Security updates for Thursday
Security updates have been issued by Debian (mutt), Fedora (libntlm, mingw-python-pillow, python-pillow, and sudo), Mageia (kernel), SUSE (gdk-pixbuf, perl-Convert-ASN1, samba, and yast2-multipath), and Ubuntu (linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.4, linux-hwe-5.8, linux-oracle). | | 3:56p |
[$] Avoiding blocking file-name lookups As a general rule, when one attempts to open a file with a system call like openat2(), the expectation is that the call will not return until the job is done. But there are times where the desire to open the file is conditional on being able to open it immediately, without blocking. Linux has never supported that mode well, but that may be about to change with this
patch set from Jens Axboe. | | 6:37p |
Corellium: How we ported Linux to the M1 The Corellium blog is carrying a description of how the Linux
port to the Apple M1 processor was done. " Many components of the
M1 are shared with Apple mobile SoCs, which gave us a good running
start. But when writing Linux drivers, it became very apparent how
non-standard Apple SoCs really are. Our virtual environment is extremely
flexible in terms of models it can accommodate; but on the Linux side, the
64-bit ARM world has largely settled on a well-defined set of building
blocks and firmware interfaces - nearly none of which were used on the
M1." | | 9:16p |
This is 2021: what’s coming in free/libre software (Libre Arts) Libre Arts (formerly Libre Graphics World) has posted a comprehensive
survey of what 2021 might hold for a wide range of free
content-creation software.
The topic of fullscreen color management implementation in Wayland is back,
and it’s a kinda frustrating story. In a nutshell:
- people who are now working on this (Collabora developers) seem to have
little experience with color management but they appear to be motivated to
hack on the code;
- all the while people who have a crapload of experience with color
management have had bad experience discussing this before, do not like the
approach by the new team, and don’t seem excited to contribute to this new
effort (Graeme’s spec proposal is still available).
So we might end up with an implementation that is not suitable for
professional work.
