2023-06-15Flush data before clearing the confidential flag.Werner Koch1-1/+3
* src/context.c (assuan_end_confidential): Flush data. -- This is required so that for example gpg-agent won't reveal a password in a log file if requested via get_passphrase --data X X X X (Note that --data is required in any case because the default of returing it with the OK line can't be secured).
2023-05-17w32: Cleaner semantics for PID and Process handle.NIIBE Yutaka1-1/+21
* src/assuan-defs.h (struct assuan_context_s): Introduce SERVER_PROC member. Clarify the use of PROCESS_ID and PID. Introduce assuan_pid_t for internal use of process id or handle. * src/assuan.h.in: Follow the change. * src/assuan.c (assuan_new_ext): Likewise. * src/client.c (_assuan_client_finish): Likewise. * src/assuan-pipe-connect.c (pipe_connect): Likewise. * src/server.c (_assuan_server_finish): Likewise. * src/system-posix.c: Likewise. * src/system-w32.c: Likewise. * src/system.c: Likewise. * src/assuan-pipe-server.c (assuan_init_pipe_server) [HAVE_W32_SYSTEM]: Exclude the use of _assuan_pipe_connect_pid. * src/assuan-socket-server.c (accept_connection_bottom) [HAVE_W32_SYSTEM]: Exclude the use of the member peercred.pid. * src/assuan-socket.c (_assuan_sock_check_nonce): Support Cygwin Unix domain emulation for having valid client process ID. * src/context.c (assuan_get_pid): Clarify the use cases. * src/posix-types.inc.h, src/w32-types.inc.h: Introduce assuan_pid_t. -- GnuPG-bug-id: 6487 Signed-off-by: NIIBE Yutaka <[email protected]>

2022-05-25client: Handle inquiry from server with CONFIDENTIAL.NIIBE Yutaka1-0/+2
* src/assuan-defs.h (struct assuan_context_s): Add new flags, in_inq_cb and confidential_inquiry. * src/client.c (assuan_transact): Use the new flags to wipe the outbound buffer for inquiry when CONFIDENTIAL. * src/context.c (assuan_set_flag): When ASSUAN_CONFIDENTIAL is set in inquire callback, set the confidential_inquiry flag. -- GnuPG-bug-id: 5977 Signed-off-by: NIIBE Yutaka <[email protected]>

2015-06-26Do not segv if NULL is passed for CTX in sendfd and receivefd.Werner Koch1-2/+2
* 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]>
2014-08-17Fix possible segv in a call to _assuan_debug.Werner Koch1-1/+1
* src/context.c (assuan_set_error): Do not pass NULL for %s in the trace function. -- This likely fixes GnuPG-bug-id: 1659
