Subject: [PATCH 01/28] Fix for "dev" command on Linux 5.11 and later
|
||||
|
||||
The following kernel commits eventually removed the bdev_map array in
|
||||
Linux v5.11 kernel:
|
||||
|
||||
e418de3abcda ("block: switch gendisk lookup to a simple xarray")
|
||||
22ae8ce8b892 ("block: simplify bdev/disk lookup in blkdev_get")
|
||||
|
||||
Without the patch, the "dev" command fails to dump block device data
|
||||
with the following error:
|
||||
|
||||
crash> dev
|
||||
...
|
||||
dev: blkdevs or all_bdevs: symbols do not exist
|
||||
|
||||
To get block device's gendisk, search blockdev_superblock.s_inodes
|
||||
instead of bdev_map.

Since the kernel commit 2d8ae638bb86 ("powerpc: Make the NR_CPUS max 8192")
|

the NR_CPUS on Linux kernel ranges from 1-8192. So let's match NR_CPUS with

the max NR_CPUS count on the Linux kernel.

Subject: [PATCH 02/28] Extend field length of task attributes
|
||||
|
||||
Nowadays, some machines have many CPU cores and memory, and some
|
||||
distributions have a larger kernel.pid_max parameter, e.g. 7 digits.
|
||||
This impairs the readability of a few commands, especially "ps" and
|
||||
"ps -l|-m" options.
|
||||
|
||||
Let's extend the field length of the task attributes, PID, CPU, VSZ,
|
||||
and RSS to improve the readability.

||||

||||

Only older kernel (v2.4) used h/w interrupt stack to store frames when

useless for later kernels. For the sake of backward compatibility keep

some bytes from being wasted.

ppc64_paca_init() function is specifically used to initialize percpu

misleading. Rename it to ppc64_paca_percpu_offset_init to reflect its

purpose.

Subject: [PATCH 06/28] ppc64: handle backtrace when CPU is in an emergency
|
||||
stack
|
||||
|
||||
A CPU could be in an emergency stack when it is running in real mode
|
||||
or any special scenario like TM bad thing. Also, there are dedicated
|
||||
emergency stacks for machine check and system reset interrupt. Right
|
||||
now, no backtrace is provided if a CPU is in any of these stacks.
|
||||
This change ensures backtrace is processed appropriately even when
|
||||
a CPU is in any one of these emergency stacks. Also, if stack info
|
||||
cannot be found, print that message always instead of only when
|
||||
verbose logs are enabled.

||||

||||

Subject: [PATCH 08/15] gdb: print details of unnamed struct and union
|
||||
|
||||
Currently gdb's "ptype" command does not print the details of unnamed
|
||||
structure and union deeper than second level in a structure, it prints
|
||||
only "{...}" instead. And crash's "struct" and similar commands also
|
||||
inherit this behavior, so we cannot get the full information of them.
|
||||
|
||||
To print the details of them, change the show variable when it is an
|
||||
unnamed one like crash-7.x.
|
||||
|
||||
Without the patch:
|
||||
crash> struct -o page
|
||||
struct page {
|
||||
[0] unsigned long flags;
|
||||
union {
|
||||
struct {...};
|
||||
struct {...};
|
||||
...
|
||||
|
||||
With the patch:
|
||||
crash> struct -o page
|
||||
struct page {
|
||||
[0] unsigned long flags;
|
||||
union {
|
||||
struct {

set VA_BITS_ACTUAL
|
||||
|
||||
Setting st->_stext_vmlinux to UNINITIALIZED to search for "_stext"
|
||||
from the vmlinux. In the scenario where kaslr is disabled and
|
||||
without vmcoreinfo, crash will get the wrong MODULES/VMALLOC ranges
|
||||
and cause a failure in parsing a raw RAM dumpfile.

|

"sum" command in coreutils-9.0 (e.g. Fedora 36) started to output a file

wrongly and re-applies it unnecessarily.

Use standard input to fix it and "md5sum" to improve detection.

Subject: [PATCH 16/28] arm64: use TCR_EL1_T1SZ to get the correct info if
|
||||
vabits_actual is missing
|
||||
|
||||
After kernel commit 0d9b1ffefabe ("arm64: mm: make vabits_actual a build
|
||||
time constant if possible"), the vabits_actual is not compiled to kernel
|
||||
symbols when "VA_BITS > 48" is false.
|
||||
|
||||
So the crash will not find the vabits_actual symbol, and it will fail
|
||||
in the end like this:
|
||||
|
||||
# ./crash
|
||||
...
|
||||
WARNING: VA_BITS: calculated: 46 vmcoreinfo: 48
|
||||
crash: invalid kernel virtual address: ffff88177ffff000 type: "pud page"
|
||||
|
||||
This patch introduces the arm64_set_va_bits_by_tcr(), and if crash cannot
|
||||
find vabits_actual symbol, it will use the TCR_EL1_T1SZ register to get
|
||||
the correct VA_BITS_ACTUAL/VA_BITS/VA_START.
|
||||
|
||||
Tested this patch with:
|
||||
1.) the live mode with /proc/kcore
|
||||
2.) the kdump file with /proc/vmcore.

