The list of unsafe functions currently consists of sprintf, vsprintf,
strcat, strncat and gets.
Subsequently, some existing code needed updating to avoid warnings on
this.
As the UID has to be specified by the user for the FETCH command to work
correctly, added a check to imap_fetch(), although strictly speaking it
is protected by the call from imap_perform().
The option needs to be set on the SSL socket. Setting it on the model
takes no effect. Note that the non-blocking mode is still not enabled
for the handshake because the code is not yet ready for that.
Commit 26eaa83830 introduces the use of S_ISDIR() yet some compilers,
such as MSVC don't support it, so we must define a substitute using
file flags and mask.
Commit f4cc54cb47 (shipped as part of the 7.29.0 release) was a
bug fix that introduced a regression in that while trying to avoid
allowing directory names, it also forbade "special" files like character
devices and more. like "/dev/null" as was used by Oliver who reported
this regression.

If the server hung up the connection without sending a closure alert,
then we'd keep probing the socket for data even though it's dead. Now
we're ready for this situation.

Some state changes would be performed after a failure test that
performed a hard return, whilst others would be performed within a test
for success. Updated the code, for consistency, so all instances are
performed within a success test.
Some state changes would be performed after a failure test that
performed a hard return, whilst others would be performed within a test
for success. Updated the code, for consistency, so all instances are
performed within a success test.
Added imap_custom(), which initiates the custom command processing,
and an associated response handler imap_state_custom_resp(), which
handles any responses by sending them to the client as body data.
All untagged responses with the same name as the first word of the
custom request string are accepted, with the exception of SELECT and
EXAMINE which have responses that cannot be easily identified. An
extra check has been provided for them so that any untagged responses
are accepted for them.
Added imap_parse_custom_request() for parsing the CURLOPT_CUSTOMREQUEST
parameter which URL decodes the value and separates the request from
any parameters - This makes it easier to filter untagged responses
by the request command.
For consistency changed the logic of the imap_state_append_resp()
function to test for an unsucessful continuation response rather than a
succesful one.
The APPEND operation needs to be performed in several steps:
1) We send "<tag> APPEND <mailbox> <flags> {<size>}\r\n"
2) Server responds with continuation respose "+ ...\r\n"
3) We start the transfer and send <size> bytes of data
4) Only now we end the request command line by sending "\r\n"
5) Server responds with "<tag> OK ...\r\n"
This commit performs steps 4 and 5, in the DONE phase, as more
processing is required after the transfer.
Some state changes would be performed after a failure test that
performed a hard return, whilst others would be performed within a test
for success. Updated the code, for consistency, so all instances are
performed within a success test.
Not processing the final FETCH responses was not optimal, not only
because the response code would be ignored but it would also leave data
unread on the socket which would prohibit connection reuse.
A typical FETCH response can be broken down into four parts:
1) "* <uid> FETCH (<what> {<size>}\r\n", using continuation syntax
2) <size> bytes of the actual message
3) ")\r\n", finishing the untagged response
4) "<tag> OK ...", finishing the command
Part 1 is read in imap_fetch_resp(), part 2 is consumed in the PERFORM
phase by the transfer subsystem, parts 3 and 4 are currently ignored.
Added a loop to imap_statemach_act() in which Curl_pp_readresp() is
called until the cache is drained. Without this multiple responses
received in a single packet could result in a hang or delay.
RFC 3501 states that "the client MUST be prepared to accept any response
at all times" yet we assume anything received with "* " at the beginning
is the untagged response we want.
Introduced a helper function that checks whether the input looks like a
response to specified command, so that we may filter the ones we are
interested in according to the current state.
Introduced similar handling to the FETCH responses, where even the
untagged data responses are handled by the response handler of the
individual state.
Removed this pointer to a downloaded bytes counter because it was set in
smtp_init() to point to the same variable the transfer functions keep
the count in (k->bytecount), effectively making the code in transfer.c
"*k->bytecountp = k->bytecount" a no-op.
Removed this pointer to a downloaded bytes counter because it was set in
pop3_init() to point to the same variable the transfer functions keep
the count in (k->bytecount), effectively making the code in transfer.c

