2008-05-01rt2x00: Fix quality/activity led handlingIvo van Doorn
There was an obvious typo in LED structure initialization which caused the radio and quality/activity leds to be incorrectly initialized which resulted in the leds not being enabled. Additionally add the rt2x00led_led_activity() handler that will enable TX/RX activity leds when the radio is being enabled. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

direct_mask will be set when we are not associated and requesting a direct scan. The second debug print will be confusing as priv->essid is not set at that time and it will thus print "<hidden>" while it is known to which AP a direct scan is requested - as previous debug message also indicates.

2008-04-30Fix dnotify/close raceAl Viro
We have a race between fcntl() and close() that can lead to dnotify_struct inserted into inode's list *after* the last descriptor had been gone from current->files. Since that's the only point where dnotify_struct gets evicted, we are screwed - it will stick around indefinitely. Even after struct file in question is gone and freed. Worse, we can trigger send_sigio() on it at any later point, which allows to send an arbitrary signal to arbitrary process if we manage to apply enough memory pressure to get the page that used to host that struct file and fill it with the right pattern...

2008-04-30x86: Mark OPTIMIZE_INLINING brokenLinus Torvalds
So Ingo finally did figure out why UML broke with this option: UML passes gcc the -fno-unit-at-a-time flag, and apparently that wreaks havoc with gcc's inlining. We could turn off -fno-unit-at-a-time for UML for gcc4+ (which is what x86 does), but there's bad blood about this whole option, and it does show that the thing is just fragile as heck. So let tempers cool, and disable the thing, and we can revisit the decision later.

2008-04-30sysfs: Disallow truncation of files in sysfsBen Hutchings
sysfs allows attribute files to be truncated, e.g. using ftruncate(), with the expected effect on their inode. For most attributes, this doesn't change the "real" size of the file i.e. how much can be read from it. However, the parameter validation for reading and writing binary attribute files is based on the inode size and not the size specified in the file's bin_attribute, so it can be broken by this. For example, if we try using dd to write to such a file: # pwd /sys/bus/pci/devices/0000:08:00.0 # ls -l config -rw-r--r-- 1 root root 4096 Feb 1 17:35 config # dd if=/dev/zero of=config bs=4 count=1 1+0 records in 1+0 records out # ls -l config -rw-r--r-- 1 root root 0 Feb 1 17:50 config # dd if=/dev/zero of=config bs=4 count=1 seek=128 dd: writing `config': No space left on device 1+0 records in 0+0 records out Also, after truncation to 0, parameter validation for read and write is disabled. Most bin_attribute read and write methods also validate the size and offset, but for some this will allow out-of-range access. This may be a security issue, though access to such files is often limited to root. In any case, the validation should remain for safety's sake!) This was previously reported in Bugzilla as bug 9867. sysfs should ignore size changes or else refuse them (by returning -EINVAL). This patch makes it ignore them.

2008-04-30x86: ioremap ram check fixAndres Salomon
bdd3cee2e4b7279457139058615ced6c2b41e7de (x86: ioremap(), extend check to all RAM pages) breaks OLPC's ioremap call. The ioremap that OLPC uses is: romsig = ioremap(0xffffffc0, 16); The commit that breaks it is basically: - for (pfn = phys_addr >> PAGE_SHIFT; pfn < max_pfn_mapped && - (pfn << PAGE_SHIFT) < last_addr; pfn++) { + for (pfn = phys_addr >> PAGE_SHIFT; + (pfn << PAGE_SHIFT) < last_addr; pfn++) { + Previously, the 'pfn < max_pfn_mapped' check would've caused us to not enter the loop. Removing that check means we loop infinitely. The reason for that is because pfn is 0xfffff, and last_addr is 0xffffffcf. The remaining check that is used to exit the loop is not sufficient; when pfn<<PAGE_SHIFT is 0xfffff000, that is less than 0xffffffcf; when we increment pfn and it overflows (pfn == 0x100000), pfn<<PAGE_SHIFT ends up being 0. That, of course, is less than last_addr. In effect, pfn<<PAGE_SHIFT is never lower than last_addr. The simple fix for this is to limit the last_addr check to the PAGE_MASK; a patch is below.

2008-04-30x86: fix HT cpu booting on 32-bitHugh Dickins
Since recent smpboot 32/64-bit merge, my dual Xeon with HT has been booting only 2 of its 4 cpus (when running an i386 kernel; but x86_64 is okay). J.A. Magallón reports the same. native_cpu_up: bad cpu 2 native_cpu_up: bad cpu 3 The mach-default cpu_present_to_apicid() was just returning cpu number (2, 3) instead of apicid (6, 7): looks like we now need the x86_64 code even for the i386 case. Comparing with other versions of cpu_present_to_apicid(), it seems a good idea to include an NR_CPUS test too, since cpu_present() doesn't include that; but that wasn't a problem here, and may no problem at all. Prior to that smpboot merge, my Xeon booted the two HT siblings on one physical first, then the two siblings on the other physical after - when i386, but alternated them when x86_64. Since the merge, the x86_64 sequence is unchanged, but the i386 sequence is now like x86_64. I prefer this consistency, and I prefer the new sequence: booting with maxcpus=2 then uses the independent physicals without HT sharing.

Once all the X drivers move to ioremap_wc(), we can go back to strong UC semantics for ioremap() and ioremap_nocache(). To avoid attribute aliasing issues, pci_mmap_page_range() will also use UC_MINUS for default non write-combining mapping request. Next steps: a) change all the video drivers using ioremap() or ioremap_nocache() and adding WC MTTR using mttr_add() to ioremap_wc() b) for strict usage, we can go back to strong uc semantics for ioremap() and ioremap_nocache() after some grace period for completing step-a. c) user level X server needs to use the appropriate method for setting up WC mapping (like using resourceX_wc sysfs file instead of adding MTRR for WC and using /dev/mem or resourceX under /sys) Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-30x86: use defconfigs from x86/configs/*Sam Ravnborg
Daniel Drake <dsd@gentoo.org> reported: In 2.6.23, if you unpacked a kernel source tarball and then ran "make menuconfig" you'd be presented with this message: # using defaults found in arch/i386/defconfig and the default options would be set. The same thing in 2.6.24 does not give you any "using defaults" message, and the default config options within menuconfig are rather blank (e.g. no PCI support). You can work around this by explicitly running "make defconfig" before menuconfig, but it would be nice to have the behaviour the way it was for 2.6.23 (and the way it still is for other archs).
