[PATCH v5 01/12] Zero-initialize linux note sections

[Pedro Franco de Carvalho]

This patches changes linux-tdep.c so that the buffer used to write
note sections when generating a core file is zero-initialized. This
way, bytes that are not collected won't contain random
data (e.g. padding bytes).

gdb/ChangeLog:
YYYY-MM-DD Pedro Franco de Carvalho <***@linux.ibm.com>

* linux-tdep.c (linux_collect_regset_section_cb): Use
std::vector<gdb_byte> instead of char * and malloc for buf.
Remove xfree.

This patch removes rs6000_pseudo_register_reggroup_p.

Group membership for the pseudoregisters can be detected through their
types in default_register_reggroup_p through
tdesc_register_reggroup_p.

Now that linux-tdep.c already zero-initializes the buffer used for
generating core file notes, there is no need to do this in the linux
collect functions for the vector regset. The memsets in gdbserver were

From: Edjunior Barbosa Machado <***@linux.vnet.ibm.com>

This patch adds support for registers of the Event Based Branching and
Performance Monitoring Units for the powerpc linux native and core
file targets, and for the powerpc linux server stub.

All three EBB registers are accessible. Only a subset of the PMU
registers can be accessed through ptrace. Because of this, the PMU
registers are enumerated individually in gdbarch_tdep, as opposed to
having a single "have_pmu" flag. This is intended to make it easier
to add additional PMU registers in the future, since checking a
"have_pmu" flag elsewhere in the code would no longer be correct. The
tdesc feature is named org.gnu.gdb.power.linux.pmu because of this.

It's unclear if it makes sense to save and restore these registers
across function calls, since some of them can be modified
asynchronously. They are also not tracked in record-replay mode.

The kernel can return ENODATA when ptrace is used to get the EBB
registers, unless a linux performance event that uses EBB is open in
the inferior. For this reason, the "fill" functions in the server
stub for the ebb register sets is not implemented.

Since gdbserver writes all registers in one go before resuming the
inferior, this error would not be detected at the time the user tries
to write to one of the registers on the client side, and gdbserver
would print out warnings every time it resumes the inferior when no
ebb performance event is opened, so there is currently no
straightforward way to handle this case. This means the ebb registers
in the client-side regcache can become dirty when the user tries to
write to them, until the inferior is resumed and stopped again.

A related issue is that 'G' packets used to write to unrelated
registers will include bad data for the EBB registers if they are
unavailable, since no register status information is included in the
'G' packet. This data won't be written to the inferior by the
gdbserver stub because the "fill" functions are not implemented, and
currently the gdbserver stub doesn't change the status of the
registers in its own regcache in response to 'G' packets.

Another limitation for the ebb registers is that traceframes don't
record if registers are available or not, so if these registers are
collected when a tracepoint is hit and the inferior has no ebb event
opened, the user will see zero values for all of them, instead of the
usual <unavailable>.

Because these registers are often unavailable, trying to store them
with target_store_registers with -1 for the regno argument (all
registers) would almost always fail, so they are ignored in this case.

Currently rs6000_gdbarch_init will accept a tdesc with the
"org.gnu.gdb.power.vsx" feature but without the
"org.gnu.gdb.power.altivec" or "org.gnu.gdb.power.fpu".

It isn't clear from the standard features documentation that these are
requirements. However, these tdescs would cause trouble in the VSX
pseudo-register functions, so this patch will cause them to be
rejected.

gdb/ChangeLog:
YYYY-MM-DD Pedro Franco de Carvalho <***@linux.ibm.com>

* rs6000-tdep.c (rs6000_gdbarch_init): Reject tdescs with vsx but
without altivec or fpu.

Yes, I can update the documentation to make this a requiremnt. Can I do
it in a separate patch?

Thanks!

Thanks, Eli!

[Pedro Franco de Carvalho]

From: Edjunior Barbosa Machado <***@linux.vnet.ibm.com>

This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.

These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.

The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for other registers with other info (e.g., nip is filled with
the contents of TFHAR). GDB doesn't handle these other registers.
This means that core files generated by GDB will show values of zero
for these registers, while core files generated by the kernel will
have other values. Core files generated by the kernel have a note
section for checkpointed GPRs with the same size for both 32-bit and
64-bit threads, and the values for the registers of a 32-bit thread
are squeezed in the first half, with no useful data in the second
half. GDB generates a smaller note section for 32-bit threads, but
can read both sizes.

The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.

Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.

The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.

Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.

Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.

The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.

Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.

The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.

Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

This is V5 of: https://sourceware.org/ml/gdb-patches/2018-08/msg00381.html

AFAICT, this mainly refreshes the patch set, and applies some polish,
but doesn't address the previously discussed issues, right?

TBC, I don't want to block this at all, I think it's looking good.
Just want to understand if there's a plan, and if so, what is it.

I.e., what is the conclusion wrt to the differences in one of the note
sections generated by the kernel for a core file and the one generated
by GDB? Was that resolved? Will it be?

