As far as I can tell, there\u0027s no reason for the mutex to be\nheld while the gadget core calls a gadget driver\u0027s -\u003ebind or -\u003eunbind\nroutine, or while a UDC is being started or stopped.  (This accounts\nfor link #1 in the chain above, where the mutex is held while the\ndwc2_hsotg_udc is started as part of driver probing.)\n\nGadget drivers\u0027 -\u003edisconnect callbacks are problematic.  Even though\nusb_gadget_disconnect() will now acquire the udc_mutex, there\u0027s a\nwindow in usb_gadget_bind_driver() between the times when the mutex is\nreleased and the -\u003ebind callback is invoked.  If a disconnect occurred\nduring that window, we could call the driver\u0027s -\u003edisconnect routine\nbefore its -\u003ebind routine.  To prevent this from happening, it will be\nnecessary to prevent a UDC from connecting while it has no gadget\ndriver.  This should be done already but it doesn\u0027t seem to be;\ncurrently usb_gadget_connect() has no check for this.  Such a check\nwill have to be added later.\n\nSome degree of mutual exclusion is required in soft_connect_store(),\nwhich can dereference udc-\u003edriver at arbitrary times since it is a\nsysfs callback.  The solution here is to acquire the gadget\u0027s device\nlock rather than the udc_mutex.  Since the driver core guarantees that\nthe device lock is always held during driver binding and unbinding,\nthis will make the accesses in soft_connect_store() mutually exclusive\nwith any changes to udc-\u003edriver.\n\nLastly, it turns out there is one place which should hold the\nudc_mutex but currently does not: The function_show() routine needs\nprotection while it dereferences udc-\u003edriver.  The missing lock and\nunlock calls are added."

However a later commit 7a3a401874be\n(\"x86/tdx: Drop flags from __tdx_hypercall()\") removed that \"pop %rsi\"\nbut forgot to add the \"xor %rsi, %rsi\" back.\n\nFix by adding it back."

If it\u0027s not the same it means that\nit\u0027s either been invalidated or replaced, in both cases the writeback is\naborted because the local entry contains stale data.\n\nReproducer:\nI originally found this by running `stress` overnight to validate my work\non the zswap writeback mechanism, it manifested after hours on my test\nmachine.  The key to make it happen is having zswap writebacks, so\nwhatever setup pumps /sys/kernel/debug/zswap/written_back_pages should do\nthe trick.\n\nIn order to reproduce this faster on a vm, I setup a system with ~100M of\navailable memory and a 500M swap file, then running `stress --vm 1\n--vm-bytes 300000000 --vm-stride 4000` makes it happen in matter of tens\nof minutes.  One can speed things up even more by swinging\n/sys/module/zswap/parameters/max_pool_percent up and down between, say, 20\nand 1; this makes it reproduce in tens of seconds.  It\u0027s crucial to set\n`--vm-stride` to something other than 4096 otherwise `stress` won\u0027t\nrealize that memory has been corrupted because all pages would have the\nsame data."
