2019-11-06net: silence data-races on sk_backlog.tailEric Dumazet1-5/+5

2019-11-01inet: stop leaking jiffies on the wireEric Dumazet1-1/+1
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.

2019-09-20crypto: hisilicon - Fix double free in sec_free_hw_sgl()Yunfeng Ye1-6/+7
There are two problems in sec_free_hw_sgl(): First, when sgl_current->next is valid, @hw_sgl will be freed in the first loop, but it free again after the loop. Second, sgl_current and sgl_current->next_sgl is not match when dma_pool_free() is invoked, the third parameter should be the dma address of sgl_current, but sgl_current->next_sgl is the dma address of next chain, so use sgl_current->next_sgl is wrong.

2019-09-09crypto: caam - dispose of IRQ mapping only after IRQ is freedAndrey Smirnov1-4/+10
With IRQ requesting being managed by devres we need to make sure that we dispose of IRQ mapping after and not before it is free'd (otherwise we'll end up with a warning from the kernel). To achieve that simply convert IRQ mapping to rely on devres as well.

2019-09-09crypto: caam - make sure clocks are enabled firstAndrey Smirnov1-15/+15
In order to access IP block's registers we need to enable appropriate clocks first, otherwise we are risking hanging the CPU. The problem becomes very apparent when trying to use CAAM driver built as a kernel module. In that case caam_probe() gets called after clk_disable_unused() which means all of the necessary clocks are guaranteed to be disabled. Coincidentally, this change also fixes iomap leak introduced by early return (instead of "goto iounmap_ctrl") in commit 41fc54afae70 ("crypto: caam - simplfy clock initialization") Tested on ZII i.MX6Q+ RDU2 Fixes: 176435ad2ac7 ("crypto: caam - defer probing until QMan is available") Fixes: 41fc54afae70 ("crypto: caam - simplfy clock initialization") Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Cc: Chris Healy <cphealy@gmail.com> Cc: Lucas Stach <l.stach@pengutronix.de> Cc: Horia Geantă <horia.geanta@nxp.com> Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Iuliana Prodan <iuliana.prodan@nxp.com> Cc: linux-crypto@vger.kernel.org Cc: linux-kernel@vger.kernel.org Tested-by: Horia Geantă <horia.geanta@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
