- Overview
When mounting the attached crafted image and running program, following errors
are reported.
Additionally, it hangs on sync after running program.
The image is intentionally fuzzed from a normal f2fs image for testing.
Compile options for F2FS are as follows.
CONFIG_F2FS_FS=y
CONFIG_F2FS_STAT_FS=y
CONFIG_F2FS_FS_XATTR=y
CONFIG_F2FS_FS_POSIX_ACL=y
# CONFIG_F2FS_FS_SECURITY is not set
CONFIG_F2FS_CHECK_FS=y
# CONFIG_F2FS_FS_ENCRYPTION is not set
# CONFIG_F2FS_FAULT_INJECTION is not set

mkdir test
mount -t f2fs tmp.img test
cp a.out test
cd test
sudo ./a.out
