2009-01-31Fix memory corruption in console selectionMikulas Patocka
Fix an off-by-two memory error in console selection. The loop below goes from sel_start to sel_end (inclusive), so it writes one more character. This one more character was added to the allocated size (+1), but it was not multiplied by an UTF-8 multiplier. This patch fixes a memory corruption when UTF-8 console is used and the user selects a few characters, all of them 3-byte in UTF-8 (for example a frame line). When memory redzones are enabled, a redzone corruption is reported. When they are not enabled, trashing of random memory occurs.

2009-01-31Stop playing silly games with the VM_ACCOUNT flagLinus Torvalds
The mmap_region() code would temporarily set the VM_ACCOUNT flag for anonymous shared mappings just to inform shmem_zero_setup() that it should enable accounting for the resulting shm object. It would then clear the flag after calling ->mmap (for the /dev/zero case) or doing shmem_zero_setup() (for the MAP_ANON case). This just resulted in vma merge issues, but also made for just unnecessary confusion. Use the already-existing VM_NORESERVE flag for this instead, and let shmem_{zero|file}_setup() just figure it out from that. This also happens to make it obvious that the new DRI2 GEM layer uses a non-reserving backing store for its object allocation - which is quite possibly not intentional. But since I didn't want to change semantics in this patch, I left it alone, and just updated the caller to use the new flag semantics. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-01-31igb: fix link reporting when using sgmiiAlexander Duyck
When using sgmii the link was not being properly passed up to the driver from the underlying link management functions.

2009-01-31igb: prevent skb_over panic w/ mtu smaller than 1KAlexander Duyck
A panic has been observed with frame sizes smaller than 1K. This has been root caused to the hardware spanning larger frames across multiple buffers and then reporting the original frame size in the first descriptor. To prevent this we can enable set the LPE bit which in turn will restrict packet sizes to those set in the RLPML register.

2009-01-30packet: Avoid lock_sock in mmap handlerHerbert Xu
As the mmap handler gets called under mmap_sem, and we may grab mmap_sem elsewhere under the socket lock to access user data, we should avoid grabbing the socket lock in the mmap handler. Since the only thing we care about in the mmap handler is for pg_vec* to be invariant, i.e., to exclude packet_set_ring, we can achieve this by simply using a new mutex.

2009-01-30sfc: Replace stats_enabled flag with a disable countBen Hutchings
Currently we use a spin-lock to serialise statistics fetches and also to inhibit them for short periods of time, plus a flag to enable/disable statistics fetches for longer periods of time, during online reset. This was apparently insufficient to deal with the several reasons for stats being disabled. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2009-01-30sfc: SFX7101/SFT9001: Fix AN advertisementsBen Hutchings
All 10Xpress PHYs require autonegotiation all the time; enforce this in the set_settings() method and do not treat it as a workaround. Remove claimed support for 100M HD mode since it is not supported by current firmware. Do not set speed override bits when AN is enabled, and do not use register 1.49192 for AN configuration as it can override what we set elsewhere. Always set the AN selector bits to 1 (802.3).

2009-01-30sfc: Test for PHYXS faults whenever we cannot test link state bitsSteve Hodgson

2009-01-30sfc: SFX7101: Remove workaround for bad link trainingSteve Hodgson
Early versions of the SFX7101 firmware could complete link training in a state where it would not adequately cancel noise (Solarflare bug 10750). We previously worked around this by resetting the PHY after seeing many Ethernet CRC errors. This workaround is unsafe since it takes no account of the interval between errors; it also appears to be unnecessary with production firmware. Therefore remove it.
