[ Upstream commit b93c2a68f3d9dc98ec30dcb342ae47c1c8d09d18 ] The wakeup bit in the bmAttributes field indicates whether the device is configured for remote wakeup. But this field should be allowed to set only if the UDC supports such wakeup mechanism. So configure this field based on UDC capability. Also inform the UDC whether the device is configured for remote wakeup by implementing a gadget op.

2024-03-06af_unix: Fix task hung while purging oob_skb in GC.Kuniyuki Iwashima1-3/+4
[ Upstream commit 25236c91b5ab4a26a56ba2e79b8060cf4e047839 ] syzbot reported a task hung; at the same time, GC was looping infinitely in list_for_each_entry_safe() for OOB skb. [0] syzbot demonstrated that the list_for_each_entry_safe() was not actually safe in this case. A single skb could have references for multiple sockets. If we free such a skb in the list_for_each_entry_safe(), the current and next sockets could be unlinked in a single iteration. unix_notinflight() uses list_del_init() to unlink the socket, so the prefetched next socket forms a loop itself and list_for_each_entry_safe() never stops. Here, we must use while() and make sure we always fetch the first socket.

2024-03-06scsi: sd: usb_storage: uas: Access media prior to querying device propertiesMartin K. Petersen4-1/+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.

2024-03-06scsi: core: Add struct for args to execution functionsMike Christie2-41/+62
[ Upstream commit d0949565811f0896c1c7e781ab2ad99d34273fdf ] Move the SCSI execution functions to use a struct for passing in optional args. This commit adds the new struct, temporarily converts scsi_execute() and scsi_execute_req() ands a new helper, scsi_execute_cmd(), which takes the scsi_exec_args struct. There should be no change in behavior. We no longer allow users to pass in any request->rq_flags value, but they were only passing in RQF_PM which we do support by allowing users to pass in the BLK_MQ_REQ flags used by blk_mq_alloc_request(). Subsequent commits will convert scsi_execute() and scsi_execute_req() users to the new helpers then remove scsi_execute() and scsi_execute_req().

2024-03-06drm/meson: Don't remove bridges which are created by other driversMartin Blumenstingl2-2/+0
[ Upstream commit bd915ae73a2d78559b376ad2caf5e4ef51de2455 ] Stop calling drm_bridge_remove() for bridges allocated/managed by other drivers in the remove paths of meson_encoder_{cvbs,dsi,hdmi}. drm_bridge_remove() unregisters the bridge so it cannot be used anymore. Doing so for bridges we don't own can lead to the video pipeline not being able to come up after -EPROBE_DEFER of the VPU because we're unregistering a bridge that's managed by another driver. The other driver doesn't know that we have unregistered it's bridge and on subsequent .probe() we're not able to find those bridges anymore (since nobody re-creates them). This fixes probe errors on Meson8b boards with the CVBS outputs enabled.

2024-03-01arp: Prevent overflow in arp_req_get().Kuniyuki Iwashima1-1/+2
commit a7d6027790acea24446ddd6632d394096c0f4667 upstream. syzkaller reported an overflown write in arp_req_get(). [0] When ioctl(SIOCGARP) is issued, arp_req_get() looks up an neighbour entry and copies neigh->ha to struct arpreq.arp_ha.sa_data. The arp_ha here is struct sockaddr, not struct sockaddr_storage, so the sa_data buffer is just 14 bytes. In the splat below, 2 bytes are overflown to the next int field, arp_flags. We initialise the field just after the memcpy(), so it's not a problem. However, when dev->addr_len is greater than 22 (e.g. MAX_ADDR_LEN), arp_netmask is overwritten, which could be set as htonl(0xFFFFFFFFUL) in arp_ioctl() before calling arp_req_get(). To avoid the overflow, let's limit the max length of memcpy(). Note that commit b5f0de6df6dc ("net: dev: Convert sa_data to flexible array in struct sockaddr") just silenced syzkaller.

commit 51af8f255bdaca6d501afc0d085b808f67b44d91 upstream. ASMedia have confirmed that all ASM106x parts currently listed in ahci_pci_tbl[] suffer from the 43-bit DMA address limitation that we ran into on the ASM1061, and therefore, we need to apply the quirk added by commit 20730e9b2778 ("ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers") to the other supported ASM106x parts as well.

commit 84c531f54ad9a124a924c9505d74e33d16965146 upstream. This patch adds the ability to send RM_ADDR for local ID 0. Check whether id 0 address is removed, if not, put id 0 into a removing list, pass it to mptcp_pm_remove_addr() to remove id 0 address. There is no reason not to allow the userspace to remove the initial address (ID 0). This special case was not taken into account not letting the userspace to delete all addresses as announced.

