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.
Version 0.15.1.
get_package_proxy() is what apt-config dump says, not 00proxy alone: a
proxy in 90curtin-aptproxy or /etc/apt/apt.conf wins over it and was
missed. The driver now supplies only the transports: reads on the exec
channel, root commands through _root_outcome, the file through the staged
_install_file_as_root. New: get_package_proxy_report() and
check_package_proxy(). configure_package_proxy() also comments out other
proxy lines, reads the result back and fetches through the proxy.
Requires napalm-device-types 4.22.0; version 0.14.0.
- CI moves to .gitea/workflows/ci.yml and calls the shared driver workflow
of NAPALM/driver-standard; napalm-device-types comes from git until it is
on PyPI.
- requires-python >=3.10 (napalm-device-types needs it), LICENSE file,
py.typed, SPDX license string, links to git.netork.io.
- mypy strict for the package; napalm_linux.linux is exempt for now (21
errors), recorded in the quality baseline with its long functions and
the 2200-line module. Coverage floor 58 % (measured 58.23 %).
Mixes in napalm-device-types' HostFirewallMixin. The transport runs the shared
read-only command as root on an exec channel: nft prints the whole ruleset as
one line of JSON, longer than the PTY takes reliably, and both nft and
iptables-save need CAP_NET_ADMIN. Requires napalm-device-types 4.21.0;
version 0.13.0.
Mixes in napalm-device-types' ServicePackagesMixin. The transport runs the
shared read-only command on an exec channel under sh, without sudo: it is
about 1 kB, past what the PTY takes reliably, and written for sh whatever
the login shell. Requires napalm-device-types 4.20.0; version 0.12.0.
The driver accepted any SSH host key. It now verifies through
napalm-device-types' HostKeyCheck (>= 4.19.0): with a known key in
optional_args["ssh_host_keys"] any other key is refused before login, and
every key seen is reported to optional_args["ssh_host_key_observer"].
Without either argument it connects as before (first use).
get_device_warnings decided two things for the application: that any
pending update is a warning (it re-read the updates for that), and
whether apt's proxy is the one the application's setting wants, which
it was handed as optional_args["apt_proxy_url"].
The driver reports facts instead (napalm-device-types 4.14):
get_package_proxy() says which proxy apt fetches through, None for none
or on a non-apt host; the updates are get_available_updates() as
before. get_device_warnings and the apt_proxy_url argument go.
BREAKING CHANGE: get_device_warnings and optional_args["apt_proxy_url"]
are removed. Requires napalm-device-types 4.14.
Closes#28
Mixes in napalm-device-types 4.9's SystemIdentityMixin: the host's
SMBIOS system UUID, product serial and board serial, read as root on an
exec channel, vendor placeholders empty. netOrk links a server's BMC to
the host on these.
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.
Now that a whole _sudo line runs as root, `mv /tmp/netork_snmpd.conf
/etc/snmp/snmpd.conf && chown root:root … && chmod 644 …` would have let a
local user plant a symlink at the fixed /tmp path and have root's chown and
chmod follow it (e.g. to /etc/shadow). The same held for 00proxy.
_install_file_as_root stages the content unprivileged in a fresh mktemp file
(umask 077), checks the path it got back, and root installs it as a new
regular file next to the target and renames it over: nothing root runs
follows a symlink or changes the owner or mode of an existing path. Nothing
runs as root when staging failed.
get_vpn_tunnels always reads `wg show all dump` from the exec channel; the
predictable /tmp/.netork_wg_<hash> file holding the private keys is gone.
_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.
run_command(privileged=True, stdin=data) sent `sudo -S` with stdin =
<sudo password>\n + data. A sudo that does not prompt (NOPASSWD, a cached
timestamp) leaves the password line on stdin, and the command reads it as
the first line of the data - `cat > file` wrote it into the file
(NetOrk/netork#1029).
run_command now raises ValueError for that combination before opening a
channel. Stdin still reaches the command under `sudo -n` (no password set),
for a root login, and for unprivileged commands. Callers stage the data
without privilege and have root install the file. open_stream documents the
same caveat.
LinuxDriver mixes in napalm-device-types' VirtualIpsMixin (4.2.0) and
carries its command on the exec channel: with the awk filter it is about
4 kB, past the line the PTY netmiko holds reliably takes. Root first,
then without it (NetOrk/netork#829).
Version 0.4.0.
get_docker_info(), get_docker_outdated(), reconstruct_docker_run() and
the _docker_bin() hook go, with the image-ID helpers. netOrk reads and
handles containers over the Engine API through open_container_engine()
since NetOrk/netork#765 and no longer calls them (phase 9). The
fix_docker_permissions action stays: it is an OS action.
Version 0.3.0.
netOrk drove this driver's shell through the private `_send` (an
interactive PTY, stdout and stderr merged, no exit code) and opened its
own paramiko connections for Docker. napalm-device-types 2.6.0 makes the
channel public; this implements it (NetOrk/netork#765):
- `run_command()` and `open_stream()` open an exec channel on the SSH
transport netmiko already holds: no second login, no PTY, a real exit
status.
- `privileged=True` follows the driver's existing rules: as root the
command runs directly; with a sudo password it goes through
`sudo -S -p ''` and the password is written to stdin, never onto the
command line; without one `sudo -n` fails at once instead of hanging.
- `ContainerEngineMixin` is mixed in, so `open_container_engine("docker")`
streams the Engine API over `docker system dial-stdio`.
The existing Docker methods are unchanged. Version 0.2.0, requires
napalm-device-types >= 2.6.0.
