* vfs: fix unconditional write_super() call in file_fsync()OGAWA Hirofumi2008-04-291-1/+1
| | | | | | | | | | | | | We need to check ->s_dirt before calling write_super(). It became the cause of an unneeded write. This bug was noticed by Sudhanshu Saxena.

* vfs: fix lock inversion in drop_pagecache_sb()Jan Kara2008-04-291-1/+7
| | | | | | | | | | | | | | Fix longstanding lock inversion in drop_pagecache_sb by dropping inode_lock before calling __invalidate_mapping_pages(). We just have to make sure inode won't go away from under us by keeping reference to it and putting the reference only after we have safely resumed the scan of the inode list. A bit tricky but not too bad...

* binfmt_misc.c: avoid potential kernel stack overflowPavel Emelyanov2008-04-293-2/+8
| | | | | | | | | | | | | | | | | | | | | | This can be triggered with root help only, but... Register the ":text:E::txt::/root/cat.txt:' rule in binfmt_misc (by root) and try launching the cat.txt file (by anyone) :) The result is - the endless recursion in the load_misc_binary -> open_exec -> load_misc_binary chain and stack overflow. There's a similar problem with binfmt_script, and there's a sh_bang memner on linux_binprm structure to handle this, but simply raising this in binfmt_misc may break some setups when the interpreter of some misc binaries is a script. So the proposal is to turn sh_bang into a bit, add a new one (the misc_bang) and raise it in load_misc_binary. After this, even if we set up the misc -> script -> misc loop for binfmts one of them will step on its own bang and exit.

* exec: remove argv_len from struct linux_binprmTetsuo Handa2008-04-291-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | I noticed that 2.6.24.2 calculates bprm->argv_len at do_execve(). But it doesn't update bprm->argv_len after "remove_arg_zero() + copy_strings_kernel()" at load_script() etc. audit_bprm() is called from search_binary_handler() and search_binary_handler() is called from load_script() etc. Thus, I think the condition check if (bprm->argv_len > (audit_argv_kb << 10)) return -E2BIG; in audit_bprm() might return wrong result when strlen(removed_arg) != strlen(spliced_args). Why not update bprm->argv_len at load_script() etc. ? By the way, 2.6.25-rc3 seems to not doing the condition check. Is the field bprm->argv_len no longer needed?

* epoll: avoid kmemcheck warningDavide Libenzi2008-04-291-24/+3
| | | | | | | | | | | | | | | | Epoll calls rb_set_parent(n, n) to initialize the rb-tree node, but rb_set_parent() accesses node's pointer in its code. This creates a warning in kmemcheck (reported by Vegard Nossum) about an uninitialized memory access. The warning is harmless since the following rb-tree node insert is going to overwrite the node data. In any case I think it's better to not have that happening at all, and fix it by simplifying the code to get rid of a few lines that became superfluous after the previous epoll changes.

* fat: detect media without partition table correctlyFrank Seidel2008-04-281-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I received a complaint that some FAT formated medias (e.g. sd memory cards) trigger a "unknown partition table" message even though there is no partition table and they work correctly, while in general (when e.g. formated with mkdosfs or even Windows Vista) this message is not shown. Currently this seems only to happen when the medias get formatted with Windows XP (and possibly Win 2000). Then the boot indicator byte contains garbage (part of text message) and so do the other parts checked by msdos_paritition which then later triggers this message. References: novell bug #364365 Most fat formatted media without partition table contains zeros in the boot indication and the other tested bytes and so falls through the checks in msdos_partition, leading it to return with 1 (all is fine). But some (e.g. WinXP formatted) fat fomated medias don't use boot_ind and so the check fails and causes a "unkown partition table" warning eventhough there is none and everything would be fine. This additional check directly verifies if there is a fat formatted medium without a partition table.

* reiserfs: unpack tails on quota filesJan Kara2008-04-282-8/+13
| | | | | | | | | | | | | | | | | Quota files cannot have tails because quota_write and quota_read functions do not support them. So far when quota files did have tail, we just refused to turn quotas on it. Sadly this check has been wrong and so there are now plenty installations where quota files don't have NOTAIL flag set and so now after fixing the check, they suddently fail to turn quotas on. Since it's easy to unpack the tail from kernel, do this from reiserfs_quota_on() which solves the problem and is generally nicer to users anyway.

* reiserfs: fix hang on umount with quotas when journal is abortedJan Kara2008-04-281-1/+7
| | | | | | | | | | Call dquot_drop() from reiserfs_dquot_drop() even if we fail to start a transaction. Otherwise we never get to dropping references to quota structures from the inode and umount will hang indefinitely.
