找到弃用的syscall的原因

我是新手＆amp;在这里我的元素，但我需要知道一些事情：

仔细阅读journalctl输出时，以下行反复出现了一段时间，然后在某个时间点之后，它停止出现：

...内核：ICMPV6：Process'DHCPCD'使用已弃用的sysctl（syscall）net.ipv6.neigh.wlan0.retrans_time-使用net.ipv6.neigh.wlan0.wlan0.retrans_time_ms代替

ines 客户端我的（Raspberry Pi OS）系统。我得出的结论（可能是错误的），此弃用syscall是在dhcpcd源代码中专门调用的。为了找到该代码，我尝试了这一点：

$ grep -Ril 'net.ipv6.neigh.wlan0.retrans_time' ~/dhcpcd5 
$ # where ~/dhcpcd5 is the 'source package' fetched fm the RPi archives

不幸的是，这一无所获 - 没有匹配。我如何学习在哪里＆amp; dhcpcd如何使用现在被剥夺的syscall？这是我系统内核过时的结果吗？

原文

I am a rank newbie & out of my element here, but I need to know something:

While perusing journalctl output, the following line appeared repeatedly for a time, and then, after a point in time, it stopped appearing:

... kernel: ICMPv6: process 'dhcpcd' is using deprecated sysctl (syscall) net.ipv6.neigh.wlan0.retrans_time - use net.ipv6.neigh.wlan0.retrans_time_ms instead

dhcpcd is the DHCP client daemon for my (Raspberry Pi OS) system. I concluded (probably incorrectly) that this deprecated syscall was something called out specifically in the dhcpcd source code. In an effort to find that code, I tried this:

$ grep -Ril 'net.ipv6.neigh.wlan0.retrans_time' ~/dhcpcd5 
$ # where ~/dhcpcd5 is the 'source package' fetched fm the RPi archives

Unfortunately, this yielded nothing - no match. How do I learn where & how dhcpcd came to use this now-deprecated syscall? Is this the result of my system's kernel being out-of-date - or what?
