Summary
f2fs: remove clear SB_INLINECRYPT flag in default_options
Details

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

f2fs: remove clear SBINLINECRYPT flag in defaultoptions

In f2fsremount, SBINLINECRYPT flag will be clear and re-set. If create new file or open file during this gap, these files will not use inlinecrypt. Worse case, it may lead to data corruption if wrappedkey_v0 is enable.

Thread A: Thread B:

-f2fsremount -f2fsfileopen or f2fsnewinode -defaultoptions <- clear SB_INLINECRYPT flag

                                      -fscrypt_select_encryption_impl

-parseoptions <- set SBINLINECRYPT again
