      encoding/gob: error out instead of panicking on nil dereference · 0a2a64d8
      Emmanuel Odeke authored 
      Do not panic when we encounter nil interface values which are
invalid values for gob. Previously this wasn't caught yet
we were calling reflect.*.Type() on reflect.Invalid values
thereby causing panic:
  `panic: reflect: call of reflect.Value.Type on zero Value.`
which is a panic not enforced by encoding/gob itself.
We can catch this and send back an error to the caller.

Fixes #16204

      runtime: increase malloc size classes · 14e59511
      Dmitry Vyukov authored 
      When we calculate class sizes, in some cases we discard considerable
amounts of memory without an apparent reason. For example, we choose
size 8448 with 6 objects in 7 pages. But we can well use object
size 9472, which is also 6 objects in 7 pages but +1024 bytes (+12.12%).

Increase class sizes to the max value that leads to the same
page count/number of objects. Full list of affected size classes:

class 36: pages: 2 size: 1664->1792 +128 (7.69%)
class 39: pages: 1 size: 2560->2688 +128 (5.0%)
class 40: pages: 3 size: 2816->3072 +256 (9.9%)
class 41: pages: 2 size: 3072->3200 +128 (4.16%)
class 42: pages: 3 size: 3328->3456 +128 (3.84%)
class 44: pages: 3 size: 4608->4864 +256 (5.55%)
class 47: pages: 4 size: 6400->6528 +128 (2.0%)
class 48: pages: 5 size: 6656->6784 +128 (1.92%)
class 51: pages: 7 size: 8448->9472 +1024 (12.12%)
class 52: pages: 6 size: 8704->9728 +1024 (11.76%)
class 53: pages: 5 size: 9472->10240 +768 (8.10%)
class 54: pages: 4 size: 10496->10880 +384 (3.65%)
class 57: pages: 7 size: 14080->14336 +256 (1.81%)
class 59: pages: 9 size: 16640->18432 +1792 (10.76%)
class 60: pages: 7 size: 17664->19072 +1408 (7.97%)

      runtime: fix check for vacuous page boundary rounding again · 3de7dbb1
      Austin Clements authored 
      The previous fix for this, commit 336dad2a, had everything right in
the commit message, but reversed the test in the code. Fix the test in
the code.

This reversal effectively disabled the scavenger on large page systems
*except* in the rare cases where this code was originally wrong, which
is why it didn't obviously show up in testing.

Fixes #16644. Again. :(
