[PATCH] display ST when using ps -l
by qiaonuohan
Hello Dave,
I was recommended to add the display of ST when using ps -l. Because it
is simple, so I made the patch at first and then talk about the merit of
patch with you.
The display is like below:
crash> ps -l
[100126284069406] PID: 2389 TASK: ffff88047416aa80 ST:IN CPU: 12
COMMAND: "kondemand/12"
[100126285814043] PID: 795 TASK: ffff880470cb3540 ST:UN CPU: 0
COMMAND: "jbd2/sda2-8"
[100126284061076] PID: 2377 TASK: ffff88047426c100 ST:IN CPU: 0
COMMAND: "kondemand/0"
[100126284058337] PID: 70050 TASK: ffff88045beaeac0 ST:RU CPU: 3
COMMAND: "crash"
[100126285834369] PID: 70781 TASK: ffff88046929e100 ST:RU CPU: 0
COMMAND: "dd"
...
I think "ps -l", which displays task sorted by last_run/timestamp, is
concerning about the state of the task. Taking it into consideration, on
a live system with original code, we use "ps -l" to show the sorted
tasks at first, then use "ps" to display the state. The two pieces of
information in such situation are not consonant. This is the reason why
ST is needed.

Sial is a C interpreter with a few twists like the string type and its
associated operators .
The ps example is a good one. Using args and callbacks, including
printing recursively (parent->siblings) the process tree.
Let me know if you have questions. I tried to comment the example as
much as I could at the time. And yes, check out the readme files.
It also has a built in preprocessor which enables you to write/modify
debugging code that easily adapts to the linux version of the core you
are looking at.
All of the type and symbol information from kernel space is available in
sial through the dwarf interface.
You can combine these 2 features with the built in 'exists' operators on
member and variables to enable yet better portability across various
linux flavors.
SGI and other engineering outfits have been cut&pasting kernel code into
sial scripts for years.
The hello worl skeleton for a sial command :
==
string foo_opt(){ return "lt:h"; }
string foo_usage() { return "[-l] [-t counter] [-h]\n"; }
string foo_help(){return " This is the help for command foo\n"}
int
foo()
{
if(tflag) tval=atoi(targ)
if(lflag) {
printf("lflag is set, targ=[%s], targ);
}
printf("Hello world!\n");
}
==
By load'ing this file into crash you automatically create a callable
foo command in crash, complete with help and usage.
Sial can be extended with 'sial builtins' and associated APis.
If there are native crash functions (like back traces and fast searches)
that can be useful as a function in sial, we can do that.

[PATCH] displaying anonymous members of struct/union
by qiaonuohan
Hello Dave,
I have realized the function to display anonymous members of
struct/union. There are three changes, which are listed below, and I
will take "struct page" for example.
1. anonymous members will be showed when using "struct page"
2. anonymous member, "struct page.private", will be showed together with
its offset
3. anonymous member with the address of the structure, "struct
page.private xxx", will be showed.
About the implementation, gdb code is changed, which is used to change
the output of the gdb command, "ptype ...". And function
"arg_to_datatype" is also modified to analyze anonymous member. Please
refer to the patch to get more info about implementation.

Whether crash support extracting file previously stored in the tmpfs?
by Lei Wen
Hi Dave,
Could the crash current support extract the file which was stored in
the tmpfs when the panic happen?
Since we know the tmpfs is purely all in memory, it think it is
ideally that crash could do such job.
Thanks,
Lei
