2017-10-27net: dsa: define port typesVivien Didelot3-0/+16
Introduce an enumerated type for ports, which will be way more explicit to identify a port type instead of digging into switch port masks. A port can be of type CPU, DSA, user, or unused by default. This is a static parsed information that cannot be changed at runtime. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-10-27net: dsa: introduce dsa_user_ports helperVivien Didelot6-8/+11
Introduce a dsa_user_ports() helper to return the ds->enabled_port_mask mask which is more explicit. This will also minimize diffs when touching this internal mask. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-10-27net: dsa: use dsa_is_user_port everywhereVivien Didelot6-13/+12
Most of the DSA code still check ds->enabled_port_mask directly to inspect a given port type instead of using the provided dsa_is_user_port helper. Change this.

2017-10-27net: dsa: rename dsa_is_normal_port helperVivien Didelot2-2/+2
This patch renames dsa_is_normal_port to dsa_is_user_port because "user" is the correct term in the DSA terminology, not "normal".

2017-10-27net: dsa: fix dsa_is_normal_port helperVivien Didelot1-1/+1
In order to know if a port is of type user, dsa_is_normal_port checks that the given port is not of type DSA nor CPU. This is not enough because a port can be unused. Without the previous fix, this caused the unused mv88e6xxx ports to be configured in normal mode. The ds->enabled_port_mask reports the user ports, so check this instead.

2017-10-27net: dsa: mv88e6xxx: skip unused portsVivien Didelot1-0/+3
The unused ports are currently configured in normal mode. This does not prevent the switch from being functional, but it is unnecessary. Skip unused ports.

2017-10-27net: dsa: add dsa_is_unused_port helperVivien Didelot2-1/+8
As the comment above the chunk states, the b53 driver attempts to disable the unused ports. But using ds->enabled_port_mask is misleading, because this mask reports in fact the user ports. To avoid confusion and fix this, this patch introduces an explicit dsa_is_unused_port helper which ensures the corresponding bit is not masked in any of the switch port masks.

2017-10-27bpf: remove tail_call and get_stackid helper declarations from bpf.hGianluca Borello2-3/+2
commit afdb09c720b6 ("security: bpf: Add LSM hooks for bpf object related syscall") included linux/bpf.h in linux/security.h. As a result, bpf programs including bpf_helpers.h and some other header that ends up pulling in also security.h, such as several examples under samples/bpf, fail to compile because bpf_tail_call and bpf_get_stackid are now "redefined as different kind of symbol". >From bpf.h: u64 bpf_tail_call(u64 ctx, u64 r2, u64 index, u64 r4, u64 r5); u64 bpf_get_stackid(u64 r1, u64 r2, u64 r3, u64 r4, u64 r5); Whereas in bpf_helpers.h they are: static void (*bpf_tail_call)(void *ctx, void *map, int index); static int (*bpf_get_stackid)(void *ctx, void *map, int flags); Fix this by removing the unused declaration of bpf_tail_call and moving the declaration of bpf_get_stackid in bpf_trace.c, which is the only place where it's needed.

2017-10-27liquidio: deprecate 1-bit flag indicating watchdog kernel thread is runningFelix Manlunas1-10/+4
Deprecate the 1-bit flag (bit 2 in the SLI_SCRATCH_1 Octeon register) that indicates that the liquidio watchdog kernel thread is running for this NIC. Reason is: it is incompatible with the firmware's use for SLI_SCRATCH_1. In lieu of checking that now-deprecated flag, check the value of oct_dev->adapter_refcount to determine whether or not to create the watchdog kernel thread.
