Pull s390 fixes from Heiko Carstens: - With CONFIG_VMAP_STACK enabled it is not possible to load the s390 specific diag288_wdt watchdog module. The reason is that a pointer to a string is passed to an inline assembly; this string however is located on the stack, while the instruction within the inline assembly expects a physicial address. Fix this by copying the string to a kmalloc'ed buffer. - The diag288_wdt watchdog module does not indicate that it accesses memory from an inline assembly, which it does. Add "memory" to the clobber list to prevent the compiler from optimizing code incorrectly away. - Pass size of the uncompressed kernel image to __decompress() call. Otherwise the kernel image decompressor may corrupt/overwrite an initrd. This was reported to happen on s390 after commit 2aa14b1a ("zstd: import usptream v1.5.2"). * tag 's390-6.2-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/decompressor: specify __decompress() buf len to avoid overflow watchdog: diag288_wdt: fix __diag288() inline assembly watchdog: diag288_wdt: do not use stack buffers for hardware data

The code expect the PHY to be in power down which is only true after reset. Allow changes of the SGMII parameters more than once. Only power down when reconfiguring to avoid bouncing the link when there's no reason to - based on code from Russell King. There are cases when the SGMII_PHYA_PWD register contains 0x9 which prevents SGMII from working. The SGMII still shows link but no traffic can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was taken from a good working state of the SGMII interface.

The test tool can check that the zerocopy number of completions value is valid taking into consideration the number of datagram send calls. This can catch the system into a state where the datagrams are still in the system (for example in a qdisk, waiting for the network interface to return a completion notification, etc).

Commit 2dc0b46b ("libata: sata_down_spd_limit should return if driver has not recorded sstatus speed") changed the behavior of sata_down_spd_limit() to return doing nothing if a drive does not report a current link speed, to avoid reducing the link speed to the lowest 1.5 Gbps speed. However, the change assumed that a speed was recorded before probing (e.g. before a suspend/resume) and set in link->sata_spd. This causes problems with adapters/drives combination failing to establish a link speed during probe autonegotiation. One example reported of this problem is an mvebu adapter with a 3Gbps port-multiplier box: autonegotiation fails, leaving no recorded link speed and no reported current link speed. Probe retries also fail as no action is taken by sata_set_spd() after each retry. Fix this by returning early in sata_down_spd_limit() only if we do have a recorded link speed, that is, if link->sata_spd is not 0. With this fix, a failed probe not leading to a recorded link speed is retried at the lower 1.5 Gbps speed, with the link speed potentially increased later on the second revalidate of the device if the device reports that it supports higher link speeds.

The timer for the transmission of isotp PDUs formerly had two functions: 1. send two consecutive frames with a given time gap 2. monitor the timeouts for flow control frames and the echo frames This led to larger txstate checks and potentially to a problem discovered by syzbot which enabled the panic_on_warn feature while testing. The former 'txtimer' function is split into 'txfrtimer' and 'txtimer' to handle the two above functionalities with separate timer callbacks. The two simplified timers now run in one-shot mode and make the state transitions (especially with isotp_rcv_echo) better understandable.

A CAN XL device is always capable to process CAN FD frames. The former check when sending CAN FD frames relied on the existence of a CAN FD device and did not check for a CAN XL device that would be correct too. With this patch the CAN FD feature is enabled automatically when CAN XL is switched on - and CAN FD cannot be switch off while CAN XL is enabled. This precondition also leads to a clean up and reduction of checks in the hot path in raw_rcv() and raw_sendmsg(). Some conditions are reordered to handle simple checks first. changes since v1: https://lore.kernel.org/all/20230131091012.50553-1-socketcan@hartkopp.net - fixed typo: devive -> device changes since v2: https://lore.kernel.org/all/20230131091824.51026-1-socketcan@hartkopp.net/ - reorder checks in if statements to handle simple checks first Fixes: 62633269 ("can: raw: add CAN XL support") Signed-off-by:

