Hello Rick Edgecombe,
Commit 211f514ebf1e ("Drivers: hv: vmbus: Track decrypted status in
vmbus_gpadl") from Mar 11, 2024 (linux-next), leads to the following
Smatch static checker warning:
drivers/hv/channel.c:870 vmbus_teardown_gpadl()
warn: assigning signed to unsigned: 'gpadl->decrypted = ret'
's32min-s32max'
drivers/hv/channel.c
860 list_del(&info->msglistentry);
861 spin_unlock_irqrestore(&vmbus_connection.channelmsg_lock,
flags);
862
863 kfree(info);
864
865 ret = set_memory_encrypted((unsigned long)gpadl->buffer,
866 PFN_UP(gpadl->size));
867 if (ret)
868 pr_warn("Fail to set mem host visibility in GPADL
teardown %d.\n", ret);
869
--> 870 gpadl->decrypted = ret;
ret is error codes but ->decrypted is bool. So error codes mean decrypted is
true.
871
872 return ret;
873 }