As for the EBB/PMU patch, about gdbserver writing all registers in one go
before resuming the inferior, and the error would not being detected at the
time the user tries to write them, did you try making gdbserver flush
the regcache after handling 'G' and 'P' packets? From the previous
discussion, it sounded like that would work?

* Explained further limitations of unavailable registers with respect
to 'G' packets in the commit message of "[PowerPC] Add support for
EBB and PMU registers".
* Changed linux_collect_regset_section_cb to use std::vector<gdb_byte>
instead of std::vector<char> in the first patch ("Zero-initialize
linux note sections").
* Defined ppc_linux_collect_core_cpgrregset in ppc-linux-tdep.c and
changed ppc_linux_iterate_over_regset_sections to call it when
generating core files, in order to fill in the checkpointed NIP and
MSR slots in the core file with reasonable values (TFHAR and the
regular MSR), in "[PowerPC] Add support for HTM registers".
* Removed ppc_linux_regset_available_p, removed call to store_regset
with regsets that can be unavailable when store_registers is called
with -1, added comment explaining why.
* Changed fetch_regset/store_regset in ppc-linux-nat.c to call the
supply/collect function pointers from the regset instead of
regcache_supply/collect_regset.
* Reordered some of the regmap/regset definitions in ppc-linux-tdep.c
for consistency with the existing definitions.
* Added various comments for global variables, functions and to the
new test cases.

I.e., what is the conclusion wrt to the differences in one of the note
sections generated by the kernel for a core file and the one generated
by GDB? Was that resolved? Will it be?

Sorry, I really should have explained this better in the cover letter,
and I forgot to update the commit message explaining the solution we
picked for this issue.

I discussed this with Ulrich and we came to the conclusion that it would
be simpler to fill in the data for two of the registers that were
different in the core file using other registers that are available to
GDB, since they are not particularly useful as separate user-visible
registers. This still leaves out some additional registers in this
regset that GDB isn't aware of, which are most of the time 0. I will
explain this in more detail below, but in this patch this is implemented
with a different collect function used
(ppc_linux_collect_core_cpgrregset) used by
ppc_linux_iterate_over_regset_sections.

To give you some background, the checkpointed registers are the values
that are used to restore some of the regular registers to
pre-transactional values in case a hardware transaction fails. This
includes the GPRs, FPRs, vector registers and others.

The kernel uses a pt_regs struct to hold the regular GPRs and various
others registers. It also uses this struct to represent the equivalent
checkpointed registers, and to generate the note section, except that
only a subset of the registers in pt_regs is actually checkpointed by
the processor. All of the registers that are actually checkpointed are
visible to the GDB user and are correctly filled in the note section
generated by GDB.

This leaves out various other registers from pt_regs. One of these is
the NIP (the pc), which the kernel fills in with the value of another
register, TFHAR. Since TFHAR is in fact visible to GDB, GDB uses its
value to fill in the corresponding slot in the core file. The
"checkpointed" MSR (processor status register), is used by the kernel
for some internal state tracking. We use the regular MSR to fill in the
corresponding slot. These usually differ in some bits, and in certain
conditions the checkpointed MSR from the kernel can be zero.

The remaining registers in the checkpointed pt_regs are not filled in by
the kernel and don't represent anything. They will only have non-zero
values in a kernel-generated core file if someone explicitly sets them
with ptrace before the process crashes.

As for the EBB/PMU patch, about gdbserver writing all registers in one go
before resuming the inferior, and the error would not being detected at the
time the user tries to write them, did you try making gdbserver flush
the regcache after handling 'G' and 'P' packets? From the previous
discussion, it sounded like that would work?

I haven't tried this yet. I did think about this more and although it
might work using 'P' packets, I'm not sure how to go about handling
unavailable registers in general with the 'G' packet. The problem is
that the server would need to somehow only flush these registers in
response to 'P' packets, and ignore them when they come from 'G'
packets.

This is becasue if the client always uses 'G' packets to store any
registers, including the ones that are always available, and the server
flushes the regcache to detect errors, most 'G' packets would return in
error because the inferior is usually not in a state in which the
unavailable registers can be written.

It's not clear that the 'xxxxx' encoding for unavailable registers can
be used in 'G' packets, like it is for 'g' packets. The gdbserver stub
doesn't handle this and assumes the 'G' packet contents will be properly
encoded register values, it only uses this encoding when replying to 'g'
packets.

Maybe a solution is to prevent writing to these registers on the client
side if the target is remote and print a warning (possibly through
gdbarch_cannot_store_register).

Thanks!!

sections generated by the kernel for a core file and the one generated
by GDB? Was that resolved? Will it be?

As Pedro mentioned, I believe the implementation in this latest patch
set as as good as we're going to get, and should result in GDB core
files that are mostly equivalent to kernel core files (and in the
minor details where they're not, I'd argue those are kernel bugs that
should be fixed there).

time the user tries to write them, did you try making gdbserver flush
the regcache after handling 'G' and 'P' packets? From the previous
discussion, it sounded like that would work?

