Implement user/password authentication and domainname address type. Change callers accordingly. (_assuan_sock_connect_byname): New. (assuan_sock_connect_byname): New. * tests/socks5.c (main): Add options --byname, --user, and --pass. -- The assuan_sock_connect_byname may eventually be extended to work without Tor or SOCKS by using getaddrinfo. Or we move that all to libgpgrt (aka libgpg-error). Signed-off-by: Werner Koch <[email protected]>

(AM_LDFLAGS): Add -no-install for easier debugging. -- A future extension might be a new assuan_sock_direct_connect call takes the hostname as a string and returns a new socket. This allows the proxy to do the resolving. However, in the long term these socket wrapper should be moved to libgpgrt (aka libgpg-error). Signed-off-by: Werner Koch <[email protected]>

| | | | | | | | | | | | * src/assuan-defs.h (wipememory2, wipememory): New. Taken from GnuPG. * src/assuan.c (assuan_release): Wipe the context. -- The assuan context has buffers which may carry senitive information. These buffers could be wiped out with each flush but that is too expensive. Thus we only wipe them when freeing the context. Signed-off-by: Werner Koch <[email protected]>
* Add assuan_sock_set_flag and assuan_sock_get_flag.Werner Koch2015-06-304-8/+63

(assuan_sock_get_flag): New. * src/libassuan.def: Add them. * src/libassuan.vers: Add them. -- These new functions are intended for a Cygwin socket emulation.

| | | | | | | * src/assuan-defs.h (_assuan_error): Use error source Assuan if no CTX is given. Signed-off-by: Werner Koch <[email protected]>
* Do not segv if NULL is passed for CTX in sendfd and receivefd.Werner Koch2015-06-262-2/+8
| | | | | | | | | | | * src/assuan-buffer.c (assuan_sendfd): Check that CTX is not NULL. (assuan_receivefd): Ditto. -- This change is to align the behaviour with that of assuan_send_data. Suggested-by: Andre Heinecke. Signed-off-by: Werner Koch <[email protected]>
* w32: Use -static-libgcc to avoid linking to libgcc_s_sjlj-1.dll.Werner Koch2015-01-301-0/+4
| | | | | | | | | | | | | | | | * src/Makefile.am (extra_ltoptions): New. (libassuan_la_LDFLAGS): Use it. -- Since gcc 4.8 there is a regression in that plain C programs may link to libgcc_s.a which has a dependency on libgcc_s_sjlj.dll. This is for example triggered by using long long arithmetic on a 32 bit Windows (e.g symbol __udivdi3). This patch does not change anything right now but we add it anyway in case long long will ever be used. Signed-off-by: Werner Koch <[email protected]>
* Require the use of automake 1.14Werner Koch2015-01-281-1/+1
| | | | | | * configure.ac (AM_INIT_AUTOMAKE): Add serial-tests. * src/Makefile.am (INCLUDES): Rename to AM_CPPFLAGS and remove the nonexistent ../include/.

| | | | | | | | | | | | * src/assuan-socket-connect.c (assuan_socket_connect_fd): Map fd to assuan_fd_t. -- This function is actually not used by GnuPG. The function should have taken an assuan_fd but given that it did not we use our usual mapping from Windows libc fds to an assuan fd. Signed-off-by: Werner Koch <[email protected]>
* Fix gcc warning about unused values.Werner Koch2015-01-281-23/+24
| | | | | | | | | | * src/debug.h: Remove traling ", 0" expression part where not useful. -- gcc 4.9 detected this. Probably taken from gpgme but used differently. Signed-off-by: Werner Koch <[email protected]>
* Fix WSAEADDRINUSE EADDRINUSE mismatch.Werner Koch2015-01-272-3/+5
| | | | | | | | | | | | * src/w32-sock-nonce.inc.h (EADDRINUSE): Avoid redefining. * src/assuan-socket.c (_assuan_sock_bind): Set error to EADDRINUSE. -- With the latest mingw-w64 EADDRINUSE is defined but to a different value than WSAEADDRINUSE. We need to use EADDRINUSE becuase that is what applications expect. Signed-off-by: Werner Koch <[email protected]>

* Do not allow LFs in the redirected name.Werner Koch2014-11-281-1/+8
| | | | | | | | * src/assuan-socket.c (eval_redirection): Stop parsing at the first LF. -- Avoiding LFs in file names is better for logging.
* Implement socket file redirection.Werner Koch2014-11-285-22/+244
| | | | | | | | | | | | | | | | | | | | | * configure.ac (AC_CHECK_FUNC): Check for stat. * src/assuan-socket.c (SUN_LEN): Add. (eval_redirection): New. (_assuan_sock_connect) [!W32]: Implement socket file redirection. (_assuan_sock_set_sockaddr_un): New. (assuan_sock_set_sockaddr_un): New. -- This feature is useful to allow sockets with standard names even on file system which do not supports socket and to help with shared home directories. For example to use GnuPG 2.1 with shared home directories one will be abale to do: rm ~/.gnupg/S.gpg-agent || true printf "%%Assuan%%\nsocket=${HOME}/.gnupg/S.gpg-agent_${HOSTNAME}\n" \ > ~/.gnupg/S.gpg-agent Signed-off-by: Werner Koch <[email protected]>
* w32: Remove I/O delays due to our 100ms delay after an EAGAIN.Werner Koch2014-11-072-0/+46
| | | | | | | * src/system-w32.c (__assuan_read): Retry using select. Map WSAECONNRESET to EPIPE. (__assuan_write): Retry using select. * src/assuan-buffer.c (readline) [W32]: Return EOF instead of EPIPE.

