annotate src/os/unix/ngx_files.c @ 7687:69345a26ba69 quic
Split transport and crypto parts into separate files.
New files:
src/event/ngx_event_quic_protection.h
src/event/ngx_event_quic_protection.c
The protection.h header provides interface to the crypto part of the QUIC:
2 functions to initialize corresponding secrets:
ngx_quic_set_initial_secret()
ngx_quic_set_encryption_secret()
and 2 functions to deal with packet processing:
ngx_quic_encrypt()
ngx_quic_decrypt()
Also, structures representing secrets are defined there.
All functions require SSL connection and a pool, only crypto operations
inside, no access to nginx connections or events.
Currently pool->log is used for the logging (instead of original c->log).
