TF
71TF/03 Make the exiwhat support code safe for signals. Previously Exim might
72 lock up or crash if it happened to be inside a call to libc when it
73 got a SIGUSR1 from exiwhat.
74
75 The SIGUSR1 handler appends the current process status to the process
76 log which is later printed by exiwhat. It used to use the general
77 purpose logging code to do this, but several functions it calls are
78 not safe for signals.
79
80 The new output code in the SIGUSR1 handler is specific to the process
81 log, and simple enough that it's easy to inspect for signal safety.
82 Removing some special cases also simplifies the general logging code.
83 Removing the spurious timestamps from the process log simplifies
84 exiwhat.
85
c99ce5c9
TF
86TF/04 Improved ratelimit ACL condition.
87
88 The /noupdate option has been deprecated in favour of /readonly which
89 has clearer semantics. The /leaky, /strict, and /readonly update modes
90 are mutually exclusive. The update mode is no longer included in the
91 database key; it just determines when the database is updated. (This
92 means that when you upgrde Exim will forget old rate measurements.)
93
94 Exim now checks that the per_* options are used with an update mode that
95 makes sense for the current ACL. For example, when Exim is processing a
96 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
97 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
98 must specify per_mail/readonly. If you omit the update mode it defaults to
99 /leaky where that makes sense (as before) or /readonly where required.
100
101 The /noupdate option is now undocumented but still supported for
102 backwards compatibility. It is equivalent to /readonly except that in
103 ACLs where /readonly is required you may specify /leaky/noupdate or
104 /strict/noupdate which are treated the same as /readonly.
105
106 A useful new feature is the /count= option. This is a generalization
107 of the per_byte option, so that you can measure the throughput of other
108 aggregate values. For example, the per_byte option is now equivalent
109 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
110
111 The per_rcpt option has been generalized using the /count= mechanism
112 (though it's more complicated than the per_byte equivalence). When it is
113 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
114 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
115 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
116 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
117 Note that using per_rcpt with a non-readonly update mode in more than
118 one ACL will cause the recipients to be double-counted. (The per_mail
119 and per_byte options don't have this problem.)
120
121 The handling of very low rates has changed slightly. If the computed rate
122 is less than the event's count (usually one) then this event is the first
123 after a long gap. In this case the rate is set to the same as this event's
124 count, so that the first message of a spam run is counted properly.
125
126 The major new feature is a mechanism for counting the rate of unique
127 events. The new per_addr option counts the number of different
128 recipients that someone has sent messages to in the last time period. It
129 behaves like per_rcpt if all the recipient addresses are different, but
130 duplicate recipient addresses do not increase the measured rate. Like
131 the /count= option this is a general mechanism, so the per_addr option
132 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
133 example, measure the rate that a client uses different sender addresses
134 with the options per_mail/unique=$sender_address. There are further
135 details in the main documentation.

708
6a3bceb1
PH
709PH/02 When an IPv6 address is converted to a string for single-key lookup
710 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
711 dots are used instead of colons so that keys in lsearch files need not
712 contain colons. This was done some time before quoting was made available
713 in lsearch files. However, iplsearch files do require colons in IPv6 keys
714 (notated using the quote facility) so as to distinguish them from IPv4
715 keys. This meant that lookups for IP addresses in host lists did not work
716 for iplsearch lookups.
717
718 This has been fixed by arranging for IPv6 addresses to be expressed with
719 colons if the lookup type is iplsearch. This is not incompatible, because
720 previously such lookups could never work.
721
722 The situation is now rather anomolous, since one *can* have colons in
723 ordinary lsearch keys. However, making the change in all cases is
724 incompatible and would probably break a number of configurations.

729MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
730 conversion specification without a maximum field width, thereby enabling
731 a rogue spamd server to cause a buffer overflow. While nobody in their
732 right mind would setup Exim to query an untrusted spamd server, an
733 attacker that gains access to a server running spamd could potentially
734 exploit this vulnerability to run arbitrary code as the Exim user.

MH
739MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
740 a directory entry by the name of the lookup key. Previously, if a
741 symlink pointed to a non-existing file or a file in a directory that
742 Exim lacked permissions to read, a lookup for a key matching that
743 symlink would fail. Now it is enough that a matching directory entry
744 exists, symlink or not. (Bugzilla 503.)

810MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
811 is unset (happens when testing with -bh and -oMi isn't used). Thanks to
812 Jan Srzednicki.
813

PH
814PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
815 issue a MAIL command.

431b7361
PH
817PH/02 In an ACL statement such as
818
819 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
820
821 if a client was not listed at all, or was listed with a value other than
822 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
823 the condition was not true (as it should be), so access was not denied.
824 The bug was that the ! inversion was incorrectly passed on to the second
825 item. This has been fixed.
826
827PH/03 Added additional dnslists conditions == and =& which are different from
828 = and & when the dns lookup returns more than one IP address.
829
83da1223
PH
830PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
831 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
832
54fc8428
PH
833PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
834 FSYNC, which compiles an option called disable_fsync that allows for
835 bypassing fsync(). The documentation is heavily laced with warnings.

PH
839PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
840 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
841 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
842 including adding "make clean"; (3) Added -fPIC when compiling the test
843 dynamically loaded module, to get rid of a warning.

