cryptodev not available on kernel 6.1 #96
Comments
|
Cryptodev needs additional work and 6.1 is really fresh (wanted to get kernel itself working for all devices first) :) just have not found time to add it (needs external code added). Do you need it for r2 or other device? As a note: 6.1 for r2 does not support internal wifi |
|
can you please test branch 6.1-cryptodev? at least for r2 compile works using r64 seems also working (compile) using aarch64 crosscompiler... |
|
Hello, Thanks for the answer. Yes it's for R2 (only). Thanks it might be a bit complicated for me to test this, but I will try when I will have some time. |
|
Why is it complicated? It is similar to older kernels...clone repo,change branch to 6.1-cryptodev and then build kernel and cryptodev module,install to your r2 and test it. I have no experience with cryptodev itself,only added code and make it compile |
|
oh sorry, it's just because I'm too busy these time, but yes it's not complicated, it juste take some time. |

The ice driver caches next_to_clean value at the beginning of ice_clean_rx_irq() in order to remember the first buffer that has to be freed/recycled after main Rx processing loop. The end boundary is indicated by first descriptor of frame that Rx processing loop has ended its duties. Note that if mentioned loop ended in the middle of gathering multi-buffer frame, next_to_clean would be pointing to the descriptor in the middle of the frame BUT freeing/recycling stage will stop at the first descriptor. This means that next iteration of ice_clean_rx_irq() will miss the (first_desc, next_to_clean - 1) entries. When running various 9K MTU workloads, such splats were observed: [ 540.780716] BUG: kernel NULL pointer dereference, address: 0000000000000000 [ 540.787787] #PF: supervisor read access in kernel mode [ 540.793002] #PF: error_code(0x0000) - not-present page [ 540.798218] PGD 0 P4D 0 [ 540.800801] Oops: 0000 [#1] PREEMPT SMP NOPTI [ 540.805231] CPU: 18 PID: 3984 Comm: xskxceiver Tainted: G W 6.3.0-rc7+ #96 [ 540.813619] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019 [ 540.824209] RIP: 0010:ice_clean_rx_irq+0x2b6/0xf00 [ice] [ 540.829678] Code: 74 24 10 e9 aa 00 00 00 8b 55 78 41 31 57 10 41 09 c4 4d 85 ff 0f 84 83 00 00 00 49 8b 57 08 41 8b 4f 1c 65 8b 35 1a fa 4b 3f <48> 8b 02 48 c1 e8 3a 39 c6 0f 85 a2 00 00 00 f6 42 08 02 0f 85 98 [ 540.848717] RSP: 0018:ffffc9000f42fc50 EFLAGS: 00010282 [ 540.854029] RAX: 0000000000000004 RBX: 0000000000000002 RCX: 000000000000fffe [ 540.861272] RDX: 0000000000000000 RSI: 0000000000000001 RDI: 00000000ffffffff [ 540.868519] RBP: ffff88984a05ac00 R08: 0000000000000000 R09: dead000000000100 [ 540.875760] R10: ffff88983fffcd00 R11: 000000000010f2b8 R12: 0000000000000004 [ 540.883008] R13: 0000000000000003 R14: 0000000000000800 R15: ffff889847a10040 [ 540.890253] FS: 00007f6ddf7fe640(0000) GS:ffff88afdf800000(0000) knlGS:0000000000000000 [ 540.898465] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 540.904299] CR2: 0000000000000000 CR3: 000000010d3da001 CR4: 00000000007706e0 [ 540.911542] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 540.918789] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 540.926032] PKRU: 55555554 [ 540.928790] Call Trace: [ 540.931276] <TASK> [ 540.933418] ice_napi_poll+0x4ca/0x6d0 [ice] [ 540.937804] ? __pfx_ice_napi_poll+0x10/0x10 [ice] [ 540.942716] napi_busy_loop+0xd7/0x320 [ 540.946537] xsk_recvmsg+0x143/0x170 [ 540.950178] sock_recvmsg+0x99/0xa0 [ 540.953729] __sys_recvfrom+0xa8/0x120 [ 540.957543] ? do_futex+0xbd/0x1d0 [ 540.961008] ? __x64_sys_futex+0x73/0x1d0 [ 540.965083] __x64_sys_recvfrom+0x20/0x30 [ 540.969155] do_syscall_64+0x38/0x90 [ 540.972796] entry_SYSCALL_64_after_hwframe+0x72/0xdc [ 540.977934] RIP: 0033:0x7f6de5f27934 To fix this, set cached_ntc to first_desc so that at the end, when freeing/recycling buffers, descriptors from first to ntc are not missed.

Hello,
I discovered that cryptodev module was not enabled on kernel 6.1. Is it normal ? And is it possible to enable it ?
Thanks
