crypto: caam - add allocation failure handling in SPRINTFCAT macro

2014-06-07T20:25:39Z

commit 27c5fb7a84242b66bf1e0b2fe6bf40d19bcc5c04 upstream. GFP_ATOMIC memory allocation could fail. In this case, avoid NULL pointer dereference and notify user. Cc: Kim Phillips Signed-off-by: Horia Geanta Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: caam - Fixed the memory out of bound overwrite issue

2013-08-04T08:50:57Z

commit 9c23b7d3d6bda41e2a27375df705485523a96dc8 upstream. When kernel is compiled with CONFIG_SLUB_DEBUG=y and CRYPTO_MANAGER_DISABLE_TESTS=n, during kernel bootup, the kernel reports error given below. The root cause is that in function hash_digest_key(), for allocating descriptor, insufficient memory was being allocated. The required number of descriptor words apart from input and output pointers are 8 (instead of 6). ============================================================================= BUG dma-kmalloc-32 (Not tainted): Redzone overwritten ----------------------------------------------------------------------------- Disabling lock debugging due to kernel taint INFO: 0xdec5dec0-0xdec5dec3.

crypto: caam - fix job ring cleanup code

2013-04-25T13:09:07Z

The job ring init function creates a platform device for each job ring. While the job ring is shutdown, e.g. while caam module removal, its platform device was not being removed. This leads to failure while reinsertion and then removal of caam module second time. The following kernel crash dump appears when caam module is reinserted and then removed again. This patch fixes it. root@p4080ds:~# rmmod caam.ko Unable to handle kernel paging request for data at address 0x00000008 Faulting instruction address: 0xf94aca18 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=8 P4080 DS Modules linked in: caam(-) qoriq_dbg(O) [last unloaded: caam] NIP: f94aca18 LR: f94aca18 CTR: c029f950 REGS: eac47d60 TRAP: 0300 Tainted: G O (3.8.4-rt2) MSR: 00029002 CR: 22022484 XER: 20000000 DEAR: 00000008, ESR: 00000000 TASK = e49dfaf0[2110] 'rmmod' THREAD: eac46000 CPU: 1 GPR00: f94ad3f4 eac47e10 e49dfaf0 00000000 00000005 ea2ac210 ffffffff 00000000 GPR08: c286de68 e4977ce0 c029b1c0 00000001 c029f950 10029738 00000000 100e0000 GPR16: 00000000 10023d00 1000cbdc 1000cb8c 1000cbb8 00000000 c07dfecc 00000000 GPR24: c07e0000 00000000 1000cbd8 f94e0000 ffffffff 00000000 ea53cd40 00000000 NIP [f94aca18] caam_reset_hw_jr+0x18/0x1c0 [caam] LR [f94aca18] caam_reset_hw_jr+0x18/0x1c0 [caam] Call Trace: [eac47e10] [eac47e30] 0xeac47e30 (unreliable) [eac47e20] [f94ad3f4] caam_jr_shutdown+0x34/0x220 [caam] [eac47e60] [f94ac0e4] caam_remove+0x54/0xb0 [caam] [eac47e80] [c029fb38] __device_release_driver+0x68/0x120 [eac47e90] [c02a05c8] driver_detach+0xd8/0xe0 [eac47eb0] [c029f8e0] bus_remove_driver+0xa0/0x110 [eac47ed0] [c00768e4] sys_delete_module+0x144/0x270 [eac47f40] [c000e2f0] ret_from_syscall+0x0/0x3c Signed-off-by: Vakul Garg Signed-off-by: Bharat Bhushan Reviewed-by: Horia Geanta Signed-off-by: Herbert Xu

crypto: caam - set RDB bit in security configuration register

2013-03-22T10:13:54Z

This change is required for post SEC-5.0 devices which have RNG4. Setting RDB in security configuration register allows CAAM to use the "Random Data Buffer" to be filled by a single request. The Random Data Buffer is large enough for ten packets to get their IVs from a single request. If the Random Data Buffer is not enabled, then each IV causes a separate request, and RNG4 hardware cannot keep up resulting in lower IPSEC throughput if random IVs are used.
