway...
You mean strv_split() (I'm splitting by =)? This has one issue: it
splits by all separator occurrences and I need to split after first one.
If corrupting string is the issue, I can make a copy of it. If you prefer
strv_split(), then I can just join if strv_length 2.

+i-xattrs = strv_append(i-xattrs, xattr);

For this stuf I'd really prefer using one of our already existing
quoting APIs, like strv_spit_quoted() or FOREACH_WORD_QUOTED or so.
Well, I've tried it in the beginning, but in doesn't work properly in this
case. split_quoted() expects quote on the beginning of a string (ignoring
whitespace occurrences). If there's no such case string will be split using
whitespace. Example of extended attribute with quotes:
user.test=This will \ fail
So how would you like this case to be solved?
regards,
Maciej

[systemd-devel] [PATCH v2] tmpfiles, man: Add xattr support to tmpfiles
This patch makes it possible to set extended attributes on files created by tmpfiles. This can be especially used to set SMACK security labels on volatile files and directories. It is done by adding new line of type t. Such line should contain attributes in Argument field, using following format: name=value All other fields are ignored. If value contains spaces, then it must be surrounded by quotation marks. User can also put quotation mark in value by escaping it with backslash. Example: D /var/run/cups - - - - t /var/run/cups - - - - security.SMACK64=printing --- I've used t because IMHO a will be better for acl. To sum up: when t is met and it's not in hashmap, then it will be added. Then if other line for the same file appears, then it replaces SET_XATTR item in hashmap and has extended attributes added. If item earler existed in hashmap, then extended attributes are merged to existing entry. This means that there can be more than one t lines for one file. There is also posibility to have standalone t line. I hope that this is desired behaviour. regards, Maciej --- man/tmpfiles.d.xml | 26 - src/tmpfiles/tmpfiles.c | 274 ++-- 2 files changed, 285 insertions(+), 15 deletions(-) diff --git a/man/tmpfiles.d.xml b/man/tmpfiles.d.xml index 519f9bc..92157b5 100644 --- a/man/tmpfiles.d.xml +++ b/man/tmpfiles.d.xml @@ -229,6 +229,21 @@ L/tmp/foobar ---- /dev/null/programlisting place of normal path names./para/listitem /varlistentry + +varlistentry +termvarnamet/varname/term +listitemparaSet extended +attributes on item.

Re: [systemd-devel] [PATCH] tmpfiles, man: Add xattr support to tmpfiles
Hello, On 17.06.2013 at 18:18 Lennart Poettering lenn...@poettering.net wrote: I think adding this certainly makes sense, but I am not sure I like the syntax. Maybe it would be simpler to add an extra char for this (a or so?). That way creating a dir and applying an xattr would require two lines instead of one, but the stuff isn't atomic anyway. Admittedly adding a new a isn't particularly nice either, but I have no better idea than that... I've looked into your way and found some problems. In parse_line(), after creating, item is added to hashmap. Key is path, which already exists in map. So adding a would require changing key (path + type?). Problem on user side is that order matters - if user would add a entry first, than setting attribute would fail, because file wouldn't exist yet. Should I continue adding a, look into Karols proposition or my original patch is acceptable? Anybody having other ideas? I've also found something which looks like a typo in lines 782 - 787: case RELABEL_PATH: r = glob_item(i, item_set_perms); if (r 0) return 0; break; Shouldn't it be return r? If it's not, then should I add comment, that it's on purpose? regards, Maciej -- Maciej Wereski Samsung RD Institute Poland Samsung Electronics m.were...@partner.samsung.com ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
[systemd-devel] [PATCH] tmpfiles, man: Add xattr support to tmpfiles
This patch makes it possible to set extended attributes on files created
by tmpfiles. This can be especially used to set SMACK security labels on
volatile files and directories.
To keep backwards compatibility Argument field is used. If word starts
with xattr=, then it is cut out from Argument and parsed. There may be
many xattrs. Full format is:
xattr=name=value
If value contains spaces, then it must be surrounded by quotation marks.
User can also put quotation mark in value by escaping it with backslash.
Example:
d /var/run/cups - - - - xattr=security.SMACK64=printing
