Thanks for catching this. I have no idea how that got in there and it makes no sense whatsoever. This patch removes the if conditional.

* | Post-merge fixesRon Yorston2025-08-121-2/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream has moved some functions from networking/tls.c to a new file, libbb/hash_hmac.c. The merge didn't adjust this code to allow it to work with the native Windows checksum API. This only matters if FEATURE_USE_CNG_API is enabled and CONFIG_FEATURE_TLS_SCHANNEL isn't. In that case the wget applet fails to handle https. None of the default configurations has this combination, but it should work. Make it so. The Windows code doesn't implement hmac_block(), as that's only used for password encryption which isn't currently supported. The variadic function hmac_peek_hash() isn't declared FAST_FUNC, as that causes clang to issue many warnings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was observed that getty crashes on RISC-V 64-bit target, with the busybox binary compiled by clang/LLVM 17 with -O2. Not only getty, but also some other applets like syslogd/vi are broken too. Commit 5156b245 ("Make const ptr assign as function call in clang") introduced XZALLOC_CONST_PTR() to defeat the compiler optimization, however it only fixed a small number of broken places when compiling busybox with clang/LLVM. A large number of places remain broken. This commit treats ASSIGN_CONST_PTR() the same way as XZALLOC_CONST_PTR().

* | Use Windows library for cryptographic checksumscng_backendRon Yorston2025-06-091-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a new feature to libbb, FEATURE_USE_CNG_API, which enables the use of the Cryptography API: Next Generation library to calculate checksums. It is disabled by default except in the mingw64u default config, as the API requires Windows 10+ to function. Usage of this API provides a size benefit and delegates hardware optimizations to the operating system cryptography library. Based on GitHub PR #498 by rfl890. Saves 4064 bytes in the mingw64u case.

| * libbb/archival: make setup_unzip_on_fd() return bytes read if not compressedDenys Vlasenko2025-04-201-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | setup_unzip_on_fd() does not return the transformer structure, so the user does not know how much to seek back (or alternatively what the signature was) when compressor signature is not detected. Currently not needed (the only user is tar which dies anyway). However, rpm2cpio may need this if we extend it to extract the internal .cpio even if cpio's compressions algo is not known. function old new delta setup_unzip_on_fd 53 59 +6 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* | test: code shrink supplementary groupsRon Yorston2024-10-091-0/+4
| | | | | | | | | | | | | | | | Since we don't use is_in_supplementary_groups() there's no need for the cached_groupinfo structure to include the members required for its support or for them to be initialised. Saves 32 bytes.

* | libbb: code shrink supplementary group testRon Yorston2024-10-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Recent upstream changes to file permission tests added a function to check and cache values in the supplementary group list. The implementation of getgroups() in the Windows port adds no useful information beyond what can be obtained by checking the current effective gid, which all callers of the new function already do. The function can be replaced with a simple 'FALSE'. Saves 232-288 bytes.
