[Bug 581527] Re: udev segfaults in udev_monitor_enable_receiving when netlink doesn't work
This bug was fixed in the package udev - 161+git20100827-1
---
udev (161+git20100827-1) maverick; urgency=low
* Merge fixes from trunk:
- keymap: Fix Acer TravelMate 4720 (LP: #569815)
- gudev: fix crash if netlink is not available (LP: #581527)
- udev(7) manpage: Fix description of $attr (LP: #348513)
* debian/changelog: Fix bug reference in previous upload.
* debian/udev.{pre,post}inst: Remove pre-lucid upgrade code.
* debian/udev.postinst: Drop obsolete /lib/udev/devices/sndstat symlink, OSS
has gone from our kernels ages ago. (LP: #605443)
* debian/udev.postinst, create_devices(): Drop devices which are handled by
static_dev_create_links().
* debian/udev.postinst, create_devices(): Drop devices which are handled by
devtmpfs.
* debian/rules: Work around gtk-doc not being able to work in a separate
build tree; debian/rules prep already fixes $srcdir→$builddir, so copy
the relevant source files into the build tree so that gtk-doc has
something to scan for. (LP: #519670)
* Add debian/local/hotplug.functions: Provides some helper functions which
udev callouts can use. This is being used by usb-modeswitch, alsa, and
other Debian packages. Copied from current udev sid package. (LP: #625110)

Stephane, if this is important to you, please feel free to backport it to lucid and reopen the lucid task.

The current code in udev is quite inconsistent, though -- about half of the udev_monitor_*() functions return NULL if the passed monitor is NULL, the other half will crash. -- udev segfaults in udev_monitor_enable_receiving when netlink doesn't work https://bugs.launchpad.net/bugs/581527 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Looking at the stacktrace and rhythmbox code, it actually crashes in g_udev_client_new().

Sorry, I don't agree with this patch.

Note that the bug here is clearly in rhythmbox, libudev correctly returns NULL for the monitor because there is no netlink socket - and rhythmbox failed to check for that, and blindly passed that NULL around assuming it was a valid object ** Changed in: udev (Ubuntu Lucid) Status: New = Won't Fix ** Changed in: udev (Ubuntu Maverick) Status: New = Triaged ** Changed in: udev (Ubuntu Maverick) Importance: Undecided = Low ** Also affects: rhythmbox (Ubuntu) Importance: Undecided Status: New -- udev segfaults in udev_monitor_enable_receiving when netlink doesn't work https://bugs.launchpad.net/bugs/581527 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 581527] Re: udev segfaults in udev_monitor_enable_receiving when netlink doesn't work
Won't Fix the lucid udev, the correct patch merely turns a segfault into an assertion error and will still terminate the process. Will send adding an assert in there upstream for maverick though Opened the bug on rhythmbox for not checking the return value is not NULL before blindly passing it around -- udev segfaults in udev_monitor_enable_receiving when netlink doesn't work https://bugs.launchpad.net/bugs/581527 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 581527] Re: udev segfaults in udev_monitor_enable_receiving when netlink doesn't work
I know that using lucid in a container on top of an older kernel (in this case Hardy's) is not recommended and is known to fail. Most users doing that know that, though I believe that if something can be fixed in udev to correctly fail rather than segfault, it's still worth fixing.

Ok, so that patch does the trick.

Here's a debdiff for Lucid. It seems like Debian isn't using any kind of patching system, so that's a patch directly applied to upstream code + it's changelog entry targeted at lucid-proposed. As for maverick, I believe that this bug should be fixed upstream and will then be pulled from a new udev in Debian without needing any ubuntu-specific release (as udev is currently synced from Debian). ** Patch added: debdiff for lucid-proposed http://launchpadlibrarian.net/48582648/libudev-monitor.c.diff ** Changed in: udev (Ubuntu) Milestone: None = lucid-updates ** Changed in: udev (Ubuntu) Milestone: lucid-updates = None ** Also affects: udev (Ubuntu Maverick) Importance: Undecided Status: New ** Also affects: udev (Ubuntu Lucid) Importance: Undecided Status: New ** Changed in: udev (Ubuntu Lucid) Milestone: None = lucid-updates -- udev segfaults in udev_monitor_enable_receiving when netlink doesn't work https://bugs.launchpad.net/bugs/581527 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
