- Why? Because code where conditionals lack braces is much harder to read, and prone to indentation confusion.
- How? Just added an extra flag to .clang-format and re-ran clang-format on all the files.
I also moved .clang-format up to the top level of the repo so that it can be applied to the fuzz targets as well.
For our deployment, it is useful if coturn returns a valid HTTP response to an HTTP request. To do this on the same port as STUN/TURN and without enabling the admin site, I have extended `read_client_connection()` to return a canned HTTP response, in response to an HTTP request, rather than immediately closing the connection.
- srandom/random provide stronger randomness characteristics than
srand/rand in some operating systems.
- usage of srand/rand is not very consistent in coturn.
There is room for more refactoring and use apputils helper functions in
ns_turn_msg.c too but i'm not sure that dependency from "client" module
to "apps" module is a good idea yet.
Thx @0xdea

Fixes https://github.com/coturn/coturn/issues/1239
https to web ui freeze in browser if no_tls option used, because no tls
stuff initialized.
This PR add warning about this and comment aboute this in default config
There are two different API's in OpenSSL for configuring TLS ciphers,
one for TLS 1.2 and below, and another for TLS 1.3. coturn only calls
the TLS 1.2 API when handling the `--cipher-list` configuration option,
which means that it's not possible to use non-default ciphersuites with
TLS 1.3 connections.
This PR calls appropriate OpenSSL API to allow TLS 1.3 ciphersuites to be configured.
coturn running inside a docker container runs as PID 1, however PID 1
has special signal handling semantics (see the note at the bottom of the
section
[here](https://docs.docker.com/engine/reference/run/#foreground)).
coturn relies on the default behaviour of SIGTERM to terminate the
process, however as no signal handler is explicitly installed, it
doesn't respond to SIGTERM when running inside a container. This PR
fixes this problem by installing explicit signal handlers for SIGINT and
SIGTERM, which trigger the same termination mechanism as the admin
interface "halt" command.
This is a port of wireapp#6 for upstream.
This PR fixes some errata from #996 and #989:
- Some DTLS code was left over in the common path for allocating and
initialising `SSL_CTX`'s, and the DTLS-specific configuration code was
erroneously operating on the TLS context instead of the DTLS context.
- In both the TLS and DTLS codepaths, the previous refactoring inverted
the logic for the `--no-tlsv1`/`--no-tlsv1_1`/etc command line options,
so that these options would instead *enable* the respective (D)TLS
versions, instead of disabling this. This would mean that by default
coturn would only support TLS 1.3 and DTLS 1.2, and no earlier versions.
I've also regenerated the manual pages (with the `make-man.sh` script)
to match the documentation in the README files.
Reformatting and removing some duplications:
- Some lines have WARNING WARNING: cleaned up.
- Lines printed using perror: only LOG_ mechanism should be used.
- Printing IO mechanism (epoll for example) for each thread: selected
mechanism logged once
- Duplicate lines (perror and also LOG): duplication removed
- Duplicates: clean up (because calling function multiple times -
configuration load)
I would like to get feedback on this and see if people is confortable
with these clang rules.
Right now is using the "llvm" style increasing the line length from 80
to 120 given that coturn is using long lines often.

`TURN_NO_HIREDIS` is defined when hiredis library is not present and any
redis functionality must be disabled
While all above is correct, it does not require ifdef-ing out all
related code.
For example, redis related fields in `turn_params` do not need to be
compiled out. Same for certain function parameters.
This PR reduces amount of places in code where `TURN_NO_HIREDIS` is used
to make code simpler by moving as much usage of this define into
dbd_redis.h/c files and compiling them unconditionally.
- Always compile/link `dbd_redis.c`
- Move many `TURN_NO_HIREDIS` decisions into `dbd_redis.c`
- Delete empty function redis_async_init
`TURN_NO_PROMETHEUS` is defined when prometheus libraries are not
present and any prometheus functionality must be disabled
While all above is correct, it does not require ifdef-ing out all
related code.
For example, prometheus related fields in turn_params do not need to be
compiled out. Same for certain function parameters.
This PR reduces amount of places in code where `TURN_NO_PROMETHEUS` is
used to make code simpler by moving as much usage of this define into
prom_server.h/c files and compiling them unconditionally.
- Always compile/link prom_server.c
- Move many TURN_NO_PROMETHEUS decisions into prom_server.c
The following changes have been made:
1. Replace deprecated functions with new standard functions
2. Add corresponding MSVC functions for non-standard functions
3. Remove warnings about unsafe functions
4. CMAKE: modify find pack Libevent and openssl
5. Modify include files
6. Use pthread4W
7. Modify socket in windows
8. Add CI - github action
8.1. msvc
8.2. mingw
10. The database:
9.1. sqlite, pgsql, hiredis, mongo is test compiled.
9.2. mysql, isnot test compiled.
11. The applications、server can be compiled and run successfully!
12. Add vcpkg manifest mode in cmake.
Rewriting openssl initialization code (threading support to make it
cleaner
- Regroup functions so that there is one ifdef (for old code and new
code)
- Modern openssl (>1.0.2) does not need any synchornization routines so
they are empty
- Old openssl (<=1.0.2) now require `OPENSSL_THREADS` which allows
running multiple threads in turnserver. Not having turnserver
multi-threaded is a huge waste. `OPENSSL_THREADS` is now a requirement.
Test Plan:
- CI builds pass for openssl versions 1.0.2, 1.1.1, 3.0, including tests
Store sanitized version of DB connection string with password masked
(replace all chars with * which exposes its length)
Use sanitized version when logging connection string
Fixes#1017 and #272
Similar to #989, use a single SSL context for all versions of DTLS
protocol
- Add support for modern API (protocol version independent APIs)
- Add DTLS test to the CI test
- Removing calls to `SSL_CTX_set_read_ahead` in DTLS context (does
nothing as DTLS is datagram protocol - we always get the whole datagram
so this call has no impact)
Fixes#924
STRCPY macro makes pointer comparison which creates a warning
In those places, replace the macro with `strncpy` with careful review of
destination buffer size
With this change I do not get compiler warnings at all
openssl allows multiple TLS version support through a single SSL_CTX
object.
This PR replaces 4 per-version SSL_CTX objects with a single object
(DTLS is not yet changed).
SSL context initialization code for openssl with modern API (>=1.1.0)
uses `TLS_server_method` and `SSL_CTX_set_min_proto_version` instead of
enabling specific TLS version. Byproduct of this is TLSv1_3 support when
used with openssl-1.1.1 and above
TLS 1.2 and TLS 1.3 cannot be disabled (as before)
Test plan:
- run_tests.sh script now runs turnserver with SSL certificate (which
enables TLS support)
- run_tests.sh now has one more basic test that uses TLS protocol

Replace all instances of `bzero` with memset by find-replace-edit.
This is straightforward replacement which is suboptimal in a few cases
(for example we could use calloc instead of malloc+memset(0))
Inspired by #855
Multiple DTLS listener servers are created, and server->dtls_ctx is
the same object shared between them.
Set these callbacks once, and logically this is at the point where the
SSL context is created.
