Subject: [PATCH net-next 0/2] net: visibility of memory limits in netns
Some programs need to know the size of the network buffers to operate
correctly, export the following sysctls read-only in network namespaces:
- net.core.rmem_default
- net.core.rmem_max
- net.core.wmem_default
- net.core.wmem_max
Matteo Croce (2):
net: make net.core.{r,w}mem_{default,max} namespaced
selftests: net: tests net.core.{r,w}mem_{default,max} sysctls in a
netns
