Eric Dumazet said: > I was thinking about adding a debug check in skb_inner_network_header() > if inner_network_header is zero (that would mean it is not 'set' yet), > but this would trigger even after your patch. So add new skb_inner_network_header_was_set() helper and use that. The syzbot reproducer injects data via packet socket. The skb that gets allocated and passed down the stack has ->protocol set to NSH (0x894f) and gso_type set to SKB_GSO_UDP | SKB_GSO_DODGY. This gets passed to skb_mac_gso_segment(), which sees NSH as ptype to find a callback for. nsh_gso_segment() retrieves next type: proto = tun_p_to_eth_p(nsh_hdr(skb)->np); ... which is MPLS (TUN_P_MPLS_UC). It updates skb->protocol and then calls mpls_gso_segment(). Inner offsets are all 0, so mpls_gso_segment() ends up with a negative header size. In case more callers rely on silent handling of such large may_pull values we could also 'legalize' this behaviour, either replacing the debug check with (len > INT_MAX) test or removing it and instead adding a comment before existing if (unlikely(len > skb->len)) return SKB_DROP_REASON_PKT_TOO_SMALL; test in pskb_may_pull_reason(), saying that this check also implicitly takes care of callers that miscompute header sizes.

At boot it is set to clamshell (bit 6 set) only after method VBDL is executed. Since VBDL is now evaluated in the probe routine later, after the device is registered, the retrieved value of VBDS was still 0 ("tablet mode") when setting up the virtual switch. Make sure to evaluate VGBS after VBDL, to ensure the convertible boots in clamshell mode, the expected default.

* virtio: reenable config if freezing device failedDavid Hildenbrand2024-04-131-2/+8
| | | | | | | | | | | | | | | | | | | | | | | commit 310227f42882c52356b523e2f4e11690eebcd2ab upstream. Currently, we don't reenable the config if freezing the device failed. For example, virtio-mem currently doesn't support suspend+resume, and trying to freeze the device will always fail. Afterwards, the device will no longer respond to resize requests, because it won't get notified about config changes. Let's fix this by re-enabling the config if freezing fails.

* scsi: sd: usb_storage: uas: Access media prior to querying device propertiesMartin K. Petersen2024-04-134-1/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 321da3dc1f3c92a12e3c5da934090d2992a8814c ] It has been observed that some USB/UAS devices return generic properties hardcoded in firmware for mode pages for a period of time after a device has been discovered. The reported properties are either garbage or they do not accurately reflect the characteristics of the physical storage device attached in the case of a bridge. Prior to commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to avoid calling revalidate twice") we would call revalidate several times during device discovery. As a result, incorrect values would eventually get replaced with ones accurately describing the attached storage. When we did away with the redundant revalidate pass, several cases were reported where devices reported nonsensical values or would end up in write-protected state. An initial attempt at addressing this issue involved introducing a delayed second revalidate invocation. However, this approach still left some devices reporting incorrect characteristics. Tasos Sahanidis debugged the problem further and identified that introducing a READ operation prior to MODE SENSE fixed the problem and that it wasn't a timing issue. Issuing a READ appears to cause the devices to update their state to reflect the actual properties of the storage media. Device properties like vendor, model, and storage capacity appear to be correctly reported from the get-go. It is unclear why these devices defer populating the remaining characteristics. Match the behavior of a well known commercial operating system and trigger a READ operation prior to querying device characteristics to force the device to populate the mode pages. The additional READ is triggered by a flag set in the USB storage and UAS drivers. We avoid issuing the READ for other transport classes since some storage devices identify Linux through our particular discovery command sequence.

| | | | | | | | | | | | | | | | | | [ Upstream commit a75e0684efe567ae5f6a8e91a8360c4c1773cf3a ] If a DiplayPort cable is directly connected to the host routers USB4 port, there is no tunnel involved but the port is in "redrive" mode meaning that it is re-driving the DisplayPort signals from its DisplayPort source. In this case we need to keep the domain powered on otherwise once the domain enters D3cold the connected monitor blanks too. Since this happens only on Intel Barlow Ridge add a quirk that takes runtime PM reference if we detect that the USB4 port entered redrive mode (and release it once it exits the mode).

