commit cfe41d6f06af0e7744c1ca30503f93d28aca4d8b
Author: NeilBrown <neilb@suse.de>

gssd: fix crash in debug message.
A recent cleanup of debug messages added func and tid format specifiers
to a debug message (when full hostname was different), but the func name
and tid were NOT added as arguments.
Consequently there weren't enough args, random bytes of the stack were
interpreted as a pointer, and rpc.gssd crashed (when -v was specified).

mount.nfs Fix error reporting for already mounted shares
When mount is triggered for an already mounted
share (using auto negotiation), it displays
"mount.nfs: Protocol not supported" or
"mount.nfs: access denied by server while mounting"
instead of EBUSY. This easily causes confusion if
the mount was not tried verbose :

commit 4dd8d833c9350d42528ada0fd65aee41b712f41d
Author: Steve Dickson <steved@redhat.com>
Date: Tue Jul 20 17:14:04 2021 -0400
mount.nfs: Fix the sloppy option processing
The new mount API broke how the sloppy option is parsed.
So the option processing needs to be moved up in
the mount.nfs command.
The option needs to be the first option in the string
that is passed into the kernel with the -s mount(8)
and/or the -o sloppy is used.
Commit 92b664ef fixed the process of the -s flag
and this version fixes the -o sloppy processing
as well works when libmount-mount is and is not
enabled plus cleans up the mount options passed
to the kernel.

+.SH NAME
+
+nfsrahead \- Configure the readahead for NFS mounts
+
+.SH SYNOPSIS
+
+nfsrahead [-F] [-d] <device>
+
+.SH DESCRIPTION
+
+\fInfsrahead\fR is a tool intended to be used with udev to set the \fIread_ahead_kb\fR parameter of NFS mounts, according to the configuration file (see \fICONFIGURATION\fR). \fIdevice\fR is the device number for the NFS backing device as provided by the kernel.
+
+.SH OPTIONS
+.TP
+.B -F
+Send messages to
+.I stderr
+instead of
+.I syslog
+
+.TP
+.B -d
+Increase the debugging level.
+
+.SH CONFIGURATION
+.I nfsrahead
+is configured in
+.IR /etc/nfs.conf ,
+in the section titled
+.IR nfsrahead .
+It accepts the following configurations.
+
+.TP
+.B nfs=<value>
+The readahead value applied to NFSv3 mounts.
+
+.TP
+.B nfs4=<value>
+The readahead value applied to NFSv4 mounts.
+
+.TP
+.B default=<value>
+The default configuration when none of the configurations above is set.
+
+.SH EXAMPLE CONFIGURATION
+[nfsrahead]
+.br
+nfs=15000 # readahead of 15000 for NFSv3 mounts
+.br
+nfs4=16000 # readahead of 16000 for NFSv4 mounts
+.br
+default=128 # default is 128

+.P
+.SS rpcctl xprt \fR- \fBCommands operating on individual transports
+.IP "\fBremove \fIXPRT"
+Removes the specified \fIXPRT \fRfrom the system.
+Note that "main" transports cannot be removed.
+.P
+.IP "\fBset \fIXPRT \fBdstaddr \fINEWADDR"
+Change the destination address of the specified \fIXPRT \fR to \fINEWADDR\fR.
+\fINEWADDR \fRcan be an IP address, DNS name, or anything else resolvable by \fBgethostbyname\fR(3).

idmapd: Fix error status when nfs-idmapd exits
nfs-idmapd.service would report following error when stopped:
Starting NFSv4 ID-name mapping service...
rpc.idmapd[1198]: Setting log level to 0
Started NFSv4 ID-name mapping service.
rpc.idmapd[1198]: exiting on signal 15
Stopping NFSv4 ID-name mapping service...
nfs-idmapd.service: Main process exited, code=exited, status=1/FAILURE
nfs-idmapd.service: Failed with result 'exit-code'.
Stopped NFSv4 ID-name mapping service.
commit 93e8f092(idmapd: Add graceful exit and resource cleanup)
redirected SIGTERM, so when executing "systemctl stop nfs-idmapd", the
main() of idmapd would running to tail to return, while it returned 1
which considered as error by systemd.
So here just return 0 in main().

rpc-statd.service: Stop rpcbind and rpc.stat in an exit race
When `systemctl stop rpcbind.socket` is run, the dependency means
that systemd first sends SIGTERM to rpcbind, then sigterm to rpc.statd.
On SIGTERM, rpcbind tears down /var/run/rpcbind.sock. However,
rpc-statd on SIGTERM attempts to unregister from rpcbind
systemd needs to wait for rpc.statd to exit before sending
SIGTERM to rpcbind
