* tar: fix verbose output with extract-to-stdoutThorsten B2026-08-101-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Combining the verbose (-v) and extract-to-stdout (-O) options caused verbose output and extracted file data to be interleaved unpredictably on stdout. Verbose listing uses buffered stdio (printf()/puts()), while file contents are written directly to the stdout file descriptor. GNU tar also combines buffered verbose output with unbuffered writes for "-vO", however, GNU tar writes verbose output to stderr, so the two streams remain separate and consistent. Fix this by making "tar xvO" send output to stderr. function old new delta header_verbose_list 244 279 +35 header_list 15 49 +34 get_header_tar 1764 1769 +5 header_verbose_list_ar 77 78 +1 get_header_ar 542 540 -2 get_header_cpio 959 948 -11 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/2 up/down: 75/-13) Total: 62 bytes Signed-off-by: Thorsten B <brehmt@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* 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().

| | | | | | | | | | | | | | | 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>
