2022-09-16net/ieee802154: fix uninit value bug in dgram_sendmsgHaimin Zhang1-19/+23
There is uninit value bug in dgram_sendmsg function in net/ieee802154/socket.c when the length of valid data pointed by the msg->msg_name isn't verified. We introducing a helper function ieee802154_sockaddr_check_size to check namelen. First we check there is addr_type in ieee802154_addr_sa. Then, we check namelen according to addr_type. Also fixed in raw_bind, dgram_bind, dgram_connect. Signed-off-by: Haimin Zhang <tcs_kernel@tencent.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-08-29genetlink: start to validate reserved header bytesJakub Kicinski2-0/+2
We had historically not checked that genlmsghdr.reserved is 0 on input which prevents us from using those precious bytes in the future. One use case would be to extend the cmd field, which is currently just 8 bits wide and 256 is not a lot of commands for some core families. To make sure that new families do the right thing by default put the onus of opting out of validation on existing families.

2022-04-12net: remove noblock parameter from recvmsg() entitiesOliver Hartkopp1-4/+2
The internal recvmsg() functions have two parameters 'flags' and 'noblock' that were merged inside skb_recv_datagram(). As a follow up patch to commit f4b41f062c42 ("net: remove noblock parameter from skb_recv_datagram()") this patch removes the separate 'noblock' parameter for recvmsg(). Analogue to the referenced patch for skb_recv_datagram() the 'flags' and 'noblock' parameters are unnecessarily split up with e.g. err = sk->sk_prot->recvmsg(sk, msg, size, flags & MSG_DONTWAIT, flags & ~MSG_DONTWAIT, &addr_len); or in err = INDIRECT_CALL_2(sk->sk_prot->recvmsg, tcp_recvmsg, udp_recvmsg, sk, msg, size, flags & MSG_DONTWAIT, flags & ~MSG_DONTWAIT, &addr_len); instead of simply using only flags all the time and check for MSG_DONTWAIT where needed (to preserve for the formerly separated no(n)block condition).

2022-04-06net: remove noblock parameter from skb_recv_datagram()Oliver Hartkopp1-2/+4
skb_recv_datagram() has two parameters 'flags' and 'noblock' that are merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)' As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags' into 'flags' and 'noblock' with finally obsolete bit operations like this: skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc); And this is not even done consistently with the 'flags' parameter. This patch removes the obsolete and costly splitting into two parameters and only performs bit operations when really needed on the caller side. One missing conversion thankfully reported by kernel test robot. I missed to enable kunit tests to build the mctp code.

2022-03-03net: ipv6: Handle delivery_time in ipv6 defragMartin KaFai Lau1-0/+1
A latter patch will postpone the delivery_time clearing until the stack knows the skb is being delivered locally (i.e. calling skb_clear_delivery_time() at ip_local_deliver_finish() for IPv4 and at ip6_input_finish() for IPv6). That will allow other kernel forwarding path (e.g. ip[6]_forward) to keep the delivery_time also. A very similar IPv6 defrag codes have been duplicated in multiple places: regular IPv6, nf_conntrack, and 6lowpan. Unlike the IPv4 defrag which is done before ip_local_deliver_finish(), the regular IPv6 defrag is done after ip6_input_finish(). Thus, no change should be needed in the regular IPv6 defrag logic because skb_clear_delivery_time() should have been called. 6lowpan also does not need special handling on delivery_time because it is a non-inet packet_type. However, cf_conntrack has a case in NF_INET_PRE_ROUTING that needs to do the IPv6 defrag earlier. Thus, it needs to save the mono_delivery_time bit in the inet_frag_queue which is similar to how it is handled in the previous patch for the IPv4 defrag. This patch chooses to do it consistently and stores the mono_delivery_time in the inet_frag_queue for all cases such that it will be easier for the future refactoring effort on the IPv6 reasm code.

2021-07-23net: socket: rework compat_ifreq_ioctl()Arnd Bergmann1-2/+2
compat_ifreq_ioctl() is one of the last users of copy_in_user() and compat_alloc_user_space(), as it attempts to convert the 'struct ifreq' arguments from 32-bit to 64-bit format as used by dev_ioctl() and a couple of socket family specific interpretations. The current implementation works correctly when calling dev_ioctl(), inet_ioctl(), ieee802154_sock_ioctl(), atalk_ioctl(), qrtr_ioctl() and packet_ioctl(). The ioctl handlers for x25, netrom, rose and x25 do not interpret the arguments and only block the corresponding commands, so they do not care. For af_inet6 and af_decnet however, the compat conversion is slightly incorrect, as it will copy more data than the native handler accesses, both of them use a structure that is shorter than ifreq. Replace the copy_in_user() conversion with a pair of accessor functions to read and write the ifreq data in place with the correct length where needed, while leaving the other ones to copy the (already compatible) structures directly.

2020-06-13treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada2-4/+4
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
