This patch for SELinux fixes a bug in the mapping of socket types to security classes and ensures that Unix seqpacket sockets are mapped to an appropriate security class. The Unix stream security class is re-used in this case as it has the same permission checking applied as for seqpacket. Signed-off-by:

We just spent some days fighting a rare race in one of the distro's who backported some of timer.c from 2.6 to 2.4 (though they missed a bit). The actual race we found didn't happen in 2.6 _but_ code inspection showed that a similar race is still present in 2.6, explanation below: Code removing a timer from a list (run_timers or del_timer) takes that CPU list lock, does list_del, then timer->base = NULL. It is mandatory that this timer->base = NULL is visible to other CPUs only after the list_del() is complete. If not, then mod timer could see it NULL, thus take it's own CPU list lock and not the one for the CPU the timer was beeing removed from the list, and thus the list_add in mod_timer() could race with the list_del() from run_timers() or del_timer(). Our race happened with run_timers(), which _DOES_ contain a proper smp_wmb() in the right spot in 2.6, but didn't in the "backport" we were fighting with. However, del_timer() doesn't have such a barrier, and thus is subject to this race in 2.6 as well. This patch fixes it. Signed-off-by:

The "udbg" code used on ppc64 for early consoles including early serial console recently got a new "default speed" option. This was implemented as a switch case that missed a few important cases, one beeing necessary for a board beeing released soon. This patch fixes it by using the proper division to calculate the dll value for the uart instead of that bogus switch/case. Signed-off-by:

The pci_bus_to_host() inline function used on ppc64 to find the pci_contoller structure a give pci_bus resides on used to contain bogus tree walking code, which fortunately ended up never beeing necessary since "sysdata" always points to a device_node structure that has the proper "phb" field (even if it is not the device-node of the actual P2P, which happens during boot).

This patch fixes a typo in the code that parse Open Firmware properties for devices under an "isa" node, the incorrect struct size was used when parsing the "reg" property of these. Signed-off-by:

The ppc64 kernel can be built with a default command line (CONFIG_CMDLINE) for cases where none is provided by the firmware. However, some OF implementation always pass a "bootargs" property that only contains the "0" terminating byte of a C string which caused us to think there was a command line, and not use the built-in one. This patch fixes it. Signed-off-by:

From Guido Guenther <agx@sigxcpu.org> this patch against 2.6.10-rc2 finally detects rivafb on NV30 based power books by adding the pciid. Wolfram Quester tested it and reported it working. It also cleans up the error code reported from the probe function. From Antonino Daplas <adaplas@pol.net> - do not validate mode if monitor specifications are not available Signed-Off-By:

ChangeSet "adaplas: [PATCH] fbdev: Add __iomem annotations to hgafb" had actually broken it - it not only added a (useless) cast in rowaddr(), it had also added a dereferencing. Since it is video memory and since we do memory transfers on the resulting "address"... IOW, it's even exploitable - not that there had been a lot of HGA boxen out there, but... This restores the intended behaviour. Signed-off-by:

here is a fix to a previous ChangeSet from John; 32-bit emulation of flock(fd, F_GETLK, &lock) currently is broken. The ChangeSet: http://linux.bkbits.net:8080/linux-2.5/cset%404152257aJKu1UClRcfvhsK6IjGYSeQ?nav=index.html|ChangeSet@-12w from John Engel <jhe@us.ibm.com> fixes an off-by-one error and according to the ChangeSet comment, it also contains a fix to handle l_len < 0 which is now defined in POSIX 1003.1-2001 from the fcntl man page. Gordon Jin <gordon.jin@intel.com> reports that the added test causes compat_sys_fcntl[64] to fail: If fcntl(fd, F_GETLK, &lock) finds no conflicting lock it sets l_whence to F_UNLCK, leaves all the other fields unchanged, and returns 0. The (f.l_start < 0) test wrongly converts this to an EINVAL result. The underlying sys_fcntl function which compat_sys_fcntl and compat_sys_fcntl64 invoke already handles POSIX behavior correctly. The additional tests in the compat wrappers are not needed. Here is a test case; its expected result is: PASS get flock: l_type=1, l_whence=0, l_start=145, l_len=10 #include <stdlib.h> #include <unistd.h> #include <fcntl.h> #include <errno.h> #include <stdio.h> int main(int argc, char *argv[]) { int fd; struct flock fl; char buf[255]; fl.l_type = F_WRLCK; fl.l_whence = SEEK_END; fl.l_start = -100; fl.l_len = -10; /* fl.l_whence = SEEK_SET; fl.l_start = 100; fl.l_len = 10; */ switch(fork()) { case -1: perror("fork"); exit(-1); case 0: fd = open("/tmp/testfile", O_RDWR|O_CREAT, 0600); if (fd == -1) { perror("open"); exit(-1); } if (write(fd, buf, 255) == -1) { perror("write"); exit(-1); } if (fcntl(fd, F_SETLK, &fl) == -1) { perror("F_SETLK"); exit(-1); } sleep(2); break; default: sleep(1); fd = open("/tmp/testfile", O_RDWR|O_CREAT, 0600); if (fd == -1) { perror("open"); exit(-1); } if (fcntl(fd, F_SETLK, &fl) != -1 || errno != EAGAIN) { perror("F_SETLK"); exit(1); } fl.l_type = F_WRLCK; /* fl.l_whence = SEEK_SET; fl.l_start = 0; fl.l_len = 0; */ if (fcntl(fd, F_GETLK, &fl) == -1) { perror("F_GETLK"); printf("FAIL\n"); exit(-1); } printf("PASS\n"); printf("get flock: l_type=%d, l_whence=%d, l_start=%zd, " "l_len=%zd\n", fl.l_type, fl.l_whence, (size_t) fl.l_start, (size_t) fl.l_len); break; } exit(0); } Signed-off-by:

* s_4bri.c has a nasty typo - bogus & in qBri_cpu_trapped(). We have void *base; followed by regs[0] = READ_DWORD((&base + offset) + 0x70); which is *NOT* what is meant there - instead of access to memory pointed to by base we get access to _stack_ at some offset from the place where the local variable base lives.
