[AMDGPU] Make named barrier type 1 byte to fix barrier IDs of array elements
Since #209746, a pointer in the barrier address space (15) is the barrier ID,
and the backend reads the ID as `ptr & 0x3F`. But `target("amdgcn.named.barrier", 0)`
is still 16 bytes, so GEP to element `i` of a barrier array adds `16 * i` to the
barrier ID. For example, if `@bars` gets barrier ID 1, `&bars[2]` selects barrier
33 instead of 3.
This PR changes the type to 1 byte, so one array element is one barrier ID.
Fixes LCOMPILER-2898.
NAS-144372 / 28.0.0-BETA.1 / Do not offer the SSH password method when 2FA is enabled for SSH (#19972)
The SSH password method can send only one answer, so it always fails
when a one-time code is also required. Some clients try that method
first. After that failed attempt sshd closed the connection even when
the user then entered a correct password and code. sshd now offers only
the keyboard-interactive method to these users. That method still asks
for both the password and the code.
This was seen by an internal tester using `mobaxterm` as their ssh
client. It presented this very confusing scenario
```
09/10/2026 08:19.25 /home/mobaxterm ssh truenas_admin at truenas.blah
truenas_admin at truenas.blah's password:
truenas_admin at truenas.blah's password:
truenas_admin at truenas.blah's password:
(truenas_admin at truenas.blah) password:
(truenas_admin at truenas.blah) One-time password (OATH) for `truenas_admin':
Connection to truenas.blah closed by remote host.
Connection totruenas.blah closed.
