* fixdep: add fstat error handlingSam James2024-09-271-2/+9
| | | | | | | | | | | | | | | | | | | | | When `fstat` fails, `st` is left uninitialised. In our case, Ben Kohler noticed our release media builds were failing in Gentoo on x86 when building busybox with occasional SIGBUS. This turned out to be EOVERFLOW (from 32-bit ino_t) which wasn't being reported because nothing was checking the return value from `fstat`. Fix that to avoid UB (use of uninit var) and to give a more friendly error to the user. This actually turns out to be fixed already in the kernel from back in 2010 [0] and 2016 [1].

* libbb: use full_write1_str() to shrink busybox_main()Ron Yorston2024-09-271-13/+11
| | | | | | | | | | | | | | | | | | | | | | There are two calls to dup2() in busybox_main(). These were introduced to coerce full_write2_str() into writing to stdout. The relevant commits were: 21278dff7 (busybox: do not print help to fd 2, print it to fd 1) and 5a7c72015 (busybox --list option. +140 bytes. Rob wanted it.) Later, in commit 729ecb87b (bbconfig: make it independent from printf functions), the function full_write1_str() was added. Using this in busybox_main() allows us to drop the dup2() calls. function old new delta run_applet_and_exit 796 760 -36 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-36) Total: -36 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* ash: fix parsing of alias expansion + bash featuresRon Yorston2024-07-101-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An alias expansion immediately followed by '<' and a newline is parsed incorrectly: ~ $ alias x='echo yo' ~ $ x< yo ~ $ sh: syntax error: unexpected newline The echo is executed and an error is printed on the next command submission. In dash the echo isn't executed and the error is reported immediately: $ alias x='echo yo' $ x< dash: 3: Syntax error: newline unexpected $ The difference between BusyBox and dash is that BusyBox supports bash-style process substitution and output redirection. These require checking for '<(', '>(' and '&>' in readtoken1(). In the case above, when the end of the alias is found, the '<' and the following newline are both read to check for '<('. Since there's no match both characters are pushed back. The next input is obtained by reading the expansion of the alias. Once this string is exhausted the next call to __pgetc() calls preadbuffer() which pops the string, reverts to the previous input and recursively calls __pgetc(). This request is satisified from the pungetc buffer. But the first __pgetc() doesn't know this: it sees the character has come from preadbuffer() so it (incorrectly) updates the pungetc buffer. Resolve the issue by moving the code to pop the string and fetch the next character up from preadbuffer() into __pgetc(). function old new delta pgetc 28 589 +561 __pgetc 607 - -607 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 1/0 up/down: 561/-607) Total: -46 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* docproc: avoid segfault during file closingYan Zhu2024-04-131-0/+1
| | | | | | | | | In the function find_export_symbols, since the fopen file does not exit when it fails, there is a dereference problem in fclose(fp), which will cause a segmentation fault. Signed-off-by: Yan Zhu <zhuyan2015@foxmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
