Bug#1010458: linux/sysctl.h: unknown type name 'size_t'
Package: linux-libc-dev
Version: 5.17.3-1
Severity: normal
Tags: upstream
X-Debbugs-Cc: alx.manpa...@gmail.com
I was cleaning up the example programs in the man-pages by using
iwyu(1), when I found that is using 'size_t'
without including any definition for it.
See the following example program:
$ cat tmp/src/man2/sysctl.2.d/sysctl.c
#define _GNU_SOURCE
#include
#include
#include
#include
#include
#include
int _sysctl(struct __sysctl_args *args );
#define OSNAMESZ 100
int
main(void)
{
struct __sysctl_args args;
char osname[OSNAMESZ];
size_t osnamelth;
int name[] = { CTL_KERN, KERN_OSTYPE };
memset(, 0, sizeof(args));
args.name = name;
args.nlen = sizeof(name)/sizeof(name[0]);
args.oldval = osname;
args.oldlenp =
osnamelth = sizeof(osname);
if (syscall(SYS__sysctl, ) == -1) {
perror("_sysctl");
exit(EXIT_FAILURE);
}
printf("This machine is running %*s\n", (int) osnamelth, osname);
exit(EXIT_SUCCESS);
}
for which I get the following errors:
$ cc -c -std=gnu17 -Wall -Wextra -Werror -Wno-error=unused-parameter \
-Wno-error=sign-compare -Wno-error=format \
-o tmp/src/man2/sysctl.2.d/sysctl.o \
tmp/src/man2/sysctl.2.d/sysctl.c;
In file included from tmp/src/man2/sysctl.2.d/sysctl.c:3:

cc1: all warnings being treated as errors
It seems that it's supposed to know some types, but for some reason
'size_t' is not defined by the included headers:
$ grep include
#include

Alex

Bug#974166: 5.9.0-1-amd64 (5.9.11-1) has fixed the issue
Hi, I'm glad to say that just now I upgraded to the unstable kernel: $ sudo apt-get install linux-image-amd64 and now I can boot normally: $ uname -a Linux debian 5.9.0-4-amd64 #1 SMP Debian 5.9.11-1 (2020-11-27) x86_64 GNU/Linux I'm curious: I'd like to see the changelog and the code to see what fixed the issue. Could you point me to it, or give me some hint so that I can search for it myself? Thanks, Alex
Bug#974166: I'd like to help
Hi, I suspect it may have to do with the 5th gen (Broadwell Desktop) only, as they have a very special (and powerful) iGPU. And maybe that's why the bug passed inadvertently so much time: those CPUs didn't sell very well. Yes, I have that package installed: ||/ NameVersion Architecture Description +++-===---=== ii intel-microcode 3.20201110.1 amd64Processor microcode firmware for Intel CPUs When I first upgraded to 5.7, I couldn't boot, and my first thought was: this seems to be such a big bug, so they probably have already noticed, and I didn't report it. It's been more than half a year, kernel 5.9, and the bug is still there, so I strongly suspect that the only affected CPUs are those with Intel Iris Pro 6200 (there are only 4 models with that iGPU).

Bug#974166: I'd like to help
Hi, I received no answer at all, so I guess you are very busy. I know the bug was introduced somewhere between 5.6 and 5.7. If you have an idea of what the source of the bug could be, I'd like to help by testing on my computers, or providing code. I have two computers with similar CPUs (i5-5675C & i7-5775C), and both have the same problem. Basically I'm limited to kernel <= 5.6, right now. I can't boot from a more recent kernel. Thanks, Alex
Bug#974166: Boot logs
I tried booting in recovery mode,
and it also didn't work.
However, I could see the some info.
The 3 last lines of the boot log were:
{
[4.817936] hub 4-0:1.0: 2 ports detected
[4.819372] i915 :00:02.0: [drm] Found 128MB of eDRAM
[4.819882] fb0: switching to inteldrmfb from EFI VGA
}
And then freeze.
These messages are not logged into /var/log/kern.log,
as the system doesn't even boot.
I had to copy them by hand.
Here's what I see when booting with kernel 5.4
at (more or less) the same part of the boot process:

Bug#974166: linux/5.9.6-1 (unstable) has the same bug
I tried installing the new kernel from unstable, but I still can't boot with it. Same problems.
Bug#974166: linux-image-5.9.0-1-amd64: The system goes black when trying to boot graphical mode
Package: src:linux Version: 5.9.1-1 Severity: important X-Debbugs-Cc: alx.manpa...@gmail.com Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? When I upgreeaded from kernel 5.6 to 5.7 a long time ago, my system broke. I first saw some firmware errors when booting. But when I fixed those firmware errors by adding non-free and contrib repos, and installing firmware-linux, those errors disapeared. Now it simply goes black at some point during the boot. If I boot with linux 5.6, however, everything runs fine. * What exactly did you do (or not do) that was effective (or ineffective)? * What was the outcome of this action? * What outcome did you expect instead? Ineffective: Upgrading the kernel to 5.8, or 5.9. None of the kernels >= 5.7 work. Worked: Run with kernel 5.6 (or older). Ineffective: Clean install from DI-alpha2. This provides two kernels: 5.4 (works) and 5.9 (doesn't work). I also tried installing firmware directly from kernel.org: git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git sudo make install but it didn't fix it. *** End of the template - remove these template lines *** -- Package-specific info: ** Kernel log: boot messages should be attached I don't know how to get the boot messages from a system that doesn't boot. ** Model information sys_vendor: ASUS product_name: All Series product_version: System Version chassis_vendor: To Be Filled By O.E.M. chassis_version: To Be Filled By O.E.M. bios_vendor: American Megatrends Inc. bios_version: 2902 board_vendor: ASUSTeK COMPUTER INC. board_name: Z97M-PLUS board_version: Rev X.0x ** Network interface configuration: *** /etc/network/interfaces: source /etc/network/interfaces.d/* auto lo iface lo inet loopback ** PCI devices: 00:00.0 Host bridge [0600]: Intel Corporation Broadwell-U Host Bridge - DMI [8086:1610] (rev 0a) Subsystem: ASUSTeK Computer Inc.
