Fix the bind-now case when DT_REL and DT_JMPREL sections are separate and there is a gap between them. [BZ #14341] * elf/dynamic-link.h (elf_machine_lazy_rel): Properly handle the case when there is a gap between DT_REL and DT_JMPREL sections. * sysdeps/x86_64/Makefile (tests): Add tst-split-dynreloc. (LDFLAGS-tst-split-dynreloc): New. (tst-split-dynreloc-ENV): Likewise. * sysdeps/x86_64/tst-split-dynreloc.c: New file. * sysdeps/x86_64/tst-split-dynreloc.lds: Likewise.

/* This test will be used to create an executable with a specific
|
|
section layout in which .rela.dyn and .rela.plt are not contiguous.
|
|
For x86 case, readelf will report something like:
|
|
|
|
...
|
|
[10] .rela.dyn RELA
|
|
[11] .bar PROGBITS
|
|
[12] .rela.plt RELA
|
|
...
|
|
|
|
This is important as this case was not correctly handled by dynamic
|
|
linker in the bind-now case, and the second section was never
|
|
processed. */
