* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm: KVM: Fix off-by-one when writing to a nonpae guest pde

由 Avi Kivity 提交于
Nonpae guest pdes are shadowed by two pae ptes, so we double the offset twice: once to account for the pte size difference, and once because we need to shadow pdes for a single guest pde. But when writing to the upper guest pde we also need to truncate the lower bits, otherwise the multiply shifts these bits into the pde index and causes an access to the wrong shadow pde. If we're at the end of the page (accessing the very last guest pde) we can even overflow into the next host page and oops. Signed-off-by: NAvi Kivity <avi@qumranet.com>

There is a race between netlink_dump_start() and netlink_release() that can lead to the situation when a netlink socket with non-zero callback is freed. Here it is: CPU1: CPU2 netlink_release(): netlink_dump_start(): sk = netlink_lookup(); /* OK */ netlink_remove(); spin_lock(&nlk->cb_lock); if (nlk->cb) { /* false */ ... } spin_unlock(&nlk->cb_lock); spin_lock(&nlk->cb_lock); if (nlk->cb) { /* false */ ... } nlk->cb = cb; spin_unlock(&nlk->cb_lock); ... sock_orphan(sk); /* * proceed with releasing * the socket */ The proposal it to make sock_orphan before detaching the callback in netlink_release() and to check for the sock to be SOCK_DEAD in netlink_dump_start() before setting a new callback.

This patch fixes an oops first reported in mid 2006 - see http://lkml.org/lkml/2006/8/29/358 The cause of this bug report is that when an error is signalled on the socket, irda_recvmsg_stream returns without removing a local wait_queue variable from the socket's sk_sleep queue. This causes havoc further down the road. In response to this problem, a patch was made that invoked sock_orphan on the socket when receiving a disconnect indication. This is not a good fix, as this sets sk_sleep to NULL, causing applications sleeping in recvmsg (and other places) to oops. This is against the latest net-2.6 and should be considered for -stable inclusion.

The way partial delivery is currently implemnted, it is possible to intereleave a message (either from another steram, or unordered) that is not part of partial delivery process. The only way to this is for a message to not be a fragment and be 'in order' or unorderd for a given stream. This will result in bypassing the reassembly/ordering queues where things live duing partial delivery, and the message will be delivered to the socket in the middle of partial delivery. This is a two-fold problem, in that: 1. the app now must check the stream-id and flags which it may not be doing. 2. this clearing partial delivery state from the association and results in ulp hanging. This patch is a band-aid over a much bigger problem in that we don't do stream interleave. Signed-off-by: NVlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: NDavid S.

In mthca_arbel_fmr_unmap(), the high bits of the key are masked off. This gets rid of the effect of adjust_key(), which makes sure that bits 3 and 23 of the key are equal when the Sinai throughput optimization is enabled, and so it may happen that an FMR will end up with bits 3 and 23 in the key being different. This causes data corruption, because when enabling the throughput optimization, the driver promises the HCA firmware that bits 3 and 23 of all memory keys will always be equal. Fix by re-applying adjust_key() after masking the key. Thanks to Or Gerlitz for reproducing the problem, and Ariel Shahar for help in debug. Signed-off-by: NMichael S.
