[ Upstream commit 6b6e2e8 ] The `pmbus_identify()` function fails to correctly determine the number of supported pages on PMBus devices. This occurs because `info->pages` is implicitly zero-initialised, and `pmbus_set_page()` does not perform writes to the page register if `info->pages` is not yet initialised. Without this patch, `info->pages` is always set to the maximum after scanning. This patch initialises `info->pages` to `PMBUS_PAGES` before the probing loop, enabling `pmbus_set_page()` writes to make it out onto the bus correctly identifying the number of pages. `PMBUS_PAGES` seemed like a reasonable non-zero number because that's the current result of the identification process. Testing was done with a PMBus device in QEMU.

[ Upstream commit 4c2d14c ] Syzbot caught an "KMSAN: uninit-value" warning [1], which is caused by the ppp driver not initializing a 2-byte header when using socket filter. The following code can generate a PPP filter BPF program: ''' struct bpf_program fp; pcap_t *handle; handle = pcap_open_dead(DLT_PPP_PPPD, 65535); pcap_compile(handle, &fp, "ip and outbound", 0, 0); bpf_dump(&fp, 1); ''' Its output is: ''' (000) ldh [2] (001) jeq #0x21 jt 2 jf 5 (002) ldb [0] (003) jeq #0x1 jt 4 jf 5 (004) ret #65535 (005) ret #0 ''' Wen can find similar code at the following link: https://github.com/ppp-project/ppp/blob/master/pppd/options.c#L1680 The maintainer of this code repository is also the original maintainer of the ppp driver. As you can see the BPF program skips 2 bytes of data and then reads the 'Protocol' field to determine if it's an IP packet. Then it read the first byte of the first 2 bytes to determine the direction. The issue is that only the first byte indicating direction is initialized in current ppp driver code while the second byte is not initialized. For normal BPF programs generated by libpcap, uninitialized data won't be used, so it's not a problem. However, for carefully crafted BPF programs, such as those generated by syzkaller [2], which start reading from offset 0, the uninitialized data will be used and caught by KMSAN.

[ Upstream commit b33a534 ] Currently, VLAN devices can be created on top of non-ethernet devices. Besides the fact that it doesn't make much sense, this also causes a bug which leaks the address of a kernel function to usermode. When creating a VLAN device, we initialize GARP (garp_init_applicant) and MRP (mrp_init_applicant) for the underlying device. As part of the initialization process, we add the multicast address of each applicant to the underlying device, by calling dev_mc_add. __dev_mc_add uses dev->addr_len to determine the length of the new multicast address. This causes an out-of-bounds read if dev->addr_len is greater than 6, since the multicast addresses provided by GARP and MRP are only 6 bytes long. This behaviour can be reproduced using the following commands: ip tunnel add gretest mode ip6gre local ::1 remote ::2 dev lo ip l set up dev gretest ip link add link gretest name vlantest type vlan id 100 Then, the following command will display the address of garp_pdu_rcv: ip maddr show | grep 01:80:c2:00:00:21 Fix the bug by enforcing the type of the underlying device during VLAN device initialization.

[ Upstream commit 0d3e0df ] The total size calculated for EPC can overflow u64 given the added up page for SECS. Further, the total size calculated for shmem can overflow even when the EPC size stays within limits of u64, given that it adds the extra space for 128 byte PCMD structures (one for each page). Address this by pre-evaluating the micro-architectural requirement of SGX: the address space size must be power of two. This is eventually checked up by ECREATE but the pre-check has the additional benefit of making sure that there is some space for additional data.

[ Upstream commit 3c9231e ] When I read through the TSO codes, I found out that we probably miss initializing the tx_flags of last seg when TSO is turned off, which means at the following points no more timestamp (for this last one) will be generated. There are three flags to be handled in this patch: 1. SKBTX_HW_TSTAMP 2. SKBTX_BPF 3. SKBTX_SCHED_TSTAMP Note that SKBTX_BPF[1] was added in 6.14.0-rc2 by commit 6b98ec7 ("bpf: Add BPF_SOCK_OPS_TSTAMP_SCHED_CB callback") and only belongs to net-next branch material for now. The common issue of the above three flags can be fixed by this single patch. This patch initializes the tx_flags to SKBTX_ANY_TSTAMP like what the UDP GSO does to make the newly segmented last skb inherit the tx_flags so that requested timestamp will be generated in each certain layer, or else that last one has zero value of tx_flags which leads to no timestamp at all.

[ Upstream commit 5ac6024 ] The parameters set by the set_params call are only applied to the block device in the start_dev call. So if a device has already been started, a subsequently issued set_params on that device will not have the desired effect, and should return an error. There is an existing check for this - set_params fails on devices in the LIVE state. But this check is not sufficient to cover the recovery case. In this case, the device will be in the QUIESCED or FAIL_IO states, so set_params will succeed. But this success is misleading, because the parameters will not be applied, since the device has already been started (by a previous ublk server). The bit UB_STATE_USED is set on completion of the start_dev; use it to detect and fail set_params commands which arrive too late to be applied (after start_dev).

