Summary
f2fs: assign CURSEG_ALL_DATA_ATGC if blkaddr is valid
Details

In the Linux kernel, the following vulnerability has been resolved:

f2fs: assign CURSEGALLDATA_ATGC if blkaddr is valid

mkdir /mnt/test/comp f2fs_io setflags compression /mnt/test/comp dd if=/dev/zero of=/mnt/test/comp/testfile bs=16k count=1 truncate --size 13 /mnt/test/comp/testfile

In the above scenario, we can get a BUGON. kernel BUG at fs/f2fs/segment.c:3589! Call Trace: dowritepage+0x78/0x390 [f2fs] f2fsoutplacewritedata+0x62/0xb0 [f2fs] f2fsdowritedatapage+0x275/0x740 [f2fs] f2fswritesingledatapage+0x1dc/0x8f0 [f2fs] f2fswritemultipages+0x1e5/0xae0 [f2fs] f2fswritecachepages+0xab1/0xc60 [f2fs] f2fswritedatapages+0x2d8/0x330 [f2fs] dowritepages+0xcf/0x270 __writebacksingleinode+0x44/0x350 writebacksbinodes+0x242/0x530 __writebackinodeswb+0x54/0xf0 wbwriteback+0x192/0x310 wbworkfn+0x30d/0x400

The reason is we gave CURSEGALLDATAATGC to COMPRADDR where the page was set the gcing flag by setclusterdirty().