| | | | | | | | | * src/context.c (assuan_set_error): Do not pass NULL for %s in the trace function. -- This likely fixes GnuPG-bug-id: 1659
* Avoid a vasprintf call if tracing has not been enabled.Werner Koch2014-06-301-12/+16
| | | | * src/debug.c (_assuan_debug): Check wether CAT want to be logged.
* Fix NULL deref when tracing is enabled and malloc fails.Werner Koch2014-04-162-7/+12
| | | | | | | | | * src/debug.h (TRACE_ERR): Check CTX before a deref. * src/assuan-defs.h (_assuan_error): Turn into an inline function and check CTX before a deref. -- Found by Hans-Christoph Steiner with cppcheck.
* Changes to support W64.Werner Koch2013-06-192-8/+11
| | | | | | | | | | | | * configure.ac (have_dosish_system): Set for W64. * src/assuan-defs.h (SOCKET2HANDLE, HANDLE2SOCKET): Add versions for W64. * src/assuan-handler.c (assuan_command_parse_fd) [W64]: Use strtoull to parse an FD. -- Note that these changes are not complete but merely sufficient to allow building of GpgEX.
* Add assuan_check_version and ASSUAN_VERSION_NUMBER.Werner Koch2013-02-226-22/+144
| | | | | | | | | | | | | | | | | | | | * src/assuan.c (assuan_check_version): New. (digitp, parse_version_number, parse_version_string) (compare_versions): New. Taken from libksba. * configure.ac (VERSION_NUMBER): New ac_subst. * src/Makefile.am (assuan.h): Pass VERSION and VERSION_NUMBER to mkheader. * src/assuan.h.in (ASSUAN_VERSION, ASSUAN_VERSION_NUMBER): New macros. (assuan_check_version): New prototype. * src/libassuan.def, src/libassuan.vers: Add assuan_check_version. * src/mkheader.c (write_special, main): Support version and version_number. * tests/version.c: New. * tests/Makefile.am (TESTS): Add version. -- All our other libs have a version number check, thus we should have one in Libassuan as well.
* w32: Fix header inclusion order for newer toolchain.Werner Koch2013-02-221-13/+12
| | | | | | | | * src/system-w32.c: Do not include windows.h here. -- winsock2.h must now be included before windows.h. This is already properly handled by assuan-defs.h.
* Beautify the BUILD_TIMESTAMP and put it into the binary.Werner Koch2013-02-221-1/+3
| | | | | | | | | | | | | * configure.ac (BUILD_TIMESTAMP): Use an ISO date string on all platforms and ac_define it. * src/sysutils.c (_assuan_sysutils_blurb): But revision and build date into the binary. -- An ISO date is for sure better than the old C standard time format. An almost all platforms this should work. We don't print the seconds to be compatible with the way we did in on Windows. However we print in UTC.
* w32ce: Adjust to changed API and make it build again.Werner Koch2013-02-221-22/+22
| | | | | | | | | | | * src/system-w32ce.c (__assuan_write, __assuan_recvmsg) (__assuan_sendmsg, __assuan_waitpid): Make functions global. * tests/ce-server.c: Fix syntax error (s/#else/#endif) -- This patch fixes some cruft which has accidentally been introduced over time. The code builds, but due to a lack of ready to use CE box, I was not able to test it.
* Modernize release version management.Werner Koch2013-02-221-3/+3
| | | | | | * configure.ac: Update to modern git version checking. Remove svn support. * src/versioninfo.rc.in: Update copyright years.
* Make assuan_transact more robust against inquiry errors.Werner Koch2013-02-071-10/+19
| | | | | * src/client.c (assuan_transact): Send an CAN after an error return from the inquiry callback.
* Check for getpeerucred().Ben Kibbey2012-11-261-5/+21
| | | | | | | * configure.ac: check for getpeerucred() which (Open)Solaris/SunOS uses. * src/assuan-socket-server.c (accept_connection_bottom): make use of getpeerucred().
* Support LOCAL_PEEREID (NetBSD) and getpeereid() (FreeBSD)Ben Kibbey2012-11-211-0/+21
| | | | | | | | | | | | | | | | | | * configure.ac: check for LOCAL_PEEREID and getpeereid(). * src/assuan-socket-server.c (accept_connection_bottom): make use of LOCAL_PEEREID and getpeereid(). -- For use with assuan_get_peercred(). Note that getpeereid() does not set the PID member. LOCAL_PEEREID is checked before getpeereid() since NetBSD has both of these. SO_PEERCRED is still checked first. [Second revision] This revision adds support for LOCAL_PEEREID which NetBSD uses. Its tested against NetBSD 6.0 and may work without problems with earlier versions. FreeBSD uses getpeereid() which does not have PID support. Recent OpenBSD versions do support SO_PEERCRED and old versions have getpeereid() but also may have LOCAL_PEEREID (not sure).

* Fix npth port file handle use.Marcus Brinkmann2012-01-243-12/+30
| | | | | | | | | * assuan.h.in (ASSUAN_SYSTEM_NPTH_IMPL): Use npth_unprotect and npth_protect with actual assuan functions instead of npth wrappers. * libassuan.def: Add __assuan_read, __assuan_write, __assuan_sendmsg, __assuan_recvmsg, __assuan_waitpid exports. * system-w32.c (__assuan_read, __assuan_write, __assuan_sendmsg, __assuan_recvmsg, __assuan_waitpid): Make non-static.

* Fix assuan_get_pid for pipe servers.Werner Koch2011-12-131-19/+24
| | | | | | | | | | | At some point in the past we introduced a regression in that the client of a pipe server received its own pid and not the pid of the server. * src/assuan-pipe-connect.c (struct at_pipe_fork) (struct at_socketpair_fork): Add PARENT_PID. (at_pipe_fork_cb, at_socketpair_fork): Use PARENT_PID instead of getpid. (pipe_connect, socketpair_connect): Set PARENT_PID.
