There is a random crash problem in the repeated connection of webrtc in Android - webrtc

signal 6 (SIGABRT), code -6 (SI_TKILL)
There is a random crash when using webrtc on Android, and my personal skills are limited. Please ask who can help me to see where the problem occurs and how to modify it
Detailed description: Android receives audio and video data on the PC side. When reconnecting for many times, there is a crash from time to time. Specifically, the audio and video are displayed for less than 1 second when the link is connected.
The log does not specifically indicate what is wrong. The specific error log is as follows:

ubuntu 20.04 freeze when compiling kernel modules

I'm using ubuntu20.04 in vmware workstation. I allocate 8 cpu cores, 6G RAM, 4G swap and enough free disk space(at least 25G) to ubuntu20.04. But after running make modules -j4 for about 30 minutes the whole system freezes. The only thing I can do is moving the cursor in virtual machine, the click doesn't get response. When I click "hang up the vm" I get error "cannot hang up vm". After trying several times I can hang it up successsfully. And after I press "continue vm" vm works again but after running about 30 min the situation just occurs again.

I encountered freezing once, by adding RAM I solved the problem. But this time I add RAM to 8G, freezing still occurs. What also confuses me is that my centos vm with 3G RAM and 8 cpu cores run make modules -j8 successfully. I have no idea about the difference.
To check the cpu and memory usage I execute top at the same time. the picture is top's output when freezing occurs. top command output

Where are Kernel global variables stored?

As i know global variables(in userspace programs) are stored in coressponding DATA (and BSS) segment. But how and where are they stored in case of kernel code?

For an example let's look at one of Linux's global variable. Basically, Linux is an ELF image compressed with gzip or other compression tools. As stated on Wikipedia (https://en.wikipedia.org/wiki/Vmlinux):
Traditionally, when creating a bootable kernel image, the kernel is also compressed using gzip, or, since Linux 2.6.30,[3] using LZMA or bzip2, which requires a very small decompression stub to be included in the resulting image. The stub decompresses the kernel code, on some systems printing dots to the console to indicate progress, and then continues the boot process. Support for LZO,[4] xz[5] and LZ4[6] compression was added later.
On Ubuntu, there is a special script called extract-vmlinux which comes with your version of the Linux kernel (https://blog.packagecloud.io/eng/2016/03/08/how-to-extract-and-disassmble-a-linux-kernel-image-vmlinuz/). The Linux ELF file is /boot/vmlinuz. To decompress it, you must use the extract-vmlinux script which can be installed with
sudo apt-get install linux-headers-$(uname -r)
The script is safe to use because it is a standard script which is found in the official repository of packages for your distribution (most packages there are open source and safe). Now use
sudo /usr/src/kernels/$(uname -r)/scripts/extract-vmlinux /boot/vmlinuz-$(uname -r) > vmlinux
to extract the Linux kernel's ELF file from the compressed vmlinux image to your home repository. Now we can look at the ELF file of the Linux kernel. Use readelf -a vmlinux to have a summary of the content. The output for me is this:
user#user-System-Product-Name:~$ readelf -a vmlinux

I would guess that the RW sections are the data/bss segments of the static and freestanding kernel image. There isn't much bss data (uninitialized data) in this kernel image. You can see that by looking at the filesize versus the memsize of the different segments. In bss data, only the size is written in the executable. The loader will then assign zeroes to these segments. Since we have only memsizes which are equal to the filesizes, then we don't have much bss here.
Also, we can look at the different virtual addresses at which the kernel will load itself after decompression. This will be useful to find the segment in which a certain global variable resides.
Now, to determine where a global variable is loaded one can look at the System.map file in the /boot directory. For example, we can take a random global variable in kernel/sched/core.c called sysctl_sched_rt_period and find its address using
user#user-System-Product-Name:~$ sudo grep "sysctl_sched_rt_period" /boot/System.map-$(uname -r)
ffffffff8266eb24 D sysctl_sched_rt_period
The address is thus ffffffff8266eb24. This address resides in the RW segment loaded at ffffffff82600000 because the size of this segment is 37f000 and because ffffffff82600000 + 37f000 > ffffffff8266eb24. You can clearly see that this global variable is stored in the data segment of the kernel's executable.

SSL not working between Linux and Windows

I have gone through loads of material present on internet for SSL. I followed the steps and created self signed certificate on server (linux) using keytool. Server keystore was already having an entry as ( CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown), my new certificate was second entry as ( CN=Server, OU=Server, O=Server, L=Server, ST=Server, C=Server ). Then I exported the certificate(.cer) using keytool and copied same on my client(windows). I then imported server generated certificate to client trustore. Now when I try to communicate using SSL it fails everytime. I turned on SSL debug on client. Below is the log
adding as trusted cert:

When I checked logs carefully I noticed Server is sending only first certificate in chain of certificates to client i.e,. ( CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown ), my newly created certificate is not present. Am I doing something wrong?

Paypal Handshake failure - IBM WCS/WAS

we have updated the SSL protocol to use SSL_TLSv2 (which should allow TLSv1, TLSv1.1 and TLSv1.2) and we are using https://api.sandbox.paypal.com/2.0/ endpoint URL to connect to paypal. We have added VeriSign Class 3 Public Primary Certification Authority - G5 certificate to our keystore. But still we are getting handshake failure.

PANIC: "Oops: 0000 [#1]" (check log for details) - Updated Kernel Tested

I'm trying to interpret a system crash that is repeatable, but but not that often. I believe it has do with a third party driver and a optical scanning device. I'm not sure if the driver for scanning device is causing the hang if it's bringing something out in a USB driver that causes the hang or if it's something totally different.
I'm not a driver developer, so I'm fumbling my way through the crash dump while reading the Linux Kernel Crash Book located here - http://rogunix.com/docs/Reversing&Exploiting/Linux_Kernel_Crash_Book.pdf .
I was able to setup a debug kernel with the kexec tools to produce a vmcore. With crash is see the PANIC: "Oops: 0000 [#1]" (check log for details) and in the logs is see the BUG: unable to handle kernel paging request at virtual address 00100100.
Can you help me interpret more of the dump so I can go back to the developer of the driver and tell them the findings or can you tell me is not the driver at all.
Here's more from the dump. Many thanks in advance.

Updated Kernel Tested
I have since updated to the latest CentOS 5.5 released kernel (2.6.18-371.6.1), but still got a kernel panic. However this time the panic occured on the command "khubd" and not on "swapper". I was able to capture the dump and below I have provided what I hope is relevant information to pinpoint this problem. Is it a bug in the kernel or something in the driver?
