Add an option to configure mapping of Inbound Window without RIO-to-PCIe address translation. If a local memory buffer is not properly aligned to meet HW requirements for RapidIO address mapping with address translation, caller can request an inbound window with matching RapidIO address assigned to it. This implementation selects RapidIO base address and size for inbound window that are capable to accommodate the local memory buffer. Signed-off-by:

Alexandre Bounine authored
Add check for attempts to request mapping of inbound RapidIO address space that overlaps with existing active mapping windows. Tsi721 device does not support overlapped inbound windows and SRIO address decoding behavior is not defined in such cases. This patch is applicable to kernel versions starting from v3.7.

Remove use of hardcoded setting for Maximum Read Request Size (MRRS) value and use one set by PCIe bus driver. Using hardcoded value can cause PCIe bus errors on platforms that have tsi721 device on PCIe path that allows only smaller read request sizes. This fix is applicable to kernel versions starting from v3.2. Signed-off-by:

These patches are the result of extensive collaboration within the RapidIO.org Software Task Group between Texas Instruments, Freescale, Prodrive Technologies, Nokia Networks, BAE and IDT. Additional input was received from other members of RapidIO.org. The objective was to create a character mode driver interface which exposes the capabilities of RapidIO devices directly to applications, in a manner that allows the numerous and varied RapidIO implementations to interoperate. The Software Task Group has also developed fabric management, Remote Memory Access, and sockets applications which make use of these interfaces in user space. Intensive testing with these applications prompted the RapidIO subsystem updates provided within this set of patches. This patch (of 29): Replace default Ethernet-specific routine by the custom one to allow setting of larger MTU supported by RapidIO messaging (max RIO packet size is 4096 bytes). Signed-off-by:

This commit fixes the following security hole affecting systems where all of the following conditions are fulfilled: - The fs.suid_dumpable sysctl is set to 2. - The kernel.core_pattern sysctl's value starts with "/". (Systems where kernel.core_pattern starts with "|/" are not affected.) - Unprivileged user namespace creation is permitted. (This is true on Linux >=3.8, but some distributions disallow it by default using a distro patch.) Under these conditions, if a program executes under secure exec rules, causing it to run with the SUID_DUMP_ROOT flag, then unshares its user namespace, changes its root directory and crashes, the coredump will be written using fsuid=0 and a path derived from kernel.core_pattern - but this path is interpreted relative to the root directory of the process, allowing the attacker to control where a coredump will be written with root privileges. To fix the security issue, always interpret core_pattern for dumps that are written under SUID_DUMP_ROOT relative to the root directory of init. Signed-off-by:

This test-case (simplified version of generated by syzkaller) #include <unistd.h> #include <sys/ptrace.h> #include <sys/wait.h> void test(void) { for (;;) { if (fork()) { wait(NULL); continue; } ptrace(PTRACE_SEIZE, getppid(), 0, 0); ptrace(PTRACE_INTERRUPT, getppid(), 0, 0); _exit(0); } } int main(void) { int np; for (np = 0; np < 8; ++np) if (!fork()) test(); while (wait(NULL) > 0) ; return 0; } triggers the 2nd WARN_ON_ONCE(!signr) warning in do_jobctl_trap(). The problem is that __ptrace_unlink() clears task->jobctl under siglock but task->ptrace is cleared without this lock held; this fools the "else" branch which assumes that !PT_SEIZED means PT_PTRACED. Note also that most of other PTRACE_SEIZE checks can race with detach from the exiting tracer too. Say, the callers of ptrace_trap_notify() assume that SEIZED can't go away after it was checked.

FAT has long supported its own default file name encoding config setting, separate from CONFIG_NLS_DEFAULT. However, if UTF-8 encoded file names are desired FAT character set should not be set to utf8 since this would make file names case sensitive even if case insensitive matching is requested. Instead, "utf8" mount options should be provided to enable UTF-8 file names in FAT file system. Unfortunately, there was no possibility to set the default value of this option so on UTF-8 system "utf8" mount option had to be added manually to most FAT mounts. This patch adds config option to set such default value. Signed-off-by:

x86's is_compat_task always checked the current syscall type, not the task type. It has no non-arch users any more, so just remove it to avoid confusion. On x86, nothing should really be checking the task ABI. There are legitimate users for the syscall ABI and for the mm ABI. Signed-off-by:

The input compat code should work like all other compat code: for 32-bit syscalls, use the 32-bit ABI and for 64-bit syscalls, use the 64-bit ABI. We have a helper for that (in_compat_syscall()): just use it. Signed-off-by:

amdkfd wants to know syscall type, not task type. Check directly. Unfortunately, amdkfd is making nasty assumptions that a process' bitness is a well-defined constant thing. This isn't the case on x86. I don't know how much this matters, but this patch has no effect on generated code on x86, so amdkfd is equally broken with and without this patch. Signed-off-by:

This should make no difference on any architecture, as x86's historical is_compat_task behavior really did check whether the calling syscall was a compat syscall. x86's is_compat_task is going away, though. Signed-off-by:

Except on SPARC, this is what the code always did. SPARC compat seccomp was buggy, although the impact of the bug was limited because SPARC 32-bit and 64-bit syscall numbers are the same. Signed-off-by:

