| | | | | | | | | | | Intel hosts, without long mode, and with nx support disabled in the bios have an efer that is readable but not writable.

* [PATCH] __crc_... is intended to be absoluteAl Viro2007-02-011-0/+2
| | | | | | | | | | | | | | | | | | | i386 boot/compressed/relocs checks for absolute symbols and warns about unexpected ones. If you build with modversions, you get ~2500 warnings about __crc_<symbol>. These suckers are really absolute symbols - we do _not_ want to modify them on relocation. They are generated by genksyms - EXPORT_... generates a weak alias, then genksyms produces an ld script with __crc_<symbol> = <checksum> and it's fed to ld to produce the final object file. Their only use is to match kernel and module at modprobe time; they _must_ be absolute. boot/compressed/relocs has a whitelist of known absolute symbols, but it doesn't know about __crc_... stuff. As the result, we get shitloads of false positives on any ld(1) version. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * [IPV6]: fix BUG of ndisc_send_redirect()Li Yewang2007-01-301-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I tested IPv6 redirect function about kernel 2.6.19.1, and found that the kernel can send redirect packets whose target address is global address, and the target is not the actual endpoint of communication. But the criteria conform to RFC2461, the target address defines as following: Target Address An IP address that is a better first hop to use for he ICMP Destination Address. When the target is the actual endpoint of communication, i.e., the destination is a neighbor, the Target Address field MUST contain the same value as the ICMP Destination Address field. Otherwise the target is a better first-hop router and the Target Address MUST be the router's link-local address so that hosts can uniquely identify routers. According to this definition, when a router redirect to a host, the target address either the better first-hop router's link-local address or the same as the ICMP destination address field. But the function of ndisc_send_redirect() in net/ipv6/ndisc.c, does not check the target address correctly. There is another definition about receive Redirect message in RFC2461: 8.1. Validation of Redirect Messages A host MUST silently discard any received Redirect message that does not satisfy all of the following validity checks: ...... - The ICMP Target Address is either a link-local address (when redirected to a router) or the same as the ICMP Destination Address (when redirected to the on-link destination). ...... And the receive redirect function of ndisc_redirect_rcv() implemented this definition, checks the target address correctly. if (ipv6_addr_equal(dest, target)) { on_link = 1; } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) { ND_PRINTK2(KERN_WARNING "ICMPv6 Redirect: target address is not link-local.\n"); return; } So, I think the send redirect function must check the target address also.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The apple powerbook people are used to switch the pb_fnmode setting at runtime through writing to sysfs, altering the module parameter value. This was broken for them in 2.6.20-rc1 when generic HID layer was introduced, as the pb_fnmode flag was made per-hiddevice, instead of global variable. This patch moves the pb_fnmode module parameter from usbhid module to hid module, but apart from that retains backward compatibility with respect to changing the mode through sysfs.

| * | libata: fix translation for START STOP UNITRobert Hancock2007-01-301-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libata's SCSI translation for the SCSI START STOP UNIT command with the START bit clear (i.e. stopping the drive) appears to be incorrect. It sends an ATA STANDBY command with the time period set to 0, which the code comment says means "now", but the ATA standard says this means disable the standby timer, which effectively does nothing. Change this to issue a STANDBY IMMEDIATE command which will actually spin the drive down. The SAT (SCSI/ATA Translation) standard revision 9 concurs with this choice.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | User applications using the HDIO_DRIVE_TASK ioctl through libata expect specific ATA registers to be returned to userspace. Verified that ata_task_ioctl correctly returns register values to the smartctl application.