* bus: mhi: host: Add MHI_PM_SYS_ERR_FAIL stateJeffrey Hugo2024-04-133-6/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit bce3f770684cc1d91ff9edab431b71ac991faf29 ] When processing a SYSERR, if the device does not respond to the MHI_RESET from the host, the host will be stuck in a difficult to recover state. The host will remain in MHI_PM_SYS_ERR_PROCESS and not clean up the host channels. Clients will not be notified of the SYSERR via the destruction of their channel devices, which means clients may think that the device is still up. Subsequent SYSERR events such as a device fatal error will not be processed as the state machine cannot transition from PROCESS back to DETECT. The only way to recover from this is to unload the mhi module (wipe the state machine state) or for the mhi controller to initiate SHUTDOWN. This issue was discovered by stress testing soc_reset events on AIC100 via the sysfs node. soc_reset is processed entirely in hardware. When the register write hits the endpoint hardware, it causes the soc to reset without firmware involvement. In stress testing, there is a rare race where soc_reset N will cause the soc to reset and PBL to signal SYSERR (fatal error). If soc_reset N+1 is triggered before PBL can process the MHI_RESET from the host, then the soc will reset again, and re-run PBL from the beginning. This will cause PBL to lose all state. PBL will be waiting for the host to respond to the new syserr, but host will be stuck expecting the previous MHI_RESET to be processed. Additionally, the AMSS EE firmware (QSM) was hacked to synthetically reproduce the issue by simulating a FW hang after the QSM issued a SYSERR. In this case, soc_reset would not recover the device. For this failure case, to recover the device, we need a state similar to PROCESS, but can transition to DETECT. There is not a viable existing state to use. POR has the needed transitions, but assumes the device is in a good state and could allow the host to attempt to use the device. Allowing PROCESS to transition to DETECT invites the possibility of parallel SYSERR processing which could get the host and device out of sync. Thus, invent a new state - MHI_PM_SYS_ERR_FAIL This essentially a holding state. It allows us to clean up the host elements that are based on the old state of the device (channels), but does not allow us to directly advance back to an operational state. It does allow the detection and processing of another SYSERR which may recover the device, or allows the controller to do a clean shutdown.

| | | | | | | | | | | | | | | | | | | | | | [ Upstream commit d8b945fa475f13d787df00c26a6dc45a3e2e1d1d ] There's issue as follows When do IO fault injection test: Quota error (device dm-3): find_block_dqentry: Quota for id 101 referenced but not present Quota error (device dm-3): qtree_read_dquot: Can't read quota structure for id 101 Quota error (device dm-3): do_check_range: Getting block 2021161007 out of range 1-186 Quota error (device dm-3): qtree_read_dquot: Can't read quota structure for id 661 Now, ext4_write_dquot()/ext4_acquire_dquot()/ext4_release_dquot() may commit inconsistent quota data even if process failed. This may lead to filesystem corruption. To ensure filesystem consistent when errors=remount-ro there is need to call ext4_handle_error() to abort journal.

* ext4: add a hint for block bitmap corrupt state in mb_groupsZhang Yi2024-04-131-1/+4
| | | | | | | | | | | | | | | | | [ Upstream commit 68ee261fb15457ecb17e3683cb4e6a4792ca5b71 ] If one group is marked as block bitmap corrupted, its free blocks cannot be used and its free count is also deducted from the global sbi->s_freeclusters_counter. User might be confused about the absent free space because we can't query the information about corrupted block groups except unreliable error messages in syslog. So add a hint to show block bitmap corrupted groups in mb_groups.

* rcu-tasks: Repair RCU Tasks Trace quiescence checkPaul E. McKenney2024-04-131-2/+2
| | | | | | | | | | | | | | | | | | | [ Upstream commit 2eb52fa8900e642b3b5054c4bf9776089d2a935f ] The context-switch-time check for RCU Tasks Trace quiescence expects current->trc_reader_special.b.need_qs to be zero, and if so, updates it to TRC_NEED_QS_CHECKED. This is backwards, because if this value is zero, there is no RCU Tasks Trace grace period in flight, an thus no need for a quiescent state. Instead, when a grace period starts, this field is set to TRC_NEED_QS. This commit therefore changes the check from zero to TRC_NEED_QS.

* isofs: handle CDs with bad root inode but good Joliet root directoryAlex Henrie2024-04-131-2/+16
| | | | | | | | | | | | | | | | | | | | [ Upstream commit 4243bf80c79211a8ca2795401add9c4a3b1d37ca ] I have a CD copy of the original Tom Clancy's Ghost Recon game from 2001. The disc mounts without error on Windows, but on Linux mounting fails with the message "isofs_fill_super: get root inode failed". The error originates in isofs_read_inode, which returns -EIO because de_len is 0. The superblock on this disc appears to be intentionally corrupt as a form of copy protection. When the root inode is unusable, instead of giving up immediately, try to continue with the Joliet file table. This fixes the Ghost Recon CD and probably other copy-protected CDs too.
