crypto: prefix module autoloading with "crypto-"

2014-11-24T14:43:57Z

This prefixes all crypto module loading with "crypto-" so we never run the risk of exposing module auto-loading to userspace via a crypto API, as demonstrated by Mathias Krause: https://lkml.org/lkml/2013/3/4/70 Signed-off-by: Kees Cook Signed-off-by: Herbert Xu

crypto: lzo - use kvfree() helper

2014-06-25T13:51:53Z

kvfree() helper is now available, use it instead of open code it. Signed-off-by: Eric Dumazet Signed-off-by: Herbert Xu

crypto: lzo - try kmalloc() before vmalloc()

2014-06-20T13:26:05Z

zswap allocates one LZO context per online cpu. Using vmalloc() for small (16KB) memory areas has drawback of slowing down /proc/vmallocinfo and /proc/meminfo reads, TLB pressure and poor NUMA locality, as default NUMA policy at boot time is to interleave pages : edumazet:~# grep lzo /proc/vmallocinfo | head -4 0xffffc90006062000-0xffffc90006067000 20480 lzo_init+0x1b/0x30 pages=4 vmalloc N0=2 N1=2 0xffffc90006067000-0xffffc9000606c000 20480 lzo_init+0x1b/0x30 pages=4 vmalloc N0=2 N1=2 0xffffc9000606c000-0xffffc90006071000 20480 lzo_init+0x1b/0x30 pages=4 vmalloc N0=2 N1=2 0xffffc90006071000-0xffffc90006076000 20480 lzo_init+0x1b/0x30 pages=4 vmalloc N0=2 N1=2 This patch tries a regular kmalloc() and fallback to vmalloc in case memory is too fragmented.

crypto: cleanup - remove unneeded crypto_alg.cra_list initializations

2012-08-01T09:47:27Z

Initialization of cra_list is currently mixed, most ciphers initialize this field and most shashes do not. Initialization however is not needed at all since cra_list is initialized/overwritten in __crypto_register_alg() with list_add(). Therefore perform cleanup to remove all unneeded initializations of this field in 'crypto/'. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu
