X-Git-Tag: v2.6.26-rc1~1138^2~86 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=2c8dd11636e3a5f14a7fb765331b7043f01fe937;p=linux-2.6-omap-h63xx.git [XFRM]: Compilation warnings in xfrm_user.c. When CONFIG_SECURITY_NETWORK_XFRM is undefined the following warnings appears: net/xfrm/xfrm_user.c: In function 'xfrm_add_pol_expire': net/xfrm/xfrm_user.c:1576: warning: 'ctx' may be used uninitialized in this function net/xfrm/xfrm_user.c: In function 'xfrm_get_policy': net/xfrm/xfrm_user.c:1340: warning: 'ctx' may be used uninitialized in this function (security_xfrm_policy_alloc is noop for the case). It seems that they are result of the commit 03e1ad7b5d871d4189b1da3125c2f12d1b5f7d0b ("LSM: Make the Labeled IPsec hooks more stack friendly") Signed-off-by: Denis V. Lunev Signed-off-by: David S.
