Cited commit added the table ID to the FIB info structure, but did not prevent structures with different table IDs from being consolidated. This can lead to routes being flushed from a VRF when an address is deleted from a different VRF. Fix by taking the table ID into account when looking for a matching FIB info. This is already done for FIB info structures backed by a nexthop object in fib_find_info_nh(). Add test cases that fail before the fix: # ./fib_tests.sh -t ipv4_del_addr IPv4 delete address route tests Regular FIB info TEST: Route removed from VRF when source address deleted [ OK ] TEST: Route in default VRF not removed [ OK ] TEST: Route removed in default VRF when source address deleted [ OK ] TEST: Route in VRF is not removed by address delete [ OK ] Identical FIB info with different table ID TEST: Route removed from VRF when source address deleted [FAIL] TEST: Route in default VRF not removed [ OK ] RTNETLINK answers: File exists TEST: Route removed in default VRF when source address deleted [ OK ] TEST: Route in VRF is not removed by address delete [FAIL] Tests passed: 6 Tests failed: 2 And pass after: # ./fib_tests.sh -t ipv4_del_addr IPv4 delete address route tests Regular FIB info TEST: Route removed from VRF when source address deleted [ OK ] TEST: Route in default VRF not removed [ OK ] TEST: Route removed in default VRF when source address deleted [ OK ] TEST: Route in VRF is not removed by address delete [ OK ] Identical FIB info with different table ID TEST: Route removed from VRF when source address deleted [ OK ] TEST: Route in default VRF not removed [ OK ] TEST: Route removed in default VRF when source address deleted [ OK ] TEST: Route in VRF is not removed by address delete [ OK ] Tests passed: 8 Tests failed: 0 Fixes: 5a56a0b3 ("net: Don't delete routes in different VRFs") Signed-off-by:Ido Schimmel <idosch@nvidia.com> Reviewed-by:

Prior to the Fixes: commit, the initialization code went through the same fec_enet_set_coalesce() function as used by ethtool, and that function correctly checks whether the current variant has support for irq coalescing. Now that the initialization code instead calls fec_enet_itr_coal_set() directly, that call needs to be guarded by a check for the FEC_QUIRK_HAS_COALESCE bit. Fixes: df727d45 (net: fec: don't reset irq coalesce settings to defaults on "ip link up") Reported-by:

In commit 4d633d1b ("bonding: fix ICMPv6 header handling when receiving IPv6 messages"), there is a copy/paste issue for NA daddr. I found that in my testing and fixed it in my local branch. But I forgot to re-format the patch and sent the wrong mail. Fix it by reading the correct dest address.

There is warning report about of_node refcount leak while probing mdio device: OF: ERROR: memory leak, expected refcount 1 instead of 2, of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node /spi/soc@0/mdio@710700c0/ethernet@4 In of_mdiobus_register_device(), we increase fwnode refcount by fwnode_handle_get() before associating the of_node with mdio device, but it has never been decreased in normal path. Since that, in mdio_device_release(), it needs to call fwnode_handle_put() in addition instead of calling kfree() directly. After above, just calling mdio_device_free() in the error handle path of of_mdiobus_register_device() is enough to keep the refcount balanced. Fixes: a9049e0c ("mdio: Add support for mdio drivers.")

After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be cleared, and another CPU can start napi thread and access per-CQ variable, cq->work_done. If the other thread (for example, from busy_poll) sets it to a value >= budget, this thread will continue to run when it should stop, and cause memory corruption and panic. To fix this issue, save the per-CQ work_done variable in a local variable before napi_complete_done(), so it won't be corrupted by a possible concurrent thread after napi_complete_done(). Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done variable race is fixed, so the driver is able to reliably support features like busy_poll.

