* | | exec.c: fix coredump to pipe problem and obscure "security hole"Alan Cox2007-04-171-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch checks for "|" in the pattern not the output and doesn't nail a pid on to a piped name (as it is a program name not a file) Also fixes a very very obscure security corner case. If you happen to have decided on a core pattern that starts with the program name then the user can run a program called "|myevilhack" as it stands. I doubt anyone does this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the writebacks are cancelled via nfs_cancel_dirty_list, or due to the memory allocation failing in nfs_flush_one/nfs_flush_multi, then we must ensure that the PG_writeback flag is cleared. Also ensure that we actually own the PG_writeback flag whenever we schedule a new writeback by making nfs_set_page_writeback() return the value of test_set_page_writeback(). The PG_writeback page flag ends up replacing the functionality of the PG_FLUSHING nfs_page flag, so we rip that out too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 3w-xxxx emulates a REQUEST_SENSE response by simply returning nothing. Unfortunately, it's assuming that the REQUEST_SENSE command is implemented with use_sg == 0, which is no longer the case. The oops occurs because it's clearing the scatterlist in request_buffer instead of the memory region. This is fixed by using tw_transfer_internal() to transfer correctly to the scatterlist.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DVB USB remotes do not support changing keycode maps but set input_dev->keycodesize and input_dev->keycodemax without setting input_dev->keycode. This causes kernel oops when user tries to look up (or change) current keymap. While the proper fix would be to make remotes handle keymap changes we'll just remove keycodemax and keycodesize initialization so EVIOCGKEYCODE and EVIOCSKEYCODE will simply return -EINVAL. http://bugzilla.kernel.org/show_bug.cgi?id=8312 Signed-off-by: olaf.kirch@oracle.com Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

But I'm getting rid of uses of the OPEN_MAX and CHILD_MAX compile-time constant, and these are almost the only ones. OPEN_MAX is a bogus constant with no meaning about anything. The RLIMIT_NOFILE resource limit is what sysconf (_SC_OPEN_MAX) actually wants to return. The CHILD_MAX cases weren't actually using anything I want to get rid of, but I noticed that they are there and are wrong too. The CHILD_MAX value is not really unlimited as a -1 return from sysconf indicates. The RLIMIT_NPROC resource limit is what sysconf (_SC_CHILD_MAX) wants to return.

Instead of trying to fix this overly complicated code, just mirror the PCI IOMMU arena allocator which is very stable and well stress tested. I tried to make the code as identical as possible so we can switch sun4u PCI and SBUS over to a common piece of IOMMU code. All that will be need are two callbacks, one to do a full IOMMU flush and one to do a streaming buffer flush. This patch gets rid of a lot of hangs and mysterious crashes on SBUS sparc64 systems, at least for me. Signed-off-by: David S. Miller <davem@davemloft.net>

This is caused by the VLAN driver not setting the 'protocol' and 'nh' members of the sk_buff structure.

* | | [PATCH] autofs4: fix race in unhashed dentry codeJeff Mahoney2007-04-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f50b6f8691cae2e0064c499dd3ef3f31142987f0 introduced a race in autofs4 between autofs_lookup_unhashed() and autofs_dentry_release(). autofs_dentry_release() ends up clearing the ->dentry and ->inode members of autofs_info before removing it from the rehash list. The list is protected by the rehash lock in both functions, but since autofs_dentry_release() starts tearing the autofs_info struct down before removing it from the list, autofs_lookup_unhashed() can get a autofs_info with a NULL dentry. This patch moves the clearing of ->dentry and ->inode after the removal from the rehash list.

* | | [PATCH] reiserfs: fix key decrementingVladimir Saveliev2007-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug in function decrementing a key of stat data item. Offset of reiserfs keys are compared as signed values. To set key offset to maximal possible value maximal signed value has to be used. This bug is responsible for severe reiserfs filesystem corruption which shows itself as warning vs-13060. reiserfsck fixes this corruption by filesystem tree rebuilding.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If 'num_pages' were ever 1 more than a multiple of 8 (32bit platforms) or of 16 (64 bit platforms). filemap_attr would be allocated one 'unsigned long' shorter than required. We need a round-up in there.
