Linux kernel source tree
b937186679
Fix a buffer overflow issue in qcom_clear_bam_transaction by using
struct_group to group related fields and avoid FORTIFY_SOURCE warnings.
On x86 architecture, the following error occurs due to warnings being
treated as errors:
In function ‘fortify_memset_chk’,
inlined from ‘qcom_clear_bam_transaction’ at
drivers/mtd/nand/qpic_common.c:88:2:
./include/linux/fortify-string.h:480:25: error: call to ‘__write_overflow_field’
declared with attribute warning: detected write beyond size of field
(1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
480 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
LD [M] drivers/mtd/nand/nandcore.o
CC [M] drivers/w1/masters/mxc_w1.o
cc1: all warnings being treated as errors
This patch addresses the issue by grouping the related fields in
struct bam_transaction using struct_group and updating the memset call
accordingly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
