crypto: crypto4xx - fix crypto4xx_build_pdr, crypto4xx_build_sdr leak

2018-07-22T12:25:52+00:00

commit 5d59ad6eea82ef8df92b4109615a0dde9d8093e9 upstream. If one of the later memory allocations in rypto4xx_build_pdr() fails: dev->pdr (and/or) dev->pdr_uinfo wouldn't be freed. crypto4xx_build_sdr() has the same issue with dev->sdr.

crypto: crypto4xx - remove bad list_del

2018-07-22T12:25:52+00:00

commit a728a196d253530f17da5c86dc7dfbe58c5f7094 upstream. alg entries are only added to the list, after the registration was successful. If the registration failed, it was never added to the list in the first place.

crypto: crypto4xx - increase context and scatter ring buffer elements

2017-12-25T13:22:14+00:00

[ Upstream commit 778f81d6cdb7d25360f082ac0384d5103f04eca5 ] If crypto4xx is used in conjunction with dm-crypt, the available ring buffer elements are not enough to handle the load properly. On an aes-cbc-essiv:sha256 encrypted swap partition the read performance is abyssal: (tested with hdparm -t) /dev/mapper/swap_crypt: Timing buffered disk reads: 14 MB in 3.68 seconds = 3.81 MB/sec The patch increases both PPC4XX_NUM_SD and PPC4XX_NUM_PD to 256. This improves the performance considerably: /dev/mapper/swap_crypt: Timing buffered disk reads: 104 MB in 3.03 seconds = 34.31 MB/sec Furthermore, PPC4XX_LAST_SD, PPC4XX_LAST_GD and PPC4XX_LAST_PD can be easily calculated from their respective PPC4XX_NUM_* constant.

crypto: amcc - replace get_sg_count by sg_nents_for_len

2015-09-21T15:05:53+00:00

The get_sg_count function of amcc is the same as sg_nents_for_len from lib/scatterlist.c Signed-off-by: LABBE Corentin Signed-off-by: Herbert Xu

crypto: amcc - Fix module autoload for OF platform driver

2015-09-21T14:00:36+00:00

This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Luis de Bethencourt Signed-off-by: Herbert Xu

crypto: amcc - Do a NULL check for pointer

2015-08-17T08:53:55+00:00

Compare pointer-typed values to NULL rather than 0. The semantic patch that makes this change is available in scripts/coccinelle/null/badzero.cocci Signed-off-by: Fabio Estevam Signed-off-by: Herbert Xu

crypto: amcc - remove incorrect init/exit markups

2015-03-11T14:11:07+00:00

Even if bus is not hot-pluggable, the devices can be bound and unbound from the driver via sysfs, so we should not be using __init/__exit annotations on probe() and remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Signed-off-by: Dmitry Torokhov Signed-off-by: Herbert Xu

crypto: amcc - Remove unused function

2015-01-05T10:36:07+00:00

Remove the function get_dynamic_sa_offset_iv_field() that is not used anywhere. This was partially found by using a static code analysis program called cppcheck. Signed-off-by: Rickard Strandqvist Signed-off-by: Herbert Xu

crypto: amcc: drop owner assignment from platform_drivers

2014-10-20T14:20:25+00:00

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang
