A user reported seeing occasional bugs such as the following when using the L2TP driver. SKB BUG: Invalid truesize (272) len=72, sizeof(sk_buff)=208 When L2TP adds its header in the transmit path, it might need to increase the headroom of the skb. In some cases, the increased headroom trips a kernel bug when the skb is freed because the skb has grown beyond its truesize value. The fix is to increase the truesize by the amount of headroom added, after orphaning the skb. While here, fix a misleading comment. Thanks to Iouri Kharon <bc-info@styx.cabel.net> for the initial report and testing the fix. Signed-off-by:

This is a fix for OLPC ticket #6586: "SCAN command fails, timer doesn't fire". In fact, the timer was firing; the problem was that the dnld_sent state variable was not being updated after the timer expired, so lbs_execute_next_command was not being called. Signed-off-by:

Since commit e38bad47 mac80211: make ieee80211_iterate_active_interfaces not need rtnl rt2500usb and rt73usb broke down due to attempting register access in atomic context (which is not possible for USB hardware). This patch restores ieee80211_iterate_active_interfaces() to use RTNL lock, and provides the non-RTNL version under a new name: ieee80211_iterate_active_interfaces_atomic() So far only rt2x00 uses ieee80211_iterate_active_interfaces(), and those drivers require the RTNL version of ieee80211_iterate_active_interfaces(). Since they already call that function directly, this patch will automatically fix the USB rt2x00 drivers. v2: Rename ieee80211_iterate_active_interfaces_rtnl Signed-off-by:

Mark Asselstine authored
The use of cli()/sti() within the do/while was a way to ensure interrupts were only disabled for short periods of time while the bulk of the time interrupts were free to occur. The use of the spin lock has eliminated the need to play with interrupts in this way while still allowing for IO to be protected. The remaining 3 sti() calls seem unneeded now that at no other point in the driver is there a call to cli(). Signed-off-by:

The atm_tcp.h uses types from linux/atm.h, but does not include it. It should also use the standard __u## types from linux/types.h rather than the uint##_t types since the former can be found with the kernel already. Same goes for linux/atm.h. The linux/socket.h include there also gets dropped as atm.h does not actually use anything from socket.h. Signed-off-by:

Stephen Hemminger authored
It is possible that the entry in sysfs already exists, one case of this is when a network device is renamed to bonding_masters. Anyway, in this case the proper error path is for device_rename to return an error code, not to generate bogus backtrace and errors. Also, to avoid possible races, the create link should be done before the remove link. This makes a device rename atomic operation like other renames. Signed-off-by:

As setting and clearing queue flags now requires that we hold a spinlock on the queue, and as blk_queue_stack_limits is called without that lock, get the lock inside blk_queue_stack_limits. For blk_queue_stack_limits to be able to find the right lock, each md personality needs to set q->queue_lock to point to the appropriate lock. Those personalities which didn't previously use a spin_lock, us q->__queue_lock. So always initialise that lock when allocated. With this in place, setting/clearing of the QUEUE_FLAG_PLUGGED bit will no longer cause warnings as it will be clear that the proper lock is held.

Trying to online a new memory section that was added via memory hotplug sometimes results in crashes when the new pages are added via __free_page. Reason for that is that the pageblock bitmap isn't initialized and hence contains random stuff. That means that get_pageblock_migratetype() returns also random stuff and therefore list_add(&page->lru, &zone->free_area[order].free_list[migratetype]); in __free_one_page() tries to do a list_add to something that isn't even necessarily a list. This happens since 86051ca5 ("mm: fix usemap initialization") which makes sure that the pageblock bitmap gets only initialized for pages present in a zone. Unfortunately for hot-added memory the zones "grow" after the memmap and the pageblock memmap have been initialized. Which means that the new pages have an unitialized bitmap. To solve this the calls to grow_zone_span() and grow_pgdat_span() are moved to __add_zone() just before the initialization happens. The patch also moves the two functions since __add_zone() is the only caller and I didn't want to add a forward declaration. Signed-off-by:

Current module loader lookups ".data.percpu" ELF section to perform per_cpu relocation. But DEFINE_PER_CPU_SHARED_ALIGNED() uses another section (".data.percpu.shared_aligned"), currently only handled in vmlinux.lds, not by module loader. To correct this problem, instead of adding logic into module loader, or using at build time a module.lds file for all arches to group ".data.percpu.shared_aligned" into ".data.percpu", just use ".data.percpu" for modules. Alignment requirements are correctly handled by ld and module loader.

Add a common hex array in hexdump.c so everyone can use it. Add a common hi/lo helper to avoid the shifting masking that is done to get the upper and lower nibbles of a byte value. Pull the pack_hex_byte helper from kgdb as it is opencoded many places in the tree that will be consolidated. Signed-off-by:

This fix the uninitialized bs when we try to replace a xattr entry in ibody with the new value which require more than free space. This situation only happens we format ext3/4 with inode size more than 128 and we have put xattr entries both in ibody and block. The consequences about this bug is we will lost the xattr block which pointed by i_file_acl with all xattr entires in it. We will alloc a new xattr block and put that large value entry in it. The old xattr block will become orphan block. Signed-off-by:

I noticed this because alpha was broken due to the recent commit commit bdc80787 ("avoid overflows in kernel/time.c"). Most arches do something like this in their asm/param.h: #ifdef __KERNEL__ # define HZ CONFIG_HZ #else # define HZ 100 #endif A few arches though (namely alpha/h8300/um/v850/xtensa) either do no set HZ at all for !__KERNEL__, or they set it wrongly. This should bring all arches in line by setting up HZ for userspace. Without this currently perl 5.10 doesn't build on alpha: perl.c: In function 'perl_construct': perl.c:388: error: 'CONFIG_HZ' undeclared (first use in this function) -> http://buildd.debian.org/fetch.cgi?pkg=perl;ver=5.10.0-10;arch=alpha;stamp=1210252894Signed-off-by:

Updating the current transaction's t_state is protected by j_state_lock. We need to do the same when updating the t_state to T_COMMIT. Signed-off-by:

__add_zone calls memmap_init_zone twice if memory gets attached to an empty zone. Once via init_currently_empty_zone and once explictly right after that call. Looks like this is currently not a bug, however the call is superfluous and might lead to subtle bugs if memmap_init_zone gets changed. So make sure it is called only once.

The current OF probing assumes that the resource is IORESOURCE_MEM. This checks for the IORESOURCE_IO flag and behaves appropriately. An I/O resource can exist with an ipmi device node on a legacy ISA bus. Signed-off-by:

Fix initialization of framebuffer not calling ioremap_writecombine() function and not using internal SRAM for at91sam9rl. This is a little rework of the "Don't initialize a pre-allocated framebuffer" patch that corrects the call to ioremap_writecombine() function. It also cuts the use of internal SRAM for at91sam9rl : it is a bit small for a framebuffer. Signed-off-by:

filemap_fault will go into an infinite loop if ->readpage() fails asynchronously. AFAICS the bug was introduced by this commit, which removed the wait after the final readpage: commit d00806b1 Author: Nick Piggin <npiggin@suse.de> Date: Thu Jul 19 01:46:57 2007 -0700 mm: fix fault vs invalidate race for linear mappings Fix by reintroducing the wait_on_page_locked() after ->readpage() to make sure the page is up-to-date before jumping back to the beginning of the function. I've noticed this while testing nfs exporting on fuse. The patch fixes it. Signed-off-by:

The AD181x and AZT230 chips don't support an IRQ-less MPU401 option but work fine without one. This adds (priority functional) IRQ-less options for each port option to help systems with few available IRQs. The AD1815 quirk can't use pnp_register_irq_resource() due to doubly penalizing the IRQ. Also, while not a practical issue due to no IRQ option being present for the dependents, this needs to add in front, not back. Doesn't use pnp_register_port_resource() for symetry with above. This does not delete the AD1815 independent option even though it should be empty after the IRQ transfer due to AD1816 coming with an empty but still present independent option by default. Was tested on AD1815, AD1816 and AZT2320. The ALSA snd-ad1818a driver also support the AZT2002 ID for MPU401 but this doesn't as I was unable to test it. Signed-off-by:
