Rebased and updated to not split on a space when inside a square brace. This makes specifying lists more tolerant to spaces. Added another test case that shows this. Still not seeing where in the code the SSH key is getting split apart and left in EXTRA_CMDLINE. |
Fixes rancher#2755. Allows for quoted arguments with spaces in the kernel cmdline to be parsed properly. An example command line: ``` $ cat /proc/cmdline earlyprintk=serial console=ttyS0 rancher.autologin=ttyS0 rancher.defaults.hostname=ros-vm1 rancher.defaults.network.dns.nameservers=[192.168.64.1] rancher.network.interfaces.eth0.dhcp=true rancher.network.interfaces.eth1.dhcp=false rancher.network.interfaces.eth1.address=192.168.99.11/24 rancher.state.dev=LABEL=RANCHER_STATE rancher.state.autoformat=[/dev/vda] rancher.state.formatzero cc.ssh_authorized_keys=['ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBOz8mD0tRrNsHBLHD5jVgmXO26JA7eKFZrj4Ic9KR2y3qXlxU9JCYYn/qDyTCmExt8Rw6SaU/BvgU7WT3Bjsi6c=','ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJj5mkpBHBBAW5XClcB5aFTWph+VCL7I0W8gm93AT5w4','ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDKfb0O2qXgIgrtD5Mj7fBYdg4jMrT7wetBbkG2e4maDsRR3AtSYjEB3NeEifM8gdvIf0gYs1BNB/Ar76agaQGeqW+Ewb2LWdypr4Ipw09yWCrC9ttVbCnHuzVLYjML0CNgpjIRC+FC5r1X1gm2LufRN4orZ1NQvNhRRWJVT37vRtHo79TecK0DKQmy87Zpj3cNiI/5iObnTk56pZWpIAEiC5hEVkcVxmdkLJs3YonWVZzmK/Y8uvFtF+GhA6Jcpc38zDQHKsOjFWvj3qbWtVEQteNDxsM2pNeXY5wdrhRn4YSdKme9Cm7CdAogIdAdPtqPIfq/jY0QczS12qFZH7zt'] ``` Results in: ``` $ sudo ros config export rancher: defaults: hostname: ros-vm1 network: dns: nameservers: - 192.168.64.1 environment: EXTRA_CMDLINE: /init AAAAC3NzaC1lZDI1NTE5AAAAIJj5mkpBHBBAW5XClcB5aFTWph+VCL7I0W8gm93AT5w4','ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDKfb0O2qXgIgrtD5Mj7fBYdg4jMrT7wetBbkG2e4maDsRR3AtSYjEB3NeEifM8gdvIf0gYs1BNB/Ar76agaQGeqW+Ewb2LWdypr4Ipw09yWCrC9ttVbCnHuzVLYjML0CNgpjIRC+FC5r1X1gm2LufRN4orZ1NQvNhRRWJVT37vRtHo79TecK0DKQmy87Zpj3cNiI/5iObnTk56pZWpIAEiC5hEVkcVxmdkLJs3YonWVZzmK/Y8uvFtF+GhA6Jcpc38zDQHKsOjFWvj3qbWtVEQteNDxsM2pNeXY5wdrhRn4YSdKme9Cm7CdAogIdAdPtqPIfq/jY0QczS12qFZH7zt'] network: interfaces: eth0: dhcp: true eth1: address: 192.168.99.11/24 dhcp: false state: autoformat: - /dev/vda dev: LABEL=RANCHER_STATE formatzero: true ssh_authorized_keys: - ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBOz8mD0tRrNsHBLHD5jVgmXO26JA7eKFZrj4Ic9KR2y3qXlxU9JCYYn/qDyTCmExt8Rw6SaU/BvgU7WT3Bjsi6c= - ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJj5mkpBHBBAW5XClcB5aFTWph+VCL7I0W8gm93AT5w4 - ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDKfb0O2qXgIgrtD5Mj7fBYdg4jMrT7wetBbkG2e4maDsRR3AtSYjEB3NeEifM8gdvIf0gYs1BNB/Ar76agaQGeqW+Ewb2LWdypr4Ipw09yWCrC9ttVbCnHuzVLYjML0CNgpjIRC+FC5r1X1gm2LufRN4orZ1NQvNhRRWJVT37vRtHo79TecK0DKQmy87Zpj3cNiI/5iObnTk56pZWpIAEiC5hEVkcVxmdkLJs3YonWVZzmK/Y8uvFtF+GhA6Jcpc38zDQHKsOjFWvj3qbWtVEQteNDxsM2pNeXY5wdrhRn4YSdKme9Cm7CdAogIdAdPtqPIfq/jY0QczS12qFZH7zt ```

@Jason-ZW, any thoughts on this PR? As well as, where the line splitting might still be happening resulting in leftover parts in EXTRA_CMDLINE? Thanks. |
