Hi, all Maybe this subject will re-affirm the harmony between Ariane and Theo. I hope it doesn't just raise frustration levels anyway.
I doubt it will make any devs wanting to take advantage of OpenBSDs malloc job easier by getting the ear of Mozilla but I'd be interested if anyone would like to comment on this thread from the mozilla security list? You never know it might do some good? __________________________________________________________________________ >>> On 2012-06-21 4:02 PM, Kevin Chadwick wrote: >>> >>> p.s. mozilla uses it's own malloc which is annoying because OpenBSDs is >>> so much better!!! >> >> We've done extensive tests and believe jemalloc is the best available >> malloc for the way we use memory; however, I don't know that we've >> tested specifically against OpenBSD malloc.

I wasn't directly involved, but I believe it was almost entirely performance. In contexts where malloc-related security is an overriding concern we have our own hacks -- see e.g. nsPresArena.cpp. > http://marc.info/?l=openbsd-misc&m=130687174807002&w=2 > http://marc.info/?l=openbsd-misc&m=130688429221978&w=2 I could be wrong, but I am under the impression that we do not use tagged pointers anymore. > Do you mind If I forward this request to the OpenBSD list. > We may get some more accurate and interesting answers than I can give > that way. Be my guest, but please respect follow-ups to dev.platform. zw ____________________________________________________________________________
