2025-03-17efivarfs: use I_MUTEX_CHILD nested lock to traverse variables on resumeArd Biesheuvel
syzbot warns about a potential deadlock, but this is a false positive resulting from a missing lockdep annotation: iterate_dir() locks the parent whereas the inode_lock() it warns about locks the child, which is guaranteed to be a different lock. So use inode_lock_nested() instead with the appropriate lock class.

2025-03-17ASoC: soc-utils: Transition to the faux device interfaceSudeep Holla
The ASoC soc-utils driver does not require the creation of a platform device. Originally, this approach was chosen for simplicity when the driver was first implemented. With the introduction of the lightweight faux device interface, we now have a more appropriate alternative. Migrate the driver to utilize the faux bus, given that the platform device it previously created was not a real one anyway. This will simplify the code, reducing its footprint while maintaining functionality.

2025-03-17printk: Add an option to allow ttynull to be a default console deviceAdam Simonelli
The new option is CONFIG_NULL_TTY_DEFAULT_CONSOLE. if enabled, and CONFIG_VT is disabled, ttynull will become the default primary console device. ttynull will be the only console device usually with this option enabled. Some architectures do call add_preferred_console() which may add another console though. Motivation: Many distributions ship with CONFIG_VT enabled. On tested desktop hardware if CONFIG_VT is disabled, the default console device falls back to /dev/ttyS0 instead of /dev/tty. This could cause issues in user space, and hardware problems: 1. The user space issues include the case where /dev/ttyS0 is disconnected, and the TCGETS ioctl, which some user space libraries use as a probe to determine if a file is a tty, is called on /dev/console and fails. Programs that call isatty() on /dev/console and get an incorrect false value may skip expected logging to /dev/console. 2. The hardware issues include the case if a user has a science instrument or other device connected to the /dev/ttyS0 port, and they were to upgrade to a kernel that is disabling the CONFIG_VT option, kernel logs will then be sent to the device connected to /dev/ttyS0 unless they edit their kernel command line manually. The new CONFIG_NULL_TTY_DEFAULT_CONSOLE option will give users and distribution maintainers an option to avoid this. Disabling CONFIG_VT and enabling CONFIG_NULL_TTY_DEFAULT_CONSOLE will ensure the default kernel console behavior is not dependent on hardware configuration by default, and avoid unexpected new behavior on devices connected to the /dev/ttyS0 serial port.

2025-03-17tcp: add new TCP_TW_ACK_OOW state and allow ECN bits in TOSIlpo Järvinen
ECN bits in TOS are always cleared when sending in ACKs in TW. Clearing them is problematic for TCP flows that used Accurate ECN because ECN bits decide which service queue the packet is placed into (L4S vs Classic). Effectively, TW ACKs are always downgraded from L4S to Classic queue which might impact, e.g., delay the ACK will experience on the path compared with the other packets of the flow. Change the TW ACK sending code to differentiate: - In tcp_v4_send_reset(), commit ba9e04a7ddf4f ("ip: fix tos reflection in ack and reset packets") cleans ECN bits for TW reset and this is not affected. - In tcp_v4_timewait_ack(), ECN bits for all TW ACKs are cleaned. But now only ECN bits of ACKs for oow data or paws_reject are cleaned, and ECN bits of other ACKs will not be cleaned. - In tcp_v4_reqsk_send_ack(), commit 66b13d99d96a1 ("ipv4: tcp: fix TOS value in ACK messages sent from TIME_WAIT") did not clean ECN bits of ACKs for oow data or paws_reject.

There are important differences in how the CWR field behaves in RFC3168 and AccECN.

Also, if CWR is there, set the Accurate ECN GSO flag to avoid corrupting CWR flag somewhere.

2025-03-17gso: AccECN supportIlpo Järvinen
Handling the CWR flag differs between RFC 3168 ECN and AccECN. With RFC 3168 ECN aware TSO (NETIF_F_TSO_ECN) CWR flag is cleared starting from 2nd segment which is incompatible how AccECN handles the CWR flag. Such super-segments are indicated by SKB_GSO_TCP_ECN. With AccECN, CWR flag (or more accurately, the ACE field that also includes ECE & AE flags) changes only when new packet(s) with CE mark arrives so the flag should not be changed within a super-skb. The new skb/feature flags are necessary to prevent such TSO engines corrupting AccECN ACE counters by clearing the CWR flag (if the CWR handling feature cannot be turned off). If NIC is completely unaware of RFC3168 ECN (doesn't support NETIF_F_TSO_ECN) or its TSO engine can be set to not touch CWR flag despite supporting also NETIF_F_TSO_ECN, TSO could be safely used with AccECN on such NIC. This should be evaluated per NIC basis (not done in this patch series for any NICs). For the cases, where TSO cannot keep its hands off the CWR flag, a GSO fallback is provided by this patch.

2025-03-17objtool: Add CONFIG_OBJTOOL_WERRORJosh Poimboeuf
Objtool warnings can be indicative of crashes, broken live patching, or even boot failures. Ignoring them is not recommended. Add CONFIG_OBJTOOL_WERROR to upgrade objtool warnings to errors by enabling the objtool --Werror option. Also set --backtrace to print the branches leading up to the warning, which can help considerably when debugging certain warnings. To avoid breaking bots too badly for now, make it the default for real world builds only (!COMPILE_TEST).

2025-03-17objtool: Create backup on error and print argsJosh Poimboeuf
Recreating objtool errors can be a manual process. Kbuild removes the object, so it has to be compiled or linked again before running objtool. Then the objtool args need to be reversed engineered. Make that all easier by automatically making a backup of the object file on error, and print a modified version of the args which can be used to recreate.
