+# DESCRIPTION
|
|
|
777f42 |
+#
|
|
|
777f42 |
+# This macro checks if the compiler supports one of GCC's function
|
|
|
777f42 |
+# attributes; many other compilers also provide function attributes with
|
|
|
777f42 |
+# the same syntax. Compiler warnings are used to detect supported
|
|
|
777f42 |
+# attributes as unsupported ones are ignored by default so quieting
|
|
|
777f42 |
+# warnings when using this macro will yield false positives.
|
|
|
777f42 |
+#
|
|
|
777f42 |
+# The ATTRIBUTE parameter holds the name of the attribute to be checked.
|
|
|
777f42 |
+#
|
|
|
777f42 |
+# If ATTRIBUTE is supported define HAVE_FUNC_ATTRIBUTE_<ATTRIBUTE>.
|
|
|
777f42 |
+#
|
|
|
777f42 |
+# The macro caches its result in the ax_cv_have_func_attribute_<attribute>
|
|
|
777f42 |
+# variable.
|
|
|
777f42 |

|
|
|
777f42 |
+nfsdcld is the NFSv4 client tracking daemon. It is not necessary to run
|
|
|
777f42 |
+this daemon on machines that are not acting as NFSv4 servers.
|
|
|
777f42 |
+.PP
|
|
|
777f42 |
+When a network partition is combined with a server reboot, there are
|
|
|
777f42 |
+edge conditions that can cause the server to grant lock reclaims when
|
|
|
777f42 |
+other clients have taken conflicting locks in the interim. A more detailed
|
|
|
777f42 |
+explanation of this issue is described in \s-1RFC\s0 3530, section 8.6.3.
|
|
|
777f42 |
+.PP
|
|
|
777f42 |
+In order to prevent these problems, the server must track a small amount
|
|
|
777f42 |
+of per-client information on stable storage. This daemon provides the
|
|
|
777f42 |
+userspace piece of that functionality.

|
777f42 |
+The Linux kernel NFSv4 server has historically tracked this information
|
|
|
777f42 |
+on stable storage by manipulating information on the filesystem
|
|
|
777f42 |
+directly, in the directory to which \fI/proc/fs/nfsd/nfsv4recoverydir\fR
|
|
|
777f42 |
+points.
|
|
|
777f42 |
+.PP
|
|
|
777f42 |
+This changed with the original introduction of \fBnfsdcld\fR upcall in kernel version 3.4,
|
|
|
777f42 |
+which was later deprecated in favor of the \fBnfsdcltrack\fR(8) usermodehelper
|
|
|
777f42 |
+program, support for which was added in kernel version 3.8. However, since the
|
|
|
777f42 |
+usermodehelper upcall does not work in containers, support for a new version of
|
|
|
777f42 |
+the \fBnfsdcld\fR upcall was added in kernel version 5.2.
|
|
|
777f42 |
+.PP
|
|
|
777f42 |
+This daemon requires a kernel that supports the \fBnfsdcld\fR upcall. On older kernels, if
|
|
|
777f42 |
+the legacy client name tracking code was in use, then the kernel would not create the
|
|
|
777f42 |
+pipe that \fBnfsdcld\fR uses to talk to the kernel. On newer kernels, nfsd attempts to
|
|
|
777f42 |
+initialize client tracking in the following order: First, the \fBnfsdcld\fR upcall. Second,
|
|
|
777f42 |
+the \fBnfsdcltrack\fR usermodehelper upcall. Finally, the legacy client tracking.
|
|
|
777f42 |
+.PP
|
|
|
777f42 |
+This daemon should be run as root, as the pipe that it uses to communicate
|
|
|
777f42 |
+with the kernel is only accessable by root. The daemon however does drop all
|
|
|
777f42 |
+superuser capabilities after starting. Because of this, the \fIstoragedir\fR
|
|
|
777f42 |
+should be owned by root, and be readable and writable by owner.
|
|
|
777f42 |
+.PP
|
|
|
777f42 |
+The daemon now supports different upcall versions to allow the kernel to pass additional
|
|
|
777f42 |
+data to be stored in the on-disk database. The kernel will query the supported upcall
|
|
|
777f42 |
+version from \fBnfsdcld\fR during client tracking initialization. A restart of \fBnfsd\fR is
|
|
|
777f42 |
+not necessary after upgrading \fBnfsdcld\fR, however \fBnfsd\fR will not use a later upcall
|
|
|
777f42 |
+version until restart. A restart of \fBnfsd is necessary\fR after downgrading \fBnfsdcld\fR,
|
|
|
777f42 |
+to ensure that \fBnfsd\fR does not use an upcall version that \fBnfsdcld\fR does not support.
|
|
|
777f42 |
+Additionally, a downgrade of \fBnfsdcld\fR requires the schema of the on-disk database to
|
|
|
777f42 |
+be downgraded as well. That can be accomplished using the \fBclddb-tool\fR(8) utility.

+ * Explanation:
|
|
|
777f42 |

|
|
|
777f42 |
+ * This file contains the code to manage the sqlite backend database for the
|
|
|
777f42 |
+ * nfsdcld client tracking daemon.
|
|
|
777f42 |
+ *
|
|
|
777f42 |
+ * The main database is called main.sqlite and contains the following tables:
|
|
|
777f42 |
+ *
|
|
|
777f42 |
+ * parameters: simple key/value pairs for storing database info
|
|
|
777f42 |
+ *
|
|
|
777f42 |
+ * grace: a "current" column containing an INTEGER representing the current
|
|
|
777f42 |
+ * epoch (where should new values be stored) and a "recovery" column
|
|
|
777f42 |
+ * containing an INTEGER representing the recovery epoch (from what
|
|
|
777f42 |
+ * epoch are we allowed to recover). A recovery epoch of 0 means
|
|
|
777f42 |
+ * normal operation (grace period not in force). Note: sqlite stores
|
|
|
777f42 |
+ * integers as signed values, so these must be cast to a uint64_t when
|
|
|
777f42 |
+ * retrieving them from the database and back to an int64_t when storing
|
|
|
777f42 |
+ * them in the database.
|
|
|
777f42 |
+ *
|
|
|
777f42 |
+ * rec-CCCCCCCCCCCCCCCC (where C is the hex representation of the epoch value):
|
|
|
777f42 |
+ * an "id" column containing a BLOB with the long-form clientid
|
|
|
777f42 |
+ * as sent by the client, and a "princhash" column containing a BLOB
|
|
|
777f42 |
+ * with the sha256 hash of the kerberos principal (if available).
