Toradex Carrier boards use the ST M41T0 RTC (not M41T00). The RTC is almost the same, but the M41T0 needs some special handling in case the oscillator fails.

The m41t0 variant is very similar to the already supported m41t00 variant, with the notable exception of the oscillator fail bit. The data sheet notes: If the oscillator fail (OF) bit is internally set to a '1,' this indicates that the oscillator has either stopped, or was stopped for some period of time and can be used to judge the validity of the clock and date data. The bit will get cleared with a regular write of the system time, so no changes are needed to clear it.

2017-06-09video: tegra: nvmap: Fix NULL pointer dereferenceSri Krishna chowdary
Consider the following case: 1. NVMAP_IOC_CREATE on IOVMM gives a valid fd to user space 2. user space does not call NVMAP_IOC_ALLOC. 3. user space calls a client driver IOCTL which calls dma_buf_map_attachment 4. call to dma_buf_map_attachment propagates till__nvmap_sg_table which has heap_pgalloc as true and tries to access pages[] which has all NULL. 5. Similarly, a dma_buf_kmap() can result in __nvmap_kmap() being called which again results in NULL dereference if pages[] is accessed. A valid __nvmap_sg_table should occur only when h->alloc is true. So, add check for it. bug 1838597 bug 1883708 Change-Id: I400d9d8a94ff1003db207fc9c252b9256d796f60 Signed-off-by: Sri Krishna chowdary <schowdary@nvidia.com> Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> (cherry picked from commit 8244d104b7635cb0b26b651b6851498b9a84d7d6) Reviewed-on: http://git-master/r/1489579 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Bibek Basu <bbasu@nvidia.com> Tested-by: Bibek Basu <bbasu@nvidia.com>

2017-05-16media: tegra: camera: sanity-check ioctl parameterGreg Hackmann
Several places in the camera stack can hit integer overflows or cause bad allocations if userspace passes in a bogus sizeofvalue parameter. Protect against this by using appropriately-sized integer types, adding range checks, replacing array-allocation calls with kcalloc(), and checking for allocations returning ZERO_SIZE_PTR. For one specific ioctl (PCLLK_IOCTL_UPDATE) sizeofvalue = 0 is fine, since when that happens the subdrivers won't actually touch the returned allocation. In fact the existing userspace camera driver makes calls like these and expects them to succeed! Handle this special case by adding a __camera_get_params variant that optionally treats zero-sized inputs as valid.

2017-05-05video: tegra: nvmap: Check if handle holds a buffer before mapSri Krishna chowdary
Consider the following case: 1. NVMAP_IOC_CREATE gives a valid fd to user space 2. user space calls NVMAP_IOC_ALLOC and it fails. So, all of the handle's allocation fields are zero. 3. Subsequent dma_buf_vmap, mmap on fd leads to __nvmap_mmap call. 4. handle is valid but h->alloc, h->carveout, h->heap_pgalloc, h->vaddr all are 0. 5. We check for h->heap_pgalloc which is false, so proceed and dereference h->carveout leading to NULL pointer exception. A valid __nvmap_mmap should occur only when h->alloc is true. So, add check for it. bug 1837468 Change-Id: I9be9d94f9b74c25b9b588fb1a16a74e96161ceda Signed-off-by: Sri Krishna chowdary <schowdary@nvidia.com> Reviewed-on: http://git-master/r/1253236 (cherry picked from commit c5da78cf3d0c19f1e04501a4b3f64a5acacd0ff3) Reviewed-on: http://git-master/r/1312264 GVS: Gerrit_Virtual_Submit Reviewed-by: Bibek Basu <bbasu@nvidia.com> Tested-by: Bibek Basu <bbasu@nvidia.com>

2017-04-26dccp: fix freeing skb too early for IPV6_RECVPKTINFOSandipan Patra
In the current DCCP implementation an skb for a DCCP_PKT_REQUEST packet is forcibly freed via __kfree_skb in dccp_rcv_state_process if dccp_v6_conn_request successfully returns. However, if IPV6_RECVPKTINFO is set on a socket, the address of the skb is saved to ireq->pktopts and the ref count for skb is incremented in dccp_v6_conn_request, so skb is still in use. Nevertheless, it gets freed in dccp_rcv_state_process. Fix by calling consume_skb instead of doing goto discard and therefore calling __kfree_skb. Similar fixes for TCP: fb7e2399ec17f1004c0e0ccfd17439f8759ede01 [TCP]: skb is unexpectedly freed. 0aea76d35c9651d55bbaf746e7914e5f9ae5a25d tcp: SYN packets are now simply consumed Signed-off-by: Andrey Konovalov <andreyknvl@google.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