Subject: [PATCH 17/28] Fix "task -R" by adding end identifier for union in
|
||||
task_struct
|
||||
|
||||
Previously, the start and end identifiers for union are " {\n" and
|
||||
" }, \n". However the end identifier is not always as expected.
|
||||
" },\n" can also be the end identifier with gdb-10.2. As a result,
|
||||
variable "randomized" is in incorrect state after union, and fails to
|
||||
identify the later struct members. For example, we can reproduce the
|
||||
issue as follows:
|
||||
|
||||
crash> task
|
||||
PID: 847 TASK: ffff94f8038f4000 CPU: 72 COMMAND: "khungtaskd"
|
||||
struct task_struct {
|
||||
thread_info = {
|
||||
flags = 2148024320,
|
||||
status = 0,
|
||||
preempt_lazy_count = 0
|
||||
},
|
||||

|
||||

|
||||

|
||||

|
||||

|
||||

Subject: [PATCH 18/28] Let gdb get kernel module symbols info from crash
|
||||
|
||||
Gdb will try to resolve an address to its corresponding symbol name such as
|
||||
when printing a structure. It works fine for kernel symbols, because gdb can
|
||||
find them through vmlinux. However as for kernel modules symbols, crash
|
||||
resolves them by dig into "struct module", which gdb don't know. As a result,
|
||||
gdb fails to translate a kernel module address to its symbol name without
|
||||
"mod -s|-S" options. For example we can reproduce the issue as follows.
|
||||
|
||||
crash> timer
|
||||
....
|
||||
4331308176 336 ffff94ea24240860 ffffffffc03762c0 <estimation_timer>
|
||||
....
|
||||
crash> sym 0xffffffffc03762c0
|
||||
ffffffffc03762c0 (t) estimation_timer [ip_vs]
|
||||
|
||||
Before patch:
|
||||
crash> timer_list ffff94ea24240860
|
||||
struct timer_list {
|
||||
....
|
||||
function = 0xffffffffc03762c0,
|
||||
....
|
||||
}
|
||||
|
||||
After patch:
|
||||
crash> timer_list ffff94ea24240860
|
||||
struct timer_list {
|
||||
....
|
||||
function = 0xffffffffc03762c0 <estimation_timer>,
|
||||
....
|
||||
}
|
||||
|
||||
In this patch, we add an interface for gdb, when gdb trying to build kernel
|
||||
module's address symbolic, the info can be get from crash.

|

commit 364b2e413c69 ("sbitmapq: remove struct and member validation
|

in sbitmapq_init()") allowed the use of the "sbitmapq" command

unconditionally. Without the patch, the command fails with the

Now the command supports Linux 4.9 and later kernels since it was

abstracted out, so it can be limited by the non-existence of the

sbitmap structure.

Subject: [PATCH 19/28] x86_64: Correct the identifier when locating the call
|
||||
instruction
|
||||
|
||||
The previous implementation to locate the call instruction is
|
||||
to strstr "call", then check whether the previous char is ' '
|
||||
or '\t'. The implementation is problematic. For example it
|
||||
cannot resolve the following disassembly string:
|
||||
|
||||
"0xffffffffc0995378 <nfs41_callback_svc+344>:\tcall 0xffffffff8ecfa4c0 <schedule>\n"
|
||||
|
||||
strstr will locate the "_call" and char check fails,
|
||||
as a result, extract_hex fails to get the calling address.
|
||||
|
||||
NOTE: the issue is more likely to be reproduced when patch[1] applied.
|
||||
Because without patch[1], the disassembly string will be as follows,
|
||||
so the issue is no longer reproducible.
|
||||
|
||||
"0xffffffffc0995378:\tcall 0xffffffff8ecfa4c0 <schedule>\n"
|
||||
|
||||
Before the patch:
|
||||
crash> bt 1472
|
||||
PID: 1472 TASK: ffff8c121fa72f70 CPU: 18 COMMAND: "nfsv4.1-svc"

|
||||
#1 [ffff8c16231a3e40] schedule at ffffffff8ecfa4e9
|
||||
|
||||
After the patch:
|
||||
crash> bt 1472
|
||||
PID: 1472 TASK: ffff8c121fa72f70 CPU: 18 COMMAND: "nfsv4.1-svc"

|
||||
#4 [ffff8c16231a3f50] ret_from_fork at ffffffff8ed07898
|
||||
|
||||
This patch fix the issue by strstr "\tcall" and " call", to
|
||||
locate the correct call instruction.

