…pt-fix3 update script fix #3 for fluxcd, k3s, linode-cli, linkerd

The test failed with > Test "test5 user should not be able to run commands under root" failed with > error: "invalid literal for int() with base 10: ''" since 2492da8. The reason for this is that `sudo(8)` writes the lecture to the tty[1] and only as a fallback to stdout[2]. This means that the `base64 --wrap 0` executed by `machine.execute()` doesn't affect the text written to the terminal, however the lecture is part of the string that's read from the VM via `shell.recv()`. I confirmed the problem in an interactive test session[3]: >>> command = "sudo -u test5 sudo -n -u root true" >>> out_command = f"( set -euo pipefail; {command} ) | (base64 --wrap 0; echo)\n" >>> machine.shell.send(out_command.encode()) 84 >>> machine # [ 99.015512] sudo[877]: root : TTY=hvc0 ; PWD=/tmp ; USER=test5 ; COMMAND=/run/wrappers/bin/sudo -n -u root true machine # [ 99.019373] sudo[877]: pam_unix(sudo:session): session opened for user test5(uid=1005) by (uid=0) machine # [ 99.038692] sudo[879]: pam_unix(sudo:auth): conversation failed machine # sudo: a password is required machine # [ 99.041860] sudo[879]: pam_unix(sudo:auth): auth could not identify password for [test5] machine # [ 99.046901] sudo[877]: pam_unix(sudo:session): session closed for user test5 >>> >>> x=machine._next_newline_closed_block_from_shell() >>> print(x) <newline> We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things: <newline> #1) Respect the privacy of others. #2) Think before you type. #3) With great power comes great responsibility. <newline> <newline> <newline> >>> Since the lecture isn't strictly necessary to confirm that `security.sudo` works as expected, I decided to disable lecturing inside the test, however we may want to fix the underlying problem in the test-driver at some point.

Strongly inspired by the forgejo counterpart[1], for the following reasons: * The feature is broken with the current module and crashes on authentication with the following stacktrace (with a PAM service `gitea` added): server # Stack trace of thread 1008: server # #0 0x00007f3116917dfb __nptl_setxid (libc.so.6 + 0x8ddfb) server # #1 0x00007f3116980ae6 setuid (libc.so.6 + 0xf6ae6) server # #2 0x00007f30cc80f420 _unix_run_helper_binary (pam_unix.so + 0x5420) server # #3 0x00007f30cc8108c9 _unix_verify_password (pam_unix.so + 0x68c9) server # #4 0x00007f30cc80e1b5 pam_sm_authenticate (pam_unix.so + 0x41b5) server # #5 0x00007f3116a84e5b _pam_dispatch (libpam.so.0 + 0x3e5b) server # #6 0x00007f3116a846a3 pam_authenticate (libpam.so.0 + 0x36a3) server # #7 0x00000000029b1e7a n/a (.gitea-wrapped + 0x25b1e7a) server # #8 0x000000000047c7e4 n/a (.gitea-wrapped + 0x7c7e4) server # ELF object binary architecture: AMD x86-64 server # server # [ 42.420827] gitea[897]: pam_unix(gitea:auth): unix_chkpwd abnormal exit: 159 server # [ 42.423142] gitea[897]: pam_unix(gitea:auth): authentication failure; logname= uid=998 euid=998 tty= ruser= rhost= user=snenskek It only worked after turning off multiple sandbox settings and adding `shadow` as supplementary group to `gitea.service`. I'm not willing to maintain additional multiple sandbox settings for different features, especially given that it was probably not used for quite a long time: * There was no PR or bugreport about sandboxing issues related to PAM. * Ever since the module exists, it used the user `gitea`, i.e. it had never read-access to `/etc/shadow`. * Upstream has it disabled by default[2]. If somebody really needs it, it can still be brought back by an overlay updating `tags` accordingly and modifying the systemd service config.

nixosTests.cryptpad started failing recently. Investigating the issue shows that seccomp has become problematic during the init phase, (e.g. this can be reproduced by removing the customize directory in /var/lib/cryptpad): machine # [ 10.774365] systemd-coredump[864]: Process 756 (node) of user 65513 dumped core. machine # machine # Module libgcc_s.so.1 without build-id. machine # Module libstdc++.so.6 without build-id. machine # Module libicudata.so.74 without build-id. machine # Module libicuuc.so.74 without build-id. machine # Module libicui18n.so.74 without build-id. machine # Module libz.so.1 without build-id. machine # Module node without build-id. machine # Stack trace of thread 756: machine # #0 0x00007ff951974dcb fchown (libc.so.6 + 0x107dcb) machine # #1 0x00007ff95490d0c0 uv__fs_copyfile (libuv.so.1 + 0x150c0) machine # #2 0x00007ff95490d89a uv__fs_work (libuv.so.1 + 0x1589a) machine # #3 0x00007ff954910c76 uv_fs_copyfile (libuv.so.1 + 0x18c76) machine # #4 0x0000000000eb8a39 _ZN4node2fsL8CopyFileERKN2v820FunctionCallbackInfoINS1_5ValueEEE (node + 0xab8a39) machine # #5 0x0000000001cda5e2 Builtins_CallApiCallbackGeneric (node + 0x18da5e2) [...] machine # [ 10.877468] cryptpad[685]: /nix/store/h4yhhxpfm03c5rgz91q7jrvknh596ly2-cryptpad-2024.12.0/bin/cryptpad: line 3: 756 Bad system call (core dumped) "/nix/store/fkyp1bm5gll9adnfcj92snyym524mdrj-nodejs-22.11.0/bin/node" "/nix/store/h4yhhxpfm03c5rgz91q7jrvknh596ly2-cryptpad-2024.12.0/lib/node_modules/cryptpad/scripts/build.js" nodejs 20.18 rightly did not require chown when the source and destination are the same owner (heck, the script does not run as root so even if it is not blocked there is no way it'd work with a different owner...)
