2022-04-25net/smc: sync err code when tcp connection was refusedliuyacan
In the current implementation, when TCP initiates a connection to an unavailable [ip,port], ECONNREFUSED will be stored in the TCP socket, but SMC will not. However, some apps (like curl) use getsockopt(,,SO_ERROR,,) to get the error information, which makes them miss the error message and behave strangely.

2022-04-25net: hns3: add return value for mailbox handling in PFJian Shen
Currently, there are some querying mailboxes sent from VF to PF, and VF will wait the PF's handling result. For mailbox HCLGE_MBX_GET_QID_IN_PF and HCLGE_MBX_GET_RSS_KEY, it may fail when the input parameter is invalid, but the prototype of their handler function is void. In this case, PF always return success to VF, which may cause the VF get incorrect result. Fixes it by adding return value for these function.

2022-04-25ceph: get snap_rwsem read lock in handle_cap_export for ceph_add_capNiels Dossche
ceph_add_cap says in its function documentation that the caller should hold the read lock on the session snap_rwsem. Furthermore, not only ceph_add_cap needs that lock, when it calls to ceph_lookup_snap_realm it eventually calls ceph_get_snap_realm which states via lockdep that snap_rwsem needs to be held. handle_cap_export calls ceph_add_cap without that mdsc->snap_rwsem held. Thus, since ceph_get_snap_realm and ceph_add_cap both need the lock, the common place to acquire that lock is inside handle_cap_export.

Because some newer hardware variants have multiple possible parents for the RTC's timekeeping clock, this driver models it as a "rtc-32k" clock. However, it does not add any consumer for this clock. This causes the common clock framework to disable it, preventing RTC time access. Since the RTC's timekeeping clock should always be enabled, regardless of which drivers are loaded, let's mark this clock as critical instead of adding a consumer in the RTC driver.

2022-04-24kvmalloc: use vmalloc_huge for vmalloc allocationsLinus Torvalds
Since commit 559089e0a93d ("vmalloc: replace VM_NO_HUGE_VMAP with VM_ALLOW_HUGE_VMAP"), the use of hugepage mappings for vmalloc is an opt-in strategy, because it caused a number of problems that weren't noticed until x86 enabled it too. One of the issues was fixed by Nick Piggin in commit 3b8000ae185c ("mm/vmalloc: huge vmalloc backing pages should be split rather than compound"), but I'm still worried about page protection issues, and VM_FLUSH_RESET_PERMS in particular. However, like the hash table allocation case (commit f2edd118d02d: "page_alloc: use vmalloc_huge for large system hash"), the use of kvmalloc() should be safe from any such games, since the returned pointer might be a SLUB allocation, and as such no user should reasonably be using it in any odd ways. We also know that the allocations are fairly large, since it falls back to the vmalloc case only when a kmalloc() fails. So using a hugepage mapping seems both safe and relevant. This patch does show a weakness in the opt-in strategy: since the opt-in flag is in the 'vm_flags', not the usual gfp_t allocation flags, very few of the usual interfaces actually expose it. That's not much of an issue in this case that already used one of the fairly specialized low-level vmalloc interfaces for the allocation, but for a lot of other vmalloc() users that might want to opt in, it's going to be very inconvenient. We'll either have to fix any compatibility problems, or expose it in the gfp flags (__GFP_COMP would have made a lot of sense) to allow normal vmalloc() users to use hugepage mappings. That said, the cases that really matter were probably already taken care of by the hash tabel allocation.

2022-04-23sctp: check asoc strreset_chunk in sctp_generate_reconf_eventXin Long
A null pointer reference issue can be triggered when the response of a stream reconf request arrives after the timer is triggered, such as: send Incoming SSN Reset Request ---> CPU0: reconf timer is triggered, go to the handler code before hold sk lock <--- reply with Outgoing SSN Reset Request CPU1: process Outgoing SSN Reset Request, and set asoc->strreset_chunk to NULL CPU0: continue the handler code, hold sk lock, and try to hold asoc->strreset_chunk, crash! In Ying Xu's testing, the call trace is: [ ] BUG: kernel NULL pointer dereference, address: 0000000000000010 [ ] RIP: 0010:sctp_chunk_hold+0xe/0x40 [sctp] [ ] Call Trace: [ ] <IRQ> [ ] sctp_sf_send_reconf+0x2c/0x100 [sctp] [ ] sctp_do_sm+0xa4/0x220 [sctp] [ ] sctp_generate_reconf_event+0xbd/0xe0 [sctp] [ ] call_timer_fn+0x26/0x130 This patch is to fix it by returning from the timer handler if asoc strreset_chunk is already set to NULL.
