rxrpc: Fix missing locking causing hanging calls

2024-11-07T19:30:34Z

If a call gets aborted (e.g. because kafs saw a signal) between it being queued for connection and the I/O thread picking up the call, the abort will be prioritised over the connection and it will be removed from local->new_client_calls by rxrpc_disconnect_client_call() without a lock being held. This may cause other calls on the list to disappear if a race occurs. Fix this by taking the client_call_lock when removing a call from whatever list its ->wait_link happens to be on.

afs: Fix missing subdir edit when renamed between parent dirs

2024-10-24T11:50:27Z

When rename moves an AFS subdirectory between parent directories, the subdir also needs a bit of editing: the ".." entry needs updating to point to the new parent (though I don't make use of the info) and the DV needs incrementing by 1 to reflect the change of content. The server also sends a callback break notification on the subdirectory if we have one, but we can take care of recovering the promise next time we access the subdir. This can be triggered by something like: mount -t afs %example.com:xfstest.test20 /xfstest.test/ mkdir /xfstest.test/{aaa,bbb,aaa/ccc} touch /xfstest.test/bbb/ccc/d mv /xfstest.test/{aaa/ccc,bbb/ccc} touch /xfstest.test/bbb/ccc/e When the pathwalk for the second touch hits "ccc", kafs spots that the DV is incorrect and downloads it again (so the fix is not critical). Fix this, if the rename target is a directory and the old and new parents are different, by: (1) Incrementing the DV number of the target locally. (2) Editing the ".." entry in the target to refer to its new parent's vnode ID and uniquifier.

dma-mapping: fix tracing dma_alloc/free with vmalloc'd memory

2024-10-17T15:41:29Z

Not all virtual addresses have physical addresses, such as if they were vmalloc'd. Just trace the virtual address instead of trying to trace a physical address. This aligns with the API, and is good enough to associate dma_alloc with dma_free.

mm: khugepaged: fix the arguments order in khugepaged_collapse_file trace point

2024-10-17T07:28:09Z

The "addr" and "is_shmem" arguments have different order in TP_PROTO and TP_ARGS. This resulted in the incorrect trace result: text-hugepage-644429 [276] 392092.878683: mm_khugepaged_collapse_file: mm=0xffff20025d52c440, hpage_pfn=0x200678c00, index=512, addr=1, is_shmem=0, filename=text-hugepage, nr=512, result=failed The value of "addr" is wrong because it was treated as bool value, the type of is_shmem. Fix the order in TP_PROTO to keep "addr" is before "is_shmem" since the original patch review suggested this order to achieve best packing. And use "lx" for "addr" instead of "ld" in TP_printk because address is typically shown in hex. After the fix, the trace result looks correct: text-hugepage-7291 [004] 128.627251: mm_khugepaged_collapse_file: mm=0xffff0001328f9500, hpage_pfn=0x20016ea00, index=512, addr=0x400000, is_shmem=0, filename=text-hugepage, nr=512, result=failed Link: https://lkml.kernel.org/r/20241012011702.1084846-1-yang@os.amperecomputing.com Fixes: 4c9473e87e75 ("mm/khugepaged: add tracepoint to collapse_file()") Signed-off-by: Yang Shi Cc: Gautam Menghani Cc: Steven Rostedt (Google) Cc: [6.2+] Signed-off-by: Andrew Morton

netfs: In readahead, put the folio refs as soon extracted

2024-10-07T11:48:22Z

netfslib currently defers dropping the ref on the folios it obtains during readahead to after it has started I/O on the basis that we can do it whilst we wait for the I/O to complete, but this runs the risk of the I/O collection racing with this in future. Furthermore, Matthew Wilcox strongly suggests that the refs should be dropped immediately, as readahead_folio() does (netfslib is using __readahead_batch() which doesn't drop the refs).
