2022-02-15CDC-NCM: avoid overflow in sanity checkingOliver Neukum
A broken device may give an extreme offset like 0xFFF0 and a reasonable length for a fragment. In the sanity check as formulated now, this will create an integer overflow, defeating the sanity check. Both offset and offset + len need to be checked in such a manner that no overflow can occur. And those quantities should be unsigned.

2022-02-14tipc: fix wrong publisher node address in link publicationsJon Maloy
When a link comes up we add its presence to the name table to make it possible for users to subscribe for link up/down events. However, after a previous call signature change the binding is wrongly published with the peer node as publishing node, instead of the own node as it should be. This has the effect that the command 'tipc name table show' will list the link binding (service type 2) with node scope and a peer node as originator, something that obviously is impossible. We correct this bug here.

2022-02-14net: dsa: mv88e6xxx: flush switchdev FDB workqueue before removing VLANVladimir Oltean
mv88e6xxx is special among DSA drivers in that it requires the VTU to contain the VID of the FDB entry it modifies in mv88e6xxx_port_db_load_purge(), otherwise it will return -EOPNOTSUPP. Sometimes due to races this is not always satisfied even if external code does everything right (first deletes the FDB entries, then the VLAN), because DSA commits to hardware FDB entries asynchronously since commit c9eb3e0f8701 ("net: dsa: Add support for learning FDB through notification"). Therefore, the mv88e6xxx driver must close this race condition by itself, by asking DSA to flush the switchdev workqueue of any FDB deletions in progress, prior to exiting a VLAN.

2022-02-14ipv6: mcast: use rcu-safe version of ipv6_get_lladdr()Ignat Korchagin
Some time ago 8965779d2c0e ("ipv6,mcast: always hold idev->lock before mca_lock") switched ipv6_get_lladdr() to __ipv6_get_lladdr(), which is rcu-unsafe version. That was OK, because idev->lock was held for these codepaths. In 88e2ca308094 ("mld: convert ifmcaddr6 to RCU") these external locks were removed, so we probably need to restore the original rcu-safe call. Otherwise, we occasionally get a machine crashed/stalled with the following in dmesg: [ 3405.966610][T230589] general protection fault, probably for non-canonical address 0xdead00000000008c: 0000 [#1] SMP NOPTI [ 3405.982083][T230589] CPU: 44 PID: 230589 Comm: kworker/44:3 Tainted: G O 5.15.19-cloudflare-2022.2.1 #1 [ 3405.998061][T230589] Hardware name: SUPA-COOL-SERV [ 3406.009552][T230589] Workqueue: mld mld_ifc_work [ 3406.017224][T230589] RIP: 0010:__ipv6_get_lladdr+0x34/0x60 [ 3406.025780][T230589] Code: 57 10 48 83 c7 08 48 89 e5 48 39 d7 74 3e 48 8d 82 38 ff ff ff eb 13 48 8b 90 d0 00 00 00 48 8d 82 38 ff ff ff 48 39 d7 74 22 <66> 83 78 32 20 77 1b 75 e4 89 ca 23 50 2c 75 dd 48 8b 50 08 48 8b [ 3406.055748][T230589] RSP: 0018:ffff94e4b3fc3d10 EFLAGS: 00010202 [ 3406.065617][T230589] RAX: dead00000000005a RBX: ffff94e4b3fc3d30 RCX: 0000000000000040 [ 3406.077477][T230589] RDX: dead000000000122 RSI: ffff94e4b3fc3d30 RDI: ffff8c3a31431008 [ 3406.089389][T230589] RBP: ffff94e4b3fc3d10 R08: 0000000000000000 R09: 0000000000000000 [ 3406.101445][T230589] R10: ffff8c3a31430000 R11: 000000000000000b R12: ffff8c2c37887100 [ 3406.113553][T230589] R13: ffff8c3a39537000 R14: 00000000000005dc R15: ffff8c3a31431000 [ 3406.125730][T230589] FS: 0000000000000000(0000) GS:ffff8c3b9fc80000(0000) knlGS:0000000000000000 [ 3406.138992][T230589] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 3406.149895][T230589] CR2: 00007f0dfea1db60 CR3: 000000387b5f2000 CR4: 0000000000350ee0 [ 3406.162421][T230589] Call Trace: [ 3406.170235][T230589] <TASK> [ 3406.177736][T230589] mld_newpack+0xfe/0x1a0 [ 3406.186686][T230589] add_grhead+0x87/0xa0 [ 3406.195498][T230589] add_grec+0x485/0x4e0 [ 3406.204310][T230589] ? newidle_balance+0x126/0x3f0 [ 3406.214024][T230589] mld_ifc_work+0x15d/0x450 [ 3406.223279][T230589] process_one_work+0x1e6/0x380 [ 3406.232982][T230589] worker_thread+0x50/0x3a0 [ 3406.242371][T230589] ? rescuer_thread+0x360/0x360 [ 3406.252175][T230589] kthread+0x127/0x150 [ 3406.261197][T230589] ? set_kthread_struct+0x40/0x40 [ 3406.271287][T230589] ret_from_fork+0x22/0x30 [ 3406.280812][T230589] </TASK> [ 3406.288937][T230589] Modules linked in: ...

2022-02-14parisc: Fix some apparent put_user() failuresHelge Deller
After commit 4b9d2a731c3d ("parisc: Switch user access functions to signal errors in r29 instead of r8") bash suddenly started to report those warnings after login: -bash: cannot set terminal process group (-1): Bad file descriptor -bash: no job control in this shell It turned out, that a function call inside a put_user(), e.g.: put_user(vt_do_kdgkbmode(console), (int __user *)arg); clobbered the error register (r29) and thus the put_user() call itself seem to have failed. Rearrange the C-code to pre-calculate the intermediate value and then do the put_user(). Additionally prefer the "+" constraint on pu_err and gu_err registers to tell the compiler that those operands are both read and written by the assembly instruction.

2022-02-14ice: enable parsing IPSEC SPI headers for RSSJesse Brandeburg
The COMMS package can enable the hardware parser to recognize IPSEC frames with ESP header and SPI identifier. If this package is available and configured for loading in /lib/firmware, then the driver will succeed in enabling this protocol type for RSS. This in turn allows the hardware to hash over the SPI and use it to pick a consistent receive queue for the same secure flow. Without this all traffic is steered to the same queue for multiple traffic threads from the same IP address. For that reason this is marked as a fix, as the driver supports the model, but it wasn't enabled. If the package is not available, adding this type will fail, but the failure is ignored on purpose as it has no negative affect.
