35 1/ utils/mountd/rmtab.c::mountlist_list
37 This routine stats the rmtab file to see if it has changed. It
38 if has, it cleans up it's old copy of the data. But it still
39 always re-read the file, thus returning multiple copies of the
40 data on consecutive calls without intervening changes.
41 "Showmount -a" didn't show this as it appears to sort/unique the
42 data, but 'strace showmount -a' showed that the size of the
43 datagram that it received grew.
45 I moved the getrmtabent loop inside the mtime test.
47 2/ utils/exportfs/exportfs.c
49 Many routines used the m_path field of m_export instead of
51 According to the comment in nfslib.h, m_path should only
52 be used when processing a mount request (i.e. in mountd)
53 where the mountpoint may be a subdirectory of the export point.
55 I changed all occurances of m_path to e_path
58 3/ utils/exportfs/exportfs.c:main
60 extra arguments are not meaningful with -a or -r, but
61 exportfs accepted them and then ignored the -a/-r, expect that
62 -r would still unexport everything first.
64 I generate an error if there are extra args and f_all
66 4/ utils/exportfs/exportfs.c:main
67 extract dump out as a special case.
69 5/ utils/exportfs/exportfs.c
70 made f_reexport a local variable.
73 6/ utils/exportfs/exportfs.c:main,exportall
75 support/export/rmtab.c
76 only mayexport on newly created entries, don't set xtabent at all
78 7/ support/include/nfslib.h
80 add #define _PATH_PROC_EXPORTS to be /proc/fs/nds/exports
82 8/ support/export/xtab.c
84 xtab_mount_read loads data from _PATH_PROC_EXPORTS if it exists,
88 9/ support/export/xtab.c
90 xtab_mount_read now sets m_exported, and NOT
93 removed the append arguement from xtab_write as it was
96 added is_export flag to xtab_write similar to xtab_read
97 if is_export, only write entries with m_xtabent or m_addxtab
98 if !is_export, only write entries with m_exported
100 10/ support/export/export.c::export_allowed_internal
102 added test for exp->m_mayexport, as the export tree
103 may have entries that are no longer allowed to be exported,
104 and so shouldn't caused deduced exported by rmtab_read
106 11/ utils/exportfs/exportfs.c::main
107 error checking of flags.
109 12/ utils/exportfs/exportfs.c
111 total rewrite of export and unexport logic.
113 - build an exportslist of valid exports, based on
114 current etab file and arguments,
115 - read rmtab to instantiate relevant wild card entries
116 - read etab to find out what is currently exported
117 - synchronise intention with reality
118 - write out etab and xtab
121 discard the m_addxtab flag
122 add m_changed flag so we know what to report in exportfs
124 14/ utils/mountd/auth.c:auth_authenticate
126 the value returned by gethostbyaddr was trusted.
128 It now follows this with a call to gethostbyname
129 and checks that the address is in the list.
131 15/ support/export/nfsctl.c::cltsetup,expsetup
133 force client names to lowercase as kernel is
136 16/ quietened a few compiler warnings
138 17/ support/export/client:client_lookup
140 look for pre-existing client with same name before creating
143 18/ support/include/exportfs.h
145 The ordering of the MCL_* enum was:
146 ANONYMOUS, FQDN, SUBNETWORK, WILDCARD, NETGROUP
148 I moved ANONYMOUS to the end.
150 The ordering is significant when an export entry is being searched for to
151 match a given address. There are two problems with ANONYMOUS being first.
153 1/ if a directory is exported rw to a couple of hosts and ro to everyone else,
154 then the ro case will always be found first and the privileged hosts won't get
156 2/ When mountd gets a request to mount an ANONYMOUSly exported tree, it creates a FQDN
157 export entry for the specific host, and writes it to xtab.
158 When another request comes from the same host, the ANONYMOUS entry is found again,
159 before the new FQDN entry, so it creates another FQDN entry and writes it to xtab
160 again. If causes bloat in xtab.
162 Putting ANONYMOUS at the end reflects it's nature as a catch-all
164 19/ utils/exportfs/exportfs.man
165 many updates to the man page to reflect changes to the code
167 -----------------------
173 - allow exportfs to modify rmtab file
174 - make sure kernel never gets two clients with same IP address
175 - possible kernel should reject
176 - needs to be some way to lookup client in kernel by IP address
177 - maybe get kernel to do case-insensitive comparisons on client names
178 - remove unused clients from kernel
180 - change etab to xtab and xtab to xtab.active
182 - timestamp and/or statd-stamp in rmtab for removing old entries.
