* crypto: prefix module autoloading with "crypto-"Kees Cook2014-11-241-0/+13
| | | | | | | | | | | This prefixes all crypto module loading with "crypto-" so we never run the risk of exposing module auto-loading to userspace via a crypto API, as demonstrated by Mathias Krause: https://lkml.org/lkml/2013/3/4/70 Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized by boot loader and the kernel code defined fixed rates according to those default configurations. Beginning with the USB PLL7 the code started to initialize the PLL's itself (using imx_clk_pllv3). However, since commit dc4805c2e78ba5a22ea1632f3e3e4ee601a1743b (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver) imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits, hence the USB PLL were not configured correctly anymore. This patch not only fixes those USB PLL's, but also makes use of the imx_clk_pllv3 for all PLL's and alignes the code with the PLL support of the i.MX6 series.

| * | of: Fix overflow bug in string property parsing functionsGrant Likely2014-11-041-14/+70
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The string property read helpers will run off the end of the buffer if it is handed a malformed string property. Rework the parsers to make sure that doesn't happen. At the same time add new test cases to make sure the functions behave themselves. The original implementations of of_property_read_string_index() and of_property_count_strings() both open-coded the same block of parsing code, each with it's own subtly different bugs. The fix here merges functions into a single helper and makes the original functions static inline wrappers around the helper. One non-bugfix aspect of this patch is the addition of a new wrapper, of_property_read_string_array(). The new wrapper is needed by the device_properties feature that Rafael is working on and planning to merge for v3.19. The implementation is identical both with and without the new static inline wrapper, so it just got left in to reduce the churn on the header file.

With the restructuring of the m25p80.c driver and the SPI NOR library framework, we omitted proper listing of the SPI device IDs. This means m25p80.c wouldn't auto-load (modprobe) properly when built as a module. For now, we duplicate the device IDs into both modules. - The OMAP / ELM modules were depending on an implicit link ordering.

The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80.

Instead of returning a short read for a read that extends partially beyond the device's end or 0 when at the end of the device, these reads now return EIO. The raw driver needs the same end of device handling as was added for normal block devices. Using blkdev_read_iter, which has the needed size checks, prevents the EIO conditions at the end of the device.

From Ian Morgan. 4) Checking of skb_gso_segment()'s return value was not all encompassing, it can return an SKB pointer, a pointer error, or NULL. Fix from Florian Westphal. This is crummy, and longer term will be fixed to just return error pointers or a real SKB. 6) Encapsulation offloads not being handled by skb_gso_transport_seglen(). From Florian Westphal. 7) Fix deadlock in TIPC stack, from Ying Xue. 8) Fix performance regression from using rhashtable for netlink sockets. The problem was the synchronize_net() invoked for every socket destroy. From Thomas Graf. 9) Fix bug in eBPF verifier, and remove the strong dependency of BPF on NET.

Move the setting deeper to fix this. From Sathya Perla. 15) NAPI budget accounting in amd-xgbe driver was counting descriptors instead of full packets, fix from Thomas Lendacky. 16) Fix total_data_buflen calculation in hyperv driver, from Haiyang Zhang. 17) Fix bcma driver build with OF_ADDRESS disabled, from Hauke Mehrtens. 18) Fix mis-use of per-cpu memory in TCP md5 code. The problem is that something that ends up being vmalloc memory can't be passed to the crypto hash routines via scatter-gather lists. From Eric Dumazet. 19) Fix regression in promiscuous mode enabling in cdc-ether, from Olivier Blin. 20) Bucket eviction and frag entry killing can race with eachother, causing an unlink of the object from the wrong list. Fix from Nikolay Aleksandrov. 21) Missing initialization of spinlock in cxgb4 driver, from Anish Bhatt. 22) Do not cache ipv4 routing failures, otherwise if the sysctl for forwarding is subsequently enabled this won't be seen.

The patches are: 1) Fix a null-pointer dereference that may occur when logging errors. This problem was introduced by 4a4739d56b0 ("ipvs: Pull out crosses_local_route_boundary logic") in v3.17-rc5. 2) Update hook mask in nft_reject_bridge so we can also filter out packets from there. This fixes 36d2af5 ("netfilter: nf_tables: allow to filter from prerouting and postrouting"), which needs this chunk to work. 3) Two patches to refactor common code to forge the IPv4 and IPv6 reject packets from the bridge. These are required by the nf_tables reject bridge fix. 4) Fix nft_reject_bridge by avoiding the use of the IP stack to reject packets from the bridge. The idea is to forge the reject packets and inject them to the original port via br_deliver() which is now exported for that purpose. 5) Restrict nft_reject_bridge to bridge prerouting and input hooks. the original skbuff may cloned after prerouting when the bridge stack needs to flood it to several bridge ports, it is too late to reject the traffic. ==================== Signed-off-by: David S.

The validation assumes two possible configuration scenarios: 1) Use of nat from base chain that is not of nat type. Reject this configuration from the nft_*_init() path of the expression. 2) Use of nat from non-base chain. In this case, we have to wait until the non-base chain is referenced by at least one base chain via jump/goto. This is resolved from the nft_*_validate() path which is called from nf_tables_check_loops(). The user gets an -EOPNOTSUPP in both cases. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

This fixes a bug in many instances of firmware: Instead of lying about their age, these systems instead lie about the number of CPUs that they have. Before commit 35ce7f29a44a, this could result in huge numbers of useless rcuo kthreads being created. It appears that experience indicates that I should have told the people suffering from this problem to fix their broken firmware, but I instead produced what turned out to be a partial fix. The missing piece supplied by this commit makes sure that rcu_barrier() knows not to post callbacks for no-CBs CPUs that have not yet come online, because otherwise rcu_barrier() will hang on systems having firmware that lies about the number of CPUs. It is tempting to simply have rcu_barrier() refuse to post a callback on any no-CBs CPU that does not have an rcuo kthread. This unfortunately does not work because rcu_barrier() is required to wait for all pending callbacks. It is therefore required to wait even for those callbacks that cannot possibly be invoked. Even if doing so hangs the system. Given that posting a callback to a no-CBs CPU that does not yet have an rcuo kthread can hang rcu_barrier(), It is tempting to report an error in this case. Unfortunately, this will result in false positives at boot time, when it is perfectly legal to post callbacks to the boot CPU before the scheduler has started, in other words, before it is legal to invoke rcu_barrier(). So this commit instead has rcu_barrier() avoid posting callbacks to CPUs having neither rcuo kthread nor pending callbacks, and has it complain bitterly if it finds CPUs having no rcuo kthread but some pending callbacks. And when rcu_barrier() does find CPUs having no rcuo kthread but pending callbacks, as noted earlier, it has no choice but to hang indefinitely.

Unfortunately, when I submitted the patch (commit a9f18034) I left a comment in that claimed the bug was fixed in GCC 4.8.2+. This comment is inaccurate, and should be removed.