0e8a9471
MH
845MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
846 message fails, move_frozen_messages = true and ignore_bounce_errors_after
847 = 0s. The bug is otherwise harmless.
848
f0872424
PH
849PH/07 There was a bug in the dovecot authenticator such that the value of
850 $auth1 could be overwritten, and so not correctly preserved, after a
851 successful authentication. This usually meant that the value preserved by
852 the server_setid option was incorrect.

PH
858PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
859 run for batched SMTP input. It is now run at the start of every message
860 in the batch. While fixing this I discovered that the process information
861 (output by running exiwhat) was not always getting set for -bs and -bS
862 input. This is fixed, and it now also says "batched" for BSMTP.

867 patch, slightly modified), and move the expansion of helo_data till after
868 the connection is made in the smtp transport (so it can use these
869 values).

PH
913PH/27 When a message times out after an over-quota error from an Exim-imposed
914 quota, the bounce message says "mailbox is full". This message was not

916 be the same.
917
0e20aff9
MH
918MH/03 Made $recipients available in local_scan(). local_scan() already has
919 better access to the recipient list through recipients_list[], but
920 $recipients can be useful in postmaster-provided expansion strings.
921
ca86f471
PH
922PH/28 The $smtp_command and $smtp_command_argument variables were not correct
923 in the case of a MAIL command with additional options following the
924 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
925 were accidentally chopped off.
926
a14e5636
PH
927PH/29 SMTP synchronization checks are implemented when a command is read -
928 there is a check that no more input is waiting when there shouldn't be
929 any. However, for some commands, a delay in an ACL can mean that it is
930 some time before the response is written. In this time, more input might
931 arrive, invalidly. So now there are extra checks after an ACL has run for
932 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
933 pipelining has not been advertised.
934
ec95d1a6
PH
935PH/30 MH's patch to allow iscntrl() characters to be list separators.

PH
941PH/32 Change the Dovecot authenticator to use read() and write() on the socket
942 instead of the C I/O that was originally supplied, because problems were
943 reported on Solaris.
944
58c01c94
PH
945PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
946 Exim which did not show up earlier: it was assuming that a call to
947 SSL_CTX_set_info_callback() might give an error value. In fact, there is
948 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
949 was a macro that became an assignment, so it seemed to work. This has
950 changed to a proper function call with a void return, hence the compile
951 error. Exim's code has been fixed.

3ce62588
PH
962 "Completed" line in the log. When some messages of this type were
963 selected by exigrep, they were listed as "not completed". Others were
964 picked up by some special patterns. I have improved the selection
965 criteria to be more general.

c456d9bb
PH
967PH/38 The host_find_failed option in the manualroute router can now be set
968 to "ignore", to completely ignore a host whose IP address cannot be
969 found. If all hosts are ignored, the behaviour is controlled by the new
970 host_all_ignored option.
971
cd9868ec
PH
972PH/39 In a list of hosts for manualroute, if one item (either because of multi-
973 homing or because of multiple MX records with /mx) generated more than
974 one IP address, and the following item turned out to be the local host,
975 all the secondary addresses of the first item were incorrectly removed
976 from the list, along with the local host and any following hosts (which
977 is what is supposed to happen).
978
ebeaf996
PH
979PH/40 When Exim receives a message, it writes the login name, uid, and gid of
980 whoever called Exim into the -H file. In the case of the daemon it was
981 behaving confusingly. When first started, it used values for whoever
982 started the daemon, but after a SIGHUP it used the Exim user (because it
983 calls itself on a restart). I have changed the code so that it now always
984 uses the Exim user.
985
2679d413
PH
986PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
987 message are rejected with the same error (e.g. no authentication or bad
988 sender address), and a DATA command is nevertheless sent (as can happen
989 with PIPELINING or a stupid MUA), the error message that was given to the
990 RCPT commands is included in the rejection of the DATA command. This is
991 intended to be helpful for MUAs that show only the final error to their
992 users.

1005
58eb016e 1006PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1007 the response to the final '.' that terminates a message, but only in the
1008 case where the client has not sent further data following the '.'
1009 (unfortunately, this is allowed). However, in many cases there won't be
1010 any further data because there won't be any more messages to send. A call
1011 to select() can be used: if it shows that the input is "ready", there is
1012 either input waiting, or the socket has been closed. An attempt to read
1013 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1014 would have sent an OK response which the client would never have see.
563b63fa
PH
1015 This could lead to message repetition. This fix should cure that, at
1016 least in a lot of common cases.

1022Exim version 4.66
1023-----------------
1024
1025PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1026 fixed by 4.65/MH/01 (is this a record?) are fixed:
1027
1028 (i) An empty string was always treated as zero by the numeric comparison
1029 operators. This behaviour has been restored.
1030
1031 (ii) It is documented that the numeric comparison operators always treat
1032 their arguments as decimal numbers. This was broken in that numbers
1033 starting with 0 were being interpreted as octal.
1034
1035 While fixing these problems I realized that there was another issue that
1036 hadn't been noticed. Values of message_size_limit (both the global option
1037 and the transport option) were treated as octal if they started with 0.
1038 The documentation was vague. These values are now always treated as
1039 decimal, and I will make that clear in the documentation.

MH
1049MH/01 Don't check that the operands of numeric comparison operators are

4362ff0d
PH
1053PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1054 child addresses, Exim now panics and dies. Previously, because the count
1055 is held in a short int, deliveries were likely to be lost. As such a
1056 large number of recipients for a single message is ridiculous
1057 (performance will be very, very poor), I have chosen to impose a limit
1058 rather than extend the field.

