QUESTION

Is it necessary to call set_memory_rw after disabling CR0 "Write Protect" to modify read only pages in Linux kernel?

Asked 2021-Jun-01 at 13:14

Consider the following question on Stack Overflow on system call hooking by modifying the sys_call_table.

https://stackoverflow.com/questions/2103315/linux-kernel-system-call-hooking-example

Since CR0 "Write Protect" (bit 16) controls whether it's possible for the kernel to write to read-only pages, why does some code then calls set_memory_rw to set the permissions for the target pages to RW?

...

ANSWER

Answered 2021-May-12 at 09:53

No.

The CR0.WP method disables write protect support globally, whereas the set_memory_rw method merely adds the write bit to specific pages. If you have already disabled write protection through the control register, then there is no need to do anything else. All kernel memory will be globally writable from within the kernel until you re-enable write protection through the same register.

Make sure you disable interrupts before writing to CR0, then re-enable them afterwards.

Answered 2021-Mar-25 at 19:50

I'm not an usual contributor to S/O but I spent a lot of time fixing this particular problem for someone so I thought it'd be nice if I gave you my solution for this.

zipinfo is likely crashing because there is a preloaded library called libAppProtection, installed in /usr/local, that crashes under the conditions imposed by the AOSP build. I had found a workaround for this particular problem but if the cause of the problem is the same as what I faced, you will have further problems down the line for which you won't find a workaround.

GDB stacktrace of 'fec' another program crashing the same way

In Firefox shows only blank pages - even about:config is just white it describes that the library is related to Citrix Workspace App SDK.

If you observe the same thing I did when running zipinfo or fec (in my case) with GDB, I can only recommend that you remove this program while you deal with building the AOSP sources. I know this has worked and did not cause any drawbacks for the client. Maybe just disabling the preloaded library in /etc/ld.so.preload would work but I have not tried that and since I don't know anything about Citrix, I would advise against doing that.

What's the fastest way to convert a 2D L-system to lines

I'm building a 3D graphics engine, and I want to draw 2D L-systems. But I noticed that this gets quite slow, once you increase the number of iterations. I'm searching a way to rapidly expand my L-system into a vector, with Line a class containing 2 points. this is my current code:

Generally speaking, the first step in optimizing the performance of an application is to profile the code to see where exactly the most time is being spent. Without this step, a lot of effort can be wasted optimizing code that actually has little impact on performance.

However, in this particular case, I would look to simplifying your code so it is easier to see what is going on and so make it easier to interpret the results of performance profiling.

Your recursive function expand could be streamlined by

Moving all those parameters out of the signature. There is no need to place so many copies on the same things on stack!
The first thing a recursive function should do is check if recursion is complete. In this case, check the depth.
The second thing, if further recursion is required, is perform the preparation of the next call. In this case, production of the next string from the current.
Finally, the recursive function can be called.

Below I will post code that implements Lindenmayer's original L-system for modelling the growth of algae. This is much simpler that what you are doing, but hopefully showsthe the method and benefit of re-organizing recursive code into the "standard" style of doing recursion.

Can Eclipse run with Z Garbage Collector?

I tried to change from -XX:+UseG1GC to -XX:+UseZGC in eclipse.ini

...

ANSWER

Answered 2021-Feb-20 at 18:40

The eclipse.ini settings are just used for Eclipse itself, they don't change anything else. To see what Eclipse is using open the "Help > About" dialog ("Eclipse > About" on macOS), click the "Installation Details" button and look at the "Configuration Tab".

For Java programs you run from within Eclipse using the 'Run' command the 'Run Configuration' sets what is used. See the 'VM Arguments' section of the 'Arguments' tab.

You can set default VM arguments for a JRE/JDK in the 'Java > Installed JREs' page of the Preferences.

None of the Eclipse settings changes the options for a 'java' command you run from a terminal.

As stated in this answer, the NO_AUTO_CREATE_USER mode was removed in MySQL 8 (assuming that is the version you're using in Ubuntu 20) and will result in an error if included in your config.

Removing it should fix your error. So the line to be added in your cnf file should be:

The order of libraries on the command line is important - this means that a library containing the definition of a function should appear after any source files or object files which use it. Please see here for more information. Also the comment of @SeanFrancisNBallais is exactly about that.

In your case you need to place the sfml-system-s library after all other SFML libraries, something like below:
