However, on -architectures that generates the .eh_frame section with the SEC_RELOC -flag set, this section will now be placed in the text output section. - -The logic in elf2flt will handle all sections in order, and since the -input order is .text, .data, and .eh_frame, putting .eh_frame in text -output section does not work, since elf2flt.c has already put the .data -input section in the bFLT data output section. This leads to the -following print (example for riscv64 architecture): - -buildroot/output/host/riscv64-buildroot-linux-uclibc/bin/elf2flt: -ERROR: text=0x3bab8 overlaps data=0x33f60 ? - -The way that elf2flt is written, we cannot append to the text output -section after an input section has been added to the data output -section. It might be possible to change this, but that would require -moving all the code the was already placed in the data output section. - -Instead, let's allow putting a read-only relocation data section in the -text output section (so that .ARM.exidx will still be placed correctly), -but only if there has not yet been anything placed in the data output -section. - -That way .ARM.exidx will still be placed correctly, and .eh_frame will -be placed correctly in the .data output section, regardless if it has -flag SEC_RELOC set or not. - -Fixes: ba379d08bb7 ("elf2flt: fix for segfault on some ARM ELFs") -Signed-off-by: Damien Le Moal -Signed-off-by: Niklas Cassel ---- - elf2flt.c | 5 +++-- - 1 file changed, 3 insertions(+), 2 deletions(-) - -diff --git a/elf2flt.c b/elf2flt.c -index 7ac0617..da25e93 100644 ---- a/elf2flt.c -+++ b/elf2flt.c -@@ -1877,8 +1877,9 @@ int main(int argc, char *argv[]) - bfd_vma sec_vma; - - if ((s->flags & SEC_CODE) || -- ((s->flags & (SEC_DATA | SEC_READONLY | SEC_RELOC)) == -- (SEC_DATA | SEC_READONLY | SEC_RELOC))) { -+ (((s->flags & (SEC_DATA | SEC_READONLY | SEC_RELOC)) == -+ (SEC_DATA | SEC_READONLY | SEC_RELOC)) && -+ !data_len)) { - vma = &text_vma; - len = &text_len; - } else if (s->flags & SEC_DATA) { --- -2.35.1 -
