net: netconsole: Add continuation line prefix to userdata messages

2024-03-11T21:07:57Z

Add a space (' ') prefix to every userdata line to match docs for dev-kmsg. To account for this extra character in each userdata entry, reduce userdata entry names (directory name) from 54 characters to 53. According to the dev-kmsg docs, a space is used for subsequent lines to mark them as continuation lines. > A line starting with ' ', is a continuation line, adding > key/value pairs to the log message, which provide the machine > readable context of the message, for reliable processing in > userspace. Testing for this patch:: cd /sys/kernel/config/netconsole && mkdir cmdline0 cd cmdline0 mkdir userdata/test && echo "hello" > userdata/test/value mkdir userdata/test2 && echo "hello2" > userdata/test2/value echo "message" > /dev/kmsg Outputs:: 6.8.0-rc5-virtme,12,493,231373579,-;message test=hello test2=hello2 And I confirmed all testing works as expected from the original patchset Fixes: df03f830d099 ("net: netconsole: cache userdata formatted string in netconsole_target") Signed-off-by: Matthew Wood Reviewed-by: Breno Leitao Link: https://lore.kernel.org/r/20240308002525.248672-1-thepacketgeek@gmail.com Signed-off-by: Jakub Kicinski

Documentation: netconsole: add support for cmdline targets

2023-10-14T00:26:38Z

With the previous patches, there is no more limitation at modifying the targets created at boot time (or module load time). Document the way on how to create the configfs directories to be able to modify these netconsole targets.

netconsole: Append kernel version to message

2023-07-18T09:04:59Z

Create a new netconsole runtime option that prepends the kernel version in the netconsole message. This is useful to map kernel messages to kernel version in a simple way, i.e., without checking somewhere which kernel version the host that sent the message is using. If this option is selected, then the "," is prepended before the netconsole message. This is an example of a netconsole output, with release feature enabled: 6.4.0-01762-ga1ba2ffe946e;12,426,112883998,-;this is a test Cc: Dave Jones Signed-off-by: Breno Leitao Link: https://lore.kernel.org/r/20230714111330.3069605-1-leitao@debian.org Signed-off-by: Paolo Abeni
