[ Upstream commit 7261b956 ] The patch to add it_page_shift incorrectly changed the increment of uaddr to use it_page_shift, rather then (1 << it_page_shift). This broke booting on at least some Cell blades, as the iommu was basically non-functional. Fixes: 3a553170 ("powerpc/iommu: Add it_page_shift field to determine iommu page size") Signed-off-by:

[ Upstream commit b0dd00ad ] The conversion from __get_cpu_var() to this_cpu_ptr() in iic_setup_cpu() is wrong. It causes an oops at boot. We need the per-cpu address of struct cpu_iic, not cpu_iic.regs->prio. Sparse noticed this, because we pass a non-iomem pointer to out_be64(), but we obviously don't check the sparse results often enough.

[ Upstream commit f7e9e358 ] This problem appears to have been introduced in 2.6.29 by commit 93197a36 "Rewrite sysfs processor cache info code". This caused lscpu to error out on at least e500v2 devices, eg: error: cannot open /sys/devices/system/cpu/cpu0/cache/index2/size: No such file or directory Some embedded powerpc systems use cache-size in DTS for the unified L2 cache size, not d-cache-size, so we need to allow for both DTS names. Added a new CACHE_TYPE_UNIFIED_D cache_type_info structure to handle this. Fixes: 93197a36 ("powerpc: Rewrite sysfs processor cache info code") Signed-off-by:

[ Upstream commit 027fa02f ] If M64 has been supported, the prefetchable 64-bits memory resources shouldn't be mapped to the corresponding PE# via M32DT. Unfortunately, we're doing that in pnv_ioda_setup_pe_seg() wrongly. The issue was introduced by commit 262af557 ("powerpc/powernv: Enable M64 aperatus for PHB3"). The patch fixes the issue by simply skipping M64 resources when updating to M32DT. Cc: <stable@vger.kernel.org> # v3.17+ Signed-off-by:

[ Upstream commit c8367778 ] In fd_do_prot_rw(), it allocates prot_buf which is used to copy from se_cmd->t_prot_sg by sbc_dif_copy_prot(). The SG table for prot_buf is also initialized by allocating 'se_cmd->t_prot_nents' entries of scatterlist and setting the data length of each entry to PAGE_SIZE at most. However if se_cmd->t_prot_sg contains a clustered entry (i.e. sg->length > PAGE_SIZE), the SG table for prot_buf can't be initialized correctly and sbc_dif_copy_prot() can't copy to prot_buf. (This actually happened with TCM loopback fabric module) As prot_buf is allocated by kzalloc() and it's physically contiguous, we only need a single scatterlist entry. Signed-off-by:

[ Upstream commit 64d240b7 ] When UNMAP command is issued with DIF protection support enabled, the protection info for the unmapped region is remain unchanged. So READ command for the region causes data integrity failure. This fixes it by invalidating protection info for the unmapped region by filling with 0xff pattern. This change also adds helper function fd_do_prot_fill() in order to reduce code duplication with existing fd_format_prot(). Signed-off-by:

[ Upstream commit 38da0f49 ] When CONFIG_DEBUG_SG=y and DIF protection support enabled, kernel BUG()s are triggered due to the following two issues: 1) prot_sg is not initialized by sg_init_table(). When CONFIG_DEBUG_SG=y, scatterlist helpers check sg entry has a correct magic value. 2) vmalloc'ed buffer is passed to sg_set_buf(). sg_set_buf() uses virt_to_page() to convert virtual address to struct page, but it doesn't work with vmalloc address. vmalloc_to_page() should be used instead. As prot_buf isn't usually too large, so fix it by allocating prot_buf by kmalloc instead of vmalloc. Signed-off-by:

[ Upstream commit c8e63985 ] This patch fixes a bug for COMPARE_AND_WRITE handling with fabrics using SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC. It adds the missing allocation for cmd->t_bidi_data_sg within transport_generic_new_cmd() that is used by COMPARE_AND_WRITE for the initial READ payload, even if the fabric is already providing a pre-allocated buffer for cmd->t_data_sg. Also, fix zero-length COMPARE_AND_WRITE handling within the compare_and_write_callback() and target_complete_ok_work() to queue the response, skipping the initial READ. This fixes COMPARE_AND_WRITE emulation with loopback, vhost, and xen-backend fabric drivers using SG_TO_MEM_NOALLOC. Reported-by:

[ Upstream commit f82263c6 ] Since commit ee0778a3 ("tools/power: turbostat: make Makefile a bit more capable") turbostat's Makefile is using [...] BUILD_OUTPUT := $(PWD) [...] which obviously causes trouble when building "turbostat" with make -C /usr/src/linux/tools/power/x86/turbostat ARCH=x86 turbostat because GNU make does not update nor guarantee that $PWD is set. This patch changes the Makefile to use $CURDIR instead, which GNU make guarantees to set and update (i.e. when using "make -C ...") and also adds support for the O= option (see "make help" in your root of your kernel source tree for more details).

[ Upstream commit 8318e667 ] Invoking mount propagation from __detach_mounts is inefficient and wrong. It is inefficient because __detach_mounts already walks the list of mounts that where something needs to be done, and mount propagation walks some subset of those mounts again. It is actively wrong because if the dentry that is passed to __detach_mounts is not part of the path to a mount that mount should not be affected. change_mnt_propagation(p,MS_PRIVATE) modifies the mount propagation tree of a master mount so it's slaves are connected to another master if possible. Which means even removing a mount from the middle of a mount tree with __detach_mounts will not deprive any mount propagated mount events. Cc: stable@vger.kernel.org Signed-off-by:

[ Upstream commit e12fb972 ] Previously commit 14ece102 added a support for for syncing parent directory of newly created inodes to make sure that the inode is not lost after a power failure in no-journal mode. However this does not work in majority of cases, namely: - if the directory has inline data - if the directory is already indexed - if the directory already has at least one block and: - the new entry fits into it - or we've successfully converted it to indexed So in those cases we might lose the inode entirely even after fsync in the no-journal mode. This also includes ext2 default mode obviously. I've noticed this while running xfstest generic/321 and even though the test should fail (we need to run fsck after a crash in no-journal mode) I could not find a newly created entries even when if it was fsynced before. Fix this by adjusting the ext4_add_entry() successful exit paths to set the inode EXT4_STATE_NEWENTRY so that fsync has the chance to fsync the parent directory as well. Signed-off-by:

[ Upstream commit b72c1869 ] ptrace_resume() is called when the tracee is still __TASK_TRACED. We set tracee->exit_code and then wake_up_state() changes tracee->state. If the tracer's sub-thread does wait() in between, task_stopped_code(ptrace => T) wrongly looks like another report from tracee. This confuses debugger, and since wait_task_stopped() clears ->exit_code the tracee can miss a signal. Test-case: #include <stdio.h> #include <unistd.h> #include <sys/wait.h> #include <sys/ptrace.h> #include <pthread.h> #include <assert.h> int pid; void *waiter(void *arg) { int stat; for (;;) { assert(pid == wait(&stat)); assert(WIFSTOPPED(stat)); if (WSTOPSIG(stat) == SIGHUP) continue; assert(WSTOPSIG(stat) == SIGCONT); printf("ERR! extra/wrong report:%x\n", stat); } } int main(void) { pthread_t thread; pid = fork(); if (!pid) { assert(ptrace(PTRACE_TRACEME, 0,0,0) == 0); for (;;) kill(getpid(), SIGHUP); } assert(pthread_create(&thread, NULL, waiter, NULL) == 0); for (;;) ptrace(PTRACE_CONT, pid, 0, SIGCONT); return 0; } Note for stable: the bug is very old, but without 9899d11f "ptrace: ensure arch_ptrace/ptrace_request can never race with SIGKILL" the fix should use lock_task_sighand(child).

[ Upstream commit a87938b2 ] With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base. Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the "gap" between the stack and the binary. Since the size of the "gap" on x86_64 is only guaranteed to be 128MB this means that binaries with large data segments > 128MB can end up mapping part of their data segment over their stack resulting in corruption of the stack (and the data segment once the binary starts to run). Any PIE binary with a data segment > 128MB is vulnerable to this although address randomization means that the actual gap between the stack and the end of the binary is normally greater than 128MB. The larger the data segment of the binary the higher the probability of failure. Fix this by calculating the total size of the binary in the same way as load_elf_interp(). Signed-off-by:
