Backport of the 0.15.1 fix onto 0ba5081, the commit netOrk pins, which
cannot take 0.15.x before it moves to napalm-device-types 4.22.
systemd 258 (Ubuntu 26.04) ships /etc/profile.d/80-systemd-osc-context.sh:
an interactive bash wraps every command in OSC 3008 sequences from PS0 and
PROMPT_COMMAND, each with a fresh UUID. They ended up in every value read
through netmiko's shell, and because the prompt never looked the same twice,
the prompt line stayed in the output too. os_version grew past 255
characters and netOrk could not store the poll.
The session now unsets PS0 and PROMPT_COMMAND right after switching the
history off and reads its prompt anew; _send() strips terminal codes from
what it returns.
napalm-device-types 4.7 changed three things this driver depends on:
- parse_dnf_security needs the "__DNF_RC=<status>" line that
DNF_SECURITY_COMMAND prints and raises ValueError without it or when dnf
failed. The yum security query had no such line, so listing updates on
any yum host raised. _YUM_SECURITY_COMMAND now prints the marker the same
way ("{ ...; echo __DNF_RC=$?; } | cat"). _rpm_security_names checks
__DNF_RC itself and turns a failed query, or output cut short before the
marker, into None (security unknown) rather than "no advisories" or an
exception.
- OSDriver.get_users was renamed to get_os_users, since NAPALM's own
get_users has another shape. LinuxDriver.get_users is now get_os_users
with the same return value.
- run_on_transport reads an exec channel to EOF after its exit status
arrives; the tests' fake channels gain recv/recv_stderr for that.
Require napalm-device-types>=4.7.1 and bump the version to 0.6.0.
_sudo typed `echo '<password>' | sudo -S -p "" <command>` into netmiko's
interactive shell. bash kept it in its history, so every poll wrote the sudo
password into the login user's ~/.bash_history, and while the command ran it
was in the process list for every local user (NetOrk/netork#1039).
_sudo, _sudo_status and _run_privileged with a password now run on an exec
channel like run_command(privileged=True): the password reaches sudo -S on
stdin, there is no PTY to echo it, and the script starts with
`exec </dev/null` so a non-prompting sudo leaves it unread. The whole
command runs as root in one sh -c - before, only the part up to the first
`;`, `&&` or `|` did. The exit status comes from the channel.
The interactive session switches its history off before its first command.
get_vpn_tunnels with a password reads `wg show all dump` from the exec
channel instead of a temp file that held the private keys.
