Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to wait on block writeback for post_read case
If inode is compressed, but not encrypted, it missed to call
f2fs_wait_on_block_writeback() to wait for GCed page writeback
in IPU write path.
Thread A GC-Thread
- f2fs_gc
- do_garbage_collect
- gc_data_segment
- move_data_block
- f2fs_submit_page_write
migrate normal cluster's block via
meta_inode's page cache
- f2fs_write_single_data_page
- f2fs_do_write_data_page
- f2fs_inplace_write_data
- f2fs_submit_page_bio
IRQ
- f2fs_read_end_io
IRQ
old data overrides new data due to
out-of-order GC and common IO.
- f2fs_read_end_io
