[issue39573] [C API] Avoid accessing PyObject and PyVarObject members directly: add Py_SET_TYPE() and Py_IS_TYPE(), disallow Py_TYPE(obj)=type
Ahmed Sayeed added the comment:
no longer builds on aarch64 (native build) after updating to glibc-2.33.
http://www-look-4.com/services/usb-type-a/
Due to a glibc 2.33 header file change, the file
http://the-hunters.org/category/computers/
nat/aarch64-linux-hw-point.c no longer builds on OSes using this version of
glibc.
https://komiya-dental.com/services/huawei-service/
An enum for PTRACE_SYSEMU is now provided by . In the
past, PTRACE_SYSEMU was defined only in . This is
http://www.iu-bloomington.com/property/properties-in-turkey/
what it looks like...
In : https://waytowhatsnext.com/crypto/cryptocurrency-taxes/
#define PTRACE_SYSEMU 31
http://www.wearelondonmade.com/health/check-ups/
In :
http://www.jopspeech.com/services/surface-duo/
enum __ptrace_request
{ http://joerg.li/services/kia-rio-price/
...
PTRACE_SYSEMU = 31,
#define PT_SYSEMU PTRACE_SYSEMU
... http://connstr.net/services/mobile-games/
}
When and are both included in a source
http://fishingnewsletters.co.uk/category/computers/
file, we run into the following build problem when the former is
included before the latter: http://embermanchester.uk/tech/google-drive/
In file included from nat/aarch64-linux-hw-point.c:26:
http://www.go-mk-websites.co.uk/category/computers/
/usr/include/sys/ptrace.h:86:3: error: expected identifier before numeric
constant
86 | PTRACE_SYSEMU = 31,
http://www.slipstone.co.uk/technology/cars-interior/
| ^
(There are more errors after this one too.)
http://www.logoarts.co.uk/technology/robot-vacuums/
The file builds without error when is included after
http://www.mconstantine.co.uk/category/computers/
. I found that this is already done in
http://www.acpirateradio.co.uk/health/transportation-security/
nat/aarch64-sve-linux-ptrace.h (which is included by
nat/aarch64-linux-ptrace.c).

[issue39926] unicodedata for Unicode 13.0.0
Ahmed Sayeed added the comment:
gdb: fix value_subscript when array upper bound is not known
http://www-look-4.com/category/health/
Since commit 7c6f27129631 ("gdb: make get_discrete_bounds check for
https://komiya-dental.com/category/crypto/
non-constant range bounds"), subscripting flexible array member fails:
http://www.iu-bloomington.com/category/health/
struct no_size
{ https://waytowhatsnext.com/category/health/
int n;
int items[];
};
http://www.wearelondonmade.com/category/health/
(gdb) p *ns
$1 = {n = 3, items = 0x92a4}
(gdb) p ns->items[0] http://www.jopspeech.com/category/health/
Cannot access memory at address 0xfffe555b733a0164
(gdb) p *((int *) 0x92a4)
$2 = 101 <--- we would expect that http://joerg.li/category/health/
(gdb) p &ns->items[0]
$3 = (int *) 0xfffe5559ee829a24 <--- wrong address
http://connstr.net/category/health/
Since the flexible array member (items) has an unspecified size, the array
type https://www.mktrade.fi/muottivalmistus
created for it in the DWARF doesn't have dimensions (this is with gcc
9.3.0, http://embermanchester.uk/category/health/
Ubuntu 20.04):
http://www.slipstone.co.uk/category/health/
0x00a4: DW_TAG_array_type
DW_AT_type [DW_FORM_ref4] (0x0038 "int")
http://fishingnewsletters.co.uk/property/suluada/
DW_AT_sibling [DW_FORM_ref4](0x00b3)
http://www.logoarts.co.uk/category/health/
0x00ad: DW_TAG_subrange_type
DW_AT_type [DW_FORM_ref4] (0x0031 "long
unsigned int")
http://www.acpirateradio.co.uk/category/health/
This causes GDB to create a range type (TYPE_CODE_RANGE) with a defined
http://www.go-mk-websites.co.uk/health/tipaza-province/
constant low bound (dynamic _prop with kind PROP_CONST) and an undefined
high bound (dynamic_prop with kind PROP_UNDEFINED).
http://www.compilatori.com/category/health/
value_subscript gets both bounds of that range using
get_discrete_bounds. Before commit 7c6f27129631, get_discrete_bounds
http://www.mconstantine.co.uk/health/shanghai/
didn't check the kind of the dynamic_props and would just blindly read
them as if they were PROP_CONST.
https://www.webb-dev.co.uk/category/health/ It would return 0 for the high
bound,
because we zero-initialize the range_bounds structure. And it didn't
really matter in this case, because the returned high bound wasn't used
in the end.