By keep sending L2CAP_CONF_REQ packets, chan->num_conf_rsp increases multiple times and eventually it will wrap around the maximum number (i.e., 255). This patch prevents this by adding a boundary check with L2CAP_MAX_CONF_RSP Btmon log: Bluetooth monitor ver 5.64 = Note: Linux version 6.1.0-rc2 (x86_64) 0.264594 = Note: Bluetooth subsystem version 2.22 0.264636 @ MGMT Open: btmon (privileged) version 1.22 {0x0001} 0.272191 = New Index: 00:00:00:00:00:00 (Primary,Virtual,hci0) [hci0] 13.877604 @ RAW Open: 9496 (privileged) version 2.22 {0x0002} 13.890741 = Open Index: 00:00:00:00:00:00 [hci0] 13.900426 (...) > ACL Data RX: Handle 200 flags 0x00 dlen 1033 #32 [hci0] 14.273106 invalid packet size (12 != 1033) 08 00 01 00 02 01 04 00 01 10 ff ff ............ > ACL Data RX: Handle 200 flags 0x00 dlen 1547 #33 [hci0] 14.273561 invalid packet size (14 != 1547) 0a 00 01 00 04 01 06 00 40 00 00 00 00 00 ........@..... > ACL Data RX: Handle 200 flags 0x00 dlen 2061 #34 [hci0] 14.274390 invalid packet size (16 != 2061) 0c 00 01 00 04 01 08 00 40 00 00 00 00 00 00 04 ........@....... > ACL Data RX: Handle 200 flags 0x00 dlen 2061 #35 [hci0] 14.274932 invalid packet size (16 != 2061) 0c 00 01 00 04 01 08 00 40 00 00 00 07 00 03 00 ........@....... = bluetoothd: Bluetooth daemon 5.43 14.401828 > ACL Data RX: Handle 200 flags 0x00 dlen 1033 #36 [hci0] 14.275753 invalid packet size (12 != 1033) 08 00 01 00 04 01 04 00 40 00 00 00 ........@...

On kernel 6.1-rcX, I have been getting the following dmesg error message on every boot, resume from suspend and rfkill unblock of the Bluetooth device: Bluetooth: hci0: HCI_REQ-0xfcf0 After some investigation, it turned out to be caused by commit dd50a864 ("Bluetooth: Delete unreferenced hci_request code") which modified hci_req_add() in net/bluetooth/hci_request.c to always print an error message when it is executed. In my case, the function was executed by msft_set_filter_enable() in net/bluetooth/msft.c, which provides support for Microsoft vendor opcodes. As explained by Brian Gix, "the error gets logged because it is using a deprecated (but still working) mechanism to issue HCI opcodes" [1]. So this is just a debugging tool to show that a deprecated function is executed. As such, it should not be included in the mainline kernel. See for example commit 771c0353 ("deprecate the '__deprecated' attribute warnings entirely and for good") Additionally, this error message is cryptic and the user is not able to do anything about it.

The rationale of showing this is that it's potentially critical information to diagnose and find more CSR compatibility bugs in the future and it will save a lot of headaches. Given that clones come from a wide array of vendors (some are actually Barrot, some are something else) and these numbers are what let us find differences between actual and fake ones, it will be immensely helpful to scour the Internet looking for this pattern and building an actual database to find correlations and improve the checks.

A patch series by a Qualcomm engineer essentially removed my quirk/workaround because they thought it was unnecessary. It wasn't, and it broke everything again: https://patchwork.kernel.org/project/netdevbpf/list/?series=661703&archive=both&state=* He argues that the quirk is not necessary because the code should check if the dongle says if it's supported or not. The problem is that for these Chinese CSR clones they say that it would work: = New Index: 00:00:00:00:00:00 (Primary,USB,hci0) = Open Index: 00:00:00:00:00:00 < HCI Command: Read Local Version Information (0x04|0x0001) plen 0 > HCI Event: Command Complete (0x0e) plen 12 > [hci0] 11.276039 Read Local Version Information (0x04|0x0001) ncmd 1 Status: Success (0x00) HCI version: Bluetooth 5.0 (0x09) - Revision 2064 (0x0810) LMP version: Bluetooth 5.0 (0x09) - Subversion 8978 (0x2312) Manufacturer: Cambridge Silicon Radio (10) ... < HCI Command: Read Local Supported Features (0x04|0x0003) plen 0 > HCI Event: Command Complete (0x0e) plen 68 > [hci0] 11.668030 Read Local Supported Commands (0x04|0x0002) ncmd 1 Status: Success (0x00) Commands: 163 entries ...
