2017-02-03be2net: get rid of custom busy poll codeEric Dumazet
Compared to custom busy_poll, the generic NAPI one is better, since it allows to use GRO, and it removes a lot of code and extra locked operations in fast path.

2017-02-03vxlan: support fdb and learning in COLLECT_METADATA modeRoopa Prabhu
Vxlan COLLECT_METADATA mode today solves the per-vni netdev scalability problem in l3 networks. It expects all forwarding information to be present in dst_metadata. This patch series enhances collect metadata mode to include the case where only vni is present in dst_metadata, and the vxlan driver can then use the rest of the forwarding information datbase to make forwarding decisions. There is no change to default COLLECT_METADATA behaviour. These changes only apply to COLLECT_METADATA when used with the bridging use-case with a special dst_metadata tunnel info flag (eg: where vxlan device is part of a bridge). For all this to work, the vxlan driver will need to now support a single fdb table hashed by mac + vni. This series essentially makes this happen. use-case and workflow: vxlan collect metadata device participates in bridging vlan to vn-segments. Bridge driver above the vxlan device, sends the vni corresponding to the vlan in the dst_metadata. vxlan driver will lookup forwarding database with (mac + vni) for the required remote destination information to forward the packet. Changes introduced by this patch: - allow learning and forwarding database state in vxlan netdev in COLLECT_METADATA mode. Current behaviour is not changed by default. tunnel info flag IP_TUNNEL_INFO_BRIDGE is used to support the new bridge friendly mode. - A single fdb table hashed by (mac, vni) to allow fdb entries with multiple vnis in the same fdb table - rx path already has the vni - tx path expects a vni in the packet with dst_metadata - prior to this series, fdb remote_dsts carried remote vni and the vxlan device carrying the fdb table represented the source vni. With the vxlan device now representing multiple vnis, this patch adds a src vni attribute to the fdb entry. The remote vni already uses NDA_VNI attribute. This patch introduces NDA_SRC_VNI netlink attribute to represent the src vni in a multi vni fdb table. iproute2 example (patched and pruned iproute2 output to just show relevant fdb entries): example shows same host mac learnt on two vni's. before (netdev per vni): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan1000 dst 12.0.0.8 self after this patch with collect metadata in bridged mode (single netdev): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan0 src_vni 1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan0 src_vni 1000 dst 12.0.0.8 self Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: David S.

2017-02-03dm crypt: replace RCU read-side section with rwsemOndrej Kozina
The lockdep splat below hints at a bug in RCU usage in dm-crypt that was introduced with commit c538f6ec9f56 ("dm crypt: add ability to use keys from the kernel key retention service"). The kernel keyring function user_key_payload() is in fact a wrapper for rcu_dereference_protected() which must not be called with only rcu_read_lock() section mark. Unfortunately the kernel keyring subsystem doesn't currently provide an interface that allows the use of an RCU read-side section. So for now we must drop RCU in favour of rwsem until a proper function is made available in the kernel keyring subsystem. =============================== [ INFO: suspicious RCU usage. ] 4.10.0-rc5 #2 Not tainted ------------------------------- ./include/keys/user-type.h:53 suspicious rcu_dereference_protected() usage! other info that might help us debug this: rcu_scheduler_active = 2, debug_locks = 1 2 locks held by cryptsetup/6464: #0: (&md->type_lock){+.+.+.}, at: [<ffffffffa02472a2>] dm_lock_md_type+0x12/0x20 [dm_mod] #1: (rcu_read_lock){......}, at: [<ffffffffa02822f8>] crypt_set_key+0x1d8/0x4b0 [dm_crypt] stack backtrace: CPU: 1 PID: 6464 Comm: cryptsetup Not tainted 4.10.0-rc5 #2 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.9.1-1.fc24 04/01/2014 Call Trace: dump_stack+0x67/0x92 lockdep_rcu_suspicious+0xc5/0x100 crypt_set_key+0x351/0x4b0 [dm_crypt] ? crypt_set_key+0x1d8/0x4b0 [dm_crypt] crypt_ctr+0x341/0xa53 [dm_crypt] dm_table_add_target+0x147/0x330 [dm_mod] table_load+0x111/0x350 [dm_mod] ? retrieve_status+0x1c0/0x1c0 [dm_mod] ctl_ioctl+0x1f5/0x510 [dm_mod] dm_ctl_ioctl+0xe/0x20 [dm_mod] do_vfs_ioctl+0x8e/0x690 ? ____fput+0x9/0x10 ? task_work_run+0x7e/0xa0 ? trace_hardirqs_on_caller+0x122/0x1b0 SyS_ioctl+0x3c/0x70 entry_SYSCALL_64_fastpath+0x18/0xad RIP: 0033:0x7f392c9a4ec7 RSP: 002b:00007ffef6383378 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00007ffef63830a0 RCX: 00007f392c9a4ec7 RDX: 000000000124fcc0 RSI: 00000000c138fd09 RDI: 0000000000000005 RBP: 00007ffef6383090 R08: 00000000ffffffff R09: 00000000012482b0 R10: 2a28205d34383336 R11: 0000000000000246 R12: 00007f392d803a08 R13: 00007ffef63831e0 R14: 0000000000000000 R15: 00007f392d803a0b Fixes: c538f6ec9f56 ("dm crypt: add ability to use keys from the kernel key retention service") Reported-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Ondrej Kozina <okozina@redhat.com> Reviewed-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>

2017-02-03iwlwifi: mvm: synchronize firmware DMA paging memorySara Sharon
When driver needs to access the contents of a streaming DMA buffer without unmapping it it should call dma_sync_single_for_cpu(). Once the call has been made, the CPU "owns" the DMA buffer and can work with it as needed. Before the device accesses the buffer, however, ownership should be transferred back to it with dma_sync_single_for_device(). Both calls weren't performed by the driver, resulting with odd paging errors on some platforms. Fix it.