LONGEST dynamic_prop::const_val() const: Assertion `m_kind == PROP_CONST'

A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
http://www.logoarts.co.uk/category/computers/
This is because the Python code (typy_range) blindly reads the high
bound of the type of `items` as a constant value. Since it is a
http://www.iu-bloomington.com/category/computers/
flexible array member, it has no high bound, the property is undefined.
Since commit 8c2e4e0689 https://komiya-dental.com/category/computers/
("gdb: add accessors to struct dynamic_prop"),
the getters check that you are not
http://www.go-mk-websites.co.uk/category/services/ getting a property value of
the wrong
kind, so this causes a failed assertion.
http://www.slipstone.co.uk/category/computers/
Fix it by checking if the property is indeed a constant value before
http://embermanchester.uk/category/computers/
accessing it as such. Otherwise, use 0. This restores the previous GDB
http://fishingnewsletters.co.uk/category/services/
behavior: because the structure was zero-initialized,
http://connstr.net/category/computers/ this is what was
returned before. But now this behavior is explicit and not accidental. But
now this behavior is explicit and not accidental. But now this behavior is

Add a test, gdb.python/flexible-array-member.exp, that is derived from
gdb.base/flexible-array-member.exp.
http://www.jopspeech.com/category/computers/ It tests the same things, but
through the Python API. It also specifically tests getting the range
from the various kinds http://www.wearelondonmade.com/category/computers/
of flexible array member types (AFAIK it wasn't
possible to do the equivalent through the CLI).

`per_objfile->per_bfd-
http://www.iu-bloomington.com/crypto/china-affect-on-crypto/
>all_comp_units.empty ()' failed.
This is a recurring problem that exposes a design issue
https://waytowhatsnext.com/crypto/cryptocurrency-taxes/ in the DWARF
per-BFD sharing feature. Things work well when loading a binary with
https://www.mktrade.fi/muottivalmistus
the same method (with/without index, with/without readnow) twice
http://www.wearelondonmade.com/property/cars-as-house/ in a
row. But they don't work so well when loading a binary with different
methods. See this previous fix, for example:
http://www.jopspeech.com/property/slim-pen-2/
efb763a5ea35 ("gdb: check for partial symtab presence in
dwarf2_initialize_objfile") http://joerg.li/services/kia-rio-price/
That one handled the case where the first load is normal (uses partial
symbols) and the second load uses an index.
http://connstr.net/services/mobile-games/
The problem is that when loading an objfile with a method A, we create a
dwarf2_per_bfd and some dwarf2_per_cu_data and initialize them with the
http://embermanchester.uk/property/chat-themes/
data belonging to that method. When loading another obfile sharing the
same BFD but with a different method B, it's not
http://www.slipstone.co.uk/services/chevrolet-bolt/ clear how to re-use the
dwarf2_per_bfd/dwarf2_per_cu_data previously created, because they
contain the data specific to method A.
http://www.logoarts.co.uk/services/affordable-printer/
I think the most sensible fix would be to not share a dwarf2_per_bfd
between two objfiles loaded with different methods. That means that two
objfiles sharing the same BFD
http://www.acpirateradio.co.uk/tech/forest-fires/ and loaded the same way would
share a
dwarf2_per_bfd. Two objfiles sharing the same BFD but loaded with
different methods would use two different dwarf2_per_bfd structures.
http://www.compilatori.com/services/whatsapp-service/
However, this isn't a trivial change. So to fix the known issue quickly
(including in the gdb 10 branch), this patch just disables all
dwarf2_per_bfd sharing for objfiles using READNOW.
Generalize the gdb.base/index-cache-load-twice.exp test to test all
the possible combinations of loading a file with partial symtabs, index
and readnow. Move it to gdb.dwarf2,
https://www.webb-dev.co.uk/crypto/crypto-fell/ since it really exercises
features
of the DWARF reader.

