On older windows hosts the net_device instance is returned to the caller of rndis_filter_device_add() without having the presence bit set first. This would cause any subsequent calls to network device operations (e.g. MTU change, channel change) to fail after the device is detached once, returning -ENODEV. Instead of returning the device instabce, we take the exit path where we call netif_device_attach() Fixes: 7b2ee50c ("hv_netvsc: common detach logic") Signed-off-by:

Since commit 29a5dcae ("nfp: flower: offload phys port MTU change") we take encapsulation headroom into account when calculating the max allowed MTU. This is unnecessary as the max MTU advertised by firmware should have already accounted for encap headroom. Subtracting headroom twice brings the max MTU below what's necessary for some deployments.

When we get link properties through netlink interface with tipc_nl_node_get_link(), we don't validate TIPC_NLA_LINK_NAME attribute at all, instead we directly use it.

Since commit a92a0849 "r8169: improve runtime pm in general and suspend unused ports" interfaces w/o link are runtime-suspended after 10s. On systems where drivers take longer to load this can lead to the situation that the interface is runtime-suspended already when it's initially brought up. This shouldn't be a problem because rtl_open() resumes MAC/PHY. However with at least one chip version the interface doesn't properly come up, as reported here: https://bugzilla.kernel.org/show_bug.cgi?id=199549 The vendor driver uses a delay to give certain chip versions some time to resume before starting the PHY configuration. So let's do the same. I don't know which chip versions may be affected, therefore apply this delay always. This patch was reported to fix the issue for RTL8168h. I was able to reproduce the issue on an Asus H310I-Plus which also uses a RTL8168h. Also in my case the patch fixed the issue. Reported-by:

Commit d50f4630 ("arm: dts: Remove p1010-flexcan compatible from imx series dts") removed the fallback compatible "fsl,p1010-flexcan" from the imx device trees. As the flexcan cores on i.MX25, i.MX35 and i.MX53 are identical, introduce the first as fallback for the two latter ones.

In commit 88462d2a ("can: flexcan: Remodel FlexCAN register r/w APIs for big endian FlexCAN controllers.") the following logic was implemented: if the dt property "big-endian" is given or the device is compatible to "fsl,p1010-flexcan": use big-endian mode; else use little-endian mode; This relies on commit d50f4630 ("arm: dts: Remove p1010-flexcan compatible from imx series dts") which was applied a few commits later. Without this commit (or an old device tree used for booting a new kernel) the flexcan devices on i.MX25, i.MX28, i.MX35 and i.MX53 match the 'the device is compatible to "fsl,p1010-flexcan"' test and so are switched erroneously to big endian mode. Instead of the check above put a quirk in devtype data and rely on of_match_device yielding the most compatible match Fixes: 88462d2a ("can: flexcan: Remodel FlexCAN register r/w APIs for big endian FlexCAN controllers.")

bus-off is usually caused by hardware malfunction or configuration error (baud rate mismatch) and causes a complete loss of communication. Increase the "bus-off" message's severity from netdev_dbg() to netdev_info() to make it visible to the user. A can interface going into bus-off is similar in severity to ethernet's "Link is Down" message, which is also printed at info level. It is debatable whether the the "restarted" message should also be changed to netdev_info() to make the interface state changes comprehensible from the kernel log. I have chosen to keep the "restarted" message at dbg for now as the "bus-off" message should be enough for the user to notice and investigate the problem. Signed-off-by:

Now sctp only delays the authentication for the normal cookie-echo chunk by setting chunk->auth_chunk in sctp_endpoint_bh_rcv(). But for the duplicated one with auth, in sctp_assoc_bh_rcv(), it does authentication first based on the old asoc, which will definitely fail due to the different auth info in the old asoc. The duplicated cookie-echo chunk will create a new asoc with the auth info from this chunk, and the authentication should also be done with the new asoc's auth info for all of the collision 'A', 'B' and 'D'. Otherwise, the duplicated cookie-echo chunk with auth will never pass the authentication and create the new connection. This issue exists since very beginning, and this fix is to make sctp_assoc_bh_rcv() follow the way sctp_endpoint_bh_rcv() does for the normal cookie-echo chunk to delay the authentication. While at it, remove the unused params from sctp_sf_authenticate() and define sctp_auth_chunk_verify() used for all the places that do the delayed authentication. v1->v2: fix the typo in changelog as Marcelo noticed.

Fix issue where nixge_get_nvmem_address() returns a non-NULL return value on a failed nvmem_cell_get() that causes an invalid access when error value encoded in pointer is dereferenced. Furthermore ensure that buffer allocated by nvmem_cell_read() actually gets kfreed() if the function succeeds.

Johan Hedberg says: ==================== pull request: bluetooth 2018-05-07 Here are a few more Bluetooth fixes for the 4.17 kernel, all for the btusb driver. Two relate to the needs_reset_resume table, and one is a revert of a patch for Atheros 1525/QCA6174 which caused a regression for some people. ==================== Signed-off-by:

In an SFP EEPROM values can be read to get information about a given SFP module. One of those is the bitrate, which can be determined using a nominal bitrate in addition with min and max values (in %). The SFP code currently compute both BR,min and BR,max values thanks to this nominal and min,max values. This patch fixes the BR,min computation as the min value should be subtracted to the nominal one, not added. Fixes: 9962acf7 ("sfp: add support for 1000Base-PX and 1000Base-BX10") Signed-off-by:

Currently, skb->len and skb->data_len are set to the page size, not the packet size. This causes the frame check sequence to not be located at the "end" of the packet resulting in ethernet frame check errors. The driver does work currently, but stricter kernel facing networking solutions like OpenVSwitch will drop these packets as invalid. These changes set the packet size correctly so that these errors no longer occur. The length does not include the frame check sequence, so that subtraction was removed. Tested on Oracle/SUN Multithreaded 10-Gigabit Ethernet Network Controller [108e:abcd] and validated in wireshark. Signed-off-by:
