Test that an integer is different from two other integers in eBPF without branch opcodes

Asked 2022-Mar-30 at 14:22

I'm writing an eBPF kprobe that checks task UIDs, namely that the only permitted UID changes between calls to execve are those allowed by setuid(), seteuid() and setreuid() calls.

Since the probe checks all tasks, it uses an unrolled loop that iterates starting from init_task, and it has to use at most 1024 or 8192 branches, depending on kernel version.

My question is, how to implement a check that returns nonzero if there is an illegal change, defined by:

You should be able to do this using bitwise OR, XOR, shifts and integer multiplication. I assume your variables are all __s32 or __u32, cast them to __u64 before proceeding to avoid problems (otherwise cast every operand of the multiplications below to __u64).

Clearly a != b can become a ^ b. The && is a bit trickier, but can be translated into a multiplication (where if any operand is 0 the result is 0). The first part of your condition then becomes:

Your question's answer:

You can treat characters in a Raku regex literally by surrounding them with quotes (e.g., '.*?') or by using using regular variable interpolation (e.g., $substring inside the regex where $substring is a string contaning metacharacters).

Thus, to translate the Perl program with \Q...\E from your question into Raku, you could write:

Animate needle transition

Asked 2022-Mar-21 at 22:09

When I read data from GPS sensor, it comes with a slight delay. You are not getting values like 0,1 0,2 0,3 0,4 0,5 etc, but they are coming like 1 then suddenly 5 or 9 or 12. In this case needle is jumping back and forth. Anybody have an idea how to make needle moving smoothly? I guess some kind of delay is needed?

Coming from a controls background, to mimic behavior of an analog device, you could use an exponential (aka low-pass) filter.

There are two types of low-pass filters you can use, depending on what type of behavior you want to see: a first-order or second-order filter. To put it in a nutshell, if your reading was steady at 0 then suddenly changed to 10 and held steady at 10 (a step change), the first order would slowly go to 10, never passing it, then remain at 10 whereas the second order would speed up its progress towards 10, pass it, then oscillate in towards 10.

The function for an exponential filter is simple:

ANSWER

Answered 2022-Mar-17 at 15:43

Here are some leading questions that can help you reach the answer. Answers to the questions after a break:

Where does the jmp rel -1 instruction jump to?
What does the target instruction do? What happens after it?
How did this instruction end up in the program section of the memory?

jmp rel -1 is encoded in the memory at addresses 5-6. When it is executed, we have pc = 5, thus after the jump we will execute the instruction at pc = 4, which is 0x48307fff7fff8000.
This bytecode encodes the instruction [ap] = [ap - 1] + [ap - 1]; ap++ (to check, you can manually decode the flags and offsets, or simply write a cairo program with this instruction and see what it compiles to). After it is executed, pc is increased by 1, so we again execute jmp rel -1, and so on in an infinite loop. It should be clear why this fills the memory with powers of 2 (the first 2, at address 10, was written by the [fp + 1] = 2; ap++ instruction).
The instruction [fp] = 5201798304953761792; ap++ has an immediate argument (the right hand side, 5201798304953761792). Instructions with immediate arguments are encoded as two field elements in the memory, the first encoding the general instruction (e.g. [fp] = imm; ap++), and the second being the immediate value itself. This immediate value is thus written in address 4, and indeed 5201798304953761792 is the same as 0x48307fff7fff8000. Similarly, the 2 at address 2 is the immediate argument of the instruction [fp + 1] = 2, and the -1 at address 6 is the immediate of jmp rel -1.

To summarize, this strange behavior is due to the relative jump moving to an address of an immediate value and parsing it as a standalone instruction. Normally this wouldn't occur, since pc is incremented by 2 after executing an instruction with an immediate value, and by 1 when executing an instruction without one, so it always continues to the next compiled instruction. The unlabeled jump was necessary here to reach this unexpected program counter.

QUESTION

Android Studio Disconnects From Physical Device

Asked 2022-Mar-06 at 15:11

Android Studio Bumblebee (2021.1.1) was released stably on 25 January 2022 bundled with a new Device Manager (accompanying new support for Android 11+ device debugging over WIFI). I jumped on this stable release, updating from Android Studio Arctic Fox (2020.3.1 Patch 4).

Unfortunately however, since updating, physical devices/handsets don't remain connected to Android Studio for the purpose of debugging. I can confirm that the issue was introduced from Android Studio Bumblebee onwards (occurring in Beta and Canary builds also). I've reproduced the issue on Android Studio Bumblebee (Stable), Chipmunk (Beta), and Dolphin (Canary), but Android Studio Arctic Fox (superseded Stable) continues to work just fine.

