tools/bootconfig: fix fd leak in load_xbc_file() on fstat failure

2026-03-25T10:06:10+00:00

[ Upstream commit 3b2c2ab4ceb82af484310c3087541eab00ea288b ] If fstat() fails after open() succeeds, the function returns without closing the file descriptor. Also preserve errno across close(), since close() may overwrite it before the error is returned.

[ Upstream commit f6ab7384d554ba80ff4793259d75535874b366f5 ] Use '%u' instead of '%d' for unsigned int.

bootconfig: Cleanup dummy headers in tools/bootconfig

2021-10-11T02:16:02+00:00

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

2021-10-11T00:44:05+00:00

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

2021-10-11T00:44:05+00:00

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()

2021-10-11T00:44:05+00:00

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

2021-10-11T00:43:53+00:00

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()

2021-10-11T00:43:42+00:00

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

2021-09-08T19:28:50+00:00

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.

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)