From a maintenance point of view the code reads better to view tagged
responses, then untagged followed by continuation responses.
Additionally, this matches the order of responses in POP3.
Updated the mailbox variable to correctly reflect it's purpose. The
name mailbox was a leftover from when IMAP and POP3 support was
initially added to curl.
Updated the FETCH command to send the UID and SECTION parsed from the
URL. By default the BODY specifier doesn't include a section, BODY[] is
now sent whereas BODY[TEXT] was previously sent. In my opinion
retrieving just the message text is rarely useful when dealing with
emails, as the headers are required for example, so that functionality
is not retained. In can however be simulated by adding SECTION=TEXT to
the URL.
Also updated test801 and test1321 due to the BODY change.
Removed user and passwd from the SMTP struct as these cannot be set on
a per-request basis and are leftover from legacy FTP code.
Changed some comments still using FTP terminology.
Removed user and passwd from the POP3 struct as these cannot be set on
a per-request basis and are leftover from legacy FTP code.
Changed some comments still using FTP terminology.
Moved the mailbox and custom request variables from the per-connection
struct pop3_conn to the new per-request struct and fixed references
accordingly.
Created a new IMAP structure and changed the type of the imap proto
variable in connectdata from FTP* to the new IMAP*.
Moved the mailbox variable from the per-connection struct imap_conn to
the new per-request struct and fixed references accordingly.
Moved the clean-up of the mailbox variable from imap_disconnect() to
imap_done() as this variable is allocated in the do phase, yet would
have only been freed only once if multiple selects where preformed
on a single connection.
Always interprets the pointer passed with the CURLOPT_WRITEDATA or
CURLOPT_READDATA options of curl_easy_setopt() as a void pointer in
order to avoid problems in environments where FILE and void pointers
have non-trivial conversion.
Use Curl_pp_moredata() in Curl_pp_multi_statemach() to check if there is
more data to be received, rather than the socket state, as a task could
hang waiting for more data from the socket itself.
A simple function to test whether the PP is not sending and there are
still more data in its receiver cache. This will be later utilized to:
1) Change Curl_pp_multi_statemach() and Curl_pp_easy_statemach() to
not test socket state and just call user's statemach_act() function
when there are more data to process, because otherwise the task would
just hang, waiting for more data from the socket.
2) Allow PP users to read multiple responses by looping as long as there
are more data available and current phase is not finished.
(Currently needed for correct processing of IMAP SELECT responses.)
The attempt to use gai_strerror() or alternative function didn't work as
the 'sock_error' field didn't contain the proper error code. But since
this hasn't been reported and thus isn't really a big deal I decided to
just scrap the whole attempt to output the detailed resolver error and
instead remain with just stating that the resolving of the name failed.
It seems older gcc installations (at least) will cause warnings if we
name a variable 'wait'. Now changed to 'block' instead.

Apple made a number of changes to Xcode 4. The SDKs were moved, the entire
Developer folder was moved, and PowerPC support was removed. The script
will now adapt to those changes and should be future-proofed against
additional changes in case Apple moves the Developer folder ever again.
Also, the minimum OS X version compiler option was removed, so that the
framework can be built against the latest SDK but still run in older cats.
... since they're not used by the easy interface really, I wanted to
remove the association. Also, I unified the pingpong statemachine driver
into a single function with a 'wait' argument: Curl_pp_statemach.
A call to Curl_ssl_connect() was accidentally left in when the SSL/TLS
connection layer was reworked in 7.29. Not only would this cause the
connection to block but had the additional overhead of calling the
non-blocking connect a little bit later.
This function was only used twice, both in places where performance
isn't crucial (socks + if2ip). Removing the use of this function removes
the need to have our private version for systems without it == reduced
amount of code.
Also, in the SOCKS case it is clearly better to fail gracefully rather
than to truncate the results.
This work was triggered by a bug report on the strcal prototype in
strequal.h.
strlcat was added in commit db70cd28 in February 2001!

