2007-03-11Fix buffer overflow in Omnikey CardMan 4040 driver (CVE-2007-0005)Marcel Holtmann
Based on a patch from Don Howard <dhoward@redhat.com> When calling write() with a buffer larger than 512 bytes, the driver's write buffer overflows, allowing to overwrite the EIP and execute arbitrary code with kernel privileges. In read(), there exists a similar problem, but coming from the device. A malicous or buggy device sending more than 512 bytes can overflow of the driver's read buffer, with the same effects as above.

2007-03-11IB/mthca: Fix off-by-one in FMR handling on memfreeMichael S. Tsirkin
From: Michael S. Tsirkin <mst@mellanox.co.il> mthca_table_find() will return the wrong address when the table entry being searched for is exactly at the beginning of a sglist entry (other than the first), because it uses >= when it should use >. Example: assume we have 2 entries in scatterlist, 4K each, offset is 4K. The current code will return first entry + 4K when we really want the second entry. In particular this means mapping an FMR on a memfree HCA may end up writing the page table into the wrong place, leading to memory corruption and also causing the HCA to use an incorrect address translation table.

2007-03-11IPoIB: Rejoin all multicast groups after a port eventEli Cohen
When ipoib_ib_dev_flush() is called because of a port event, the driver needs to rejoin all multicast groups, since the flush will call ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()). Otherwise no (non-broadcast) multicast groups will be rejoined until the networking core calls ->set_multicast_list again, and so multicast reception will be broken for potentially a long time.

2007-03-11IB/mthca: Use mmiowb after doorbell ringArthur Kepner
We discovered a problem when running IPoIB applications on multiple CPUs on an Altix system. Many messages such as: ib_mthca 0002:01:00.0: SQ 000014 full (19941644 head, 19941707 tail, 64 max, 0 nreq) appear in syslog, and the driver wedges up. Apparently this is because writes to the doorbells from different CPUs reach the device out of order. The following patch adds mmiowb() calls after doorbell rings to ensure the doorbell writes are ordered.

2007-03-08video/aty/mach64_ct.c: fix bogus delay loopDavid S. Miller
CT based mach64 cards were reported to hang on sparc64 boxes when compiled with gcc-4.1.x and later. Looking at this piece of code, it's no surprise. A critical delay was implemented as an empty for() loop, and gcc 4.0.x and previous did not optimize it away, so we did get a delay. But gcc-4.1.x and later can optimize it away, and we get crashes. Use a real udelay() to fix this. Fix verified on SunBlade100. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Adrian Bunk <bunk@stusta.de>

2007-01-23read_zero_pagealigned() locking fixHugh Dickins
Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel bugzilla 7645. Right: read_zero_pagealigned uses down_read of mmap_sem, but another thread's racing read of /dev/zero, or a normal fault, can easily set that pte again, in between zap_page_range and zeromap_page_range getting there. It's been wrong ever since 2.4.3. The simple fix is to use down_write instead, but that would serialize reads of /dev/zero more than at present: perhaps some app would be badly affected. So instead let zeromap_page_range return the error instead of BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in that case - there's no need to optimize for it. Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of zeromap_page_range), though it really isn't interesting there. And since mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that than -ENOMEM. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Adrian Bunk <bunk@stusta.de>
