Crypto/chcr: fix for ccm(aes) failed test

2020-06-22T07:31:02+00:00

[ Upstream commit 10b0c75d7bc19606fa9a62c8ab9180e95c0e0385 ] The ccm(aes) test fails when req->assoclen > ~240bytes. The problem is the value assigned to auth_offset is wrong. As auth_offset is unsigned char, it can take max value as 255. So fix it by making it unsigned int. Signed-off-by: Ayush Sawal Signed-off-by: Devulapally Shiva Krishna Signed-off-by: David S.

Crypto: chelsio - Fixes a hang issue during driver registration

2020-05-02T06:49:00+00:00

commit ad59ddd02de26271b89564962e74d689f1a30b49 upstream. This issue occurs only when multiadapters are present. Hang happens because assign_chcr_device returns u_ctx pointer of adapter which is not yet initialized as for this adapter cxgb_up is not been called yet. The last_dev pointer is used to determine u_ctx pointer and it is initialized two times in chcr_uld_add in chcr_dev_add respectively. The fix here is don't initialize the last_dev pointer during chcr_uld_add. Only assign to value to it when the adapter's initialization is completed i.e in chcr_dev_add.

crypto: chelsio - fix writing tfm flags to wrong place

2020-02-01T09:34:36+00:00

commit bd56cea012fc2d6381e8cd3209510ce09f9de8c9 upstream. The chelsio crypto driver is casting 'struct crypto_aead' directly to 'struct crypto_tfm', which is incorrect because the crypto_tfm isn't the first field of 'struct crypto_aead'. Consequently, the calls to crypto_tfm_set_flags() are modifying some other field in the struct. Also, the driver is setting CRYPTO_TFM_RES_BAD_KEY_LEN in ->setauthsize(), not just in ->setkey(). This is incorrect since this flag is for bad key lengths, not for bad authentication tag lengths. Fix these bugs by removing the broken crypto_tfm_set_flags() calls from ->setauthsize() and by fixing them in ->setkey().

inet: stop leaking jiffies on the wire

2019-11-01T21:57:52+00:00

Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical.

net: use skb_queue_empty_lockless() in busy poll contexts

2019-10-28T20:33:41+00:00

Busy polling usually runs without locks. Let's use skb_queue_empty_lockless() instead of skb_queue_empty() Also uses READ_ONCE() in __skb_try_recv_datagram() to address a similar potential problem. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

mm: introduce page_size()

2019-09-24T22:54:08+00:00

Patch series "Make working with compound pages easier", v2. These three patches add three helpers and convert the appropriate places to use them. This patch (of 3): It's unnecessarily hard to find out the size of a potentially huge page. Replace 'PAGE_SIZE << compound_order(page)' with page_size(page).
