2025-03-25Bluetooth: hci_uart: Fix another race during initializationArseniy Krasnov
Do not set 'HCI_UART_PROTO_READY' before call 'hci_uart_register_dev()'. Possible race is when someone calls 'hci_tty_uart_close()' after this bit is set, but 'hci_uart_register_dev()' wasn't done. This leads to access to uninitialized fields. To fix it let's set this bit after device was registered (as before patch c411c62cc133) and to fix previous problem let's add one more bit in addition to 'HCI_UART_PROTO_READY' which allows to perform power up without original bit set (pls see commit c411c62cc133).

2025-03-25Bluetooth: hci_uart: fix race during initializationArseniy Krasnov
'hci_register_dev()' calls power up function, which is executed by kworker - 'hci_power_on()'. This function does access to bluetooth chip using callbacks from 'hci_ldisc.c', for example 'hci_uart_send_frame()'. Now 'hci_uart_send_frame()' checks 'HCI_UART_PROTO_READY' bit set, and if not - it fails. Problem is that 'HCI_UART_PROTO_READY' is set after 'hci_register_dev()', and there is tiny chance that 'hci_power_on()' will be executed before setting this bit. In that case HCI init logic fails. Patch moves setting of 'HCI_UART_PROTO_READY' before calling function 'hci_uart_register_dev()'.

Commit 809265fe96fe ("net: phy: c45: remove local advertisement parameter from genphy_c45_eee_is_active") stopped reading the local advertisement from the PHY earlier in this development cycle, which broke "ethtool --set-eee ethX eee off". When ethtool is used to set EEE off, genphy_c45_eee_is_active() indicates that EEE was active if the link partner reported an advertisement, which causes phylib to set phydev->enable_tx_lpi on link up, despite our local advertisement in hardware being empty. However, phydev->advertising_eee is preserved while EEE is turned off, which leads to genphy_c45_eee_is_active() incorrectly reporting that EEE is active. Fix it by checking phydev->eee_cfg.eee_enabled, and if clear, immediately indicate that EEE is not active.

When adding a socket option support in MPTCP, both the get and set parts are supposed to be implemented. IPV6_V6ONLY support for the setsockopt part has been added a while ago, but it looks like the get part got forgotten. It should have been present as a way to verify a setting has been set as expected, and not to act differently from TCP or any other socket types. Not supporting this getsockopt(IPV6_V6ONLY) blocks some apps which want to check the default value, before doing extra actions. On Linux, the default value is 0, but this can be changed with the net.ipv6.bindv6only sysctl knob. On Windows, it is set to 1 by default. So supporting the get part, like for all other socket options, is important. Everything was in place to expose it, just the last step was missing. Only new code is added to cover this specific getsockopt(), that seems safe.

2025-03-21Merge branch 'netconsole-add-support-for-userdata-release'Paolo Abeni
Breno Leitao says: ==================== netconsole: Add support for userdata release I am submitting a series of patches that introduce a new feature for the netconsole subsystem, specifically the addition of the 'release' field to the sysdata structure. This feature allows the kernel release/version to be appended to the userdata dictionary in every message sent, enhancing the information available for debugging and monitoring purposes. This complements the already supported release prepend feature, which was added some time ago. The release prepend appends the release information at the message header, which is not ideal for two reasons: 1) It is difficult to determine if a message includes this information, making it hard and resource-intensive to parse. 2) When a message is fragmented, the release information is appended to every message fragment, consuming valuable space in the packet. The "release prepend" feature was created before the concept of userdata and sysdata. Now that this format has proven successful, we are implementing the release feature as part of this enhanced structure. This patch series aims to improve the netconsole subsystem by providing a more efficient and user-friendly way to include kernel release information in messages. I believe these changes will significantly aid in system analysis and troubleshooting.