2024-03-01mm: zswap: fix missing folio cleanup in writeback race pathYosry Ahmed1-0/+2
commit e3b63e966cac0bf78aaa1efede1827a252815a1d upstream. In zswap_writeback_entry(), after we get a folio from __read_swap_cache_async(), we grab the tree lock again to check that the swap entry was not invalidated and recycled. If it was, we delete the folio we just added to the swap cache and exit. However, __read_swap_cache_async() returns the folio locked when it is newly allocated, which is always true for this path, and the folio is ref'd. Make sure to unlock and put the folio before returning. This was discovered by code inspection, probably because this path handles a race condition that should not happen often, and the bug would not crash the system, it will only strand the folio indefinitely.

2024-03-01mm/damon/reclaim: fix quota stauts loss due to online tuningsSeongJae Park1-1/+17
commit 1b0ca4e4ff10a2c8402e2cf70132c683e1c772e4 upstream. Patch series "mm/damon: fix quota status loss due to online tunings". DAMON_RECLAIM and DAMON_LRU_SORT is not preserving internal quota status when applying new user parameters, and hence could cause temporal quota accuracy degradation. Fix it by preserving the status. This patch (of 2): For online parameters change, DAMON_RECLAIM creates new scheme based on latest values of the parameters and replaces the old scheme with the new one. When creating it, the internal status of the quota of the old scheme is not preserved. As a result, charging of the quota starts from zero after the online tuning. The data that collected to estimate the throughput of the scheme's action is also reset, and therefore the estimation should start from the scratch again. Because the throughput estimation is being used to convert the time quota to the effective size quota, this could result in temporal time quota inaccuracy. It would be recovered over time, though. In short, the quota accuracy could be temporarily degraded after online parameters update. Fix the problem by checking the case and copying the internal fields for the status.

2024-03-01erofs: fix inconsistent per-file compression formatGao Xiang2-11/+14
commit 118a8cf504d7dfa519562d000f423ee3ca75d2c4 upstream. EROFS can select compression algorithms on a per-file basis, and each per-file compression algorithm needs to be marked in the on-disk superblock for initialization. However, syzkaller can generate inconsistent crafted images that use an unsupported algorithmtype for specific inodes, e.g. use MicroLZMA algorithmtype even it's not set in `sbi->available_compr_algs`. This can lead to an unexpected "BUG: kernel NULL pointer dereference" if the corresponding decompressor isn't built-in. Fix this by checking against `sbi->available_compr_algs` for each m_algorithmformat request. Incorrect !erofs_sb_has_compr_cfgs preset bitmap is now fixed together since it was harmless previously.

2024-03-01drm/syncobj: call drm_syncobj_fence_add_wait when WAIT_AVAILABLE flag is setErik Kurzinger1-2/+4
[ Upstream commit 3c43177ffb54ea5be97505eb8e2690e99ac96bc9 ] When waiting for a syncobj timeline point whose fence has not yet been submitted with the WAIT_FOR_SUBMIT flag, a callback is registered using drm_syncobj_fence_add_wait and the thread is put to sleep until the timeout expires. If the fence is submitted before then, drm_syncobj_add_point will wake up the sleeping thread immediately which will proceed to wait for the fence to be signaled. However, if the WAIT_AVAILABLE flag is used instead, drm_syncobj_fence_add_wait won't get called, meaning the waiting thread will always sleep for the full timeout duration, even if the fence gets submitted earlier. If it turns out that the fence *has* been submitted by the time it eventually wakes up, it will still indicate to userspace that the wait completed successfully (it won't return -ETIME), but it will have taken much longer than it should have. To fix this, we must call drm_syncobj_fence_add_wait if *either* the WAIT_FOR_SUBMIT flag or the WAIT_AVAILABLE flag is set. The only difference being that with WAIT_FOR_SUBMIT we will also wait for the fence to be signaled after it has been submitted while with WAIT_AVAILABLE we will return immediately.

