2019-07-30sctp: clean up __sctp_connectXin Long1-136/+73
__sctp_connect is doing quit similar things as sctp_sendmsg_new_asoc. To factor out common functions, this patch is to clean up their code to make them look more similar: 1. create the asoc and add a peer with the 1st addr. 2. add peers with the other addrs into this asoc one by one. while at it, also remove the unused 'addrcnt'.

2019-07-30sctp: check addr_size with sa_family_t size in __sctp_setsockopt_connectxXin Long1-1/+2
Now __sctp_connect() is called by __sctp_setsockopt_connectx() and sctp_inet_connect(), the latter has done addr_size check with size of sa_family_t. In the next patch to clean up __sctp_connect(), we will remove addr_size check with size of sa_family_t from __sctp_connect() for the 1st address. So before doing that, __sctp_setsockopt_connectx() should do this check first, as sctp_inet_connect() does. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.

2019-07-30sctp: only copy the available addr data in sctp_transport_initXin Long1-1/+1
'addr' passed to sctp_transport_init is not always a whole size of union sctp_addr, like the path: sctp_sendmsg() -> sctp_sendmsg_new_asoc() -> sctp_assoc_add_peer() -> sctp_transport_new() -> sctp_transport_init() In the next patches, we will also pass the address length of data only to sctp_assoc_add_peer(). So sctp_transport_init() should copy the only available data from addr to peer->ipaddr, instead of 'peer->ipaddr = *addr' which may cause slab-out-of-bounds.

2019-07-30rxrpc: Fix -Wframe-larger-than= warnings from on-stack cryptoDavid Howells4-20/+96
rxkad sometimes triggers a warning about oversized stack frames when building with clang for a 32-bit architecture: net/rxrpc/rxkad.c:243:12: error: stack frame size of 1088 bytes in function 'rxkad_secure_packet' [-Werror,-Wframe-larger-than=] net/rxrpc/rxkad.c:501:12: error: stack frame size of 1088 bytes in function 'rxkad_verify_packet' [-Werror,-Wframe-larger-than=] The problem is the combination of SYNC_SKCIPHER_REQUEST_ON_STACK() in rxkad_verify_packet()/rxkad_secure_packet() with the relatively large scatterlist in rxkad_verify_packet_1()/rxkad_secure_packet_encrypt(). The warning does not show up when using gcc, which does not inline the functions as aggressively, but the problem is still the same. Allocate the cipher buffers from the slab instead, caching the allocated packet crypto request memory used for DATA packet crypto in the rxrpc_call struct.

2019-07-29bnxt_en: Add TPA ID mapping logic for 57500 chips.Michael Chan2-2/+53
The new TPA feature on 57500 supports a larger number of concurrent TPAs (up to 1024) divided among the functions. We need to add some logic to map the hardware TPA ID to a software index that keeps track of each TPA in progress. A 1:1 direct mapping without translation would be too wasteful as we would have to allocate 1024 TPA structures for each RX ring on each PCI function.

The aggregation completions are not completed at the TPA_END completion on 57500 chips so we need to keep track of them. The array is only allocated on the new chips when required. An agg_count field is also added to keep track of the number of these completions. The maximum concurrent TPA is now discovered from firmware instead of the hardcoded 64.

Refactor the TPA logic slightly, so that the code can be more easily extended to support TPA on the new 57500 chips. In particular, the logic to get the next aggregation completion is refactored into a new function bnxt_get_agg() so that this operation is made more generalized. This operation will be different on the new chip in TPA mode. The logic to recycle the aggregation buffers has a new start index parameter added for the same purpose.

Commit 60649d4e0af ("can: remove obsolete empty ioctl() handler") replaced the almost empty can_ioctl() function with sock_no_ioctl() which always returns -EOPNOTSUPP. Even though we don't have any ioctl() functions on socket/network layer we need to return -ENOIOCTLCMD to be able to forward ioctl commands like SIOCGIFINDEX to the network driver layer.

2019-07-29net: dsa: mv88e6xxx: avoid some redundant vtu load/purge operationsRasmus Villemoes1-1/+3
We have an ERPS (Ethernet Ring Protection Switching) setup involving mv88e6250 switches which we're in the process of switching to a BSP based on the mainline driver. Breaking any link in the ring works as expected, with the ring reconfiguring itself quickly and traffic continuing with almost no noticable drops. However, when plugging back the cable, we see 5+ second stalls. This has been tracked down to the userspace application in charge of the protocol missing a few CCM messages on the good link (the one that was not unplugged), causing it to broadcast a "signal fail". That message eventually reaches its link partner, which responds by blocking the port. Meanwhile, the first node has continued to block the port with the just plugged-in cable, breaking the network. And the reason for those missing CCM messages has in turn been tracked down to the VTU apparently being too busy servicing load/purge operations that the normal lookups are delayed. Initial state, the link between C and D is blocked in software. _____________________ / \ | | A ----- B ----- C *---- D Unplug the cable between C and D. _____________________ / \ | | A ----- B ----- C * * D Reestablish the link between C and D. _____________________ / \ | | A ----- B ----- C *---- D Somehow, enough VTU/ATU operations happen inside C that prevents the application from receving the CCM messages from B in a timely manner, so a Signal Fail message is sent by C. When B receives that, it responds by blocking its port. _____________________ / \ | | A ----- B *---* C *---- D Very shortly after this, the signal fail condition clears on the BC link (some CCM messages finally make it through), so C unblocks the port. However, a guard timer inside B prevents it from removing the blocking before 5 seconds have elapsed. It is not unlikely that our userspace ERPS implementation could be smarter and/or is simply buggy. However, this patch fixes the symptoms we see, and is a small optimization that should not break anything (knock wood). The idea is simply to avoid doing an VTU load of an entry identical to the one already present. To do that, we need to know whether mv88e6xxx_vtu_get() actually found an existing entry, or has just prepared a struct mv88e6xxx_vtu_entry for us to load. To that end, let vlan->valid be an output parameter. The other two callers of mv88e6xxx_vtu_get() are not affected by this patch since they pass new=false.

There was a previous attempt to use xmit_more, but the change had to be reverted because under load sometimes a transmit timeout occurred [0]. Maybe this was caused by a missing memory barrier, the new attempt keeps the memory barrier before the call to netif_stop_queue like it is used by the driver as of today.

2019-07-29net: hns3: change GFP flag during lock periodYufeng Mo1-1/+1
When allocating memory, the GFP_KERNEL cannot be used during the spin_lock period. This is because it may cause scheduling when holding spin_lock. This patch changes GFP flag to GFP_ATOMIC in this case.

2019-07-29net: hns3: remove upgrade reset level when reset failHuazhong Tan1-20/+8
Currently, hclge_reset_err_handle() will assert a global reset when the failing count is smaller than MAX_RESET_FAIL_CNT, which will affect other running functions. So this patch removes this upgrading, and uses re-scheduling reset task to do it.
