The ucma users supply timeout in u32 format, it means that any number with most significant bit set will be converted to negative value by various rdma_*, cma_* and sa_query functions, which treat timeout as int. In the lowest level, the timeout is converted back to be unsigned long. Remove this ambiguous conversion by updating all function signatures to receive unsigned long. Reported-by:

IPCB should be cleared before icmp_send, since it may contain data from previous layers and the data could be misinterpreted as ip header options, which later caused the ihl to be set to an invalid value and resulted in the following stack corruption: [ 1083.031512] ib0: packet len 57824 (> 2048) too long to send, dropping [ 1083.031843] ib0: packet len 37904 (> 2048) too long to send, dropping [ 1083.032004] ib0: packet len 4040 (> 2048) too long to send, dropping [ 1083.032253] ib0: packet len 63800 (> 2048) too long to send, dropping [ 1083.032481] ib0: packet len 23960 (> 2048) too long to send, dropping [ 1083.033149] ib0: packet len 63800 (> 2048) too long to send, dropping [ 1083.033439] ib0: packet len 63800 (> 2048) too long to send, dropping [ 1083.033700] ib0: packet len 63800 (> 2048) too long to send, dropping [ 1083.034124] ib0: packet len 63800 (> 2048) too long to send, dropping [ 1083.034387] ================================================================== [ 1083.034602] BUG: KASAN: stack-out-of-bounds in __ip_options_echo+0xf08/0x1310 [ 1083.034798] Write of size 4 at addr ffff880353457c5f by task kworker/u16:0/7 [ 1083.034990] [ 1083.035104] CPU: 7 PID: 7 Comm: kworker/u16:0 Tainted: G O 4.19.0-rc5+ #1 [ 1083.035316] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Ubuntu-1.8.2-1ubuntu2 04/01/2014 [ 1083.035573] Workqueue: ipoib_wq ipoib_cm_skb_reap [ib_ipoib] [ 1083.035750] Call Trace: [ 1083.035888] dump_stack+0x9a/0xeb [ 1083.036031] print_address_description+0xe3/0x2e0 [ 1083.036213] kasan_report+0x18a/0x2e0 [ 1083.036356] ? __ip_options_echo+0xf08/0x1310 [ 1083.036522] __ip_options_echo+0xf08/0x1310 [ 1083.036688] icmp_send+0x7b9/0x1cd0 [ 1083.036843] ? icmp_route_lookup.constprop.9+0x1070/0x1070 [ 1083.037018] ? netif_schedule_queue+0x5/0x200 [ 1083.037180] ? debug_show_all_locks+0x310/0x310 [ 1083.037341] ? rcu_dynticks_curr_cpu_in_eqs+0x85/0x120 [ 1083.037519] ? debug_locks_off+0x11/0x80 [ 1083.037673] ? debug_check_no_obj_freed+0x207/0x4c6 [ 1083.037841] ? check_flags.part.27+0x450/0x450 [ 1083.037995] ? debug_check_no_obj_freed+0xc3/0x4c6 [ 1083.038169] ? debug_locks_off+0x11/0x80 [ 1083.038318] ? skb_dequeue+0x10e/0x1a0 [ 1083.038476] ? ipoib_cm_skb_reap+0x2b5/0x650 [ib_ipoib] [ 1083.038642] ? netif_schedule_queue+0xa8/0x200 [ 1083.038820] ? ipoib_cm_skb_reap+0x544/0x650 [ib_ipoib] [ 1083.038996] ipoib_cm_skb_reap+0x544/0x650 [ib_ipoib] [ 1083.039174] process_one_work+0x912/0x1830 [ 1083.039336] ? wq_pool_ids_show+0x310/0x310 [ 1083.039491] ? lock_acquire+0x145/0x3a0 [ 1083.042312] worker_thread+0x87/0xbb0 [ 1083.045099] ? process_one_work+0x1830/0x1830 [ 1083.047865] kthread+0x322/0x3e0 [ 1083.050624] ? kthread_create_worker_on_cpu+0xc0/0xc0 [ 1083.053354] ret_from_fork+0x3a/0x50 For instance __ip_options_echo is failing to proceed with invalid srr and optlen passed from another layer via IPCB [ 762.139568] IPv4: __ip_options_echo rr=0 ts=0 srr=43 cipso=0 [ 762.139720] IPv4: ip_options_build: IPCB 00000000f3cd969e opt 000000002ccb3533 [ 762.139838] IPv4: __ip_options_echo in srr: optlen 197 soffset 84 [ 762.139852] IPv4: ip_options_build srr=0 is_frag=0 rr_needaddr=0 ts_needaddr=0 ts_needtime=0 rr=0 ts=0 [ 762.140269] ================================================================== [ 762.140713] IPv4: __ip_options_echo rr=0 ts=0 srr=0 cipso=0 [ 762.141078] BUG: KASAN: stack-out-of-bounds in __ip_options_echo+0x12ec/0x1680 [ 762.141087] Write of size 4 at addr ffff880353457c7f by task kworker/u16:0/7 Signed-off-by:

A user can provide a hint which will be attached to the packet and written to the CQE on receive. This can be used as a way to offload operations into the HW, for example parsing a packet which is a tunneled packet, and if so, pass 0x1 as the hint. The software can use that hint to decapsulate the packet and parse only the inner headers thus saving CPU cycles. Signed-off-by:

Verify that the input DEVX object type matches the created object. As the obj_id in the firmware is not globally unique the object type must be considered upon checking for a valid object id. Once both the type and the id match we know that the lock was taken on the correct object by the uverbs layer.

Tracking CM_ID resource is performed in two stages: creation of cm_id and connecting it to the cma_dev. It is needed because rdma-cm protocol exports two separate user-visible calls rdma_create_id and rdma_accept. At the time of CM_ID creation, the real owner of that object is unknown yet and we need to grab task_struct. This task_struct is released or reassigned in attach phase later on. but call to rdma_destroy_id left this task_struct unreleased. Such separation is unique to CM_ID and other restrack objects initialize in one shot. It means that it is safe to use "res->valid" check to catch unfinished CM_ID flow and release task_struct for that object. Fixes: 00313983 ("RDMA/nldev: provide detailed CM_ID information") Reported-by:

This patch moves hfi1_copy_sge() into rdmavt for sharing with qib. This patch also moves all the wss_*() functions into rdmavt as several wss_*() functions are called from hfi1_copy_sge() When SGE copy mode is adaptive, cacheless copy may be done in some cases for performance reasons. In those cases, X86 cacheless copy function is called since the drivers that use rdmavt and may set SGE copy mode to adaptive are X86 only. For this reason, this patch adds "depends on X86_64" to rdmavt/Kconfig. Reviewed-by:

The hip08 hardware has two version. the version id are 0x20 and 0x21 according to the pci revision. It needs to adjust some fields for extending new features. The specific updates include: 1. Add some fields for supporting new features by enabling some reserved fields in 0x20 version. 2. remove some fields which the user is not visiable in order to support the extend features. 3. Init some fields with zero. These updates is compatible with 0x20 version. Signed-off-by:
