SOF HDA/HDMI enabling -- Part1 #101

keyonjie · 2018-08-29T11:43:44Z

This part is the major part:

enable HDA bus initialization and codec probing.
use hda_ext_stream and expand SOF stream management to support HDA stream.
make sure it doesn't break the existed DSP non-HDA mode.

The later part(will send PR after this is merged) will include:

DPIB position update.
Legacy HDA/HDMI mode support.

E.g. for snd_hdac_ext_link_clear_stream_id(), we should set (1 << stream) as mask, and 0 as value, here correct it and several similar mismatches. And, here also remove unreadable register_mask usage for those mask value updating. Signed-off-by: Keyon Jie <[email protected]>

@lgirdwood can you help review this?

-			(int)PTR_ERR(priv->pdev_pcm));
-	}
+	sof_create_platform_device(priv);


Need to check return value.

this callback function actually will be removed in the next commit.

but let me remove this change here in the update versions.

@keyonjie feel free to squash these patches per file if it makes things easier. They will be upstreamed as a single patch per file.

hdac_bus library. In some cases, we want to initialize hda bus without this hdac_bus library(e.g. for non-HDA I2S only usuage on Intel Skylake+ platforms), where we will do hdac bus non-HDA-only implementation in BSD license. When we want to add hda link support(GPL) in this implementation, we need reuse this process_unsol_events(), so export it is better solution comparing to implement it again.

OK, good point, I thought about that but didn't do in that way yet. Thanks.

@lgirdwood it is updated.
what I have minor concern is the commit:
ALSA: HDA: export process_unsol_events() which can be used without hdac_bus library

I discussed with Mengdong about it, we think better to export this library function and reuse it in SOF.

redundant copy_from_user in rds_sendmsg system call expose rds to issue where rds_rdma_extra_size walk the rds iovec and and calculate the number pf pages (sgs) it need to add to the tail of rds message and later rds_cmsg_rdma_args copy the rds iovec again and re calculate the same number and get different result causing WARN_ON in rds_message_alloc_sgs. fix this by doing the copy_from_user only once per rds_sendmsg system call.

packet_sendmsg() checks tx_ring.pg_vec to decide if it must call tpacket_snd(). Problem is that the check is lockless, meaning another thread can issue a concurrent setsockopt(PACKET_TX_RING ) to flip tx_ring.pg_vec back to NULL. Given that tpacket_snd() grabs pg_vec_lock mutex, we can perform the check again to solve the race. syzbot reported : kasan: CONFIG_KASAN_INLINE enabled kasan: GPF could be caused by NULL-ptr deref or user memory access general protection fault: 0000 [#1] PREEMPT SMP KASAN CPU: 1 PID: 11429 Comm: syz-executor394 Not tainted 5.3.0-rc4+ #101 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 RIP: 0010:packet_lookup_frame+0x8d/0x270 net/packet/af_packet.c:474 Code: c1 ee 03 f7 73 0c 80 3c 0e 00 0f 85 cb 01 00 00 48 8b 0b 89 c0 4c 8d 24 c1 48 b8 00 00 00 00 00 fc ff df 4c 89 e1 48 c1 e9 03 <80> 3c 01 00 0f 85 94 01 00 00 48 8d 7b 10 4d 8b 3c 24 48 b8 00 00 RSP: 0018:ffff88809f82f7b8 EFLAGS: 00010246 RAX: dffffc0000000000 RBX: ffff8880a45c7030 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 1ffff110148b8e06 RDI: ffff8880a45c703c RBP: ffff88809f82f7e8 R08: ffff888087aea200 R09: fffffbfff134ae50 R10: fffffbfff134ae4f R11: ffffffff89a5727f R12: 0000000000000000 R13: 0000000000000001 R14: ffff8880a45c6ac0 R15: 0000000000000000 FS: 00007fa04716f700(0000) GS:ffff8880ae900000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fa04716edb8 CR3: 0000000091eb4000 CR4: 00000000001406e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: packet_current_frame net/packet/af_packet.c:487 [inline] tpacket_snd net/packet/af_packet.c:2667 [inline] packet_sendmsg+0x590/0x6250 net/packet/af_packet.c:2975 sock_sendmsg_nosec net/socket.c:637 [inline] sock_sendmsg+0xd7/0x130 net/socket.c:657 ___sys_sendmsg+0x3e2/0x920 net/socket.c:2311 __sys_sendmmsg+0x1bf/0x4d0 net/socket.c:2413 __do_sys_sendmmsg net/socket.c:2442 [inline] __se_sys_sendmmsg net/socket.c:2439 [inline] __x64_sys_sendmmsg+0x9d/0x100 net/socket.c:2439 do_syscall_64+0xfd/0x6a0 arch/x86/entry/common.c:296 entry_SYSCALL_64_after_hwframe+0x49/0xbe Fixes: 69e3c75 ("net: TX_RING and packet mmap") Signed-off-by: Eric Dumazet <[email protected]> Reported-by: syzbot <[email protected]> Signed-off-by: David S.

