* [PATCH] readv/writev syscalls are not checked by lsmKostik Belousov2005-09-291-0/+3
| | | | | | | | | | | | | | it seems that readv(2)/writev(2) syscalls do not call file_permission callback. Looks like this is overlook. I have filled the issue into redhat bugzilla as https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169433 and got the recommendation to post this on lsm mailing list. The following trivial patch solves the problem. Signed-off-by: Kostik Belousov <kostikbel@gmail.com> Signed-off-by: Chris Wright <chrisw@osdl.org>

* [PATCH] v9fs: fix races in fid allocationLatchesar Ionkov2005-09-287-196/+200
| | | | | | | | | | | | | | | | | | | | Fid management cleanup. The patch attempts to fix the races in dentry's fid management. Dentries don't keep the opened fids anymore, they are moved to the file structs. Ideally there should be no more than one fid with fidcreate equal to zero in the dentry's list of fids. v9fs_fid_create initializes the important fields (fid, fidcreated) before v9fs_fid is added to the list. v9fs_fid_lookup returns only fids that are not created by v9fs_create. v9fs_fid_get_created returns the fid created by the same process by v9fs_create (if any) and removes it from dentry's list Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Cc: Eric Van Hensbergen <ericvh@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If error occurs while in v9fs_get_sb after it calles sget, the dentry object of the root and its inode may be freed twice -- once while handling the error in v9fs_get_sb, and second time when v9fs_get_sb calles deactivate_super (which in turn calls v9fs_kill_super) The patch removes the unnecessary code that frees the root dentry and its inode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v9fs_vfs_readlink allocates space for the link using __getname and errorneously uses strlen on the newly allocated buffer to check if the buffer passed by the user is bigger than the one returned by __getname.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a new session is created it uses a template object of the specified transport type to instantiate its own copy. The code for the making a copy of the template object was lost, and the object itself is attached to the v9fs session. This leads to many sessions using the same transport instead of having their own copy. The patch puts back the code that makes a copy of the template object.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | buf_check_size function checks if the conv buffer has enough space for the performed operation, but it doesn't return the result back to the calling function, only logs an error in the log. The report-back-error functionality was lost when buf_check_size was converted from macro to inline function. The return in the macro used to exit from the functions that include it, after the conversion it just exits from the inline function itself. The patch makes buf_check_size to return flag and all functions that use it check if they should perform the operation, or exit.

* | [PATCH] error path in setup_arg_pages() misses vm_unacct_memory()Hugh Dickins2005-09-141-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pavel Emelianov and Kirill Korotaev observe that fs and arch users of security_vm_enough_memory tend to forget to vm_unacct_memory when a failure occurs further down (typically in setup_arg_pages variants). These are all users of insert_vm_struct, and that reservation will only be unaccounted on exit if the vma is marked VM_ACCOUNT: which in some cases it is (hidden inside VM_STACK_FLAGS) and in some cases it isn't. So x86_64 32-bit and ppc64 vDSO ELFs have been leaking memory into Committed_AS each time they're run. But don't add VM_ACCOUNT to them, it's inappropriate to reserve against the very unlikely case that gdb be used to COW a vDSO page - we ought to do something about that in do_wp_page, but there are yet other inconsistencies to be resolved. The safe and economical way to fix this is to let insert_vm_struct do the security_vm_enough_memory check when it finds VM_ACCOUNT is set. And the MIPS irix_brk has been calling security_vm_enough_memory before calling do_brk which repeats it, doubly accounting and so also leaking. Remove that, and all the fs and arch calls to security_vm_enough_memory: give it a less misleading name later on.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that the BUG_ON() in fs/exec.c: de_thread() is unreliable and can trigger due to the test itself being racy. de_thread() does while (atomic_read(&sig->count) > count) { } ..... ..... BUG_ON(!thread_group_empty(current)); but release_task does write_lock_irq(&tasklist_lock) __exit_signal (this is where atomic_dec(&sig->count) is run) __exit_sighand __unhash_process takes write lock on tasklist_lock remove itself out of PIDTYPE_TGID list write_unlock_irq(&tasklist_lock) so there's a clear (although small) window between the atomic_dec(&sig->count) and the actual PIDTYPE_TGID unhashing of the thread. And actually there is no need for all threads to have exited at this point, so we simply kill the BUG_ON. Big thanks to Marc Lehmann who provided the test-case.
