DT_TEXTREL vs IFUNC

If you should somehow link non-pic objects into a PIE or shared
library, resulting in an object with DT_TEXTREL (text relocations)
set, and your executable or shared library also contains GNU indirect
functions, then you're in trouble.  To apply dynamic relocations
ld.so will make the text segment writable.  On most systems this will
make the text segment non-executable, which will then result in a
segfault when ld.so tries to run ifunc resolvers when applying
relocations against ifuncs.

This patch teaches PowerPC ld to detect the situation, and warn.

7 years agoBig-endian targets: Don't ignore offset into DW_OP_stack_value
Andreas Arnez [Thu, 16 Mar 2017 18:50:24 +0000 (19:50 +0100)]
Big-endian targets: Don't ignore offset into DW_OP_stack_value

Recently I fixed a bug that caused a DW_OP_implicit_pointer with non-zero
offset into a DW_OP_implicit_value to be handled incorrectly on big-endian
targets.  GDB ignored the offset and copied the wrong bytes:

  https://sourceware.org/ml/gdb-patches/2017-01/msg00251.html

But there is still a similar issue when a DW_OP_implicit_pointer points
into a DW_OP_stack_value instead; and again, the offset is ignored.  There
is an important difference, though: While implicit values are treated like
blocks of data and anchored at the lowest-addressed byte, stack values
traditionally contain integer numbers and are anchored at the *least
significant* byte.  Also, stack values do not come in varying sizes, but
are cut down appropriately when used.  Thus, on big-endian targets the
scenario looks like this (higher addresses shown right):

  |<- - - - - Stack value - - - - - - ->|
                  |                     |
                  |<- original object ->|
                  |
                  | offset ->|####|
      ^^^^
                              de-referenced
      implicit pointer

(Note how the original object's size influences the position of the
de-referenced implicit pointer within the stack value.  This is not the
case for little-endian targets, where the original object starts at offset
zero within the stack value.)

This patch implements the logic indicated in the above diagram and adds an
appropriate test case.  A new function dwarf2_fetch_die_type_sect_off is
added; it is used for retrieving the original object's type, so its size
can be determined.  That type is passed to dwarf2_evaluate_loc_desc_full
via a new parameter.

gas/arc: Limit special handling of t/nt flag to ARCv2

ARC700 extension (NPS400) which does not require this same special

In this commit I have restricted the special flag handling to only apply
if we are assembling for ARCv2.  This is a restructuring commit, and

Andreas Arnez [Tue, 14 Mar 2017 18:20:46 +0000 (19:20 +0100)]
inf-ptrace: Do not stop memory transfers after a single word

When inf_ptrace_xfer_partial performs a memory transfer via ptrace with
PT_READ_I, PT_WRITE_I (aka PTRACE_PEEKTEXT, PTRACE_POKETEXT), etc., then
it currently transfers at most one word.  This behavior yields degraded
performance, particularly if the caller has significant preparation work
for each invocation.  And indeed it has for writing, in
memory_xfer_partial in target.c, where all of the remaining data to be
transferred is copied to a temporary buffer each time, for breakpoint
shadow handling.  Thus large writes have quadratic runtime and can take
hours.

Note: On GNU/Linux targets GDB usually does not use
inf_ptrace_xfer_partial for large memory transfers, but attempts a single
read/write from/to /proc/<pid>/mem instead.  However, the kernel may
reject writes to /proc/<pid>/mem (such as kernels prior to 2.6.39), or
/proc may not be mounted.  In both cases GDB falls back to the ptrace
mechanism.

This patch fixes the performance issue by attempting to fulfill the whole
transfer request in inf_ptrace_xfer_partial, using a loop around the
ptrace call.

testsuite: Disable backslash_in_multi_line_command_test for old DejaGnus

I noticed that backslash_in_multi_line_command_test in
gdb.base/commands.exp failed on our RHEL6 servers.  I traced it to the
old version of DejaGnu (1.4.4).  I have found that instead of receiving
the expected:

  "print \\\nargc\n"

gdb received:

  "print  argc\n"

thus breaking the test and its purpose.  Versionof DejaGnu < 1.5 mess
up sending "\\\n", it somehow gets replaced with a space.  I found that
the following commit in DejaGnu fixed the issue:

http://git.savannah.gnu.org/cgit/dejagnu.git/commit/lib/remote.exp?id=3f39294f5cd6802858838d3bcc0ccce847ae17f2

Even though the commit is almost 10 years old, the following release of
DejaGnu was only in 2013, which is why we still have systems with the
old code.