[ Upstream commit 3b4035d ] child_cfs_rq_on_list attempts to convert a 'prev' pointer to a cfs_rq. This 'prev' pointer can originate from struct rq's leaf_cfs_rq_list, making the conversion invalid and potentially leading to memory corruption. Depending on the relative positions of leaf_cfs_rq_list and the task group (tg) pointer within the struct, this can cause a memory fault or access garbage data. The issue arises in list_add_leaf_cfs_rq, where both cfs_rq->leaf_cfs_rq_list and rq->leaf_cfs_rq_list are added to the same leaf list. Also, rq->tmp_alone_branch can be set to rq->leaf_cfs_rq_list. This adds a check `if (prev == &rq->leaf_cfs_rq_list)` after the main conditional in child_cfs_rq_on_list. This ensures that the container_of operation will convert a correct cfs_rq struct. This check is sufficient because only cfs_rqs on the same CPU are added to the list, so verifying the 'prev' pointer against the current rq's list head is enough. Fixes a potential memory corruption issue that due to current struct layout might not be manifesting as a crash but could lead to unpredictable behavior when the layout changes.

commit 2b66ef8 upstream. The xHC resources allocated for USB devices are not released in correct order after resuming in case when while suspend device was reconnected. This issue has been detected during the fallowing scenario: - connect hub HS to root port - connect LS/FS device to hub port - wait for enumeration to finish - force host to suspend - reconnect hub attached to root port - wake host For this scenario during enumeration of USB LS/FS device the Cadence xHC reports completion error code for xHC commands because the xHC resources used for devices has not been properly released. XHCI specification doesn't mention that device can be reset in any order so, we should not treat this issue as Cadence xHC controller bug. Similar as during disconnecting in this case the device resources should be cleared starting form the last usb device in tree toward the root hub. To fix this issue usbcore driver should call hcd->driver->reset_device for all USB devices connected to hub which was reconnected while suspending.

commit f13409b upstream. It's not possible to call nvme_state_ctrl_state with holding a spin lock, because nvme_state_ctrl_state calls cancel_delayed_work_sync when fastfail is enabled. Instead syncing the ASSOC_FLAG and state transitions using a lock, it's possible to only rely on the state machine transitions. That means nvme_fc_ctrl_connectivity_loss should unconditionally call nvme_reset_ctrl which avoids the read race on the ctrl state variable. Actually, it's not necessary to test in which state the ctrl is, the reset work will only scheduled when the state machine is in LIVE state. In nvme_fc_create_association, the LIVE state can only be entered if it was previously CONNECTING. If this is not possible then the reset handler got triggered. Thus just error out here.

commit 221cea1 upstream. Remove the fixup to make the Omoton KB066's F6 key F6 when not holding Fn. That was really just a hack to allow typing F6 in fnmode>0, and it didn't fix any of the other F keys that were likewise untypable in fnmode>0. Instead, because the Omoton's Fn key is entirely internal to the keyboard, completely disable Fn key translation when an Omoton is detected, which will prevent the hid-apple driver from interfering with the keyboard's built-in Fn key handling. All of the F keys, including F6, are then typable when Fn is held. The Omoton KB066 and the Apple A1255 both have HID product code 05ac:022c. The self-reported name of every original A1255 when they left the factory was "Apple Wireless Keyboard". By default, Mac OS changes the name to "<username>'s keyboard" when pairing with the keyboard, but Mac OS allows the user to set the internal name of Apple keyboards to anything they like. The Omoton KB066's name, on the other hand, is not configurable: It is always "Bluetooth Keyboard". Because that name is so generic that a user might conceivably use the same name for a real Apple keyboard, detect Omoton keyboards based on both having that exact name and having HID product code 022c.

commit afb41b0 upstream. In H2CTermReq, a FES with value 0x05 means "R2T Limit Exceeded"; but in C2HTermReq the same value has a different meaning (Data Transfer Limit Exceeded).

commit 7395dfa upstream. Add a timestamp field at the beginning of the transaction, store it in the nftables per-netns area. Update set backend .insert, .deactivate and sync gc path to use the timestamp, this avoids that an element expires while control plane transaction is still unfinished. .lookup and .update, which are used from packet path, still use the current time to check if the element has expired. And .get path and dump also since this runs lockless under rcu read size lock. Then, there is async gc which also needs to check the current time since it runs asynchronously from a workqueue.

commit 3c13725 upstream. All existing NFT_EXPR_STATEFUL provide a .clone interface, remove fallback to copy content of stateful expression since this is never exercised and bail out if .clone interface is not defined.

commit fa23e0d upstream. Sven Auhagen reports transaction failures with following error: ./main.nft:13:1-26: Error: Could not process rule: Cannot allocate memory percpu: allocation failed, size=16 align=8 atomic=1, atomic alloc failed, no space left This points to failing pcpu allocation with GFP_ATOMIC flag. However, transactions happen from user context and are allowed to sleep. One case where we can call into percpu allocator with GFP_ATOMIC is nft_counter expression. Normally this happens from control plane, so this could use GFP_KERNEL instead. But one use case, element insertion from packet path, needs to use GFP_ATOMIC allocations (nft_dynset expression). At this time, .clone callbacks always use GFP_ATOMIC for this reason. Add gfp_t argument to the .clone function and pass GFP_KERNEL or GFP_ATOMIC flag depending on context, this allows all clone memory allocations to sleep for the normal (transaction) case.
