Bug ID: 102361
Summary: Errors compiling Linux kernel 5.14.4 with
CONFIG_FORTIFY=y
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dac324 at yahoo dot de
Target Milestone: ---
GCC version: gcc (GCC) 12.0.0 20210910 (experimental)
With this version, it is not possible to compile the Linux kernel sources
(tested with both 5.14.1 and 5.14.4).
Problem is that GCC 12 conflicts with CONFIG_FORTIFY=y.
Errors thrown with the 5.14.1 kernel sources:
In function 'memset',
inlined from 'init_rock_state.part.0' at fs/isofs/rock.c:74:2:
./include/linux/fortify-string.h:172:17: error: call to '__write_overflow'
declared with attribute error: detected write beyond size of object passed as
1st parameter
172 | __write_overflow();
| ^~~~~~~~~~~~~~~~~~
make[2]: *** [scripts/Makefile.build:271: fs/isofs/rock.o] Error 1
make[1]: *** [scripts/Makefile.build:514: fs/isofs] Error 2
In function 'memcpy',
inlined from 'tl_to_darg.part.0' at fs/ext4/fast_commit.c:1295:2:
./include/linux/fortify-string.h:187:25: error: call to '__read_overflow2'
declared with attribute error: detected read beyond size of object passed as
2nd parameter
187 | __read_overflow2();
| ^~~~~~~~~~~~~~~~~~
make[2]: *** [scripts/Makefile.build:271: fs/ext4/fast_commit.o] Error 1
make[1]: *** [scripts/Makefile.build:514: fs/ext4] Error 2
Error thrown with the 5.14.4 kernel sources:
In Function »memcpy«,
inserted from von »tl_to_darg.part.0« bei fs/ext4/fast_commit.c:1295:2:
./include/linux/fortify-string.h:187:25: Error: call to »__read_overflow2«
declared with attribute error: detected read beyond size of object passed as
2nd parameter
187 | __read_overflow2();
| ^~~~~~~~~~~~~~~~~~
With GCC 11, these errors do not occur. Hence, I must assume that they are
related to the compiler version.

Please isolate a pre-processed source file (-E) option and attach it here
together with the used command line.

Please let me kindly ask you for instructions on how to do that.
As described in the introduction, I was trying to compile the Linux kernel from
the usual source tarball available on kernel.org.
What I did after extracting the sources was:
make menuconfig
make
If I understand correctly, I will have to interrupt the make process to extract
a pre-processed source file?
Please let me kindly ask for additional guidance.
Thank you very much and kind regards.

See https://gcc.gnu.org/bugs/
On the kernel side, I guess you want to use make V=1 so that it shows the
compiler command lines, then copy & paste relevant command both here and into
command line where you add -save-temps to it to get preprocessed source.

This is the first error; if make is used with -j greater than 1, several of
those errors occur (see introduction).

--- Comment #13 from DAC324 <dac324 at yahoo dot de> ---
Sorry for duplicate reporting. For me, the error message
'__write_overflow' declared with attribute error: detected write beyond size of
object passed as 1st parameter
and its counterpart
'__read_overflow2' declared with attribute error: detected read beyond size of
object passed as 2nd parameter
did not point me to using
fnsplit fragment with __attribute__((__error__))
as a correct search term, in the first instance.
Please apologize for the inconvenience.
Just FYI (although I assume you know this already):
With CONFIG_FORTIFY=n, you will be able to build the kernel but it will not run
satisfactorily, if able to boot at all.

It is ok, it is good that you filed the bug. I have been doing a lot of
cleanup of GCC's bugzilla lately so I have some memory of some of the more
recent bugs filed. Searching bugzilla to know if there was a dup filed is a
huge task even so I don't think most people will be doing it.
