Hoang Le f845fe5819 Revert "tipc: use consistent GFP flags" ... This reverts commit 86c3a3e964. The tipc_aead_init() function can be calling from an interrupt routine. This allocation might sleep with GFP_KERNEL flag, hence the following BUG is reported. [ 17.657509] BUG: sleeping function called from invalid context at include/linux/sched/mm.h:230 [ 17.660916] in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 0, name: swapper/3 [ 17.664093] preempt_count: 302, expected: 0 [ 17.665619] RCU nest depth: 2, expected: 0 [ 17.667163] Preemption disabled at: [ 17.667165] [<0000000000000000>] 0x0 [ 17.669753] CPU: 3 PID: 0 Comm: swapper/3 Kdump: loaded Tainted: G W 5.16.0-rc4+ #1 [ 17.673006] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 [ 17.675540] Call Trace: [ 17.676285] <IRQ> [ 17.676913] dump_stack_lvl+0x34/0x44 [ 17.678033] __might_resched.cold+0xd6/0x10f [ 17.679311] kmem_cache_alloc_trace+0x14d/0x220 [ 17.680663] tipc_crypto_start+0x4a/0x2b0 [tipc] [ 17.682146] ? kmem_cache_alloc_trace+0xd3/0x220 [ 17.683545] tipc_node_create+0x2f0/0x790 [tipc] [ 17.684956] tipc_node_check_dest+0x72/0x680 [tipc] [ 17.686706] ? ___cache_free+0x31/0x350 [ 17.688008] ? skb_release_data+0x128/0x140 [ 17.689431] tipc_disc_rcv+0x479/0x510 [tipc] [ 17.690904] tipc_rcv+0x71c/0x730 [tipc] [ 17.692219] ? __netif_receive_skb_core+0xb7/0xf60 [ 17.693856] tipc_l2_rcv_msg+0x5e/0x90 [tipc] [ 17.695333] __netif_receive_skb_list_core+0x20b/0x260 [ 17.697072] netif_receive_skb_list_internal+0x1bf/0x2e0 [ 17.698870] ? dev_gro_receive+0x4c2/0x680 [ 17.700255] napi_complete_done+0x6f/0x180 [ 17.701657] virtnet_poll+0x29c/0x42e [virtio_net] [ 17.703262] __napi_poll+0x2c/0x170 [ 17.704429] net_rx_action+0x22f/0x280 [ 17.705706] __do_softirq+0xfd/0x30a [ 17.706921] common_interrupt+0xa4/0xc0 [ 17.708206] </IRQ> [ 17.708922] <TASK> [ 17.709651] asm_common_interrupt+0x1e/0x40 [ 17.711078] RIP: 0010:default_idle+0x18/0x20 Fixes: 86c3a3e964 ("tipc: use consistent GFP flags") Acked-by: Jon Maloy <jmaloy@redhat.com> Signed-off-by: Hoang Le <hoang.h.le@dektech.com.au> Link: https://lore.kernel.org/r/20211217030059.5947-1-hoang.h.le@dektech.com.au Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2021-12-17 19:18:48 -08:00
