* digsig: make crypto builtin if digsig selected as builtinDmitry Kasatkin2014-07-171-1/+2
| | | | | | | | | When SIGNATURE=y but depends on CRYPTO=m, it selects MPILIB as module producing build break. This patch makes digsig to select crypto for correcting dependency. Signed-off-by: Dmitry Kasatkin <d.kasatkin@samsung.com> Signed-off-by: David Howells <dhowells@redhat.com>
* lz4: add overrun checks to lz4_uncompress_unknownoutputsize()Greg Kroah-Hartman2014-07-031-1/+5
| | | | | | | | | | | | | | | | Jan points out that I forgot to make the needed fixes to the lz4_uncompress_unknownoutputsize() function to mirror the changes done in lz4_decompress() with regards to potential pointer overflows. The only in-kernel user of this function is the zram code, which only takes data from a valid compressed buffer that it made itself, so it's not a big issue. But due to external kernel modules using this function, it's better to be safe here. Reported-by: Jan Beulich <JBeulich@suse.com> Cc: "Don A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is one other possible overrun in the lz4 code as implemented by Linux at this point in time (which differs from the upstream lz4 codebase, but will get synced at in a future kernel release.) As pointed out by Don, we also need to check the overflow in the data itself. While we are at it, replace the odd error return value with just a "simple" -1 value as the return value is never used for anything other than a basic "did this work or not" check.

While checking virtual addresses against NULL is a legitimate thing to catch invalid entries, checking physical ones against zero isn't: There's no guarantee that PFN 0 is reserved on a particular platform. Since it is unclear whether the check in swiotlb_tbl_unmap_single() is actually needed, retain it but check against a guaranteed invalid physical address. This requires setting up the array in a suitable fashion. And since the original code failed to invalidate array entries when regions get unmapped, this is being fixed at once along with adding a similar check to swiotlb_tbl_sync_single(). Obviously the less intrusive change would be to simply drop the check in swiotlb_tbl_unmap_single().

This is actually a valid insn ("ld #0"), so any filter with includes "BPF_STMT(BPF_LD | BPF_IMM, 0)" fails (its length is cut short). We are changing probe_filter_length() so as to start from the end, and declare the end of the filter as the first instruction which is not {0, *, *, 0}. This solution produces a simpler patch than the alternative of using an explicit end-of-filter mark. It is technically incorrect if your filter ends up with "ld #0", but that should not happen anyway. We also add a new test (LD_IMM_0) that includes ld #0 (does not work without this patch).

We have: - STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and thus relies on the HCI stack. This submission provides support for tag redaer/writer mode (including Type 5) and device tree bindings. - PM runtime support and a bunch of bug fixes for TI's trf7970a. - Device tree support for NXP's pn544. Legacy platform data support is obviously kept intact. - NFC Tag type 4B support to the NFC Digital stack. - SOCK_RAW type support to the raw NFC socket, and allow NCI sniffing from that. This can be extended to report HCI frames and also proprietarry ones like e.g. the pn533 ones." For the iwlwifi bits, Emmanuel says: "Eran continues to work on new devices, Eyal is still digging in the rate control stuff, and Johannes added new functionality to the debug system we have in place now along with a few cleanups he made on the way. That's pretty much it." and; "Avri continues to work on the power code and Eran is improving the NVM handling as a preparations for new devices on which he works with Liad. Luca cleans up a bit the code while working on CSA. I have the regular BT Coex stuff and a small lockdep fix. Johannes has his regular amount of clean ups and improvements, the main one is the ability to leave 2 chains open to improve diversity and hence the throughput in high attenuation scenarios." and; "The regular amount of housekeeping here. I merged iwlwifi-fixes.git to be able to add the patch you didn't want in wireless.git at that stage of the -rc cycle. Luca has a few preparations for CSA implementation and also what seems to be a bugfix for P2P but hasn't caused issues we could notice."

The last two tests are expected to fail by the BPF checker already, as in classic BPF only K or A are allowed to be returned. Thus, there are now 52 test cases for BPF.

As a result, due to __user annotation in sock_fprog, sparse triggers false positives (incorrect type in assignment [different address space]) when filters are set up before passing them to sk_unattached_filter_create(). Therefore, let sk_unattached_filter_create() API use sock_fprog_kern to overcome this issue.

The condition is that the unallocated ID shares the same lowest idr layer with the existing ID, but the idr slot would be different if the unallocated ID were to be allocated. In this case the matching idr slot for the unallocated_id is NULL, causing @bitmap to be NULL which the function dereferences without checking crashing the kernel. See the test code: static void test3(void) { int id; DEFINE_IDA(test_ida); printk(KERN_INFO "Start test3\n"); if (ida_pre_get(&test_ida, GFP_KERNEL) < 0) return; if (ida_get_new(&test_ida, &id) < 0) return; ida_remove(&test_ida, 4000); /* bug: null deference here */ printk(KERN_INFO "End of test3\n"); } It happens only when the caller tries to free an unallocated ID which is the caller's fault. It is not a bug. But it is better to add the proper check and complain rather than crashing the kernel.

The following test code shows it fails to replace the value for id=((1<<27)+42): static void test5(void) { int id; DEFINE_IDR(test_idr); #define TEST5_START ((1<<27)+42) /* use the highest layer */ printk(KERN_INFO "Start test5\n"); id = idr_alloc(&test_idr, (void *)1, TEST5_START, 0, GFP_KERNEL); BUG_ON(id != TEST5_START); TEST_BUG_ON(idr_replace(&test_idr, (void *)2, TEST5_START) != (void *)1); idr_destroy(&test_idr); printk(KERN_INFO "End of test5\n"); } Fix the bug by using idr_max() which correctly takes into account the maximum allowed shift. sub_alloc() shares the same problem and may incorrectly fail with -EAGAIN; however, this bug doesn't affect correct operation because idr_get_empty_slot(), which already uses idr_max(), retries with the increased @id in such cases.
