* | 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.

| * libbb: Prevent clang from reading the G pointer before it is assignedBin Meng2025-07-011-19/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

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.

* | ash: optimise running of scripts (2)Ron Yorston2024-09-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 4b7b4a960 (ash: optimise running of scripts) avoided creation of a process when running a script. There's another case where we can do the same: if the script is being run from a FS_SHELLEXEC shell. - Check the necessary conditions for this to happen. - Allocate two extra slots in the argv array for FS_SHELLEXEC. - Set the index of the script file in the argv array. Without this the test 'pidof this' failed because the command name hadn't been correctly set. Adds 80-96 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BusyBox shell detects certain cases where forking a command is unnecessary (last command in a script or subshell, for example) and calls execve(2) instead. This doesn't help in the Windows port because execve(2) is implemented by creating a process. There is one case where it is possible to apply this optimisation: if the command is a script and the script interpreter is an applet. - Have evalcommand() pass a flag to indicate this situation to shellexec(). Also, allocate two spare elements before the start of the argv array. - If the flag is TRUE shellexec() passes the shell's PATH variable down to tryexec() so it can perform a test for applet override. - If tryexec() finds that all the necessary conditions apply it can run a script by directly invoking the interpreter's main(). Adds 192-224 bytes.
* | win32: code shrinkRon Yorston2024-08-161-17/+17
| | | | | | | | | | Add the FAST_FUNC qualifier to several Windows-specific functions. This has no effect in 64-bit builds but saves 336 bytes for 32-bit.
* | win32: use 64-bit time on 32-bit platformsRon Yorston2024-08-142-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To avoid problems with dates in 2038 and beyond use 64-bit time values on 32-bit platforms. - Mostly this just requires a few preprocessor macros to choose the appropriate functions, structs and typedefs. - We have our own implementations of nanosleep(), clock_gettime() and clock_settime(). Omit the Windows include file that declares them. - Apply the hack for struct timeval in the 'ts' applet on 32-bit. Adds 1624 bytes on 32-bit, none on 64-bit. (GitHub issue #446)
* | su: detect inability to raise privilegeRon Yorston2024-08-031-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | When privilege has been dropped by the 'drop' applet, the 'su' applet is unable to raise it again because ShellExecuteEx() thinks it unnecessary. Detect this situation, report an error and return exit code 2. Costs 72-112 bytes. (GitHub issue #437)
