| | | | | | | | It is impossible to formulate sane ABI based on size of ulong because it can be 32-bit or 64-bit. Basically it means that you cannot portably use more that 32 option chars in one call anyway... Make it explicit.

* Patch from Colin Watson (mangled slightly by Rob Landley):Rob Landley2005-05-181-6/+10
| | | | | | | | | | This patch implements the 'T' command in sed. This is a GNU extension, but one of the udev hotplug scripts uses it, so I need it in busybox anyway. Includes a test; 'svn add testsuite/sed/sed-branch-conditional-inverted' after applying.
* Doug Swarin pointed out a security bug in the -i option of sed.Rob Landley2005-05-181-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the permissions on the temp file are correct to prevent it from being maliciously mangled by passing strangers, (created with 600, opened O_EXCL, etc), the permissions on the _directory_ might not be, and we re-open the file to convert the filehandle to a FILE * (and automatically get an error message and exit if the directory's read-only or out of space or some such). This opens a potential race condition if somebody's using dnotify on the directory, deletes/renames the tempfile, and drops a symlink or something there. Somebody running sed -i as root in a world writeable directory could do damage. I dug up notes on an earlier discussion where we looked at the security implications of this (unfortunately on the #uclibc channel rather than email; I don't have a transcript, just notes-to-self) which pointed out that if the permissions on the directory allow other people's files to be deleted/renamed then the original file is vulnerable to sabotage anyway. However, there are two cases that discussion apparently didn't take into account: 1) Using another user's permissions to damage files in other directories you can't access (standard symlink attack). 2) Reading data another user couldn't otherwise access by having the new file belong to that other user. This patch uses fdopen to convert the filehandle into a FILE *, rather than reopening the file.

* Hiroshi found another bug. Currently sed's $ triggers at end of every file,Rob Landley2004-11-251-28/+46
| | | | | | | | | | | | | | | | | | | | | | | | and with multiple files SuSv3 says it should only trigger at the end of the LAST file. The trivial fix I tried first broke if the last file is empty. Fixing this properly required restructuring things to create a file list (actually a FILE * list), and then processing it all in one go. (There's probably a smaller way to do this, merging with append_list perhaps. But let's get the behavior correct first.) Note that editing files in place (-i) needs the _old_ behavior, with $ triggering at the end of each file. Here's a test of all the things this patch fixed. gnu and busybox seds produce the same results with this patch, and different without it. echo -n -e "1one\n1two\n1three" > ../test1 echo -n > ../test2 echo -e "3one\n3two\n3three" > ../test3 sed -n "$ p" ../test1 ../test2 ../test3 sed -n "$ p" ../test1 ../test2 sed -i -n "$ p" ../test1 ../test2 ../test3