Subject: [PATCH 22/28] Fix for the invalid linux_banner pointer issue
|
||||
|
||||
Currently, crash may fail with the following error:
|
||||
|
||||
# ./crash -s vmlinux vmcore
|
||||
WARNING: invalid linux_banner pointer: 65762078756e694c
|
||||
crash: vmlinux and vmcore do not match!
|
||||
|
||||
The reason is that the type of the symbol in the data segment may be
|
||||
defined as 'D' or 'd'. The crash only handled the type 'D', but it
|
||||
didn't deal with the type 'd'. For example:
|
||||
|
||||
# nm vmlinux | grep linux_banner
|
||||
ffffffff827cfa80 d linux_banner
|
||||
|
||||
It has been observed that a vmlinux compiled by clang has this type.
|
||||
Let's add the type 'd' recognition to solve such issue.

Subject: [PATCH 23/28] Fix "kmem" failing to print task context when address
|

|
||||
|
||||
When kernel enabled CONFIG_VMAP_STACK, stack can be allocated to
|
||||
vmalloced area. Currently crash didn't handle the case, as a result,
|
||||
"kmem" will not print the task context as expected. This patch fix the
|

bug by checking if the address is a vmalloced stack first.

Subject: [PATCH 24/28] Fix page offset issue when converting physical to
|
||||
virtual address
|
||||
|
||||
When trying to convert a physical address to its virtual
|
||||
address in dump_vmap_area() and dump_vmlist(), the vi->retval
|
||||
is added by 2 values: the page aligned address "pcheck"
|
||||
and page offset address "PAGEOFFSET(paddr)".
|
||||
|
||||
However "paddr" is given by "pcheck", is also page aligned,
|
||||
so "PAGEOFFSET(paddr)" is always 0.
|
||||
|
||||
In this patch, we will use PAGEOFFSET(vi->spec_addr) to give the
|
||||
page offset, vi->spec_addr is the physical address we'd like
|
||||
to convert, which contains the correct page offset.

Subject: [PATCH 26/28] ppc64: still allow to move on if the emergency stacks
|
||||
info fails to initialize
|
||||
|
||||
Currently crash will fail and then exit, if the initialization of
|
||||
the emergency stacks information fails. In real customer environments,
|
||||
sometimes, a vmcore may be partially damaged, although such vmcores
|
||||
are rare. For example:
|
||||
|
||||
# ./crash ../3.10.0-1127.18.2.el7.ppc64le/vmcore ../3.10.0-1127.18.2.el7.ppc64le/vmlinux -s
|
||||
crash: invalid kernel virtual address: 38 type: "paca->emergency_sp"
|
||||
#
|
||||
|
||||
Lets try to keep loading vmcore if such issues happen, so call
|
||||
the readmem() with the RETURN_ON_ERROR instead of FAULT_ON_ERROR,
|
||||
which allows the crash move on.

Subject: [PATCH 27/28] Fix segmentation fault in
|
||||
page_flags_init_from_pageflag_names()
|
||||
|
||||
When read_string() fails in page_flags_init_from_pageflag_names(),
|
||||
error() dereferences the name variable to print the string that the
|
||||
variable points to. However, name points to a string that is not in
|
||||
crash's memory-space thus triggering a segmentation fault.
|
||||
|
||||
This patch replaces "%s" in the error message with "%lx" so the address
|
||||
is printed instead. Also replaces "%ld" for mask with "%lx".

||||

Subject: [PATCH 28/28] Fix for "ps/vm" commands to display correct %MEM and
|
||||
RSS values
|
||||
|
||||
The ps/vm commands may print the bogus value of the %MEM and RSS, the
|
||||
reason is that the counter of rss stat is updated in asynchronous manner
|
||||
and may become negative, when the SPLIT_RSS_COUNTING is enabled in kernel.
|
||||
|
||||
As a result, crash will read it from memory and convert from negative to
|
||||
unsigned long integer, eventually it overflows and gets a big integer. For
|
||||
example:
|
||||
|
||||
crash> ps 1393
|
||||
PID PPID CPU TASK ST %MEM VSZ RSS COMM
|
||||
1393 1 24 ffff9584bb542100 RU 541298032135.9 4132 18014398509481908 enlinuxpc64
|
||||
^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^
|
||||
|
||||
This is unexpected, crash needs to correct its value for this case.
