Status: RESOLVED WORKSFORME

Attachment: NSPR_LOG_nsSocketTransport

Sockets are not working for me with an optimized (-O1 -g) ASan enabled build.
Everything works fine with a non-opt ASan build though.

This also includes WebSocket support etc:

WARNING: unable to continue without random number generator: file /Users/cdiehl/Code/Mozilla/mc-asan-opt/netwerk/protocol/websocket/WebSocketChannel.cpp, line 2475

I don't know what an asan build is, how to make one, or why it matters. help?

Comment 2

[Christoph Diehl [:posidron]]

ASan is a memory error detector, you can find the instructions here:
https://developer.mozilla.org/en-US/docs/Building_Firefox_with_Address_Sanitizer

decoder is our ASan maintainer he is already CCed.

[Christian Holler (:decoder)]

I wouldn't know any reason why this should behave differently in an ASan build. I also can't see anything immediately obvious from the log.

Comment 4

[Christoph Diehl [:posidron]]

-O1 opt debug builds without ASan are working properly but not with ASan enabled.

[Brian Smith (:briansmith, :bsmith, use NEEDINFO?)]

See bug 799572. We seem to have found at least one bug in clang. Maybe this is another clang bug.

mcmanus: http://www.chromium.org/developers/testing/addresssanitizer

Our security assurance people (and others) build Firefox with ASAN to find memory corruption bugs (use after free, etc.).

Comment 6

[Christian Holler (:decoder)]

Good point. Christoph, can you try your build settings without -faddress-sanitizer though? However, OSX builds are always done with Clang, so it must be more than just the fact that Clang is used to compile. Or your version of Clang is different from the one on try :)

Comment 7

[Christoph Diehl [:posidron]]

I am using clang r161442 for ASan builds and 'Apple clang version 4.0 (tags/Apple/clang-421.0.60) (based on LLVM 3.1svn)' for native builds.

Without -faddress-sanitizer in CXX flags the build runs fine.

[Christoph Diehl [:posidron]]

Problem solved, needed to update clang to r164411 and everything works fine.
