This is https://bugs.debian.org/934763, which i'll work around shortly with the attached patch to the wireguard packaging in 0.0.20190702-2. Thanks to Jason for supplying the attached patch to update the compatibility checks. Note that if you apply the attached patch to wireguard and build against 4.9.168-1+deb9u5, but then try to load the module on a system running 4.9.168-1+deb9u4, the module will fail to load with unrecognized symbols, due to the weird state of the backported siphash (but no hsiphash). --dkg

Donenfeld" <ja...@zx2c4.com> Date: Thu, 15 Aug 2019 06:37:10 +0000 Subject: compat: fix on debian 4.9.168 in sloppy manner Ben backported siphash but forgot to backport hsiphash, which goes into the same .h and .o files, making a proper compat layer for it kind of cumbersome and annoying. Since he plans to backport hsiphash for 4.9.169, this commit is a stop-gap solution for the Debian package. --- src/compat/compat.h | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/compat/compat.h b/src/compat/compat.h index 239fa58..7fc3145 100644 --- a/src/compat/compat.h +++ b/src/compat/compat.h @@ -844,6 +844,12 @@ static inline void skb_mark_not_on_list(struct sk_buff *skb) #define cpu_have_named_feature(name) (elf_hwcap & (HWCAP_ ## name)) #endif +#if LINUX_VERSION_CODE == KERNEL_VERSION(4, 9, 168) +#define hsiphash_2u32 siphash_2u32 +#define hsiphash_3u32 siphash_3u32 +#define hsiphash_key_t siphash_key_t +#endif + /* https://github.com/ClangBuiltLinux/linux/issues/7 */ #if defined( __clang__) && (!defined(CONFIG_CLANG_VERSION) || CONFIG_CLANG_VERSION < 80000) #include <linux/bug.h>