TK
1064TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1065 leftover -K file (the existence of which was triggered by #402).
1066 While we were at it, introduced process PID as part of the -K
1067 filename. This should rule out race conditions when creating
1068 these files.
1069
1070TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1071 processing considerably. Previous code took too long for large mails,
1072 triggering a timeout which in turn triggers #401.
1073
1074TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1075 in the DK code in transports.c. sendfile() is not really portable,
1076 hence the _LINUX specificness.

1077
1078TF/01 In the add_headers option to the mail command in an Exim filter,

1080 header after the first one which had an odd number of characters
1081 in the field name.
1082
2b1c6e3a
PH
1083PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1084 callout verification, Exim cached a "reject" for the entire domain. This
1085 is correct for most verifications, but it is not correct for a recipient
1086 verification with use_sender or use_postmaster set, because in that case
1087 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1088 case of MAIL FROM:<> rejection from other early rejections (e.g.
1089 rejection of HELO). When verifying a recipient using a non-null MAIL
1090 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1091 Whatever the result of the callout, the value of the domain cache is
1092 left unchanged (for any other kind of callout, getting as far as trying
1093 RCPT means that the domain itself is ok).

1098PH/03 On Solaris, an unexpectedly close socket (dropped connection) can

PH
1127PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1128 hostname. This is wrong, because it relates to the incoming message (and
1129 probably the interface on which it is arriving) and not to the outgoing
1130 callout (which could be using a different interface). This has been
1131 changed to use the value of the helo_data option from the smtp transport
1132 instead - this is what is used when a message is actually being sent. If
1133 there is no remote transport (possible with a router that sets up host
1134 addresses), $smtp_active_hostname is used.
6ea85e9a 1135
14aa5a05 1136PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1137 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1138 (a) The code assumed that strncpy() returns a negative number on buffer
1139 overflow, which isn't the case. Replaced with Exim's string_format()
1140 function.
1141 (b) There were several signed/unsigned issues. I just did the minimum
1142 hacking in of casts. There is scope for a larger refactoring.
1143 (c) The code used strcasecmp() which is not a standard C function.
1144 Replaced with Exim's strcmpic() function.
1145 (d) The code set only $1; it now sets $auth1 as well.
1146 (e) A simple test gave the error "authentication client didn't specify
1147 service in request". It would seem that Dovecot has changed its
1148 interface. Fortunately there's a specification; I followed it and
1149 changed what the client sends and it appears to be working now.

PH
1154PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1155 address A is aliased to B and C, where B exists and C does not. Without
1156 -v the output is "A verified" because verification stops after a
1157 successful redirection if more than one address is generated. However,
1158 with -v the child addresses are also verified. Exim was outputting "A
1159 failed to verify" and then showing the successful verification for C,
1160 with its parentage. It now outputs "B failed to verify", showing B's
1161 parentage before showing the successful verification of C.

PH
1163PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1164 look up a TXT record in a specific list after matching in a combined
1165 list.
1166
322050c2
PH
1167PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1168 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1169 they consult the DNS. I had assumed they would set it the way they
1170 wanted; and indeed my experiments on Linux seem to show that in some
1171 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1172 To be on the safe side, however, I have now made the interface to
1173 host_find_byname() similar to host_find_bydns(), with an argument
1174 containing the DNS resolver options. The host_find_byname() function now
1175 sets these options at its start, just as host_find_bydns() does. The smtp
1176 transport options dns_qualify_single and dns_search_parents are passed to
1177 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1178 of host_find_byname() use the default settings of RES_DEFNAMES
1179 (qualify_single) but not RES_DNSRCH (search_parents).
1180

PH
1181PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1182 spool_read_header() do less string testing, by means of a preliminary
1183 switch on the second character of optional "-foo" lines. (This is
1184 overdue, caused by the large number of possibilities that now exist.
1185 Originally there were few.) While I was there, I also converted the
1186 str(n)cmp tests so they don't re-test the leading "-" and the first
1187 character, in the hope this might squeeze out yet more improvement.
1188

PH
1189PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1190 flag allowing group syntax was set by the header_syntax check but not
1191 turned off, possible causing trouble later; (2) The flag was not being
1192 set at all for the header_verify test, causing "group"-style headers to
1193 be rejected. I have now set it in this case, and also caused header_
1194 verify to ignore an empty address taken from a group. While doing this, I
1195 came across some other cases where the code for allowing group syntax
1196 while scanning a header line wasn't quite right (mostly, not resetting
1197 the flag correctly in the right place). These bugs could have caused

1200PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1202 came from elsewhere) had *some* tests for NULL when it wrote to *reply,

PH
1206PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1207 feature that was used to support insecure browsers during the U.S. crypto
1208 embargo. It requires special client support, and Exim is probably the
1209 only MTA that supported it -- and would never use it because real RSA is
1210 always available. This code has been removed, because it had the bad
1211 effect of slowing Exim down by computing (never used) parameters for the
1212 RSA_EXPORT functionality.

1214PH/21 On the advice of Timo Sirainen, added a check to the dovecot

1217 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1218 if the connection is using TLS or if the remote IP is the same as the
1219 local IP, and the "valid-client-cert option" if a client certificate has
1220 been verified.

