commit ac37e251 upstream. dst_orig should be released on error. Function like __xfrm_route_forward() expects that behavior. Since a recent commit, xfrm_lookup() may also be called by xfrm_lookup_route(), which expects the opposite. Let's introduce a new flag (XFRM_LOOKUP_KEEP_DST_REF) to tell what should be done in case of error. Fixes: f92ee619("xfrm: Generate blackhole routes only from route lookup functions") Signed-off-by:

commit f104765b upstream. If hardware doesn't support DecodeAssist - a feature that provides more information about the intercept in the VMCB, KVM decodes the instruction and then updates the next_rip vmcb control field. However, NRIP support itself depends on cpuid Fn8000_000A_EDX[NRIPS]. Since skip_emulated_instruction() doesn't verify nrip support before accepting control.next_rip as valid, avoid writing this field if support isn't present. Signed-off-by:

commit 5f5bc6b1 upstream. Replacing a xattr consists of doing a lookup for its existing value, delete the current value from the respective leaf, release the search path and then finally insert the new value. This leaves a time window where readers (getxattr, listxattrs) won't see any value for the xattr. Xattrs are used to store ACLs, so this has security implications. This change also fixes 2 other existing issues which were: *) Deleting the old xattr value without verifying first if the new xattr will fit in the existing leaf item (in case multiple xattrs are packed in the same item due to name hash collision); *) Returning -EEXIST when the flag XATTR_CREATE is given and the xattr doesn't exist but we have have an existing item that packs muliple xattrs with the same name hash as the input xattr. In this case we should return ENOSPC. A test case for xfstests follows soon. Thanks to Alexandre Oliva for reporting the non-atomicity of the xattr replace implementation. Reported-by:

commit c80e5c0c upstream. On x86-64, __copy_instruction() always returns 0 (error) if the instruction uses %rip-relative addressing. This is because kernel_insn_init() is called the second time for 'insn' instance in such cases and sets all its fields to 0. Because of this, trying to place a kprobe on such instruction will fail, register_kprobe() will return -EINVAL. This patch fixes the problem. Signed-off-by:

pipe_iov_copy_{from,to}_user() may be tried twice with the same iovec, the first time atomically and the second time not. The second attempt needs to continue from the iovec position, pipe buffer offset and remaining length where the first attempt failed, but currently the pipe buffer offset and remaining length are reset. This will corrupt the piped data (possibly also leading to an information leak between processes) and may also corrupt kernel memory. This was fixed upstream by commits f0d1bec9 ("new helper: copy_page_from_iter()") and 637b58c2 ("switch pipe_read() to copy_page_to_iter()"), but those aren't suitable for stable. This fix for older kernel versions was made by Seth Jennings for RHEL and I have extracted it from their update.

James Smart authored
commit 27f344eb upstream. Add a memory barrier to ensure the valid bit is read before any of the cqe payload is read. This fixes an issue seen on Power where the cqe payload was getting loaded before the valid bit. When this occurred, we saw an iotag out of range error when a command completed, but since the iotag looked invalid the command didn't get completed to scsi core. Later we hit the command timeout, attempted to abort the command, then waited for the aborted command to get returned. Since the adapter already returned the command, we timeout waiting, and end up escalating EEH all the way to host reset. This patch fixes this issue. Signed-off-by:

commit c4d69da1 upstream. Running igt, I was encountering the invalid TLB bug on my 845g, despite that it was using the CS workaround. Examining the w/a buffer in the error state, showed that the copy from the user batch into the workaround itself was suffering from the invalid TLB bug (the first cacheline was broken with the first two words reversed). Time to try a fresh approach. This extends the workaround to write into each page of our scratch buffer in order to overflow the TLB and evict the invalid entries. This could be refined to only do so after we update the GTT, but for simplicity, we do it before each batch. I suspect this supersedes our current workaround, but for safety keep doing both. V2: The magic number shall be 2. This doesn't conclusively prove that it is the mythical TLB bug we've been trying to workaround for so long, that it requires touching a number of pages to prevent the corruption indicates to me that it is TLB related, but the corruption (the reversed cacheline) is more subtle than a TLB bug, where we would expect it to read the wrong page entirely. Oh well, it prevents a reliable hang for me and so probably for others as well. Signed-off-by:

commit 7e7e8fe6 upstream. The pcc-cpufreq driver is not automatically loaded on systems where the platform's power management setting requires this driver. Instead, on those systems no CPU frequency driver is registered and active. Make the autoloading matching criteria for loading the pcc-cpufreq driver the same as done in acpi-cpufreq by commit c655affb ("ACPI / cpufreq: Add ACPI processor device IDs to acpi-cpufreq"). x86 CPU frequency drivers are now typically autoloaded by specifying MODULE_DEVICE_TABLE entries and x86cpu model specific matching. But pcc-cpufreq was omitted when acpi-cpufreq and other drivers were changed to use this approach. Both acpi-cpufreq and pcc-cpufreq depend on a distinct and mutually exclusive set of ACPI methods which are not directly tied to specific processor model numbers. Both of these drivers have init routines which look for their required ACPI methods. As a result, only the appropriate driver registers as the cpu frequency driver and the other one ends up being unloaded. Tested on various systems where acpi-cpufreq, intel_pstate, and pcc-cpufreq are the expected cpu frequency drivers. Signed-off-by:

commit 93fb9127 upstream. This patch fixes an issue that sometimes this controller is not able to complete the Control write status stage. This driver should enable DCPCTR.CCPL and PID_BUF to complete the status stage. However, if this driver detects the ctrl_stage interruption first before the control write data is received, this driver will clear the PID_BUF wrongly in the usbhsf_pio_try_pop(). To avoid this issue, this patch doesn't clear the PID_BUF in the usbhsf_pio_try_pop(). (Since also the privious code doesn't disable the PID_BUF after a control transfer was finished, this patch doesn't have any side efforts.) Signed-off-by:

commit e73d42f1 upstream. This patch fixes an issue for control write. When usbhsf_prepare_pop() is called after this driver called a gadget setup function, this controller doesn't receive the control write data. So, this patch adds a code to clear the fifo for control write in usbhsf_prepare_pop(). Signed-off-by:
