The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this using "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/net` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by:

Commit d2825fa9 ("crypto: sm3,sm4 - move into crypto directory") moves SM3 and SM4 algorithm implementations from stand-alone library to crypto API. The corresponding configuration options for the API version (generic) are CONFIG_CRYPTO_SM3_GENERIC and CONFIG_CRYPTO_SM4_GENERIC, respectively. Replace option selected in selftests configuration from the library version to the API version. Fixes: d2825fa9 ("crypto: sm3,sm4 - move into crypto directory") Reported-by:

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 ...

Wei Chen reported a NULL deref in sk_user_ns() [0][1], and Paolo diagnosed the root cause: in unix_diag_get_exact(), the newly allocated skb does not have sk. [2] We must get the user_ns from the NETLINK_CB(in_skb).sk and pass it to sk_diag_fill().

The am65-cpsw driver supports configuring all RGMII variants at interface speed of 10 Mbps. However, in the process of shifting to the PHYLINK framework, the support for all variants of RGMII except the PHY_INTERFACE_MODE_RGMII variant was accidentally removed. Fix this by using phy_interface_mode_is_rgmii() to check for all variants of RGMII mode. Fixes: e8609e69 ("net: ethernet: ti: am65-cpsw: Convert to PHYLINK") Reported-by:

e1000_xmit_frame is expected to stop the queue and dispatch frames to hardware if there is not sufficient space for the next frame in the buffer, but sometimes it failed to do so because the estimated maximum size of frame was wrong. As the consequence, the later invocation of e1000_xmit_frame failed with NETDEV_TX_BUSY, and the frame in the buffer remained forever, resulting in a watchdog failure. This change fixes the estimated size by making it match with the condition for NETDEV_TX_BUSY. Apparently, the old estimation failed to account for the following lines which determines the space requirement for not causing NETDEV_TX_BUSY: ``` /* reserve a descriptor for the offload context */ if ((mss) || (skb->ip_summed == CHECKSUM_PARTIAL)) count++; count++; count += DIV_ROUND_UP(len, adapter->tx_fifo_limit); ``` This issue was found when running http-stress02 test included in Linux Test Project 20220930 on QEMU with the following commandline: ``` qemu-system-x86_64 -M q35,accel=kvm -m 8G -smp 8 -drive if=virtio,format=raw,file=root.img,file.locking=on -device e1000e,netdev=netdev -netdev tap,script=ifup,downscript=no,id=netdev ``` Fixes: bc7f75fa ("[E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)") Signed-off-by:Naama Meir <naamax.meir@linux.intel.com> Signed-off-by:
