ipmr: fix incorrect parameter validation in the ip_mroute_getsockopt() function
[ Upstream commit 5c3be3e0eb44b7f978bb6cbb20ad956adb93f736 ]
The 'olr' variable can't be negative when assigned the result of 'min_t' because all 'min_t' parameters are cast to unsigned int, and then the minimum one is chosen.
To fix the logic, check 'olr' as read from 'optlen', where the types of relevant variables are (signed) int.

The original packet in ipmr_cache_report() may be queued and then forwarded with ip_mr_forward(). This last function has the assumption that the skb dst is set.
After the below commit, the skb dst is dropped by ipv4_pktinfo_prepare(), which causes the oops.

ipmr: support IP_PKTINFO on cache report IGMP msg

In order to support IP_PKTINFO on those packets, we need to call ipv4_pktinfo_prepare.
When sending mrouted/pimd daemons a cache report IGMP msg, it is unnecessary to set dst on the newly created skb. It used to be necessary on older versions until commit d826eb14ecef ("ipv4: PKTINFO doesnt need dst reference") which changed the way IP_PKTINFO struct is been retrieved.
Changes from v1: 1. Undo changes in ipv4_pktinfo_prepare function. use it directly and copy the control block.

net: ipv4, ipv6: fix IPSTATS_MIB_OUTOCTETS increment duplicated
commit edf391ff1723 ("snmp: add missing counters for RFC 4293") had already added OutOctets for RFC 4293. In commit 2d8dbb04c63e ("snmp: fix OutOctets counter to include forwarded datagrams"), OutOctets was counted again, but not removed from ip_output().
According to RFC 4293 "3.2.3. IP Statistics Tables", ipipIfStatsOutTransmits is not equal to ipIfStatsOutForwDatagrams. So "IPSTATS_MIB_OUTOCTETS must be incremented when incrementing" is not accurate. And IPSTATS_MIB_OUTOCTETS should be counted after fragment.
This patch reverts commit 2d8dbb04c63e ("snmp: fix OutOctets counter to include forwarded datagrams") and move IPSTATS_MIB_OUTOCTETS to ip_finish_output2 for ipv4.

Merge tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking changes from Jakub Kicinski: "WiFi 7 and sendpage changes are the biggest pieces of work for this release. The latter will definitely require fixes but I think that we got it to a reasonable point.
Core:
- Rework the sendpage & splice implementations
Instead of feeding data into sockets page by page extend sendmsg handlers to support taking a reference on the data, controlled by a new flag called MSG_SPLICE_PAGES
Rework the handling of unexpected-end-of-file to invoke an additional callback instead of trying to predict what the right combination of MORE/NOTLAST flags is
Remove the MSG_SENDPAGE_NOTLAST flag completely
- Implement SCM_PIDFD, a new type of CMSG type analogous to SCM_CREDENTIALS, but it contains pidfd instead of plain pid
- Enable socket busy polling with CONFIG_RT
- Improve reliability and efficiency of reporting for ref_tracker
- Auto-generate a user space C library for various Netlink families
Protocols:
- Allow TCP to shrink the advertised window when necessary, prevent sk_rcvbuf auto-tuning from growing the window all the way up to tcp_rmem[2]
- Use per-VMA locking for "page-flipping" TCP receive zerocopy
- Prepare TCP for device-to-device data transfers, by making sure that payloads are always attached to skbs as page frags
- Make the backoff time for the first N TCP SYN retransmissions linear. Exponential backoff is unnecessarily conservative
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO)
- Avoid waking up applications using TLS sockets until we have a full record
- Allow using kernel memory for protocol ioctl callbacks, paving the way to issuing ioctls over io_uring
- Add nolocalbypass option to VxLAN, forcing packets to be fully encapsulated even if they are destined for a local IP address
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure in-kernel ECMP implementation (e.g. Open vSwitch) select the same link for all packets. Support L4 symmetric hashing in Open vSwitch
- PPPoE: make number of hash bits configurable
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client (ipconfig)
- Add layer 2 miss indication and filtering, allowing higher layers (e.g. ACL filters) to make forwarding decisions based on whether packet matched forwarding state in lower devices (bridge)
- Support matching on Connectivity Fault Management (CFM) packets
- Hide the "link becomes ready" IPv6 messages by demoting their printk level to debug
- HSR: don't enable promiscuous mode if device offloads the proto
- Support active scanning in IEEE 802.15.4
- Continue work on Multi-Link Operation for WiFi 7
BPF:
- Add precision propagation for subprogs and callbacks. This allows maintaining verification efficiency when subprograms are used, or in fact passing the verifier at all for complex programs, especially those using open-coded iterators
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF assumed the length is always equal to the amount of written data. But some protos allow passing a NULL buffer to discover what the output buffer *should* be, without writing anything
- Accept dynptr memory as memory arguments passed to helpers
- Add routing table ID to bpf_fib_lookup BPF helper
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark maps as read-only)
- Show target_{obj,btf}_id in tracing link fdinfo
- Addition of several new kfuncs (most of the names are self-explanatory): - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(), bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size() and bpf_dynptr_clone(). - bpf_task_under_cgroup() - bpf_sock_destroy() - force closing sockets - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter:
- Relax set/map validation checks in nf_tables. Allow checking presence of an entry in a map without using the value
- Increase ip_vs_conn_tab_bits range for 64BIT builds
- Allow updating size of a set
- Improve NAT tuple selection when connection is closing
Driver API:
- Integrate netdev with LED subsystem, to allow configuring HW "offloaded" blinking of LEDs based on link state and activity (i.e. packets coming in and out)
- Support configuring rate selection pins of SFP modules
- Factor Clause 73 auto-negotiation code out of the drivers, provide common helper routines
- Add more fool-proof helpers for managing lifetime of MDIO devices associated with the PCS layer
- Allow drivers to report advanced statistics related to Time Aware scheduler offload (taprio)
- Allow opting out of VF statistics in link dump, to allow more VFs to fit into the message
- Split devlink instance and devlink port operations
New hardware / drivers:
- Ethernet: - Synopsys EMAC4 IP support (stmmac) - Marvell 88E6361 8 port (5x1GE + 3x2.5GE) switches - Marvell 88E6250 7 port switches - Microchip LAN8650/1 Rev.B0 PHYs - MediaTek MT7981/MT7988 built-in 1GE PHY driver