1251
1252PH/30 Exim was sometimes attempting to deliver messages that had suffered
1253 address errors (4xx response to RCPT) over the same connection as other
1254 messages routed to the same hosts. Such deliveries are always "forced",
1255 so retry times are not inspected. This resulted in far too many retries
1256 for the affected addresses. The effect occurred only when there were more
1257 hosts than the hosts_max_try setting in the smtp transport when it had
1258 the 4xx errors. Those hosts that it had tried were not added to the list
1259 of hosts for which the message was waiting, so if all were tried, there
1260 was no problem. Two fixes have been applied:
1261
1262 (i) If there are any address or message errors in an SMTP delivery, none
1263 of the hosts (tried or untried) are now added to the list of hosts
1264 for which the message is waiting, so the message should not be a
1265 candidate for sending over the same connection that was used for a
1266 successful delivery of some other message. This seems entirely
1267 reasonable: after all the message is NOT "waiting for some host".
1268 This is so "obvious" that I'm not sure why it wasn't done
1269 previously. Hope I haven't missed anything, but it can't do any
1270 harm, as the worst effect is to miss an optimization.
1271
1272 (ii) If, despite (i), such a delivery is accidentally attempted, the
1273 routing retry time is respected, so at least it doesn't keep
1274 hammering the server.

1289PH/35 The error "getsockname() failed: connection reset by peer" was being
1290 written to the panic log as well as the main log, but it isn't really
1291 panic-worthy as it just means the connection died rather early on. I have
1292 removed the panic log writing for the ECONNRESET error when getsockname()
1293 fails.
1294
48c7f9e2
PH
1295PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1296 runs only) independently of the message's sender address. This meant
1297 that, if the 4xx error was in fact related to the sender, a different
1298 message to the same recipient with a different sender could confuse
1299 things. In particualar, this can happen when sending to a greylisting
1300 server, but other circumstances could also provoke similar problems.
1301 I have changed the default so that the retry time for these errors is now
1302 based a combination of the sender and recipient addresses. This change
1303 can be overridden by setting address_retry_include_sender=false in the
1304 smtp transport.

1578 554 error is used if errno is still zero or contains ENOENT (which occurs

1602PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1603 folder from quota calculations, a direct delivery into this folder messed
1604 up the contents of the maildirsize file. This was because the regex was
1605 used only to exclude .Trash (or whatever) when the size of the mailbox
1606 was calculated. There was no check that a delivery was happening into an
1607 excluded directory. This bug has been fixed by ignoring all quota

1616PH/01 The code for finding all the local interface addresses on a FreeBSD
1617 system running IPv6 was broken. This may well have applied to all BSD
1618 systems, as well as to others that have similar system calls. The broken
1619 code found IPv4 interfaces correctly, but gave incorrect values for the
1620 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1621 that it would not match correctly against @[] and not recognize the IPv6
1622 addresses as local.

1700 additional section of a DNS packet that returns MX or SRV records.
1701 Instead, it always explicitly searches for A/AAAA records. This avoids
1702 major problems that occur when a DNS server includes only records of one
1703 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1704 fixed another bug: if SRV records were looked up and the corresponding
1705 address records were *not* found in the additional section, the port
1706 values from the SRV records were lost.

PH
1716PH/19 When calculating a retry time, Exim used to measure the "time since
1717 failure" by looking at the "first failed" field in the retry record. Now
1718 it does not use this if it is later than than the arrival time of the
1719 message. Instead it uses the arrival time. This makes for better
1720 behaviour in cases where some deliveries succeed, thus re-setting the
1721 "first failed" field. An example is a quota failure for a huge message
1722 when small messages continue to be delivered. Without this change, the
1723 "time since failure" will always be short, possible causing more frequent
1724 delivery attempts for the huge message than are intended.

PH
1821PH/42 The content-scanning code uses fopen() to create files in which to put
1822 message data. Previously it was not paying any attention to the mode of
1823 the files. Exim runs with umask(0) because the rest of the code creates
1824 files with open(), and sets the required mode explicitly. Thus, these
1825 files were ending up world-writeable. This was not a big issue, because,
1826 being within the spool directory, they were not world-accessible. I have
1827 created a function called modefopen, which takes an additional mode
1828 argument. It sets umask(777), creates the file, chmods it to the required
1829 mode, then resets the umask. All the relevant calls to fopen() in the
1830 content scanning code have been changed to use this function.

1842 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

1867
1868 (i) Exim was not creating retry information for temporary errors given
1869 for individual recipients after the DATA command when the smtp transport
1870 was used in LMTP mode. This meant that they could be retried too
1871 frequently, and not timed out correctly.
1872
1873 (ii) Exim was setting the flag that allows error details to be returned
1874 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1875 recipients that were returned after the DATA command.
1876
1877PH/53 This is related to PH/52, but is more general: for any failing address,
1878 when detailed error information was permitted to be returned to the

1952 function verify_get_ident() calls ip_connect() to connect a socket, but
1953 if the "connect()" function timed out, ip_connect() used to close the
1954 socket. However, verify_get_ident() also closes the socket later, and in
1955 between Exim writes to the log, which may get opened at this point. When
1956 the socket was closed in ip_connect(), the log could get the same file
1957 descriptor number as the socket. This naturally causes chaos. The fix is
1958 not to close the socket in ip_connect(); the socket should be closed by
1959 the function that creates it. There was only one place in the code where
1960 this was missing, in the iplookup router, which I don't think anybody now

1980PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
1981
1982 (1) Generate an error if the third argument for the ${prvs expansion is
1983 not a single digit.
1984
1985 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1986 string.
1987
1988 (3) Reset the variables that are obtained from the first argument of
1989 ${prvscheck and used in the second argument before leaving the code,
1990 because their memory is reclaimed, so using them afterwards may do
1991 silly things.
1992
1993 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1994 one (it's much easier than Tom thought :-).
1995
1996 (5) Because of (4), we can now allow for the use of $prvscheck_result
1997 inside the third argument.

