[PATCH net-next v7 2/5] bpf: Add tests for eBPF file mode

From: Chenbo Feng Two related tests are added into bpf selftest to test read only map and write only map. The tests verified the read only and write only flags are working on hash maps. Signed-off-by: Chenbo Feng Acked-by: Daniel Borkmann

[PATCH net-next v7 1/5] bpf: Add file mode configuration into bpf maps

From: Chenbo Feng Introduce the map read/write flags to the eBPF syscalls that returns the map fd. The flags is used to set up the file mode when construct a new file descriptor for bpf maps. To not break the backward capability, the f_flags is set to O_RDWR if the flag passed

[PATCH net-next v7 3/5] security: bpf: Add LSM hooks for bpf object related syscall

From: Chenbo Feng Introduce several LSM hooks for the syscalls that will allow the userspace to access to eBPF object such as eBPF programs and eBPF maps. The security check is aimed to enforce a per object security protection for eBPF object so only processes with the right

[PATCH net-next v7 4/5] selinux: bpf: Add selinux check for eBPF syscall operations

From: Chenbo Feng Implement the actual checks introduced to eBPF related syscalls. This implementation use the security field inside bpf object to store a sid that identify the bpf object. And when processes try to access the object, selinux will check if processes have the

[PATCH net-next v7 5/5] selinux: bpf: Add addtional check for bpf object file receive

From: Chenbo Feng Introduce a bpf object related check when sending and receiving files through unix domain socket as well as binder. It checks if the receiving process have privilege to read/write the bpf map or use the bpf program. This check is necessary because the bpf maps

[PATCH net-next v7 0/5] bpf: security: New file mode and LSM hooks for eBPF object permission control

From: Chenbo Feng Much like files and sockets, eBPF objects are accessed, controlled, and shared via a file descriptor (FD). Unlike files and sockets, the existing mechanism for eBPF object access control is very limited. Currently there are two options for granting accessing
