Someone asked me to sign their gpg key so I did. Am I doing this gpg thing right?

@ffmancera@mastodon.social @ptesarik@infosec.exchange you need to eventually remove ipv4 completely
Replying to
@bert_hubert@eupolicy.social that's cool!

@gabrielesvelto @vathpela @guenther Linux kernel has CONFIG_SHUFFLE_PAGE_ALLOCATOR to randomize which memory gets allocated first, which generally distros enable, but probably no one activates it by the boot param page_alloc.shuffle=y ;)

@bert_hubert@eupolicy.social so Pat & Mat are known in the Netherlands too? Cool!

@ljs@mastodonapp.uk @monsieuricon@social.kernel.org finally! I've been telling you that only for a year or so.
BTW there was a hater making fun of the "Best regards" in the cover letter, saying it's hardcoded. But he can eat his words now! https://lore.kernel.org/all/20260710-bulk_free_remote-v1-1-a878d6dc52d5@kernel.org/

@ljs@mastodonapp.uk @monsieuricon@social.kernel.org no I figured it independently 2 days ago but was waiting for an opportunity to send a patch. You beat me to it :)

@ffmancera @ptesarik @ljs @hyeyoo do you know that P in that acronym stands for Post, i.e. something that happened in the past and is not happening anymore.

Ugh, the whole afternoon spent digging in 5.14-based kernel's proactive compaction code. With no great findings.

@ozzelot@mstdn.social @prahou@merveilles.town what about his younger brother io_uriel
Replying to
@vaurora @ljs @ffmancera @ptesarik @hyeyoo hehe I never really watched it, but was aware some CZ TV aired it, perhaps around 2000 or something.
Replying to
@vathpela @oleksandr @gabrielesvelto @guenther it's meant for hardening and there's some performance trade-off, which is typical. But IMHO it's better if hardening options can be enabled just by boot parameters and not require a different distro kernel flavor.

@monsieuricon except some are breaking various scripts and the kernel.org web? ;)

@kernellogger > We already have a sysctl for it, and you should already be able to
use a boot parameter for it with just
sysctl.kernel.panic_on_rcu_stall=true
You're welcome, Linus! Hm I wonder when was the last time I actually used this myself lol.

@hyeyoo @kernellogger haha you improved upon it a lot!

@josefbacik@hachyderm.io Josef Bacik, a prominent Btrfs engineer at Meta, wrote about the magnitude of impact for Meta's Btrfs usage, then proceeded to quit Btrfs, Meta, kernel.
You'll be missed :(

@liskin so according to @ffmancera the future is Kofola?

@airlied I'd suggest cc'ing the memcg maintainers directly in case they don't read the ML regularly :)

@thesamesam @tomasv @AndresFreundTec @mgorny is it known if the reporter provided the info that it's that serious, or even the exploit? From various tidbits I thought they didn't.
Replying to
@tychotithonus@infosec.exchange I think it rather should be illegal for those kinds of public posters to use platforms that require login?

@kernellogger yes and the best way to test is on wife's laptop, cc: @oleksandr

@lkundrak@metalhead.club @josefbacik@hachyderm.io IIRC they used to give talks about Btrfs with Chris Mason where Chris gave the "god cop" part and Josef the "bad cop" part.

@vegard is this coincidence, sir?
