Notes for BIND 9.18.25
|
|
----------------------
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- A regression in cache-cleaning code enabled memory use to grow
|
|
significantly more quickly than before, until the configured
|
|
:any:`max-cache-size` limit was reached. This has been fixed.
|
|
:gl:`#4596`
|
|
|
|
- Using :option:`rndc flush` inadvertently caused cache cleaning to
|
|
become less effective. This could ultimately lead to the configured
|
|
:any:`max-cache-size` limit being exceeded and has now been fixed.
|
|
:gl:`#4621`
|
|
|
|
- The logic for cleaning up expired cached DNS records was
|
|
tweaked to be more aggressive. This change helps with enforcing
|
|
:any:`max-cache-ttl` and :any:`max-ncache-ttl` in a timely manner.
|
|
:gl:`#4591`
|
|
|
|
- It was possible to trigger a use-after-free assertion when the overmem cache
|
|
cleaning was initiated. This has been fixed. :gl:`#4595`
|
|
|
|
ISC would like to thank Jinmei Tatuya of Infoblox for bringing
|
|
this issue to our attention.
