Hi * I copy paste the irc conversation with some great people, who helped me enlighting the problem (actually related to webview, for the notices tab, who behaves more or less like a browser)
<LocutusOfBorg> if browser-plugin-libreoffice is installed, boinc spawns soffice.bin/oosplash processes, but strace seems to give me some wx/glib pointers, rather than a bug in boinc <_rene_> LocutusOfBorg: no idea. I think there was a bug once saying something like "LO starts when iceweasel is started", but that wasn't really a big issue and afaicr not reproducible... <_rene_> LocutusOfBorg: but as you said, the plugin is g one.. but why does boinc handle mozilla plugins? should I know or d I better not want to? :) <LocutusOfBorg> I guess this is some wx/gtk initialization code <smcv> gtk, in general, doesn't load mozilla plugins <smcv> because why would it? <smcv> I don't know anything about wx, but I would hope that it doesn't either <smcv> but the strace logs you linked mention some sort of web view (presumably a more or less fully featured web browser wrapped in a Gtk widget) <smcv> and *that* is something that might reasonably load mozilla plugins <smcv> I would hope that it has APIs to tell it not to <smcv> e.g. webkitgtk has http://webkitgtk.org/reference/webkitgtk/stable/WebKitWebSettings.html#WebKitWebSettings--enable-plugins <smcv> I don't know what boinc does or why, but if its job does not include playing Flash and other misc embeddable plugins, it should configure its web view to not load those <LocutusOfBorg> smcv, yes, it uses webview <LocutusOfBorg> and it fetches the notices from the web in a tab <LocutusOfBorg> and this might be flash videos indeed <smcv> then it's essentially acting like a general-purpose web browser <LocutusOfBorg> actually I thought this was done when the user was clicking on "notices", but I might be wrong <LocutusOfBorg> it might be loaded at the startup and refreshed from time to time <LocutusOfBorg> yes indeed <smcv> I would hope that the part that displays notices has little or nothing to do with the part that runs as root <LocutusOfBorg> smcv, so when people starts a browser soffice is spawned? <LocutusOfBorg> I guess not <LocutusOfBorg> smcv, yes, they are decoupled <smcv> *shrug* _rene_ mentioned an unreproducible bug that had that effect <LocutusOfBorg> you don't even need the manager to run the client <LocutusOfBorg> _rene_, didn't mention the bug number :) <LocutusOfBorg> that webview is detestable <_rene_> I don't find that anymore <_rene_> even did look in archived for moilla-openoffice.org ;) <LocutusOfBorg> _rene_, moreover the package is gone, so I guess this is "fixed" some what <smcv> if the webview is meant to be as capable as a general-purpose web browser, then yes, if somebody puts a .so file in ~/.mozilla/plugins, it will be executed by the process hosting the webview <smcv> that's what general purpose web browsers do <LocutusOfBorg> smcv, so I guess that process soffice is for handling the plugin? <smcv> either they support plugins or they don't, you can't have it both ways <LocutusOfBorg> yes, but why java and flash don't spawn new processes when the plugins are loaded? <LocutusOfBorg> maybe they spawn and kill when they are needed <smcv> because the code in their plugins is different? <smcv> plugins are arbitrary native code <LocutusOfBorg> smcv, exactly, so I wonder if libreoffice might behave differently <smcv> if they want to spawn processes, they can spawn processes <smcv> if they want to rm -fr /, they can do that <LocutusOfBorg> I know that, I wonder if libreoffice is forced to do it, for some obscure reason to me <smcv> speculating about implementation specifics of a plugin that has been removed from debian is unlikely to lead to enlightenment <smcv> reading the relevant source code would probably be more informative <smcv> or uninstalling the no-longer-supported plugin and walking away <_rene_> nah, I'd actually believe direct initialization of this can be a LO plugin bug <_rene_> that one was unmaintained since ever, basically <_rene_> (and gone upstream now that's why it's not in sid anymore) <smcv> you seemed to be implying that this was a security vuln in ... I don't even know what. something that Debian supports. <smcv> but everything except the plugin itself seems to be working as intended <_rene_> only fixes were buildfixes, system-wide plugin even was a problem, etc <_rene_> Sun7Oracle only cared about the "click in the options to enable it (which does a ln -s in $HOMEs stuff) scenario cheers, Gianfranco Il Mercoledì 22 Luglio 2015 12:45, Gianfranco Costamagna <costamagnagianfra...