This is the code to load packet data into a register: k = fentry->k; if (k < 0) { ... } else { u32 _tmp, *p; p = skb_header_pointer(skb, k, 4, &_tmp); if (p != NULL) { A = ntohl(*p); continue; } } skb_header_pointer checks if the requested data is within the linear area: int hlen = skb_headlen(skb); if (offset + len <= hlen) return skb->data + offset; When offset is within [INT_MAX-len+1..INT_MAX] the addition will result in a negative number which is <= hlen. I couldn't trigger a crash on my AMD64 with 2GB of memory, but a coworker tried on his x86 machine and it crashed immediately. This patch fixes the check in skb_header_pointer to handle large positive offsets similar to skb_copy_bits. Invalid data can still be accessed using negative offsets (also similar to skb_copy_bits), anyone using negative offsets needs to verify them himself. Thanks to Thomas Vögtle <thomas.voegtle@coreworks.de> for verifying the problem by crashing his machine and providing me with an Oops.

Patch from Catalin Marinas The range for the ARMv6 block cache operations is inclusive but the kernel doesn't re-calculate the end address, causing a page fault when used (this only happens with support for cache aliasing, otherwise the blk_flush_kern_dcache_page() is not called). This patch subtracts L1_CACHE_BYTES from the end address. Signed-off-by: NCatalin Marinas <catalin.marinas@arm.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Patch from Ben Dooks The request_irq() function is called by s3c24xx uart driver with the local IRQs disabled. The request_irq() function can allocate memory via kmalloc(), and this may sleep causing a warning about sleeping in an invalid context.

由 Rob Punkunus 提交于
From: Rob Punkunus <rpunkunus@nvidia.com> Rob Punkunus recently submitted a patch to enable support for MCP51/MCP55 in the amd74xx driver. This patch was whitespace-corrupted and didn't apply to 2.6.12 since MCP51 support was merged in the 2.6.12-rc series. Gentoo would like to support this hardware for our upcoming release media, so I fixed the patch, and here it is :) Signed-off-by: NDaniel Drake <dsd@gentoo.org> Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@elka.pw.edu.pl>

That zero just means that nothing else found any irq information either.

This fixes the bug that caused BUG_ON(!irqs_disabled()) to trigger in run_posix_cpu_timers() on alpha/smp. We didn't disable interrupts properly before calling smp_percpu_timer_interrupt(). We *do* disable interrupts everywhere except this unfortunate smp_percpu_timer_interrupt(). Fixed thus. Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

As usual, the reason of this breakage is quite silly: in do_entIF, we are checking for PS == 0 to see whether it was a kernel BUG() or userspace trap. It works, unless BUG() happens in interrupt - PS is not 0 in kernel mode due to non-zero IPL, and the things get messed up horribly then. In this particular case it was BUG_ON(!irqs_disabled()) triggered in run_posix_cpu_timers(), so we ended up shooting "current" with the bursts of one SIGTRAP and three SIGILLs on every timer tick. ;-)
