It makes use of "page_mapcount(webpage)" to decide if a COW page must be NUMA-shielded or not, and which makes Completely no perception. the volume of mappings a site has is irrelevant: not simply does GUP get yourself a reference to some page as in Oded's scenario, but the other mappings migth be paged out and the only reference to them might be from the web page rely. considering that we should always by no means try and NUMA-harmony a web page that we will not shift anyway on account of other references, just take care of the code to work with 'page_count()'. Oded confirms that that fixes his situation. Now, this does imply that anything in NUMA balancing finally ends up shifting webpage protections (apart from the obvious certainly one of making the site inaccessible to have the NUMA faulting info). usually the COW simplification would not make any difference - since performing the GUP to the site would ensure it's writable. The cause of that permission improve could be good to determine also, because it Obviously results in spurious COW occasions - but repairing the nonsensical examination that just took place to work in advance of is obviously the CorrectThing(tm) to try and do No matter.
This month, the following corporations managed to provide An impressive service and guidance. It can be value taking a look.
inside the Linux kernel, the next vulnerability has been resolved: net: take care of a memleak when uncloning an skb dst and its metadata When uncloning an skb dst and its linked metadata, a fresh dst+metadata is allotted and later on replaces the outdated 1 in the skb. This is useful to possess a non-shared dst+metadata attached to a selected skb. The difficulty would be the uncloned dst+metadata is initialized with a refcount of 1, which happens to be improved to 2 before attaching it on the skb.

In the Linux kernel, the subsequent vulnerability has become solved: Internet/mlx5: resolve a race on command flush stream deal with a refcount use following cost-free warning as a result of a race on command entry. this sort of race happens when one of the instructions releases its past refcount and frees its index and entry even though A further process operating command flush movement can take refcount to this command entry. The process which handles commands flush may even see this command as required to be flushed if the opposite process unveiled its refcount but failed to launch the index but.
