Hi there!
Has anyone looked at getting OpenAFS working on FreeBSD 14.1 lately?
They've changed a bunch of stuff. I managed to get it to compile, and I can
load the kernel module and start bosserver, but as soon as I run bos setcell, I
get a kernel panic. In fact, any command which takes a -server argument causes
a panic.
Here's a backtrace from a dump:
First of all, the stack backtrace while starting kgdb:
...
KDB: stack backtrace:
#0 0xffffffff80b7fbfd at kdb_backtrace+0x5d
#1 0xffffffff80b32961 at vpanic+0x131

#8 0xffffffff8100073b at amd64_syscall+0x67b
#9 0xffffffff80fd735b at fast_syscall_common+0xf8
...
And the backtrace:
(kgdb) backtrace

#9 0x0000000000000000 in ?? ()
rxi_FindIfnet is in src/rx/rx_kcommon.c. One thing that I noticed that jumps
out at me is that on FreeBSD, the code calls CURVNET_SET. This same call and
some similar ones are also present in a section of src/afs/afs_server.c that
needed some changes due to removed calls in FreeBSD 14.1.
However, I'm much less familiar with FreeBSD than I am with AIX, so I would
appreciate a pointer if I'm looking in the right direction or this is a red
herring.
Debugging on this version of FreeBSD is also made more difficult as trying to
build the OpenAFS tree with debug enabled results in many errors similar to
this:
usr/bin/ctfconvert -g -l openafs .libs/camellia.o ERROR: ctfconvert: rc = 1
Unsupported version [_dwarf_info_load(229)]
As always, many thanks in advance for any tips/pointers!
