2019-05-03crypto: crypto4xx - fix cfb and ofb "overran dst buffer" issuesChristian Lamparter1-10/+21
Currently, crypto4xx CFB and OFB AES ciphers are failing testmgr's test vectors. |cfb-aes-ppc4xx encryption overran dst buffer on test vector 3, cfg="in-place" |ofb-aes-ppc4xx encryption overran dst buffer on test vector 1, cfg="in-place" This is because of a very subtile "bug" in the hardware that gets indirectly mentioned in 18.1.3.5 Encryption/Decryption of the hardware spec: the OFB and CFB modes for AES are listed there as operation modes for >>> "Block ciphers" <<<. Which kind of makes sense, but we would like them to be considered as stream ciphers just like the CTR mode. To workaround this issue and stop the hardware from causing "overran dst buffer" on crypttexts that are not a multiple of 16 (AES_BLOCK_SIZE), we force the driver to use the scatter buffers as the go-between. As a bonus this patch also kills redundant pd_uinfo->num_gd and pd_uinfo->num_sd setters since the value has already been set before.

2019-05-03crypto: crypto4xx - fix ctr-aes missing output IVChristian Lamparter1-3/+9
Commit 8efd972ef96a ("crypto: testmgr - support checking skcipher output IV") caused the crypto4xx driver to produce the following error: | ctr-aes-ppc4xx encryption test failed (wrong output IV) | on test vector 0, cfg="in-place" This patch fixes this by reworking the crypto4xx_setkey_aes() function to: - not save the iv for ECB (as per 18.2.38 CRYP0_SA_CMD_0: "This bit mut be cleared for DES ECB mode or AES ECB mode, when no IV is used.") - instruct the hardware to save the generated IV for all other modes of operations that have IV and then supply it back to the callee in pretty much the same way as we do it for cbc-aes already. - make it clear that the DIR_(IN|OUT)BOUND is the important bit that tells the hardware to encrypt or decrypt the data. (this is cosmetic - but it hopefully prevents me from getting confused again). - don't load any bogus hash when we don't use any hash operation to begin with.

This is an issue for SoCs without the PIT (sams70, samv70 and samv71 families) as they simply currently can't boot. Get rid of the atmel_tclib dependency and probe everything on our own using the correct device tree binding.

2019-05-02RDMA/umem: Handle page combining avoidance correctly in ib_umem_add_sg_table()Shiraz Saleem1-6/+10
The flag update_cur_sg tracks whether contiguous pages from a new set of page_list pages can be merged into the SGE passed into ib_umem_add_sg_table(). If this flag is true, but the total segment length exceeds the max_seg_size supported by HW, we avoid combining to this SGE and move to a new SGE (x) and merge 'len' pages to it. However, if i < npages, the next iteration can incorrectly merge 'len' contiguous pages into x instead of into a new SGE since update_cur_sg is still true. Reset update_cur_sg to false always after the check to merge pages into the first SGE passed in to ib_umem_add_sg_table(). Also, prevent a new SGE's segment length from ever exceeding HW max_seg_sz. There is a crash on hfi1 as result of this where-in max_seg_sz is defaulting to 64K. Due to above bug, unfolding SGE's in __ib_umem_release points to a bad page ptr.

Pull networking fixes from David Miller: 1) Out of bounds access in xfrm IPSEC policy unlink, from Yue Haibing. 2) Missing length check for esp4 UDP encap, from Sabrina Dubroca. 3) Fix byte order of RX STBC access in mac80211, from Johannes Berg. 4) Inifnite loop in bpftool map create, from Alban Crequy. 5) Register mark fix in ebpf verifier after pkt/null checks, from Paul Chaignon. 6) Properly use rcu_dereference_sk_user_data in L2TP code, from Eric Dumazet. 7) Buffer overrun in marvell phy driver, from Andrew Lunn. 8) Several crash and statistics handling fixes to bnxt_en driver, from Michael Chan and Vasundhara Volam. 9) Several fixes to the TLS layer from Jakub Kicinski (copying negative amounts of data in reencrypt, reencrypt frag copying, blind nskb->sk NULL deref, etc). 10) Several UDP GRO fixes, from Paolo Abeni and Eric Dumazet. 11) PID/UID checks on ipv6 flow labels are inverted, from Willem de Bruijn. 12) Use after free in l2tp, from Eric Dumazet. 13) IPV6 route destroy races, also from Eric Dumazet. 14) SCTP state machine can erroneously run recursively, fix from Xin Long. 15) Adjust AF_PACKET msg_name length checks, add padding bytes if necessary. From Willem de Bruijn. 16) Preserve skb_iif, so that forwarded packets have consistent values even if fragmentation is involved.