The issue occurs soon after opening Android Studio (Bumblebee+) with one of my physical devices connected. Everything appears fine initially and I may even have enough time to deploy my project to the handset, before the device disappears from Android Studio (as if I'd physically disconnected the USB cable from my computer or from the handset itself).

I've tried a fair few things in an attempt to determine a root cause. These include testing:

With different USB cables.
With different handsets (both varying makes and models).
With various versions of the Android Studio IDE (as mentioned above).
Plugging the USB cables into different USB ports on my computer.
Rebooting handsets and my computer.
Restarting Android Studio.
Invalidating caches and restarting Android Studio.
adb kill-server then adb start-server.
Revoking/reaccepting USB debugging authorization.
Reinstalled build tools/platform tools, and ADB.
A great number of further possibilities, to no avail.

I searched and read through remotely similar issues, including (but not limited to) these:

This particular comment in one of the above issues clued me onto a possible root cause:

I have been fighting for a few days with adb not seeing my device. After trying many other posted solutions, I discovered that the issue was with Chrome also trying to connect its debugger to a web view. If Chrome is connected using chrome://inspect, then adb seems to disconnect. Quitting Chrome resolves the issue. Then I can connect with Android Studio and then restart Chrome and reconnect. Hope this helps someone else.

However I've been unable to do anything with the above discovery, other than close Google Chrome, and hope for the best. Obviously this isn't an ideal solution. It appears as though the moment Google Chrome shows the connected physical device in the chrome://inspect/#devices page, the physical device promptly becomes unavailable through Android Studio.

I've jumped back to Android Studio Arctic Fox (2020.3.1 Patch 4) for the moment, however this brings with it other issues (my current core project targets the latest SDK version, which requires the updated IDE).

Absolutely any help with this would be insanely appreciated. I've exhausted just about every avenue that I can think of!

You could add -Weffc++ to catch it (inspired by Scott Meyers book "Effective C++"). Strangely enough it does not refer to any other -W option (and neither does clang++).

The option is however considered, by some, a bit outdated by now, but in this case, it's finding a real problem.

Convert GPS Coordinates to Match Custom 2d outdoor layout Image

Asked 2022-Jan-17 at 04:19

I don't know if this is possible, but I am trying to take the image of a custom outdoor football field layout and have the players' GPS coordinates correspond to the image xand y position. This way, it can be viewed via the app to show the players' current location on the field as a sort of live tracking.

I have also looked into this Convert GPS coordinates to coordinate plane. The problem is that I don't know if this would work and wanted to confirm beforehand. The image provided in the post was for indoor location, and it was from 11 years ago.

I used Location and Google Maps packages for flutter. The player's latitude and longitude correspond to the actual latitude and longitude that the simulator in the android studio shows when tested.

The layout in question and a close comparison to the result I am looking for.

Any help on this matter would be appreciated highly, and thanks in advance for all the help.

Edit:

After looking more at the matter I tried the answer of this post GPS Conversion - pixel coords to GPS coords, but it wasn't working as intended. I took some points on the image and the correspond coordinates, and followed the same logic that the answer used, but reversed it to give me the actual image X, Ypositions.

Answered 2022-Jan-12 at 08:20

First of All, Yes you can do this with high accuracy if the GPS coordinates are accurate.

Second, the main problem is rotation if the field are straight with lat lng lines this would be easy and straightforward (no bun intended).

The easy way is to convert coordinate to rotated image similar to the real field then rotated every X,Y point to the new straight image. (see the image below)

Here is how to rotate x,y knowing the angel:

How to allow to use the master password in Laravel 8 by overriding Auth structure?

Asked 2022-Jan-03 at 05:36

I've got a website written in pure PHP and now I'm learning Laravel, so I'm remaking this website again to learn the framework. I have used built-in Auth Fasade to make authentication. I would like to understand, what's going on inside, so I decided to learn more by customization. Now I try to make a master password, which would allow direct access to every single account (as it was done in the past).

Unfortunately, I can't find any help, how to do that. When I was looking for similar issues I found only workaround solutions like login by admin and then switching to another account or solution for an older version of Laravel etc.

I started studying the Auth structure by myself, but I lost and I can't even find a place where the password is checked. I also found the very expanded solution on GitHub, so I tried following it step by step, but I failed to make my own, shorter implementation of this. In my old website I needed only one row of code for making a master password, but in Laravel is a huge mountain of code with no change for me to climb on it.

As far I was trying for example changing all places with hasher->check part like here:

ANSWER

Answered 2021-Dec-07 at 09:52

The assembly seems to be checking if either num or den is larger than 2**32 by shifting right by 32 bits and then checking whether the resulting number is 0. Depending on the decision, a 64-bit division (div rsi) or 32-bit division (div esi) is performed.

Presumably this code is generated because the compiler writer thinks the additional checks and potential branch outweigh the costs of doing an unnecessary 64-bit division.