2017PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2018 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2019 not being looked up in the rDNS to get a host name, Exim was showing the
2020 IP address twice in Received: lines, even though the IP addresses were
2021 identical. For example:
2022
2023 Received: from [1.2.3.4] (helo=[1.2.3.4])
2024
2025 However, if the real host name was known, it was omitting the HELO data
2026 if it matched the actual IP address. This has been tidied up so that it
2027 doesn't show the same IP address twice.

2059 warnings). In the case of bounce messages for non-SMTP mesages, there was
2060 also a typo: it was using "Auto_submitted" (underscore instead of
2061 hyphen). Since every message generated by Exim is necessarily in response
2062 to another message, thes have all been changed to:
2063
2064 Auto-Submitted: auto-replied
2065
2066 in accordance with these statements in the RFC:
2067
2068 The auto-replied keyword:

2071 message by an automatic process,

2118 the IP address, check_host() was doing a simple string comparison with
2119 addresses acquired from the DNS when checking that the found name did
2120 have the original IP as one of its addresses. Since any found IPv6
2121 addresses are likely to be in abbreviated form, the comparison could
2122 fail. Luckily, there already exists a function for doing the comparison
2123 by converting both addresses to binary, so now that is used instead of
2124 the text comparison.

2421PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2422 with the definition in sysexits.h (which is #included earlier).
2423 Fortunately, Exim does not actually use EX_OK. The code used to try to
2424 preserve the sysexits.h value, by assumimg that macro definitions were
2425 scanned for macro replacements. I have been disabused of this notion,
2426 so now the code just undefines EX_OK before #including unistd.h.

2431 This seems wrong - if the receiver was accepting one byte at a time it
2432 would take for ever. The timeout is now adjusted when this happens. It
2433 doesn't have to be particularly precise.

2642PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2643 that changes the way the GnuTLS parameters are stored in the cache file.
2644 The new format can be generated externally. For backward compatibility,
2645 if the data in the cache doesn't make sense, Exim assumes it has read an
2646 old-format file, and it generates new data and writes a new file. This
2647 means that you can't go back to an older release without removing the
2648 file.
2649
2650PH/03 A redirect router that has both "unseen" and "one_time" set does not
2651 work if there are any delivery delays because "one_time" forces the
2652 parent to be marked "delivered", so its unseen clone is never tried
2653 again. For this reason, Exim now forbids the simultaneous setting of
2654 these two options.
2655
2656PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2657 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2658 entry if you want to know the details. The fix, however, neglected to
2659 consider the case when local delivery batching is involved. The test for
2660 "previously delivered" was not happening when checking to see if an
2661 address could be batched with a previous (undelivered) one; under
2662 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2663 address.

2668PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =

2670 In particular, this caused confusion with an attempt to use "verify =
2671 reverse_host_lookup/defer_ok". An error is now given when options are
2672 supplied for verify items that do not have them. (Maybe reverse_host_
2673 lookup should have a defer_ok option, but that's a different point.)

2675PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2728 the file with the wrong ownership). There was no test for failure of this
2729 fork() call, which would lead to the process getting stuck as it waited
2730 for a non-existent subprocess. Forks do occasionally fail when resources

2751PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it

2753 understands it better than I do:
2754
2755 "Here's what I see happening with three configured cyrus_sasl
2756 authenticators configured (plain, login, cram-md5):
2757
2758 On startup auth_cyrus_sasl_init() gets called for each of these.
2759 This means three calls to sasl_listmech() without a specified mech_list.
2760 => SASL tests which mechs of all available mechs actually work
2761 => three warnings about OTP not working
2762 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2763
2764 With the patch, sasl_listmech() also gets called three times. But now
2765 SASL's mech_list option is set to the server_mech specified in the the
2766 authenticator. Or in other words, the answer from sasl_listmech()
2767 gets limited to just the mech you're testing for (which is different
2768 for each call.)
2769 => the return list contains just 'plain' or 'login', 'cram-md5' or
2770 nothing depending on the value of ob->server_mech.
2771

2806 . Two addresses routed to the same list of hosts;

2809 . First host gives temporary error to second address;
2810 . Second host offers TLS and a TLS session is established;
2811 . Second host accepts second address.

PH
2838PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2839 the grounds that routing the same address twice would always produce the
2840 same answer. This might have been true once, but it is certainly no
2841 longer true now. Routing a child address may depend on the previous
2842 routing that produced that child. Some complicated redirection strategies
2843 went wrong when messages had multiple recipients, and made Exim's
2844 behaviour dependent on the order in which the addresses were given.
2845
2846 I have moved the duplicate checking until after the routing is complete.
2847 Exim scans the addresses that are assigned to local and remote
2848 transports, and removes any duplicates. This means that more work will be
2849 done, as duplicates will always all be routed, but duplicates are
2850 presumably rare, so I don't expect this is of any significance.
2851
2852 For deliveries to pipes, files, and autoreplies, the duplicate checking
2853 still happens during the routing process, since they are not going to be
2854 routed further.