An ambiguity in the SSLWrite() documentation lead to a bad inference in the
code where we assumed SSLWrite() returned the amount of bytes written to
the socket, when that is not actually true; it returns the amount of data
that is buffered for writing to the socket if it returns errSSLWouldBlock.
Now darwinssl_send() returns CURLE_AGAIN if data is buffered but not written.
Reference URL: http://curl.haxx.se/mail/lib-2013-02/0145.html
Reworked the pp->endofresp() function so that the conndata, line and
line length are passed down to it just as with Curl_client_write()
rather than each implementation of the function having to query
these values.
Additionally changed the int return type to bool as this is more
representative of the function's usage.
Corrected the order of the upgrade_tls() functions and moved the handler
upgrade and getsock() functions out from the middle of the state related
functions.
Corrected the order of the pop3_state_capa() / imap_state_capability()
and the pop3_state_capa_resp() / imap_state_capability_resp() functions
to match the execution order.
Added honoring of the tls_supported flag when starting a TLS upgrade
rather than unconditionally attempting it. If the use_ssl flag is set
to CURLUSESSL_TRY and the server doesn't support TLS upgrades then the
connection will continue to authenticate. If this flag is set to
CURLUSESSL_ALL then the connection will complete with a failure as it
did previously.

Added sending of initial CAPABILITY command before STARTTLS is sent.

Follow up fix to commit 62bd217464 to cater for servers that don't
respond with a 250 in their EHLO responses. Additionally updated the
SMTP tests to respond with a 250 response code as per RFC5321.
Fixed the SASL capability detection to include the space character
before the authentication mechanism list. Otherwise a capability such
as SASLSOMETHING would be interpreted as enabling SASL and potentially
trying to identify SOMETHING as a mechanism.
Previously if a problem was found with one of the server's certificates,
we'd log an OSStatus for the end user to look up. Now we explain what
was wrong with the site's certificate chain. Also un-did part of the
previous commit where the code wouldn't catch errSSLServerAuthCompleted
if built under Leopard.
Fixed a small issue where smtp_endofresp() would look for capabilities
in the description part of a failure response. In theory a server
shouldn't respond with SIZE or AUTH in an EHLO command's failure
response but if it did then capabilities would be unnecessarily set
before eventually failing.
Renamed the authstate1 and authstate2 variables in imap_authenticate()
as the old name was a left over from when there was only one state
variable which was named due to a clash with the state() function.
Additionally this provides consistency with the smtp module.

'dup_domain.tbyte_ptr' looks to be freed in Curl_ntlm_sspi_cleanup() via
'ntlm->identity.Domain'. But I see no freeing of 'dup_domain.tchar_ptr'.
This bug report properly identified that when doing SMTP and aborting
the transfer with a callback, it must be considered aborted prematurely
by the code to avoid QUIT etc to be attempted as that would cause a
hang.
The new test case 1507 verifies this behavior.

It turns out that Leopard (OS X 10.5) doesn't have constants for the ECDH
ciphers in its headers, so the cases for them have been taken out of the
build when building under Leopard. Also added a standard function for
getting a string description of a SecCertificateRef.
Changed the SMTP_AUTH_PASSWD state constant to SMTP_AUTH_LOGIN_PASSWD to
better describe the state as the second part of an AUTH LOGIN command,
as well as for consistency with the imap and pop3 modules.
Introduced detection of the SASL-IR capability, in order to add support
for sending the initial response with the AUTHENTICATE command, as per
RFC4959.
Updated the automatic response tag generation to follow the examples
given in RC3501, which list a 4 character string such as A001, A002,
etc.
As a unique identifier should be generated for each command the string
generation is based on the connection id and the incrementing command
id.
When negotiating SASL DIGEST-MD5 authentication, the function
Curl_sasl_create_digest_md5_message() uses the data provided from the
server without doing the proper length checks and that data is then
appended to a local fixed-size buffer on the stack.
This vulnerability can be exploited by someone who is in control of a
server that a libcurl based program is accessing with POP3, SMTP or
IMAP. For applications that accept user provided URLs, it is also
thinkable that a malicious user would feed an application with a URL to
a server hosting code targetting this flaw.

