linux 4.7.2 & btrfs & rsync & OOM gone crazy

Just upgraded from 4.6.5 to 4.7.2 for my btrfs backup server with 32GB of ram. Only thing that run's on it is an rsync of an NFS filesystem to the local btrfs. Cached mem tends to hang out around 26-30GB, but with 4.7.2 the OOM is now going crazy and trying to kill whatever it can including my ssh

Hi, let me draw your attention to https://bugzilla.kernel.org/show_bug.cgi?id=153641 which is a heap-use-after-free bug in btrfs-progs v4.7-42-g56e9586 I found while fuzzing btrfs. There are more bugs like this. How do you people want them to be reported? Best regards Lukas -- To unsubscribe

Hi Chris, first off, thank you for the detailled explanations! On 2016-08-26 01:04, Chris Murphy wrote: No, it's not a file, directory or subvolume specific command. It applies to a whole volume. You are right, but all I was after in the first place was a way to change the mode for new data

Re: linux 4.7.2 & btrfs & rsync & OOM gone crazy

Interesting, thanks. Patch doesn't apply clean to 4.7.2, but I get the gist, delete one version of should_compact_retry() and move ifdef so it only has __alloc_pages_direct_compact(). I'll try it out if my rsync gets OOM'd again. On Fri, Aug 26, 2016 at 3:02 PM, Tomasz Torcz
