before the commit (a89297f08cda5ca48d21088891150e7ccc9ddac3) the system would
report:
COPY relocations don't point into .bss or .sbss section
Now, it often reports:
file offsets not monotonically increasing
This was tracked down (using this debug code) to the .gnu.conflict section
being added. In one example the offset ranges ended up being:
../src/prelink: section 15 .fini file offset range 000012f4 and 000012fd
../src/prelink: section 16 .gnu.conflict file offset range 00001300 and 00002080
../src/prelink: section 17 .rodata file offset range 00002000 and 000020a3
../src/prelink: section 18 .eh_frame_hdr file offset range 000020a4 and 00002118
This indicates that the new .gnu.conflict section overwrites .rodata by 0x80
bytes.
This commit includes a check and error return for this condition.

The info->resolvetls might be NULL according to src/prelink.c:
[snip]
/* Dynamic linker does not depend on any other library,
all symbols resolve to themselves with the exception
of SHN_UNDEF symbols which resolve to 0. */
if (info->symtab[r_sym].st_shndx == SHN_UNDEF)
{
info->resolveent = NULL;
info->resolvetls = NULL;
[snip]
So we must check it before use its members, otherwise, there might be
Segmentation fault error.
Fixed:
MACHINE = "qemumips"
IMAGE_INSTALL_append = " qemu"

COPY relocs are fine to have in PIE executables (as opposed to
shared libraries).
By enabling prelink on PIEs we achieve a few goals:
- prelink more PIE files on system: nicer for uniformity,
- avoid spurious warnings about shared libraries with COPY relocs
It's usefult to prelink PIEs when kernel ASLR is disabled:
kernel.randomize_va_space=0 + PIE-randomization patches.
I have gcc built as `--enable-default-pie` (generates PIE
executables by default).

Before the change one test failed due to timestamp drift:

This happens because prelinking takes time on the file

binutils-2.28 (17026142ef35b62ac88bfe517b4160614902cb28) adds support
for copying read-only dynamic symbols into .data.rel.ro instead of .bss
since .bss is technically writable. This causes prelink to error out on
any binary containing COPY relocations in .data.rel.ro.
Read-only variables defined in shared libraries should be copied directly
into the space allocated for them in .data.rel.ro by the linker.
To achieve this, we determine whether either of the two sections
containing copy relocations is .data.rel.ro. If so, we relocate the
symbol memory directly into the existing section instead of constructing
a new .(s)dynbss section once prelink_build_conflicts() returns.
Fixes cxx1.sh, cxx2.sh, and cxx3.sh on Fedora 28 (which uses
binutils-2.29).

Avoids rtld segfault when _dl_lookup_symbol_x is called with NULL
for skip_map on a protected symbol relocation.
Global protected symbols may not actually require a copy relocaton,
in which case skip_map is undefined, so use the undef_map to determine
the symbol arch.

According to struct elf32_hd, the e_shnum is section header number, and the
index is e_shstrndx, not e_shnum.
This can fix segmention fault when handle libqb.so.0.18.2 from libqb_1.0.3.
It fails to handle libqb.so.0.18.2 and get errors:
Symbol section index outside of section numbers
Then segmentation fault, this is because the e_shnum is 34, while e_shstrndx is
27 (it would be 33 when no errors), I've checked several elf files to confirm
that the ones after e_shstrndx is NULL, so use e_shstrndx should be correct.

The layout1 test case currently fails for x32 because there is
insufficient address space for all the libraries.
There's two ways to fix this:
1. Increase mmap_end such that there's more space.
2. Reduce max_page_size so that less space is wasted.
I'm not sure what the implications of option 2 would be, so the attached
patch implements option 1.
This still limits the number of possible libraries somewhat severely,
but it's more than enough to pass the layout1 test.

The ifunc1, ifunc2, and ifunc3 tests currently fail on x86_64 x32 ABI
because the testcase crashes at runtime. The testcases run fine when not
prelinked.
In the case of ifunc1, the test tries to call the "lib2t2" function
directly, instead of using it as an indirect call, which leads to the
testcase aborting. In real code this would not cause an immediate crash,
but presumably would lead to undefined behaviour.
The attached patch fixes the problem by converting R_X86_64_32 conflict
relocations to R_X86_64_IRELATIVE (in the same way as R_X86_64_64
relocations are).
I've tested this with the cross_prelink branch and a suitably configured
cross-toolchain. I expect it would be fine on the master branch also,
but I can't test that.

prelink-rtld may report an "error while loading shared libraries" for
the wrong library.
If some set of DT_NEEDED DSOs are not in the default search path, they
may have a dso_list entry added, but no matching entry is added to the
needed_list. This causes the linker to miscalculate the max number of
dsos during build_local_scope(), which later causes find_needed() to not
search the entire l_local_scope[0]->r_list during
_dl_check_map_versions() (since the max from build_local_scope() becomes
l_local_scope[0]->r_nlist).
Since find_needed() searches through the r_list, which would have the
dso_list entries for the libraries that weren't found earlier, this cuts
the search short, meaning libraries near the end of the local scope don't
get included in the map version search.
As the comment in _dl_check_map_versions() suggests, if needed is NULL,
that means a dependency was not found and no stub entry created, which
should never happen.

Some linkers create a binary which has a section header table that is
not in section header offset order. However, as noted in check_dso(),
several routines in prelink and in libelf-0.7.0 too rely on sh_offsets
monotonically increasing, and if that fails then prelink quits. But
the check is only on dso's, not binaries. For binaries, fdopen_dso()
reorders the section headers to section header offset order prior to
work on the section data, so that the new prelinked binary is written
in section order.
However, on subsequent prelinks of a prelinked binary, the
prelink_exec() works on the undone section, not the fdopen_dso()
reordered sections, and may construct a section header table with
section orders different than the first prelink of the binary.
The function below tests for that case and resets the section header
order to the offset order by enforcing the binutils linker change:
'The net effect is .shstrab section is now placed after .symtab and
.strtab sections'. See binutils-gdb.git commit 3e19fb8f990e4c.

This provides name of dependent library which is missing like below:
./prelink: /test_binary: Could not find one of the dependencies:
./prelink-rtld: error while loading shared libraries: libB.so: cannot open shared object file: No such file or directory

* src/rtld/dl-version.c: Add debug for mising ld-linux or libc
During cross prelink if we miss out ld-linux.so.* or libc.so.* It prints below info:
./prelink: /test_binary: Could not parse `prelink-rtld: dl-version.c:219: rtld_check_map_versions:
Assertion `needed != ((void *)0)' failed.'
And thus we miss actual cause for this failure, by this patch we will know failure reason.
./prelink: /test_binary: Could not parse `./prelink-rtld: error while loading shared libraries: ld-linux.so.3'
(In this case ld-linux.so.3 was missing)

* Based on submission by Maninder Singh <maninder1.s@samsung.com>
src/get.c: Remove extra check for ld-linux.so.3 in strcmp
(remove first entry, second is already in upstream code)
The original submission removed the second entry, maintaining the first.
I choose to remove the first entry, and maintain the second as that more
closely matches the upstream prelink project and helps remove a minor
difference.
