There is no point in warning when there is no ucode available for a specific CPU revision. Currently the container-file, which provides the AMD ucode patches for OS load, contains only a few ucode patches. It's already clearly indicated by the printed patch_level whenever new ucode was available and an update happened. So the warning message is of no help but rather annoying on systems with many CPUs.

This also implies that corresponding log messages, e.g. platform microcode: firmware: requesting amd-ucode/microcode_amd.bin show up only once on module load and not when ucode is updated for each CPU.

This patch fixes two issues in the procfs stack information on x86-64 linux. The 32 bit loader compat_do_execve did not store stack start. (this was figured out by Alexey Dobriyan). The stack information on a x64_64 kernel always shows 0 kbyte stack usage, because of a missing implementation of the KSTK_ESP macro which always returned -1. The new implementation now returns the right value.

When PAE is enabled in the kernel configuration the size of phys_addr_t differs from the size of a void pointer. The gcc prints a warning about that in dma-debug code.

Restoring %ebp after the call to audit_syscall_exit() is not only unnecessary (because the register didn't get clobbered), but in the sysenter case wasn't even doing the right thing: It loaded %ebp from a location below the top of stack (RBP < ARGOFFSET), i.e. arbitrary kernel data got passed back to user mode in the register.

Non-PAE 32-bit dump kernels may wrap an address around 4G and poke unwanted space. ptes there are 32-bit long, and since pfn << PAGE_SIZE may exceed this limit, high pfn bits are cropped and wrong address mapped by kmap_atomic_pfn in copy_oldmem_page. Don't allow this behavior in non-PAE kdump kernels by checking pfns passed into copy_oldmem_page. In the case of failure, userspace process gets EFAULT.

Commit 79e1dd05 "x86: Provide an alternative() based cmpxchg64()" broke lguest, even on systems which have cmpxchg8b support. The emulation code gets used until alternatives get run, but it contains native instructions, not their paravirt alternatives. The simplest fix is to turn this code off except for 386 and 486 builds.

When sending a NMI_VECTOR IPI using the UV_HUB_IPI_INT register, we need to ensure the delivery mode field of that register has NMI delivery selected. This makes those IPIs true NMIs, instead of flat IPIs. It matters to reboot sequences and KGDB, both of which use NMI IPIs.

The MCE initialization code explicitly says it doesn't handle asymmetric configurations where different CPUs support different numbers of MCE banks, and it prints a big warning in that case. Therefore, printing the "mce: CPU supports <x> MCE banks" message into the kernel log for every CPU is pure redundancy that clutters the log significantly for systems with lots of CPUs.

A few parts of the uv_hub_info structure are initialized incorrectly. - n_val is being loaded with m_val. - gpa_mask is initialized with a bytes instead of an unsigned long. - Handle the case where none of the alias registers are used. Lastly I converted the bau over to using the uv_hub_info->m_val which is the correct value. Without this patch, booting a large configuration hits a problem where the upper bits of the gnode affect the pnode and the bau will not operate.

Older binutils breaks if ASSERT() is used without a sink for the output.

The destination keyring specified to request_key() and co. is made available to the process that instantiates the key (the slave process started by /sbin/request-key typically). This is passed in the request_key_auth struct as the dest_keyring member. keyctl_instantiate_key and keyctl_negate_key() call get_instantiation_keyring() to get the keyring to attach the newly constructed key to at the end of instantiation. This may be given a specific keyring into which a link will be made later, or it may be asked to find the keyring passed to request_key(). In the former case, it returns a keyring with the refcount incremented by lookup_user_key(); in the latter case, it returns the keyring from the request_key_auth struct - and does _not_ increment the refcount. The latter case will eventually result in an oops when the keyring prematurely runs out of references and gets destroyed. The effect may take some time to show up as the key is destroyed lazily. To fix this, the keyring returned by get_instantiation_keyring() must always have its refcount incremented, no matter where it comes from. This can be tested by setting /etc/request-key.conf to: #OP TYPE DESCRIPTION CALLOUT INFO PROGRAM ARG1 ARG2 ARG3 ... #====== ======= =============== =============== =============================== create * test:* * |/bin/false %u %g %d %{user:_display} negate * * * /bin/keyctl negate %k 10 @u and then doing: keyctl add user _display aaaaaaaa @u while keyctl request2 user test:x test:x @u && keyctl list @u; do keyctl request2 user test:x test:x @u; sleep 31; keyctl list @u; done which will oops eventually. Changing the negate line to have @u rather than %S at the end is important as that forces the latter case by passing a special keyring ID rather than an actual keyring ID.