This is to be expected bpf_get_stack call can only return a max of the input size but is free to return any negative error in the 32-bit register space. The C helper is returning an int so will use lower 32-bits. Lines 17 and 18 clear the top 32 bits with a left/right shift but use ARSH so we still have worst case min bound before line 19 of -2147483648. At this point the signed check 'r1 s< r8' meant to protect the addition on line 22 where dst reg is a map_value pointer may very well return true with a large negative number. Then the final line 22 will detect this as an invalid operation and fail the program. What we want to do is proceed only if r8 is positive non-error. So change 'r1 s< r8' to 'r1 s> r8' so that we jump if r8 is negative. Next we will throw an error because we access past the end of the map value. The map value size is 48 and sizeof(struct test_val) is 48 so we walk off the end of the map value on the second call to get bpf_get_stack(). Fix this by changing sizeof(struct test_val) to 24 by using 'sizeof(struct test_val) / 2'. After this everything passes as expected.

…assert libkernel: add `static_assert!` macro

For leaf dir, In most cases, there should be as many bestfree slots as the dir data blocks that can fit under i_size (except for [1]). Root cause is we don't examin the number bestfree slots, when the slots number less than dir data blocks, if we need to allocate new dir data block and update the bestfree array, we will use the dir block number as index to assign bestfree array, while we did not check the leaf buf boundary which may cause UAF or other memory access problem. This issue can also triggered with test cases xfs/473 from fstests. According to Dave Chinner & Darrick's suggestion, adding buffer verifier to detect this abnormal situation in time. Simplify the testcase for fstest xfs/554 [1] The error log is shown as follows: ================================================================== BUG: KASAN: use-after-free in xfs_dir2_leaf_addname+0x1995/0x1ac0 Write of size 2 at addr ffff88810168b000 by task touch/1552 CPU: 5 PID: 1552 Comm: touch Not tainted 6.0.0-rc3+ thesofproject#101 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x4d/0x66 print_report.cold+0xf6/0x691 kasan_report+0xa8/0x120 xfs_dir2_leaf_addname+0x1995/0x1ac0 xfs_dir_createname+0x58c/0x7f0 xfs_create+0x7af/0x1010 xfs_generic_create+0x270/0x5e0 path_openat+0x270b/0x3450 do_filp_open+0x1cf/0x2b0 do_sys_openat2+0x46b/0x7a0 do_sys_open+0xb7/0x130 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x63/0xcd RIP: 0033:0x7fe4d9e9312b Code: 25 00 00 41 00 3d 00 00 41 00 74 4b 64 8b 04 25 18 00 00 00 85 c0 75 67 44 89 e2 48 89 ee bf 9c ff ff ff b8 01 01 00 00 0f 05 <48> 3d 00 f0 ff ff 0f 87 91 00 00 00 48 8b 4c 24 28 64 48 33 0c 25 RSP: 002b:00007ffda4c16c20 EFLAGS: 00000246 ORIG_RAX: 0000000000000101 RAX: ffffffffffffffda RBX: 0000000000000001 RCX: 00007fe4d9e9312b RDX: 0000000000000941 RSI: 00007ffda4c17f33 RDI: 00000000ffffff9c RBP: 00007ffda4c17f33 R08: 0000000000000000 R09: 0000000000000000 R10: 00000000000001b6 R11: 0000000000000246 R12: 0000000000000941 R13: 00007fe4d9f631a4 R14: 00007ffda4c17f33 R15: 0000000000000000 </TASK> The buggy address belongs to the physical page: page:ffffea000405a2c0 refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x10168b flags: 0x2fffff80000000(node=0|zone=2|lastcpupid=0x1fffff) raw: 002fffff80000000 ffffea0004057788 ffffea000402dbc8 0000000000000000 raw: 0000000000000000 0000000000170000 00000000ffffffff 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff88810168af00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ffff88810168af80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >ffff88810168b000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ^ ffff88810168b080: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ffff88810168b100: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ================================================================== Disabling lock debugging due to kernel taint 00000000: 58 44 44 33 5b 53 35 c2 00 00 00 00 00 00 00 78 XDD3[S5........x XFS (sdb): Internal error xfs_dir2_data_use_free at line 1200 of file fs/xfs/libxfs/xfs_dir2_data.c.
