| | | | | | | | | | | | | | | | | | | | | | | | | | | The most important property we need from nfs_attr_generation_counter is monotonicity, which is not guaranteed by the current system of smp memory barriers. We should convert it to an atomic_long_t, and drop the memory barriers. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| * | ecryptfs: fix memory corruption when storing crypto info in xattrsEric Sandeen2008-10-301-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ecryptfs allocates space to write crypto headers into, before copying it out to file headers or to xattrs, it looks at the value of crypt_stat->num_header_bytes_at_front to determine how much space it needs. This is also used as the file offset to the actual encrypted data, so for xattr-stored crypto info, the value was zero. So, we kzalloc'd 0 bytes, and then ran off to write to that memory. (Which returned as ZERO_SIZE_PTR, so we explode quickly). The right answer is to always allocate a page to write into; the current code won't ever write more than that (this is enforced by the (PAGE_CACHE_SIZE - offset) length in the call to ecryptfs_generate_key_packet_set). To be explicit about this, we now send in a "max" parameter, rather than magically using PAGE_CACHE_SIZE there. Also, since the pointer we pass down the callchain eventually gets the virt_to_page() treatment, we should be using a alloc_page variant, not kzalloc (see also 7fcba054373d5dfc43d26e243a5c9b92069972ee) Signed-off-by: Eric Sandeen <sandeen@redhat.com> Acked-by: Michael Halcrow <mhalcrow@us.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | The iscsi_ibft.c changes are almost certainly a bugfix as the pointer 'ip' is a u8 *, so they never print the last 8 bytes of the IPv6 address, and the eight bytes they do print have a zero byte with them in each 16-bit word. Other than that, this should cause no difference in functionality. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* epoll: avoid double-inserts in case of EFAULTDavide Libenzi2008-10-261-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | In commit f337b9c58332bdecde965b436e47ea4c94d30da0 ("epoll: drop unnecessary test") Thomas found that there is an unnecessary (always true) test in ep_send_events(). The callback never inserts into ->rdllink while the send loop is performed, and also does the ~EP_PRIVATE_BITS test. Given we're holding the mutex during this time, the conditions tested inside the loop are always true. HOWEVER. The test "!ep_is_linked(&epi->rdllink)" wasn't there because we insert into ->rdllink, but because the send-events loop might terminate before the whole list is scanned (-EFAULT). In such cases, when the loop terminates early, and when a (leftover) file received an event while we're performing the lockless loop, we need such test to avoid to double insert the epoll items. The list_splice() done a few steps below, will correctly re-insert the ones that were left on "txlist". This should fix the kenrel.org bugzilla entry 11831.

* select: deal with math overflow from borderline valid userland dataArjan van de Ven2008-10-262-4/+6
| | | | | | | | | | | | | | | | | | | | Some userland apps seem to pass in a "0" for the seconds, and several seconds worth of usecs to select(). The old kernels accepted this just fine, so the new kernels must too. However, due to the upscaling of the microseconds to nanoseconds we had some cases where we got math overflow, and depending on the GCC version (due to inlining decisions) that actually resulted in an -EINVAL return. This patch fixes this by adding the excess microseconds to the seconds field. Also with thanks to Marcin Slusarz for spotting some implementation bugs in the diagnostics patches.

* ext4: Fix duplicate entries returned from getdents() system callTheodore Ts'o2008-10-251-12/+8
| | | | | | | | | | | | | | | | | | | Fix a regression caused by commit d0156417, "ext4: fix ext4_dx_readdir hash collision handling", where deleting files in a large directory (requiring more than one getdents system call), results in some filenames being returned twice. This was caused by a failure to update info->curr_hash and info->curr_minor_hash, so that if the directory had gotten modified since the last getdents() system call (as would be the case if the user is running "rm -r" or "git clean"), a directory entry would get returned twice to the userspace.
