0-return from quic_record_append is an error. `quic_record_complete(qr) || len == 0` is not an error condition. We should return as normal on success.
The issue is that passing in buffers with length 1 then 3 causes `qr_length` (in `quic_record_make`) to return 0. Then when `quic_record_append` gets called the `len` gets consumed by the first `if` and `len == 0` is true. This causes the error return which is not correct behaviour.
Reported in https://github.com/wolfSSL/wolfssl/issues/8156. Reproducing is a bit tricky. I couldn't get the docker to work.
First setup ngtcp2 as described in https://github.com/ngtcp2/ngtcp2/pkgs/container/ngtcp2-interop. The Relevant steps are (I tested with master/main branches of all libs):
```
$ git clone --depth 1 -b v5.7.4-stable https://github.com/wolfSSL/wolfssl
$ cd wolfssl
$ autoreconf -i
$ # For wolfSSL < v5.6.6, append --enable-quic.
$ ./configure --prefix=$PWD/build \
--enable-all --enable-aesni --enable-harden --enable-keylog-export \
--disable-ech
$ make -j$(nproc)
$ make install
$ cd ..
$ git clone --recursive https://github.com/ngtcp2/nghttp3
$ cd nghttp3
$ autoreconf -i
$ ./configure --prefix=$PWD/build --enable-lib-only
$ make -j$(nproc) check
$ make install
$ cd ..
$ git clone --recursive https://github.com/ngtcp2/ngtcp2
$ cd ngtcp2
$ autoreconf -i
$ # For Mac users who have installed libev with MacPorts, append
$ # LIBEV_CFLAGS="-I/opt/local/include" LIBEV_LIBS="-L/opt/local/lib -lev"
$ ./configure PKG_CONFIG_PATH=$PWD/../wolfssl/build/lib/pkgconfig:$PWD/../nghttp3/build/lib/pkgconfig \
--with-wolfssl
$ make -j$(nproc) check
```
Download and unzip https://github.com/user-attachments/files/17621329/failing.pcap.zip
From the ngtcp2 dir:
```
./examples/wsslserver 127.0.0.1 44433 /path/to/wolfssl/certs/server-key.pem /path/to/wolfssl/certs/server-cert.pem
```
Then run the following python script (`failing.pcap` has to be available in the running dir) (probably needs to be run as `sudo`):
```
from scapy.utils import rdpcap, PcapNgReader
from scapy.all import *
reader = PcapNgReader("failing.pcap")
for i in reader:
p = i[IP]
p.dport = 44433
p.dst = "127.0.0.1"
p[UDP].chksum=0
p.display()
send(p)
```
Then observe the log line:
```
I00000000 0xa48accb7b49ec1556ac7111c64d3a4572a81 frm tx 625216795 Initial CONNECTION_CLOSE(0x1c) error_code=CRYPTO_ERROR(0x100) frame_type=0 reason_len=0 reason=[]
```
You can also use `gdb` and place a break inside the following section in `wolfssl/src/quic.c`.
```
if (quic_record_complete(qr) || len == 0) {
return 0;
}
```
This reverts commit bc12dad041.
This commit broke builds that combine QUIC and PQ -- known failures are pq-all-valgrind-unittest, pq-hybrid-all-rpk, pq-hybrid-all-rpk-valgrind-unittest, quantum-safe-wolfssl-all-gcc-latest, quantum-safe-wolfssl-all-g++-latest, quantum-safe-wolfssl-all-fortify-source-asm, quantum-safe-wolfssl-all-fortify-source-asm-noasm, and quantum-safe-wolfssl-all-intelasm-sp-asm-valgrind.
Note that the unit.test asserts added by this commit fail both before and after reversion.
several fixes for defects reported by cppcheck:
wolfcrypt/src/ecc.c: fix for cppcheck oppositeInnerCondition from cppcheck-2.16.0 in _ecc_make_key_ex(), and fixes for related unhandled errors discovered by manual inspection;
wolfcrypt/test/test.c: fix XREALLOC call in memcb_test() to resolve cppcheck-detected memleak.
