When commit [1] was added, SGID was queried to derive the SMAC address. Then, later on during a refactor [2], SMAC was no longer needed. However, the now useless GID query remained. Then during additional code changes later on, the GID query was being done in such a way that it caused iWARP queries to start breaking. Remove the useless GID query and resolve the iWARP breakage at the same time. This is discussed in [3]. [1] commit dd5f03be ("IB/core: Ethernet L2 attributes in verbs/cm structures") [2] commit 5c266b23 ("IB/cm: Remove the usage of smac and vid of qp_attr and cm_av") [3] https://www.spinics.net/lists/linux-rdma/msg63951.htmlSuggested-by:

When the kernel was compiled using the UBSAN option, we saw the following stack trace: [ 1184.827917] UBSAN: Undefined behaviour in drivers/infiniband/hw/mlx4/mr.c:349:27 [ 1184.828114] signed integer overflow: [ 1184.828247] -2147483648 - 1 cannot be represented in type 'int' The problem was caused by calling round_up in procedure mlx4_ib_umem_calc_optimal_mtt_size (on line 349, as noted in the stack trace) with the second parameter (1 << block_shift) (which is an int). The second parameter should have been (1ULL << block_shift) (which is an unsigned long long). (1 << block_shift) is treated by the compiler as an int (because 1 is an integer). Now, local variable block_shift is initialized to 31. If block_shift is 31, 1 << block_shift is 1 << 31 = 0x80000000=-214748368. This is the most negative int value. Inside the round_up macro, there is a cast applied to ((1 << 31) - 1). However, this cast is applied AFTER ((1 << 31) - 1) is calculated. Since (1 << 31) is treated as an int, we get the negative overflow identified by UBSAN in the process of calculating ((1 << 31) - 1). The fix is to change (1 << block_shift) to (1ULL << block_shift) on line 349. Fixes: 9901abf5 ("IB/mlx4: Use optimal numbers of MTT entries") Signed-off-by:

When allocating device data, if there's an allocation failure, the already allocated memory won't be freed such as per-cpu counters. Fix memory leaks in exception path by creating a common reentrant clean up function hfi1_clean_devdata() to be used at driver unload time and device data allocation failure. To accomplish this, free_platform_config() and clean_up_i2c() are changed to be reentrant to remove dependencies when they are called in different order. This helps avoid NULL pointer dereferences introduced by this patch if those two functions weren't reentrant. In addition, set dd->int_counter, dd->rcv_limit, dd->send_schedule and dd->tx_opstats to NULL after they're freed in hfi1_clean_devdata(), so that hfi1_clean_devdata() is fully reentrant.

When an invalid num_vls is used as a module parameter, the code execution follows an exception path where the macro dd_dev_err() expects dd->pcidev->dev not to be NULL in hfi1_init_dd(). This causes a NULL pointer dereference. Fix hfi1_init_dd() by initializing dd->pcidev and dd->pcidev->dev earlier in the code. If a dd exists, then dd->pcidev and dd->pcidev->dev always exists.

AHG may be armed to use the stored header, which by design is limited to edits in the PSN/A 32 bit word (bth2). When the code is trying to send a BECN, the use of the stored header will lose the BECN bit. Fix by avoiding AHG when getting ready to send a BECN. This is accomplished by always claiming the packet is not a middle packet which is an AHG precursor. BECNs are not a normal case and this should not hurt AHG optimizations.

The code for handling a marked UD packet unconditionally returns the dlid in the header of the FECN marked packet. This is not correct for multicast packets where the DLID is in the multicast range. The subsequent attempt to send the CNP with the multicast lid will cause the chip to halt the ack send context because the source lid doesn't match the chip programming. The send context will be halted and flush any other pending packets in the pio ring causing the CNP to not be sent. A part of investigating the fix, it was determined that the 16B work broke the FECN routine badly with inconsistent use of 16 bit and 32 bits types for lids and pkeys. Since the port's source lid was correctly 32 bits the type mixmatches need to be dealt with at the same time as fixing the CNP header issue. Fix these issues by: - Using the ports lid for as the SLID for responding to FECN marked UD packets - Insure pkey is always 16 bit in this and subordinate routines - Insure lids are 32 bits in this and subordinate routines Cc: <stable@vger.kernel.org> # 4.14.x Fixes: 88733e3b ("IB/hfi1: Add 16B UD support") Reviewed-by:

Håkon Bugge authored
Currently, the kernel protects access to the agent ID allocator on a per port basis using a spinlock, so it is impossible for two apps/threads on the same port to get the same TID, but it is entirely possible for two threads on different ports to end up with the same TID. As this can be confusing (regardless of it being legal according to the IB Spec 1.3, C13-18.1.1, in section 13.4.6.4 - TransactionID usage), and as the rdma-core user space API for /dev/umad devices implies unique TIDs even across ports, make the TID an atomic type so that no two allocations, regardless of port number, will be the same.

So it is not necessary to call kfree_skb in soft roce module again. Or else crash will occur.

There are few issues with validation of netdevice and listen id lookup for IB (IPoIB) while processing incoming CM request as below. 1. While performing lookup of bind_list in cma_ps_find(), net namespace of the netdevice can get deleted in cma_exit_net(), resulting in use after free access of idr and/or net namespace structures. This lookup occurs from the workqueue context (and not userspace context where net namespace is always valid). CPU0 CPU1 ==== ==== bind_list = cma_ps_find(); move netdevice to new namespace delete net namespace cma_exit_net() idr_destroy(idr); [..] cma_find_listener(bind_list, ..); 2. While netdevice is validated for IP address in given net namespace, netdevice's net namespace and/or ifindex can change in cma_get_net_dev() and cma_match_net_dev(). Above issues are overcome by using rcu lock along with netdevice UP/DOWN state as described below. When a net namespace is getting deleted, netdevice is closed and shutdown before moving it back to init_net namespace. change_net_namespace() synchronizes with any existing use of netdevice before changing the netdev properties such as net or ifindex. Once netdevice IFF_UP flags is cleared, such fields are not guaranteed to be valid. Therefore, rcu lock along with netdevice state check ensures that, while route lookup and cm_id lookup is in progress, netdevice of interest won't migrate to any other net namespace. This ensures that associated net namespace of netdevice won't get deleted while rcu lock is held for netdevice which is in IFF_UP state.

In commit bcf87f1d ("IB/mlx5: Listen to netdev register/unresiter events in switchdev mode") incorrectly mapped primary device's netdevice to 2nd port netdevice. It always represented primary port's netdevice for 2nd port netdevice when ib representors were not used. This results into failing to process CM request arriving on 2nd port due to incorrect mapping of netdevice. This fix corrects it by considering the right mdev.
