The extra copy of sha256 code need to be removed. The yescrypt code in libbb/yescrypt/* is adapted from libxcrypt-4.4.38 with minimal edits, hopefully making it easier to track backports by resetting the tree to this commit, then comparing changes in upstream libxcrypt to the tree. function old new delta blockmix_xor_save - 7050 +7050 static.blockmix_xor - 6475 +6475 blockmix - 3390 +3390 SHA256_Transform - 3083 +3083 yescrypt_kdf_body - 1724 +1724 PBKDF2_SHA256 - 1003 +1003 smix1 - 960 +960 yescrypt_r - 890 +890 salsa20 - 804 +804 smix - 790 +790 smix2 - 659 +659 blockmix_salsa8_xor - 601 +601 yescrypt_kdf - 479 +479 blockmix_salsa8 - 415 +415 Krnd - 256 +256 _HMAC_SHA256_Init - 213 +213 _SHA256_Update - 198 +198 _SHA256_Final - 195 +195 decode64_uint32 - 166 +166 encode64 - 153 +153 decode64 - 136 +136 libcperciva_HMAC_SHA256_Buf - 132 +132 SHA256_Pad_Almost - 131 +131 salsa20_simd_unshuffle - 101 +101 salsa20_simd_shuffle - 101 +101 yes_crypt - 90 +90 libcperciva_SHA256_Buf - 86 +86 crypt_make_rand64encoded - 85 +85 static.atoi64_partial - 77 +77 alloc_region - 72 +72 ascii64 - 65 +65 PAD - 64 +64 _HMAC_SHA256_Final - 55 +55 static.cpu_to_be32_vect - 51 +51 free_region - 47 +47 libcperciva_SHA256_Init - 37 +37 yescrypt_init_local - 34 +34 crypt_make_pw_salt 92 125 +33 initial_state - 32 +32 .rodata 105771 105803 +32 atoi64 - 25 +25 explicit_bzero - 22 +22 pw_encrypt 920 941 +21 yescrypt_free_local - 9 +9 crypt_make_salt 85 - -85 ------------------------------------------------------------------------------ (add/remove: 43/1 grow/shrink: 3/0 up/down: 31042/-85) Total: 30957 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* | win32: retry when command needs elevated privilegesRon Yorston2025-02-031-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* | su: note that test mode implies -W in usage messageRon Yorston2024-08-081-1/+1
| | | | | | | | | | | | Saves 8-16 bytes (GitHub issue #438)
* | su: add test modeRon Yorston2024-08-071-19/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Testing some uses of 'su' can be challenging because any errors appear in the new console window which may close as a result. Add the '-t' option to enable test mode. This starts a new shell using ShellExecuteEx(), but without elevated privileges and a new console. All other options and arguments are handled much as before, though some differences in behaviour are to be expected due to the lack of elevated privilege. Adds 80-96 bytes. (GitHub issue #438)
* | su: use correct option when cmd.exe is used as shellRon Yorston2024-08-051-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | Most Unix shells (and PowerShell) use the '-c' option to specify commands to execute. cmd.exe uses '/c' instead. Detect when cmd.exe is the 'shell' being used with 'su -s' and adjust the command option to suit. Adds 48-56 bytes. (GitHub issue #438)
* | su: allow an alternative shell to be selectedRon Yorston2024-08-041-19/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the '-s' option to allow an alternative shell to be given. No PATH search is performed for the shell, so an absolute or relative path to a suitable executable must be provided. Certain features are only available when the built-in shell is used: - The '-N' option, which allows the console window to remain open when the shell exits. - The fix which allows the current directory to be retained despite the efforts of ShellExecute() to change it. - The friendly message in the console title. Adds 128 bytes. (GitHub issue #438)
* | su: detect inability to raise privilegeRon Yorston2024-08-031-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | 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)
* | su: free all allocated memoryRon Yorston2024-03-081-14/+18
| | | | | | | | | | | | Ensure memory is freed even on early exit. Saves 0-16 bytes.
* | su: handle restricted disk driversRon Yorston2024-03-071-6/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain tools which allow disk image files and RAM disks to be mounted were found to lack a feature used to implement realpath(3). This resulted in a segfault in the 'su' applet when it was run in such a virtual filesystem. 'su' uses realpath(3) to canonicalise the current directory. This is only really required to handle network shares mapped to a drive letter. (GitHub issue #148) - If the call to realpath(3) fails for some reason fall back to using the current directory determined by calling getcwd(3). - If getcwd(3) fails simply don't pass any directory to the shell being started by 'su'. Also, ensure all allocated memory is freed, if required. (GitHub issue #389) Adds 16-32 bytes.
* | win32: convert exit codesRon Yorston2023-09-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add two utility functions to convert Windows process exit codes. - exit_code_to_wait_status() converts to a POSIX wait status. This is used in ash and the implementations of system(3) and mingw_wait3(). - exit_code_to_posix() converts to a POSIX exit code. (Not that POSIX has much to say about them.) As a result it's possible for more applets to report when child processes are killed as if by a signal. 'time', 'drop' and 'su -W', for example. Adds 64-80 bytes.

* | su: add option to keep console open on shell exitRon Yorston2023-05-021-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The '-N' option keeps the console window open after the elevated shell exits. Previously this was achieved by passing the '-s' option along with '-c'. Recent changes allow scripts to be run without using '-c' so a new mechanism is required. su passes the '-N' flag to the shell. This causes the shell to issue a prompt and wait for user input when it exits. Costs 200-204 bytes.
* | su: add option to wait for shell exit codeRon Yorston2023-05-021-3/+27
| | | | | | | | | | | | | | The '-W' option causes su to wait for the elevated shell to terminate and returns its exit code. Costs 144 bytes.
* | su: pass additional arguments to shRon Yorston2023-04-261-9/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The real su allows a command file to be run, with arguments given on the command line. Similarly it allows the script run with '-c' to take arguments. In fact, any arguments can be passed to sh. Permit the same in the Windows implementation. For compatibility this requires a user name to be specified, even though we only support elevation. The user name must be 'root'. Also, ensure the '-c' command is properly quoted. Adds 144-152 bytes.