There's really two issues here. One is that optionally present, but writable,
registers aren't currently supported well in GDB in my opinion. The second
is that the current PowerPC kernel is really buggy with how it handles the
EBB register set in particular:
- First of all, there no reason at all why this regset should be optional
in the first place; it might as well just be always available.
- Even so, the test the kernel used to implement the availability check
is just broken, it uses the inverse of the test in PTRACE_SETREGSET vs.
PTRACE_GETSETRET.
Because of the latter, I think you'll never be able to complete the
read-modify-write cycle to write an EBB register via ptrace regsets
with a current kernel, and so it is effectively read-only anyway.

But even if we assume the EBB regset will be fixed, we still should
handle writable optional regsets better, since at least the HTM
checkpointed registers are really of this type. With those, there
are two problems:
- The user ought to be warned early with a reasonable message when
attempting to modify an unvailable register.
- The mere presence of unavailable registers should not cause spurious
errors when attempting to write *other* registers.

For the second part, this can happen in two places currently. One is
if the native target store_registers routine is called with regnum -1.
But this is actually done only from proc-service.c code which handles
only general-purpose register or floating-point registers. So it should
be fine to just ignore optional regsets in that case (as Pedro's current
patch set does). Maybe the documentation of that routine should make
this explicit ...

The other is gdbserver. As far as I can see, gdbserver currently does
not implement the 'p'/'P' packets at all, only 'g'/'G'. Therefore it
will always attempt to write all registers. The problem is that this
will show an error if any of those writes fail.

This is because, while there is code in regsets_fetch_inferior_registers
to ignore optional regsets when unavailable, there is no corresponding
code in regsets_store_inferior_registers. This may simply be because
all other optional regsets on existing targets so far have been read-
only ...

Pedro's current patches just effectively make the new optional regsets
read-only for gdbserver too. In my mind, this would be an acceptable
solution at least for now, which can hopefully be improved upon further.

Another simple solution would be to add code to ignore unavailable
regsets to regsets_store_inferior_registers as well. This will work,
but might silently ignore some situations that really could be problems.
To improve upon that, we might try to track whether there are any
registers in the regset to be written that are actually REG_VALID
(if the regset was really unvailable, all registers in it will in
fact be REG_UNAVAILABLE anyway), and skip the attempt to write it
just in that case.


But really, the user-visible error should not come from gdbserver
anyway IMO. This should really be handled by GDB up front. One
way might be to just always throw an error right in regcache::raw_write
when attempting to modify a REG_UNAVAILABLE register in the first
place. But that's a rather significant change, I'm not sure if that
might cause other problems on some platforms ...


In any case, I'd really like to get Pedro's patch set in as-is or
with just a simple fix (like the regsets_store_inferior_registers
change described above). The more sophisticated solution can
still be done later ...


Pedro, I've looked over the patch set again, and (apart from this
discussion here), everything looks good to me.

Thanks for the explanations. That's really all I wanted; we can
always fix things going forward, but it's important for the community
to have these issues written down in case someone in the future
runs into them before they are addressed and we get to debug them.

I'm fine with merging the patchset as is.

Thanks a lot! I've checked these in now.

Ah, I'm now seeing a regression on my Cell (RHEL5) build bot:

gdb/ppc-linux-nat.c: In function 'void fetch_regset(regcache*, int, int, int, const regset*)':
gdb/ppc-linux-nat.c:548:15: error: 'PTRACE_GETREGSET' was not declared in this scope

There is a fallback definition for this in nat/linux-ptrace.h,
but for some reason this is not actually used in ppc-linux-nat.c
(which uses nat/gdb_ptrace.h) instead. This probably needs to
be fixed.

Bye,
Ulrich

Sorry, didn't think about this possibility!

I've simply added the .h files in the patch below to both the native
and the server targets. The ptrace call will still be made to
determine the tdesc, but it should return in error and cause the new
features not to be selected (no exceptions are thrown by
check_regset).

Is this ok?

Subject: [PATCH] [PowerPC] Include nat/linux-ptrace.h in native targets

Patch "[PowerPC] Add support for PPR and DSCR" used
PTRACE_GETREGSET/SETREGSET without including the fallback definitions
from "nat/linux-ptrace.h". Include this header to avoid breaking
builds in older kernels that don't define them.

gdb/ChangeLog:
YYYY-MM-DD Pedro Franco de Carvalho <***@linux.vnet.ibm.com>

* ppc-linux-nat.c: Include nat/linux-ptrace.h.

gdb/gdbserver/ChangeLog:
YYYY-MM-DD Pedro Franco de Carvalho <***@linux.vnet.ibm.com>

* linux-ppc-low.c: Include nat/linux-ptrace.h.

This is OK.

This is probably unnecessary; linux-ppc-low.c already includes
linux-low.h which in turn includes nat/linux-ptrace.h

Ah I didn't notice that. However, the wiki says I shouldn't use
definitions by indirect inclusion, and linux-low.c itself includes both
headers. Should I still remove this?

Thanks!

Well, it doesn't really matter. If you want to add the include,
that's fine with me as well.
