The core st33zp24 module is useless without either the I2C or the SPI access module. So hide NFC_ST_NCI and select it automatically if either TCG_TIS_ST33ZP24_I2C or TCG_TIS_ST33ZP24_SPI is selected. This avoids presenting TCG_TIS_ST33ZP24 when neither TCG_TIS_ST33ZP24_I2C nor TCG_TIS_ST33ZP24_SPI can be selected.

This moves seccomp after ptrace on x86 to that seccomp can catch changes made by ptrace. Emulation should skip the rest of processing too. We can get rid of test_thread_flag because there's no longer any opportunity for seccomp to mess with ptrace state before invoking ptrace.

Currently, if arch code wants to supply seccomp_data directly to seccomp (which is generally much faster than having seccomp do it using the syscall_get_xyz() API), it has to use the two-phase seccomp hooks.

One problem with seccomp was that ptrace could be used to change a syscall after seccomp filtering had completed. This was a well documented limitation, and it was recommended to block ptrace when defining a filter to avoid this problem. This can be quite a limitation for containers or other places where ptrace is desired even under seccomp filters. This adds tests for both SECCOMP_RET_TRACE and PTRACE_SYSCALL manipulations.

The capability check should not be audited since it is only being used to determine the inode permissions. A failed check does not indicate a violation of security policy but, when an LSM is enabled, a denial audit message was being generated. The denial audit message caused confusion for some application authors because root-running Go applications always triggered the denial. To prevent this confusion, the capability check in net_ctl_permissions() is switched to the noaudit variant.

When checking the current cred for a capability in a specific user namespace, it isn't always desirable to have the LSMs audit the check. This patch adds a noaudit variant of ns_capable() for when those situations arise. The common logic between ns_capable() and the new ns_capable_noaudit() is moved into a single, shared function to keep duplicated code to a minimum and ease maintainability.

Serge Hallyn pointed out that the current implementation of security_inode_getsecurity() works if there is only one hook provided for it, but will fail if there is more than one and the attribute requested isn't supplied by the first module. This isn't a problem today, since only SELinux and Smack provide this hook and there is (currently) no way to enable both of those modules at the same time. Serge, however, wants to introduce a capability attribute and an inode_getsecurity hook in the capability security module to handle it. This addresses that upcoming problem, will be required for "extreme stacking" and is just a better implementation.

The /dev/ptmx device node is changed to lookup the directory entry "pts" in the same directory as the /dev/ptmx device node was opened in. If there is a "pts" entry and that entry is a devpts filesystem /dev/ptmx uses that filesystem. Otherwise the open of /dev/ptmx fails. The DEVPTS_MULTIPLE_INSTANCES configuration option is removed, so that userspace can now safely depend on each mount of devpts creating a new instance of the filesystem. Each mount of devpts is now a separate and equal filesystem. Reserved ttys are now available to all instances of devpts where the mounter is in the initial mount namespace. A new vfs helper path_pts is introduced that finds a directory entry named "pts" in the directory of the passed in path, and changes the passed in path to point to it. The helper path_pts uses a function path_parent_directory that was factored out of follow_dotdot. In the implementation of devpts: - devpts_mnt is killed as it is no longer meaningful if all mounts of devpts are equal. - pts_sb_from_inode is replaced by just inode->i_sb as all cached inodes in the tty layer are now from the devpts filesystem. - devpts_add_ref is rolled into the new function devpts_ptmx. And the unnecessary inode hold is removed. - devpts_del_ref is renamed devpts_release and reduced to just a deacrivate_super. - The newinstance mount option continues to be accepted but is now ignored. In devpts_fs.h definitions for when !CONFIG_UNIX98_PTYS are removed as they are never used. Documentation/filesystems/devices.txt is updated to describe the current situation. This has been verified to work properly on openwrt-15.05, centos5, centos6, centos7, debian-6.0.2, debian-7.9, debian-8.2, ubuntu-14.04.3, ubuntu-15.10, fedora23, magia-5, mint-17.3, opensuse-42.1, slackware-14.1, gentoo-20151225 (13.0?), archlinux-2015-12-01. With the caveat that on centos6 and on slackware-14.1 that there wind up being two instances of the devpts filesystem mounted on /dev/pts, the lower copy does not end up getting used.

Syscalls should never crash programs, but instead return EFAULT. The IIR register contains the executed instruction, which disassebles into "ldw 0(sr3,r5),r9". This load-word instruction is part of __get_user() which tried to read the word at %r5/IOR (0xfa6f7fff). This means the unaligned handler jumped in. The unaligned handler is able to emulate all ldw instructions, but it fails if it fails to read the source e.g. because of page fault. The following program reproduces the problem: #define _GNU_SOURCE #include <unistd.h> #include <sys/syscall.h> #include <sys/mman.h> int main(void) { /* allocate 8k */ char *ptr = mmap(NULL, 2*4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0); /* free second half (upper 4k) and make it invalid. */ munmap(ptr+4096, 4096); /* syscall where first int is unaligned and clobbers into invalid memory region */ /* syscall should return EFAULT */ return syscall(__NR_clock_adjtime, 0, ptr+4095); } To fix this issue we simply need to check if the faulting instruction address is in the exception fixup table when the unaligned handler failed. If it is, call the fixup routine instead of crashing. While looking at the unaligned handler I found another issue as well: The target register should not be modified if the handler was unsuccessful.

Mikulas Patocka authored
This patch fixes backtrace on PA-RISC There were several problems: 1) The code that decodes instructions handles instructions that subtract from the stack pointer incorrectly. If the instruction subtracts the number X from the stack pointer the code increases the frame size by (0x100000000-X). This results in invalid accesses to memory and recursive page faults. 2) Because gcc reorders blocks, handling instructions that subtract from the frame pointer is incorrect. For example, this function int f(int a) { if (__builtin_expect(a, 1)) return a; g(); return a; } is compiled in such a way, that the code that decreases the stack pointer for the first "return a" is placed before the code for "g" call. If we recognize this decrement, we mistakenly believe that the frame size for the "g" call is zero. To fix problems 1) and 2), the patch doesn't recognize instructions that decrease the stack pointer at all. To further safeguard the unwind code against nonsense values, we don't allow frame size larger than Total_frame_size. 3) The backtrace is not locked. If stack dump races with module unload, invalid table can be accessed. This patch adds a spinlock when processing module tables. Note, that for correct backtrace, you need recent binutils. Binutils 2.18 from Debian 5 produce garbage unwind tables. Binutils 2.21 work better (it sometimes forgets function frames, but at least it doesn't generate garbage).
