I believe every feat in the core book is legal, with the exception of Leadership and item crafting feats. For other books, you can check the additional resources guide here.

To begin with, the Core Rulebook is not listed in the Additional Resources page because it's not an additional resource. For information about what's legal in the Core Rulebook, you'd actually have to turn to the Guide to Pathfinder Society Organized Play ( http://paizo.com/products/btpy84k4 ).
Since Deflect Arrows is a feat from the Core Rulebook, and because it is not mentioned anywhere within the Guide, it is legal for play.
Dragon Style, however, is a feat from Ultimate Combat. According to the Additional Resource list, Dragon Style is not a restricted feat:
Ultimate Combat
Feats: The following feats are not allowed in Pathfinder Society Organized Play: Expert Driver, Field Repair, Master Combat Performer, Master Siege Engineer, Performance Weapon Master, Performing Combatant, Secret Stash Deed, Siege Commander, Siege Engineer, Siege Gunner, Skilled Driver,, and all performance feats.
