nfs-kernel-server: provide a NFSv3 and NFSv4 daemon
Summary:
The current build does not produce an NFSV4 capable package. This commit
fixes that providing a v3 and v4 variant to empower users to have either.
Approx. size differences between v3 and v4:
The v4 variant is approximately 16 MiB larger than the v3 variant
due to additional dependencies, kernel modules, etc.[1]
Detailed changes:
1. Split into a v3 and v4 version series of packages. In doing
this, the build-time V4 options are removed which is a major "win"
from a user's perspective because it means that for both release and
for snapshot builds, both options will be available to users of the
binary hosted packages.
2. Since V3 and V4 require different init processes, we should simplify
daemon management by providing a single init script unique to each
variant.
3. Added CPE_ID and PKG_LICENSE and also added myself as the Makefile
MAINTAINER.
Discussion about the v4 initd script:
It should be noted that mimicking the systemd implementation in an init.d
script with procd was not straight forward. There are some quirks
associated with the interplay of the five executables (listed below)
with procd, but despite of them, the init script works reliably based
on my somewhat extensive testing.
My observations and justification for the script as-is:
1a. procd_set_param command /usr/sbin/nfsdcld cannot be started with an
appended -F as doing so will somehow cause the executable to never
connect to the communication pipe: /var/lib/nfs/rpc_pipefs/nfsd/cld.
In fact, if you run `watch -n 1 tree /var/lib/nfs/rpc_pipefs` while
calling the init.d script to start, this pipe will quickly disappear
resulting in nfsdcld being unable to find it and thus fail to track
clients. On the other hand, starting it as I have in the init.d
script works as expected.
1b. Starting /usr/sbin/nfsdcld even with the -F arg outside of procd
also results in the communication pipe quickly disappearing.
2. Even though rpc.nfsd is a user space util, and even though it runs
and then exits, it must be started by procd with the procd_set_param
or else, the communication pipe: /var/lib/nfs/rpc_pipefs/nfsd/cld
will again quickly disappear breaking client tracking.
3. The addition of the umountem function keeps syslog output cleaner as
a shutdown of rpc.idmapd will cause the following to be logged:
daemon.warn rpc.idmapd[xxxxx]: dirscancb: scandir(/var/lib/nfs/rpc_pipefs//nfs): No such file or directory
Adding a 1 sec delay allows procd to kill it before we umount the
nfs related mounts to prevent that warning.
4. I can find no way to suppress rpc.idmapd and nfsv4.exportd reporting
that they received a SIGTERM (signal 15). The syslog will contain
two lines on exit, e.g.:
daemon.warn rpc.idmapd[1894]: exiting on signal 15
daemon.notice nfsv4.exportd[1893]: Caught signal 15, exiting.
The result of points 1 and 2 mean that if a users queries the status of
the daemon when running, (ie /etc/init.d/nfsv4d status), it will show:
running (2/4) despite the kernel serving up NFSV4 mounts 100% correctly.
I am unaware of a more perfect approximation of the systemd units.
List of the five needed calls:
* /usr/sbin/nfsv4.exportd (run once then quit)
* /usr/sbin/rpc.idmapd (needs to continue running)
* /usr/sbin/nfsdcld (needs to continue running)
* /usr/sbin/exportfs -r (run once then quit)
* /usr/sbin/rpc.nfsd -N 3 (run once then quit)
1. As assessed by comparing the uncompressed img files from a build of a
minimal image for x86/64 with the v3 variant vs with the v4.
Both variants have been tested and work.
v3:
On a network node, the NFSV3 export is fully functional:
% mount -t nfs -o vers=3 10.9.8.1:/mnt/data/nfs/misc ok
% mount | grep ok
10.9.8.1:/mnt/data/nfs/misc on /home/facade/ok type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.9.8.1,mountvers=3,mountport=32780,mountproto=udp,local_lock=none,addr=10.9.8.1)
v4:
On a network node, the NFSV4 export is fully functional:
% mount 10.9.8.1:/misc ok
% mount | grep ok
10.9.8.1:/mnt/data/nfs/misc on /home/facade/ok type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.9.8.102,local_lock=none,addr=10.9.8.1)
Finally, added 240-fix-cleanup_lockfiles-function-linkage-in-exportd.patch[1]
1. https://marc.info/?l=linux-nfs&m=175604879721922&w=2
From commit msg therein:
The cleanup_lockfiles function in utils/exportd/exportd.c was declared
as 'inline void' without a proper function prototype, causing linker
errors during the build process:
exportd.c:(.text+0x5a): undefined reference to `cleanup_lockfiles'
exportd.c:(.text.startup+0x317): undefined reference to `cleanup_lockfiles'
This occurred because:
1. The inline keyword prevented the compiler from generating a callable
function symbol in some build configurations
2. The function lacked a proper prototype declaration, triggering
-Werror=missing-prototypes
The fix changes the function to:
- Remove the 'inline' keyword to ensure symbol generation
- Add a proper static function prototype
- Make the function 'static' since it's only used within exportd.c
This resolves both the linking error and the missing prototype warning,
allowing exportd to build successfully in OpenWrt's cross-compilation
environment.

Subject: [PATCH] fix cleanup_lockfiles function linkage in exportd
|
||||
|
||||
The cleanup_lockfiles function in utils/exportd/exportd.c was declared
|
||||
as 'inline void' without a proper function prototype, causing linker
|
||||
errors during the build process:
|
||||
|
||||
exportd.c:(.text+0x5a): undefined reference to `cleanup_lockfiles'
|
||||
exportd.c:(.text.startup+0x317): undefined reference to `cleanup_lockfiles'
|
||||
|
||||
This occurred because:
|
||||
1. The inline keyword prevented the compiler from generating a callable
|
||||
function symbol in some build configurations
|
||||
2. The function lacked a proper prototype declaration, triggering
|
||||
-Werror=missing-prototypes
|
||||
|
||||
The fix changes the function to:
|
||||
- Remove the 'inline' keyword to ensure symbol generation
|
||||
- Add a proper static function prototype
|
||||
- Make the function 'static' since it's only used within exportd.c
|
||||
|
||||
This resolves both the linking error and the missing prototype warning,
|
||||
allowing exportd to build successfully in OpenWrt's cross-compilation
|
||||
environment.
