2016-12-22fs: exec: apply CLOEXEC before changing dumpable task flagsAleksa Sarai1-2/+8
If you have a process that has set itself to be non-dumpable, and it then undergoes exec(2), any CLOEXEC file descriptors it has open are "exposed" during a race window between the dumpable flags of the process being reset for exec(2) and CLOEXEC being applied to the file descriptors. This can be exploited by a process by attempting to access /proc/<pid>/fd/... during this window, without requiring CAP_SYS_PTRACE. The race in question is after set_dumpable has been (for get_link, though the trace is basically the same for readlink): [vfs] -> proc_pid_link_inode_operations.get_link -> proc_pid_get_link -> proc_fd_access_allowed -> ptrace_may_access(task, PTRACE_MODE_READ_FSCREDS); Which will return 0, during the race window and CLOEXEC file descriptors will still be open during this window because do_close_on_exec has not been called yet. As a result, the ordering of these calls should be reversed to avoid this race window. This is of particular concern to container runtimes, where joining a PID namespace with file descriptors referring to the host filesystem can result in security issues (since PRCTL_SET_DUMPABLE doesn't protect against access of CLOEXEC file descriptors -- file descriptors which may reference filesystem objects the container shouldn't have access to).

2016-12-22seq_file: reset iterator to first record for zero offsetTomasz Majchrzak1-0/+7
If kernfs file is empty on a first read, successive read operations using the same file descriptor will return no data, even when data is available. Default kernfs 'seq_next' implementation advances iterator position even when next object is not there. Kernfs 'seq_start' for following requests will not return iterator as position is already on the second object. This defect doesn't allow to monitor badblocks sysfs files from MD raid. They are initially empty but if data appears at some stage, userspace is not able to read it.

2016-12-22[iov_iter] fix iterate_all_kinds() on empty iteratorsAl Viro1-29/+26
Problem similar to ones dealt with in "fold checks into iterate_and_advance()" and followups, except that in this case we really want to do nothing when asked for zero-length operation - unlike zero-length iterate_and_advance(), zero-length iterate_all_kinds() has no side effects, and callers are simpler that way. That got exposed when copy_from_iter_full() had been used by tipc, which builds an msghdr with zero payload and (now) feeds it to a primitive based on iterate_all_kinds() instead of iterate_and_advance().

2016-12-22IB/rxe: Drop future atomic/read packets rather than retryingAndrew Boyer1-1/+1
If the completer is in the middle of a large read operation, one lost packet can cause havoc. Going to COMPST_ERROR_RETRY will cause the requester to resend the request. After that, any packet from the first attempt still in the receive queue will be interpreted as an error, restarting the error/retry sequence. The transfer will quickly exhaust its retries. This behavior is very noticeable when doing 512KB reads on a QEMU system configured with 1500B MTU. Also, a resent request here will prompt the responder on the other side to immediately start resending, but the resent packets will get stuck in the already-loaded receive queue and will never be processed. Rather than erroring out every time an unexpected future packet arrives, just drop it. Eventually the retry timer will send a duplicate request; the completer will be able to make progress since the queue will start relatively empty.

Commit 3322d0d64f4e ("selinux: keep SELinux in sync with new capability definitions") added a check on the defined capabilities without explicitly including the capability header file which caused problems when building genheaders for users of clang/llvm. Resolve this by using the kernel headers when building genheaders, which is arguably the right thing to do regardless, and explicitly including the kernel's capability.h header file in classmap.h. We also update the mdp build, even though it wasn't causing an error we really should be using the headers from the kernel we are building.

2016-12-21mmc: sd: Meet alignment requirements for raw_ssr DMAPaul Burton1-2/+10
The mmc_read_ssr() function results in DMA to the raw_ssr member of struct mmc_card, which is not guaranteed to be cache line aligned & thus might not meet the requirements set out in Documentation/DMA-API.txt: Warnings: Memory coherency operates at a granularity called the cache line width. In order for memory mapped by this API to operate correctly, the mapped region must begin exactly on a cache line boundary and end exactly on one (to prevent two separately mapped regions from sharing a single cache line). Since the cache line size may not be known at compile time, the API will not enforce this requirement. Therefore, it is recommended that driver writers who don't take special care to determine the cache line size at run time only map virtual regions that begin and end on page boundaries (which are guaranteed also to be cache line boundaries). On some systems where DMA is non-coherent this can lead to us losing data that shares cache lines with the raw_ssr array. Fix this by kmalloc'ing a temporary buffer to perform DMA into. kmalloc will ensure the buffer is suitably aligned, allowing the DMA to be performed without any loss of data.

This patch removes the users of the deprectated APIs: acpi_get_table_with_size() early_acpi_os_unmap_memory() The following APIs should be used instead of: acpi_get_table() acpi_put_table() The deprecated APIs are invented to be a replacement of acpi_get_table() during the early stage so that the early mapped pointer will not be stored in ACPICA core and thus the late stage acpi_get_table() won't return a wrong pointer. The mapping size is returned just because it is required by early_acpi_os_unmap_memory() to unmap the pointer during early stage. But as the mapping size equals to the acpi_table_header.length (see acpi_tb_init_table_descriptor() and acpi_tb_validate_table()), when such a convenient result is returned, driver code will start to use it instead of accessing acpi_table_header to obtain the length. Thus this patch cleans up the drivers by replacing returned table size with acpi_table_header.length, and should be a no-op.

2016-12-21ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernelLv Zheng7-54/+220
ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07 This patch back ports Linux acpi_get_table_with_size() and early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences. The 2 APIs are used by Linux as table management APIs for long time, it contains a hidden logic that during the early stage, the mapped tables should be unmapped before the early stage ends. During the early stage, tables are handled by the following sequence: acpi_get_table_with_size(); parse the table early_acpi_os_unmap_memory(); During the late stage, tables are handled by the following sequence: acpi_get_table(); parse the table Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the late stage. The reasoning of introducing acpi_get_table_with_size() is: ACPICA will remember the early mapped pointer in acpi_get_table() and Linux isn't able to prevent ACPICA from using the wrong early mapped pointer during the late stage as there is no API provided from ACPICA to be an inverse of acpi_get_table() to forget the early mapped pointer. But how ACPICA can work with the early/late stage requirement? Inside of ACPICA, tables are ensured to be remained in "INSTALLED" state during the early stage, and they are carefully not transitioned to "VALIDATED" state until the late stage. So the same logic is in fact implemented inside of ACPICA in a different way. The gap is only that the feature is not provided to the OSPMs in an accessible external API style. It then is possible to fix the gap by providing an inverse of acpi_get_table() from ACPICA, so that the two Linux sequences can be combined: acpi_get_table(); parse the table acpi_put_table(); In order to work easier with the current Linux code, acpi_get_table() and acpi_put_table() is implemented in a usage counting based style: 1. When the usage count of the table is increased from 0 to 1, table is mapped and .Pointer is set with the mapping address (VALIDATED); 2. When the usage count of the table is decreased from 1 to 0, .Pointer is unset and the mapping address is unmapped (INVALIDATED). So that we can deploy the new APIs to Linux with minimal effort by just invoking acpi_get_table() in acpi_get_table_with_size() and invoking acpi_put_table() in early_acpi_os_unmap_memory().
