QUESTION
I was curious about how to catch stack overflows in C and stumble across the GNU libsigseg library.
This library can catch stack overflows on a lot of platforms and provides an implementation example.
In order to install a stack overflow listener with this library, one must first reserve some space for an alternate stack.
From what I understood, this alternate stack is used to run the listener because the real stack is unusable.
The alternate stack is reserved in altstack.h (line 40), and looks like this:
...ANSWER
Answered 2021-Jan-24 at 16:47I don't understand why there is a crumple zone before AND after the stack;
The stack is declared as a global char mystack_storage[...].
Assuming that stack grows down, you need the crumple zone at the low end of storage to detect overflow of the alternate stack itself.
Question: what follows the mystack_storage[] array?
Answer: you don't know.
What if there is another array immediately after, and what if that array is written out of bounds (e.g. with something like other_array[-20] = 'a';)?
To detect such underflow, you need the crumple zone on the other end as well.
How can the stack ends up aligned if we make so it's unaligned?
The mystack pointer is intentionally misaligned. If it was used directly as the alternate stack, it would violate stack alignment requirements on many platforms, and would most likely cause a crash.
To prevent this, the library must not be using mystack directly, but aligning it somewhere else.
The code you pointed to is intended to test that the other code is working properly.
Update:
I still don't understand the offset. Why the mystack pointer would violate stack alignment requirement if used without offset?
Without offset, mystack's alignment is unknown. It may happen to be aligned on 16-byte, 8-byte, or even 1-byte boundary.
With the offset, it is guaranteed to be misaligned (aligned on 1-byte boundary).
Why it isn't the other way around: by adding the offset it's intentionally misaligned and violate stack alignment requirement.
Yes, the pointer is intentionally misaligned.
The point was: the code which actually uses mystack (that code is elsewhere, I didn't look for it), is already prepared for dealing with misaligned mystack, by properly aligning it (let's call that "alignment code"). And the code you pointed to is intended to exercise that other "alignment code".
Now, where is that "alignment code"?
I thought it's somewhere else in the library, but I was wrong. The misaligned mystack pointer is used directly here.
So who is doing the required alignment then? The kernel does!
From man sigaltstack:

I have heard its a conventional practice to store program dependent files in /usr/share/application-folder in linux. So I'm trying to do it in my c program in a function called load_interface_files() for example. I am not sure if this is a good practice or not, I've heard about creating configuration files for this kind of issues.
Anyways, here's the the code I wrote to make a directory in /usr/share.

I am stumbling my way through writing a dissector for our custom protocol in Lua. While I have basic field extraction working, many of our fields have scale factors associated with them. I'd like to present the scaled value in addition to the raw extracted value.
It seems to me tree_item:add_packet_field is tailor-made for this purpose. Except I can't get it to work.
I found Mika's blog incredibly helpful, and followed his pattern for breaking my dissector into different files, etc. That's all working.
Given a packet type "my_packet", I have a 14-bit signed integer "AOA" that I can extract just fine
...ANSWER
Answered 2020-Jul-08 at 21:49Looking at the try_add_packet_field() source code, only certain FT_ types are supported, namely:
FT_BYTESFT_UINT_BYTESFT_OIDFT_REL_OIDFT_SYSTEM_IDFT_ABSOLUTE_TIMEFT_RELATIVE_TIME
None of the other FT_ types are supported [yet], including FT_UINT16, which is the one you're interested in here, i.e., anything else just needs to be done the old fashioned way.
If you'd like this to be implemented, I'd suggest filing a Wireshark enhancement bug request for this over at the Wireshark Bug Tracker.

I would like to search for kill in the gitweb interface of the repository of Bash .

Answered 2019-Jan-06 at 08:38When selecting commit you will search for the character sequence kill in the commit message.
To find kill in the source code you should select grep.
QUESTION
I am trying to implement with Autotools a “multiversion option” for my shared library: in case the user enables it, the library must be able to cohabitate with other versions of itself. That means that the name of the binary must contain the version string, or at least any string that distinguishes it from other versions.
libtool has an option, -release, which does exactly that. However, as explained here, this will not work for my purpose, because at least one file will not have any suffix appended and this will create conflicts with other versions of the package:
4.3. Multiple libraries versionsWhile libtool was designed to handle the presence of multiple libraries implementing the same API (and even ABI) on the system, distributions made that necessity moot. On the other hand, it is not uncommon for multiple versions of a library to be installed, with multiple API implemented, allowing consumers to pick their supported version. This is the case, for instance, of Gtk+ and Glib.
The first reaction would be to combine the two options,
-releaseand-version-info; this would, though, be wrong. When using-releasethe static archive, the one with.aextension, the libtool archive (see Section 6, “Libtool Archives”) and the.sofile used by the link editor would not have a revision appended, which means that two different version of the library can't be installed at the same time.In this situation, the best option is to append part of the library's version information to the library's name, which is exemplified by Glib's