If the DejaGnu version is < 1.5, we just skip the test.

gdb/testsuite/ChangeLog:

* gdb.base/commands.exp (backslash_in_multi_line_command_test):
Skip for versions of DejaGnu < 1.5.

testsuite: Introduce dejagnu_version

The next patch will require checking the DejaGnu version.  There is
already a test that does this,
gdb.threads/attach-many-short-lived-threads.exp.  This patch introduces
a new procedure, dejagnu_version, and makes that test use it.

The version number is "right-padded" with zeroes, to make sure that we
always return a triplet (major, minor, patch).

The procedure does not consider the DejaGnu versions from git.  For
example, if you used DejaGnu from its current master branch, the version
would be "1.6.1-git", meaning that 1.6.1 will be the next release.  I
figured we'll cross that bridge when (and if) we get there.

gdb/testsuite/ChangeLog:

* lib/gdb.exp (dejagnu_version): New proc.
* gdb.threads/attach-many-short-lived-threads.exp (bad_dejagnu):

7 years agold: Track changes to default region LMA even for empty sections

ld: Track changes to default region LMA even for empty sections

Given a linker script fragment like this:

   SECTIONS {
     . = 0x1000;
     .text   : AT(0x100) { *(.text)   }
     .data   : AT(0x200) { *(.data)   }
     .rodata : AT(0x300) { *(.rodata) }
   }

and an input file containing sections, '.text', '.data.1', and
'.rodata', then we'd expect the linker to place '.text' and '.rodata' in
the obvious way, and the '.data.1' orphan section would be located after
the '.data' section (assuming similar section properties).

Further, I believe that the expectation would be that the LMA for the
orphan '.data.1' section would start from 0x200 (as there is no '.data'
content).

However, right now, the LMA for '.data.1' would be 0x101, following on
from the '.text' section, this is because the change in LMA for the
'.data' section is not noticed by the linker, if there's no content in
the '.data' section.

What can be even more confusing to a user (though the cause is obvious
once you understand what's going on) is that adding some content to
'.data' will cause the orphan '.data.1' to switch to an LMA based off of
0x200.

This commit changes the behaviour so that an empty section that is in
the default lma region, and sets its lma, will adjust the lma of the
default region, this change will then be reflected in following sections
within the default lma memory region.

There's a new test to cover this issue that passes on a range of
targets, however, some targets generate additional sections, or have
stricter memory region size requirements that make it harder to come

7 years agold: better handling of lma region for orphan sections
Andrew Burgess [Tue, 17 Jan 2017 19:12:54 +0000 (19:12 +0000)]
ld: better handling of lma region for orphan sections

When picking an lma_region for an orphan section we currently create a
new lang_output_section_statement_type and then populate this with the
orphan section.

The problem is that the lang_output_section_statement_type has a prev
pointer that links back to the previous output section.  For non-orphan
output sections, that are created in linker script order, the prev
pointer will point to the output section that appears previous in linker
script order, as you'd probably expect.

The problem is that orphan sections are placed after processing the
linker script, and so, in the case of an output section created for an
orphan input section, the prev pointer actually points to the last
output section created.

This causes some unexpected behaviour when the orphan section is not
placed after the last non-orphan section that was created.

For example, consider this linker script:

  MEMORY {
    TEXT   : ORIGIN = 0x200,  LENGTH = 0x10
    RODATA : ORIGIN = 0x400,  LENGTH = 0x10
  }

  SECTIONS {
    .text   :           {*(.text)    } AT>TEXT
    .data   : AT(0x300) { *(.data)   }
    .rodata :           { *(.rodata) } AT>RODATA
  }

If we are processing an orphan section '.data.1' and decide to place
this after '.data', then the output section created will have a prev
pointer that references the '.rodata' output section.  The result of
this is that '.data.1' will actually be assigned to the RODATA lma
region, which is probably not the expected behaviour.

The reason why '.data.1' is placed into the lma region of the '.rodata'
section is that lma region propagation is done at the time we create the
output section, based on the previous output section pointer, which is
really just a last-output-section-created pointer at that point in time,
though the prev point is fixed up later to reflect the true order of the
output sections.

The solution I propose in this commit is to move the propagation of lma
regions into a separate pass of the linker, rather than performing this
as part of the enter/exit of output sections during linker script
parsing.

During this later phase we have all of the output sections to hand, and
the prev/next points have been fixed up by this point to reflect the
actual placement ordering.

There's a new test to cover this issue that passes on a range of
targets, however, some targets generate additional sections, or have
stricter memory region size requirements that make it harder to come
up with a generic pass pattern, that still tests the required
features.  For now I've set the test to ignore these targets.
