2017-03-27Smack: fixup of bluetooth socket labellingJosé Bollo1-0/+12
The sockets created by kernel thread will now be tagged @ instead of _. This problem was occuring during creation of AF_BLUETOOTH (but is also latent AF_ALG, AF_IUCV, AF_SCTP, AF_TIPC as they don't go through the normal socket creation process within linux). Having the tag @ allows read/write to sockets without special rules and tus solve the problem. This solution from upstream linux patches backported and from a patch made by Samsung for Tizen and that is currently discussed within kernel lists. Also add some improvements of the LSM Smack (valid caching and signal 0). These improvements are backports of patches already available for linux 4.9-rc3. AGL-bug: SPEC-293 (https://jira.automotivelinux.org/browse/SPEC-293) Change-Id: I5999a951a4bbeba7947ebfe5df091de07d59e57e Signed-off-by: José Bollo <jose.bollo@iot.bzh> Signed-off-by: Stephane Desneux <stephane.desneux@iot.bzh>
