* lavf/tls_mbedtls: add workaround for TLSv1.3 vs. verify=0sfan52024-06-18
| | | | | | | | | | As of mbedTLS 3.6.0 TLSv1.3 is enabled by default and certificate verification is now mandatory. Our default configuration does not do verification, so downgrade to 1.2 in these situations to avoid breaking it. ref: https://github.com/Mbed-TLS/mbedtls/issues/7075 Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | | | | | | | Also make the iso_channel_position table consistent with what the AAC decoder uses in avcodec/aac/aacdec_usac.c.

* riscv: probe for Zbb extension at load timeRémi Denis-Courmont2024-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to hysterical raisins, most RISC-V Linux distributions target a RV64GC baseline excluding the Bit-manipulation ISA extensions, most notably: - Zba: address generation extension and - Zbb: basic bit manipulation extension. Most CPUs that would make sense to run FFmpeg on support Zba and Zbb (including the current FATE runner), so it makes sense to optimise for them. In fact a large chunk of existing assembler optimisations relies on Zba and/or Zbb. Since we cannot patch shared library code, the next best thing is to carry a flag initialised at load-time and check it on need basis. This results in 3 instructions overhead on isolated use, e.g.: 1: AUIPC rd, %pcrel_hi(ff_rv_zbb_supported) LBU rd, %pcrel_lo(1b)(rd) BEQZ rd, non_Zbb_fallback_code // Zbb code here The C compiler will typically load the flag ahead of time to reducing latency, and can also keep it around if Zbb is used multiple times in a single optimisation scope. For this to work, the flag symbol must be hidden; otherwise the optimisation degrades with a GOT look-up to support interposition: 1: AUIPC rd, GOT_OFFSET_HI LD rd, GOT_OFFSET_LO(rd) LBU rd, (rd) BEQZ rd, non_Zbb_fallback_code // Zbb code here This patch adds code to provision the flag in libraries using bit manipulation functions from libavutil: byte-swap, bit-weight and counting leading or trailing zeroes.
* lavf/tls_mbedtls: handle session ticket error code as no-opsfan52024-06-11
| | | | | | | | | | When TLSv1.3 and session tickets are enabled mbedtls_ssl_read() will return an error code to inform about a received session ticket. This can simply be handled like EAGAIN instead of errornously aborting the connection. ref: https://github.com/Mbed-TLS/mbedtls/issues/8749 Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavf/tls_mbedtls: fix handling of certification validation failuressfan52024-06-11
| | | | | | | | | | We manually check the verification status after the handshake has completed using mbedtls_ssl_get_verify_result(). However with VERIFY_REQUIRED mbedtls_ssl_handshake() already returns an error, so this code is never reached. Fix that by using VERIFY_OPTIONAL, which performs the verification but does not abort the handshake. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavf/tls_mbedtls: hook up debug message callbacksfan52024-06-11