config_h.com is a new file that generates a config.h file based on the
curl_config.h.in file and a quick scan of the configure script. This is
actually a generic procedure that is shared with other VMS packages.
The existing pre-built config-vms.h had over 100 entries that were not
correct and in some cases conflicted with the build options available in
the build_vms.com.
generate_config_vms_h_curl.com is a helper procedure to the
config_h.com. It covers the cases that the generic config_h.com is not
able to figure out, and accepts input from the build_vms.com procedure.
build_curlbuild_h.com is a new file to generate the curlbuild.h file
that Curl is now using when it is using a curl_config.h file.
post-config-vms.h is a new file that is needed to provide VMS specific
definitions, and most of them need to be set before the system header
files are included.
The VMS build procedure is fixed:
1. Fixed to link in the correct HP ssl library.
2. Fixed to detect if HP Kerberos is installed.
3. Fixed to detect if HP LDAP is installed.
4. Fixed to detect if gnv$libzshr is installed.
5. Simplified the input parameter parsing to not use a loop.
6. Warn that 64 bit pointer option support is not complete
in comments.
7. Default to IEEE floating if platform supports it so
resulting libcurl will be compatible with other
open source projects on VMS.
8. Default to LARGEFILE if platform supports it.
9. Default to enable SSL, LDAP, Kerberos, libz
if the libraries are present.
10. Build with exact case global symbols for libcurl.
11. Generate linker option file needed.
12. Compiler list option only commonly needed items.
13. fulllist option for those who really want it.
14. Create debug symbol file on Alpha, IA64.
By doing this unconditionally, we infer a simpler and more defined
behavior. This also has the upside that test 1021 no longer fails for me
even if I run with valgrind.
Also fixed some wrong comments.
According KB975858 this flag may cause problems on Windows 7 and
Windows Server 2008 R2 systems. Extended error information is not
currently used by libcurl and therefore not a requirement.
The flag may improve the SSL-connection shutdown in case of an
error. This means it might be a good improvement in the future.

This commit fixes a regression introduced in 052a08ff.
NSS caches certs/keys returned by the SSL_GetClientAuthDataHook callback
and if we connect second time to the same server, the cached cert/key
pair is used. If we use multiple client certificates for different
paths on the same server, we need to clear the session cache to force
NSS to call the hook again. The commit 052a08ff prevented the session
cache from being cleared if a client certificate from file was used.
The condition is now fixed to cover both cases: consssl->client_nickname
is not NULL if a client certificate from the NSS database is used and
connssl->obj_clicert is not NULL if a client certificate from file is
used.

This commit renames lib/setup.h to lib/curl_setup.h and
renames lib/setup_once.h to lib/curl_setup_once.h.
Removes the need and usage of a header inclusion guard foreign
to libcurl. [1]
Removes the need and presence of an alarming notice we carried
in old setup_once.h [2]
----------------------------------------
1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard
up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H,
this single inclusion guard is enough to ensure that inclusion of
lib/setup_once.h done from lib/setup.h is only done once.
Additionally lib/setup.h has always used __SETUP_ONCE_H macro to
protect inclusion of setup_once.h even after commit ec691ca3, this
was to avoid a circular header inclusion triggered when building a
c-ares enabled version with c-ares sources available which also has
a setup_once.h header. Commit ec691ca3 exposes the real nature of
__SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard
foreign to libcurl belonging to c-ares's setup_once.h
The renaming this commit does, fixes the circular header inclusion,
and as such removes the need and usage of a header inclusion guard
foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl.
2 - Due to the circular interdependency of old lib/setup_once.h and the
c-ares setup_once.h header, old file lib/setup_once.h has carried
back from 2006 up to now days an alarming and prominent notice about
the need of keeping libcurl's and c-ares's setup_once.h in sync.
Given that this commit fixes the circular interdependency, the need
and presence of mentioned notice is removed.
All mentioned interdependencies come back from now old days when
the c-ares project lived inside a curl subdirectory. This commit
removes last traces of such fact.

2. added -f option to force re-processing the file. Useful for
debugging/testing the process.
3. added support for output to '-' (stdout), allowing the output to be
piped.
4. All progress and error messages go to STDERR rather than STDOUT (3)
5. The script opened and closed the output file many times
unnecessarily. It now opens it once, does the output and closes it.
6. Backup of the input files happens after successful processing, not
before.
7. The output is written to a temporary file, and renamed to the
requested name after backup - this greatly reduces the window where the
file can be seen partially written.
8. all die calls have a \n at the end to suppress perl's traceback - the

... on Snow Leopard and Lion
Snow Leopard introduced the SSLSetSessionOption() function, but it
doesn't disable peer verification as expected on Snow Leopard or
Lion (it works as expected in Mountain Lion). So we now use sysctl()
to detect whether or not the user is using Snow Leopard or Lion,
