random: ignore GRND_RANDOM in getentropy(2)

2022-06-22T12:11:03Z

commit 48446f198f9adcb499b30332488dfd5bc3f176f6 upstream. The separate blocking pool is going away. Start by ignoring GRND_RANDOM in getentropy(2). This should not materially break any API. Any code that worked without this change should work at least as well with this change.

bpf: Make dst_port field in struct bpf_sock 16-bit wide

2022-04-15T12:18:32Z

[ Upstream commit 4421a582718ab81608d8486734c18083b822390d ] Menglong Dong reports that the documentation for the dst_port field in struct bpf_sock is inaccurate and confusing. From the BPF program PoV, the field is a zero-padded 16-bit integer in network byte order. The value appears to the BPF user as if laid out in memory as so: offsetof(struct bpf_sock, dst_port) + 0 + 8 +16 0x00 +24 0x00 32-, 16-, and 8-bit wide loads from the field are all allowed, but only if the offset into the field is 0. 32-bit wide loads from dst_port are especially confusing. The loaded value, after converting to host byte order with bpf_ntohl(dst_port), contains the port number in the upper 16-bits. Remove the confusion by splitting the field into two 16-bit fields. For backward compatibility, allow 32-bit wide loads from offsetof(struct bpf_sock, dst_port). While at it, allow loads 8-bit loads at offset [0] and [1] from dst_port.

commit bfa26ba343c727e055223be04e08f2ebdd43c293 upstream. Numerous keyboards are adding dictate keys which allows for text messages to be dictated by a microphone.

xfrm: enforce validity of offload input flags

2022-03-08T18:07:47Z

commit 7c76ecd9c99b6e9a771d813ab1aa7fa428b3ade1 upstream. struct xfrm_user_offload has flags variable that received user input, but kernel didn't check if valid bits were provided. It caused a situation where not sanitized input was forwarded directly to the drivers. For example, XFRM_OFFLOAD_IPV6 define that was exposed, was used by strongswan, but not implemented in the kernel at all. As a solution, check and sanitize input flags to forward XFRM_OFFLOAD_INBOUND to the drivers.
