Summary

f2fs: remove WARN_ON in f2fs_is_valid_blkaddr

Details

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

f2fs: remove WARNON in f2fsisvalidblkaddr

Syzbot triggers two WARNs in f2fsisvalid_blkaddr and _isbitmapvalid. For example, in f2fsisvalidblkaddr, if type is DATAGENERICENHANCE or DATAGENERICENHANCEREAD, it invokes WARNON if blkaddr is not in the right range. The call trace is as follows:

f2fsgetnodeinfo+0x45f/0x1070 readnode_page+0x577/0x1190 __getnodepage.part.0+0x9e/0x10e0 __getnodepage f2fsgetnodepage+0x109/0x180 doreadinode f2fsiget+0x2a5/0x58b0 f2fsfillsuper+0x3b39/0x7ca0

Fix these two WARNs by replacing WARNON with dumpstack.
