Currently the hdmi-codec driver always registers both playback and capture capabilities but for most systems there's no actual capture capability, usually HDMI is transmit only. Provide platform data which allows the users to indicate what is supported so that we don't end up advertising things to userspace that we can't actually support. In order to avoid breaking existing users the flags in platform data are a bit awkward and specify what should be disabled rather than doing the perhaps more expected thing and defaulting to not supporting capture.

The flag that tells the event to call its triggers after reading the event is set for eprobes after the eprobe is enabled. This leads to a race where the eprobe may be triggered at the beginning of the event where the record information is NULL. The eprobe then dereferences the NULL record causing a NULL kernel pointer bug. Test for a NULL record to keep this from happening.

SRS cap is the hardware cap telling if the hardware IOMMU can support requests seeking supervisor privilege or not. SRE bit in scalable-mode PASID table entry is treated as Reserved(0) for implementation not supporting SRS cap. Checking SRS cap before setting SRE bit can avoid the non-recoverable fault of "Non-zero reserved field set in PASID Table Entry" caused by setting SRE bit while there is no SRS cap support. The fault messages look like below: DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Read NO_PASID] Request device [00:0d.0] fault addr 0x1154e1000 [fault reason 0x5a] SM: Non-zero reserved field set in PASID Table Entry Fixes: 6f7db75e ("iommu/vt-d: Add second level page table interface") Cc: stable@vger.kernel.org Signed-off-by: Tina Zhang <tina.zhang@intel.com> Link: https://lore.kernel.org/r/20221115070346.1112273-1-tina.zhang@intel.comSigned-off-by: Lu Baolu <baolu.lu@linux.intel.com> Link: https://lore.kernel.org/r/20221116051544.26540-3-baolu.lu@linux.intel.comSigned-off-by: Joerg Roedel <jroedel@suse.de>

The A/D bits are preseted for IOVA over first level(FL) usage for both kernel DMA (i.e, domain typs is IOMMU_DOMAIN_DMA) and user space DMA usage (i.e., domain type is IOMMU_DOMAIN_UNMANAGED). Presetting A bit in FL requires to preset the bit in every related paging entries, including the non-leaf ones. Otherwise, hardware may treat this as an error. For example, in a case of ECAP_REG.SMPWC==0, DMA faults might occur with below DMAR fault messages (wrapped for line length) dumped. DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Read NO_PASID] Request device [aa:00.0] fault addr 0x10c3a6000 [fault reason 0x90] SM: A/D bit update needed in first-level entry when set up in no snoop Fixes: 289b3b00 ("iommu/vt-d: Preset A/D bits for user space DMA usage") Cc: stable@vger.kernel.org Signed-off-by: Tina Zhang <tina.zhang@intel.com> Link: https://lore.kernel.org/r/20221113010324.1094483-1-tina.zhang@intel.comSigned-off-by: Lu Baolu <baolu.lu@linux.intel.com> Link: https://lore.kernel.org/r/20221116051544.26540-2-baolu.lu@linux.intel.comSigned-off-by: Joerg Roedel <jroedel@suse.de>

When we post a CQE we wake all ring pollers as it normally should be. However, if a CQE was generated by a multishot poll request targeting its own ring, it'll wake that request up, which will make it to post a new CQE, which will wake the request and so on until it exhausts all CQ entries. Don't allow multishot polling io_uring files but downgrade them to oneshots, which was always stated as a correct behaviour that the userspace should check for.

There was a problem that a user burned a dm-integrity image on CDROM and could not activate it because it had a non-empty journal. Fix this problem by flushing the journal (done by the previous commit) and clearing the journal (done by this commit). Once the journal is cleared, dm-integrity won't attempt to replay it on the next activation. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@kernel.org>

This commit flushes the journal on suspend. It is prerequisite for the next commit that enables activating dm integrity devices in read-only mode. Note that we deliberately didn't flush the journal on suspend, so that the journal replay code would be tested. However, the dm-integrity code is 5 years old now, so that journal replay is well-tested, and we can make this change now.

The 'no_sleep_enabled' should be decreased in error handling path in dm_bufio_client_create() when the DM_BUFIO_CLIENT_NO_SLEEP flag is set, otherwise static_branch_unlikely() will always return true even if no dm_bufio_client instances have DM_BUFIO_CLIENT_NO_SLEEP flag set.

__list_versions will first estimate the required space using the "dm_target_iterate(list_version_get_needed, &needed)" call and then will fill the space using the "dm_target_iterate(list_version_get_info, &iter_info)" call. Each of these calls locks the targets using the "down_read(&_lock)" and "up_read(&_lock)" calls, however between the first and second "dm_target_iterate" there is no lock held and the target modules can be loaded at this point, so the second "dm_target_iterate" call may need more space than what was the first "dm_target_iterate" returned. The code tries to handle this overflow (see the beginning of list_version_get_info), however this handling is incorrect. The code sets "param->data_size = param->data_start + needed" and "iter_info.end = (char *)vers+len" - "needed" is the size returned by the first dm_target_iterate call; "len" is the size of the buffer allocated by userspace. "len" may be greater than "needed"; in this case, the code will write up to "len" bytes into the buffer, however param->data_size is set to "needed", so it may write data past the param->data_size value. The ioctl interface copies only up to param->data_size into userspace, thus part of the result will be truncated. Fix this bug by setting "iter_info.end = (char *)vers + needed;" - this guarantees that the second "dm_target_iterate" call will write only up to the "needed" buffer and it will exit with "DM_BUFFER_FULL_FLAG" if it overflows the "needed" space - in this case, userspace will allocate a larger buffer and retry. Note that there is also a bug in list_version_get_needed - we need to add "strlen(tt->name) + 1" to the needed size, not "strlen(tt->name)".
