2023-10-02RDMA/siw: Annotate struct siw_pbl with __counted_byKees Cook
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct siw_pbl.

2023-09-11RDMA/siw: Fix connection failure handlingBernard Metzler
In case immediate MPA request processing fails, the newly created endpoint unlinks the listening endpoint and is ready to be dropped. This special case was not handled correctly by the code handling the later TCP socket close, causing a NULL dereference crash in siw_cm_work_handler() when dereferencing a NULL listener. We now also cancel the useless MPA timeout, if immediate MPA request processing fails. This patch furthermore simplifies MPA processing in general: Scheduling a useless TCP socket read in sk_data_ready() upcall is now surpressed, if the socket is already moved out of TCP_ESTABLISHED state.

2023-08-22RDMA/siw: Balance the reference of cep->kref in the error pathGuoqing Jiang
The siw_connect can go to err in below after cep is allocated successfully: 1. If siw_cm_alloc_work returns failure. In this case socket is not assoicated with cep so siw_cep_put can't be called by siw_socket_disassoc. We need to call siw_cep_put twice since cep->kref is increased once after it was initialized. 2. If siw_cm_queue_work can't find a work, which means siw_cep_get is not called in siw_cm_queue_work, so cep->kref is increased twice by siw_cep_get and when associate socket with cep after it was initialized. So we need to call siw_cep_put three times (one in siw_socket_disassoc). 3. siw_send_mpareqrep returns error, this scenario is similar as 2. So we need to remove one siw_cep_put in the error path.

2023-07-21RDMA/siw: Fabricate a GID on tun and loopback devicesChuck Lever
LOOPBACK and NONE (tunnel) devices have all-zero MAC addresses. Currently, siw_device_create() falls back to copying the IB device's name in those cases, because an all-zero MAC address breaks the RDMA core address resolution mechanism. However, at the point when siw_device_create() constructs a GID, the ib_device::name field is uninitialized, leaving the MAC address to remain in an all-zero state. Fabricate a random artificial GID for such devices, and ensure this artificial GID is returned for all device query operations.

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.

Make it clearer what is going on by adding a function to go back from the "virtual" dma_addr to a kva and another to a struct page. This is used in the ib_uses_virt_dma() style drivers (siw, rxe, hfi, qib). Call them instead of a naked casting and virt_to_page() when working with dma_addr values encoded by the various ib_map functions. This also fixes the virt_to_page() casting problem Linus Walleij has been chasing.

2022-11-30RDMA/siw: remove FOLL_FORCE usageDavid Hildenbrand
GUP now supports reliable R/O long-term pinning in COW mappings, such that we break COW early. MAP_SHARED VMAs only use the shared zeropage so far in one corner case (DAXFS file with holes), which can be ignored because GUP does not support long-term pinning in fsdax (see check_vma_flags()). Consequently, FOLL_FORCE | FOLL_WRITE | FOLL_LONGTERM is no longer required for reliable R/O long-term pinning: FOLL_LONGTERM is sufficient. So stop using FOLL_FORCE, which is really only for ptrace access.

2022-11-15RDMA/siw: Set defined status for work completion with undefined statusBernard Metzler
A malicious user may write undefined values into memory mapped completion queue elements status or opcode. Undefined status or opcode values will result in out-of-bounds access to an array mapping siw internal representation of opcode and status to RDMA core representation when reaping CQ elements. While siw detects those undefined values, it did not correctly set completion status to a defined value, thus defeating the whole purpose of the check. This bug leads to the following Smatch static checker warning: drivers/infiniband/sw/siw/siw_cq.c:96 siw_reap_cqe() error: buffer overflow 'map_cqe_status' 10 <= 21 Fixes: bdf1da5df9da ("RDMA/siw: Fix immediate work request flush to completion queue") Link: https://lore.kernel.org/r/20221115170747.1263298-1-bmt@zurich.ibm.com Reported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Bernard Metzler <bmt@zurich.ibm.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

Correctly set send queue element opcode during immediate work request flushing in post sendqueue operation, if the QP is in ERROR state. An undefined ocode value results in out-of-bounds access to an array for mapping the opcode between siw internal and RDMA core representation in work completion generation. It resulted in a KASAN BUG report of type 'global-out-of-bounds' during NFSoRDMA testing. This patch further fixes a potential case of a malicious user which may write undefined values for completion queue elements status or opcode, if the CQ is memory mapped to user land. It avoids the same out-of-bounds access to arrays for status and opcode mapping as described above.
