Hi!
I just built a new LFS 8.3 system and everything seemed to work well at
a first glance. But when trying to install DHCP-4.4.1 according to BLFS
8.3 stable
(/http://www.linuxfromscratch.org/blfs/view/stable/basicnet/dhcp.html/)
the build aborts due to errors (please see the output below).
First warnings appear during the build of the bind libraries ("/In file
included from entropy.c:61: ../entropy.c: In function
'entropypool_adddata': ../entropy.c:327:7: warning: this statement may
fall through [-Wimplicit-fallthrough=] len--;/" and finally the build
breaks.
I also recognized that during startup of the machine I get multiple
errors like:
/[ 5.580768] random: udevd: uninitialized urandom read (16 bytes read)/
/[ 7.752273] random: sshd: uninitialized urandom read (32 bytes read)
/and finally:/
[ 44.233105] random: crng init done
/
Might it be, that the broken DHCP build is due to some failure of the
random generator as the first warning seems be related to entropy? But I
am not not sure, if the random generator is broken at all. How could I
figure out the core of the build issue?
At least the random and urandom devices exist:
/# ls -la /dev/*rand*//
//crw-rw-rw- 1 root root 1, 8 Dec 18 19:09 /dev/random//
//crw-rw-rw- 1 root root 1, 9 Dec 18 19:09 /dev/urandom/
I tried with kernels 4.18.14 and 4.18.5.
I also tried DHCP-4.3.5 but it fails in a similar manner.
Building other packages (e.g. zip, unzip, openssh) works flawlessly.
I also tried to build DHCP-4.4.1 on an older BLFS 6.8 and it built
flawlessly.
My system is running on VMware and I build several other LFS/BLFS
systems before and there never was an issue with random or DHCP.
By the way: The BLFS book suggests for DHCP to use the "/missing_ipv6/"
patch if the kernel has no IPv6 support. As I could not find this patch
in /http://www.linuxfromscratch.org/patches/blfs/8.3//, I had to compile
IPv6 into the kernel. Is there no such patch anymore available for BLFS 8.3?
Any help would be highly appreciated.
Regards
Alexander
