* win32: avoid failure when localtime() argument is out of rangeRon Yorston2025-11-261-1/+4
| | | | | | | | | | | | | | | | | | | | The implementation of localtime(3) in the Microsoft Windows runtime only accepts arguments between the Unix epoch (1970) and either 2038 or 3000 for 32-bit or 64-bit systems respectively. For values outside those limits it returns a NULL pointer. Unfortunately, upstream BusyBox hardly ever bothers to check the return value. Thus, when a call to stat(2) returned an all-zero FILETIME for a file, the 'stat' applet failed. An all-zero FILETIME represents a date in 1600, which is clearly before the Unix epoch. Add a wrapper to localtime(3) which detects an out-of-range value and returns a valid 'struct tm' for the Unix epoch. This is easier than adding checks on the return value of every call to localtime(3). Adds 32-48 bytes. (GitHub issue #548)

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 6481bb22b (win32: use 64-bit time on 32-bit platforms) fails to build with mingw32-gcc prior to mingw-w64 10.0.0. Don't used 64-bit time for such builds. mingw-w64 7.0.0 and below don't have some definitions required for native TLS support. This is enabled by default in the 64-bit Unicode build. Add the definitions required for the default build. TLS 1.3 support needs more but isn't enabled by default. (GitHub issue #527)
* | ash: eval: Add vfork supportRon Yorston2025-09-071-0/+2

* | 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().

| * 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>
* | win32: retry when command needs elevated privilegesRon Yorston2025-02-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some installer programs have an entry in their manifest to indicate that they need elevated privileges. The shell in busybox-w32 was unable to run such programs. When a program fails to run with ERROR_ELEVATION_REQUIRED, try again using ShellExecuteEx() with the 'runas' verb to give it elevated privileges. Adds 272-288 bytes. (GitHub issue #481)
* | ash: match behaviour of cmd.exe in cd builtinRon Yorston2024-11-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Windows API strips trailing dots and spaces from the last component of a path. cmd.exe handles this quirk when changing directory by adjusting its idea of the current directory to match reality. The shell in busybox-w32 didn't do this, leading to some confusion. Fix the shell's cd builtin so it works more like cmd.exe. Adds 64-80 bytes. (GitHub issue #478)
* | 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.