@yahoo.it> ha scritto: Hi Alessandro and Rene, I see that libreoffice browser plugin giving troubles, and the problem seems to be not in boinc but in some wx code or libreoffice plugin code. I'm attaching a strace with and without that code. I'm also not so worried because that package seems to have disappeared in unstable, so I guess for Stretch this bug won't be spot anymore. However knowing what caused this might be useful. cheers, Gianfranco Il Martedì 21 Luglio 2015 21:44, Alessandro Barbieri <ale.bar...@alice.it> ha scritto: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Il 17/07/2015 15:34, Gianfranco Costamagna ha scritto: Successeful reproduced on a virtual machine you have to install browser-plugin-libreoffice File opened by one of the processes: Snapshot of files open in process 595 - /usr/lib/libreoffice/program/nsplugin 9 10 - -env:INIFILENAME=vnd.sun.star.pathname:/usr/lib/libreoffice/program/redi re FD TYPE DEVICE SIZE NODE NAME 0 CHR 0xb 5 /dev/pts/2 1 REG 0x807 0 534157 /home/ale/.BOINC/stdoutgui.t xt 2 REG 0x807 7490 534156 /home/ale/.BOINC/stderrgui.t xt 3 REG 0x806 57362 798881 /usr/lib/ure/share/misc/types.rdb 4 REG 0x806 8192 1315177 /usr/lib/libreoffice/share/extensions/writer2latex/writer2latex.rdb 5 REG 0x807 4 524392 /home/ale/BOINC Manager-ale 6 REG 0x806 346042 1320628 /usr/lib/libreoffice/program/types/oovbaapi.rdb 7 REG 0x806 665493 1320627 /usr/lib/libreoffice/program/types/offapi.rdb 9 FIFO 0x8 79200 pipe cwd DIR 0x807 12288 524289 /home/ale mem REG 0x806 8192 1315177 /usr/lib/libreoffice/share/extensions/writer2latex/writer2latex.rdb mem REG 0x806 14664 1185959 /lib/x86_64-linux-gnu/libdl-2.19.so mem REG 0x806 31256 664412 /usr/lib/ure/lib/libuno_salhelpergcc3.so.3 mem REG 0x806 31368 655653 /usr/lib/ure/lib/libuuresolverlo.so mem REG 0x806 31632 1188157 /lib/x86_64-linux-gnu/libnss_compat-2.19.so mem REG 0x806 31784 1188142 /lib/x86_64-linux-gnu/librt-2.19.so mem REG 0x806 43432 665244 /usr/lib/ure/lib/libxmlreaderlo.so mem REG 0x806 43592 1187078 /lib/x86_64-linux-gnu/libnss_nis-2.19.so mem REG 0x806 47712 1187077 /lib/x86_64-linux-gnu/libnss_files-2.19.so mem REG 0x806 57362 798881 /usr/lib/ure/share/misc/types.rdb mem REG 0x806 64432 669526 /usr/lib/ure/lib/libgcc3_uno.so mem REG 0x806 89104 1188484 /lib/x86_64-linux-gnu/libnsl-2.19.so mem REG 0x806 90096 1181345 /lib/x86_64-linux-gnu/libgcc_s.so.1 mem REG 0x806 109144 1180020 /lib/x86_64-linux-gnu/libz.so.1.2.8 mem REG 0x806 113496 928845 /usr/lib/libreoffice/program/libi18nlangtag.so mem REG 0x806 133576 665855 /usr/lib/ure/lib/libstorelo. so mem REG 0x806 134160 661012 /usr/lib/ure/lib/libreglo.so mem REG 0x806 137440 1188140 /lib/x86_64-linux-gnu/libpthread-2.19.so mem REG 0x806 140928 1182946 /lib/x86_64-linux-gnu/ld-2.19.so mem REG 0x806 141752 1179790 /lib/x86_64-linux-gnu/liblzma.so.5.0.0 mem REG 0x806 143520 664158 /usr/lib/liblangtag.so.1.2.0 mem REG 0x806 273416 664407 /usr/lib/ure/lib/libuno_cppu.so.3 mem REG 0x806 283744 669525 /usr/lib/ure/lib/libiolo.so mem REG 0x806 336304 662030 /usr/lib/ure/lib/libuno_sal.so.3 mem REG 0x806 346042 1320628 /usr/lib/libreoffice/program/types/oovbaapi.rdb mem REG 0x806 367568 669522 /usr/lib/ure/lib/libunoidllo.so mem REG 0x806 448440 1180019 /lib/x86_64-linux-gnu/libpcre.so.3.13.1 mem REG 0x806 614080 929194 /usr/lib/libreoffice/program/libucbhelper.so mem REG 0x806 665493 1320627 /usr/lib/libreoffice/program/types/offapi.rdb mem REG 0x806 1008120 656784 /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.20 mem REG 0x806 1042416 660857 /usr/lib/ure/lib/libuno_cppuhelpergcc3.so.3 mem REG 0x806 1051056 1188172 /lib/x86_64-linux-gnu/libm-2.19.so mem REG 0x806 1107040 1180615 /lib/x86_64-linux-gnu/libglib-2.0.so.0.4200.1 mem REG 0x806 1465816 656701 /usr/lib/x86_64-linux-gnu/libxml2.so.2.9.1 mem REG 0x806 1546256 696461 /usr/lib/x86_64-linux-gnu/libicuuc.so.52.1 mem REG 0x806 1613328 661399 /usr/lib/locale/locale-archi ve mem REG 0x806 1648696 922419 /usr/lib/libreoffice/program/libcomphelper.so mem REG 0x806 1729984 1188256 /lib/x86_64-linux-gnu/libc-2.19.so mem REG 0x806 23512848 696450 /usr/lib/x86_64-linux-gnu/libicudata.so.52.1 rtd DIR 0x806 4096 2 / txt REG 0x806 89256 918817 /usr/lib/libreoffice/program/nsplugin - -- <sip:alebar...@ekiga.net> -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJVrqEWAAoJEA/Z4QLlYWVuZjMIAIBXkDb8vXkEyaNQzju8Ks5F bJ3Pa6n4DdfW49BXXkSz7wWRyqTJHUTTvO4WCfiw36wnsE+vU4MSIZvyi6CJX5a7 owlVBK6xSm5ZIec9rbcG6WND1TiuAlBwpG1lHDT2cpQivYPM+UpSpP1hETGESyGx 9BOlvYZrRYn0/bjZFhM7sWjrFHcVuI4p+k+yLUsday5HHkjH3vpuO5UhK6bzEUue 4MsJGRhe1qxWUCUB1kLtpHj1OzpZ/dCmy2mjJSpBSI+MYZvMYGhoQc2EtpHNYtTv 7IClY4GtcRNwKPf1RONvpxTe7gg4XokmIN7vBfU6/my1ITE0BrBF5oGl92/UT3o= =OFpp -----END PGP SIGNATURE----- -- pkg-boinc-devel mailing list pkg-boinc-de...@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-boinc-devel -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
