gpgme/src/data.c, branch gpgme-1.16.0

core: New data flags "io-buffer-size" and "sensitive".

2021-06-14T17:51:28Z

* src/data.c (_gpgme_data_release): Free buffers. (gpgme_data_seek): Adjust from renamed fields. (gpgme_data_set_flag): Implement new flags. (_gpgme_data_inbound_handler): Allow the use of a malloced buffer. (_gpgme_data_outbound_handler): Ditto. * src/data.h (BUFFER_SIZE): Move out of the struct definition. (struct gpgme_data): Remove pending filed and introduce inbound and outbound fields. * src/conversion.c (_gpgme_wipememory): New. Taken from GnuPG. * src/cJSON.c (wipememory): Use this here too. * tests/run-decrypt.c (main): Add options "--large-buffers" and "--sensitive". -- GnuPG-bug-id: 5478 Signed-off-by: Werner Koch

core: Also detect AuthEnvelopedData (AEAD for CMS)

* src/data-identify.c (basic_detection): Add OID. Signed-off-by: Werner Koch

core: Improve the debug messages even more.

2019-06-05T13:54:55Z

* src/debug.c (_gpgme_debug): Add arg LINE. Chnage all callers. (_gpgme_debug_begin): Remove. * src/debug.h (TRACE_SEQ): Use the LINE arg of _gpgme_debug. -- This includes chnages to always print fds in decimal as weel as tweaking the TARCE_SEQ function to make use of the new machinery. The standard 'tag' can now always be NULL and no tag information will be printed. Signed-off-by: Werner Koch

core: Fix format string errors in trace macros

core: Simplify the trace maros by using variadics.

2018-11-16T15:25:49Z

* src/debug.h (TRACE_BEG, TRACE_LOG, TRACE_SUC): Use variadic macros and remove the TRACE_BEG1 et al. Change all users to always pass a format string. (TRACE): Ditto. * src/debug.c (_gpgme_debugf): New. * configure.ac : Add -Wno-format-zero-length. -- This makes it easier for use to enable format checks. The zero-length format is required to allow for an empty format due to the comman problematic of __VA_ARGS__. Signed-off-by: Werner Koch

core: Blank out the plaintext after decryption failure.

2018-07-19T15:39:09Z

* src/data.h (data_prop_t): New enum. (struct gpgme_data): Add field propidx. * src/data.c (property_t): New. (property_table, property_table_size, property_table_lock): New. (insert_into_property_table): New. (remove_from_property_table): New. (_gpgme_data_get_dserial): New. (_gpgme_data_set_prop): New. (_gpgme_data_get_prop): New. (_gpgme_data_new): Connect new object to property_table. (_gpgme_data_release): Remove from property_table. (gpgme_data_read): With DATA_PROP_BLANKOUT set don't fill the buffer. * src/data-mem.c (gpgme_data_release_and_get_mem): Likewise. * src/decrypt.c (struct op_data): Add field plaintext_dserial. (_gpgme_op_decrypt_init_result): Add arg plaintext and init new field. (_gpgme_decrypt_status_handler): Set DATA_PROP_BLANKOUT on decryption failure. (_gpgme_decrypt_start): Pass PLAIN to the init function. * src/decrypt-verify.c (decrypt_verify_start): Ditto. * configure.ac: Check for stdint.h and bail out if uint64_t is not available. -- This is a best effort feature to not output plaintext after a decryption failure (e.g. due to no or broken authenticated encryption). It always work when using a memory object and reading it after the decryption but it can't work reliable when the user is reading from the data object while the decryption process is still running. This is quite a large change because the data objects and the context objects are allowed to be owned by different threads. Thus a synchronization is needed and we do this with a global table of all data objects to which the context objects can do soft-linking via a unique data object serial number.

core: Also check for a failed selftest in gpgm_data_new.

2017-12-04T11:08:31Z

* src/data.c (_gpgme_data_new): Check for failed selftest. * tests/run-support.h (make_filename): Print a message on mallooc failure. (init_gpgme_basic): New. * tests/run-identify.c (main): Call init_gpgme_basic becuase we do not need to setup a protocol. * tests/t-data.c: Define PGM and include run-support.h. (make_filename): Remove. (main): Call init_gpgme_basic. -- Note: This patch may break applications which used gpgme_data but no gpgme_new without having called the required gpgme_check_version. GPGME can be used without a protocol for example to work with the data object abstraction. Thus a call to gpgme_data_new also needs to check the result of the core selftests - including on whether gpgme_check_version has been called. Signed-off-by: Werner Koch