The conclusion "j1939_session_deactivate() should be called with a session ref-count of at least 2" is incorrect. In some concurrent scenarios, j1939_session_deactivate can be called with the session ref-count less than 2. But there is not any problem because it will check the session active state before session putting in j1939_session_deactivate_locked(). Here is the concurrent scenario of the problem reported by syzbot and my reproduction log. cpu0 cpu1 j1939_xtp_rx_eoma j1939_xtp_rx_abort_one j1939_session_get_by_addr [kref == 2] j1939_session_get_by_addr [kref == 3] j1939_session_deactivate [kref == 2] j1939_session_put [kref == 1] j1939_session_completed j1939_session_deactivate WARN_ON_ONCE(kref < 2) ===================================================== WARNING: CPU: 1 PID: 21 at net/can/j1939/transport.c:1088 j1939_session_deactivate+0x5f/0x70 CPU: 1 PID: 21 Comm: ksoftirqd/1 Not tainted 5.14.0-rc7+ #32 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1 04/01/2014 RIP: 0010:j1939_session_deactivate+0x5f/0x70 Call Trace: j1939_session_deactivate_activate_next+0x11/0x28 j1939_xtp_rx_eoma+0x12a/0x180 j1939_tp_recv+0x4a2/0x510 j1939_can_recv+0x226/0x380 can_rcv_filter+0xf8/0x220 can_receive+0x102/0x220 ? process_backlog+0xf0/0x2c0 can_rcv+0x53/0xf0 __netif_receive_skb_one_core+0x67/0x90 ? process_backlog+0x97/0x2c0 __netif_receive_skb+0x22/0x80 Fixes: 0c71437d ("can: j1939: j1939_session_deactivate(): clarify lifetime of session object") Reported-by: syzbot+9981a614060dcee6eeca@syzkaller.appspotmail.com Signed-off-by:Ziyang Xuan <william.xuanziyang@huawei.com> Acked-by:

netvsc_dma_map() and netvsc_dma_unmap() currently check the cp_partial flag and adjust the page_count so that pagebuf entries for the RNDIS portion of the message are skipped when it has already been copied into a send buffer. But this adjustment has already been made by code in netvsc_send(). The duplicate adjustment causes some pagebuf entries to not be mapped. In a normal VM, this doesn't break anything because the mapping doesn’t change the PFN. But in a Confidential VM, dma_map_single() does bounce buffering and provides a different PFN. Failing to do the mapping causes the wrong PFN to be passed to Hyper-V, and various errors ensue. Fix this by removing the duplicate adjustment in netvsc_dma_map() and netvsc_dma_unmap().

Thomas Winter says: ==================== ip/ip6_gre: Fix GRE tunnels not generating IPv6 link local addresses For our point-to-point GRE tunnels, they have IN6_ADDR_GEN_MODE_NONE when they are created then we set IN6_ADDR_GEN_MODE_EUI64 when they come up to generate the IPv6 link local address for the interface. Recently we found that they were no longer generating IPv6 addresses. Also, non-point-to-point tunnels were not generating any IPv6 link local address and instead generating an IPv6 compat address, breaking IPv6 communication on the tunnel. These failures were caused by commit e5dd7294 and this patch set aims to resolve these issues. ==================== Link: https://lore.kernel.org/r/20230131034646.237671-1-Thomas.Winter@alliedtelesis.co.nzSigned-off-by:

We recently found that our non-point-to-point tunnels were not generating any IPv6 link local address and instead generating an IPv6 compat address, breaking IPv6 communication on the tunnel. Previously, addrconf_gre_config always would call addrconf_addr_gen and generate a EUI64 link local address for the tunnel. Then commit e5dd7294 changed the code path so that add_v4_addrs is called but this only generates a compat IPv6 address for non-point-to-point tunnels. I assume the compat address is specifically for SIT tunnels so have kept that only for SIT - GRE tunnels now always generate link local addresses.

For our point-to-point GRE tunnels, they have IN6_ADDR_GEN_MODE_NONE when they are created then we set IN6_ADDR_GEN_MODE_EUI64 when they come up to generate the IPv6 link local address for the interface. Recently we found that they were no longer generating IPv6 addresses. This issue would also have affected SIT tunnels. Commit e5dd7294 changed the code path so that GRE tunnels generate an IPv6 address based on the tunnel source address. It also changed the code path so GRE tunnels don't call addrconf_addr_gen in addrconf_dev_config which is called by addrconf_sysctl_addr_gen_mode when the IN6_ADDR_GEN_MODE is changed. This patch aims to fix this issue by moving the code in addrconf_notify which calls the addr gen for GRE and SIT into a separate function and calling it in the places that expect the IPv6 address to be generated. The previous addrconf_dev_config is renamed to addrconf_eth_config since it only expected eth type interfaces and follows the addrconf_gre/sit_config format. A part of this changes means that the loopback address will be attempted to be configured when changing addr_gen_mode for lo. This should not be a problem because the address should exist anyway and if does already exist then no error is produced.
