2024-07-29lsm: infrastructure management of the sock securityCasey Schaufler
Move management of the sock->sk_security blob out of the individual security modules and into the security infrastructure. Instead of allocating the blobs from within the modules the modules tell the infrastructure how much space is required, and the space is allocated there.

2023-10-18apparmor: pass cred through to audit info.John Johansen
The cred is needed to properly audit some messages, and will be needed in the future for uid conditional mediation. So pass it through to where the apparmor_audit_data struct gets defined.

2023-10-18apparmor: combine common_audit_data and apparmor_audit_dataJohn Johansen
Everywhere where common_audit_data is used apparmor audit_data is also used. We can simplify the code and drop the use of the aad macro everywhere by combining the two structures. Reviewed-by: Georgia Garcia <georgia.garcia@canonical.com> Signed-off-by: John Johansen <john.johansen@canonical.com>

2022-10-03apparmor: add mediation class information to auditingJohn Johansen
Audit messages currently don't contain the mediation class which can make them less clear than they should be in some circumstances. With newer mediation classes coming this potential confusion will become worse. Fix this by adding the mediatin class to the messages. Signed-off-by: John Johansen <john.johansen@canonical.com>
2020-12-03security: add const qualifier to struct sock in various placesFlorian Westphal
A followup change to tcp_request_sock_op would have to drop the 'const' qualifier from the 'route_req' function as the 'security_inet_conn_request' call is moved there - and that function expects a 'struct sock *'. However, it turns out its also possible to add a const qualifier to security_inet_conn_request instead.

2017-10-26Revert "apparmor: add base infastructure for socket mediation"Linus Torvalds
This reverts commit 651e28c5537abb39076d3949fb7618536f1d242e. This caused a regression: "The specific problem is that dnsmasq refuses to start on openSUSE Leap 42.2. The specific cause is that and attempt to open a PF_LOCAL socket gets EACCES. This means that networking doesn't function on a system with a 4.14-rc2 system." Sadly, the developers involved seemed to be in denial for several weeks about this, delaying the revert. This has not been a good release for the security subsystem, and this area needs to change development practices.
