+Modified from upstream commit:
+https://github.com/ankitects/anki/commit/ccd715013609133c55e83924734efa78abc03326
+Fixes mpv argument syntax (support for old syntax removed in mpv 0.31):
+https://anki.tenderapp.com/discussions/ankidesktop/38186-mpvprocesserror-unable-to-start-process
+Necessary because we are currently unable to upgrade anki to the
+latest version in guix (NPM dependencies currently unpackaged).

+Subject: [PATCH] tcp_emu: fix unsafe snprintf() usages
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Various calls to snprintf() assume that snprintf() returns "only" the
+number of bytes written (excluding terminating NUL).
+
+https://pubs.opengroup.org/onlinepubs/9699919799/functions/snprintf.html#tag_16_159_04
+
+"Upon successful completion, the snprintf() function shall return the
+number of bytes that would be written to s had n been sufficiently
+large excluding the terminating null byte."
+
+Before patch ce131029, if there isn't enough room in "m_data" for the
+"DCC ..." message, we overflow "m_data".
+
+After the patch, if there isn't enough room for the same, we don't
+overflow "m_data", but we set "m_len" out-of-bounds. The next time an
+access is bounded by "m_len", we'll have a buffer overflow then.
+
+Use slirp_fmt*() to fix potential OOB memory access.

+Subject: [PATCH] util: add slirp_fmt() helpers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Various calls to snprintf() in libslirp assume that snprintf() returns
+"only" the number of bytes written (excluding terminating NUL).
+
+https://pubs.opengroup.org/onlinepubs/9699919799/functions/snprintf.html#tag_16_159_04
+
+"Upon successful completion, the snprintf() function shall return the
+number of bytes that would be written to s had n been sufficiently
+large excluding the terminating null byte."
+
+Introduce slirp_fmt() that handles several pathological cases the
+way libslirp usually expect:
+
+- treat error as fatal (instead of silently returning -1)
+
+- fmt0() will always \0 end
+
+- return the number of bytes actually written (instead of what would
+have been written, which would usually result in OOB later), including
+the ending \0 for fmt0()
+
+- warn if truncation happened (instead of ignoring)
+
+Other less common cases can still be handled with strcpy/snprintf() etc.
