Status for rust-secp256k1-sys/0.14.1+dfsg-4

Patch Description Author Forwarded Bugs Origin Last update
build-system-lib.patch Build against the system libsecp256k1 instead of the bundled one The crate bundles the full libsecp256k1 C source under depend/ and compiles
it at build time with the cc crate. Debian instead uses the packaged
libsecp256k1: drop the cc build-dependency, link against the system library
and enable the rust_secp_no_symbol_renaming cfg so the FFI refers to the
unprefixed secp256k1_* symbols exported by the system library.		 Ying-Chun Liu (PaulLiu) <paulliu@debian.org> not-needed 2026-10-22
fix-verify-types-on-non-x86.patch Make verify_types pass on targets where C char is unsigned The `verify_types` test asserted that the crate's `types::c_char` (hardcoded
to `i8`) has the same TypeId as `std::os::raw::c_char`. On aarch64 and
several other targets C's `char` type is unsigned, so `std::os::raw::c_char`
is `u8` there and the assertion failed (FTBFS of the autopkgtest on arm64).
The crate itself documents that `types::c_char` "might not match C's c_char
exactly" and is only used in a way that works either way; only size and
alignment matter for the FFI bindings, so relax the assertion accordingly.		 Ying-Chun Liu (PaulLiu) <paulliu@debian.org> invalid vendor 2026-10-25
0002-provide-lax-der-parser.patch Build the vendored lax DER parser against the system libsecp256k1 The system libsecp256k1 does not compile contrib/lax_der_parsing.c into the
shared library (it is only used by the upstream test suite), so the Debian
libsecp256k1 does not export `ecdsa_signature_parse_der_lax`. The sys crate
therefore loses that symbol when linked against the system library, breaking
`secp256k1::ecdsa::Signature::from_der_lax()` in the high-level crate.
.
Re-add the cc build-dependency and compile a vendored copy of
lax_der_parsing.c (with its header) next to the system libsecp256k1 so that
the symbol remains available to consumers. This is a Debian-specific
integration because upstream builds the bundled libsecp256k1 itself.		 Ying-Chun Liu (PaulLiu) <paulliu@debian.org> not-needed vendor 2026-11-01
