A unlock will allocate a\n\"struct plock_op\" and a followed send_op() will append it to a global\nsend_list data structure. In some cases a followed dev_read() moves it\nto recv_list and dev_write() will cast it to \"struct plock_xop\" and access\nfields which are only available in those structures. At this point an\ninvalid read happens by accessing those fields.\nTo fix this issue the \"callback\" field is moved to \"struct plock_op\" to\nindicate that a cast to \"plock_xop\" is allowed and does the additional\n\"plock_xop\" handling if set.\nExample of the KASAN output which showed the invalid read:\n[ 2064.296453] ==================================================================\n[ 2064.304852] BUG: KASAN: slab-out-of-bounds in dev_write+0x52b/0x5a0 [dlm]\n[ 2064.306491] Read of size 8 at addr ffff88800ef227d8 by task dlm_controld/7484\n[ 2064.308168]\n[ 2064.308575] CPU: 0 PID: 7484 Comm: dlm_controld Kdump: loaded Not tainted 5.14.0+ #9\n[ 2064.310292] Hardware name: Red Hat KVM, BIOS 0.5.1 01/01/2011\n[ 2064.311618] Call Trace:\n[ 2064.312218] dump_stack_lvl+0x56/0x7b\n[ 2064.313150] print_address_description.constprop.8+0x21/0x150\n[ 2064.314578] ?
