Hagar Hemdan b97e8a2f71 irqchip/gic-v3-its: Fix potential race condition in its_vlpi_prop_update() ... its_vlpi_prop_update() calls lpi_write_config() which obtains the mapping information for a VLPI without lock held. So it could race with its_vlpi_unmap(). Since all calls from its_irq_set_vcpu_affinity() require the same lock to be held, hoist the locking there instead of sprinkling the locking all over the place. This bug was discovered using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc. [ tglx: Use guard() instead of goto ] Fixes: 015ec0386a ("irqchip/gic-v3-its: Add VLPI configuration handling") Suggested-by: Marc Zyngier <maz@kernel.org> Signed-off-by: Hagar Hemdan <hagarhem@amazon.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: stable@vger.kernel.org Reviewed-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20240531162144.28650-1-hagarhem@amazon.com		2024-06-03 18:20:00 +02:00
