2021-02-01idevice: Allow partial reads in idevice_connection_receive_timeout() and ↵Gravatar Nikias Bassen1-6/+9
handle timeouts more adequate idevice_connection_receive_timeout(), when in SSL mode, was assuming it should always try to read the exact amount of data specified in `len` parameter. While this works with most protocols that have length fields or fixed sized headers/packets, some others (e.g. debugserver) break because it will request a read but doesn't know the size that is expected to be returned beforehand. This commit will handle timeouts better and return the number of bytes that were read in such cases (instead of returning 0 bytes read + error). Note that in the event of a timeout, IDEVICE_E_TIMEOUT will be returned even though actual data might have been read. The number of bytes read will be returned in recv_bytes.

2020-06-06idevice: Revert not copying scope id for IPv6 addresses from usbmuxd againGravatar Martin Szulecki1-2/+2
This should still catch the more common case when using usbmuxd on the same host. Not copying the scope id in that case actually removes vital routing information.
2020-06-06idevice: Slightly improve connectivity logic and fix IPv6 for network devicesGravatar Martin Szulecki1-6/+8
This change removes copying the scope id for IPv6 connections which caused problems if the usbmux connection data is used on different hosts or context.

2019-07-19OpenSSL: Use SSL_pending() to determine if we want a select() before SSL_read()Gravatar Nikias Bassen1-11/+16
In order to obey the timeout in idevice_connection_receive_timeout(), we are using select() via socket_check_fd(). However, the SSL bio might have buffered more bytes than actually requested upon a call to SSL_read(), so in the next call to idevice_connection_receive_timeout() a select() would not find the fd being ready to read, and make it fail with an error, after the specified timeout is reached. With the help of SSL_pending() we can now skip calling select() so that SSL_read() will directly be called again.
2019-06-22Make sure to not use deprecated API when compiling with OpenSSL >= 1.1Gravatar Rosen Penev1-1/+7
There are several missing headers as well as deprecated functions for which compatibility was added as needed.

older device On newer iOS version, ValidatePair is not mandatory to gain trusted host status. Starting with iOS 11, the ValidatePair request has been removed from lockdownd and will throw an error. This commit adds a version check so that ValidatePair is only called on devices prior iOS 7.

2017-04-26 #ifdef out code which is a no-op with OpenSSL 1.1.0Gravatar Christophe Fergeau1-0/+6
CRYPTO_set_id_callback CRYPTO_set_locking_callback EVP_cleanup CRYPTO_cleanup_all_ex_data SSL_COMP_free_compression_methods are all no-ops with OpenSSL 1.1.0, so we can #ifdef out the corresponding code. This cleans up some warnings about id_function/locking_function being defined but unused (as the calls to CRYPTO_set_id_callback and CRYPTO_set_locking_callback disappear at preprocessing time).

2017-04-26Don't use ERR_remove_thread_state() with OpenSSL 1.1.0Gravatar Christophe Fergeau1-14/+16
It's deprecated and causes compile-time warnings. We don't want to fallback to ERR_remove_state() either as it's similarly deprecated. This commit adds a helper functions to hide the #ifdef mess between the various openssl versions. Signed-off-by: Christophe Fergeau <cfergeau@redhat.com>
2017-04-26Avoid double free with OpenSSL 1.1.0Gravatar Christophe Fergeau1-1/+9
Since commit OpenSSL_1_1_0-pre3~178 https://github.com/openssl/openssl/commit/b184e3ef73200cb3b7914a603b43a5b8a074c85f OpenSSL automatically cleans up some of its internal data when the program exits. This conflicts with some similar clean up libimobiledevice attempts to do, which causes a double-free. SSL_COMP_free_compression_methods() was available in OpenSSL 1.0.2, and is still there in 1.1.0 as a no-op, so we can use that to free the compression methods.

2016-08-02idevice: Update GnuTLS code to support iOS 10Gravatar Jay Freeman (saurik)1-1/+1
As of iOS 10 beta 4, the GnuTLS implementation idevice_connection_enable_ssl needs to be updated to support TLS. Using +VERS-TLS-ALL did not work on some of the devices I tested and I wasn't sure how to fix it, but +VERS-TLS1.0 is working on every device I've tested: iOS 9.0.2, 10.0b4, 8.1.1, 6.0, and 3.0.