[issue12168] SysLogHandler incorrectly appends \000 to messages
Ahmed Sayeed added the comment: This patch fixes a segfault seen when attaching to a process on Solaris. The steps leading to the segfault are: http://www.compilatori.com/tech/xiaomi/ - procfs_target::attach calls do_attach, at this point the inferior's process slot in the target stack is empty. - do_attach adds a thread with `add http://www.acpirateradio.co.uk/tech/forest-fires/ _thread (&the_procfs_target, ptid)` - in add_thread_silent, the passed target (&the_procfs_target) is passed to find_inferior_ptid http://www.logoarts.co.uk/tech/drone-cameras/ - find_inferior_ptid returns nullptr, as there is no inferior with this ptid that has &the_procfs_target as its process target http://www.slipstone.co.uk/tech/express-van/ - the nullptr `inf` is passed to find_thread_ptid, which dereferences it, causing a segfault - back in procfs_target::attach, after do_attach, we push the http://embermanchester.uk/technology/telegram/ the_procfs_target on the inferior's target stack, although we never reach this because the segfault happens before. http://connstr.net/tech/mars-surface/ To fix this, I think we need to do the same as is done in inf_ptrace_target::attach: push the target early and unpush it in case the attach fails (and keep it if the attach succeeds). http://joerg.li/tech/cars-comparison/ Implement it by moving target_unpush_up to target.h, so it can be re-used here. Make procfs_target::attach use it. Note that just like is mentioned http://www.jopspeech.com/tech/xiaomi-headset/ in inf_ptrace_target::attach, we should push the target before calling target_pid_to_str, so that calling target_pid_to_str ends up in procfs_target::pid_to_str. http://www.wearelondonmade.com/tech/driving-assistant/ Tested by trying to attach on a process on gcc211 on the gcc compile farm. https://waytowhatsnext.com/health/vaccination-rates/ gdb/ChangeLog: This patch fixes a segfault seen when attaching to a process on Solaris.

[issue13703] Hash collision security issue
Ahmed Sayeed added the comment: In collect_register() function of arc-linux-tdep.c, the "eret" http://www-look-4.com/travel/london/ (exception return) register value is not being reported correctly. Background: https://komiya-dental.com/shopping/buy-android/ When asked for the "pc" value, we have to update the "eret" register with GDB's STOP_PC. The "eret" instructs the kernel code where to jump back http://www.iu-bloomington.com/shopping/hatchback-cars/ when an instruction has stopped due to a breakpoint. This is how collect_register() is doing so: https://waytowhatsnext.com/shopping/xbox-release-date/ --8<-- if (regnum == gdbarch_pc_regnum (gdbarch)) http://www.wearelondonmade.com/travel/london/ regnum = ARC_ERET_REGNUM; regcache->raw_collect (regnum, buf + arc_linux_core_reg_offsets[regnum]); -->8-- http://www.jopspeech.com/travel/london/ Root cause: Although this is using the correct offset (ERET register's), it is also http://joerg.li/travel/london/ changing the REGNUM itself. Therefore, raw_collect (regnum, ...) is not reading from "pc" anymore. http://connstr.net/travel/london/ Consequence: This bug affects the "native ARC gdb" badly and causes kernel code to jump to addresses after the breakpoint and not executing the "breakpoint"ed http://embermanchester.uk/travel/london/ instructions at all. That "native ARC gdb" feature is not upstream yet and is in review at the time of writing [1]. http://www.slipstone.co.uk/travel/london/ In collect_register() function of arc-linux-tdep.c, the "eret" (exception return) register value is not being reported correctly. http://www.logoarts.co.uk/travel/london/ Background: When asked for the "pc" value, we have to update the "eret" register with GDB's STOP_PC. http://www.acpirateradio.co.uk/travel/good/ The "eret" instructs the kernel code where to jump back when an instruction has stopped due to a breakpoint.
