* r8152: fix the list rx_done may be used without initializationhayeswang2017-03-211-0/+1
| | | | | | | | | | | | | | The list rx_done would be initialized when the linking on occurs. Therefore, if a napi is scheduled without any linking on before, the following kernel panic would happen.

* tcp: tcp_get_info() should read tcp_time_stamp laterEric Dumazet2017-03-161-1/+2
| | | | | | | | | | | | | | | | Commit b369e7fd41f7 ("tcp: make TCP_INFO more consistent") moved lock_sock_fast() earlier in tcp_get_info() This has the minor effect that jiffies value being sampled at the beginning of tcp_get_info() is more likely to be off by one, and we report big tcpi_last_data_sent values (like 0xFFFFFFFF). Since we lock the socket, fetching tcp_time_stamp right before doing the jiffies_to_msecs() calls is enough to remove these wrong values.

| | | | | | | | | | | When device is being setup on boot, there is a small race where network device callback is registered, but the netvsc_device pointer is not set yet.

| | | | | | | | | | | | | | Andrei reported a false alarm of lockdep at net/bridge/br_fdb.c:109, this is because in Andrei's case, a spin_bug() was already triggered before this, therefore the debug_locks is turned off, lockdep_is_held() is no longer accurate after that. We should use lockdep_assert_held_once() instead of lockdep_is_held() to respect debug_locks.

* rxrpc: Ignore BUSY packets on old callsDavid Howells2017-03-161-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we receive a BUSY packet for a call we think we've just completed, the packet is handed off to the connection processor to deal with - but the connection processor doesn't expect a BUSY packet and so flags a protocol error. Fix this by simply ignoring the BUSY packet for the moment. The symptom of this may appear as a system call failing with EPROTO. This may be triggered by pressing ctrl-C under some circumstances. This comes about we abort calls due to interruption by a signal (which we shouldn't do, but that's going to be a large fix and mostly in fs/afs/). What happens is that we abort the call and may also abort follow up calls too (this needs offloading somehoe). So we see a transmission of something like the following sequence of packets: DATA for call N ABORT call N DATA for call N+1 ABORT call N+1 in very quick succession on the same channel. However, the peer may have deferred the processing of the ABORT from the call N to a background thread and thus sees the DATA message from the call N+1 coming in before it has cleared the channel. Thus it sends a BUSY packet[*]. [*] Note that some implementations (OpenAFS, for example) mark the BUSY packet with one plus the callNumber of the call prior to call N. Ordinarily, this would be call N, but there's no requirement for the calls on a channel to be numbered strictly sequentially (the number is required to increase). This is wrong and means that the callNumber in the BUSY packet should be ignored (it really ought to be N+1 since that's what it's in response to).

* net/mlx4_core: Avoid delays during VF driver device shutdownJack Morgenstein2017-03-163-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Hypervisors detach VFs from VMs by instantly causing an FLR event to be generated for a VF. In the mlx4 case, this will cause that VF's comm channel to be disabled before the VM has an opportunity to invoke the VF device's "shutdown" method. For such Hypervisors, there is a race condition between the VF's shutdown method and its internal-error detection/reset thread. The internal-error detection/reset thread (which runs every 5 seconds) also detects a disabled comm channel. If the internal-error detection/reset flow wins the race, we still get delays (while that flow tries repeatedly to detect comm-channel recovery). The cited commit fixed the command timeout problem when the internal-error detection/reset flow loses the race. This commit avoids the unneeded delays when the internal-error detection/reset flow wins.

The latter often leads to problems when networks are incorrectly configured and don't use a common MTU. The sender could for example fragment a 1271 byte frame (plus external ethernet header (14) and batadv unicast header (10)) to fit in a 1280 bytes large MTU of the underlying link (max. 1294 byte frames). This would create a 1294 bytes large frame (fragment 2) and a 55 bytes large frame (fragment 1). The extra 54 bytes are the fragment header (20) added to each fragment and the external ethernet header (14) for the second fragment. Let us assume that the next hop is then not able to transport 1294 bytes to its next hop. The 1294 byte large frame will be dropped but the 55 bytes large fragment will still be forwarded to its destination. Or let us assume that the underlying hardware requires that each frame has a minimum size (e.g. 60 bytes). Then it will pad the 55 bytes frame to 60 bytes. The receiver of the 60 bytes frame will no longer be able to correctly assemble the two frames together because it is not aware that 5 bytes of the 60 bytes frame are padding and don't belong to the reassembled frame. This can partly be avoided by splitting frames more equally. In this example, the 675 and 674 bytes large fragment frames could both potentially reach its destination without being too large or too small.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer hardware does not provide a cumulative payload length when multiple descriptors are needed to handle the data. Once the MTU increases beyond the size that can be handled by a single descriptor, the SKB does not get built properly by the driver. The driver will now calculate the size of the data buffers used by the hardware. The first buffer of the first descriptor is for packet headers or packet headers and data when the headers can't be split. Subsequent descriptors in a multi-descriptor chain will not use the first buffer. The second buffer is used by all the descriptors in the chain for payload data. Based on whether the driver is processing the first, intermediate, or last descriptor it can calculate the buffer usage and build the SKB properly. Tested and verified on both old and new hardware.

