And then after removal from the radix tree the structure wasn't scheduled for freeing. (All structures still left in the radix tree would be freed upon domain destruction, though.) For the freeing to be safe even if it didn't use RCU (i.e. to avoid use- after-free), re-arrange checks/operations in evtchn_close(), such that the pointer wouldn't be used anymore after calling pirq_cleanup_check() (noting that unmap_domain_pirq_emuirq() itself calls the function in the success case). Fixes: c24536b636f2 ("replace d->nr_pirqs sized arrays with radix tree") Fixes: 79858fee307c ("xen: fix hvm_domain_use_pirq's behavior") Signed-off-by: Jan Beulich <jbeulich@xxxxxxxx> Reviewed-by: Roger Pau Monné <roger.pau@xxxxxxxxxx> master commit: daa90dfea9175c07f13d1a2d901857b2dd14d080 master date: 2024-07-02 08:35:56 +0200 For bisection revision-tuple graph see: http://logs.test-lab.xenproject.org/osstest/results/bisect/xen-4.18-testing/build-arm64.xen-build.html Revision IDs in each graph node refer, respectively, to the Trees above. ---------------------------------------- Running cs-bisection-step --graph-out=/home/logs/results/bisect/xen-4.18-testing/build-arm64.xen-build --summary-out=tmp/186689.bisection-summary --basis-template=186514 --blessings=real,real-bisect,real-retry xen-4.18-testing build-arm64 xen-build Searching for failure / basis pass: 186655 fail [host=rochester1] / 186514 ok.
