* mac80211: fix debugfs key->station symlinkJohannes Berg2012-01-181-3/+4

* tg3: Fix single-vector MSI-X codeMatt Carlson2012-01-171-13/+14
| | | | | | | | | | | | | | | Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel) enabled. However, kdump only enables one CPU in the new environment, thus causing tg3 to abort MSI-X setup. When the driver attempts to enable INTA or MSI interrupt modes on a kdump kernel, interrupt delivery fails. This patch attempts to workaround the problem by forcing the driver to enable a single MSI-X interrupt. In such a configuration, the device's multivector interrupt mode must be disabled.

* openvswitch: Fix multipart datapath dumps.Ben Pfaff2012-01-171-4/+3
| | | | | | | | | | | | The logic to split up the list of datapaths into multiple Netlink messages was simply wrong, causing the list to be terminated after the first part. Only about the first 50 datapaths would be dumped. This fixes the problem.

* net: WARN if skb_checksum_help() is called on skb requiring segmentationBen Hutchings2012-01-171-12/+19
| | | | | | | | | | | | | | skb_checksum_help() has never done anything useful with skbs that require segmentation. Setting skb->ip_summed = CHECKSUM_NONE makes them invalid and provokes a later WARNing in skb_gso_segment(). Passing such an skb to skb_checksum_help() indicates a bug, so we should warn about it immediately. Move the warning from skb_gso_segment() into a shared function, and add gso_type and gso_size to it. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We may leak the 'fwd_skb' we skb_copy() in ieee80211_rx_h_mesh_fwding() if we take the 'else' branch in the 'if' statement just below. If we take that branch we'll end up returning from the function and since we've not assigned 'fwd_skb' to anything at that point, we leak it when the variable goes out of scope. The simple fix seems to be to just kfree_skb(fwd_skb); just before we return. That is what this patch does. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | Documentation states that the KeyMiss flag is only valid if RxFrameOK is unset, however empirical evidence has shown that this is false. When KeyMiss is set (and RxFrameOK is 1), the hardware passes a valid frame which has not been decrypted. The driver then falsely marks the frame as decrypted, and when using CCMP this corrupts the rx CCMP PN, leading to connection hangs.

| * mac80211: fix no-op authorized transitionsJohannes Berg2012-01-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When userspace attempts to authorize a station that is already authorized, nothing happens as you'd expect. Similarly, when it unauthorizes a station that is associated, nothing happens. However, when it unauthorizes a station that isn't even associated yet, we erroneously try to move the station to associated. This seems to happen occasionally as a result of a race when wpa_supplicant attempts to unauthorize the port in managed mode. Particularly with my new patches to keep stations, it can then move a station into ASSOCIATED state before we have really associated, which is really confusing.

| * rt2800pci: fix spurious interrupts generationStanislaw Gruszka2012-01-131-20/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Same devices can generate interrupt without properly setting bit in INT_SOURCE_CSR register (spurious interrupt), what will cause IRQ line will be disabled by interrupts controller driver. We discovered that clearing INT_MASK_CSR stops such behaviour. We previously first read that register, and then clear all know interrupt sources bits and do not touch reserved bits. After this patch, we write to all register content (I believe writing to reserved bits on that register will not cause any problems, I tested that on my rt2800pci device). This fix very bad performance problem, practically making device unusable (since worked without interrupts), reported in: https://bugzilla.redhat.com/show_bug.cgi?id=658451 We previously tried to workaround that issue in commit 4ba7d9997869d25bd223dea7536fc1ce9fab3b3b "rt2800pci: handle spurious interrupts", but it was reverted in commit 82e5fc2a34fa9ffea38f00c4066b7e600a0ca5e6 as thing, that will prevent to detect real spurious interrupts.

| * ipw2x00: signedness bug handling frame lengthDan Carpenter2012-01-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is basically just a cleanup. Large positive numbers get counted as negative but then get implicitly cast to positive again for the checks that matter. This does make a small difference in ipw_handle_promiscuous_rx() when we test "if (unlikely((len + IPW_RX_FRAME_SIZE) > skb_tailroom(rxb->skb)))" It should return there, but we don't return until a couple lines later when we test "if (len > IPW_RX_BUF_SIZE - sizeof(struct ipw_rt_hdr)) {". The difference is that in the second test the sizeof() means that there is an implied cast to unsigned.

Moreover, a new infrastructure will be submitted for the 3.3.x development cycle that resolve the existing issues while providing a neat solution. Since nobody has been seriously using this infrastructure in user-space, the removal of this feature should affect any know FOSS project (to my knowledge).

* | vhost-net: add module alias (v2.1)stephen hemminger2012-01-133-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | By adding some module aliases, programs (or users) won't have to explicitly call modprobe. Vhost-net will always be available if built into the kernel. It does require assigning a permanent minor number for depmod to work. Also: - use C99 style initialization. - add missing entry in documentation for loop-control Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Acked-By: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: David S.

Then they merge the patch and the selftest code dies. Sometimes we paste it into the changelog. Sometimes the code gets thrown into Documentation/(!). This saddens me. So this patch creates a bare-bones framework which will henceforth allow me to ask people to include their test apps in the kernel tree so we can keep them alive. Then when people enhance or fix the feature, I can ask them to update the test app too. The infrastruture is terribly trivial at present - let's see how it evolves. - checkpoint/restart feature work. A note on this: this is a project by various mad Russians to perform c/r mainly from userspace, with various oddball helper code added into the kernel where the need is demonstrated. So rather than some large central lump of code, what we have is little bits and pieces popping up in various places which either expose something new or which permit something which is normally kernel-private to be modified. The overall project is an ongoing thing. I've judged that the size and scope of the thing means that we're more likely to be successful with it if we integrate the support into mainline piecemeal rather than allowing it all to develop out-of-tree. However I'm less confident than the developers that it will all eventually work! So what I'm asking them to do is to wrap each piece of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all eventually comes to tears and the project as a whole fails, it should be a simple matter to go through and delete all trace of it. This lot pretty much wraps up the -rc1 merge for me. * akpm: (96 commits) unlzo: fix input buffer free ramoops: update parameters only after successful init ramoops: fix use of rounddown_pow_of_two() c/r: prctl: add PR_SET_MM codes to set up mm_struct entries c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4 c/r: introduce CHECKPOINT_RESTORE symbol selftests: new x86 breakpoints selftest selftests: new very basic kernel selftests directory radix_tree: take radix_tree_path off stack radix_tree: remove radix_tree_indirect_to_ptr() dio: optimize cache misses in the submission path vfs: cache request_queue in struct block_device fs/direct-io.c: calculate fs_count correctly in get_more_blocks() drivers/parport/parport_pc.c: fix warnings panic: don't print redundant backtraces on oops sysctl: add the kernel.ns_last_pid control kdump: add udev events for memory online/offline include/linux/crash_dump.h needs elf.h kdump: fix crash_kexec()/smp_send_stop() race in panic() kdump: crashk_res init check for /sys/kernel/kexec_crash_size ...
