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

2026-03-25T10:13:32+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.

bootconfig: Fix negative seeks on 32-bit with LFS enabled

2025-08-20T23:16:31+00:00

Commit 26dda5769509 "tools/bootconfig: Cleanup bootconfig footer size calculations" replaced some expressions of type int with the BOOTCONFIG_FOOTER_SIZE macro, which expands to an expression of type size_t, which is unsigned. On 32-bit architectures with LFS enabled (i.e. off_t is 64-bit), the seek offset of -BOOTCONFIG_FOOTER_SIZE now turns into a positive value. Fix this by casting the size to off_t before negating it. Just in case someone changes BOOTCONFIG_MAGIC_LEN to have type size_t later, do the same thing to the seek offset of -BOOTCONFIG_MAGIC_LEN.

bootconfig: Fix unaligned access when building footer

2025-07-24T13:16:48+00:00

Currently we add padding between the bootconfig text and footer to ensure that the footer is aligned within the initramfs image. However, because only the bootconfig data is held in memory, not the full initramfs image, the footer may not be naturally aligned in memory. This can result in an alignment fault (SIGBUS) when writing the footer on some architectures, such as sparc. Build the footer in a struct on the stack before adding it to the buffer.

tools/bootconfig: Cleanup bootconfig footer size calculations

2025-07-14T02:56:11+00:00

There are many same pattern of 8 + BOOTCONFIG_MAGIC_LEN for calculating the size of bootconfig footer. Use BOOTCONFIG_FOOTER_SIZE macro to clean up those magic numbers.

tools/bootconfig: Replace some echo with printf for more portability

2025-07-14T02:55:58+00:00

Since echo is not portable, use printf instead. This fixes a wrong test result formatting in some environment. (showing "\t\t[OK]") Also this uses printf command for generating test data instead of echo.
