Package: dash
Version: 0.5.6.1-1~exp0
Severity: critical
When user doesn't have write access to script :
sob...@solis:/tmp$ ls -lh ./a.sh
-r-xr-x--- 1 sobkas sobkas 9 06-22 19:20 ./a.sh
dash fails to start it with this error(I have dash as sh)
sob...@solis:/tmp$ ./a.sh
/bin/sh: Can't open ./a.sh
During the boot-up process / partition is read-only and because of that
dash is unable to execute /etc/init.d/rcS and /etc/init.d/rc scripts.
Apparently problem lies inside patch:
0006--INPUT-exit-127-if-command_file-is-given-but-doesn-t.diff
Why would anyone want to open script in read-write mode?
- if ((fd = open(fname, O_RDONLY)) < 0) {
+ if ((fd = open(fname, O_RDWR)) < 0) {
After changing it back to O_RDONLY dash properly executes read-only scripts.
