2023-03-21bootconfig: Fix testcase to increase max nodeMasami Hiramatsu (Google)1-4/+8
Since commit 6c40624930c5 ("bootconfig: Increase max nodes of bootconfig from 1024 to 8192 for DCC support") increased the max number of bootconfig node to 8192, the bootconfig testcase of the max number of nodes fails. To fix this issue, we can not simply increase the number in the test script because the test bootconfig file becomes too big (>32KB). To fix that, we can use a combination of three alphabets (26^3 = 17576). But with that, we can not express the 8193 (just one exceed from the limitation) because it also exceeds the max size of bootconfig. So, the first 26 nodes will just use one alphabet. With this fix, test-bootconfig.sh passes all tests.

2020-11-19tools/bootconfig: Align the bootconfig applied initrd image size to 4Masami Hiramatsu1-1/+5
Align the bootconfig applied initrd image size to 4. To fill the gap, the bootconfig command uses null characters in between the bootconfig data and the footer. This will expands the footer size but don't change the checksum. Thus the block image of the initrd file with bootconfig is as follows. [initrd][bootconfig][(pad)][size][csum]["#BOOTCONFIG\n"] Link: https://lkml.kernel.org/r/160576522046.320071.8550680670010950634.stgit@devnote2 Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

Add append value operator "+=" support to bootconfig syntax. With this operator, user can add new value to the key as an entry of array instead of overwriting. For example, foo = bar ... foo += baz Then the key "foo" has "bar" and "baz" values as an array.

2020-02-21bootconfig: Add bootconfig magic word for indicating bootconfig explicitlyMasami Hiramatsu1-1/+1
Add bootconfig magic word to the end of bootconfig on initrd image for indicating explicitly the bootconfig is there. Also tools/bootconfig treats wrong size or wrong checksum or parse error as an error, because if there is a bootconfig magic word, there must be a bootconfig. The bootconfig magic word is "#BOOTCONFIG\n", 12 bytes word. Thus the block image of the initrd file with bootconfig is as follows. [Initrd][bootconfig][size][csum][#BOOTCONFIG\n] Link: http://lkml.kernel.org/r/158220112263.26565.3944814205960612841.stgit@devnote2 Suggested-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