INIT complete will now follow the NVM access command, without phy DB calls before. * Paging command is sent earlier in the flow before NVM access to enable a complete load of FW. * caution must be care when restart is called since we may have not completed init flow even though we are in RT firmware.

2017-02-02i40e: add interrupt rate limit verbosityAlan Brady
Due to the resolution of the register controlling interrupt rate limiting, setting certain values for the interrupt rate limit make it appear as though the limiting is not completely accurate. The problem is that the interrupt rate limit is getting rounded down to the nearest multiple of 4. This patch fixes the problem by adding some feedback to the user as to the actual interrupt rate limit being used when it differs from the requested limit. Without this patch setting interrupt rate limits may appear to behave inaccurately.

2017-02-02i40e: refactor macro INTRL_USEC_TO_REGAlan Brady
This patch refactors the macro INTRL_USEC_TO_REG into a static inline function and fixes a couple subtle bugs caused by the macro. This patch fixes a bug which was caused by passing a bad register value to the firmware. If enabling interrupt rate limiting, a non-zero value for the rate limit must be used. Otherwise the firmware sets the interrupt rate limit to the maximum value. Due to the limited resolution of the register, attempting to set a value of 1, 2, or 3 would be rounded down to 0 and limiting was left enabled, causing unexpected behavior. This patch also fixes a possible bug in which using the macro itself can introduce unintended side-affects because the macro argument is used more than once in the macro definition (e.g. a variable post-increment argument would perform a double increment on the variable). Without this patch, attempting to set interrupt rate limits of 1, 2, or 3 results in unexpected behavior and future use of this macro could cause subtle bugs.

2017-02-02i40e: remove unnecessary __packedTushar Dave
'struct i40e_dma_mem' defined with 'packed' directive causing kernel unaligned errors on sparc. e.g. i40e: Intel(R) Ethernet Connection XL710 Network Driver - version 1.6.16-k i40e: Copyright (c) 2013 - 2014 Intel Corporation. Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 i40e 0000:03:00.0: fw 5.1.40981 api 1.5 nvm 5.04 0x80002548 0.0.0 This can be fixed with get_unaligned/put_unaligned(). However no reference in driver shows that 'struct i40e_dma_mem' directly shoved into NIC hardware. But instead fields of the struct are being read and used for hardware. Therefore, __packed is unnecessary for 'struct i40e_dma_mem'. In addition, although 'struct i40e_virt_mem' doesn't cause any unaligned access, keeping it packed is unnecessary as well because of aforementioned reason. This change make 'struct i40e_dma_mem' and 'struct i40e_virt_mem' unpacked.

2017-02-02i40e: Deprecating unused macroBimmy Pujari
I40E_MAC_X710 was supposed to be for 10G and I40E_MAC_XL710 was supposed to be for 40G. But function i40e_is_mac_710 sets I40E_MAC_XL710 for all device IDS, I40E_MAC_X710 is not used at all. As there is nothing to compare there is no need for this function. Thus deprecating this extra macro and removing this function entirely and replacing it with a direct check.

2017-02-02i40e: when adding or removing MAC filters, correctly handle VLANsJacob Keller
Instead of using i40e_add_filter or i40e_del_filter directly, when adding a MAC address, we should normally be using i40e_add_mac_filter or i40e_del_mac_filter. These functions correctly handle the various cases of VLAN mode or PVID settings. This ensures consistency and avoids the issues that can occur with the recent addition of a WARN_ON() in i40e_sync_vsi_filters.

2017-02-02i40e: rename i40e_put_mac_in_vlan and i40e_del_mac_all_vlanJacob Keller
These functions purpose is to add a new MAC filter correctly, whether we're using VLANs or not. Their goal is to ensure that all active VLANs get the new MAC filter. Rename them so that their intent is clear. They function correctly regardless of whether we have any active VLANs or only have I40E_VLAN_ANY filters. The new names convey how they function in a more clear manner.

2017-02-02i40e: no need to check is_vsi_in_vlan before calling i40e_del_mac_all_vlanJacob Keller
This function won't be appreciably slower when in VLAN mode, so there is no real reason to not just call it directly. In either case, we still must search the full table for a MAC/VLAN pair. We do get to stop searching a tiny bit early in the case of knowing we are not in VLAN mode, but this is a minor savings and we can avoid the code complexity by not having to worry about the check.

Fold the check for determining when to call i40e_put_mac_in_vlan directly into the function so that we don't need to decide which function to use ahead of time. This allows us to just call i40e_put_mac_in_vlan directly without having to check ahead of time.

2017-02-02i40e: don't allow i40e_vsi_(add|kill)_vlan to operate when VID<1Jacob Keller
Now that we have the separate i40e_(add|rm)_vlan_all_mac functions, we should not be using the i40e_vsi_kill_vlan or i40e_vsi_add_vlan functions when PVID is set or when VID is less than 1. This allows us to remove some checks in i40e_vsi_add_vlan and ensures that callers which need to handle VID=0 or VID=-1 don't accidentally invoke the VLAN mode handling used to convert filters when entering VLAN mode. We also update the functions to take u16 instead of s16 as well since they no longer expect to be called with VID=I40E_VLAN_ANY.
