From 798b2cbf9227b1bd7d37ae9af4d9c750e6f4de9c Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 4 Sep 2012 14:20:14 -0400 Subject: 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. ==================== Reported-by: Stephen Rothwell Signed-off-by: David S.
