bootconfig: Cleanup dummy headers in tools/bootconfig

2021-10-11T02:16:02Z

Cleanup dummy headers in tools/bootconfig/include except for tools/bootconfig/include/linux/bootconfig.h. For this change, I use __KERNEL__ macro to split kernel header #include and introduce xbc_alloc_mem() and xbc_free_mem().

bootconfig: Replace u16 and u32 with uint16_t and uint32_t

2021-10-11T00:44:05Z

Replace u16 and u32 with uint16_t and uint32_t so that the tools/bootconfig only needs . Link: https://lkml.kernel.org/r/163187298835.2366983.9838262576854319669.stgit@devnote2 Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt (VMware)

tools/bootconfig: Print all error message in stderr

2021-10-11T00:44:05Z

Print all error message in stderr. This also removes unneeded tools/bootconfig/include/linux/printk.h. Link: https://lkml.kernel.org/r/163187298106.2366983.15210300267326257397.stgit@devnote2 Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt (VMware)

bootconfig: Rename xbc_destroy_all() to xbc_exit()

2021-10-11T00:44:05Z

Avoid using this noisy name and use more calm one. This is just a name change. No functional change. Link: https://lkml.kernel.org/r/163187295918.2366983.5231840238429996027.stgit@devnote2 Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt (VMware)

bootconfig: Add xbc_get_info() for the node information

2021-10-11T00:43:53Z

Add xbc_get_info() API which allows user to get the number of used xbc_nodes and the size of bootconfig data. This is also useful for checking the bootconfig is initialized or not.

bootconfig: Allocate xbc_data inside xbc_init()

2021-10-11T00:43:42Z

Allocate 'xbc_data' in the xbc_init() so that it does not need to care about the ownership of the copied data. Link: https://lkml.kernel.org/r/163177339986.682366.898762699429769117.stgit@devnote2 Suggested-by: Steven Rostedt Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt (VMware)

bootconfig: Fix missing return check of xbc_node_compose_key function

2021-09-08T19:28:50Z

The function `xbc_show_list should` handle the keys during the composition. Even the errors returned by the compose function. Instead of removing the `ret` variable, it should save the value and show the exact error. This missing variable is causing a compilation issue also.

bootconfig: Share the checksum function with tools

2021-06-10T17:41:26Z

Move the checksum calculation function into the header for sharing it with tools/bootconfig. Link: https://lkml.kernel.org/r/162262197470.264090.16325743685807878807.stgit@devnote2 Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt (VMware)

bootconfig: Support mixing a value and subkeys under a key

2021-06-10T17:41:26Z

Support mixing a value and subkeys under a key. Since kernel cmdline options will support "aaa.bbb=value1 aaa.bbb.ccc=value2", it is better that the bootconfig supports such configuration too. Note that this does not change syntax itself but just accepts mixed value and subkeys e.g. key = value1 key.subkey = value2 But this is not accepted; key { value1 subkey = value2 } That will make value1 as a subkey. Also, the order of the value node under a key is fixed. If there are a value and subkeys, the value is always the first child node of the key. Thus if user specifies subkeys first, e.g. key.subkey = value1 key = value2 In the program (and /proc/bootconfig), it will be shown as below key = value2 key.subkey = value1 Link: https://lkml.kernel.org/r/162262194685.264090.7738574774030567419.stgit@devnote2 Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt (VMware)

bootconfig: Change array value to use child node

2021-06-10T17:38:25Z

It is not possible to put an array value with subkeys under a key node, because both of subkeys and the array elements are using "next" field of the xbc_node. Thus this changes the array values to use "child" field in the array case. The reason why split this change is to test it easily.
