Undefined reference to symbol in hand-written ELF file

Asked 2021-Jun-03 at 15:38

I have hand-written an ELF32 object file that I would like to link via. gcc but I get an undefined reference when I try to use my function/label. I have it defined in a test C file as extern yet this does not change anything.

This object file contains the following assembly:

Terminals have 3 file descriptors by default:

Standard input, a.k.a. stdin
Standard output, a.k.a. stdout
Standard error, a.k.a. stderr

When redirecting >/dev/null it actually redirects the standard output to /dev/null, which is strictly equivalent to 1>/dev/null

However the program may also output to the standard error, in which case you may want to add 2>/dev/null to suppress stderr messages:

I think you're on the right track but

You may have your ?:s reversed
You may need to take the total for each category, and
Not use the overall total

QUESTION

Sending data over ESP_NOW

Asked 2021-May-24 at 13:22

I'm a total noob and just starting out with PlatformIO and Arduino/ESP32. I also want to say thanks in advance to any help I can get.

Plan:

I have 2 ESP32's talking over ESP_NOW, I just can't verify the data being sent in order to progress with my project. Basically, I have a Nextion display that sends specific info to an ESP32 (tested and working) and that ESP32 is then to send that information via ESP_NOW to the other ESP32 which will translate it into serial data to send to an Arduino Due and perform some tasks.

Problem:

The issue I have is that when I test, I see the data I think I am transmitting, but when I try to Serial.print said info, I get "0 0 0 0". I'm not sure that I am sending OR receiving the data properly. All I know is that when I press the button on the Nextion, I get a response on the ESP32 that is not connected.

Code:

Lua can be compiled both as C ans C++ languages. This is an advertised feature of it. For that reason, Lua authors decided not to include the classic extern "C" in the headers.

Your liblua5.2.so.5.2 library was compiled in C language and the symbols are not mangled. You compiled your application in C++ mode with just including Lua headers without extern "C", so your Lua included symbols are mangled.

Solution: wrap your include with extern "C":

From Prometheus side, metrics can be distinguished by their label and saved separately, although the more you get the worse scrape performance you will have if that matters for you.

QUESTION

How to reverse R_X86_64_JUMP_SLOT relocations?

Asked 2021-Mar-26 at 03:55

I am building an ELF binary which needs to be able to process and reverse its own relocations at runtime. (The reversing will happen in a separate buffer, not in the original code page, obviously.) The purpose of this is so that the module contents in memory can be HMAC'd and compared against a known good value calculated from the module on disk, to ensure no corruption has occurred. I'm aware that this is somewhat unusual, but it's a requirement of a standard that we have to adhere to.

I've been able to reverse all of the relocations in the binary except for the R_X86_64_JUMP_SLOT relocations which happen in the Global Offset Table. . Looking at the relocation entries in my test module's .rela.plt section with readelf -a mylib.so, I see these relocations:

...

ANSWER

Answered 2021-Mar-26 at 03:55

You can sidestep the problem by compiling with -fno-plt so you don't have any PLT entries at all, and the associated lazy-binding machinery doesn't come into play.

GCC and clang will use call *printf@GOTPCREL(%rip) which forces early binding: resolving the GOT entries on process startup. This makes each call more efficient, and some distros (e.g. Arch GNU/Linux) are compiling their packages this way already.

TL:DR: This is generally a good option, it's just not on by default (yet) in current GCC and clang distro configs.

Calculating new column value in dataframe based on next row's column value
