9 thing if a pathname from rmtab was a subdirectory of an export-point

66 1/ utils/mountd/rmtab.c::mountlist_list
68 This routine stats the rmtab file to see if it has changed. It
69 if has, it cleans up it's old copy of the data. But it still
70 always re-read the file, thus returning multiple copies of the
71 data on consecutive calls without intervening changes.
72 "Showmount -a" didn't show this as it appears to sort/unique the
73 data, but 'strace showmount -a' showed that the size of the
74 datagram that it received grew.
76 I moved the getrmtabent loop inside the mtime test.
78 2/ utils/exportfs/exportfs.c
80 Many routines used the m_path field of m_export instead of
82 According to the comment in nfslib.h, m_path should only
83 be used when processing a mount request (i.e. in mountd)
84 where the mountpoint may be a subdirectory of the export point.
86 I changed all occurances of m_path to e_path
89 3/ utils/exportfs/exportfs.c:main
91 extra arguments are not meaningful with -a or -r, but
92 exportfs accepted them and then ignored the -a/-r, expect that
93 -r would still unexport everything first.
95 I generate an error if there are extra args and f_all
97 4/ utils/exportfs/exportfs.c:main
98 extract dump out as a special case.
100 5/ utils/exportfs/exportfs.c
101 made f_reexport a local variable.
104 6/ utils/exportfs/exportfs.c:main,exportall
106 support/export/rmtab.c
107 only mayexport on newly created entries, don't set xtabent at all
109 7/ support/include/nfslib.h
111 add #define _PATH_PROC_EXPORTS to be /proc/fs/nds/exports
113 8/ support/export/xtab.c
115 xtab_mount_read loads data from _PATH_PROC_EXPORTS if it exists,
119 9/ support/export/xtab.c
121 xtab_mount_read now sets m_exported, and NOT
122 xtabent and mayexport
124 removed the append arguement from xtab_write as it was
127 added is_export flag to xtab_write similar to xtab_read
128 if is_export, only write entries with m_xtabent or m_addxtab
129 if !is_export, only write entries with m_exported
131 10/ support/export/export.c::export_allowed_internal
133 added test for exp->m_mayexport, as the export tree
134 may have entries that are no longer allowed to be exported,
135 and so shouldn't caused deduced exported by rmtab_read
137 11/ utils/exportfs/exportfs.c::main
138 error checking of flags.
140 12/ utils/exportfs/exportfs.c
142 total rewrite of export and unexport logic.
144 - build an exportslist of valid exports, based on
145 current etab file and arguments,
146 - read rmtab to instantiate relevant wild card entries
147 - read etab to find out what is currently exported
148 - synchronise intention with reality
149 - write out etab and xtab
152 discard the m_addxtab flag
153 add m_changed flag so we know what to report in exportfs
155 14/ utils/mountd/auth.c:auth_authenticate
157 the value returned by gethostbyaddr was trusted.
159 It now follows this with a call to gethostbyname
160 and checks that the address is in the list.
162 15/ support/export/nfsctl.c::cltsetup,expsetup
164 force client names to lowercase as kernel is
167 16/ quietened a few compiler warnings
169 17/ support/export/client:client_lookup
171 look for pre-existing client with same name before creating
174 18/ support/include/exportfs.h
176 The ordering of the MCL_* enum was:
177 ANONYMOUS, FQDN, SUBNETWORK, WILDCARD, NETGROUP
179 I moved ANONYMOUS to the end.
181 The ordering is significant when an export entry is being searched for to
182 match a given address. There are two problems with ANONYMOUS being first.
184 1/ if a directory is exported rw to a couple of hosts and ro to everyone else,
185 then the ro case will always be found first and the privileged hosts won't get
187 2/ When mountd gets a request to mount an ANONYMOUSly exported tree, it creates a FQDN
188 export entry for the specific host, and writes it to xtab.
189 When another request comes from the same host, the ANONYMOUS entry is found again,
190 before the new FQDN entry, so it creates another FQDN entry and writes it to xtab
191 again. If causes bloat in xtab.
193 Putting ANONYMOUS at the end reflects it's nature as a catch-all
195 19/ utils/exportfs/exportfs.man
196 many updates to the man page to reflect changes to the code
198 -----------------------
204 - allow exportfs to modify rmtab file
205 - make sure kernel never gets two clients with same IP address
206 - possible kernel should reject
207 - needs to be some way to lookup client in kernel by IP address
208 - maybe get kernel to do case-insensitive comparisons on client names
209 - remove unused clients from kernel
211 - change etab to xtab and xtab to xtab.active
213 - timestamp and/or statd-stamp in rmtab for removing old entries.
