http://bugzilla.opensuse.org/show_bug.cgi?id=1106103 Bug ID: 1106103 Summary: owncloud-client v2.4.2 segfaults Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: X11 Applications Assignee: bnc-team-screening(a)forge.provo.novell.com Reporter: aeszter(a)gwdg.de QA Contact: qa-bugs(a)suse.de Found By: --- Blocker: --- On my system, the owncloud client (executable is named owncloud) always segfaults immediately after launch. v2.4.1 used to work fine. This may be triggered by my desktop environment (i3), although I did not analyze beyond the following: The culprit appears to be fix-systray-menu-pos.patch: with upstream, platformMenu is checked against NULL before dereferencing it; but with the patch, the pointer is dereferenced unconditionally, the NULL check comes too late. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1124057] New: GNOME:Factory/gnome-documents: Gnome Books won't load comics by default

http://bugzilla.opensuse.org/show_bug.cgi?id=1124057 Bug ID: 1124057 Summary: GNOME:Factory/gnome-documents: Gnome Books won't load comics by default Classification: openSUSE Product: openSUSE.org Version: unspecified Hardware: x86-64 OS: openSUSE Factory Status: NEW Severity: Minor Priority: P5 - None Component: 3rd party software Assignee: os.gnome.maintainers(a)gmail.com Reporter: ibboard(a)gmail.com QA Contact: bnc-team-screening(a)forge.provo.novell.com Found By: --- Blocker: --- Gnome Books will list comics (e.g. CBZ files) but won't open them. It doesn't make it clear why and just says "Ooops,! Unable to load [file name]. File type Zip archive (application/zip) is not supported". The failure is because Gnome Books relies on evince for rendering, and evince-plugin-comicsdocument is required to load comics. I reported this upstream to get a more useful error message put in and they basically told me to go away and install the Flatpak, or get my distro to fix the dependencies (https://gitlab.gnome.org/GNOME/gnome-books/issues/15#note_427255) So, please can you add evince-plugin-comicsdocument as a dependency (or Recommends) to Gnome Books so that users don't get confused by it not opening comic books? -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1104824] New: Bug in xen-netfront.c, concerning replacement of MAX_SKB_FRAGS with XEN_NETIF_NR_SLOTS_MIN
by bugzilla_noreply＠novell.com 02 Feb '19

http://bugzilla.suse.com/show_bug.cgi?id=1104824 Bug ID: 1104824 Summary: Bug in xen-netfront.c, concerning replacement of MAX_SKB_FRAGS with XEN_NETIF_NR_SLOTS_MIN Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: Linux Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers(a)forge.provo.novell.com Reporter: Manfred.Haertel(a)rz-online.de QA Contact: qa-bugs(a)suse.de Found By: --- Blocker: --- After a recent kernel upgrade in a DomU, which run on a system with an older kernel in Dom0, the DomU crashed on heavy incoming network load. So I filed https://bugzilla.suse.com/show_bug.cgi?id=1102997 and later I invalidated my own bug report, because I could not reproduce the bug with a current Dom0 kernel. However, after some debugging and trying to understand how the driver works, I still think that the change where MAX_SKB_FRAGS was replaced by XEN_NETIF_NR_SLOTS_MIN is not completely correct. I hope my wording is correct (or at least understandable), trying to explain what I think is wrong. The variable max in xennet_get_responses() can now become larger by one than before. BEFORE the patch, the variable was 17 or 18, depending on rx->status <= RX_COPY_THRESHOLD, which means it depends on the size of the first fragment. If the first fragment was larger than the threshold, the variable became 17, and 18 otherwise. So, if a (ethernet GSO) frame with 18 fragments was received AND the first fragment was "large" (larger than the threshold), the condition slots > max in xennet_get_responses() was met, and the whole frame was discarded (and the infamous message "Too many slots" appeared). I don't think the Xen network code allows a frame with 19 fragments, so the condition slots > max could not be met at all when the first fragment was "small". So, in xennet_fill_frags() we could be sure, that if we have a frame with 18 fragments, then the first fragment would be "small". In THIS case, if the condition shinfo->nr_frags == MAX_SKB_FRAGS was met (meaning we have 18 fragments), we knew that the first fragment was small and so __pskb_pull_tail() was able to decrement nr_frags by one. So, BUG_ON(shinfo->nr_frags >= MAX_SKB_FRAGS) could never lead to a crash because nr_frags was now smaller than MAX_SKB_FRAGS. NOW the variable max in xennet_get_responses() can become 18 or 19, again depending on the size of the first fragment. Again, as (I think) a frame with 19 or even 20 fragments is not possible, the condition slots > max is NEVER met and the message "Too many slots" is actually impossible. However, in xennet_fill_frags() things are different. A frame with 18 fragments is now possible even if the first fragment is "large" (larger than RX_COPY_THRESHOLD). The problem is, that in this case __pskb_pull_tail() is NOT able to decrement shinfo->nr_frags by one. I THINK this is coded in the following lines in xennet_poll(): NETFRONT_SKB_CB(skb)->pull_to = rx->status; if (NETFRONT_SKB_CB(skb)->pull_to > RX_COPY_THRESHOLD) NETFRONT_SKB_CB(skb)->pull_to = RX_COPY_THRESHOLD; (I admit that I do not really understand what this actually does). So, with a "large" first fragment, shinfo->nr_frags is *still* MAX_SKB_FRAGS (18) after the pull, and so BUG_ON(shinfo->nr_frags >= MAX_SKB_FRAGS); causes a crash. It seems that the crash does NOT happen with a recent Dom0 kernel. I also tried to understand why. It seems as if the xen-netback driver in recent kernels does send only a maximum of *16* fragments (at least, I could not provoke it to send more). So, of course, the crash can never happen. On the other hand, I think, the code in xen-netfront is not correct in general. A Dom0 kernel which sends 18 fragments with a "large" first fragment is able to crash the DomU. For example, older linux kernels in Dom0, though I do not know when the change in netback to a fewer number of fragments happened. I also do not understand which is the universally correct solution. -- You are receiving this mail because: You are on the CC list for the bug.