[ Upstream commit 3489182b11d35f1944c1245fc9c4867cf622c50f ] Commit bb726b753f75 ("net: phy: realtek: add support for RTL8211F(D)(I)-VD-CG") extended support of the driver from the existing support for RTL8211F(D)(I)-CG PHY to the newer RTL8211F(D)(I)-VD-CG PHY. While that commit indicated that the RTL8211F_PHYCR2 register is not supported by the "VD-CG" PHY model and therefore updated the corresponding section in rtl8211f_config_init() to be invoked conditionally, the call to "genphy_soft_reset()" was left as-is, when it should have also been invoked conditionally. This is because the call to "genphy_soft_reset()" was first introduced by the commit 0a4355c2b7f8 ("net: phy: realtek: add dt property to disable CLKOUT clock") since the RTL8211F guide indicates that a PHY reset should be issued after setting bits in the PHYCR2 register. As the PHYCR2 register is not applicable to the "VD-CG" PHY model, fix the rtl8211f_config_init() function by invoking "genphy_soft_reset()" conditionally based on the presence of the "PHYCR2" register.

[ Upstream commit 603ead96582d85903baec2d55f021b8dac5c25d2 ] Both registers used when doing manual injection or fdma injection are shared between all the net devices of the switch. It was noticed that when having two process which each of them trying to inject frames on different ethernet ports, that the HW started to behave strange, by sending out more frames then expected. When doing fdma injection it is required to set the frame in the DCB and then make sure that the next pointer of the last DCB is invalid. But because there is no locks for this, then easily this pointer between the DCB can be broken and then it would create a loop of DCBs. And that means that the HW will continuously transmit these frames in a loop. Until the SW will break this loop. Therefore to fix this issue, add a spin lock for when accessing the registers for manual or fdma injection.

Add the same record type check, and make it unlikely to not penalize the async fastpath.

[ Upstream commit 4cd12c6065dfcdeba10f49949bffcf383b3952d8 ] syzbot reported the following NULL pointer dereference issue [1]: BUG: kernel NULL pointer dereference, address: 0000000000000000 [...] RIP: 0010:0x0 [...] Call Trace: <TASK> sk_psock_verdict_data_ready+0x232/0x340 net/core/skmsg.c:1230 unix_stream_sendmsg+0x9b4/0x1230 net/unix/af_unix.c:2293 sock_sendmsg_nosec net/socket.c:730 [inline] __sock_sendmsg+0x221/0x270 net/socket.c:745 ____sys_sendmsg+0x525/0x7d0 net/socket.c:2584 ___sys_sendmsg net/socket.c:2638 [inline] __sys_sendmsg+0x2b0/0x3a0 net/socket.c:2667 do_syscall_64+0xf9/0x240 entry_SYSCALL_64_after_hwframe+0x6f/0x77 If sk_psock_verdict_data_ready() and sk_psock_stop_verdict() are called concurrently, psock->saved_data_ready can be NULL, causing the above issue. This patch fixes this issue by calling the appropriate data ready function using the sk_psock_data_ready() helper and protecting it from concurrency with sk->sk_callback_lock.

2024-03-01s390: use the correct count for __iowrite64_copy()Jason Gunthorpe1-1/+1
[ Upstream commit 723a2cc8d69d4342b47dfddbfe6c19f1b135f09b ] The signature for __iowrite64_copy() requires the number of 64 bit quantities, not bytes. Multiple by 8 to get to a byte length before invoking zpci_memcpy_toio() Fixes: 87bc359b9822 ("s390/pci: speed up __iowrite64_copy by using pci store block insn") Acked-by: Niklas Schnelle <schnelle@linux.ibm.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Link: https://lore.kernel.org/r/0-v1-9223d11a7662+1d7785-s390_iowrite64_jgg@nvidia.com Signed-off-by: Heiko Carstens <hca@linux.ibm.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
2024-03-01octeontx2-af: Consider the action set by PFSubbaraya Sundeep1-0/+4
[ Upstream commit 3b1ae9b71c2a97f848b00fb085a2bd29bddbe8d9 ] AF reserves MCAM entries for each PF, VF present in the system and populates the entry with DMAC and action with default RSS so that basic packet I/O works. Since PF/VF is not aware of the RSS action installed by AF, AF only fixup the actions of the rules installed by PF/VF with corresponding default RSS action. This worked well for rules installed by PF/VF for features like RX VLAN offload and DMAC filters but rules involving action like drop/forward to queue are also getting modified by AF. Hence fix it by setting the default RSS action only if requested by PF/VF.
