From 2a1c9e20bd38572ba32ba57436d7064192680729 Mon Sep 17 00:00:00 2001 From: Martin Willi Date: Wed, 15 Oct 2014 17:22:55 +0200 Subject: kernel-interface: Remove reqid parameter from get_spi/get_cpi() methods The reqid is not strictly required, as we set the reqid with the update call when installing the negotiated SA. If we don't need a reqid at this stage, we can later allocate the reqid in the kernel backend once the SA parameters have been fully negotaited. This allows us to assign the same reqid for the same selectors to avoid conflicts on backends this is necessary. --- src/libcharon/plugins/kernel_wfp/kernel_wfp_ipsec.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/libcharon/plugins/kernel_wfp/kernel_wfp_ipsec.c') diff --git a/src/libcharon/plugins/kernel_wfp/kernel_wfp_ipsec.c b/src/libcharon/plugins/kernel_wfp/kernel_wfp_ipsec.c index 39e37b1c9..61e820dea 100644 --- a/src/libcharon/plugins/kernel_wfp/kernel_wfp_ipsec.c +++ b/src/libcharon/plugins/kernel_wfp/kernel_wfp_ipsec.c @@ -1981,7 +1981,7 @@ static u_int permute(u_int x, u_int p) METHOD(kernel_ipsec_t, get_spi, status_t, private_kernel_wfp_ipsec_t *this, host_t *src, host_t *dst, - u_int8_t protocol, u_int32_t reqid, u_int32_t *spi) + u_int8_t protocol, u_int32_t *spi) { /* To avoid sequencial SPIs, we use a one-to-one permuation function on * an incrementing counter, that is a full period PRNG for the range we @@ -1998,7 +1998,7 @@ METHOD(kernel_ipsec_t, get_spi, status_t, METHOD(kernel_ipsec_t, get_cpi, status_t, private_kernel_wfp_ipsec_t *this, host_t *src, host_t *dst, - u_int32_t reqid, u_int16_t *cpi) + u_int16_t *cpi) { return NOT_SUPPORTED; } -- cgit v1.2.3
