2016-03-23PKCS#7: pkcs7_validate_trust(): initialize the _trusted output argumentNicolai Stange1-0/+2
Despite what the DocBook comment to pkcs7_validate_trust() says, the *_trusted argument is never set to false. pkcs7_validate_trust() only positively sets *_trusted upon encountering a trusted PKCS#7 SignedInfo block. This is quite unfortunate since its callers, system_verify_data() for example, depend on pkcs7_validate_trust() clearing *_trusted on non-trust. Indeed, UBSAN splats when attempting to load the uninitialized local variable 'trusted' from system_verify_data() in pkcs7_validate_trust(): UBSAN: Undefined behaviour in crypto/asymmetric_keys/pkcs7_trust.c:194:14 load of value 82 is not a valid value for type '_Bool' [...] Call Trace: [<ffffffff818c4d35>] dump_stack+0xbc/0x117 [<ffffffff818c4c79>] ? _atomic_dec_and_lock+0x169/0x169 [<ffffffff8194113b>] ubsan_epilogue+0xd/0x4e [<ffffffff819419fa>] __ubsan_handle_load_invalid_value+0x111/0x158 [<ffffffff819418e9>] ? val_to_string.constprop.12+0xcf/0xcf [<ffffffff818334a4>] ? x509_request_asymmetric_key+0x114/0x370 [<ffffffff814b83f0>] ? kfree+0x220/0x370 [<ffffffff818312c2>] ? public_key_verify_signature_2+0x32/0x50 [<ffffffff81835e04>] pkcs7_validate_trust+0x524/0x5f0 [<ffffffff813c391a>] system_verify_data+0xca/0x170 [<ffffffff813c3850>] ? top_trace_array+0x9b/0x9b [<ffffffff81510b29>] ? __vfs_read+0x279/0x3d0 [<ffffffff8129372f>] mod_verify_sig+0x1ff/0x290 [...] The implication is that pkcs7_validate_trust() effectively grants trust when it really shouldn't have.

2016-03-23drm/i915: Wait for vblank in i9xx_disable_crtc() for gen 2 onlyAnder Conselvan de Oliveira1-3/+2
The wait for other gens was added in commit 564ed191f5d8 ("drm/i915: gmch: fix stuck primary plane due to memory self-refresh mode") since that's necessary when disabling cxsr. However, cxsr disabling was later moved to intel_pre_disable_primary() in commit 87d4300a7dbc ("drm/i915: Move intel_(pre_disable/post_enable)_primary to intel_display.c, and use it there.") and that function got its own vblank wait for cxsr in commit 262cd2e154c2 ("drm/i915: CHV DDR DVFS support and another watermark rewrite"). So remove the extra vblank wait from i9xx_crtc_distable().

2016-03-23drm/i915: Fix use after free when printing load failureMika Kuoppala1-2/+2
Commit d15d7538c6d2 ("drm/i915: Tune down init error message due to failure injection") added i915_load_error message to failure path on device initialization. The message is printed after the device is freed. And as the message printing helper uses the device structure, this leads to use after free. Spotted by Kasan.

2016-03-23ALSA: timer: fix gparams ioctl compatibility for different architecturesTakashi Sakamoto2-8/+42
'struct snd_timer_gparams' includes some members with 'unsigned long', therefore its size differs depending on data models of architecture. As a result, x86/x32 applications fail to execute ioctl(2) with SNDRV_TIMER_GPARAMS command on x86_64 machine. This commit fixes this bug by adding a pair of structure and ioctl command for the compatibility. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
