I am currently facing the hardest bug chase of my young developer career. The software we provide is used only in the company internally having several hundred users / computers, but only on one the software does not work. The problematic program is based on MFC and uses OpenInventor for 3D visualisation.
When the user starts the software and creates a new file, internally a new CDocument is created connect to a view that uses/displays an SoWinFullViewer. The user can see that frame of the MFC view is created but the SoWinFullViewer is not displayed. In this state the whole application freezes.
I am unable to reproduce the issue on my developing machine or on any other computer.
For debugging, I deployed an debug build on the problematic computer. But the debug build runs fine. So I deployed a release build with debugging symboles and used the Remote Debugger from Visual Studio. When I start the release build via Remote Debugger everything works fine. If I start the program first on the problematic computer manually, then attach the process via Remote Debugger and then create the new file, the program freezes. After pausing the program, the debugger stands always in a thread of nvwgf2umx.dll.
I expected an issue with the GPU driver, so I let the IT reinstalled the GPU drivers. The problem stayed alive. The only option I see right now is to let the IT reinstall the whole system - praying that this will solve the issue.
What can I do for further debugging? What can cause an application to freeze inside nvwgf2umx.dll ?
Based on the comment I pulled a dump and analyzed it with WinDbg. This is the result of
!analyze -v :

This tells me that a breakpoint in nvoglv64.dll was hit. The Stack Text shows only external code. What could cause that?

Is there a way to generate a sharepoint backup online using azure functions?
I have already authenticated the tenant using managed identity
The idea would be to download all the files in the documents and upload them to an azure storage account
I used this code but I get an error:
using namespace System.Net
param($Request, $TriggerMetadata)
$TenantSiteURL = "https://tenant.sharepoint.com"
$SiteRelativeURL = "/sites/BackupSource"

I used the mutex to synchronize the two kernel threads. After running, panic occurred in the system and abnormal memory was found in mutex by kdump.
Here is a simplified code example, You can run it directly to reproduce the problem.
I changed the memory allocation method to use kmalloc instead of vmalloc, and then it worked, Who knows why？

I am working with a SoC FPGA. In the past I have been testing some peripherals through polling, and now I want to work with interrupts.
I have followed some tutorials and now I have a driver which can detect interrupts on the IRQ 72. The problem is that I want to reply to that IRQ and I have been trying different things but none seems to work.
The last attempt was about a C program which would do the logic part, I mean, it will perform some action when the Kernel tells it an interrupt is present. This program is writting it's PID on a file, I want the kernel to read the PID to send the program a SIGUSR1 signal, and then the program will do smth.
Kernel module:

kernel[1283]: [ 63.144843] Code: bad PC value
I am sure there are better ways and I would like to hear them. For example, I also tried to implement the logic on the IRQ handler, but... failed.
EDIT:
I changed a little bit my code as #suren99 suggested, I also added some printk to debug, and now i get this:
root#socfpga:~/leer# insmod leer.ko
[ 527.785020] Opened the file successfully
[ 527.788953] Value of ret is: -22
[ 527.792438] The PID is: ▒▒▒8A▒▒�#
[ 527.792476] test_int: La IRQ 41 va a ser registrada!
I must add that...
ret = kernel_read(fp, offset, buf, 512);
Why this is "-22"?
printk("The PID is: %s", buf);
If I printk this, then the answer is this: ▒▒▒8A▒▒�#
printk("The PID is: %s", *buf);
And if put this, then the pointer returns "null".
What am I doing wrong?
First of all, you shouldn't check the return value of filp_open with NULL. You should check if the call has succeeded by using IS_ERR()
if (IS_ERR(f)) {
pr_err("Error opening file")
}
I believe the file_open has returned an error pointer and you are trying to dereference it
f->f_op->read(f, buf, 128, &f->f_pos);
Alternatively, you can use addr2line to find which line has caused the kernel panic
I create a package that contains 22 equal applets.(The applets are equal in program and different in AID.)
When I set the package AID and applet's AIDs as below, everything is OK. (I can install it and I can see it in the response of gp -list command)
Package AID = 0102030405
App1 AID = 010203040501

As you see above, the list of applets of my package doesn't appear in output(I think it is a feature of SD of my card), but I have output without any error.
I think the card is the origin of the error! No?
Note that, This problem appear only in cases that the package contains more than 20 applets.
If you have troubles with specific software, please follow the documentation of the software to get help (this includes posting to the right place and posting with sufficient information, like logs with -d -v for GlobalPlatformPro and do open a github issue if you think you have found a bug)
If you have questions about JavaCard or GlobalPlatform, please read the specifications before asking questions that are explained in the specs (like different VM limitations).
I have a program that is just a TCP data forwarder. Data packets come in from one source and are buffered intelligently for redistribution to multiple clients. There are a few threads, and there's some mutex'ing going on. There's also a little logging to disk. But mostly it's just TCP socket data (no UDP despite what the dmesg seems to imply). Also, there's no blocking. It's all select on non-blocking sockets and some polling.
This process is hung up. Although it responds to SNMP requests (there are dedicated threads for that) and will accept client connections (there's a dedicated listener thread), no data will flow. Note that this program will run for a month with no problems before it finally hangs up, so it's really hard to probe with a debug version. I'm really hoping someone can help me interpret the dmesg reports I have, because this is all I have go go on.

#5 0x00b95a09 in start_thread () from /lib/libpthread.so.0
#6 0x00ad343e in clone () from /lib/libc.so.6
There are 6 more threads. One is the listener thread, and the rest are for SNMP. I don't know how to get more stack frame info to tell what the duration of the sleep is, but there are limits placed on it. In one place, the longest sleep is capped at 5 seconds. Others are hard-coded to 1 second and 5 milliseconds. There are no blocking calls to access sockets. Mutexes are involved, but this one system ran for like a month with no clients attached, which means that blocking on locks would be very rare.
Below is an excerpt from dmesg. Everything before it is related to boot-up, and there's nothing after except for a segfault for an unrelated process. This is my only clue about what's going on, and I really hope someone can help me make sense of it. (I added some blank lines for readability.)
