Subject: [Ethereal-dev] Patches to correct memory leaks

 

Attached are proposed patches to several dissectors that appear to have memory leaks due to not freeing memory allocated after calls to tvb_get_string(), tvb_get_stringz(), and tvb_fake_unicode().  Although I tried to be very cautious, it is possible that I incorrectly freed memory that wasn’t supposed to be.  One dissector in particular, packet-multipart.c, was a bit confusing to me.  And then there’s packet-wsp.c:  I kept getting lost in that one due to the many macros, etc., so perhaps the author or someone much more familiar with that source code than I could review that one to check for leaks.  It may in fact be just fine.

 

BTW: It was quite a tedious task to check for these leaks, and I fear that leaks like this will continue to creep in, even if we’ve somehow managed to find them all for the time being.  I wonder if there’s an automated way to check for leaks, such as this?  I use lint on many projects.  Has anyone used it or considered using it on the Ethereal source? 

 

Regards,

Chris