2860 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2861 blindly assumes that writes won't block so it may never time out."

2883 (e) A message specified by the cannot_route_message router option.
2884
2885 In these cases only, Exim does include the error details in bounce and
2886 warning messages. There are also a few cases where bland messages such
2887 as "unrouteable address" or "local delivery error" are given.

2898 successful delivery. Such timeouts include transport filter timeouts. For
2899 consistency with the overall process timeout, these timeouts are now
2900 treated as errors, giving rise to delivery failures by default. However,
2901 there is now a new Boolean option for the pipe transport called
2902 timeout_defer, which, if set TRUE, converts the failures into defers for
2903 both kinds of timeout. A transport filter timeout is now identified in

2913A note about Exim versions 4.44 and 4.50
2914----------------------------------------
2915
2916Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2917changes of various kinds. As a consequence, a big documentation update was
2918needed. This delayed the release for rather longer than seemed good, especially
2919in the light of a couple of (minor) security issues. Therefore, the changes
2920that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2921release. So 4.44 and 4.50 are in effect two different branches that both start
2922from 4.43.
2923
2924I have left the 4.50 change log unchanged; it contains all the changes since
29254.43. The change log for 4.44 is below; many of its items are identical to
2926those for 4.50. This seems to be the most sensible way to preserve the
2927historical information.

PH
2945 5. There are several places where Exim runs a non-Exim command in a
2946 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2947 was being done only for the command run by the queryprogram router. It is
2948 now done for all such subprocesses. The other cases are: ${run, transport
2949 filters, and the commands run by the lmtp and pipe transports.

2951 6. Added CONFIGURE_GROUP build-time option.
2952
2953 7. Some older OS have a limit of 256 on the maximum number of file
2954 descriptors. Exim was using setrlimit() to set 1000 as a large value
2955 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2956 systems. I've change it so that if it can't get 1000, it tries for 256.

2958 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2959 was an oversight, and furthermore, ever since the addition of extra
2960 controls (e.g. 4.43/32), the checks on when to allow different forms of
2961 "control" were broken. There should now be diagnostics for all cases when a
2962 control that does not make sense is encountered.

300322. $host_address is now set to the target address during the checking of
3004 ignore_target_hosts.
3005
300623. When checking ignore_target_hosts for an ipliteral router, no host name was
3007 being passed; this would have caused $sender_host_name to have been used if
3008 matching the list had actually called for a host name (not very likely,
3009 since this list is usually IP addresses). A host name is now passed as
3010 "[x.x.x.x]".
3011
7d468ab8
PH
301224. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3013 code that specifies a non-restarting handler (typically sigaction() in
3014 modern systems) in an attempt to fix a rare and obscure crash bug.
3015
301625. Narrowed the window for a race in the daemon that could cause it to ignore
3017 SIGCHLD signals. This is not a major problem, because they are used only to
3018 wake it up if nothing else does.
3019
62c0818f
PH
302026. A malformed maildirsize file could cause Exim to calculate negative values
3021 for the mailbox size or file count. Odd effects could occur as a result.
3022 The maildirsize information is now recalculated if the size or filecount
3023 end up negative.
3024
26034054
PH

PH
303029. In an address list, if the pattern was not a regular expression, an empty
3031 subject address (from a bounce message) matched only if the pattern was an
3032 empty string. Non-empty patterns were not even tested. This was the wrong
3033 because it is perfectly reasonable to use an empty address as part of a
3034 database query. An empty address is now tested by patterns that are
3035 lookups. However, all the other forms of pattern expect the subject to
3036 contain a local part and a domain, and therefore, for them, an empty
3037 address still always fails if the pattern is not itself empty.
3038
d8ef3577
PH
303930. Exim went into a mad DNS loop when attempting to do a callout where the
3040 host was specified on an smtp transport, and looking it up yielded more
3041 than one IP address.
3042
5cb8cbc6
PH
304331. Re-factored the code for checking spool and log partition space into a
3044 function that finds that data and another that does the check. The former
3045 is then used to implement four new variables: $spool_space, $log_space,
3046 $spool_inodes, and $log_inodes.
3047
14702f5b
PH
304832. The RFC2047 encoding function was originally intended for short strings
3049 such as real names; it was not keeping to the 75-character limit for
3050 encoded words that the RFC imposes. It now respects the limit, and
3051 generates multiple encoded words if necessary. To be on the safe side, I
3052 have increased the buffer size for the ${rfc2047: expansion operator from
3053 1024 to 2048 bytes.
3054
063b1e99
PH
305533. It is now permitted to omit both strings after an "if" condition; if the
3056 condition is true, the result is "true". As before, when the second string
3057 is omitted, a false condition yields an empty string. This makes it less
3058 cumbersome to write custom ACL and router conditions.
3059
652e1b65
PH
306034. Failure to deliver a bounce message always caused it to be frozen, even if
3061 there was an errors_to setting on the router. The errors_to setting is now
3062 respected.
3063
6f0c9a4f
PH
306435. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3065 canonical form (fully expanded) before being placed in
3066 $sender_host_address.
3067
33397d19
PH
306836. The table in the code that translates DNS record types into text (T_A to
3069 "A" for instance) was missing entries for NS and CNAME. It is just possible
3070 that this could have caused confusion if both these types were looked up
3071 for the same domain, because the text type is used as part of Exim's
3072 per-process caching. But the chance of anyone hitting this buglet seems
3073 very small.
3074
7bb56e1f
PH
307537. The dnsdb lookup has been extended in a number of ways.
3076
3077 (1) There is a new type, "zns", which walks up the domain tree until it
3078 finds some nameserver records. It should be used with care.
3079
ea3bc19b
PH
3080 (2) There is a new type, "mxh", which is like "mx" except that it returns

