Thanks for the report, I've pushed the following change to net-next
which should address this:
--------------------
[PATCH] net: Add INET dependency on aes crypto for the sake of TCP fastopen.
Stephen Rothwell says:
====================
After merging the final tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:
net/built-in.o: In function `tcp_fastopen_ctx_free':
tcp_fastopen.c:(.text+0x5cc5c): undefined reference to `crypto_destroy_tfm'
net/built-in.o: In function `tcp_fastopen_reset_cipher':
(.text+0x5cccc): undefined reference to `crypto_alloc_base'
net/built-in.o: In function `tcp_fastopen_reset_cipher':
(.text+0x5cd6c): undefined reference to `crypto_destroy_tfm'
Presumably caused by commit 104671636897 ("tcp: TCP Fast Open Server -
header & support functions") from the net-next tree. I assume that some
dependency on the CRYPTO infrastructure is missing.
I have reverted commit 1bed966cc3bd ("Merge branch
'tcp_fastopen_server'") for today.