net: ioctl: Use kernel memory on protocol ioctl callbacks
Most of the ioctls to net protocols operates directly on userspace argument (arg). Usually doing get_user()/put_user() directly in the ioctl callback. This is not flexible, because it is hard to reuse these functions without passing userspace buffers.
Change the "struct proto" ioctls to avoid touching userspace memory and operate on kernel buffers, i.e., all protocol's ioctl callbacks is adapted to operate on a kernel memory other than on userspace (so, no more {put,get}_user() and friends being called in the ioctl callback).
This changes the "struct proto" ioctl format in the following way:
int (*ioctl)(struct sock *sk, int cmd, - unsigned long arg); + int *karg);
(Important to say that this patch does not touch the "struct proto_ops" protocols)
So, the "karg" argument, which is passed to the ioctl callback, is a pointer allocated to kernel space memory (inside a function wrapper). This buffer (karg) may contain input argument (copied from userspace in a prep function) and it might return a value/buffer, which is copied back to userspace if necessary. There is not one-size-fits-all format (that is I am using 'may' above), but basically, there are three type of ioctls:
1) Do not read from userspace, returns a result to userspace 2) Read an input parameter from userspace, and does not return anything to userspace 3) Read an input from userspace, and return a buffer to userspace.
The default case (1) (where no input parameter is given, and an "int" is returned to userspace) encompasses more than 90% of the cases, but there are two other exceptions. Here is a list of exceptions:
* Protocol RAW: * cmd = SIOCGETVIFCNT: * input and output = struct sioc_vif_req * cmd = SIOCGETSGCNT * input and output = struct sioc_sg_req * Explanation: for the SIOCGETVIFCNT case, userspace passes the input argument, which is struct sioc_vif_req. Then the callback populates the struct, which is copied back to userspace.
* Protocol RAW6: * cmd = SIOCGETMIFCNT_IN6 * input and output = struct sioc_mif_req6 * cmd = SIOCGETSGCNT_IN6 * input and output = struct sioc_sg_req6
* Protocol PHONET: * cmd == SIOCPNADDRESOURCE | SIOCPNDELRESOURCE * input int (4 bytes) * Nothing is copied back to userspace.
For the exception cases, functions sock_sk_ioctl_inout() will copy the userspace input, and copy it back to kernel space.
The wrapper that prepare the buffer and put the buffer back to user is sk_ioctl(), so, instead of calling sk->sk_prot->ioctl(), the callee now calls sk_ioctl(), which will handle all cases.