3110 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3111 < 0 before doing a fflush(). This bug looks as though it goes back to the

313752. Exim crashed if a remote delivery caused a very long error message to be
3138 recorded - for instance if somebody sent an entire SpamAssassin report back
3139 as a large number of 550 error lines. This bug was coincidentally fixed by
3140 increasing the size of one of Exim's internal buffers (big_buffer) that
3141 happened as part of the Exiscan merge. However, to be on the safe side, I
3142 have made the code more robust (and fixed the comments that describe what
3143 is going on).

PH
315054. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3151 patch that reportedly fixes this has been added. I am not expert enough to
3152 create a test for it. This is what the patch creator wrote:
3153
3154 "I found a little strange behaviour of ldap code when working with
3155 Windows 2003 AD Domain, where users was placed in more than one
3156 Organization Units. When I tried to give exim partial DN, the exit code
3157 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3158 But simultaneously result of request was absolutely normal ldap result,
3159 so I produce this patch..."
3160
3295e65b
PH
3161 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3162 REFERENCE, so I have modified the code to exclude the patch when that macro
3163 is not defined.

PH
317658. The exicyclog utility now does better if the number of log files to keep
3177 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3178

PH
317959. Two changes related to the smtp_active_hostname option:
3180
3181 (1) $smtp_active_hostname is now available as a variable.
3182 (2) The default for smtp_banner uses $smtp_active_hostname instead
3183 of $primary_hostname.

PH
318560. The host_aton() function is supposed to be passed a string that is known
3186 to be a valid IP address. However, in the case of IPv6 addresses, it was
3187 not checking this. This is a hostage to fortune. Exim now panics and dies
3188 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3189 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3190 components; fortuitously, this particular loophole had already been fixed
3191 by change 4.50/55 above.
3192
3193 If there are any other similar loopholes, the new check in host_aton()
3194 itself should stop them being exploited. The report I received stated that
3195 data on the command line could provoke the exploit when Exim was running as
3196 exim, but did not say which command line option was involved. All I could
3197 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3198 running as the user.

3200
320161. There was a buffer overflow vulnerability in the SPA authentication code
3202 (which came originally from the Samba project). I have added a test to the
3203 spa_base64_to_bits() function which I hope fixes it.

320662. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3207 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3208

PH
320963. The daemon start-up calls getloadavg() while still root for those OS that
3210 need the first call to be done as root, but it missed one case: when
3211 deliver_queue_load_max is set with deliver_drop_privilege. This is
3212 necessary for the benefit of the queue runner, because there is no re-exec
3213 when deliver_drop_privilege is set.
3214
86b8287f
PH
321564. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3216 This has been fixed.
3217
60dc5e56
PH
321865. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3219 was in use, was not putting the data itself into the right store pool;
3220 consequently, it could be overwritten for a subsequent message in the same
3221 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3222 the caching.)
3223

PH
322466. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3225
a5a28604
PH
322667. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3227 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3228 the function were treating the return as a boolean value, which happened to
3229 work because 0=false and not-0=true, but is not correct code.
3230
7e634d24
PH
323168. The host_aton() function was not handling scoped IPv6 addresses (those
3232 with, for example, "%eth0" on the end) correctly.
3233
3e11c26b
PH
323469. Fixed some compiler warnings in acl.c for the bitmaps specified with
3235 negated items (that is, ~something) in unsigned ints. Some compilers
3236 apparently mutter when there is no cast.
3237
6729cf78
PH
323870. If an address verification called from an ACL failed, and did not produce a
3239 user-specific message (i.e. there was only a "system" message), nothing was
3240 put in $acl_verify_message. In this situation, it now puts the system
3241 message there.
3242
00f00ca5
PH
324371. Change 4.23/11 added synchronization checking at the start of an SMTP
3244 session; change 4.31/43 added the unwanted input to the log line - except
3245 that it did not do this in the start of session case. It now does.
3246
c9bdd01c
PH
324772. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3248 This is wrong and can cause the other end to generate a synchronization
3249 error if it is another Exim or anything else that does the synchronization
3250 check. A QUIT command is no longer sent after a timeout.
3251

PH
325273. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3253 during host lookups.
3254

