A large pile of stable kernels Greg Kroah-Hartman has released the 5.11.3, 5.10.20, 5.4.102, 4.19.178, 4.14.223, 4.9.259, and 4.4.259 stable kernels. These are generally enormous updates, with important changes throughout the kernel tree; users should upgrade. | | 5:42p |
A warning about 5.12-rc1
Linus Torvalds has sent out a note telling people not to install the recent
5.12-rc1 development kernel; this is especially true for anybody running
with swap files. "But I want everybody to be aware of because _if_
it bites you, it bites you hard, and you can end up with a filesystem that
is essentially overwritten by random swap data. This is what we in the
industry call 'double ungood'." Additionally, he is asking
maintainers to not start branches from 5.12-rc1 to avoid future situations where
people land in the buggy code while bisecting problems. | | 6:04p |
[$] BPF meets io_uring Over the last couple of years, a lot of development effort has gone into two kernel subsystems: BPF and io_uring. The BPF virtual machine allows programs from user space to be safely run within the context of the kernel, while io_uring addresses the longstanding problem of running system calls asynchronously. As the two subsystems expand, it was inevitable that the two would eventually meet; the first encounter happened in mid-February with this patch
set from Pavel Begunkov adding the ability to run BPF programs from within io_uring. |
