Travis Rhoden	beefa56cb8	Remove pkg/util/mount (moved out of tree) This patch removes pkg/util/mount completely, and replaces it with the mount package now located at k8s.io/utils/mount. The code found at k8s.io/utils/mount was moved there from pkg/util/mount, so the code is identical, just no longer in-tree to k/k.

Mike Danese	ad9759b203	Add an expiring cache for the caching token authenticator And maybe the webhook authorizer cache. This cache has two primary advantages over the LRU cache used currently: - Cache hits don't acquire an exclusive lock. - More importantly, performance doesn't fallover when the access pattern scans a key space larger than an arbitrary size (e.g. the LRU capacity). The downside of using an expiring cache here is that it doesn't have a maximum size so it's suspectible to DoS when the input is user controlled. This is not the case for successful authentications, and successful authentications have a natural expiry so it might be a good fit here. It has some a few differences compared to: https://github.com/kubernetes/kubernetes/blob/3d7318f29d9f56810efd3d690811cdea730b5317/staging/src/k8s.io/client-go/tools/cache/expiration_cache.go - Expiration is not entirely lazy so keys that are never accessed again are still released from the cache. - It does not acquire an exclusive lock on cache hits. - It supports per entry ttls specified on Set. The expiring cache (without striping) does somewhere in between the simple cache and striped cache in the very contrived contention test where every iteration acquires a write lock: ``` $ benchstat simple.log expiring.log name old time/op new time/op delta Cache-12 2.74µs ± 2% 2.02µs ± 3% -26.37% (p=0.000 n=9+9) name old alloc/op new alloc/op delta Cache-12 182B ± 0% 107B ± 4% -41.21% (p=0.000 n=8+9) name old allocs/op new allocs/op delta Cache-12 5.00 ± 0% 2.00 ± 0% -60.00% (p=0.000 n=10+10) $ benchstat striped.log expiring.log name old time/op new time/op delta Cache-12 1.58µs ± 5% 2.02µs ± 3% +27.34% (p=0.000 n=10+9) name old alloc/op new alloc/op delta Cache-12 288B ± 0% 107B ± 4% -62.85% (p=0.000 n=10+9) name old allocs/op new allocs/op delta Cache-12 9.00 ± 0% 2.00 ± 0% -77.78% (p=0.000 n=10+10) $ benchstat simple.log striped.log expiring.log name \ time/op simple.log striped.log expiring.log Cache-12 2.74µs ± 2% 1.58µs ± 5% 2.02µs ± 3% name \ alloc/op simple.log striped.log expiring.log Cache-12 182B ± 0% 288B ± 0% 107B ± 4% name \ allocs/op simple.log striped.log expiring.log Cache-12 5.00 ± 0% 9.00 ± 0% 2.00 ± 0% ``` I also naively replacemed the LRU cache with the expiring cache in the more realisitc CachedTokenAuthenticator benchmarks: https://gist.github.com/mikedanese/41192b6eb62106c0758a4f4885bdad53 For token counts that fit in the LRU, expiring cache does better because it does not require acquiring an exclusive lock for cache hits. For token counts that exceed the size of the LRU, the LRU has a massive performance drop off. The LRU cache is around 5x slower (with lookups taking 1 milisecond and throttled to max 40 lookups in flight). ``` $ benchstat before.log after.log name old time/op new time/op delta CachedTokenAuthenticator/tokens=100_threads=256-12 3.60µs ±22% 1.08µs ± 4% -69.91% (p=0.000 n=10+10) CachedTokenAuthenticator/tokens=500_threads=256-12 3.94µs ±19% 1.20µs ± 3% -69.57% (p=0.000 n=10+10) CachedTokenAuthenticator/tokens=2500_threads=256-12 3.07µs ± 6% 1.17µs ± 1% -61.87% (p=0.000 n=9+10) CachedTokenAuthenticator/tokens=12500_threads=256-12 3.16µs ±17% 1.38µs ± 1% -56.23% (p=0.000 n=10+10) CachedTokenAuthenticator/tokens=62500_threads=256-12 15.0µs ± 1% 2.9µs ± 3% -80.71% (p=0.000 n=10+10) name old alloc/op new alloc/op delta CachedTokenAuthenticator/tokens=100_threads=256-12 337B ± 1% 300B ± 0% -11.06% (p=0.000 n=10+8) CachedTokenAuthenticator/tokens=500_threads=256-12 307B ± 1% 304B ± 0% -0.96% (p=0.000 n=9+10) CachedTokenAuthenticator/tokens=2500_threads=256-12 337B ± 1% 304B ± 0% -9.79% (p=0.000 n=10+10) CachedTokenAuthenticator/tokens=12500_threads=256-12 343B ± 1% 276B ± 0% -19.58% (p=0.000 n=10+10) CachedTokenAuthenticator/tokens=62500_threads=256-12 493B ± 0% 334B ± 0% -32.12% (p=0.000 n=10+10) name old allocs/op new allocs/op delta CachedTokenAuthenticator/tokens=100_threads=256-12 13.0 ± 0% 11.0 ± 0% -15.38% (p=0.000 n=10+10) CachedTokenAuthenticator/tokens=500_threads=256-12 12.0 ± 0% 11.0 ± 0% -8.33% (p=0.000 n=10+10) CachedTokenAuthenticator/tokens=2500_threads=256-12 13.0 ± 0% 11.0 ± 0% -15.38% (p=0.000 n=10+10) CachedTokenAuthenticator/tokens=12500_threads=256-12 13.0 ± 0% 10.0 ± 0% -23.08% (p=0.000 n=9+10) CachedTokenAuthenticator/tokens=62500_threads=256-12 17.0 ± 0% 12.0 ± 0% -29.41% (p=0.000 n=10+10) ``` Benchmarked with changes in #84423 Bugs: #83259 #83375 Kubernetes-commit: 9167711fd18511ffc9c90ee306c462be9fc7999b	2019-10-26 12:19:07 -07:00