PH
325574. The defer_ok option of callout verification was not working if it was used
3256 when verifying addresses in header lines, that is, for this case:
3257
3258 verify = header_sender/callout=defer_ok
3259
76a2d7ba
PH
326075. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3261 those file descriptors could be used for SMTP connections. If anything
3262 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3263 could be sent to the SMTP client, causing chaos. The daemon now opens
3264 stdin, stdout, and stderr to /dev/null when it puts itself into the
3265 background.
3266
326776. Arrange for output from Perl's "warn" command to be written to Exim's main
3268 log by default. The user can override this with suitable Perl magic.
3269
04f7d5b9
PH
327077. The use of log_message on a "discard" ACL verb, which is supposed to add to
3271 the log message when discard triggers, was not working for the DATA ACL or
3272 for the non-SMTP ACL.
3273
bc60667e
PH
327478. Error message wording change in sieve.c.
3275
bb6e88ff
PH
327679. If smtp_accept_max_per_host was set, the number of connections could be
3277 restricted to fewer than expected, because the daemon was trying to set up
3278 a new connection before checking whether the processes handling previous
3279 connections had finished. The check for completed processes is now done
3280 earlier. On busy systems, this bug wouldn't be noticed because something
3281 else would have woken the daemon, and it would have reaped the completed
3282 process earlier.
3283
1e70f85b
PH
328480. If a message was submitted locally by a user whose login name contained one
3285 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3286 It caused a spool format error. I have fixed the spool reading code. A
3287 related problem was that the "from" clause in the Received: line became
3288 illegal because of the space(s). It is now covered by ${quote_local_part.
3289
329081. Included the latest eximstats from Steve (adds average sizes to HTML Top
3291 tables).

3304----------------------------------------------------
3305See the note above about the 4.44 and 4.50 releases.
3306----------------------------------------------------
3307
3308
3309Exim version 4.44
3310-----------------
3311
3312 1. Change 4.43/35 introduced a bug that caused file counts to be
3313 incorrectly computed when quota_filecount was set in an appendfile
3314 transport
3315
3316 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3317 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3318 place.
3319
3320 3. Give more explanation in the error message when the command for a transport
3321 filter fails to execute.
3322
3323 4. There are several places where Exim runs a non-Exim command in a
3324 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3325 was being done only for the command run by the queryprogram router. It is
3326 now done for all such subprocesses. The other cases are: ${run, transport
3327 filters, and the commands run by the lmtp and pipe transports.
3328
3329 5. Some older OS have a limit of 256 on the maximum number of file
3330 descriptors. Exim was using setrlimit() to set 1000 as a large value
3331 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3332 systems. I've change it so that if it can't get 1000, it tries for 256.
3333
3334 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3335 was an oversight, and furthermore, ever since the addition of extra
3336 controls (e.g. 4.43/32), the checks on when to allow different forms of
3337 "control" were broken. There should now be diagnostics for all cases when a
3338 control that does not make sense is encountered.
3339
3340 7. $recipients is now available in the predata ACL (oversight).
3341
3342 8. Tidy the search cache before the fork to do a delivery from a message
3343 received from the command line. Otherwise the child will trigger a lookup
3344 failure and thereby defer the delivery if it tries to use (for example) a
3345 cached ldap connection that the parent has called unbind on.
3346
3347 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3348 of $address_data from the recipient verification was clobbered by the
3349 sender verification.
3350
335110. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3352 was its contents. (It was OK if the option was not defined at all.)
3353
335411. A "Completed" log line is now written for messages that are removed from
3355 the spool by the -Mrm option.
3356
335712. $host_address is now set to the target address during the checking of
3358 ignore_target_hosts.
3359
336013. When checking ignore_target_hosts for an ipliteral router, no host name was
3361 being passed; this would have caused $sender_host_name to have been used if
3362 matching the list had actually called for a host name (not very likely,
3363 since this list is usually IP addresses). A host name is now passed as
3364 "[x.x.x.x]".
3365
336614. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3367 code that specifies a non-restarting handler (typically sigaction() in
3368 modern systems) in an attempt to fix a rare and obscure crash bug.
3369
337015. Narrowed the window for a race in the daemon that could cause it to ignore
3371 SIGCHLD signals. This is not a major problem, because they are used only to
3372 wake it up if nothing else does.
3373
337416. A malformed maildirsize file could cause Exim to calculate negative values
3375 for the mailbox size or file count. Odd effects could occur as a result.
3376 The maildirsize information is now recalculated if the size or filecount
3377 end up negative.
3378
337917. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3380 support for a long time. Removed HAVE_SYS_VFS_H.
3381
ea3a6f44 338218. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3383
338419. Allow an empty sender to be matched against a lookup in an address list.
3385 Previously the only cases considered were a regular expression, or an
3386 empty pattern.
3387
338820. Exim went into a mad DNS lookup loop when doing a callout where the
3389 host was specified on the transport, if the DNS lookup yielded more than
3390 one IP address.
3391
ea3a6f44
NM
339221. The RFC2047 encoding function was originally intended for short strings
3393 such as real names; it was not keeping to the 75-character limit for
3394 encoded words that the RFC imposes. It now respects the limit, and
3395 generates multiple encoded words if necessary. To be on the safe side, I
3396 have increased the buffer size for the ${rfc2047: expansion operator from
3397 1024 to 2048 bytes.
bbe902f0 3398
ea3a6f44
NM
339922. Failure to deliver a bounce message always caused it to be frozen, even if
3400 there was an errors_to setting on the router. The errors_to setting is now
3401 respected.
bbe902f0
PH
3402
340323. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3404 canonical form (fully expanded) before being placed in
3405 $sender_host_address.
3406
340724. Updated eximstats to version 1.33
3408
ea3a6f44
NM
340925. Include certificate and key file names in error message when GnuTLS fails
3410 to set them up, because the GnuTLS error message doesn't include the name
3411 of the failing file when there is a problem reading it.
bbe902f0
PH
3412
341326. Expand error message when OpenSSL has problems setting up cert/key files.
