[llubi] Treat `llvm.experimental.noalias.scope.decl` as a noop (#206357)
The noalias support is still work in progress:
https://github.com/llvm/llvm-project/pull/195808
`llvm.experimental.noalias.scope.decl` is emitted by the inliner. We may
need more time to clarify the semantics.
This patch treats the intrinsic as a noop to avoid crashes (metadata
arguments are not supported before this patch).
The openHAB user needs to be able to write to a few more files under
/var/db/openhab/etc.
And the users.properties file contains secrets, so change mode 0640

nuageinit: validate set-name to prevent shell injection in variable names
Shell variable names cannot be safely quoted with shell_escape() —
only alphanumeric characters are valid. Add validation that set-name
only matches [a-zA-Z0-9]+; invalid values are rejected with a
warning and the rename is skipped entirely.

nuageinit: use single-quote shell escaping for hostname in rc.conf.d
The hostname value was written inside double quotes in
/etc/rc.conf.d/hostname. POSIX shell performs command substitution
inside double quotes, so a hostname containing $() or backticks would
be executed when the file is sourced (e.g., by rc(8)).
Switch to using the existing shell_escape() helper, which wraps values
in single quotes. In POSIX shell, single-quoted strings are completely
literal — no expansion or substitution of any kind is performed.
While the hostname is already validated to contain only
[a-zA-Z0-9.-], this change provides defense-in-depth so the output
format is safe regardless of future validation changes.

[InstCombine] Create new instructions instead of in-place operand replacement (#115988)
Fixes https://github.com/llvm/llvm-project/issues/115890.
Currently it doesn't affect final codegen. But we may suffer from this
problem when we utilize these attributes for further optimization (e.g.,
https://github.com/llvm/llvm-project/pull/111284). This test case is
reduced from a csmith-generated C program. And I believe this problem
also exists in real-world programs.
nuageinit: implement phone_home support
Posts instance data (hostname, instance_id, public keys) to a URL
using fetch(1). Supports:
- url: target URL
- post: list of data items to send, or 'all'
- tries: number of retry attempts (default 1)
(cherry picked from commit 58653bf4d0fb8ccd5de146d671ec101a1df0ede0)
nuageinit: implement MIME multipart user-data support
Add support for MIME multipart/mixed user-data, allowing a single
user-data blob to contain multiple parts with different content types.
(cherry picked from commit be711ade6f66506fb2cae9fd33b142ce910f0346)