Users of the 32-bit ptrace() ABI expect the full 32-bit ABI. siginfo translation should check ptrace() ABI, not caller task ABI. This is an ABI change on SPARC. Let's hope that no one relied on the old buggy ABI. Signed-off-by:

Seccomp wants to know the syscall bitness, not the caller task bitness, when it selects the syscall whitelist. As far as I know, this makes no difference on any architecture, so it's not a security problem. (It generates identical code everywhere except sparc, and, on sparc, the syscall numbering is the same for both ABIs.) Signed-off-by:

Sparc's syscall_get_arch was buggy: it returned the task arch, not the syscall arch. This could confuse seccomp and audit. I don't think this is as bad for seccomp as it looks: sparc's 32-bit and 64-bit syscalls are numbered the same. Signed-off-by:

Andy Lutomirski authored
On sparc64 compat-enabled kernels, any task can make 32-bit and 64-bit syscalls. is_compat_task returns true in 32-bit tasks, which does not necessarily imply that the current syscall is 32-bit. Provide an in_compat_syscall implementation that checks whether the current syscall is compat. As far as I know, sparc is the only architecture on which is_compat_task checks the compat status of the task and on which the compat status of a syscall can differ from the compat status of the task. On x86, is_compat_task checks the syscall type, not the task type. [akpm@linux-foundation.org: add comment, per Sam] [akpm@linux-foundation.org: update comment, per Andy] Signed-off-by:

When new timeout is written to /proc/sys/kernel/hung_task_timeout_secs, khungtaskd is interrupted and again sleeps for full timeout duration. This means that hang task will not be checked if new timeout is written periodically within old timeout duration and/or checking of hang task will be delayed for up to previous timeout duration. Fix this by remembering last time khungtaskd checked hang task. This change will allow other watchdog tasks (if any) to share khungtaskd by sleeping for minimal timeout diff of all watchdog tasks. Doing more watchdog tasks from khungtaskd will reduce the possibility of printk() collisions by multiple watchdog threads. Signed-off-by:

Commit b430e9d1 ("remove compressed copy from zram in-memory") applied swap_slot_free_notify call in *end_swap_bio_read* to remove duplicated memory between zram and memory. However, with the introduction of rw_page in zram: 8c7f0102 ("zram: implement rw_page operation of zram"), it became void because rw_page doesn't need bio. Memory footprint is really important in embedded platforms which have small memory, for example, 512M) recently because it could start to kill processes if memory footprint exceeds some threshold by LMK or some similar memory management modules. This patch restores the function for rw_page, thereby eliminating this duplication. Signed-off-by:

This document will describe OCFS2 online file check feature. OCFS2 is often used in high-availaibility systems. However, OCFS2 usually converts the filesystem to read-only when encounters an error. This may not be necessary, since turning the filesystem read-only would affect other running processes as well, decreasing availability. Then, a mount option (errors=continue) is introduced, which would return the -EIO errno to the calling process and terminate furhter processing so that the filesystem is not corrupted further. The filesystem is not converted to read-only, and the problematic file's inode number is reported in the kernel log. The user can try to check/fix this file via online filecheck feature.

Gang He authored
When there are errors in the ocfs2 filesystem, they are usually accompanied by the inode number which caused the error. This inode number would be the input to fixing the file. One of these options could be considered: A file in the sys filesytem which would accept inode numbers. This could be used to communication back what has to be fixed or is fixed. You could write: $# echo "<inode>" > /sys/fs/ocfs2/devname/filecheck/check or $# echo "<inode>" > /sys/fs/ocfs2/devname/filecheck/fix Compare with second version, I re-design filecheck sysfs interfaces, there are three sysfs files (check, fix and set) under filecheck directory (see above), sysfs will accept only one argument <inode>. Second, I adjust some code in ocfs2_filecheck_repair_inode_block() function according to upstream feedback, we cannot just add VALID_FL flag back as a inode block fix, then we will not fix this field corruption currently until having a complete solution. Compare with first version, I use strncasecmp instead of double strncmp functions. Second, update the source file contribution vendor. This patch (of 4): Export ocfs2_kset object from ocfs2_stackglue kernel module, then online file check code will create the related sysfiles under ocfs2_kset object. We're exporting this because it's built in ocfs2_stackglue.ko. Signed-off-by:

Pull MMC updates from Ulf Hansson: "MMC core: - Fix ABI regression of MMC BLK ioctl - Remove the unused MMC_DATA_STREAM flag - Enable asynchronous system PM for the host device - Minor fixes and clean-ups SDHCI host: Throughout the years, the numbers of SDHCI variants have increased and so has also the numbers of SDHCI callbacks/quirks. The purpose of these callbacks/quirks were to enable SDHCI to deal with variant specific requirements, but unfortunate this method didn't scale. Instead we have ended up with a mess. Not only did the code become suboptimal but also highly fragile. Lately many discussions of how to move forward with SDHCI has taken place at the MMC mailing list. Step by step, we aim to turn SDHCI's common code into a set of library functions. This will enable for optimizations and allow some of the existing callbacks and quirks to be removed, which also should help to make the code less fragile. Therefore I am also really pleased to announce that Adrian Hunter (Intel) has volunteered to step in as the maintainer for SDHCI. Future wise, I hope the community around SDHCI will continue to grow and that this release cycle can be the starting point of moving SDHCI into a better shape. As a matter of fact, already in this cycle the re-factoring has begun, but of course there are also fixes and new features included.
