Hi Erik, Hi to all, This is part five of the my_get*id story. I've tweaked a bit this two functions to make them more flexible, but this changes will not affect existing code. Now they work so: 1) my_getpwuid( char *user, uid_t uid, int bufsize) if bufsize is > 0 char *user cannot be set to NULL on success username is written on static allocated buffer on failure uid as string is written to buffer and NULL is returned if bufsize is = 0 char *user can be set to NULL on success username is returned on failure NULL is returned if bufsize is < 0 char *user can be set to NULL on success username is returned on failure an error message is printed and the program exits 2) 1) my_getgrgid( char *group, uid_t uid, int bufsize) if bufsize is > 0 char *group cannot be set to NULL on success groupname is written on static allocated buffer on failure gid as string is written to buffer and NULL is returned if bufsize is = 0 char *group can be set to NULL on success groupname is returned on failure NULL is returned if bufsize is < 0 char *group can be set to nULL on success groupname is returned on failure an error message is printed and the program exits This changes were needed mainly for my new id applet. It is somewhat bigger then the previous but matches the behaviour of GNU id and is capable to handle usernames of whatever length. BTW: at a first look it seems to me that it will integrate well (with just a few changes) with the pending patch in patches/id_groups_alias.patch. The increase in size is balanced by the removal of my_getpwnamegid.c from libbb as this was used only in previous id applet and by size optimizations made possible in whoami.c and in passwd.c. I know that we are in feature freeze but I think that i've tested it enough (at least I hope so.......).

Hi, I've fixed also the issue of whoami cutting down usernames. This time I cannot send a diff because i don't know if my previous patches will be applied or not, so I send in the whole file. The changes I've made don't affect size but ensure that usernames of whatever lenght are correctly displayed. root@localhost:/dev/pts/3:/root/Desktop/busybox/coreutils# size whoami_orig.o text data bss dec hex filename 102 0 0 102 66 whoami_orig.o root@localhost:/dev/pts/3:/root/Desktop/busybox/coreutils# size whoami.o text data bss dec hex filename 93 0 0 93 5d whoami.o This should be applied even if the other patches aren't as this matches the behaviour of the GNU whoami. Thanks in advance, Ciao, Tito

Hi, I've spent the half night staring at the devilish my_getpwuid and my_getgrgid functions trying to find out a way to avoid actual and future potential buffer overflow problems without breaking existing code. Finally I've found a not intrusive way to do this that surely doesn't break existing code and fixes a couple of problems too. The attached patch: 1) changes the behaviour of my_getpwuid and my_getgrgid to avoid potetntial buffer overflows 2) fixes all occurences of this function calls in tar.c , id.c , ls.c, whoami.c, logger.c, libbb.h. 3) The behaviour of tar, ls and logger is unchanged. 4) The behavior of ps with somewhat longer usernames messing up output is fixed. 5) The only bigger change was the increasing of size of the buffers in id.c to avoid false negatives (unknown user: xxxxxx) with usernames longer than 8 chars. The value i used ( 32 chars ) was taken from the tar header ( see gname and uname). Maybe this buffers can be reduced a bit ( to 16 or whatever ), this is up to you. 6) The increase of size of the binary is not so dramatic: size busybox text data bss dec hex filename 239568 2300 36816 278684 4409c busybox size busybox_fixed text data bss dec hex filename 239616 2300 36816 278732 440cc busybox 7) The behaviour of whoami changed: actually it prints out an username cut down to the size of the buffer. This could be fixed by increasing the size of the buffer as in id.c or avoid the use of my_getpwuid and use getpwuid directly instead. Maybe this colud be also remain unchanged...... Please apply if you think it is ok to do so. The diff applies on today's cvs tarball (2004-08-25). Thanks in advance, Ciao, Tito

Hi to all, This patch is useful for: 1) remove an unused var from extern char *find_real_root_device_name(const char* name) changing it to extern char *find_real_root_device_name(void). 2) fixes include/libbb.h, coreutils/df.c, util-linux/mount.c and util-linux/umount.c accordingly. 3) fixes a bug, really a false positive, in find_real_root_device_name() that happens if in the /dev directory exists a link named root (/dev/root) that should be skipped but is not. This affects applets like df that display wrong results

2004-07-26BusyBox has no business hard coding the number of major and minor bits for aEric Andersen
dev_t. This is especially important now that the user space concept of a dev_t and the kernel concept of a dev_t are divergant. The only bit of user space allowed to know the number of major and minor bits is include/sys/sysmacros.h (i.e. part of libc). When used with a current C library and a 2.6.x kernel, this fix should allow BusyBox to support wide device major/minor numbers. -Erik

Hi, I just re-reviewed the patch I just sent...and it needed to be BUFSIZ-3 in dos2unix.c . tempFn is BUFSIZ so the last addressable spot it BUFSIZ-1. The loop increments by 2. That's why it should be BUFSIZ-3. Best Regards, Steve Grubb

Hello, I found and patched 2 more bugs. The first is a misplaced semi-colon. The second one is a buffer overflow. I doubt the buffer overflow is triggered in real life. But you never know what those wily hackers are up to. Thanks, Steve Grubb

This is a bulk spelling fix patch against busybox-1.00-pre10. If anyone gets a corrupted copy (and cares), let me know and I will make alternate arrangements. Erik - please apply. Authors - please check that I didn't corrupt any meaning. Package importers - see if any of these changes should be passed to the upstream authors. I glossed over lots of sloppy capitalizations, missing apostrophes, mixed American/British spellings, and German-style compound words. What is "pretect redefined for test" in cmdedit.c? Good luck on the 1.00 release! - Larry

I've noticed a bug in the "autowidth" feature more, and is probably in others. The call to the function get_terminal_width_height() passes in a file descriptor but that file descriptor is never used, instead the ioctl() is called with 0. In more_main() the call to get_terminal_width_height() passes 0 as the file descriptor instead of fileno(cin). This isn't a problem when you more a file (e.g. "more /etc/passwd") but when you pipe a file to it (e.g. "cat /etc/passwd | more") the size of the terminal cannot be determined because file descriptor 0 is not a terminal. The fix is simple, I've attached a patch for more.c and get_terminal_width_height.c. BAPper
