[Bug 401028] Re: telepathy-butterfly crashed with TypeError in b64decode()
Laurent: First off, thanks so much for the backtrace; it's exactly what I thought it would be. Should this not be filed as a new bug? The patch for the corrupt shac value blatantly ignores the exception (just logs it) because the value is not used anywhere else, and ignoring it follows the logic of the rest of the codebase. However, ignoring corrupted shad values in this way could be a bad idea. If the data hash is corrupt, that signals that the data (a profile icon for example) could also be corrupt. Now, there are two reasonable ways to fix this: A) Follow the logic set in place by the codebase as if the data hashes, while valid, don't match. I haven't look at the code yet but I believe that logic is to drop the invalid data message. After logging, this would be the proper way to handle corrupt data imo. B) Let FD.o take care of it. It should be up to them how they want to handle corrupt messages. Unfortunately there are still many unchecked exceptions throughout papyon aside from this one. -- telepathy-butterfly crashed with TypeError in b64decode() https://bugs.launchpad.net/bugs/401028 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 401028] Re: telepathy-butterfly crashed with TypeError in b64decode()
Can anyone with the error on lucid please file a separate bug and attach a backtrace? On launchpad, insist that it is not a duplicate bug. The original exception is caught and ignored, so this exception must be happening elsewhere, likely in the b64decode of the other data hash nearby (sha1d). -- telepathy-butterfly crashed with TypeError in b64decode() https://bugs.launchpad.net/bugs/401028 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 401028] Re: telepathy-butterfly crashed with TypeError in b64decode()
I've reproduced this locally by sending a malformed SHA1C value via an msn_object avatar. It's not as trivial to reproduce using the telepathy/papyon framework since SHA1C values are normally ignored in all cases, but still processed. Yes, you read that correctly. Going along with upstream's methodology that the checksum is redundant and all that is necessary is the data (for which the hash is properly compared and handled), I've written a patch to silently ignore malformed checksums and log a warning when doing so. Other than that, I guess we'll have to wait for upstream to decide how they want to properly handle this field, since as of now it's just a waste of clock cycles as far as I can tell. My patch right now only addresses the base 64 decoding issue in SHA1C parsing that everyone seems to be having, and there is more to take care of as far as DoSing with unexpected data goes. For example, a ParseError is raised when there is no xml data, but that again crashes the conversation. KeyErrors are raised when certain attributes are missing from the xml, which too crash the conversation. For upstream see bug #24138. ** Attachment added: 02_fix_malformed_sha1c.diff http://launchpadlibrarian.net/35357473/02_fix_malformed_sha1c.diff -- telepathy-butterfly crashed with TypeError in b64decode() https://bugs.launchpad.net/bugs/401028 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

Any updates on this? Bug confirmed: X61s 2.6.27-11-generic The function keys do not adjust the backlight brightness same dmesg brightness_enable=1 has no result acpitool -l adjusts brightness just fine executing: xrandr --output LVDS --set BACKLIGHT_CONTROL native makes everything function properly I've looked into the acpi events and scripts, and I don't think the problem resides there.
