2005-01-04Dear andersen:Eric Andersen
Is the change on libbb/loop.c which you commited in 2005/1/3 effective really? The __GLIBC__ macro and __UCLIBC__ macro are defined in feature.h in glibc source, so the change may not be effective. If you want to check this with __GLIBC__, feature.h header is needed. Some architectures(e.g. PPC series) need to include linux/posix_types.h in stead of asm/posix_types.h, so the patch which is attached with this mail include <linux/posix_types.h>.

Hi to all, This patch contains just some fixes for some misleading comments in my_getpwuid.c and my_getug.c. The code is untouched so this patch will not cause troubles. Please apply. Thanks in advance and Ciao, Tito

Hi! I've created a patch to busybox' build system to allow building it in separate tree in a manner similar to kbuild from kernel version 2.6. That is, one runs command like 'make O=/build/some/where/for/specific/target/and/options' and everything is built in this exact directory, provided that it exists. I understand that applyingc such invasive changes during 'release candidates' stage of development is at best unwise. So, i'm currently asking for comments about this patch, starting from whether such thing is needed at all to whether it coded properly. 'make check' should work now, and one make creates Makefile in build directory, so one can run 'make' in build directory after that. One possible caveat is that if we build in some directory other than source one, the source directory should be 'distclean'ed first. egor
2004-10-08Patch from Michael Tokarev:Eric Andersen
Scenario: touch x -- creates plain file name `x' mkdir x -- exits successefully libbb/make_directory.c, bb_make_directory(), contains the following code: if (mkdir(path, 0777) < 0) { /* If we failed for any other reason than the directory * already exists, output a diagnostic and return -1.*/ if (errno != EEXIST) { fail_msg = "create"; umask(mask); break; } /* Since the directory exists, don't attempt to change * permissions if it was the full target. Note that * this is not an error conditon. */ if (!c) { umask(mask); return 0; } } The assumption that EEXIST error is due to that the *directory* already exists is wrong: any file type with that name will cause this error to be returned. Proper way IMHO will be is to stat() the path and check whenever this is really a directory. Below (attached) is a patch to fix this issue.

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 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

I've reversed the patch and now everything is working again. I compared the get_name's return values from the 1.23 and 1.24 and quickly noticed that the new revision is leaving `p' right on the sep while the rev 1.23 was leaving it right on the starting of the values... 1-line, 1/3-minute patch attached :-)
2004-08-16Use __kernel_old_dev_t for 2.6.x kernelsEric Andersen
2004-08-16Aurelien Jacobs writes:Eric Andersen
with a quick conversion you will see that 132608 == 0x20600 so noticed that the elif will never be matched ! Apparently there was already a try to modify this in CVS which was reverted (it was plain wrong). I don't know when __kernel_old_dev_t is needed, but with a 2.6.7 or a 2.6.8 this is __kernel_dev_t wich is needed. I corrected this with the following patch but maybe older 2.6 still need __kernel_old_dev_t ? I think this should be corrected before 1.0. Thanks Aurel

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

The linux kernel doesnt allow hard links to directories, SUS says its implementation specific. cramfs gives empty directories and 0 length files the same node it makies it difficult to distinguish from hard links.

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

Test for demonstrate: $ mkdir aaa bbb ccc $ su # chown root bbb # chmod 700 bbb # exit $ busybox chmod 777 -R . ./bbb: Permision denied But "./ccc" mode not changed. Previous variant works fine, errors skiped and continued recursion. --w vodz

Hello everyone, Busybox's insmod fails to locate a module when that module is the only one existing in the /lib/modules directory (with a unique name). Example: # find /lib/modules/ -type f /lib/modules/kernel/drivers/char/bios.o # insmod bios insmod: bios.o: no module by that name found # touch /lib/modules/dummy # find /lib/modules/ -type f /lib/modules/kernel/drivers/char/bios.o /lib/modules/dummy # insmod bios Using /lib/modules/kernel/drivers/char/bios.o As long as there is another file in the /lib/modules directory, insmod finds it OK. I tracked the problem down to 'check_module_name_match()' in insmod.c: It returns TRUE when a match is found, and FALSE otherwise. In the case where there is only one module in the /lib/modules directory (or more that one module, but all with the same name), 'recursive_action()' will return TRUE and we end up on line 4196 in 'insmod.c' which returns an error. [The reason it works with more than one module with different names is that in this case there will always be one not matching, 'recursive_action()' will return FALSE and we end up in line 4189.] Now, from the implementation of 'recursive_action()' and from other usages of it (tar.c, etc.), it seems to me that FALSE should be returned to indicate that we want to stop the recursion, so TRUE and FALSE should be inverted in 'check_module_name_match()'. At the same time, 'recursive_action()' continues to recurse even after the recursive call has returned FALSE; again in my understanding and other usages of it, we can safely stop recursing at this point. Here is my patch against 1.00-pre8:

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

The off_t type is not a consistent size; it depends on the kernel options (something about large file support). Therefore, the format string for printing an address is not always the same.