For example: u32 *dest = &regs->data[priv->dreg]; 1. *dest = 0; *(u16 *) dest = val_u16; 2. *dest = val_u16; For method 1, the u16 value will be stored like this, either in big-endian or little-endian system: 0 15 31 +-+-+-+-+-+-+-+-+-+-+-+-+ | Value | 0 | +-+-+-+-+-+-+-+-+-+-+-+-+ For method 2, in little-endian system, the u16 value will be the same as listed above. But in big-endian system, the u16 value will be stored like this: 0 15 31 +-+-+-+-+-+-+-+-+-+-+-+-+ | 0 | Value | +-+-+-+-+-+-+-+-+-+-+-+-+ So later we use "memcmp(&regs->data[priv->sreg], data, 2);" to do compare in nft_cmp, nft_lookup expr ..., method 2 will get the wrong result in big-endian system, as 0~15 bits will always be zero. For the similar reason, when loading an u16 value from the u32 data register, we should use "*(u16 *) sreg;" instead of "(u16)*sreg;", the 2nd method will get the wrong value in the big-endian system. So introduce some wrapper functions to store/load an u8 or u16 integer to/from the u32 data register, and use them in the right place.

This is incorrect, for example, the tcp port number is only 16 bits. So when we use the nft_payload expr to get the tcp dport and store it to dreg, the dport will be stored at 0~15 bits, and 16~31 bits will be padded with zero. So the reg->data[dreg] will be looked like as below: 0 15 31 +-+-+-+-+-+-+-+-+-+-+-+-+ | tcp dport | 0 | +-+-+-+-+-+-+-+-+-+-+-+-+ But for these big-endian systems, if we treate this register as a u32 integer, the element key will be larger than 65535, so the following lookup in bitmap set will cause out of bound access. Another issue is that if we add element with comments in bitmap set(although the comments will be ignored eventually), the element will vanish strangely. Because we treate the element key as a u32 integer, so the comments will become the part of the element key, then the element key will also be larger than 65535 and out of bound access will happen: # nft add element t s { 1 comment test } Since set->klen is 1 or 2, it's fine to treate the element key as a u8 or u16 integer.

| * | netfilter: nf_tables: set pktinfo->thoff at AH header if foundPablo Neira Ayuso2017-03-081-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Phil Sutter reports that IPv6 AH header matching is broken. From userspace, nft generates bytecode that expects to find the AH header at NFT_PAYLOAD_TRANSPORT_HEADER both for IPv4 and IPv6. However, pktinfo->thoff is set to the inner header after the AH header in IPv6, while in IPv4 pktinfo->thoff points to the AH header indeed. This behaviour is inconsistent. This patch fixes this problem by updating ipv6_find_hdr() to get the IP6_FH_F_AUTH flag so this function stops at the AH header, so both IPv4 and IPv6 pktinfo->thoff point to the AH header. This is also inconsistent when trying to match encapsulated headers: 1) A packet that looks like IPv4 + AH + TCP dport 22 will *not* match. 2) A packet that looks like IPv6 + AH + TCP dport 22 will match.

At present in sctp_manip_pkt(), no matter whether the packet is ICMP or not, it always calculates SCTP packet checksum. However, not only the calculation of checksum is unnecessary for ICMP, but also it causes another fatal issue that ICMP packet is dropped. The header size of SCTP is used to identify whether the writeable length of skb is bigger than skb->len through skb_make_writable() in sctp_manip_pkt(). But when it deals with ICMP packet, skb_make_writable() directly returns false as the writeable length of skb is bigger than skb->len. Subsequently ICMP is dropped. Now we correct this misbahavior. When sctp_manip_pkt() handles ICMP packet, 8 bytes rather than the whole SCTP header size is used to check if writeable length of skb is overflowed. Meanwhile, as it's meaningless to calculate checksum when packet is ICMP, the computation of checksum is ignored as well.

As conntrack doesn't track packets without complete l4 header, only the first fragment is tracked. Because applying nat to first packet but not the rest makes no sense this also turns off tracking of all fragments.

Without this patch, a GEN2 Linux guest on Hyper-V will not boot 4.11 successfully with virtual DVD ROM device. What happens is that the SCSI scan process falls back to doing sequential probing by INQUIRY. But the storvsc driver has a previous workaround that masks/blocks all errors reports from INQUIRY (or MODE_SENSE) commands. This workaround causes the scan to then populate a full set of bogus LUN's on the target and then sends kernel spinning off into a death spiral doing block reads on the non-existent LUNs. By setting the correct blacklist flags, the target with the DVD device is scanned with REPORTLUN and that works correctly. Patch needs to go in current 4.11, it is safe but not necessary in older kernels. Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com> Reviewed-by: K. Y.

This was done to allow tape devices being used for back up from being removed. Why was this done ? When there was non-responding device on the fabric, the error escalation policy would escalate to the reset handler. When the reset handler was called, it would reset the adapter, dropping link, thus logging out and terminating all i/o's - on any target. If there was a tape device on the same adapter that wasn't in error, it would kill the tape i/o's, effectively killing the tape device state. With the reset point removed, the adapter reset avoided the fabric logout, allowing the other devices to continue to operate unaffected. A hack - yes. Hint: we really need a transport I_T nexus reset callback added to the eh process (in between the SCSI target reset and hba reset points), so a fc logout could occur to the one bad target only and stop the error escalation process. This patch commonizes the approach so it can be used for sli3 and sli4 adapters, but mandates the admin, via module parameter, specifically identify which adapters the resets are to be removed for. Additionally, bus_reset, which sends Target Reset TMFs to all targets, is also removed from the template as it too has the same effect as the adapter reset.
