OpenSSH 8.6 released
OpenSSH 8.6 is now available. The "ssh-rsa" signature scheme, which uses
the SHA-1 hash algorithm, will be disabled by default in the near
future. "Note that the deactivation of "ssh-rsa" signatures does not
necessarily require cessation of use for RSA keys. In the SSH protocol,
keys may be capable of signing using multiple algorithms. In particular,
"ssh-rsa" keys are capable of signing using "rsa-sha2-256" (RSA/SHA256),
"rsa-sha2-512" (RSA/SHA512) and "ssh-rsa" (RSA/SHA1). Only the last of
these is being turned off by default." |

[$] Btrfs on zoned block devices Zoned
block devices have some unfamiliar characteristics that result from compromises made in the name of higher storage density. They are divided into zones, some or all of which do not support random access for write operations. Instead, these "sequential" zones can only be written in order, from the first block to the last. This constraint poses a new challenge for filesystems, which are normally designed with the assumption that storage blocks can be written in any order. It is thus not surprising that zoned-device support in mainstream filesystems in Linux has been slow in coming; that is changing, though, with the additionof support for zoned block devices to Btrfs in Linux 5.12.</p> |
