[Bug 169048] Crashes when applying all filters on IMAP folder [KMail::ActionScheduler::actionMessage, KMail::ActionScheduler::filterMessage]
https://bugs.kde.org/show_bug.cgi?id=169048 Siu Chung (Clement) Cheung clement...@gmail.com changed: What|Removed |Added CC||clement...@gmail.com --- Comment #25 from Siu Chung (Clement) Cheung clement cc gmail com 2010-06-11 23:32:32 --- Hi, This crash is due to you all having a rule with no actions but having stop processing here to make certain emails immune to subsequent rules. (see Michal's filter #1) Kmail currently chokes on that. I have already debugged this crash and attached a fix in bug 169646. Please see comments and attachment there for full explanation of this crash. I notice now that the bug is already closed when I posted due to lack of feedback, which is probably why nobody noticed my patch. Sorry about that. Should have searched more. Can someone try my patch and see if it works for you and maybe have someone from the kmail team take a look? There have been so many reports of this bug already. The crash is fully reproducible. But you must have *NEW* email matching the no action rule to trigger this crash. So if you rerun kmail immediately after the crash, it no longer happens due to the mail being no longer new. This is probably why people are saying the crash is random. To reproduce the bug consistently, simply make a no action rule matching your own email address and send an email to yourself. As a workaround, add a sound action to your empty rule. If you find the barrage of sound annoying, simply record one second of silence and use that as your sound. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ Kdepim-bugs mailing list Kdepim-bugs@kde.org https://mail.kde.org/mailman/listinfo/kdepim-bugs
[Bug 169646] Kmail crashes when applying filter with no rules
https://bugs.kde.org/show_bug.cgi?id=169646 Siu Chung (Clement) Cheung clement...@gmail.com changed: What|Removed |Added CC||clement...@gmail.com --- Comment #4 from Siu Chung (Clement) Cheung clement cc gmail com 2010-04-17 05:41:45 --- This bug is still happening. kmail 1.13.2 KDE 4.4.2 linux kernel 2.6.33-gentoo-r1 (x86_64) Gentoo packages. Interestingly, my other setup with 32-bit linux on Sabayon Linux doesn't crash using exact same rule. Not sure why. Backtrace: Thread 1 (Thread 0x7f457240c750 (LWP 11155)): [KCrash Handler] #5 0x7f4570dbfb62 in KMail::ActionScheduler::actionMessage(KMFilterAction::ReturnCode) () from /usr/lib64/libkmailprivate.so.4 #6 0x7f4570dbfe1a in KMail::ActionScheduler::filterMessage() () from /usr/lib64/libkmailprivate.so.4 #7 0x7f4570dc05ba in KMail::ActionScheduler::qt_metacall(QMetaObject::Call, int, void**) () from /usr/lib64/libkmailprivate.so.4 #8 0x7f456ccb7147 in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) () from /usr/lib64/qt4/libQtCore.so.4 #9 0x7f456ccb3bd3 in QObject::event(QEvent*) () from /usr/lib64/qt4/libQtCore.so.4 Liberal sprinkling of debug statements in the area reveals that the variable action is pointing at 0x21, an invalid but non-zero address which passes the mFilterAction check in actionMessage(). This causes a segfault when accessed later. How does that happen? Here's the current code that checks for the end of the action list: 498 KMFilterAction *action = mFilterAction; 499 // mFilterAction = (*mFilterIt).actions()-next(); 500 if ( ++mFilterActionIt == (*mFilterIt)-actions()-end() ) 501 mFilterAction = 0; 502 else mFilterAction = (*mFilterActionIt); 503 action-processAsync( *mMessageIt ); 504 } The problem is we're checking if the *NEXT* action is the end. What about the *CURRENT* one? Sure it's supposed to be already checked when we advance the pointer there. Except that the first action isn't assigned by this iterator advancing code. It's initialized in filterMessage(): mFilterActionIt = (*mFilterIt)-actions()-begin(); mFilterAction = (*mFilterActionIt); actionMessage(); What's happening here is that begin() == end() since the list is empty. We didn't verify that mFilterActionIt isn't end (and therefore invalid) before dereferencing it. Since this is an iterator, not a pointer, we won't crash -- yet. But mFilterAction will get random garbage. If said random garbage happens to be non-zero, actionMessage() will then try to dereference it as a pointer and hence the crash. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ Kdepim-bugs mailing list Kdepim-bugs@kde.org https://mail.kde.org/mailman/listinfo/kdepim-bugs
[Bug 169646] Kmail crashes when applying filter with no rules
https://bugs.kde.org/show_bug.cgi?id=169646 --- Comment #6 from Siu Chung (Clement) Cheung clement cc gmail com 2010-04-17 05:54:55 --- As a temporary work around, people like me who need this to set a stop processing here rule with no action and matching sender = my_b...@my_company.com to make sure important messages doesn't get filtered can assign a sound as action. That action will have no effect except being extremely irritating when a whole bunch of messages matching the rule arrives. This can be avoided by recording a wav file of silence and using it as the action. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ Kdepim-bugs mailing list Kdepim-bugs@kde.org https://mail.kde.org/mailman/listinfo/kdepim-bugs
