[PATCH] help: Add 'help -l' to show memory layout

by Rongwei Wang

From: Rongwei Wang <rongwei.wrw(a)gmail.com> 'help -m' can show most of variables which relates to memory layout, e.g. userspace_top, page_offset, vmalloc_start_addr, etc. They aren't a visual way to show a memory layout for kernel space. This patch provides 'help -l' to show memory layout, usage likes: crash> help -l Gap Hole: 0xffffffffff7ff001 - 0xffffffffffffffff Size: 8.0 MB Fixmap Area: 0xffffffffff578000 - 0xffffffffff7ff000 Size: 2.5 MB Gap Hole: 0xffffffffff000001 - 0xffffffffff577fff Size: 5.5 MB Module Area: 0xffffffffa0000000 - 0xffffffffff000000 Size: 1.5 GB Gap Hole: 0xffffffff84826001 - 0xffffffff9fffffff Size: 439.9 MB Kernel Image: 0xffffffff81000000 - 0xffffffff84826000 Size: 56.1 MB Gap Hole: 0xffffeb0000000000 - 0xffffffff80ffffff Size: 21.0 TB Vmemmap Area: 0xffffea0000000000 - 0xffffeaffffffffff Size: 1.0 TB Gap Hole: 0xffffe90000000000 - 0xffffe9ffffffffff Size: 1.0 TB Vmalloc Area: 0xffffc90000000000 - 0xffffe8ffffffffff Size: 32.0 TB Gap Hole: 0xffffc88000000000 - 0xffffc8ffffffffff Size: 512.0 GB Linear Mapping: 0xffff888000000000 - 0xffffc87fffffffff Size: 64.0 TB Linear Gap: 0xffff800000000000 - 0xffff887fffffffff Size: 8.5 TB Gap Hole: 0x0000800000000000 - 0xffff7fffffffffff Size: 16776960.0 TB User Space: 0x0000000000000000 - 0x00007fffffffffff Size: 128.0 TB Signed-off-by: Rongwei Wang <rongwei.wrw(a)gmail.com> --- defs.h | 14 +++- help.c | 7 +- memory.c | 11 +++ x86_64.c | 236 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 266 insertions(+), 2 deletions(-) diff --git a/defs.h b/defs.h index 4fecb83..a3f00d5 100644 --- a/defs.h +++ b/defs.h @@ -4100,12 +4100,23 @@ typedef signed int s32;

[PATCH v2 0/2] extension: Several improvements on eppic extension

by Tao Liu

Eppic works as a crash extension for a long time, and it is a very convenient tool to extend crash's function: 1) People don't need to write an actual crash extension, which requires knowledge of crash APIs, such as readmem(), gdb_interface() etc. Implementing such an crash extension is hard for normal users. 2) Eppic programs are C-syntax-like scripting, no compile needed, so friendly to kernel developers who are already familiar with C. It's a good alternative for people who are unfamiliar with python (comparing to drgn/pykdump). 3) Writing eppic programs is similar to do kernel programming, people can use kernel data structures/global variables directly, again, friendly to kernel developers. Personally I think eppic is a good tool and would like to push it forward to make it used more widely, improved consistently. However I hardly heard anyone who are using it, I guess it is due to it's extension position and unknown to others. In this patchset, I will make several improvements on eppic, although it is still a crash extension, but I think it is made more easily for compile/run/scripting. To-do: Some crash functions should be exposed to eppic, such as maple_tree/rbtree etc, so people can iterate these kernel structures with the existing crash functions, otherwise people need to reimplement those in eppic. A more aggresive improvement of eppic can be found in [1], which people can use call_crash_func() to call any crash's function within eppic script, please refer to code example in [2]. Not sure if people like this, so any feedback/comments are welcomed. v2 -> v1: Removed v1's No.2 & 3 & 5 patch, these 3 are used for compile/preload/alias eppic by default, these are a little aggressive and left to [1] instead.

Reliable Professional Security Services for Your Safety

by florance-james＠proton.me

A professional security service that genuinely redefines peace of mind is something I recently found. Their staff has been dependable, well-trained, and incredibly polite from the first consultation to the continuing protection. Their constant watchfulness guarantees safety around-the-clock, and their obvious presence serves as a powerful deterrent. I didn't realise I was lacking the deep sense of security that this flawless fusion of professionalism and sincere dedication has given me. Visit Site: https://guardianfm.co.uk/security-services/

Alternative Career Paths with a Law Degree in the UK

by timothyl.barnett1＠gmail.com

I was unsure about committing to the conventional solicitor or barrister path after years of obtaining my law degree. My perspective was totally altered when I learnt about the Alternative Careers with a Law Degree UK Service. Under their direction, I was able to see how my research, analysis, and persuasive abilities could be applied to jobs in policy analysis, legal technology, compliance, and other fields. I learnt to view my degree as a strong asset that could open many doors and guide me towards a more rewarding career rather than as a limitation.
