Subject: [PATCH v8 0/4] Properly align all PT_LOAD segments with tests
Date: Tue, 18 Jan 2022 13:57:27 -0800 [thread overview]
Message-ID: <20220118215731.1320930-1-hjl.tools@gmail.com> (raw)
Changes from v7:
1. Skip non-power of two alignment when considering the maximum p_align.
2. Add tst-p_alignmod-base.c to build tst-p_alignmod-base.so with
bool
__attribute__ ((weak, noclone, noinline))
is_aligned_p (void *p, int align)
{
return (((uintptr_t) p) & (align - 1)) == 0;
}
3. Update the Copyright year.
Changes from v6:
1. Rebase.
2. Add tests for other p_align cases.
Linker may set p_align of a PT_LOAD segment larger than p_align of the
first PT_LOAD segment to satisfy a section alignment. We should align
the first PT_LOAD segment to the maximum p_align of all PT_LOAD segments.
H.J. Lu (4):
elf: Properly align all PT_LOAD segments [BZ #28676]
elf: Add a test for PT_LOAD segments with mixed p_align [BZ #28676]
elf: Add a test for PT_LOAD segments with p_align == 1 [BZ #28688]
elf: Add a test for PT_LOAD segments with invalid p_align [BZ #28688]
