net/ipv4: ping_group_range: allow GID from 2147483648 to 4294967294
[ Upstream commit e209fee4118fe9a449d4d805361eb2de6796be39 ]
With this commit, all the GIDs ("0 4294967294") can be written to the
"net.ipv4.ping_group_range" sysctl.
Note that 4294967295 (0xffffffff) is an invalid GID (see gid_valid() in
include/linux/uidgid.h), and an attempt to register this number will cause
-EINVAL.
Prior to this commit, only up to GID 2147483647 could be covered.
Documentation/networking/ip-sysctl.rst had "0 4294967295" as an example
value, but this example was wrong and causing -EINVAL.
Fixes: c319b4d76b9e ("net: ipv4: add IPPROTO_ICMP socket kind")
