alpine 3.13 在 Armhf docker 的网络问题

IT, 其他

最近在编译最新的 qBittorrent 4.3.3 时,我在 Armhf 平台上遇到了这样的问题,在我拉取最新的 alpine 并且进行更新时遇到了如下的报错:


fetch https://dl-cdn.alpinelinux.org/alpine/v3.13/main/armv7/APKINDEX.tar.gz
3069375376:error:0D0D90AD:asn1 encoding routines:ASN1_TIME_adj:error getting time:crypto/asn1/a_time.c:330:

WARNING: Ignoring https://dl-cdn.alpinelinux.org/alpine/v3.13/community: No such file or directory
2 errors; 14 distinct packages available

并且可以发现:


/ # ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
ping: clock_gettime(MONOTONIC) failed

这是由于系统时间不正确造成的。

原因

这是因为 Alpine 3.13 版本中 musl 的版本被升级了,它改变了 time_t 在 32位系统中的定义。它会使用一个新的兼容 time64 的 system call。因此就需要将 Docker 版本升级到 19.03.9,或者宿主的 libseccomp 版本升级到 2.4.2。我目前使用的 Docker 官方 ppa 种还没有最新的 armhf 使用的 Docker 因此在这里就会引起错误的系统调用,无法获取正确的外部时间。

修复

目前可以通过 moby 的补丁修复,修复方法如下:
