The Controversial Speck Encryption Code Will Indeed Be Dropped From The Linux Kernel
After Google reverted their plans to use Speck for file-system encryption, it was called for removal from the Linux kernel with no other serious users of this code... Speck had been added to the crypto code in Linux 4.17 and then to the fscrypt bits for file-system encryption with Linux 4.18.
But during the Linux 4.19 merge window that ended a week ago, the removal of Speck never occurred.
While it didn't happen for this current kernel cycle, I noticed today that the speck removal patch has been merged into the development crypto code base by subsystem maintainer Herbert Xu. The patch merged overnight strips the kernel of Speck.
This along with the start of other early crypto code will end up being merged into the next kernel cycle though the patch is also marked for stable back-porting to currently supported stable series.
