killable riscv architectures relying on mmap_sem for write in their arch_setup_additional_pages. If the waiting task gets killed by the oom killer it would block oom_reaper from asynchronous address space reclaim and reduce the chances of timely OOM resolving.

2021-10-02cachefiles: Fix oops in trace_cachefiles_mark_buried due to NULL objectDave Wysochanski
In cachefiles_mark_object_buried, the dentry in question may not have an owner, and thus our cachefiles_object pointer may be NULL when calling the tracepoint, in which case we will also not have a valid debug_id to print in the tracepoint. Check for NULL object in the tracepoint and if so, just set debug_id to MAX_UINT as was done in 2908f5e101e3 ("fscache: Add a cookie debug ID and use that in traces").

Kernel fails to boot if conntrack is builtin and kernel is booted with: nf_conntrack.enable_hooks=1. From Florian Westphal. 2) Rule event notification is missing relevant context such as the position handle and the NLM_F_APPEND flag. 3) Rule replacement is expanded to add + delete using the existing rule handle, reverse order of this operation so it makes sense from rule notification standpoint. 4) Propagate to userspace the NLM_F_CREATE and NLM_F_EXCL flags from the rule notification path. Patches #2, #3 and #4 are used by 'nft monitor' and 'iptables-monitor' userspace utilities which are not correctly representing the following operations through netlink notifications: - rule insertions - rule addition/insertion from position handle - create table/chain/set/map/flowtable/... ==================== Signed-off-by: David S.

2021-10-01net: mscc: ocelot: fix VCAP filters remaining active after being deletedVladimir Oltean
When ocelot_flower.c calls ocelot_vcap_filter_add(), the filter has a given filter->id.cookie. This filter is added to the block->rules list. However, when ocelot_flower.c calls ocelot_vcap_block_find_filter_by_id() which passes the cookie as argument, the filter is never found by filter->id.cookie when searching through the block->rules list. This is unsurprising, since the filter->id.cookie is an unsigned long, but the cookie argument provided to ocelot_vcap_block_find_filter_by_id() is a signed int, and the comparison fails.

Rui will continue to review patches in that area. The thermal development process flow will change so that the material from the thermal git tree will be merged into the thermal branch of the linux-pm.git tree before going into the mainline.

We have never supported fasync properly, it would only fire when there is something polling io_uring making it useless. The original support came in through the initial io_uring merge for 5.1.

2021-10-01SUNRPC: fix sign error causing rpcsec_gss dropsJ. Bruce Fields
If sd_max is unsigned, then sd_max - GSS_SEQ_WIN is a very large number whenever sd_max is less than GSS_SEQ_WIN, and the comparison: seq_num <= sd->sd_max - GSS_SEQ_WIN in gss_check_seq_num is pretty much always true, even when that's clearly not what was intended. This was causing pynfs to hang when using krb5, because pynfs uses zero as the initial gss sequence number. That's perfectly legal, but this logic error causes knfsd to drop the rpc in that case. Out-of-order sequence IDs in the first GSS_SEQ_WIN (128) calls will also cause this.
