address if you want to avoid data loss.
|
||||
Thanks to Chunmei Xu for reporting this issue and proving the patch.
|
||||
|
||||
Socats DTLS implementation has been reworked and appears to work now
|
||||
reasonably over UDP.
|
||||
New addresses: OPENSSL-DTLS-SERVER (DTLS-L),
|
||||
OPENSSL-DTLS-CLIENT (DTLS)
|
||||
Tests: OPENSSL_DTLS_CLIENT OPENSSL_DTLS_SERVER
|
||||
OPENSSL_METHOD_DTLS1 OPENSSL_METHOD_DTLS1.2
|
||||
Thanks to Brandon Carpenter, Qing Wan, and Pavel Nakonechnyi for
|
||||
sending patches.
|
||||
|
||||
Porting:
|
||||
In gcc version 10 the default changed from -fcommon to -fno-common.
|
||||
Consequently, linking filan and procan failed with error
