* Use Windows library for cryptographic checksumscng_backendRon Yorston2025-06-099-9/+155
| | | | | | | | | | | | | 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.
* win32: update implementation of select(2)Ron Yorston2025-05-261-2/+5
| | | | | | | | Apply gnulib commit 034af0e401 (select, pselect: Fix test failure on native Windows). * lib/select.c (rpl_select): Fail if nfds is out-of-range. * lib/pselect.c (pselect): Likewise.
* win32: update implementation of strptime(3)Ron Yorston2025-05-261-18/+18
| | | | Changes are mostly cosmetic.
* win32: update inet_pton(3) implementationRon Yorston2025-05-261-0/+1
| | | | | | | | | | | | | | | | | | | Apply musl commit 7e13e5ae (inet_pton: fix uninitialized memory use for IPv4-mapped IPv6 addresses). When a dot is encountered, the loop counter is incremented before exiting the loop, but the corresponding ip array element is left uninitialized, so the subsequent memmove (if "::" was seen) and the loop copying ip to the output buffer will operate on an uninitialized uint16_t. The uninitialized data never directly influences the control flow and is overwritten on successful return by the second half of the parsed IPv4 address. But it's better to fix this to avoid unexpected transformations by a sufficiently smart compiler and reports from UB-detection tools. Adds 16 bytes.
* win32: update glob(3) implementationRon Yorston2025-05-261-1/+1
| | | | | | | | | | | Apply musl commit 79bdacff (glob: fix wrong return code when aborting before any matches). when the result count was zero, glob was ignoring a possible GLOB_ABORTED error code and returning GLOB_NOMATCH. whether this happened could be nondeterministic and dependent on the order of dirent enumeration, in cases where multiple matches were present and only some produced errors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * syslogd: Fix 'OPT_locallog' check regression in 'syslogd_main'Grant Erickson2025-04-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the recent refactoring of 'syslogd_main', a regression was introduced in handling the manual bitwise OR of 'OPT_locallog' as follows: if (ENABLE_FEATURE_REMOTE_LOG && !(opts & OPT_remotelog)) // -R option_mask32 |= OPT_locallog; 'opts' represents the locally-scoped output of 'getopt32' and 'option_mask32' represents the globally-scoped state of the same. Consequently, the above performs a bitwise OR to include 'OPT_locallog' of the globally-scoped option state, which 'opts' will not reflect locally. Manipulating the global, rather than local, state is correct as 'timestamp_and_log_internal' will later need to check 'OPT_locallog'. However, when the aforementioned refactor occurred, the following regressing change was made: - if (!ENABLE_FEATURE_REMOTE_LOG || (option_mask32 & OPT_locallog)) { + if (!ENABLE_FEATURE_REMOTE_LOG || (opts & OPT_locallog)) { breaking the spatially- and temporally-removed check in 'timestamp_and_log_internal'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, udhcpc6 does not meet the requirements for Identity Association in RFC 3315. This is a specific explanation in RFC 3315 protocol: https://datatracker.ietf.org/doc/html/rfc3315#section-10 "The IAID uniquely identifies the IA and must be chosen to be unique among the IAIDs on the client. The IAID is chosen by the client. For any given use of an IA by the client, the IAID for that IA MUST be consistent across restarts of the DHCP client."

These last two changes are useful to deal with hopelessly broken DHCPv6 servers such as the one from the Orange Livebox (one of the main French ISPs) which I'm currently having the displeasure to have to talk to, hence the patch. function old new delta static.send_d6_renew - 126 +126 .rodata 105598 105649 +51 udhcpc6_main 2607 2650 +43 packed_usage 34933 34953 +20 d6_send_kernel_packet_from_client_data_ifindex 266 282 +16 send_d6_renew 174 - -174 ------------------------------------------------------------------------------ (add/remove: 1/1 grow/shrink: 4/0 up/down: 256/-174) Total: 82 bytes Signed-off-by: Laurent Bercot <ska-dietlibc@skarnet.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* | build system: include stack unwind tablesRon Yorston2025-05-186-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9b80b903c7 (build system: stop .eh_frame generation) added compiler flags to prevent unwind tables being included in the binary. BusyBox doesn't normally require such tables and the size of the binary was much reduced. Windows' Control Flow Guard feature needs unwind tables. Without them calls to longjmp(3), widely used in BusyBox, fail. Add a configuration option to control whether or not unwind tables are included. (GitHub issue #495)

* | win32: fake directories in readdir(2)Ron Yorston2025-03-171-5/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The emulation of readdir(2) didn't include the '.' and '..' directories in the root of a logical drive. This resulted in the 'ls' applet (and others) not matching the expected Unix behaviour. Alter the emulation of readdir(2) to include fake '.' and '..' directories if necessary. Adds 88-112 bytes. (GitHub issue #487)
* | win32: enhanced support for SIGPIPEFRP-5579-g5749feb35Ron Yorston2025-02-081-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 68ddd4ec3c (win32: emulate SIGPIPE) allowed broken pipes to be detected so that processes could either return EPIPE or terminate. Later, commit 1b2ee3667 (win32: add fake HUP and QUIT signals) added support for two additional fake signals, thus allowing the 'kill' applet to refer to them by name and the shell to define (though not execute) traps for them. Add PIPE to the list of signals known to 'kill' and the shell, though still without support for calling the trap function. (GitHub issue #482)
* | win32: retry when command needs elevated privilegesRon Yorston2025-02-034-12/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* | make: fix detection of target rule with inline commandRon Yorston2025-01-221-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f9d10b2b6 (make: fix detection of target rules (take 2)) added code to handle the case where a target rule had an inline command with a ';' separator in a macro. This required all macros on the line to be expanded, including those in the inline command. The ';' should first be searched for in the original line (without any macro expansion) and only if that fails should macros be expanded. This matches the behaviour of GNU and Unix V7 make. BSD and Schily make don't handle the case where the ';' is in a macro. (pdpmake GitHub issue 73)
* | make: fix single-suffix inference rule regressionRon Yorston2025-01-212-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | Commit 85bbce87d (make: support GNU/BSD suffixes and inference rules) added code to handle inference rules with arbitrary suffixes. Unfortunately it failed to check for a single-suffix rule in the case where no known suffix was found. Add the necessary code and a test which would have caught the problem. Adds 48 bytes. (pdpmake GitHub issue 72)
* | make: phony targets and double colon rulesRon Yorston2025-01-161-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 770bad1fe (make: disallow inference rules for phony targets) added the GNU/BSD make feature that inference rules aren't used for phony targets. Normally a double-colon rule without associated commands causes an inference rule search. If the target of the double-colon rule was phony no search was carried out and the rule failed. As a result of this perl failed to build (on Linux, I didn't try on Windows). When a double-colon rule has no commands and a phony target the prerequisites should be built and the rule should succeed. Adds 32 bytes. (pdpmake GitHub issue #70)
* | make: minor tweaksRon Yorston2025-01-161-32/+37
| | | | | | | | | | | | | | | | | | | | | | Move the code to remove the suffix from a target into a separate function. There's no need to test for non-NULL 'makefile' in newcmd(). Cosmetic changes. Saves 0-16 bytes.
* | make: support GNU/BSD suffixes and inference rulesRon Yorston2025-01-143-71/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The specification of inference rules in POSIX implies that only suffixes starting with a period and containing no other periods are to be considered. In contrast, both GNU and BSD make allow suffixes to contain an arbitrary number of periods, or none at all. Allow this as an extension. Adds 640-816 bytes. (pdpmake GitHub issue 70)
